Bottom Pour Systems
Multicast
Capital Refractories has introduced their patented Multicast system for use in ladles with a re-usable lining. This utilises a re-usable isostatically pressed graphitised alumina stopper rod, which typically lasts a minimum of around 10 fills - depending on alloy and temperature. The stopper-rod requires setting only once, resulting in a considerable saving in labour. A disposable fibre gasket (patented) is employed to prevent sticking and leaking. Figure 1 compares the two ladle systems.
The Multicast system requires the use of a re-usable chemically bonded high alumina nozzle. The deterioration of the nozzle means that typically, depending on alloy, a nozzle with the Multicast system can be expected to last a minimum of 5 fills before it needs replacing. At this time, the selection of the nozzle bore size will be influenced, where possible, by the planned castings during the lifetime of the nozzle.
The Advantages of the Multicast System
- Reduction in labour cost, i.e. no need to re-set stopper and nozzle after each cast.
- Reduction in cost of consumables, i.e. the graphitized mono-block stopper will last 10 taps and the nozzle will last around 5 taps.
- Reduction in the cost of ladle lining, i.e. monolithic ladle lining with reduced thermal cycling reduces maintenance and extends the ladle lining life.
- Reduction in patching and repair materials due to high strength low cement castable linings. Also reverse taper nozzle requires virtually no fixing cement.
- Reduction in pre-heat costs since ladle can be used continuously.
- Greater ladle availability due to one ladle in use continuously thereby reducing ladle inventory.
- Reduction in waste costs due to extended life of refractories.
- Reduction in scrap rates due to reduced refractory inclusion, hotter ladle and more consistent metal stream
Unibore
Capital Refractories' patented Unibore nozzle system has been developed and introduced to complement Multicast - the proven reusable stopper system. This unique two component system consists of a re-usable outer nozzle and a second inner nozzle, which is available with a range of bore diameters; a fibre gasket makes the seal between the two pieces. This offers a new method of changing the diameter of the nozzles after each cast by replacing the inner part of the nozzle only.
Unibore's unique two-piece nozzle is fundamentally different to conventional one-piece nozzles.
There are two major differences:
The first is that there is a much larger opening of the outer section of the nozzle compared to a standard nozzle.
The second difference is the tapered design of the inner nozzle, which is available with a range of bore diameters. Nozzles are quickly and easily changed with the operative working from the outside of the ladle away from the effects of heat. During the process, the one-piece stopper remains in place and does not need resetting.
Unibore offers the following advantages:
- Reduced consumable costs: notably stoppers, nozzles and filters.
- Quicker, more stable and controllable metal flow.
- Potential to improve the quality of the casting.
- Reduced vortexing and drag.
- The flexibility of selecting the correct bore diameter for the planned castings.
- Quicker turn-round of ladle.
- Reduced preheating between melts.
- Reduced labour costs from set up of ladle and stoppers.
- Reduced ladle inventory.
- Can be used with most bottom pour ladles.
In addition to the nozzle diameter flexibility, there are potential technical benefits in converting to the system. The large opening of the outer section reduces drag from the stopper and nozzle reducing flow rate fall off. Customer tests have also shown that mould washing is reduced, probably due to a reduction in vortexing from the tapered design of the inner nozzle. This can result in an improvement in quality and a reduction in rework of castings.
Due to the reduced drag of metal through Unibore, metal flow rates are higher than with conventional nozzles. Thus in order to achieve similar flow rates, a smaller diameter Unibore nozzle is usually employed. This is shown in the figure on the right which was compiled from exhaustive comparative trials carried out at a major UK foundry.
Unibore is available with a wide range of bore sizes from 25 to 100 mm.
Unibore has been trialled and adopted by many steel foundries in the UK and overseas with great success: reducing defects and improving the scrap rate. All the companies have reported improvements in efficiency with cost-effective operation. Ladle inventories have been reduced, optimising ladle operatives' time and offering flexibility that has not been available before. The Unibore system can also be successfully used in non-ferrous applications. Unibore is ideal for auto pour furnace systems allowing more flexibility to the methoding process. All this combined with the potential to improve casting quality and reduced rework, offers a unique opportunity to reduce operating costs in your foundry.
Unibore Autopour
Capital Refractories’ licensed and patented Unibore system, already proven in bottom pour ladles, has been further developed for use with Autopour systems. This unique system utilises a two part nozzle; an outer part which is re-useable and an inner part which offers a wide range of bore sizes. The outer nozzle remains as part of the refractory lining and is changed around once a week. The inner nozzle can be replaced with ease daily and enables the user to alter the bore size for each casting accordingly. The tapered nozzles are far less likely to block than the conventional parallel nozzle. The Unibore system enables a more stable and controllable metal flow and allows for a quicker turn-around of the pouring system. It is complemented by Multicast – Capital Refractories’ reusable stopper system.
Unibore with Autopour has been specifically designed to accommodate a shallow nozzle which caters for the small gap between the Autopour tundish and mould.
The advantages of using Unibore with Autopour include:
- Downtime is reduced. The Unibore inner nozzle can be removed and changed allowing casting to be re-started quickly.
- Labour is reduced due to the reduced changeover time.
- The amount of metal poured can be accurately controlled.
- A higher casting quality.
- Reduction in waste – greater control reduces spillage.
- Unibore with Autopour helps to keep pace with high speed mould machines.
- The system allows for consistent pouring
Gas Diffusers
Capital Refractories are now able to offer an extensive series of gas diffuser products for the treatment of melts across a range hot metal industries.
Gas purging homogenises the melt and can contribute to the purification of the alloy. Homogenisation aims for equalisation of the analysis and temperature of the metal in the vessel. Gas purging can effect rapid distribution and dissolution of alloying and deoxidising agents and quick adjustment of casting temperature can be achieved. Reduction of deleterious gas content and separation of non - metallic inclusions, with subsequent improvement in metal quality resulting from their elimination from the melt.
All Capital Refractories gas diffusers are supplied to suit the customers' requirements with respect to the metal casings and gas feed pipe work, the choice of these being dictated by the application, this being particularly important in aluminium melt applications if there is the possibility of chlorine being used as a purging gas.
Selection
Capital Refractories has pioneered the recent use of gas diffusers in foundries. Capital has un-beatable quality and support.
The plug is best located below the surface of the lining.
Gas diffusers for use in induction furnaces are available in a range of qualities, sizes and fittings. The choice depends on the lining thickness. The standard range for induction furnaces is made with Caperdiff 94 AL (a high alumina quality) and stainless steel cans and are usually available from stock (except IF 6).

Crucible Gas Diffuser
Capital Refractories has now incorporated their gas diffuser technology into a pressed crucible. The resultant metallurgical treatment crucible is a multi-use, isostatically pressed one-piece refractory vessel with an integral gas supply device.
The granulometry of the crucibles walls and base is such that gas can easily travel through it. This allows the gas to enter the metal not just from the base but also the side walls as shown in the animation to the right. The outer wall of the crucible can be coated with an inorganic sealant to inhibit loss of gas through the external surface.
Trials have indicated that these crucibles are very effective in imparting the benefits of gas diffusion to metal: homogenising the melt and removing slag particles to the surface. In many cases, there appears to be a concurrent improvement in vessel life.
Gas consumprion has been proven to be substantially reduced when compared with surface gas blanket techniques.
Capital's crucible gas diffuser is subject to a UK Patent Application No. 07230402
Case Studies
Capital Refractories are now able to offer an extensive series of gas diffuser products for the treatment of melts across a range hot metal industries.
Experience at an Investment Foundry
Capital has converted an investment foundry from chrome-alumina crucibles to Coral SMC fitted with a gas diffuser. Before conversion the crucible would last one day (18-20 heats) before erosion necessitated its replacement. The photographs here show the Coral SMC lining after a day. The lining surface is very clean and overall life much extended. The life expectancy of the furnace is now about 1 week between re-lines.
More Gas Diffuser Success
Capital Refractories has again demonstrated the huge benefits that can be achieved by employing a gas diffusers within an induction furnace. Capital recently worked in conjunction with Weaver Materiel, their distributor in the State of Pennsylvania. The foundry manufacture steel castings for the oil and refining industry, and were looking for a way in which they could de-gas the whole melt rather than having to adopt the SPAL method (i.e. spraying liquid argon onto the top of the melt), therefore reducing their costs and achieving a better surface finish on their castings.
Weaver Materiel installed Capital’s Coral SMC lining along with a standard 3 inch gas diffuser (model 7126). They were on site for the full 2 day trial, instructing all melters and supervisors on the procedures involved with the simple installation and running of the plug. In line with Capital’s policy, all distributors offer ongoing support to their customers if needed.
Benefits reported:
- Huge financial and environmental savings in the gas used.
- Improved surface finish on the castings due to the ability to de-gas through the whole melt.
- Hardly any wear on the Capital lining.
- Easier to pour metal into the moulds – cleaner metal means that pouring can be done faster through the pouring cups and filters.
- Scrap rate reduced.
This Pennsylvanian foundry has since reported a substantial financial saving along with an improvement in the quality of their castings, and have already placed further orders for Capital’s combined lining and gas diffuser product.
A particularly large foundry was one of the first to take advantage of our highly developed gas diffusers for their induction furnace.
Whilst it is well known that gas diffusers can greatly improve metal quality and reduce gases within the melt, it took a lining problem for this company to further investigate this gas treatment solution.
The problem was zonal overheating of the linings, in particular the lower side wall. The brick lining was being heated beyond its capability thereby causing severe wear on the bricks and potentially disastrous fusion of the backing powder.
We introduced our gas diffuser and began passing argon through the melt which caused a stirring effect. This displaced the superheated metal into the remainder of the melt on a continuous basis and therefore homogenised the temperature throughout the bulk of the melt. By eliminating this superheated zone the condition of the bricks at this location improved dramatically with a consequent substantial improvement in lining life. The company now use 8 plugs a month from us.
We are continuing to work with this induction furnace team to improve their production and are looking to install a gas diffuser in the base of the casting ladle shortly.
Benefits:
- A reduced bath temperature
- Reduction of “elephant’s foot”
- Even wear of refractory lining
- Increased life of consumables
A steel foundry was experiencing quality problems with a high scrap and reclamation rate. Defects in the metal were particularly apparent on the top face. It was thought to be due to dissolved nitrogen coming out of the solution which could be reduced by flushing with argon.
A Capital plug was introduced in the base of the foundry’s 300 kg furnace and there was a large improvement in the casting quality of the metals. With over 70 casts undertaken, there was found to be only a slight deterioration of the plug with no wearing of the lining.
Our gas diffuser is being used successfully with argon at the foundry. Reports suggest that the castings being taken are the foundry’s best quality in history, and the use of our plugs is now standard practice in the Induction Furnace.
Benefits:
- Reduced scrap rate
- Reduced nitrogen levels
- Improvement in cast quality
A large foundry has recently installed a gas diffuser with a specific aim.
The foundry wished to become more economical due to the high scrap rate produced from the 600 kg furnace. Ring castings were also pin-holed and these issues were thought to be due to high levels of nitrogen.
Our plug was installed to be utilised with argon. Use of the plug led to a large reduction in nitrogen levels and the scrapping of castings being halved. Deterioration of linings is also reduced with the use of a gas diffuser. The company are now looking to put plugs in all furnaces which will reduce lining wear, reduce scrap and increase the metal quality.
Metal quality has been hugely improved and the foundry expect glowing reports from their customers about this.
Benefits:
- Reduced Nitrogen levels from 0.42% to 0.22%
- Reduced scrap levels
A company that produce engineering castings for the offshore industry have become yet another satisfied Capital Refractories customer.
This Dutch foundry has recently installed a gas diffuser in their 500 kg furnace. This furnace is used for producing steel castings.
The metal quality is markedly improved and appears far cleaner. There has also been a 30% improvement on the mechanical properties of the metal during low temperature impact testing. Obviously this is significant for the industry for which they cater .
Reports suggest that the company are delighted with our impact on their production, and are looking to install another plug on a furnace used to produce other steel grades shortly.
Benefits:
- Although gas levels remained constant, the impact strength increased as the gas diffuser removed other contaminants (such as sand and refractory inclusions).
- Scrap levels have been drastically reduced.
- Quality of the metal has been vastly improved due to a stainless steel alloy being purged with the gas diffuser.

Vibration Equipment
Capital stock a range of ancillary products to support the installation and operation of our materials, enabling Capital to offer the complete package to our customers.
Pneumatic Internal Former Vibrators - Self Rotating
Installation by former vibrator gives a denser, more consistent and more repeatable installation. Mechanisation reduces the effect of different installers and, by eliminating the need for spiking between layers, means less likelihood of lamination or of tearing the mica sheet, both of which can lead to metal penetration. Less vibration by hand ramming also means less exposure to 'vibrating white finger'.
Vibrating Hand Tools (immersion vibrators)
Capital supply electrical transformers, vibrating hand-held equipment and associated tools - three-pronged fork, crescent and flat-rammer - for the compaction of dry lining and plastic material.

Risers and Application Technology
Regardless whether constructed from exothermic or insulating materials, risers and sleeves are selected purposefully by foundries seeking an increase in productivity and an overall improvement of the casting quality.
|
In the past years, riser technology has clearly developed itself further owing to innovative product solutions. GTP Schäfer have maintained the production of traditional feeder systems and have furthered the advancement of their innovative product portfolio as well. Products such as their THERMO risers and exothermic/insulating sleeves, with and without breaker cores, have contributed to a clear increase in the efficiency and process optimisation of the foundry industry. The modular principle of the point riser portfolio was also supplemented by the development of metallic breaker cores (PX-ME series), which enables an efficient removal of the riser rest in the cleaning phase and makes it possible for the caster to increase the process security. |

THERMO risers
Product features:
THERMO-risers are thick-walled risers which enable feed metal utilisation of up to 60-70%. The properties of the solid riser wall range from highly exothermic to highly insulating, according to the intended application. The optimised material properties and the adapted volume enable substantial improvements in output and economic efficiency. A modulus range between 0.8 cm and around 8 cm can be covered with risers from this product segment.
In order to cover this broad modulus range, our formulations are tailored to the different geometries concerned. This enables modulus-specific factors such as firing temperature, ignition, burn-off and heating time to be optimised. The particularly robust design of the THERMO-risers means that they are equally suitable for use in hand moulding shops or in automatic high-pressure moulding lines. Fixed pins or spring-loaded pins can be used, according to the underlying conditions and the application concerned.
The sintering tendency of the riser rests allows them to be separated from the remaining moulding sand virtually in their entirety in the course of the shake-out process. In addition to the broad selection of different riser geometries, a choice of different qualities is also available.
Area of application:
The classic fields of application for our exothermic THERMO-risers are cast iron with flaky and spheroidal graphite and cast steel. The available ISO qualities also extend the range of applications to non-ferrous metals.
Classification of different types:
- With continuous hole in top – “T”
- Without continuous hole in top & particularly good moulding sand compacting – “TG”
- Self-centering variant – “TG/Z”
- Compact design with oval exterior form “OT”
Breaker cores:
The product segment is complemented by a broad range of different breaker cores to enable optimum adaptation of the riser systems to our customers’ requirements.
- "EQ": Round support surface, round neck, high strength
- "EQ/S": Breaking edge on casting, round support surface, round neck, high strength
- "EQ/ov": Oval support surface, oval neck, high strength
- "EQ/ovS": Breaking edge on casting, round support surface, oval neck, high strength
- Special breaker cores available on request
Contour breaker cores in Croning sand
- “ESQ key breaker cores” – reduced support surface, round neck, high strength
- Round/oval neck, high strength
- “RQ/R, EQ/R” breaker cores with radial contact surface
POINT risers
Product features:
POINT risers® are thick-walled risers which enable feed metal utilisation of up to 60-70%. They have been developed especially for demanding applications in modern high-pressure moulding lines. The properties of the solid riser wall range from highly exothermic to highly insulating, according to the intended application. The optimised material properties and the adapted volume enable substantial improvements in output and economic efficiency.The self-centering inner contour ensures fast charging of the pattern plate with risers in sync with the moulding plant. The small neck of the riser only requires the area of the metal connection channel between casting and riser. In contrast to risers with a breaker core, this enables absolutely accurate positioning of the riser. These risers can thus be used on the smallest items, such as cams or fins.
During pouring of the moulding sand into the moulding box, the POINT risers® are initially held up by a pin. As the moulding sand is compacted, the riser is moved in the direction of the pattern, thus compacting the moulding sand between riser and pattern. The casting contour under the riser is produced by the moulding sand which is moulded between riser and casting in the form of a breaker core. The neatly formed casting contour is only interrupted by the small metal riser neck.
Modular principle:In the course of development of the POINT risers® the self-centering risers have been bonded with exothermic reducing plates and with flat and hat-type metal disks which are similar to key breaker cores. This product variety provides foundries with a broad choice of innovative solutions.
POINT risers with metal neck (MS)In order to meet the increasing requirements of semi-automatic high-pressure moulding lines with their ever higher compacting pressure coupled with more complex casting geometries and correspondingly exposed riser positions, the POINT risers® can be provided with a flat metal disk of 1-2 mm in thickness. While performing the same function as the reducing plates, the MS disks are more robust in design.
|
POINT risers® with metal breaker core
The PX-ME N series comprises POINT risers® with a metal breaker core – an outward-arching metal disk which is fixed to the body of the riser. This combines minimum volume with maximum output and ensures more reliable processes in high-pressure moulding lines in particular.The metal disk produces a predefined breaking edge directly above the contact surface. The required contact area for the riser can be reduced to the metallic cross-section of the riser neck.
The defined breaking point enables efficient removal of the riser rest in the cleaning department and the minimal contact area of the ME disk eliminates the need for extensive grinding of the casting in the direct vicinity of the riser.
Particularly in exposed positions such as flanges with minimal contact areas, use of the “PX-ME N” avoids the need for a larger contact area which will require extensive finishing after the actual casting process.
The metal disks are available in diameters of 15 mm to 40 mm. Metal disks with an oval hole (MEov N) have additionally been developed for particularly narrow, exposed contact surfaces such as flanges.
ECO risers
Energy efficiency in the riser system
With respect to performance and competitiveness, foundries and their supplier industries cannot turn their backs on the global trend to use resources more efficiently and to optimize raw materials and auxiliary resources. Great potentials can be found in the field of energy efficiency in the context of energy intensity of production processes in foundries. In addition to melting, additional energy is needed and accordingly supplied at various points in the production process. The riser system is one of the main points in the process where extra energy is added. Nowadays, solidification control is achieved primarily with exothermic feeder sleeves that are used for point heating of the feeder metal, thus enabling feeding relevant nodes of the cast part. Here, the exothermic reaction of the feeder material adds extra energy to the process while additional liquid metal is kept ready in the riser system for feeding.
The basic design principle of the ECO riser is a combination of exothermic inner riser, which holds the liquid iron for feeding, and an insulating cover that reduces heat transfer to the environment of the riser and thus greatly increases energy efficiency. The supply of additional energy thus can be reduced and at the same time the efficiency of the product can be increased. This riser system was consistently further developed in the last four years in collaboration with Georg Fischer, Leipzig, and different ECO risers with a module range from 1.9 cm to 4.5 cm are now available as series products.
Moreover, you can trace the development of the ECO riser on the basis of various articles published by GTP Schäfer.

Special breaker cores
Experience shows that it is frequently necessary to develop special breaker cores tailored to customers’ individual needs. The geometry of the breaker core can then be matched precisely to the contours of the casting concerned.
The production of such customised breaker cores often results in vast cost savings in the working and machining process which exceed the additional costs of the breaker core many times over
Qualities
The riser additives employed today are produced from insulating and/or exothermic materials.
The exothermic materials are based on Goldschmidt’s process, which is also referred to as the aluminothermic process. The aluminothermic reaction between aluminium and oxygen, which originates in part from the added iron oxide, releases a large quantity of heat.
Fluorine compounds in small quantities serve as a catalyst for this reaction. In order to prevent the powders from slagging as a result of the high temperatures, the reaction has to be moderated. This is achieved by diluting the exothermic components with various fillers.
Heating, welding and anti-piping powders are based on this aluminothermic reaction, in the course of which very high temperatures are generated.
THERMEX
Our standard material THERMEX is a highly exothermic, quickly igniting riser material of extremely high stability. After the reaction, the riser body possesses a high pore volume and good insulating properties. The characteristic EXO values such as ignition and burning time are adapted to the modulus of the risers.The THERMEX qualities have been developed especially for use on modern high-pressure moulding lines and thus possess a high level of mechanical stability.
THERMEX „FA“
THERMEX “FA” was developed to help our customers reduce the fluorine content in the sand system. This material offers an exothermic capacity comparable to THERMEX and identical properties, but with a reduced level of fluorine content.THERMEX „FF“
This is a highly stable fluorine-free riser material. Its properties are roughly comparable to those of THERMEX. Fluorine is substituted in this riser material.THERMEX „CB“
THERMEX “CB” is a low-fluorine and exothermic/insulating riser material of good stability and reduced weight. Due to the high level of high-quality insulating materials contained in this agent, the riser body possesses a high pore volume and excellent insulating properties after the reaction. The characteristic EXO values are adapted to the modulus accordingly.
THERMISO
THERMISO is an insulating riser material which, in addition to its main area of application at non-ferrous foundries, has also been developed for special steel casting applications. The high proportion of high-quality insulating materials enables the riser modulus to be extended.Ceracat +
CERACAT+ foam foundry filters are produced from high temperature Ceramic plus an addition of Carbon which increases Thermal Shock, temperature and chemical resistance to the liquid metal. They are recommended as a highly cost effective replacement for Zirconia and Carbon bonded foundry filters in many Steel and Iron applications.CERACAT+ foundry filters when correctly designed into a gating system help to remove inclusions from the metal stream and reduce turbulence preventing the risk of erosion and re-oxidation, thus reducing surface and subsurface defects on castings reducing finishing costs and in many applications increasing casting yield and mechanical properties of the metal.
CERACAT+ has the following benefits:
> High Strength
> Excellent Thermal Shock Resistance
> High Oxidation and Moisture resistance compared to Carbon bonded Filters
> Low Carbon content, no measurable Carbon pickup in steel
> Economic Pricing

A Range of Phenolic Resin based adhesive for Hot to Hot bonding of Croning Shell MouldsThe HEXACURE range of adhesives are based on blends of Phenolic Resin and Minerals in a Base Oil carrier. They are delivered as a pumpable flowing liquid that will not boil or dry out to quickly when applied to the hot shell mould allowing the operator sufficient time to properly position the top half of the mould and after 30-60 seconds of curing under pressure in the mould press Hexacure develops a strong bond which eliminates metal run outs at the parting line.
There are many Hexacure grades available with the following variables:
Viscosity (depending on application technique, bead size and spread on closure)
Reactivity (depending on cycle speed, temperature, thickness of mould i.e.. The amount of heat available for curing) Bond Strength
Please contact CAT for advice on best grade for your requirement or custom blending for your process.

Coatings
CLEANCAST mould and core coatings
Foundry coatings cover a wide range of applications from resin bonded sand cores and moulds, Iron ingot moulds, refractory launders to non ferrous die casting and even non wetting ladle coatings.What they all have in common is that they provide a thin barrier (usually less than 0.5mm) between the liquid metal and substrate they are applied to. They are a critical consumable in any cast metal plant and can have a significant impact on the production costs and quality of your castings
CLEANCAST alcohol and waterbased mould and core coatings
CLEANCAST waterbased Ingot mould and launder coatings
DYTEK Die coatings for gravity and low pressure diecasting
ALICAT Non wetting coating for steel ladles and tools used in non ferrous foundries

Sand Binders
OBB Sand
O.B.B.-Sand "E" is an oil-bonded moulding sand. It is delivered ready for use and does not dry out. Its high green strength permits the most arduous moulding conditions while maintaining absolute dimensional and contour accuracy.Application:
Mainly non ferrous metal, as well as grey iron and spheroidal iron for castings with thin and average wall thickness.
The first layer of sand should be sieved on the pattern and be pressed on slightly. The moulding box can then be filled up with unsieved sand. Do not add water or coatings.
Special characteristics:
Beside the standard quality it is possible to produce sands with either a higher or lower flowability. For higher flowability Grade O.B.B.-Sand "EM", or lower flowability Grade O.B.B.-Sand "EF"). There are two different ways for using our O.B.B.-Sand. Either our sand is used only for the first layer, then it will mix with the usual moulding sand and can not be recovered. Or our O.B.B. – Sand is used as a unique sand, it is then possible to reclaim the sand with O.B.B.-Oil and –Paste.

Die Coatings
Dytek
Die coatings for gravity and low pressure diecasting
The DYTEK range is suitable for the coating of dies and tools in Gravity/Permanent mould and Low Pressure die casting applications.They are waterbased and generally sprayed but can be dipped or brushed. Depending on the grade DYTEK can influence the following properties:> Increase metal flow in the die
> Control heat transfer
> Improve release of the part from the die
> Improve surface finish
> Increase die life
Ladle Coating
A coating for protection of Steel Ladles/Tools for use in liquid aluminium
Provides a durable coating that protects the steel from the liquid aluminium and prevents aluminium from sticking and forming ‘skulls‘. The use of this coating increases the life of the ladle and in many cases foundries have been able to switch to cheaper mild steel ladles rather than stainless
Alicat is a smooth white brushable paste based on Titanium Dioxide. It can be applied to hot or cold surfaces but must be dried before use, usually done over the furnace.
When heated ALICAT becomes bright yellow

10 12 1487 True False AdRotary Sand / Casting Separators
Method of OperationPoured molds are delivered into the intake end of the rotary drum. As the molds tumble through the drum, the sand is separated from the casting, crushed to grain size, and dissipated through apertures in the lining to the outer chamber, where it is conveyed to the sand discharge point. The cleaned castings travel to the casting discharge end of the drum, where they exit and move to the next stage of processing in the cleaning room. The tumbling action in the DIDION crushes sand lumps, removes core butts, and empties sand pockets. The apertures in the patented lining act as a rotary screen to prevent tramp metal, core butts, and other foreign material from entering the sand system. Moreover, the sand is homogenized and uniform in temperature, since cooler sand from molds entering the DIDION is constantly mixed with hotter sand as it passes through the lining into the sand chamber. This allows for better sand control at the muller.
Durability
The rugged, unitized construction of the DIDION is designed with dependability and simplicity in mind. Wear and tear, along with energy consumption, have been reduced to a minimum. All component parts are standard items which may be purchased through local sources or from DIDION International Inc. The liner segments are wear-resistant, alloyed ductile iron designed for long life and may be replaced either individually or as a complete lining, according to installation requirements. The DIDION provides increased reliability and production time for the foundry as a result of the design simplicity of the drum. The DIDION Rotary Sand Casting Separator is a low maintenance piece of equipment with approximately eight hours per year required for regular servicing.
Adaptability
The DIDION is designed for use in any type of molding system-from conventional to automatic. The configuration of the lining is specifically designed for each installation in order to provide the most efficient separation of sand and castings, while minimizing excess tumbling of the castings. Standard sand discharge locations at either end of the unit provide easy installation into new or existing foundry systems. A custom-designed intermediate sand discharge (located at almost any point along the drum) will allow sand to be discharged onto existing sand return conveyors.

Sand Processing
Core Sand Treatment
Core Sand Mixer
The KLANN Core Sand Mixers are compact batch mixers with a high productivity, which are offered in a varity of volumes. The sand removal is executed by tilting of the mixer drum. This design has no flaps or slides which could plugg or block. The arrangement of the mixer tools and the design of the drum bottom ensure intensive mixing with low power consumption.
The mixers are available with volumetric or gravimetric dosing devices.
Sand Deduster/Cooler
The quality of core sand is dependant on the binder and the processing equipment, but the quality of raw sand and temperature are also crucial. Dust particles in the sand not only decreases the gassing capacity of the core but also consumes more binder due to the high specific surface. To separate the dust from the sand KLANN provides fluidised bed separators, which can also be used to cool or heat raw sand to optimum temperatures in the range of 20 - 30 °C.
Core Fraction Recycling Unit
To avoid deposit costs for core residues Klann developed a special recycling unit which recovers the sand in different process steps. After grinding of the agglomerates, the impurities are separated by screening and the dust fraction is taken out by air flow separation. After this recycling process up to 10 % of the raw sand feed can be replaced by this recycled core-sand.

Raw Material Storage
Supply of complete silo installations, starting from silo-truck pneumatic unloading and going to material discharge, including the necessary instruments and filter units.
Binder Dosing / Storage
Binder Storage and Dosing
As binder agents used for the core-shooting process have to be stored in accordance with water protection legislation, special considerations must be taken into account for the design of binder storage and dosing facilities. To this end the company KLANN offers variety of storage and dosing equipment, which meet the environmental protection requirements.
Drum Storage
For smaller core shops the binder is mostly delivered in drums, which have to be stored and connected to the dosing equipment. Using a special level gauge device in these drum storages, new binder agents can be ordered in good time.
Container Storage
When using larger quantities of binders in the core shop, containers are used for delivery and storage. Special racks are offered by KLANN for container storage allowing easy exchange and connection. To catch up spillages at the connection points special drawers are installed underneath, which can be easily cleaned. In case of leakages a pan is installed on the rack bottom to catch drips under the complete container volume. The binder is transferred to the dosing station by a sealed double-membrane pump, which is easy accessible.
Binder dosing equipment
In order to assure an exact dosing of the binder components into the mixer special piston pumps are used, these are installed in a cabinet. The set points of the binder volumes can be modified by the PLC. An intermediate reservoir on top of the pumps avoids air suction by the pumps.
Core Handling
Core Handling
Beside a precise handling, the fully automated handling and processing of cores requires peripheric installations offering high reproductibilty.

Synthetic graphite/Electrode graphite
PRODUCT INFORMATION
Synthetic graphite is not only produced to make graphite electrodes for the steel industry, but also in the graphitisation of certain low-ash types of coke. The raw materials are calcined petroleum coke and needle coke. The content of sulphur, nitrogen and volatile components is minimised in graphitisation furnaces at high temperatures of 2400-3000°C. This creates graphite with its unique hexagonal and crystalline layered structure.APPLICATION
We sell our synthetic graphites worldwide under the RANCO name. They are perfect as carburising agents for grey cast iron (EN-GJL), nodular cast iron (EN-GJS) and cast steel (EN-GS) and are used to adjust to the correct carbon content in the liquid iron. There are various types of carburising agents, which differ in quality, shape and grain size The solubility of the carbon depends on the relationship between the degree of saturation of the melt, temperature and time. Other influencing factors include the furnace size, bath movement, proportion of slag in the melt and sulphur content.ADVANTAGES OF RANCO® PRODUCTS
Advantages of our synthetic graphite:
- A high degree of purity of at least 99% carbon and the particle morphology guarantee efficient dissolution in the melt.
- Low levels of sulphur and nitrogen
- Positive effect on the germ balance in the formation of nodular graphite (EN-GJS) and support of the inoculating effect against chilling.
- Grain sizes individually adapted to the size of the melting unit
GRAIN SIZE
The optimum grain size depends on the melt aggregate and the time of addition to the melt. Standard grain sizes are 0.2-1 mm, 0.2-4 mm, 1-4 mm, 3-8 mm and pellets.Calcined Petroleum coke SK
PRODUCT INFORMATION
Petroleum coke is a carbon by-product of the petroleum refining process of thermal decomposition or “cracking” of the high-boiling hydrocarbon molecules contained in mineral oil and their subsequent coking at high pressure. For subsequent industrial use, the petroleum coke must be thermally cleaned in a “calciner” at temperatures of approx. 1400°C. The “calcined petroleum coke” is thus created. In addition to being used as a carburising agent, calcined petroleum coke is used as anode coke in the aluminium industry and in the heat treatment of steel for example.APPLICATION
RANCO petroleum coke is perfect as a carburising agent for grey cast iron (EN-GJL) and cast steel (EN-GS). The purpose is to adjust the correct carbon content in the liquid iron. There are different types of carburisers, varying in quality, shape and size. The solubility of the carbon depends on the relationship between the degree of saturation, the temperature and the time. Other influencing factors include the bath movement of the furnace, the proportion of slag in the melt, the sulphur content of the alloy and carburising agent, and the carbon structure.ADVANTAGES OF RANCO® PRODUCTS
- High carbon content and low levels of volatile components and ash enable efficient carburisation.
- Customised grain sizes available
GRAIN SIZE
The optimum grain size depends on the melt aggregate and the time of addition to the melt. Standard grain sizes are 0.2-1 mm, 0.2-4 mm, 1-4 mm, 3-8 mm and pellets.Special graphites & specialty cokes
PRODUCT INFORMATION
Our synthetic graphites and calcined specialty cokes have almost unique mechanical and thermal properties due to their high purity and ordered crystalline structure. Our products are therefore particularly well suited to improving the performance and comfort of brake pads.APPLICATION
Depending on the design, brake pads contain up to 65 percent metal (e.g., copper, brass, iron), as well as various sulphides, graphite and special cokes, and silicon carbide contained. In addition, they include fibres made of glass, rubber and carbon. Synthetic and natural resins are used as fillers. The interaction of these substances in the matrix gives the brake pad its desired properties.ADVANTAGES OF RANCO® PRODUCTS
Synthetic graphite
- Unique mechanical and thermal properties due to its ordered crystalline structure, improving both performance and comfort
- The heat generated by friction is distributed more evenly over the entire surface of the base or dissipates it into the deeper layers of the base. Hotspots on the lining or the brake disc can therefore be prevented and thermally induced surface deformations reduced, leading to a reduction in noise and vibration and thus increasing comfort.
- Due to its low modulus of elasticity, it has an elasticising effect on the base, which also reduces noise and juddering and lowers wear on the base.
Calcined petroleum coke
- Increases the coefficient of friction and stabilises it over the entire temperature range.
- Helps to reduce unwanted fading and increases braking performance.
- Reduces wear on the brake disc due to the high degree of purity (ash content only 0.2% approx.).
- Reduces vibration and thus noise, which in turn increases comfort.
GRAIN SIZE
In many cases, the grit specifications are developed in close cooperation with the customer. The range extends from ground products to granulated material of up to 2 mm. We would be delighted to help you make your products even better and more successful.Milled Graphite
PRODUCT INFORMATION
Graphite is characterised by a number of unique properties in terms of its electrical conductivity, heat resistance or lubricity and is therefore used in a wide variety of areas. As a rule, finely ground graphite with a fineness of between 2 and 71 µm is required for use in all of these areas. Using the state-of-the-art grinding and classifying systems, Richard Anton KG is able to produce fine grindings according to customer requirements. Grain-size analyses using laser diffraction ensure the highest quality control.APPLICATION
- In lubricating greases as “solid additives”
- In insulating materials for the construction industry
- As a covering agent for copper melts
- In the chemical industry
- In the plastics industry
ADVANTAGES OF RANCO® PRODUCTS
- Excellent lubricity and adhesion
- Corrosion, water and temperature resistance
- Reduction of thermal conductivity in insulating materials
- Acid resistance
- Electric conductivity
GRAIN SIZE
Used in the lubricants industry and for insulating materials and covering materials, special synthetic graphites from Richard Anton KG are produced on high-performance grinding plants in standard fineness ranges of 0-5 my, 0-10 my, 0-20 my, 0-40 my, 0-63 my and 0-71 my and distributed worldwide.Calcined anthracite
PRODUCT INFORMATION
Anthracite (“bright coal” in Greek) is considered to be the highest quality, naturally occurring coal type with a carbon content of over 90%. It occurs during what is termed the “coalification process” of plant components in the absence of air and high pressure and is characterised by its exceptional hardness. Anthracite is mostly used as a fuel because of the high energy content, the hot flame and the virtually residue-free combustion.APPLICATION
Our anthracites are suitable as carburising agents in iron foundries for grey cast iron (EN-GJL), for cast steel (EN-GS) and in steel works. For use as a carburising agent, anthracite is calcined at approx. 1,400°C and thermally cleaned. ADVANTAGES OF RANCO® PRODUCTS High carbon content and low levels of volatile components and ash enable efficient carburisation.GRAIN SIZE
Our standard grits are 1-4 and 4-10 mm.Inoculating carbon
PRODUCT INFORMATION
Long-term inoculant based on a special natural graphite mined for the graphite pre-inoculation of cast iron melts in the production of EN-GJS.APPLICATION
RANCO inoculating carbon is added either to the bottom of the ladle just before tapping the furnace or directly into the pouring stream. The quantity added is approx. 0.3% RANCO® inoculating carbon per quantity of liquid iron.ADVANTAGES OF RANCO® PRODUCTS
In general, inoculants based on iron monosilicide (FeSi), for example, lose about 50% of their effectiveness in the first 5 minutes of holding time of their melt (known as the “decay effect”). Graphitic pre-inoculation with RANCO® inoculant is a safe and reliable method of ensuring the effectiveness of your inoculation remains constant over a longer period of approximately 15 minutes using standard inoculants as the decay effect is suppressed. It has a positive effect on the germ balance and nodular graphite formation. Supercooling during solidification is more controlled and unwanted carbide formation is significantly suppressed. The tendency to chill is reduced considerably, especially in the case of thin-walled and rapidly cooling cross-sections. An optimum combination of graphitic pre-treatment with RANCO® inoculating carbon and conventional inoculants results in an improvement in the mechanical and physical properties, such as the tensile strength, elongation, hardness and machinability of the casting. Significant cost savings can be achieved by reducing rejects and any additional measures such as heat treatment or realloying.GRAIN SIZE
In order to achieve optimum graphitic pre-inoculation, we recommend a grain size of 1-4 mm.Pig Iron – indispensable component in the melt
PRODUCT INFORMATION
Pig iron is obtained by reducing iron ore in a blast furnace. It has an iron content of up to 95%.APPLICATION
Cast in ingots of around 8-15 kg, it is an essential part of the melt in the foundry industry due to its precisely defined analysis.QUALITIES
