Our company, offers refractory materials for all the applications in the field of the foundry industry, for heating and subsequent heat treatment of metals.
With respect to its original specialisation in the production of unshaped materials, the company still supplies the materials predominantly in the form of mixtures already prepared for direct processing or further processed by customers by adding water or special binders.
However, the proportion of supplies in the form of already finished components made of castables has been increasing. Those components are tempered at a temperature of >600 °C. Therefore, the customer does not have to produce on site and perform subsequent drying. Thus performed repair is significantly quicker.
The field of application of the refractory materials in the foundry industry is specific as compared to other areas. The refractory material is mostly in direct contact with molten metal and slag. Wear and tear is very high and also very different as per the individual customers – even with the same equipment and the same metal.
A wide field of application of refractory materials includes among others the following:
Cupola furnaces.
Dense, low-cement castables, and castables with a very low content of cement for shaft, hearth, tapping siphon, combustion chamber, and stack
Ramming mixes for hearth and tapping siphon
Ramming and repair mixes for channels
Fore hearth
Ramming mixes for the permanent as well as the provisional lining
Dense, low-cement castables, and castables with a very low content of cement for the permanent as well as the provisional linings
Castables and mixes for repairs of the existing damaged lining
Crucible and channel induction furnaces (grey and nodular cast iron, steel, and non-ferrous metals)
Dense, low-cement castables, and castables with aultra low content of cement for covers
Insulating castable for covers
Ramming mixes for covers
Ramming mixes for the provisional lining
Repair mixes for runners
Self-flowing castables for repairs of bottom and walls
Refractory mastics as binding material for moulded pieces
Crucible pedestals made of low-cement castables and castables with a very low content of cement
Transfer and casting ladles
Ramming mixes for the provisional lining
Insulating castable for the insulating lining
Low-cement castables and castables with a very low content of cement for the provisional lining
Castables chemically bonded and for repairs of pour-out nozzles
Self-flowing castables for repairs of bottom and walls
