Vitcas Castables Refractory consist of standard dense refractory castables predominantly made for use in boilers and furnaces.
Types of refractory castable
The Refractory Concrete is a traditional, concrete and fireclay based refractory for general use in applications such as furnaces, burner blocks and muffle furnaces. It is resistant up to 1600oC.
Vitcas offers a Refractory Castable that is rated to 1700oC. It is a refractory castable produced on the basis of bauxite with a high content of alumina. This Refractory Castable is designed for use in extreme conditions such as in hearth blocks in heating furnaces or inside monolithic steel ladles.
Vitcas also offers the Insulating Refractory Castable for lining furnaces and flues where good insulation is required. The material is characterised by its low density and low thermal conductivity. Its temperature resistance is up to 1300oC. It is not suitable for applications where excessive wear occurs.
