Product Description:High aluminum castable is a kind of loose dry powder, is based on the traditional ratio, adjust the particle grading, add different additives, reduce the amount of cement, improve the performance, improve the strength of the medium temperature and softening temperature under load, reduce the thermal conductivity, thermal stability is good.
Product Features:High aluminum castable, high temperature performance, high strength.Use a wide temperature range.There is no shrinkage after high temperature, which overcomes the shrinkage characteristics of refractory concrete in the past.Products are easy to store, transport and use.It has the advantages of permeability resistance, erosion resistance, impact resistance, abrasion resistance and good performance, strong integrity of the furnace structure, better air tightness than brick furnace, longer furnace life, save the cost of repair, economic benefits and so on.
