High Alumina Castable Refractory Sand Brown Corundum Castable Refractory Powder
quality high alumina castable refractory Sand Brown Corundum castable Powder
Corundum refractory castable
Corundum high strength wear resistant castable adopts corundum, mullite as main raw materials, ultra fine micro powder, composite binder and additives are added into raw materials. Corundum wear resistant castable features in high strength, good abrasion resistance and excellent thermal shock resistance.
Brown fused Alumina(also know as brown corundum or brown aluminium oxide) is produced by fusion of calcined bauxite in Electric arc furnaces at high temperature of about 2000 degree celsius. The end product has low iron content making it particularly valuable in refractory applications. BFA has a high refactoriness, is extremely hard and stable. It is of compression strength, high toughness, good self-sharping, lower expansion coefficient, no rusty spot, good hydrophily, high cleanliness, heat resistance and chemical stability.
