product introduction:
Corundum silicon carbide wear-resistant castables can also be called high-strength refractory castables and alumina silicon carbide castables. They are generally made of special high-alumina bauxite clinker, white corundum, fused corundum, brown corundum, silicon carbide and other materials as the main raw materials, and are combined with corundum powder, alumina powder, silicon powder, calcium aluminate cement and chemical additives. Since the materials are used in different places with different working conditions, the main materials can be customized in various forms.
Product application:
Corundum silicon carbide wear-resistant castables are widely used in various thermal kiln linings due to their high strength and good wear resistance, especially in those high wear resistance area such as blast furnace slag ditch, dry quenching coke oven, circulating fluidized bed boiler, garbage incinerator, etc.
