Product Description:
Castable refractories that resist the friction or impact of high temperature solid materials or airflow containing solid powders are called corundum castables.This kind of castable has higher requirements for bending strength and compressive strength, so it is also called corundum high strength wear resistant castable.Product Features:
Corundum castable has high cold and hot strength, good wear resistance, good thermal shock resistance and good volume stability under high temperature.Application:
Corundum castable is mainly used in front of cement rotary kiln, high temperature cyclone separator, lining of circulating fluidized bed, and lining of heating furnace steel groove.|
