Description
Fireclay refractory castables are made of fireclay, binder and additives mixed evenly, with low cost and certain fire resistance and thermal insulation.
High-alumina refractory castables are made of high-alumina bauxite as the main raw material, with high refractoriness, high refractoriness under load, good thermal shock resistance and mechanical strength.

Applications
Fireclay refractory castable is often used in the lining, flue, chimney and other parts of general industrial kilns, withstanding certain temperatures and thermal stresses.
High-alumina refractory castable is mainly used in blast furnaces, electric furnaces, rotary kilns and other equipment in high-temperature industrial fields such as metallurgy, building materials, and chemicals.
High-alumina refractory castables have high refractoriness, high mechanical strength and good thermal shock resistance. So they can resist high-temperature melt erosion, mechanical wear and frequent thermal shock, ensuring stable operation and long life of the equipment.
