We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of fire clay brick
Kerui low creep refractory clay brick is made of bauxite clinker as the main raw material, with special additives, through high temperature molding and high temperature firing. It is suitable for supporting hot blast stoves of large, medium and small blast furnaces.
Features of fire clay brick
High bulk density.
Large heat storage capacity.
Low creep rate.
Application of fire clay brick
It is mainly used for blast furnace, hot blast furnace, calciner, carbon calciner, coke oven, hot metal ladle, casting system, boiler, cement kiln, glass furnace and various kiln linings and thermal equipment. It is used in metallurgy, machinery, construction, casting, ceramics, power, petroleum, chemical and other industries.
