Kerui low creep fire clay brick is made of bauxite clinker as the main raw material, added with special additives, and is formed by high-temperature molding and high-temperature firing. It is suitable for the supporting hot air furnace of large, medium, and small blast furnaces.
Performance Characters:
- High bulk density.
- Large heat storage capacity.
- Low creep rate.
Main Application:
It is mainly used in blast furnaces, hot blast stoves, baking furnaces, carbon calciner, coking furnaces, teeming ladle, casting systems, boilers, cement kilns, glass furnaces, and all kinds of kiln linings and thermal equipment. It is applied in metallurgy, machinery, construction, casting, ceramics, electricity, petroleum, chemical industry, etc.
