Parameter of Fire Clay Refractory Bricks

High Working Temperature
Proper Thermal Stability
Strong Acid Resistance
Good Thermal Shock Resistance

Refractory clay bricks are weakly acidic refractory products that can resist the erosion of acidic slag and acidic gas. This also means that they are slightly less resistant to alkaline substances. In addition, clay firebricks have good thermal properties and can withstand rapid cooling and heating.

The main component of fire clay brick is calcined bauxite. Kerui is able to use high purity Al2O3 to produce fireclay brick because the factory is surrounded by rich resources. As a result, the refractory fire clay brick has high quality. Below are main types for your choice. You can also find more information on Kerui YouTube.
