Refractory Clay Bricks Fireclay Aluminum Industry Acid Resistant Brick

Description

Fire clay brick refers to the clay products with Al2O3 content of 30%~40%. Fire clay brick can resist the erosion of acid slag and acid gas; have good thermal performance and can withstand rapid cooling and rapid heating. It also has dense bulk density and low porosity. The fire clay bricks are mainly used for aluminum reduction cell and electric furnace.
