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.
1.High fire resistance.
2.Dense bulk density, low porosity.
3.Excellent creep performance at high temperature and good bulk stability.
The fire clay bricks are mainly used for heat boiler, glass kiln, cement kiln, chemical fertilizer gasification furnace, blast furnace, hot blast furnace, coking furnace and electric furnace.
