High Strength Fire Clay Refractory Brick for Electric Arc Furnace

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.

Fire Clay Brick Application:

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.  

Fire Clay Brick Characteristics:

1.High fire resistance;
2.Dense bulk density;
3.Excellent creep performance at high temperature;
4.Low porosity;
5.Good bulk stability.
