Product Description

Hard firebrick is a kind of alumina silicate brick containing 35-45%, and the refractories are SK 32-34. Brick is made of refractory clay, calcined limestone, mullite and other raw materials, with good wear resistance, peeling resistance, corrosion resistance. It has the characteristics of low porosity, high strength, heat peeling, wear resistance, creep resistance, etc., and is widely used in the lining of coke oven, glass kiln, cement rotary kiln, lime kiln, various incinerators and heating furnaces.
