Fire Clay Brick/Refractory Brick
1)Fire Clay Brick made of adopt ultra low cement hardening process,
and own even inner structure,
hence the material for tank bottom and wall of glass melting tank .
2)Fire Clay Brick are widely applied in coke oven, blast furnance, air stove, molten steel ladel, gating system, boiler, cement kiln, glass kiln, kinds of kiln lining and thermal equipment.
