Application of Silica Refractory Brick
Silica fire brick are mainly used as refractory materials for protective wall of coking chamber and combustor in coke oven, regenerative chamber and slag pocket in steelmaking open-hearth furnace, soaking pit furnace and glass melting furnace, and other weight bearing area and top in ceramic firing kiln. Silicate bricks also can be used for the weight bearing area in high temperature and top of acid open hearth furnace.
