Product detail
High Quality Silica Brick
High-quality silica bricks are mainly used for the partition walls of carbonization chambers and combustion chambers of coke ovens, regenerators and slag chambers of steel-making open-hearth furnaces, soaking furnaces, refractory materials of glass melting furnaces, and ceramic firing kilns. The roof and other load-bearing parts are also used for the high-temperature load-bearing parts of hot blast stoves and the roof of acid open hearth furnaces.
