It is mainly used for the partition walls of the carbonization chamber and combustion chamber of coke ovens, the regenerators and slag chambers of steel-making open-hearth furnaces, soaking furnaces, refractory materials of glass melting furnaces and ceramic firing kilns, and other kiln vaults. Load-bearing parts. It is also used in high-temperature load-bearing parts of hot blast furnaces and acidic open-hearth furnace tops.
