Alumina-silica brick is a common refractory material with important applications in many high-temperature industrial fields.
In the metallurgical industry, alumina-silica brick is often used for the lining of steelmaking converters. It can withstand the high temperature generated during the converter steelmaking process as well as the scouring and erosion of molten steel and slag, ensure the safe operation of the converter, extend the service life of the converter, and reduce production costs. At the same time, alumina-silica bricks also play an important role in the middle and lower parts of the furnace body of the ironmaking blast furnace, which can resist the wear of high-temperature coal gas and furnace materials and maintain the normal production of the blast furnace.
In the cement kiln of the building materials industry, alumina-silica bricks are the key lining materials. Especially in the firing zone of the cement kiln, where the temperature is extremely high, alumina-silica bricks can work stably with their excellent high temperature resistance and thermal shock resistance, reduce the number of kiln shutdowns and maintenance caused by material damage, and improve the efficiency and quality of cement production. In glass kilns, alumina-silica bricks can be used in parts such as the kiln roof and breast wall, and can withstand the high temperature radiation and erosion of glass liquid during the glass melting process, providing a guarantee for the stable production of glass.
In the boilers of the power industry, alumina-silica bricks are often used for the lining of the furnace. It can withstand the high temperature generated by coal combustion, protect the metal structure of the boiler, reduce heat loss, and improve the thermal efficiency of the boiler. In addition, alumina-silica bricks are also widely used in some industrial furnaces such as forging heating furnaces and heat treatment furnaces, providing a reliable high-temperature environment for various industrial production processes.
