Description
Mullite Refractory Brick is a high-aluminum refractory material with mullite (3A203-2si02) as the main crystal phase. The content of aluminum oxide is between 65%and 75%. It can be used directly for high -temperature kiln lining. It is currently widely used in the lining of shuttle kiln, mixed road kiln, glass and petrochemical kiln. The volume density indicator of mullite refractory brick is a comprehensive reflection of the volume and mineral composition of mullite bricks. Because it is easier to determine, it is usually used as a method for judging the degree of sintering of mullite stone bricks. The factors that affect the volume density of mullite stone fire -resistant bricks are the following two aspects: First, the volume density of the alumina content of the mullite refractory brick and the size of the alumina particles, on the other hand, the control of the production process process.
Features
Low thermal conductivity / Good insulation effect / Nice Energy -saving effect / High fire resistance
Application
Mullite Refractory Brick is suitable to construcation of superstructures and crowns of glass fiber furnace and glass furnace, borosilicate and sodium silicate glass tanks.
Mullite refractory brick finds a wide range of applications, including:
Kilns and Furnaces: It is used in various types of kilns, including tunnel kilns, shuttle kilns, and rotary kilns, as well as in high-temperature furnaces for ceramics, glass, and metals production.
Steel and Iron Industry: Mullite brick is employed in steelmaking processes, such as steel ladles, tundishes, and continuous casting systems, where high temperature and chemical resistance are required.
Petrochemical Industry: It is used in the linings of reactors, incinerators, and combustion chambers where high-temperature and corrosive conditions are present.
Glass Industry: Mullite fire brick finds applications in glass melting furnaces, regenerators, and checkers, where it provides excellent resistance to thermal shock and chemical attack.
Ceramic Industry: It is used in ceramic kilns and furnaces for firing and sintering processes, where it maintains dimensional stability and resistance to thermal cycling.
