Description of Magnesia-spinel brick:
Abrasive resistant Magnesium Alumina Spinel Refractory Brick For Rotary Kiln shuttle kiln
Magnesia-spinel brick are a high-performance alkaline refractory material widely used in high-temperature industrial environments, such as cement rotary kilns, non-ferrous metallurgy, lime kilns, glass industry and other fields that need to withstand extreme temperatures and chemical erosion. Here are some key features and introduction of Magnesia-spinel brick:
Main Components of Magnesia-spinel brick
Abrasive resistant Magnesium Alumina Spinel Refractory Brick For
Rotary Kiln shuttle kiln
Periclite (MgO): Provides the basic framework and high temperature
resistance of the brick body.
Magnesium Aluminate Spinel (MgAl2O4): Is a stable solid solution
that improves the brick's resistance to chemical attack and thermal
shock stability.
