Description of Directly bonded Magnesite chrome bricks
Direct Bond/Semi-Rebonded/Rebonded Magnesia Chrome Bricks for Semiting Copper/Aluminum/Lead/Platium
Magnesia Alumina Spinel Refractory 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 Directly bonded Magnesite chrome bricks
Main Components of Magnesia Alumina Spinel Refractory Brick
Direct Bond/Semi-Rebonded/Rebonded Magnesia Chrome Bricks for Semiting Copper/Aluminum/Lead/Platium
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.
