Magnesia Brick is basic shaped refractory brick sintered from dead burned magnesia (DBM) raw material. It features high melting point and excellent resistance to alkaline slag.
Key Features：
- Extremely high melting point above 2800℃, excellent high-temperature strength.
- Superior alkaline slag corrosion resistance, ideal for basic furnace environment.
- Low hydration rate, good high-temperature volume stability.
- High bulk density and low porosity, strong wear resistance.
- Resistant to molten basic slag in steelmaking process.
Available Grades：
M-90: MgO ≥90%
M-92: MgO ≥92%
M-95: MgO ≥95%
M-97: MgO ≥97%
Main Applications：
- Steelmaking converter, electric arc furnace, ladle and refining furnace lining.
- Cement rotary kiln burning zone and lime kiln lining.
- Non-ferrous metal smelting furnaces with alkaline slag.
- Glass melting furnace regenerator.
