Magnesium Brick

The raw material of magnesia brick is mainly magnesite, and its basic component is MgCO3. After high temperature calcination, it is crushed to a certain particle size to become sintered magnesia. Magnesia is widely used as a material for repairing furnaces, beating materials, and magnesia containing less impurities (ω(CaO)<2.5%, ω(SiO2)<3.5%) as a raw material for the production of magnesia bricks.

Magnesium brick is made from periclasite with alkaline refractory products as raw material, it has good refractoriness performance, good refractory under load and high temperature machinery strength and corrosion resistance. It can be applied in metallurgy (EAF, Converter, Mixer furnace), non –ferrous (Smelting furnace) industries and high temperature tunnel kiln, sintered magnesite kiln, cement rotary kiln, glass kilns, new type lime kiln, soaking furnace, heating furnace, etc.
