Introduction:
Magnesia bricks are alkali-resistant materials with good fire resistance and corrosion resistance, and strong resistance to alkali slag. The refractoriness of magnesia brick is above 2000℃. Magnesia bricks are widely used in inspection rooms of glass jars, lime kilns, non-ferrous metallurgical furnaces, open-air furnaces, iron stirrers and electric arc furnaces.
 
Features:
1.High refractoriness, usually refractoriness above 2000℃.
2. High refractoriness under load.
3. Excellent slag wear resistance and higher bulk density.
4. Lower apparent porosity and lower impurity content.
 
Application:
Magnesia Brick is mainly used for furnace lining, furnace bottom and furnace wall, oxygen converter permanent lining, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia and cement rotary kiln lining, furnace bottom and furnace wall, glass furnace regenerative lattice Bricks, etc.
