Product detail
Magnesia Brick
Main Composition:MgO
Application:Various kinds of industrial kiln
Capacity:1000 tons per month
Color:Yellow
Size:As your requirements
Product 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.
