Product description
Magnesia brick can be generally divided into sintered magnesia brick (also known as fired magnesia brick) and chemically combined magnesia brick (also known as non-fired magnesia brick) two categories. The magnesia brick with high purity and firing temperature is called directly bonded magnesia brick because of the direct contact of the magnesia grain. The brick made of fused magnesia is called fused fused magnesia brick.
Application of magnesia brick:
Magnesia brick are mainly used in steelmaking basic open hearth furnace, electric furnace bottom and furnace wall, oxygen converter permanent lining, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln lining, heating furnace bottom and furnace wall, glass kiln regenerator cell lattice brick, etc.
