Corundum Brick Corundum brick introduction: Corundum brick uses high-quality corundum as main raw materials. In the making process, firstly we should deploy a scientific formula and add excellent performance additives, then the bricks will be moulded under high presure and sintered under high temperature, finally made the corundum refractory bricks . Advantages of corundum brick: Corundum brick can be divided into sintered corundum brick and fused corundum brick. refractory suppliers corundum brick has advantages of high strength, excellent wear resistance and strong anti-slag erosion, long service life and other characteristics. Corundum brick and chrome corundum brick, corundum mullite brick all can reduce the number of shutdown maintenance, thus saving maintenance costs, improve the furnace operating rate. Corundum brick uses: Corundum brick is a kind of high quality furnace lining materials and kiln materials for large blast furnace, rolling furnace and melting furnaces and k

Magnesia Brick The company uses high-grade magnesia and strict process to produce magnesium oxide content of more than 90%, with periclase crystalline phase mainly basic refractory material .   Magnesia brick has high refractoriness, good alkali resistance slag resistance, high load softening starting temperature, but poor thermal shock resistance. Sintered magnesia bricks to magnesia brick as raw material, crushing, ingredients, kneading, after molding at a high temperature 1550 ~ 1600 ℃ firing, high-purity products in firing temperature above 1750 ℃. Unfired magnesite bricks is added to the appropriate chemical binding agent in the magnesia by mixing, forming, drying made. Mainly used for steelmaking basic open hearth furnace bottom and the furnace wall, the permanent lining oxygen furnace, non-ferrous metal smelting furnace, high-temperature tunnel kiln, calcined magnesia refractory brick and cement rotary kiln lining, furnace and hearth furnace wall, glass furnace regene
