Fused Magnesium Aluminum Spinel is a new type of high-purity synthetic refractory raw material, which takes high-quality aluminum oxide powder and high-purity light burned magnesium powder as the main raw materials .It is made by melting at a high temperature above 2000 ℃ and cooling in an electric arc furnace. It has the characteristics of large bulk density, low water absorption, high temperature resistance, small thermal expansion coefficient, good thermal stability, good appearance color, slag resistance and strong corrosion resistance. Fused Magnesium Aluminum Spinel is widely used in refractories, steel smelting, cement rotary kilns and glass industrial kilns. It is an ideal raw material for the production of high-performance castables, sliding nozzles, ladle lining bricks and other refractory materials and investment casting.
