Method for producing fused magnesia-aluminum spinel

Fused magnesia-alumina spinel is made of alumina powder and high-purity light-burned magnesia powder as the main raw materials, and is smelted at a high temperature above 2000°C in an electric arc furnace. The fused magnesia-aluminum spinel produced by our company has many grades, and can produce the products required by users according to the requirements of users.

Fused magnesia-aluminum spinel has the advantages of large bulk density, good thermal shock stability, strong erosion resistance and slag resistance. Calcined dolomite is widely used in steel refining, cement rotary kiln and glass industrial kiln. It is an ideal material for manufacturing continuous casting slides, nozzle bricks, ladle lining bricks and open hearth bricks. Bricks, refractory castables and basic raw materials for high and medium temperature kiln furniture bricks.
