Fused magnesia-alumina spinel, using high purity light-burnt magnesia and high quality aluminiumoxido as main raw materials, fusing in electric arc furnace and cooled, is a new kind of high purity synthesized refractory raw material.

Fused magnesia-alumina spinel is characterized by high bulk density, good thermal shock resistance and corrosionresistance. It is mainly used to produce high grade magnesia-alumina brick, high performance magnesia-alumina castables, sliding nozzle, lining brick for ladle, slide plate for continues casting, nozzle block and roof brick for open hearth furace, which can improve the thermal shock resistance. It is the ideal material to replace magnesia-chrome refractories.
