Product description:
Fused magnesia-alumina spinel, using high purity light-burnt magnesia and high quality aluminium oxide 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 corrosion resistance. 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 furnace,which can improve the thermal shock resistance.
