Description

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

 

Applicatior

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, siding nozzle, Iining brick for lade, side plate for continues casing, nozzle block and roof brick for open hearth furnace, which can improve the thermal shock resistance. It is the ideal material to replace magnesia-chrome refractories.
