Fused Magnesia-Alumina Spinel:
- Fused magnesia-alumina spinel, using alumina and high purity light-burnt magnesia as main starting materials, fusing in electric arc furnace and cooled
- Fused magnesia-alumina spinel is a new kind of purity synthesized refractory raw material.
- Fused magnesia-alumina spinel is characterized by high bulk density, good thermal shock resistance and corrosion resistance.
- Fused magnesia-alumina spinel is testified that, addition of fused magnesia-alumina spinel can improve the slag resistance and thermal shock resistance of refractory products, fabricated parts and monolithic refractories.
- The Fused 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.
