high alumina refractory

,

high temperature refractory

Alumina-magnesium spinel ladle ramming mass good slag resistance high temperature strength

Because the magnesia-alumina spinel with the characters of strong resistance to slag erosion, excellent thermal shock resistance and high temperature strength, it is more and more used as steel-making refractory material.

 

Alumina-magnesium spinel ramming mass refractory used in the ladle is made of superior bauxite, high quality synthetic spinel, additive and binding agent, it is with excellent slag corrosion resistance, high temperature resistance, good thermal shock resistance performance, also with long service time, safe and stable advantages, which is the ideal ladle lining material, it can be directly poured into lining and can be made into precast blocks.
