Fused Magnesia-alumina spinel(alumina rich) is smelted in the electric arc furnace at over 2000 ℃ high temperature, with the quality industrial alumina and high purity light burned magnesium as the raw materials.
It is characterized by large bulk density, good thermal stability, good slag resistance and thermal shock stability, strong resistance to erosion, corrosion and high temperature.
It is widely used in shaped and unshaped refractories, steel smelting, cement kilns, glass industrial kilns, etc.
