Introduction
Fused Al2O3-MgO Spinel is made from industrial alumina and high-purity CCM, melting in electric arc furnace. The resulting Fused Spinel has large crystals and exhibits excellent corrosion resistance to molten metals and slags, thermal shock resistance, and good hot strength.
It is an ideal material for production of high-grade magnesia-alumina brick, high performance magnesia-alumina castable, large cement kiln, magnesia-alumina ladle castable, blast furnace iron runner castable, slide gate nozzle, continuous casting slide board and nozzle brick.
