Fused alumina-maganesia spinel

Fused Magnesia-Alumina Spinel is produced by melting high purity alumina and magnesia together, in the proper ratios, in electric arc furnaces. The resulting Fused Spinel has very large crystals and exhibits excellent corrosion resistance to molten metals and slags, thermal shock resistance, and good hot strength.

Fused Magnesia - Alumina Spinels uses

Fused Magnesia - Alumina Spinels are used mainly for refractory applications: It is widely used to make high performance refractory castable,slide gate nozzle,ladle brick roof of steel making electric furnace,converter,ladle,transitional zone of large cement rotary kiln,regenerative chamber of glass kiln.
