Fused Spinel

Sizes Available:
0-1mm, 1-3mm, 3-5mm, 100mesh,
200mesh, 325mesh
Other sizes are also available on request.

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.
It is used in the production of refractory materials used for the sinter and transit zones of rotary furnaces in cement industry, for the arches of electric arc-furnaces, for the refractory lining of high-frequency furnaces, and various kinds of torpedo ladles and other ladles used in steel industry.
