Fused Spinel
Fused Magnesia-Alumina Spinel is produced by melting high purity alumina and magnesia together, with the proper ratios, in electric are furnaces. Magnochrom Fused Spinel has very large crystals and exhibits excellent corrosion resistance, thermal shock resistance, and good hot strength to molten metals and slags.
Fused Spinel is mainly used to produce high grade magnesia-alumina bricks, magnesia-alumina castable, continuous casting skateboards, nozzle blocks and roof bricks, ladle lining bricks and flat furnace bricks, as well as large-scale cement basic raw materials for kilns, transition zone lining bricks of medium-sized cement kilns, refractory castable and high and medium temperature kiln furniture bricks.
It is widely used in steel smelting, electric furnace roof, ladle, cement rotary kiln, glass industrial furnace and metallurgical industry, etc.
