Zirconium corundum is smelted at high temperature in an electric arc furnace with zircon sand as the main raw material. It has tough texture, compact structure, high strength and good thermal shock. As an abrasive, it can manufacture high-performance heavy-duty grinding wheels, which have a good grinding effect on steel parts, iron castings, heat-resistant steels, and various alloy materials; in addition, zirconium corundum is also a refractory raw material. It is an ideal material for high-performance sliding nozzles and immersion nozzles. It can also be used to make zirconium corundum bricks for glass melting furnaces.
