zirconium corundum material for glass melting furnaces

Zirconium corundum is made by using alumina and zirconia as raw materials in an electric arc furnace at a high temperature of 2000 ° C or higher. According to the content of ZrO2, there are generally 25 zirconium corundum (ZrO2 25%) and 40 zirconium corundum (ZrO2 40%). The texture is tough, the structure is dense, the strength is high, the thermal shock is good, and it is generally grayish brown. Zirconium corundum has good melt erosion resistance. As a kind of advanced abrasive, it can manufacture high-performance heavy-duty grinding wheel, which has good grinding effect on steel, cast iron, heat-resistant steel and various alloy materials. Zirconium corundum is also an advanced refractory raw material. It is an ideal material for making high-performance sliding nozzles and immersion nozzles. It can also be used to make zirconium corundum bricks for glass melting furnaces.
