Zirconium corundum based on alumina, zirconia
as raw material to above 2000 ℃ high temperature hitches in electric arc
furnace smelting.Zirconium corundum tough texture, compact structure, high
strength, good thermal stability, generally gray brown.The main mineral phases
of zirconium corundum are eutectic formed by a-Al2O3 and Al2O3-ZrO2.General
zirconium corundum 25 (ZrO2 25%) and zirconium corundum 40 (ZrO2 40%),
depending on the ZrO2 content.

Usage
Widely used in the
steel industry continuous rolling continuous casting, shuikou, runner, glass
kiln and other refractory materials manufacturing.Zirconium corundum has good
resistance to melt erosion. As a kind of advanced abrasive, it can produce high
performance heavy load grinding wheel and has good grinding effect on steel,
cast iron, heat-resistant steel and various alloy materials.In addition,
zirconium corundum is a kind of high grade refractory material, which is an
ideal material for making sliding nozzle and immersion nozzle with high
performance, and also can be used for making zirconium corundum brick for glass
melting furnace.
