Product Specifications
ZA40,ZA25
Scope of application
It is a refractory material in the steel industry and other industries. It is widely used in the production and manufacturing of refractory materials such as continuous rolling and casting, nozzles, runners, glass furnaces, etc. in the steel industry.
Products Description
Zirconia corundum is made of aluminum and zirconium as the main raw materials, smelted at 2250℃, sintered by special processing technology and Barmack. It has excellent quality and extremely hard and dense structure. It is a refractory material for the steel industry and other industries. According to the ZrO 2 content, zirconium corundum generally includes low zirconium corundum (ZrO 2 10%~15%), medium zirconium corundum (ZrO 2 25%) and high zirconium corundum (ZrO 2 40%).
Application scope
It is widely used in the production and manufacturing of refractory materials such as continuous rolling and casting, nozzles, runners, glass furnaces, etc. in the steel industry. Zirconium corundum has good resistance to melt erosion. As a high-grade abrasive, it can make high-performance heavy-duty grinding wheels and has a good grinding effect on steel parts, cast iron parts, heat-resistant steel, and various alloy materials; in addition, Zirconium corundum is also a high-grade refractory raw material. It is an ideal material for making high-performance sliding nozzles and immersed nozzles. It can also be used to make zirconium corundum bricks for glass melting furnaces.
Production Process
Zirconium corundum is mainly made of aluminum and zirconium materials. It is smelted at a high temperature of 2250°C and formed by Barmac using special processing techniques.
