1. What is zirconium corundum
Zirconium corundum is a type of corundum. It is smelted in an electric arc furnace at temperatures above 2000°C using alumina and zirconium oxide as raw materials. The artificial corundum produced can be divided into three types: low zirconium corundum, medium zirconium corundum and high zirconium corundum according to different zirconium oxide content.
Zirconium corundum has a tough texture, dense structure, high strength, good thermal shock resistance, and good melt erosion resistance. It can be used as an abrasive and generally belongs to the category of high-grade abrasives.
2. What is the grinding ability of zirconium corundum abrasive?
Zirconium corundum abrasive is a high-performance abrasive material with excellent grinding ability. , it has high hardness and good wear resistance, and can efficiently grind various materials. It is especially suitable for precision processing of high-hardness and high-strength materials. The grinding ability of zirconium corundum abrasives is mainly reflected in the following three aspects. :
1. Strong ability to grind materials with high hardness
Zirconium corundum abrasive has high hardness and can efficiently grind materials with high hardness. . For example, zirconium corundum abrasives can achieve efficient grinding of high-hardness ceramic materials, metal materials, glass and other materials.
2. Strong grinding ability for precision machining
The particle size of zirconium corundum abrasive is uniform, which can better control the size and shape of abrasive particles during the grinding process. This results in a more refined grinding effect. Therefore, zirconium corundum abrasives are widely used in the field of high-precision processing of precision devices, optical components, etc.
3. It has good self-sharpening and self-grinding properties
Zirconium corundum abrasive has good self-sharpening and self-grinding properties and can stay sharp The cutting edge can automatically remove the grinding debris on the surface during the grinding process, reducing the accumulation of cutting heat, thereby reducing friction and thermal stress during grinding, and improving cutting efficiency and accuracy.
3. What are the disadvantages of zirconium corundum abrasives
Zirconium corundum is used as an abrasive, and its grinding performance is very good, but it also has certain disadvantages Disadvantages:
1. Poor thermal conductivity
Zirconium corundum abrasive has poor thermal conductivity and easily generates excessive heat during high-temperature cutting and polishing processes. May cause problems such as thermal cracks and surface deformation.
2. High difficulty in preparation
Due toZirconium corundum abrasives have a high melting point and difficulty in preparation, making their production process relatively complex and expensive, which also limits the wide application of zirconium corundum abrasives.
