Now alundum is used more and more in our life, such as brown corundum, white corundum, fused white corundum, and black corundum. Although they are abrasives, do you know the characteristics of these abrasives? Today, the manufacturer of Corundum Abrasive will tell you about the use of corundum.
Corundum takes industrial alumina powder as raw material, melts in a high-temperature electric arc above 2000 degrees, and then cools to obtain white corundum; Pulverizing white corundum, forming, magnetically separating to remove iron, and sieving to obtain various particle sizes; White corundum has compact texture, high hardness, and sharp edges.
1. What are the important physical properties of corundum
Corundum has good thermal stability, high temperature resistance above 1750 degrees, high purity, good self-sharpening, strong grinding ability, low heat value, high efficiency, acid and alkali corrosion resistance, but slightly lower toughness.
2. What are the industrial uses of corundum
It can be used as wet sand or dry sand or jet sand, fixed abrasive tools and coated abrasive tools. It is also of great significance for ultra-fine grinding and polishing in crystal and electronic industries and for manufacturing high grade refractory. It can be used as contact medium, insulator and precision casting sand, etc.
3. Scope of application of corundum
It is also suitable for work hardening steel, alloy steel, high speed steel, high carbon steel and other materials with higher hardness and tensile strength.
