Brown fused alumina has the characteristics of dense texture, high hardness, tan color, great toughness, and spherical grains, so what is brown fused alumina used for?Today I will introduce you to the uses of brown corundum.
Brown fused alumina is made of high-quality bauxite, iron filings, anthracite smelting at high temperature in the arc, crushed and shaped by a self-mill, magnetic separation to remove iron, sieved into a variety of particle sizes, the main chemical composition is Al2O3, its content is 94%-96%, and contains a small amount of Fe, Si, Ti, etc.
Uses of Brown Fused Alumina:
1. Sandblasting: As an environmentally friendly material, it has its place in the field of building materials or washed textiles.
2. Abrasives: Due to the superior performance of toughness and wear resistance, brown fused alumina can be used when grinding lenses and precision instruments, especially the grinding of industrial products such as TVs and mobile phones.
3. Coated abrasives: generally used for the production of brown corundum granular sand as a mold, the surface of the sandpaper and gauze products produced is more uniform and delicate.
4. It is one of the raw materials of refractory materials: refractory materials made of brown corundum will basically not have the problem of chalking and cracking.
5. In the field of precision casting: brown fused alumina granular sand is generally used in the processing of some steel products, mainly because its hardness and purity are very high, so it is suitable as a raw material for these products.
6. New filter material: It can be used as a metal or non-metal filter medium, and is reused in mineral processing, petroleum and other industries.
