Bulk calcined aluminum oxide for abrasives applications

calcined aluminum oxide/brown fused alumina

1. Specifications

.Al2O3 :80-85%. 

SiO2:8%

Fe:4-5%

TiO2:4%

2. Description

Brown aluminum oxuide is electrically fused in an arc furnace from a mixture of bauxite at high temperature. It has brown color, high hardness and great toughness. The abrasive tools made of brown aluminum oxide are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze.It used for refractory aluminum oxide lining mixture, pouring materials castable,etc.

P Series: P16-P2500, 27 Grit Numbers

F Series: P14-P1200, 30 Grit Numbers

3.Advantages

1). Corrosion resistance, high strength, high hardness. 

2). Good wear-resisting performance,resist to shock. 

3). It is a cost-effective substitute for Ferrosilicon. 

4).It costs less than ferrosilicon and carbon combination. 

5). It has no dust nuisance while feeding the material. 

4. Applications

The abrasive tools made from brown fused alumina is  applicable to non-ferrous materials with tensile strength, such as nonferrous metals, wood, leather, plastic, rubber, stone material, gray

cast iron, silicate material (glass, ceramic, concrete and refractory matter), etc. Adding a proper amount of black

silicon carbide as deoxidant during the smelting of steels can significantly improve the quality of  steels. Due to its heat resistance, resistance to chemical attack and thermal shock resistance, it is widely used in high quality

refractory matter and other industries.
