Description:
Brown aluminum oxide 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.
Refractory grade:
BROWN FUSED ALUMINA FRACTION | AL2O3 MIN | SIO2 MAX | TIO2 MAX | Fe2O3 MAX |
0-0.5mm | 94.50% | 0.80% | 2.23% | 0.35% |
0-1mm | 95.50% | 0.70% | 2.23% | 0.25% |
1-3mm | 95.75% | 0.66% | 2.18% | 0.23% |
3-5mm | 95.90% | 0.60% | 2.15% | 0.21% |
5-8mm | 96.00% | 0.50% | 2.10% | 0.18% |
Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening.
The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use. Dedicated lines produce products for different applications.
