Brown corundum is Using bauxite and charcoal (anthracite) as raw material and fused under high temperature in an electric arc furnace. The main chemical components are Al2O3 and TiO2. It also contains small amounts of SiO2 and Fe2O3, etc. The microhardness is 1800-2200kg/mm2. The toughness is higher than Silicon Carbide. The abrasive tools made by brown fused alumina are suitable for grinding carbon steel, normal alloy steel, malleable cast iron, hard bronze, etc. Brown fused can also make fine quality refractory, etc. The refractoriness of high-alumina clinker is up to 1850ºC. It has strong chemical stability and good physical properties.
Brown Fused Alumina For Refractory Advantages:
1) No burst,no pulverization and crack in the using course of refractory
2) Refractory temperature is more than 1900°C
3) High quality bauxite as raw material
4) Low coefficient of linear expansion
5) Very low amount of iron oxide
6) High purity
Brown Corundum For Abrasive Sandblasting Precision Casting Advantages:
1) Very low amount of iron oxide, suitable for non-ferrous blasting operations.
2) Not affecting the color of the processing cases.
3) Sandblasting in the non-iron process.
4) High speed processing.
