Production process and characteristics
Using bauxite and charcoal (anthracite) as raw material, and fused under high temperature in electric arc furnace. The main chemical components are Al2O3, and TiO2. It also contains small amounts of SiO2 and Fe2O3, etc. The micro hardness 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 and hard bronze etc. Brown fused can also be used for making fine quality refractory etc. The refractoriness of high-alumina clinker is up to 1850℃.It has strong chemical stability and good physical properties.
