Brown Corundum
Brown corundum is a high-grade synthetic raw material, which is made of high-quality bauxite as the main raw material, adding coke, iron filings and other auxiliary materials, and smelting and purifying at high temperature in an electric arc furnace. Brown corundum is generally brown in color, and its mineral composition is mainly α-Al2O3. Its advantages are:
1. High refractoriness
2. High alumina content
3. Wear resistance and corrosion resistance, etc.
Product Description
Brown fused alumina blocks are mainly made of bauxite, carbon, and iron filings through high-temperature electric arc melting, and the quality of the selected materials largely determines its quality. Generally used bauxite alumina content must meet the standard, even higher than the actual standard. At the same time, in the production process, it is necessary to strictly follow the production process to minimize the impact of impurities on the product.
Application
Due to its high temperature resistance, corrosion resistance, high strength and other properties, the steel sliding nozzle is used to smelt rare and precious metals, special alloys, ceramics, lining (walls and pipes) of ironmaking blast furnaces; physical and chemical vessels, spark plugs, heat-resistant and anti-oxidation coating.
Due to its excellent high temperature stability and wear resistance, it is often used in the chemical industry for high temperature piping, kiln and burner linings. It can withstand thermal stress and thermal shock at high temperatures while protecting pipes and kilns from corrosion and wear.
Corundum thermal insulation materials, such as corundum lightweight bricks, corundum hollow spheres and fiber products, are widely used in furnace walls and roofs of various high-temperature furnaces, which are both high temperature resistant and thermally insulating.
