Brown corundum has high fire resistance and abrasion resistance
Brown corundum is generally used for making aggregates and fine powders in refractory materials. Its advantages are high fire resistance, wear resistance, erosion resistance, erosion resistance, large bulk density, and high alumina content. It is mainly used in high aluminum and Alumina based. There are also high load softening temperature and high temperature volume stability when making products. However, the impurities of brown corundum determine the life of the product during use. Because the impurities have not been completely removed during smelting, brown corundum also contains secondary crystal phases such as calcium hexaaluminate, anorthite, spinel, rutile, and glass phases, iron alloys, and solid solutions. In a great sense, the smelting process and smelting time of brown corundum determines its product performance and quality.
With the development of society and the improvement of grinding technology, people's requirements for grinding tools have become more and more precise, and the pertinence of grinding tools has become higher and higher, so more new types of artificial abrasives have been developed. Brown corundum coated abrasive is a low cost method and process that can effectively improve the various properties of the abrasive. Brown corundum high-temperature coated abrasives are widely used in the manufacture of coated abrasives and resin-consolidated abrasives.
