How is brown corundum made? What are the functions of brown corundum?
Brown corundum is a new polishing material commonly used in our industrial production, but many friends do not know where brown corundum can also be used?
Brown corundum is the use of bauxite, carbon materials, iron chips three raw materials in the electric furnace melting reduction and made of brown artificial corundum, brown corundum abrasive, good wear resistance, good hardness, production of a grade, two, brown corundum common name also known as emery. The chemical composition is AL2O3, its content is 94.5%-97%, and contains a small amount of Fe, Si, Ti and so on. Through the practice of dozens of refractory production enterprises, the product has the characteristics of no initiation, no pulverization and no cracking in the application process. In particular, its cost performance is much higher than that of traditional products, which makes it a good aggregate and filler for better refractories.
Brown corundum is tan, of which the third grade brown corundum is commonly known as black corundum color is dark. It has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. The main component of the product is alumina, and the classification is differentiated by aluminum content, and the lower the aluminum content, the lower the hardness; The product particle size is produced according to international standards and national standards, and can be processed according to user requirements. The general particle size is F4 -- F320, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact resistant, because of the crushing process with the automill, the particles are mostly spherical particles, the surface is dry and clean, and it is easy to combine with the binder.
Large use of brown corundum: workpiece material, sand blasting purpose process requirements. Stainless steel, surface decontamination, welding slag removal and matte effect. Iron workpiece, rust, dirt, oxide removal, increase the coating, coating adhesion. Aluminum workpiece, skin removal, surface strengthening, finishing action.
Brown corundum is known as the teeth of industry: mainly used in refractory materials, grinding wheels, sandblasting. Widely used in aluminum profile, copper profile glass, washed jeans precision mold and other fields; It is a grinding grade abrasive, used in many fields of free grinding, is widely used in the domestic advanced grinding material; It is the raw material of sandpaper, gauze and other manufacturers; At the same time, it is also mainly used for automotive braking parts, special tires, special construction products, etc. It can be used as a wear-resistant material for building highway pavement, airstrip, dock, parking lot, industrial floor, sports field and so on.
