The brown corundum sold by our company is complete in grades and meshes. After many glass deep processing, photovoltaic companies, solar industry (polysilicon blasting, monocrystalline silicon blasting), hardware factory trials, the surface treatment effect is obvious, and the cost performance is high, welcome to consult!
Brown corundum, also known as corundum, is a brown artificial corundum produced by melting and reducing three kinds of raw materials such as alumina, carbon materials and iron filings in an electric furnace, so it is brown corundum.
The main chemical composition of brown corundum is AL2O3, whose content is 94.5% to 97%, and it also contains a small amount of Fe, Si, Ti and so on.
Brown corundum is one of the basic abrasives because of its high hardness and good toughness. Its main functions are as follows
(1) Due to high temperature resistance, corrosion resistance, high strength, etc., the sliding nozzle of pouring steel is used to treat the linings (walls and pipes) of rare metals, special alloys, ceramics, and ironmaking blast furnaces; physical and chemical utensils, spark plugs, Heat and oxidation resistant coating.
(2) Due to the characteristics of high hardness, good abrasion resistance and high strength, it is used as a component of various reaction vessels and pipes and chemical pumps in chemical systems; it is used for mechanical parts and various molds, such as wire drawing molds, Squeeze the tip of a pencil core, etc .; make knives, mold abrasives, bulletproof materials, human joints, sealing mold rings, etc.
(3) Corundum insulation materials, such as corundum light bricks, corundum hollow balls 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.
Brown corundum grain sand is processed by manual screening of brown corundum blocks, using rollers, ball mills, Barmac and other equipment. The grain size is F8-F325. It is mainly used for polishing, grinding, industrial grinding, etc., and can also be performed according to customer requirements. Processing by water washing, pickling and other methods can meet the different needs of customers.
