Scope of application of brown corundum: 1. Sandblasting-"OK Okay" abrasive has moderate hardness, high bulk density, no free silica, high specific gravity and good toughness. It is an ideal "environmental protection" sandblasting material, which is widely used in aluminum profile, copper profile glass, precision mould for washed jeans and other fields. 2. Free grinding-"OK Okay" abrasive is used for free grinding in CRT, optical glass, monocrystalline silicon, lens, watch glass, crystal glass, jade and other fields. It is an advanced grinding material widely used in China. 3. Resin abrasive-"OK OK OK" abrasive has proper color, good hardness and toughness, suitable particle cross-section type and blade retention, and it is applied to resin abrasive with ideal effect; 4. Coated abrasives-"OK Okay" abrasives are raw materials for manufacturers such as sandpaper and gauze; 5. Functional fillers-mainly used for automobile brakes, special tires, special building products, etc. It can be used as a wear-resistant material for building roads, airstrips, docks, parking lots, industrial floors, stadiums, etc. in expressway. 6. Filter media-a new application field of "good good" abrasive. Granular abrasive is used as the bottom medium of filter bed to purify drinking water or wastewater. It is a new water filtration material at home and abroad, especially suitable for mineral processing of non-ferrous metals. Weighting agent for oil drilling mud: 7. Hydraulic cutting-based on ok Okay abrasive, high-pressure hydraulic jet is used for basic cutting, which is applied to oil (natural gas) pipelines, steel and other parts. Washing factory cowboy sandblasting workshop shipyard steel structure factory micropowder factory grinding wheel factory sandpaper. Emery cloth factory crystal glass industry building floor industry steel industry hardware industry electronics industry automobile manufacturing coastal wharf, parking lot hospital stadium, sand blasting industry and other cooperation to meet the needs of various users for floor aggregate and abrasive. Brief introduction of brown corundum with reliable product, stable performance, excellent quality and convenient use
Brown corundum is made of high-quality bauxite, anthracite and iron filings, which are smelted in an electric arc at a temperature above 2000 degrees. It is crushed and shaped by a autogenous mill, and iron is removed by magnetic separation and screened into various particle sizes. Its texture is compact, its hardness is high, and its particles are spherical. Suitable for manufacturing ceramics, resin high consolidation abrasives, grinding, polishing, sandblasting, precision casting, etc. It can also be used to manufacture advanced refractories. . Grade of brown corundum The main component of brown corundum is alumina, and the grade is also distinguished by aluminum content. The lower the content of of ok aluminum, the lower the hardness.

Its main functions
(1) Because of its high temperature resistance, corrosion resistance and high strength, slide gate is used for smelting rare and precious metals, special alloys, ceramics and lining (walls and pipes) of ironmaking blast furnaces; Physical and chemical ware, spark plug, heat-resistant and oxidation-resistant coating.
(2) Because of its high hardness, good wear resistance and high strength, it is used as a component of various reaction vessels, pipelines and chemical pumps in the chemical system; Making mechanical parts, various dies, such as wire drawing die, extruding pencil lead die, etc. Making tools, mold abrasives, bulletproof materials, human joints, sealing mold rings, etc.
(3) corundum thermal insulation materials, such as corundum lightweight bricks, corundum hollow balls, fiber products, etc., are widely used in the furnace walls and tops of various high-temperature furnaces, which are both heat-resistant and heat-insulating. Brown corundum particle size sand is made by manually selecting brown corundum blocks and processing them with roller pair, ball milling and Bamak equipment. The particle size is F8 F325. It is mainly used for polishing, grinding and industrial grinding, and can also be processed by washing and pickling according to customer requirements, which can meet different requirements of customers.
After pre-treatment and special process, the low-carbon brown corundum reduces the residual carbon content in brown corundum, making the product not powdery, explosive and tough in use. It is the preferred raw material for abrasive and abrasive industry and refractory industry. Mainly used in ceramic abrasives, high-grade abrasives, organic abrasives, abrasive belts, coated abrasives and so on. According to the carbon residue content, it is divided into: calcined brown corundum C ≤0.05%, low-carbon brown corundum C ≤0. 10%, and ordinary brown corundum C ≤0. 15%.
