95 content level of brown fused alumina
Product introduction
Brown corundum the introduction of brown fused alumina is bauxite, coke (anthracite) as the main raw material, high temperature smelting in arc furnace neijing and become, the main chemical composition for AL2O3, TiO2 ring contains a small amount of SiO2 and Fe2O3, microhardness HV1800-2200, toughness than SiC high, use it made of grinding tool, suitable for grinding tensile higher metal, such as all kinds of general steel, malleable cast iron, 95 content level of brown fused alumina ,hard bronze, etc., can also make advanced refractory material. To edit this period of brown corundum performance properties: crystal shape trigonal system chemical properties: gender and acid reaction: in aqua regia and hydrofluoric acid corrosion and slightly in alkali reaction: only and alkali solution heat slightly reaction oxidation reduction effect: no density: 3.90 g/cm3 hardness: knoop spectrum hardness 2000-2200 Kg/best callus induction, Morse hardness 9.0 color: dark brown, after calcining color showed deep blue melting point: 2250 C highest using temperature: 1900 C heat: (Cal/g. C) 0.26 (20-90 - C) coefficient of thermal conductivity at room temperature 900 C (Cal/cm3. SEC. C) refractive index: e = 1.760 w = 1.768 (Na line) resistivity: 30 C 300 C 900 C 1600 C (cm) 10 16 10 13 10 5 10 4 coefficient of linear expansion: 7-9 (0-1600 - C) to edit this period of brown corundum grade brown corundum principal component is alumina, grade will use aluminum content to distinguish, the lower the aluminum content is lower hardness. The granularity of product according to the international standards and national standards production, can be in accordance with the requirements of customers processing size. Universal size number is the F4 ~ F320, its chemical composition depending on the particle size and different. Outstanding characteristic is crystal size small impact resistance, because use since the mill processing broken, grain much for spherical particles, the surface dry clean, easy to bond combination. Edit this section brown corundum use range brown corundum called industrial teeth: mainly used in refractory materials, grinding wheel, sand. 1. The sand brown corundum - sandblasting abrasive hardness modest, stacking density high, no free silica, more than major, good toughness, Mr Kay brown fused alumina is an ideal "environmental protection" type sand materials, widely used in aluminum, copper material glass, washing jeans precision mould, etc; 2. Free grinding, grinding grade abrasive, applied in tube, optical glass, monocrystalline silicon, glasses, watches and clocks, glass, crystal glass, jade and other areas of free grinding, is the widely adopted advanced grinding materials; 3. Resin abrasive, abrasive has the color appropriate, hardness, toughness, suitable particle section type and cutting edge keep degrees, applied in resin grinding tool, the effect principleWant to; 4. Coat with abrasive, abrasive is abrasive paper, cotton and other production manufacturer production raw material; 5. Brown corundum functional filler - mainly used in automobile brake parts, special tires, special building products brought can be used as, build up the highway pavement, runway, docks, car parks, industrial floor, sports venues and wear resistant materials; 6. Filtration medium - is abrasive new application field, the granular abrasive make filtering bed bottom medium, purify drinking water or wastewater at home and abroad, because of the new water filtration material, especially suitable for non-ferrous metal processing, oil drilling mud weighting agent: 7. Abrasive hydraulic cutting - is abrasive for cutting medium, rely on high pressure water jet in basic cutting, applied in the oil (gas) pipe, steel etc cutting, is a new type, environmental protection, safe way to cut. Customer: washing factory cowboy sand workshop shipyard shipyard steel structure factory micro powder factory for our abrasive paper, ShaBuChang crystal glass industry building floor industry steel hardware industry electronics industry qi car manufacturing coast terminals, 95 content level of brown fused alumina ,parking lot hospital stadium. Sand industry cooperation content to all types of users required floor aggregate and abrasive. The product is reliable, stable performance, excellent quality, easy to use. Level 1 brown corundum hd picturesTo edit this period of its main function (1) with high temperature resistance, corrosion resistance, high strength, such as performance, so use pouring steel slide gate, smelting rare metals, special alloy, ceramics, puddling blast furnace lining (wall and pipe); Physical and chemical vessels, spark plug, heat resisting oxidation coating. (2) with hardness, good abrasion resistance, high strength characteristics and the chemical industry system, used for all kinds of reaction vessel and pipe, chemical pump parts; Do mechanical parts, all kinds of mold, such as wire drawing die, crowded pencil refill die nozzle, etc.; Do tool, mould abrasive, bulletproof material, human body joints, seal die ring, etc. (3) corundum thermal insulation material, such as corundum light brick, alumina hollow ball and fibre products, which are widely used in all kinds of high temperature furnaces of furnace wall and roof, already high temperature resistant and heat preservation. Brown fused alumina particle size sand is by artificial selection brown corundum block, adopts the roll, ball mill, and mark equipment processing and become, particle size by F8 - F325. Mainly used for polishing, grinding, industrial grinding, etc., can also according to customer requirements for washing, pickling treatment method processing, can meet the different needs of customers. Low carbon brown corundum after bath and special process of reprocessing, reduce brown corundum of residual carbon content, and make product in use not pulverization, not burst and great toughness is abrasives industry, 95 content level of brown fused alumina ,the first choice of refractory industry raw materials. Mainly used in ceramic grinding tool, high-grade grinding tool, organic abrasive, abrasive belt, coated with grinding tool, etc., according to the residual carbon content is divided into: calcined brown corundum C or less 0.05%, low carbon brown corundum C or less 0.10%, common brown corundum C or less 0.15%.
