The common name for a brown fused alumina is also called the emery, are made of alumina, carbon materials, scrap iron three kinds of raw materials in the electric furnace melting reduction brown alundum, made by reason of brown fused alumina. Brown fused alumina is mainly chemical composition is AL2O3, and its content in 94.5% 94.5%, the other contains a small amount of Fe, Si, Ti, etc. Brown fused alumina is mainly divided into three, brown fused alumina is one of the best level, followed by secondary and tertiary, and the quality standards of brown fused alumina is mainly to see the content of AL2O3 and content in more than 95% for brown fused alumina, which is often said 95 brown fused alumina. Secondary corundum and tertiary corundum content drops, quality also decreases. Brown fused alumina colour can see colors to distinguish, because of the brown fused alumina containing Fe elements (iron), Fe element is red-brown, so brown fused alumina appears as tan, can see color to identify the level and quality of brown fused alumina.
Brown corundum sand with hydraulic careful screening, mechanical processing, screening and classifying the grinding materials, mainly used for grinding glass products, industrial cleaning and water cut, etc. On silicon chips, precision instrument, glass, ceramic, stone, leather, metal parts can improve smoothness and sandblasting cutting, is a manufacturer of grinding wheel, emery cloth, sand must be raw materials, can be used as building highway pavement, airport runway, wear-resisting rubber good wear resistant material. Brown fused alumina with high purity, good crystallization, strong liquidity, low linear expansion coefficient, enterprise production practice verification, the product in the process of application of blasting, powder, no crack characteristics, make it become the best in the brown just the quality of the jade of refractory aggregate and filling material

Brown fused alumina melt film precision casting sand is based on the production of the brown fused alumina and with special technology, it is produced by the careful organization of the researchers. The quality has reached the advanced level of similar foreign products through laboratory tests and production in practice of dozens of casting enterprises. And some performances of it can be adjusted or showcased according to the customers requirement. The precision casting sand with high refractoriness, low thermal expansion coefficient, good thermal stability, strong air permeability, high intensity, easy to shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratio is high as well. It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminum die casting industries, and can be processed in line with the demands of the clients.
Brown fused alumina is fused in the electric furnace with the high quality abrasive grade bauxite , coal and scrap iron as the raw material. Brown Fused Alumina for refractory is characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion ,good corrosion-resistance and so on. In particular, its performance-cost ratio is much higher than traditional Brown Fused Alumina, making Brown Fused Alumina become the best aggregate and padding of brown fused alumina refractory materials.
Brown fused alumina purposes Brown fused alumina called industrial teeth: mainly used in refractory materials, grinding wheel, sand blasting. 1. Sand corundum, sandblasting abrasive hardness is moderate, the bulk density is high, no free silica, than major, good toughness and okay brown fused alumina is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, washing jeans precision molds, and other fields; 2. The free abrasive, abrasive abrasive, applied to the tube, optical glass, monocrystalline silicon, lenses, clocks with glass, crystal glass, jade in areas such as free grinding, grinding is adopted widely in the domestic advanced materials; 3. The resin abrasive, abrasive has color appropriate, good hardness and toughness, suitable particle cross section type and keeping degree blade, used in resin abrasive, effect is ideal; 4) is coated with abrasive, abrasive abrasive paper, gauze and other manufacturers of production materials; 5. Brown fused alumina filler - is mainly used for automobile brake parts, special tires, special construction products such as led can be used as building highway pavement, airport runway, docks, car parks, industrial floor, wear-resisting material such as sports venues; 6. Filter medium, is a new kind of application field, abrasive using granular grinding for the bottom of the medium filter bed, purify drinking water or wastewater, is a new type of water filtration materials at home and abroad, especially suitable for non-ferrous metal processing, oil drilling mud weighting agent: 7. Hydraulic cutting - an abrasive abrasive cutting medium, rely on high pressure water jet cutting, basic application in the oil (gas) pipe, steel components, such as cutting, is a new type, environmental protection, safe way of cutting. Customer base: washed denim sandblasting room of shipyard shipyard steel structure factory powder factory our sandpaper, ShaBuChang crystal glass industry building floor steel hardware industry electronics qi car manufacturing coast terminals, hospital stadium parking lot.
