synthetic corundum
The difference between silicon carbide abrasive and brown corundum smelting: white corundum is produced by dumping method, and the lining construction material is usually white corundum sand or aluminum oxide powder. Usually, graphite or white corundum refractory products are used as lining. For the production of white fused alumina by frit method, the lining needs good heat insulation and air permeability. The furnace body is divided into lining type and unlined type. The receiving bag includes an unlined receiving bag and a lined receiving bag. Unlined seam bags shall be forced water cooled. For consolidated pink aluminum oxide abrasive grinding, brown corundum abrasive is consolidated by binder to make abrasive tools. When the tool is placed on the abrasive tool, due to the role of binder, not only the large-size. The general particle size is from F4 to F320, and its chemical composition depends on the particle size. Brown alumina abrasive can contact with the surface of the workpiece, but also many small-size Brown alumina abrasive can contact with the surface of the workpiece, so that the number of green carborundum abrasive in contact with the surface of the workpiece is large, and the number of brown alumina abrasive involved in the grinding process is large, and the pressure of each white aluminum oxide abrasive is small It has the advantages of small strength, shallow grinding depth, small distance between brown corundum abrasives, small machined surface roughness value and high machined surface quality. brown aluminium oxide has the characteristics of large volume density, low porosity, good volume stability and thermal shock resistance. It is a high-grade refractory raw material with good effect. With the improvement of product quality, the application scope is still expanding. Characteristics of brown fused alumina manufacturer: the product granularity is produced according to international standards and national standards, and can be processed according to the granularity required by users. Brown corundum, also known as black silicon carbide, is a brown artificial corundum made of bauxite, carbon materials and iron scraps by melting and reducing in an electric arc furnace, so it is named for this. The main chemical composition of brown corundum is Al2O3, with the content of 95.00% - 97.00%. In addition, it contains a small amount of Fe, Si, Ti, etc. Brown corundum is the most basic abrasive, because of its good grinding performance, wide range of application, low price, is widely used. The technological process of white fused alumina manufacturer is as follows: corundum block - coarse crushing - medium crushing - crushing - segmented screening - magnetic separation - fine screening - Inspection - packaging Black corundum is mainly used for free grinding, such as bottom polishing before electroplating of metal parts, aluminum products, polishing of bicycles, motorcycles, sewing machines, clock parts, lighting, plastics and hardware tools, sandblasting (rust removal, glass spray), processing materials, manufacturing resin cutting pieces, angle grinding pieces and coated abrasives.

Brown fused alumina abrasives must be stored in the open air during the summer. They should not be stored in the open air. They should not be covered for a long time. Keep them dry and dry to prevent the brown fused alumina abrasive from getting wet. Ensure that the brown fused alumina abrasive does not come into contact with the sundries, in order to ensure the smooth breathing of the brown fused alumina abrasive and prevent the impurities from blocking the capillary void of the brown fused alumina abrasive. Brown fused alumina abrasives need regular cleaning, waxing, regular dust removal, and water maintenance.
The development and application of brown corundum dust powder coating has developed several brown corundum dust powder coatings. The brown corundum sandblasting is made by fused high quality bauxite ore. The brown corundum blasting is made of cooked bauxite and iron. The shavings and coke are matched according to a certain ratio. The characteristics of the brown fused alumina sandblasting include the content level. The brown aluminum oxide is in the pretreatment method of various types of table. The effect of brown corundum blasting is the most complete and the most adaptable. The most limited. Several advantages of white corundum fine powder abrasive: it does not affect the color of the processed parts. It can be used for sandblasting in the process of prohibiting the residual iron powder. The amount of iron oxide contained is extremely low. It is suitable for sandblasting operations where iron residue is strictly prohibited. Wash the steps to remove impurities. white corundum fine powder is not only a high-grade abrasive material, but also an advanced grinding and polishing material. It is made of abrasive tools for grinding high carbon steel, high speed steel and various stainless steels. brown fused aluminum oxide is a polishing medium in which the acceleration and velocity of particles in a gas stream are the effect of white corundum inertia and particle size. Mentioning "black corundum" may not be known to many people. It is true that this new type of wear-resistant material is not something that ordinary people can use in life, so ordinary people do not understand this material, but its The range of use is generally very extensive in industrial manufacturing applications. The stainless steel is polished with brown fused alumina, white corundum and other abrasives. After polishing, the surface color of the stainless steel is inconsistent. In some places, the darkness and discoloration of the black hair will appear. After the white aluminium oxide is thrown, the surface will be uniform in color and reveal the uniformity of the stainless steel. In the late 1970s, domestic production began. Stainless steel is widely used because of its high wear resistance, unique strength, superior corrosion resistance and rust resistance. Among the 10 product companies surveyed, none of the 9 product companies considered chrome corundum instead of brown corundum. Only one company considered substitution, but after the test, the product company finally chose brown fused alumina. Due to cost considerations, chrome corundum has no price advantage. In the overall background of the refractory market, the priority of product companies is to save production costs. Second, in terms of effects, after testing, the company believes that chrome corundum is used instead. Brown fused alumina has not achieved the expected results. If the use of black corundum is still required, a lot of tests and process improvements are needed. The test cost is too high and the energy is too much. |
