Corundum grinding wheel

Corundum bauxite, coke (anthracite) as the main raw material in electric arc furnace at high temperature smelting, corundum main chemical components of AL2O3, its content is 94.5% -97%, and the other containing a small amount of TiO2, SiO2 and Fe2O3 and so on, like SiC high toughness, hardness of 1800-2200kg / mm2, bulk density ≥3.85g / cm3, temperature, refractoriness up to 1850 ℃. above 2200 ℃ high temperature furnace purification, cleaning, crystallization, sorting, crushing , magnetic separation, screening and other processing methods into a variety of particle size of the product. Its dense texture, high hardness, formation of spherical particles, for the manufacture of ceramics, resins and high abrasive grinding, polishing, sand blasting, precision casting, etc., can also be used to manufacture advanced refractories. Corundum P gravel in corundum F on the basis of standard sand by sieving and washing after further treatment process from processing. This corundum P sand without calcination, the shape is tapered, high grinding force, good self-sharpening, for doing all kinds of coated abrasives products, such as sandpaper, Shabu, belt and so on. Corundum wheel classification: by the abrasive can be divided into ordinary abrasive (corundum and silicon carbide) wheel. According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, cup wheel, disc wheel and so on; by binding agent can be divided into pottery wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters of the grinding wheel abrasive, grain size, hardness, binders, organization number, shape, size, line speed. Since the wheel typically operate at high speed, before turning test should be carried out so that the use of (guaranteed at the maximum operating speed of the wheel, do not break) and static balance test (when working to prevent vibrations caused by the machine). Grindstone at work for some time, it should be trimmed in order to restore the grinding performance and correct geometry. From the shape into flat wheels, double-sided concave grinding wheel, double bevel wheel, cylindrical grinding wheel, disc wheel, bowl grinding wheel, according to the needs of the machine structure and the grinding wheel into various shapes and sizes. Corundum grinding wheel outer diameter should be as the election was bigger, in order to increase the speed of the wheel circumference, so to improve the productivity of grinding and surface roughness favorable. In addition, under the conditions of the machine rigidity and power permit, such as the choice of the width of the larger wheel, also can receive to improve productivity and reduce the effect of roughness, but high grinding heat-sensitive materials in order to avoid burns and workpiece surface cracks, wheel width should be appropriately reduced. Dioxide for each color after calcination corundum toughness plays a major factor, when the corundum particles are fired in an oxidizing atmosphere. Because, solid solution, has led to the original brown blue. Is titanium, titanium can be dissolved in the alumina crystals in the three-oxo titanium oxide into a more stable, then wrapped in aluminum die-oxo-in, and for the relevant speed growth, strength and toughness largest squint occurs before corundum blue, light blue over 1300 degrees, 1400 degrees deep blue. corundum flat-shaped grinding wheel, corundum grinding wheel sheet (resin sheet, rubber sheet), corundum cymbals wheels are large wide range of products, but also the main varieties of quality checks. Spot checks found that quality problems are more concentrated in the rotation strength, diameter, hardness, static balance, the quality characteristics of form and position tolerances, product signs.
