Green Wheel

Green silicon carbide grinding wheel grinding wheel generally refers to the use of green silicon carbide production, color is green. Because of the characteristics of the material itself, the workpiece can be widely used in hard and brittle materials, but generally not suitable for processing large material toughness. 1. abrasive sharp, high hardness, can grinding carbide, optical glass, ceramics, alloys and other hard and brittle materials. 2. brittle, so keep corners poor, not suitable for processing large workpieces toughness. 3. good thermal conductivity, thermal deformation of the workpiece grinding fit. Monocrystalline corundum grinding wheel is somewhat similar, but the performance is not the same. 4. Since the material itself is relatively sharp, green silicon carbide grinding wheel can also be used in the processing of precious stones and other products. Silicon carbide (SiC) is used, petroleum coke (or coal), wood as a raw material by high temperature smelting. Silicon carbide also exists in nature, rare. Also known as silicon carbide. In contemporary C, N, B and other non-oxide high-tech, the silicon carbide is most widely used and most economical. It can be called or refractory sand. Silicon carbide is made of quartz sand, petroleum coke (or coal), wood (need to increase the production of green silicon carbide salt) and other raw materials in high temperature resistance furnace smelting. China's industrial production is currently divided into black silicon carbide, silicon carbide and green silicon carbide are two, are hexagonal, a specific gravity of 3.20 - 3.25, the hardness of 2840 ~ 3320kg / mm2. Including black and green silicon carbide, wherein: black silicon carbide is quartz sand, petroleum coke and high silica as the main raw material, through high temperature resistance furnace smelting. Its hardness between corundum and diamond, the mechanical strength than corundum, brittle and sharp. Green silicon carbide are petroleum coke and high silica as the main raw material, add salt as an additive, smelting furnace by high temperature resistance. Its hardness between corundum and diamond, the mechanical strength than corundum. Commonly used silicon carbide abrasive two different crystals, a green silicon carbide, containing more than SiC 97%, gold is mainly used for grinding hard tool. Another black silicon carbide, a metallic luster, containing more than SiC 95%, stronger than green silicon carbide large, but low hardness, mainly cast iron and non-metallic materials for the mill. Green silicon carbide (GC) wheel, green silicon carbide materials, especially for high grinding hardness and brittle materials, such as optical glass and carbide. For the convenience of customers, in order I produced a variety of abrasive grinding wheels, please indicate the workpiece material, hardness, wear the number, in order to better provide you with high quality products and services ordered.
