Sic Silicon Carbide Particle Size Sand Black Carborundum Green Silicon Carbide for Abrasive Materials and Metal Smelting
Silicon carbide for abrasive is prepared by mixing high-quality quartz sand and petroleum coke through high-temperature roasting, crystal generation process supplemented by crushing and pickling process. It has high hardness and wear resistance. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum.
The price of our asphalt coke, cheap graphite crucible, plumbago graphite is determined according to the price of the international market, fully taking into account the interests of both our company and our customers. Each after-sales service personnel have many years of experience to ensure that they can solve problems quickly and accurately for customers. We have accumulated a wealth of experience through years of research and industry practice. We carry out strict quality process control and continuously improve the quality assurance system.
Silicon Carbide for Abrasive (SiC) is made of quartz sand, petroleum coke (or coal coke) and other raw materials through high temperature smelting in a resistance furnace. They are all hexagonal crystals, with a specific gravity of 3.20~3.25, and a microhardness of 2840~3320kg/mm², all of which belong to a-SiC. Silicon carbide is suitable for abrasives due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance.
The thermal equipment for preparing SiC smelting block at high temperature is a special silicon carbide electric furnace. Its structure consists of a furnace bottom, an end wall with electrodes on the inner surface, a detachable side wall, and a furnace core body (full name: energized heating element in the center of the electric furnace. Graphite powder or petroleum coke is installed in the center of the charge according to a certain shape and size, generally round or rectangular. Its two ends are connected with electrodes). The high-power electric furnace needs to be heated for about 24 hours. After the power failure, the reaction to generate SiC is basically over. After SiC>96% bulk materials are classified, coarsely crushed, finely crushed, chemically treated, dried and sieved, and magnetically separated, they become black SiC particles of various sizes.It can be used to manufacture grinding wheels, oilstones, coated abrasives or free grinding.
Silicon carbide sandblasting and rust removal: This product is made of fine powder after high-strength pressure extrusion and high-temperature sintering, it will get the features of moderate hardness, tidy and clean, not easy to break, repeated use, and good sandblasting effect.
