Since there are many types of silicon carbide, different materials and types of silicon carbide have different effects in the final use. Moreover, there is a big difference between the use of silicon carbide in foundries and steel mills. Generally, silicon carbide with a particle size of 0-10mm is a ferroalloy product used by manufacturers for smelting in small intermediate frequency furnaces and cupolas. In the process of steelmaking, the particle size is 0-10mm. The silicon carbide of silicon carbide acts as a deoxidizer and is often used by steel-making manufacturers to make ordinary steel, alloy steel and special steel.
The market price of 0-10mm silicon carbide ferroalloy is relatively expensive, so we must find a regular manufacturer, not only the price is low, but the quality is guaranteed. According to the different silicon content and carbon content of silicon carbide with a particle size of 0-10mm, the effect achieved during use is also different. Anyang Huatuo Metallurgical still recommends that you choose the secondary silicon carbide with a content of 88, because it contains Silicon and carbon content are high, so in the smelting process, the dissolution time is fast, the absorption rate is good, and it does not affect the steelmaking time. At the same time, it also reduces the production cost of metallurgical material manufacturers. 88 silicon carbide is also suitable for 80 tons and 100 tons. , 120 tons and other specifications of ladle.
Silicon carbide is a synthetic carbide with the SiC molecular formula. After being energized, it is usually formed by the high temperature of silicon dioxide and carbon of 2000°C or higher. The theoretical density of silicon carbide is 3.18g/cm3, its hardness is second only to diamond, between 9.2-9.8, and the microhardness is 3300kg/mm3, which is due to its high hardness, high wear resistance and high corrosion resistance . It is used in various mechanical parts with wear resistance, corrosion resistance and high temperature resistance. It is a new type of new engineering ceramic material.
Scope of application
There are four main application areas of silicon carbide: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. The raw material of silicon carbide can be supplied in large quantities and cannot be regarded as a high-tech product. The application of nano silicon carbide powder with extremely high technical content cannot form economies of scale in a short time.
(1) As an abrasive, it can be used as a grinding tool, such as grinding wheels, oilstones, grinding heads, sand tiles, etc.
(2) As a metallurgical deoxidizer and high temperature resistant material.
(3) High-purity single crystals that can be used to manufacture semiconductors and silicon carbide fibers.
Main application: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry. Snipe is used in semiconductors, lightning rods, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic membranes, cutting tools, Heating element, nuclear fuel, jewelry, steel, protective equipment, catalyst carrier and other fields.
