silicon carbide products application
Silicon carbide products are ubiquitous in today's world, not only because of its wide variety, but also because of its excellent performance, which can be applied to various fields. There is no unified definition of silicon carbide products. But first of all, we affirm that it is made of silicon carbide according to various processes. Silicon carbide products can be divided into many categories, according to different use environment, into different categories.
Generally used to mechanical more. For example, when applied to mechanical seal, it can be called silicon carbide seal ring, which can be divided into static ring, dynamic ring, flat ring, etc. According to the special requirements of customers, we can also produce various shapes of silicon carbide products, such as silicon carbide special-shaped parts, silicon carbide plate, silicon carbide ring, etc. Therefore, the definition of silicon carbide products is roughly based on the definition of materials and specifications, using silicon carbide materials to make various shapes and specifications of silicon carbide products.
Silicon carbide is mainly used in four fields: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. The raw material of silicon carbide can be supplied in large quantities, which can not be regarded as high-tech products. However, the application of nanometer silicon carbide powder with high technology content in a short time can not form scale economy.
1. Application of nonferrous metal smelting and manufacturing industry
The use of silicon carbide has heat resistance, high hardness, excellent heat transfer performance, impact resistance, as a high temperature indirect heating material, such as hard filling distillation furnace. Rectifying furnace tray, aluminum electrolytic cell, copper melting furnace lining, arc plate for zinc powder furnace, thermocouple protection tube, etc.
2. Application of iron and steel enterprises
Use silicon carbide for corrosion resistance, heat resistance, impact resistance and wear resistance. With the good heat transfer characteristics, the lining of large and medium blast furnaces can be used to improve the service life.
3. Application of processing industry in metallurgical smelter
Silicon carbide is the best material for wear-resistant pipes, impellers, pump rooms, hydrocyclones and ore hopper linings. It has a corrosion resistance of 5-20 times that of cast iron and plastic. It is one of the ideal materials for aviation runway.
4. Application of industrial ceramics and grinding wheel manufacturing industry
With the help of its heat transfer coefficient. With the characteristics of heat transfer and high firing rigidity, the production of plate kiln furniture can not only reduce the storage capacity of kiln furniture, but also improve the loading capacity and product quality of kiln and reduce the manufacturing period. It is an ideal indirect material for baking and calcining the glaze layer of porcelain.
5. Application of energy conservation
Using excellent heat transfer and thermal stability as heat exchanger, fuel consumption is reduced by 20%, combustion supporting agent is saved by 35%, and output rate is increased by 20-30%. In particular, the anti-wear level of the discharge and transportation pipeline used in the mine concentrator is 6-7 times that of the general wear-resistant material.
