Belongs to the smelting industry;

Application scope

Silicon carbide has four main application areas, namely: functional ceramics, high-end refractory materials, abrasives and metallurgical raw materials . Silicon carbide coarse material has been supplied in large quantities and cannot be considered a high-tech product. However, the application of nano-scale silicon carbide powder with extremely high technical content is unlikely to achieve economies of scale in a short time.

Abrasives

Mainly used in the production of grinding wheels, sandpaper, abrasive belts, whetstones, grinding blocks, grinding heads, abrasive pastes and monocrystalline silicon, polycrystalline silicon in photovoltaic products and the electronics industry Grinding and polishing of piezoelectric crystals, etc.

Chemical industry

It can be used as a deoxidizer for steelmaking and a modifier for the structure of cast iron. It can be used as a raw material for manufacturing silicon tetrachloride and is the main raw material for the silicone resin industry. Silicon carbide deoxidizer is a new type of strong composite deoxidizer, which replaces the traditional silicon powder and carbon powder for deoxidation. Compared with the original process, the physical and chemical performance is more stable, the deoxidation effect is good, the deoxidation time is shortened, energy is saved, and the deoxidation rate is improved. It is of great value to improve steelmaking efficiency, improve steel quality, reduce raw and auxiliary material consumption, reduce environmental pollution, improve working conditions, and improve the comprehensive economic benefits of electric furnaces.

"Three-resistant" materials

Silicon carbide is used for corrosion resistance, high temperature resistance, high strength, good thermal conductivity, impact resistance and other properties. On the one hand, silicon carbide can be used in various smelting Furnace linings, high-temperature furnace components, silicon carbide plates, lining plates, supports, saggers, silicon carbide crucibles, etc.

On the other hand, it can be used as high-temperature indirect heating materials in the non-ferrous metal smelting industry, such as vertical tank distillation furnaces, distillation furnace trays, aluminum electrolytic cells, copper melting furnace linings, and arc-shaped zinc powder furnaces. plates, thermocouple protection tubes, etc.; used to make high-order silicon carbide ceramic materials that are wear-resistant, corrosion-resistant, and high-temperature resistant; and can also be used to make rocket nozzles, gas turbine blades, etc. In addition, silicon carbide is also one of the ideal materials for solar water heaters on highways, aviation runways, etc.

Non-ferrous metals

Silicon carbide is used as a high-temperature indirect heating material with high temperature resistance, high strength, good thermal conductivity, and impact resistance, such as pot distillation furnaces and distillation furnace trays. , aluminum electrolytic cells, copper melting furnace linings, arc plates for zinc powder furnaces, thermocouple protection tubes, etc.

Steel

Taking advantage of silicon carbide's corrosion resistance, thermal shock resistance, wear resistance, and good thermal conductivity, it is used in the lining of large blast furnaces to increase its service life.

Metallurgical beneficiation

The hardness of silicon carbide is second only to diamond and has strong wear resistance. It is the ideal lining for wear-resistant pipes, impellers, pump chambers, cyclones, and ore hoppers. It is an ideal material and its wear resistance is 5-20 times that of cast iron and rubber. It is also one of the ideal materials for aviation runways.

Building Materials Ceramic Grinding Wheel Industry

Making use of its thermal conductivity, thermal radiation, and high thermal intensity characteristics to manufacture thin plate kiln furniture can not only reduce the capacity of the kiln furniture, but also improve the efficiency of the kiln. The filling capacity and product quality shorten the production cycle, and it is an ideal indirect material for baking and sintering of ceramic glazes.

Energy Saving

Utilizing good thermal conductivity and thermal stability as a heat exchanger can reduce fuel consumption by 20%, save fuel by 35%, and increase productivity by 20-30%, especially The wear resistance of the discharge pipeline used in mine dressing plants is 6-7 times that of ordinary wear-resistant materials.

The abrasive particle size and composition are in accordance with GB/T2477--83. The determination method of abrasive particle size composition is in accordance with GB/T2481--83.

Jewelry

Synthetic Moissanite, also known as synthetic moissanite and synthetic silica carbide (chemical composition SiC), has a dispersion of 0.104 larger than diamond (0.044) and a refractive index 2.65-2.69 (diamond 2.42), with the same diamond luster as diamonds, with stronger "fire" and closer to diamonds than any previous imitations. This is manufactured by C3 Company in North Carolina, USA. It has patents for the production of synthetic silicon carbide in various countries around the world and is being promoted and applied around the world. What is the industry category of Shanghai Space Administration?

The company’s industry category: Aerospace.

Just look at the business license and you will know. What is the industry category of catering?

What is the industry category of underground parking lots in the service industry?

The industry category of underground parking lots mainly depends on the type of campsite in the corporate living area. Does it belong to the supporting facilities of the industrial zone? The supporting facilities of the industrial zone refer to the necessary production auxiliary facilities and living auxiliary facilities set up within the industrial zone, including single dormitories, staff canteens, industrial office buildings and warehouses, etc. For industrial areas, the most important supporting facilities are single dormitories. There are two types of single dormitories in terms of land use. The first type is a single dormitory area that is built in large areas outside of industrial land, has certain living supporting facilities, and has relatively independent living and living functions. When conducting land use statistics, It shall not be included in industrial land (M), but shall be included in the third category of residential land (R3) for statistics, and planning and construction shall be carried out in accordance with the relevant standards for residential land. The second type is single dormitories built in first- and second-class industrial zones in order to facilitate employees' commuting. However, they also need to occupy separate land for construction and are not allowed to be mixed with industrial plants.

They should also be Necessary hygiene and environmental protection measures must be taken to meet the spacing requirements for residential buildings; such single dormitories should be included in industrial land (M) when conducting land use statistics. To put it simply, if it belongs to a family area, it generally belongs to the second category of residential land. The underground garage belongs to the second category of residential land and does not belong to the road land.
