Features of silicon carbide products

Silicon carbide crucible products are at room temperature, high temperature and high strength. High thermal conductivity. The coefficient of linear expansion is small. Good thermal shock resistance. Good abrasion resistance at high temperature. A range of excellent properties, such as strong resistance to chemical attack.

It has been widely used in steel. Nonferrous metallurgy. Chemistry. Electricity. Ceramics, aerospace and other industrial fields. With the deepening of the application research of silicon carbide refractories and the improvement of production level, the demand is increasing year by year, and the application field is expanding

use

1. Silicon carbide is used in the non-ferrous metal smelting industry, which has the advantages of high temperature resistance, high strength, good thermal conductivity, and impact resistance. As a high-temperature indirect heating material, such as a hard pot distillation furnace. Distillation furnace tray, aluminum electrolytic cell, copper melting furnace lining, zinc powder furnace arc plate, thermocouple protection tube, etc.

2. Applications in the steel industry take advantage of the corrosion resistance, thermal shock resistance and wear resistance of silicon carbide. Good thermal conductivity increases the service life of large blast furnace linings.

3. The hardness of silicon carbide in the metallurgical beneficiation industry is second only to diamond, and the wear resistance is strong, and it is a wear-resistant pipeline. Impeller. Pump chamber. Cyclone. The ideal material for the inner lining of the mine bucket is 5-20 times longer than the service life of cast iron and rubber, and it is also one of the ideal materials for the aviation runway.

4. The application of architectural ceramics and grinding wheel industry makes use of its thermal conductivity. The thermal radiation, high thermal strength and manufacturing of thin plate kiln furniture can not only reduce the kiln capacity, but also improve the kiln capacity and product quality, and shorten the production cycle. It is an ideal indirect material for ceramic glaze baking and sintering.

5. Energy-saving applications use good thermal conductivity and thermal stability as a heat exchanger, reducing fuel consumption by 20%, saving fuel by 35%, and increasing productivity by 20-30%. In particular, the wear resistance of the discharge and transmission pipeline of the mine concentrator plant is 6-7 times that of ordinary wear-resistant materials.
