What are the advantages of silicon carbide for the foundry industry?
The history of the development of silicon carbide is quite old, the development of silicon carbide in the foundry industry is also gradually active.
Silicon carbide in the casting industry will have more room for development.
1. Silicon carbide In the casting industry can add silicon by carbon, because silicon carbide is a composite element, it is more convenient to use. When the carbon content of silicon carbide is higher than 23%, the casting can be carbonated.
2. Silicon carbide in the casting industry can also play a role in deoxidation.
3. Silicon carbide in the casting can also play a role in breeding, the application of silicon carbide particles in the market are generally low-grade silicon carbide, the content of 50-60%, with a piece of ferrosilicon or alone. Remember not to join too much.
4. The use of silicon carbide casting performance can be stable, the use of management are more convenient.
Thus, the application of silicon carbide in the foundry industry has made great progress.
Silicon carbide materials applications
1, building materials ceramic wheel industry: the use of silicon carbide thermal conductivity, high heat strength of the characteristics of manufacturing thin-walled kiln furniture, not only can reduce the kiln furniture capacity, but also increased the kiln capacity and product quality, shorten the production cycle, It is the ideal indirect material for ceramic glaze baking. At the same time, silicon carbide ceramic made by adding silicon carbide is also a good heat-resistant ceramic product.
2, non-ferrous metal smelting areas: the use of silicon carbide with high temperature, high strength, good thermal conductivity, impact resistance, high temperature indirect heating materials, such as strong tank distillation furnace, distillation tray, aluminum electrolytic cell, copper melting furnace Lining, Zinc Furnace arc plate, thermocouple protection tube.
3, the steel industry: the use of silicon carbide corrosion resistance, thermal shock resistance to wear, good thermal conductivity for large blast furnace lining to improve the service life.
4, metallurgical beneficiation industry: silicon carbide hardness second only to diamond, with strong wear resistance, wear-resistant pipe, impeller, pump room, cyclone, mine liner ideal material, the wear resistance of cast iron Rubber life 5-20 times.
5, energy-saving materials: the use of good thermal and thermal stability, silicon carbide used as heat exchanger manufacturing, can reduce fuel consumption by 20%, saving 35% of fuel. Silicon carbide new material is also widely used in aerospace. China's first rover or aluminum-based silicon carbide and other materials will be manufactured.
6. Semiconductor Photovoltaic Industry: Due to the unique and excellent physical and electronic properties of silicon carbide with wide energy level, high breakdown electric field, high thermal conductivity and high saturated electron transport speed, it has become the best material in the field of semiconductors. Such as: blue light-emitting diodes, UV detectors, high-pressure diode, high-power microwave, and a variety of high-temperature devices such as high temperature.
