Good Abrasion Resistance Refractory Silicon Carbide
Description
Technical Parameters
Introduce
Silicon carbide products are refractory materials produced using silicon carbide sand as the main raw material and different adhesives. Its thermal conductivity is high, about 10-14 times that of clay products; Low coefficient of expansion, good thermal stability, high temperature and pressure resistance, high flexural strength, stable chemical properties, and continuous improvement of adhesives in recent years have overcome the weaknesses of easy oxidation and alkali corrosion. Therefore, silicon carbide products are not only essential refractory materials for vertical zinc smelting, but also widely used in industrial furnaces such as steel metallurgy, chemical industry, ceramics, as well as anti-corrosion and wear-resistant pumps and pipeline linings. It can maintain high mechanical strength at temperatures up to 1650 ° C. It has higher chemical corrosion resistance than other ceramics. At the same time, it has been applied in the refractory lining and heating elements of industrial furnaces, worn parts of pumps and rocket engines, and semiconductor substrates for light-emitting diodes.
Innovaccer offers a full range of full density silicon carbide ceramic materials.
Features:
Silicon carbide refractory material is a hard material with excellent mechanical properties, high hardness, strong wear resistance, and high compressive strength. This allows it to withstand various mechanical pressures and impacts in high-temperature environments, making it less prone to rupture or fracture.
It also has excellent corrosion resistance. It can resist the erosion of chemical substances such as acid and alkali, so it can be used for a long time in corrosive media without damage. This makes silicon carbide refractory materials have many applications in the chemical industry.
It not only has good fire resistance, but also has good thermal conductivity and conductivity. Its thermal conductivity and thermal shock stability (up to 1200-1600 degrees Celsius) are very good, several times that of traditional ceramic materials, which can effectively conduct heat, avoid local overheating and thermal diffusion. This enables the widespread application of silicon carbide refractory materials in equipment such as furnaces and melting furnaces.
In addition, silicon carbide refractory materials also have good thermal insulation performance. Its low thermal conductivity can effectively prevent heat conduction and maintain the stability of other materials in high-temperature environments. This makes silicon carbide refractory materials have important applications in high-temperature insulation and thermal insulation fields.
In summary, silicon carbide refractory material is an excellent high-temperature material. It has the characteristics of high temperature resistance, wear resistance, corrosion resistance, excellent thermal conductivity, thermal insulation performance, and long service life, so it has a wide range of application prospects in multiple fields.
