Best Selling OEM Sic Ceramic Stationary Ring Silicon Carbide Ceramic Sealing Ring

Product Description

 

Product Description

Product name:

Silicon Carbide Ring is made of silicon carbide as the main raw material, adding a variety of chemical wear-resistant raw materials and anti-oxidant, effectively improving the wear resistance of the product, using SiO2 micro powder as the high-temperature bonding phase, a high-performance silicon carbide products by high-temperature firing.

Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to corrosion from acids. Silicon carbide is an excellent ceramic material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles and cyclone components.

We produce sintered SiC tubes, reaction bonded SiC tubes and recrystallized SiC tubes. Our recrystallized SiC products have high purity, while our reaction bonded and sintered silicon carbide tubes have high mechanical strength. Our silicon carbide tubes possess good wearability, a low thermal expansion coefficient, extreme corrosion resistance, high hardness, and self-lubricating properties.

 

Advantage
1. Dimensional stability at high temperature, anti-deformation, high high temperature strength
2. Thermal shock resistance, wear resistance and corrosion resistance
3. Anti-oxidation and erosion resistance Can be widely used in: electric power, steel mill slag flushing groove, coal chemical industry, mining, transmission pipeline.

Application

 

Silicon carbide tubes are mainly used in medium frequency forging, various heat treatment electric furnaces, metallurgy, chemical industry, non-ferrous metal smelting and other industries. Widely used in metallurgical sintering furnace and intermediate frequency heating forging furnace. Length can be designed.
