SiC Heater Element

Product Introduction：
SIC Refractory Products is made by technical and management of science process,with selected material as raw material and useful for under high temperature environment and meet  energy-saving.
SIC radiation pipe is high temperature tolerance,high thermal conductivity,low coefficient of thermal expansion,oxidation resistance,thermal shock resistance,long application life.They are the best materials in steel metallurgy industry.
 
Product Highlights:
1. Excellent in dimensional stability as well as high loading ability at high  temperature
2. High thermal conductivity at room temperature
3. Low room temperature strength and wear resistance
4. Excellent antioxidant properties
 
Application:
Slicon carbide heat exchanger is the best substitute for stainless steel and graphite heat exchanger because of its comprehensive corrosion resistance,good heat transfer effect and long service life.High efficiency, energy saving, clean, stable quality and small space occupancy are of great significance to the continuous normal operation of industrial production.Its excellent performance of high temperature resistance and thermal shock resistance, which can be air-cooled from 1200 ° C to room temperature without cracking, has high corrosion resistance and heat transfer efficiency, and is widely used in various industrial kiln exhaust gas recycling and reuse.
