High Temp ISO9001 Silicon Carbide Heating Rod
The descrioition of Silicon Carbide Heating Rod
1. The silicon carbide (SIC) heating element is a kind of non-metal high temperature electric heating element. It is made of selected super quality green silicon carbide as main material, which is made into blank, solid under high temperature and re-crystallized.
2. Compared with metal electric heating element, this element is characterized by high-applied temperature, anti-oxidization, anti-corrosion, long service life, little deformation, easy installation and maintenance.
3. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramic, powder metallurgy, glass, metallurgy and machinery etc.
Advantages of silicon carbide electric heating element:
1. High temperature resistance
2. Oxidation resistance
3. Corrosion resistance
4. Fast temperature rise
5. Long service life
6. Small deformation at high temperature
7. Easy installation and maintenance
8. Good chemical stability
9. Fast heating speed
10. Environmental protection
11. Energy saving
Electric property of Silicon Carbide Heating Rod
SiC heating elementshas rather large specific resistance. when the surface temperature of the hot zone reaches to 1050 heating in air, its resistance rate is 600~1400Ωmm2/m.Its resistance changes with the temperature rise.From room temperature to 800 is negative value,over 800 is positive characteristic curve:
