Silicon Carbide Sic Heating Element
Spiral shaped sic heaters
Working temperaure:900-1400℃
OD: 16mm-54mm Overall Length: 300mm-4300mm
Products Description
Spiral shaped sic heaters are thin in the middle and with sprial lines on the surface. The heater’s normal use temperature can reach 1450℃ in oxidizing atmosphere and it even can be used more than 2000 hours. While matching with the automatic electric control system, it can get accurate constant temperature and adjust the temperature automatically depending on the curve according to the needs of the production process. Silicon Carbide Sic Heating Element is convenient, safe and reliable.
Properties
* High cold and heat-resistance. * Long service time * Coefficient of linear expansion: 5×10-6 (1/℃) [2]. * Thermal conductivity: 20 kcal/m·hour·degree. * Component texture: hard and brittle, resistant to rapid cold and heat, not easy to deform under high temperature. |  |
