Product Description

1200 ℃ SiC Heater Electric Furnace Heating Element

 

Electrical properties of SiC Heater

Silicon carbide has a large specific resistance, ohmic heating in the air, the surface temperature of the heating unit 1050 ± 50 ℃, the resistance was 600-1400Ω-mm2 / M. As silicon carbide resistance with increasing temperature change, from room temperature to 800 ℃. Resistance - temperature characteristic curve is negative, positive temperature higher than 800 ℃.

 

SiC Heater Advantages

 

•  High purity raw materials;

•  Maximum temperature being up to 1500℃ (2732°F);

•  Easy to be installed and replaced.

W type SiC heaters can be installed and replaced while the tin bath is operation. The heaters can be installed through the side-seal, or through the side of the bath roof, and are commonly used to extend campaign lives, where conventional elements in the side zones have been broken, and insufficient power is available.
