Product Description

Silicon Carbide Heating ElementDescription

 

Silicon Carbide Heating Element 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.

 

Silicon Carbide Heating Element Advantages

 

High purity raw materials;

High structural density;

Slow aging;

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

Easy to be installed and replaced.

Recommended surface load and Influences to Surfaces of the Elements in Different Operating TemperatureS

atmosphere Furnace Temperature(°C) Surface Load(W/cm2) The influence on the Rod
Ammonia 1290 3.8 The action on SiC produces methane and destroys the protection film of SiO2
Carbon dioxide 1450 3.1 Corrode SiC
Carbon monoxide 1370 3.8 Absorb carbon powder and influence the protection film of SiO2
Halogen 704 3.8 Corrode SiC and destroy the protection film of SiO2
Hydrogen 1290 3.1 The action on SiC produces methane and destroys the protection film of SiO2
Nitrogen 1370 3.1 The action on SiC produces insulating layer of silicon nitride
Sodium 1310 3.8 Corrode SiC
silicon dioxide 1310 3.8 Corrode SiC
Oxygen 1310 3.8 SiC oxidized
Water-vapor 1090-1370 3.1-3.6 The action on SiC produces hydrate of silicon
Hydrocarbon 1370 3.1 Absorb carbon powder resulted in Hot pollution
