Silicon Carbide Heating Element General Description

 

Silicon carbide heating element is a kind of non-metal high temperature electric heating element. It is made of selected high quality green silicon carbide as main material, which is made into blank, siliconization under high temperature and recrystallized. It is the most popular type of economical heating element capable of operating under hot and rigorous environments.

 

Silicon Carbide Heating Element Features

 

1. withstands as high as 1600°C

2. high strength and excellent shock resistance

3. heat source is free of noise and air pollution

4. anti-oxidization, anti- corrosion

5. easy to installation and maintenance

 

Applications of Silicon Carbide Heating Element

 

There are ED, U, W, H, Gun, Single Spiral, Double Spirals, Dumbbel, Door-like types and etc. which are widely used in various high temperature electric furnaces in air, vacuum and other protection gas environments and other electric heating devices, such as industries of magnet, ceramics, powder metallurgy, glass and machinery, etc.

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

Notice for using and installing:

1. Heater should be protected against damp during storing or installing to ensure the performance of the heater.

2. In order to be sure of well-distributed lod of each and groups, heater should be divided before assembling. The tolerance of the resistance of each one cannot exceed by 10% each other.

3. Heater is hard and brittle, please be careful when assembling and maintaining so as to avoid damage.

4. When operating the electric furnace at the beginning, the voltage should be increased slowly and cannot be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater.

5. When heater is damaged and need to be changed, the resistance of new one should follow the increasing resistance. If many are damaged or resistance increased too much, heater should be changed.
