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.
