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.

Notice for using and installing SIC heater
1. Be protected against damp during storing or installing to ensure the performance ;
2. Divided before assembling. The tolerance of the resistance of each one cannot exceed by 10% each other;
3. Be careful when using and maintaining;
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 ne should follow the increasing resistance. If many are damaged or resistance increased too much, heater should be changed.
