Silicon carbide (SIC) heating elements are manufactured from recrystallized high purity alpha silicon carbide rod or tubular form. Optimized structure of SiC particles make it have special characteristics as applied in industry and lab, which have the best service life particularly in oxidation and/or corrosive atmospheres. Another feature is that elements can be replaced when the furnace is in continuous operation, thus avoiding a shutdown. Its high loading capacity is suitable for low- volume and high power conditions. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices.

Application

high purity 1625C Double Spiral Silicon Carbide Sic Old Furnace Parts dental factory Sic Heating Element high temperature furnace silicon carbide rod china

Silicon carbide (SiC)  heating element can be used in the furnace temperature 600C-1400C, directly in the air use as well, and it need not any protective atmosphere. Because of SiC heating elements well performance, they are widely used in high temperature furnace, ceramics, glass, analysis and test, semiconductor, science research.. etc

Installation Instructions:

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.
