1400 degree High purity long using life DB type sic heating element for metallurgy industry

The SiC electrothermal element is a rod-shaped non-metallic thermoelectric element which is made of high quality green SiC as the main raw material through processing, high temperature silicification and recrystallization. 

It can be widely used in such applications as sintering and heating elements of ceramics, magnet, glass, metallurgy, refractory, etc.

1.) ED(rod)type elements

2.) DB(dumbbell)type elements

3) U type elements

4) W(three phase)type elements

5) SC(single spiral)type element

6) SC(double spiral)type elements

7) UX(slot)type elements

1) Physical properties

2) Chemical Properties

1. Antioxidant property of elements

2. Alkali&alkaline metal oxide will come out alkali-chemical corrosion

3.Melting metal can corrade the element and affect the life.

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.
