High temperature high performance sic heating rods

Sic heating rod

Sic heating rod is a kind of non-mental high temperature electric heating element. It is made of selected high-purity green silicone carbide as raw material which is made into blank and silicone crystal under high temperature of 2400^.C. It can usually make use for furnance which temperature from 600^.C-1600^.C. It can widely used in various electric heating element of glass,chemical, electronic material and so on.

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 assem bling 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 ne should follow the increasing resistance. If many are damaged or resistance increased too much, heater should be changed.
