Product Details
Single Spiral Sic Heating Element Heater
Single Spiral Sic Heating Element Heater with a spiral-grooved heating section, are more resistant to heat and corrosion than conventional products and are able to withstand operation in rigorous conditions.
Single Spiral Sic Heating Element Heaters are made of selected super quality green silicon carbide as main material, which is made into blank, silicide under high temperature and re-crystallized. Max temperature 1600 deg C. Single Spiral SiC Heating elements are provided with energy-saving, low-resistance, cold-end terminals.
Characters of Single Spiral Sic Heating Element Heater
1.) Low expansion coefficient
2.) Little deformation
3.) Stable chemical property
4.) Long service life
5.) Easy installationand maintenance

Application of Single Spiral Sic Heating Element Heater
It can usually make use for furnace which temperature from 600-1600. It can be directly used in an air atmosphere, without any protection atmosphere.
It is extensively used in the fields of metallurgy, ceramics, glass, machinery, analysis test, semiconductor, science & research and so on.
Notes 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.
