Product Description

ED Type SiC Heater Silicon Carbide Heating Element, a experience of more than 3 decade in manufacturing of SiC Heaters Silicon Carbide Heating Element, STA occupies a majority share in this range.

SiC Heaters Silicon Carbide Heating Element  is a kind of non-metal high temperature electric heating element.It is 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.

 

Production process: made into blank, silicided under high temperature and re-crystallized.

Character: high-applied temperature anti-oxidization ,anti-corrosion ,long service life ,little deformation, easy installation and maintenance.

Usage: heaters silicon carbide sic heating element used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramics, metallurgy ,glass, and machinery.

Type: we have rod ,u, w, h, gun, single spiral, double spiral, dumbbell, door like type SiC Heaters Silicon Carbide Heating Element. 

SiC Heaters Silicon Carbide Heating Element have rather large specific resistance. When it is heated in air and the surface temperature of the hot zone reaches 1050°C,it's resistance rate is 600-1400mm2/mm and its resistance value changes as the temperature rises which is negative value from room-temperature to 800 °C  and is postive value nature over 800 °C .

The key factor to the optimum service life of the element is to select the surface load of the element correctly according to the furnace construction, atmosphere and temperature. The figure shows the relation between furnace temperatures, element temperature and element surface load under the condition that the element radiation is not obstructed.

 

We are the leading manufacturer of SiC products in China since 1971, Especilly in SiC Heaters Silicon Carbide Heating Element.

4. Advices of using SiC Heaters Silicon Carbide Heating Element

1) In order to keep furnace temperature and the charges uniform of each element, before installation resistance distribution must be carried.

2) As the element is very brittle, be careful while install and maintain to avoid any damage.

3) When start to operate the furnace, raise voltage slowly and gradually, never give full load at one time.
