             Super quality 600~1600C U W ED DB TYPE SiC silicon carbide heating element

 

Product Description

 

Silicon carbide,operating temperature is very high, so it is high temperature resistance, anti-oxidation,

 

corrosion-resistant, fast heating, long life, high temperature deformation, easy installation and maintenance, and good chemical stability.

 

Electronic control systems and automation facilities, get an accurate constant temperature, and can automatically 

 

adjust temperature,according to the manufacturing technique . Silicon carbide heating convenient, safe 

 

and reliable

 

 

 

Non-metallic silicon carbide heating element is use of high-purity green hexagonal silicon carbide as the main 

 

raw material, 2200 °C high temperature recrystallization become rod, tube type non-metal high temperature 

 

electric heating elements.The normal temperature up to 1600°C, if it is fair use , service time will more than 

 

2000 hours.In the air, without any protective atmosphere. Suitable for a variety of electric furnace electric kiln.

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: heater silicon carbide sic heating elements 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 heater silicon carbide sic heating elements.

 

Heater silicon carbide sic heating elements 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.

1)Our products can be customized according to customer requirements.

2)Notes for using and installing the heater:

3)Heater should be protected againest damp during storing or installing to ensure the performance of the henter.

4)In order to be sure of well-distributed lod of each and groups heater shoud be divided before assembling. The tolerance of the resistance of each one can not exceed by 10% each other.

5)Heater is hard and brittle, please be careful when assem bling and maintaining so as to avoid damage.

6)When operating the electric furnace at the beginning, the voltage should be increased slowly and can not be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater.

7)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, akk heater should be changed.
