3.Description:

The 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, solid under high temperature and re-crystallized. compared with metal electric heating element, this kind of element is characterized by high-applied temperature, anti-oxidization, anti-corrosion, long service life ,little deformation ,easy installation and maintenance.

4.Electric property of SiC Heating Elements

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, its resistance rate is 600-1400mm2/mm, its resistance value changes as the temperature rises. From room-temperature to 800°C is negative value; over 800°C is positive value nature curve.

5.Recommend surface load

Furnace Temp (°c )	1100	1200	1300	1350	1400	1450
Surface load of hot zone (W/cm²)	<17	<13	<9	<7	<5	<4

6.Notes for using and installing the SiC heating element

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.

6. Silicon Carbide (SIC) heating elements is a non-metal electric heating element made from SiC as its main raw materials. It has some specific properties, such as low expansion coefficient, little deformation, stable chemical property, long service life, easy installation and maintenance, etc.

7. Usage: Silicon Carbide (SIC) heating elements 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.
