The silicon carbide heating element is a kind of non-metal
rod or tube shape high temperature electric heating
element. It is made of selected super purity green
hexagonal silicon carbide as main material, which is made
into blank and silicon crystal under high temperature of
2400ºC. In oxidizing atmosphere, its service temperature
can reach 1450°C and continuous use life can reach 2000
hours.
Type: we have rod, u, w, h, gun, single spiral, double spiral, dumbbell, door like type
Size:
2. Heating Zone Lengh (HZ )
3. Cold Zone Lengh(CZ)
4. Overall Length (OL)
5. Resistance you need.
Order Sample: U-type, HZ200mm, CZ150mm, OL350mm, Resistance
0.4ohms
1. High strength and excellent shock resistance;
2. Heat source is free of noise and air
pollution;
3. Anti-oxidization; 4. Anti-corrosion, 5. Long service
life
6. Little deformation, 7. Easy installation and
maintenance.
8. Excellent specific rate of heat zone resistance and cold
end resistance,
9. Avoiding over-temperature of cold ends to damage the
furnace body. 10. Saving energy
Silicon Carbides are used in applications ranging in temperature from 600°C up to 1400°C in both air and controlled atmospheres. the type of atmosphere used will determine the maximum recommended element temperature. This kind of silicon carbide elements can be mounted either vertically or horizontally.
U shape Silicon Carbide is consists of two silicon carbide rod with same diameter. Each rod has both hot zone and cold end with identical resistance. Two rods are connected by the low resistance SiC. Also the connector could be used as holder according to different requirements.
3-phase elements are available in 2 different types:
SGC (Dumbbell), SGD(Standard).
These elements are self-bonded silicon carbide formed
by re-crystallization of silicon carbide at high
temperature. It consists of three high-purity silicon
carbide rods connected at one end by a silicon carbide
crossbar.
==Silicon carbide Uses==
1.As the use of silicon carbide, high temperature, high
temperature, anti-oxidation, corrosion-resistant, fast
heating, long life, high temperature deformation, easy
installation and maintenance features. Good chemical
stability. .
2.Hard and brittle texture components, thermal shock
resistance, high temperature deformation is not
easy
3. Silicon carbide has good chemical stability, strong acid
resistance. Its aggressive alkaline substance at elevated
temperature conditions.
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
assembling 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 one should follow the increasing
resistance. If many are damaged or resistance increased too
much, heater should be changed.
