Silicon Carbide Heater High Temperature Heating Elements
Sic Heating Elements General Description
Sic Heating Elements is a kind of non-mental high temperature electric heating element.It is made of selected high-purity green silicon carbide as raw material which is made into blank and silicon crystal under high temperature of 2400ºC. It can usually make use for furnance which temperature from 600C-1600ºC. It is widely used in various electric heating element of glass,chemical, electronic material and so on.
Types of Sic Heating Elements:
1. SW (Standard)
SW Silicon Carbides are used in applications ranging in temperature from 600°C up to 1400°C in both air and controlled atmospheres. Although 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. SGC elements are designed for vertical installation in standard float glass bathes and SGD elements for horizontal installation. They can be connected directly on three-phase power supply and is a one-side terminal type which permits drawing out the terminals from the roof of the furnace.
4. Single Spiral Silicon Carbide and Double Spiral Silicon Carbide:
They are made from silicon Carbide powder, and have two shapes: single and double sprial silicon carbide heating element. They are widely used in all kinds of kilns and furnaces.
Recommended surface load and Influences to Surfaces of the Elements in Different Operating TemperatureS
|atmosphere||Furnace Temperature(°C)||Surface Load(W/cm2)||The influence on the Rod|
|Ammonia||1290||3.8||The action on SiC produces methane and destroys the protection film of SiO2|
|Carbon dioxide||1450||3.1||Corrode SiC|
|Carbon monoxide||1370||3.8||Absorb carbon powder and influence the protection film of SiO2|
|Halogen||704||3.8||Corrode SiC and destroy the protection film of SiO2|
|Hydrogen||1290||3.1||The action on SiC produces methane and destroys the protection film of SiO2|
|Nitrogen||1370||3.1||The action on SiC produces insulating layer of silicon nitride|
|silicon dioxide||1310||3.8||Corrode SiC|
|Water-vapor||1090-1370||3.1-3.6||The action on SiC produces hydrate of silicon|
|Hydrocarbon||1370||3.1||Absorb carbon powder resulted in Hot pollution
Sic Heating Elements Features
Notice 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 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.
