Sic Element

SiC heating element
Silicon Carbide (SiC) heating element 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

Silicon Carbide Heating ElementDescription



Silicon Carbide Heating Element can be installed and replaced while the tin bath is operation. The heaters can be installed through the side-seal, or through the side of the bath roof, and are commonly used to extend campaign lives, where conventional elements in the side zones have been broken, and insufficient power is available.



Silicon Carbide Heating Element Advantages



High purity raw materials;

High structural density;

Slow aging;

Maximum temperature being up to 1500â?? (2732�°F);

Easy to be installed and replaced.



Types and Applications of Silicon Carbide Heating Element

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.

2. U-TYPE

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. W-TYPE

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.

U-L Shape MoSi2 Heating Elements

MoSi2 heating element can usually make use of furnace temperature from 1300C to 1900C. It is extensively used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacturer etc. It is an essential ideal element when the products are sintering in the high temperature.

MoSi2 heating element is a type of resistance heating element composed of high purity Molybdenum Disilicide.When heated toa high temperature in an oxidizing atmosphere,a layer of compact quartz qlass forms on the surface of the element which withstands oxidation.In an oxidizing atmosphere,its maximum temperature canreach1800 and its applicable temperature is 500~1700C. It can be widely used as heating elements in high temperature furnaces for a variety of industries including ceramics, magnets, glass metallurgy, refractory and many others.

W-shape MoSi2 Heating Element

Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of element owing to the high temperature combustion, which prevent MoSi2 from oxidizing more. When the element temperature is higher than 1700 C, the film becomes melting. It's not suitable for long time use in the temperature range of 400-700C, otherwise, the element will be powdering for the strong oxidation under low temperature.

High-temperature MoSi2 heating elements for all kinds of electric furnaces; Long service life, easy to replace, low maintenance cost; Old and new components can be used together; The solder joints are firm, have strong impact resistance, and are not easy to damage

Mosi2 electrical heating element
MoSi2 electrical-heating element is a resistance generate-heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and forms a light SiO2 glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1800f¦ during oxidizing atmosphere.
