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 (SiC) electric heating elements for element temperatures up to 1625 available in a wide variety of standard sizes and geometries, or in customized designs to meet the specific needs of various processes and equipment.

SiC heating elements are capable of high power output, and may be mounted either vertically or horizontally. Because the element material remains rigid even at the maximum operating temperatures, no special supports are required, which simplifies the design of the equipment.

SCR Type SiC Heating Elements

Product Description

SCR(SGR, SEU) type double-spiral silicon carbide heating elements are cut so as to place both electrical terminations on the same end of the element.They are supplied with the terminal assembly attached. SGR (SCR) type Torch Furnace silicon carbide design or dimensions preclude wiring from both sides of the furnace. This type is ideal for blind holes and the operating temperature can be up to 1500 deg C.

it is also widely used in various high temperature electric furnaces and other electric heating debices, such as in the industrial of magnet, ceramics, powder metallurgy, glass, metallurgy and michinery etc.

Features:

1, High temperature resistance, resistance to oxidation and corrosion

2, Fast heating, long life, small deformation at high temperature, easy to install and maintain

3, With automatic electronic control systems, precision constant temperature can be obtained, curve temperature control can be obtained too according to the needs of production

DB ( Dumbbell ) Type Silicon Carbide Heating Element

Silicon carbide (SiC) 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 2400�ºC. In oxidizing atmosphere, its service temperature can reach 1450�°C and continuous use life can reach 2000 hours.

The Dumbbell style elements, with the enlarged cold ends, were one of the earliest designs of the heating elements, which were originally made oversized to increase the cold end cross section, lowering electrical resistance so as to lower the operating temperature of the cold ends. Modern Dumbbell elements, by contrast, all employ an advanced technology to keep the terminal ends cool by virtue of the decreased resistivity of the lower resistance of the material of the cold ends in the manufacturing process. Therefore, oversized cold ends are no longer necessary. Non-dumbbell or ED type elements can substituted for Dumbbell elements.

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.
