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,silicided under high temperature and re-crystallized. Compared with metal electric heating element,this kind of element is characterized by high-applied temperature,anti-oxidization,easy installation and maintenance. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramice, powder metallurgy, glass metallurgy and machinery,etc.

We adopt new production process of cold ends so that our SiC heating elements have more excellent specific rate of heat zone resistance and cold end resistance, saving energy, long life, avoiding over-temperature of cold ends to damage the furnace body. 

Step 1

Indicate which type of element you need.

• Type: WDB

Step 2

Indicate the following dimensions identified in the element drawings above:

• Outer diameter: OD1, od2, mm

• Hot zone length: HZ, mm

• Cold end length: CZ, mm

• Overall length: OL, mm

• Shank Spacing: A, mm

• Bridge: D, mm

Note:  Element diameters are normally specified in millimeters.  Element dimensions may be specified in millimeters or inches.

Step 3

Indicate any other critical dimensions or tolerances if needed.

TYPE WDB THREE PHASE SiC elements in float glass production,are comprised of high purity, high density, silicon carbide grains, self bonded through recrystallization at elevated temperatures. Sintering at temperatures in excess of 2200ºC provides a structural density of 2.50 grams per cubiccentimeter. Such high structural density results in SiC elements of maximum strength and minimum porosity, with an extremely slow aging characteristic.Strength of the SiC elements is further enhanced by insertion of hot zones into oversized cold ends. Enlarged cold ends measure 28mm(1.10”) in diameter, accommodating hot zones of 19mm (0.75”) in diameter. Close tolerance sizing helps assure SiC elements fit to conventional roof construction. Leg to leg oncenter spacing is 52mm(2.05”). Overall element length is 647mm (25.47”). Length of hot zone is 265mm (10.43”). Height of bridge is 32mm (1.26”). Cold end length is 350mm (13.78”). The support 5.6mm (0.22”) hole is 44mm (1.73”) from the top of the cold end.
