DB Dumbbell Type Silicon Carbide(SiC)Heating Elements Rods

General Description

The silicon carbide (SiC) heating elements rod is a kind of non-metal high temperature electrical resistant heating element. It is made of super quality green silicon carbide, which is made into blank, solid rod under high temperature and re-crystallized. Compared with metal electrical heating elements, this element takes advantages of high-applied temperature, anti-oxidization, anti-corrosion, long service life, little deformation, easy installation and maintenance. Therefore, it is widely used in various high temperature electric furnaces/oven/kilns for laboratory use or industrial use and other industrial heating devices, such as in the industries of magnet, ceramics, powder metallurgy, glass, metallurgy and machinery etc.
