Hot selling industrial furnace sd silicon carbid heat elements
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, anti-corrosion, long service lige, little deformation, easy installation and maintenance.
- 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.

1.Antioxidant property of elements Sd silicon carbid heat elements
Though the element will bo oxidized very slowly in course of application, it also will make the resistance increased following long time application,this phenomenon calls aging.
In order to lower the aging speed, we use special technology to coat a protect film on the surface of hot zone in th course of production, which enhance the antioxidant property of element evidently and lengthen the service life.
2.The effects of alkali and alkaline metal oxide ot elements
The alkali and alkaline metal oxide will react with sic at about 1300 ℃ and generate silicate, which calls alkali-chemical corrosion, and can influence the glowing of element evidently.
3.The effects to elements from melting metal
Some metals, such as cobalt, nickel, chrome and so on, can corrade the element in high temperature melting state and affect the service life of element.
