Product Description



Silicon carbide electric heating element is the selection of high-quality green silicon carbide as the main raw material, processed billet, high temperature silicification, recrystallization and rods of non-metallic high temperature electric heating element, compared with metal electric heating element, with the use of high temperature, oxidation resistance, corrosion resistance, long life and easy installation and maintenance characteristics, so it is widely used in magnetic materials, powder metallurgy, ceramics, ceramics, etc. A variety of high-temperature electric furnaces and other electric heating equipment in the glass and machinery industries

We adopt a new hot-cold end production process, with excellent hot-cold end resistance ratio, energy saving, long life, while avoiding the damage caused by excessive temperature of the cold end to the furnace body


Advantage

Compared with metal electric heating element, this kind of element is characterized by high-applied temperature, anti-oxidization, anti-corrosion, long service life, little deformation, easy installation.

Application

It is widely used in various high temperature electric furnacesand other electric heating devices, such as in the industries of magnet, ceramics, powder metallurgy, glass, metallurgy and machinery, etc.

Our Feature

We adopt new production process of cold ends, so our SIC heating elements have 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.

Chemistry Property

1.Antioxidation Property of Elements

The element start to being oxidized when heat to 800°C in air, and a SiO protect film will be generated in surface of hot zone when temperature get to 1000-1300°C ; cristobalite will be crystallized at 1300°C; the protect film get to a certain thickness when the temperature get go 1500°C which make the oxidation speed being very slowly to stable. if continue to heat to over 1627°C ,the protect film will be damaged and oxidation speed will be more rapid evidently and make the element damaged earlier.
Thought the element will be oxidized very slowly in course of application, it also will make the resistance increased following long time application, this phenonenon calls ageing , in order to lower the ageing speed, we use special technology to spread a protect film on the surface of hot zone in the 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 to elements.

The alkali and alkaline metal oxide will react with SiC at about 1300°C and generate silicate, which calls alkali-chemical corrosion, and can influence the glowing of element. 

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.
