factory Manufacturer W-shaped SiC silicon carbon rod electric factory industry best price heater heating element, special-shaped heating rod for rapid heating
Silicon Carbide Heating Element is a kind of non-mental high temperature electric heating element.It is made of selected high-purity green silicon carbide as raw material which is made into blank and silicon crystal under high temperature of 2400ºC. It can usually make use for furnance which temperature from 600C-1600ºC. It is widely used in various electric heating element of glass, chemical, electronic material and so on.
Feature:
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

1.Antioxidation Property of Elements
The element start to being oxidized when heat to 800°C in air, and a SiO2 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.
