Product Description

Silicon Carbide Heating Element

 

Description

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, silided under high temperature and re-crystallized.

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.

Product Parameters

Physical Property

 
High Quality Resistor Sic Heating Element Furnace Spare Parts

The linear expansion coefficient, heat conductivity and specific heat of element will change along with temperature change. And the relational data are the follows:

Chemistry Property
 

1. Anti-oxidation Property of Elements

The element start to being oxixdized 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 thinckness when the temperature get to 1500°C which make the oxidation speed being very slow 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.
Though the element will be oxidized very slowly in course of application, it also will make the resistance increased following long time application, this phenomenion 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.

 

Electric Property

SiC heating elements have rather large specific resistance, when it is heated in air and the surface temperature of the hot zone reaches 1050°C, it's resistance rate is 600-1400mm2/mm, its resistance value changes as the temperature rises. From room-temperature to 800°C is negative value, over 800°C is positive value.
