China Manufacturer Factory 3 Phases W Type High Power Silicon Carbide Heater Sic Heating Element Resistance Rod for Float Glass Tin Tank

Silicon carbide (SiC)  heating element/heater is made from quality green SiC powder, which was also added some additives according to the materials proportion. SiC heating elements are non-metallic products, they have a series of characteristics, such as higher temperature, antioxidation, anticorrosion, increase temperature fast, low coefficient of thermal expansion and so on. Therefore, they are widely used in various kinds of furnace with temperature 600C to 1600C. The max temperature can up to 1650⁰C . Silicon carbon heating elements have all kinds of specifications , super quality and lower price .our products have been well recognized in China . We are gaining market share overseas, such as USA , German ,france , Ialy ,Russia ,South  Korea , India ,Pakistan , brasil etc.
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.
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.

Silicon carbide (SiC)  heating element/heater:

Physical Property

Chemistry Property

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.

Electric Property
Silicon carbide (SiC)  heating element/heater has rather large specific resistance , when it is heated in air and the surface temperature of the hot zone reaches 1050ºC, it's resistance rate is 600-1400 mm2/mm (square millimetre , its resistance value changes as the temperature rises. From room-temperature to 800ºC is negative value , over 800ºC is positive value nature curve. 

Application of W-shaped Silicon Carbide Rods in Glass Tin Bath Industry
 
- Structural Advantage: The W-shaped silicon carbide rod features a "W"-shaped bent structure, which increases the heating area in a limited space compared to straight rods, enabling higher heating efficiency. It can be flexibly installed on the sidewalls or top of the tin bath, saving space during installation.

- Application Scenarios: It is mainly used in the edge heating or local temperature control areas of the glass tin bath, such as the inlet section (temperature compensation when the glass ribbon enters the tin bath), the outlet section (temperature adjustment before the glass ribbon cools down), or for heating the sealed edges of the tin bath to prevent glass deformation caused by excessively low edge temperatures.

- Advantages: The W-shaped structure can specifically heat the edges of the glass ribbon, avoiding insufficient temperature due to fast heat dissipation at the edges, ensuring uniform temperature of the entire glass ribbon. Meanwhile, the bent design facilitates adaptation to the complex spatial structure of the tin bath, making installation and maintenance more convenient.
