Product Introduction
Silicon carbide rods, also known as silicon carbide heating element is the use of high-quality green silicon carbide as the main raw material, the processing system also, high-temperature silicification, recrystallization of rod-shaped non-metallic high-temperature heating components. Compared with the metal heating element, silicon carbon rod has the characteristics of high temperature, anti-oxidation, corrosion resistance, long life, small deformation, easy installation and maintenance. Therefore, silicon carbon rods are widely used in magnetic materials, powder metallurgy, ceramics, glass, metallurgical and mechanical industries such as a variety of high-temperature electric furnace and other electric heating equipment. The ED type is the standard SiC heating element. A high-density self-bonded silicon carbide element, ED type is available in a large range of diameters and lengths.

Specification
Spark MS18L MoSi2 Heating Element
1. High temperature MoSi2 heating element for various electric furnaces.
2. Max. working temperature 1730℃ ( 3346°F )
3. Compact protective layer of quartz glass
4. Long life combined with ease of replacing failed elements contributes to a high degree of utilization of the furnace and low maintenance costs.
5. New and old elements can be connected in series
6. Can be used continuously or intermittently
Advantage
1. Elements have the capabilities to resistance to oxidation and automatically repair, suitable for continued using in any kinds of oxidizing atmospheres.
2. Elements are shaped in hot-working process, which keeps the base material in good tenacity and plasticity at high temperatures. The geometrical figure, standard and dimension is canonical, may produce any special shape and any dimension to meet the customer requirement.
3. Because of the special technology, welding spot is fast and shock resistance, which dramatically reduced the damaged probability of welding spot by electric current, as well as transit and installation.
4. High density of Spark MoSi2 Heating Elements increases its electrical conductivity. The characters of faster warming and power consumption low, which reduce production cost.
5. Good appearance quality and tenacity, high mechanical strength.
6. Adopt special technology, heaters come with compact protective layer, excellent performance in no-oxidizing atmosphere electric furnaces.
