Silicon Carbide High Temperature Electric Heating Element Silicon Carbide Rod 1450 ℃ Heating Element
Brief description of silicon carbide heating element:
Silicon carbide rod (SiC) electric heating element is a rod-shaped non-metallic high-temperature electric heating element made of green high-purity hexagonal silicon carbide as the main raw material, processed into embryo, silicified at high temperature and recrystallized at 2200 ℃. The surface temperature of the rod can reach 1550 ℃.
Advantages of silicon carbide electric heating element:
1. The silicon carbide rod is hard and brittle, has a small expansion coefficient, good cold and heat resistance, and is not easy to deform,
2. Good chemical stability, strong acid resistance, no reaction with strong acid.
3. Strong heat dissipation and accurate temperature control

Corresponding product uses of different types of silicon carbide rods:
1. Equal diameter silicon carbide rod: equal diameter silicon carbide rod (GD type) is a substitute for thick end silicon carbide rod, which has the advantages of small end resistance, long service life and energy saving:
It is commonly used in rare earth phosphors, electronics, magnetic materials, powder metallurgy, precision casting and other industries as heating elements for pusher furnaces, mesh belt furnaces, trolley furnaces and box furnaces.
2. Gable silicon carbide rod: gable silicon carbide rod (GDS type) is mainly used in float glass tin bath, optical glass melting, glass deep processing, controlled atmosphere electric furnace, etc.
3. U-shaped silicon carbide rod: U-shaped silicon carbide rod (GDC type): used in kilns requiring single terminal wiring, commonly used in pusher furnaces, trolley furnaces, box furnaces and other periodic electric furnaces.
