1. Thick and short silicon carbide rods (GC type) are often used in old-fashioned heat treatment furnaces, experimental furnaces, tunnel furnaces, etc.
2. Equal diameter silicon carbide rod (GD type) is a substitute for thick end silicon carbide rod
It can be used as heating element for push plate furnace, mesh belt furnace, trolley furnace and box furnace.
3. Mountain-shaped silicon carbon rod (GDS type) is mainly used in float glass tin bath, optical glass melting, glass deep processing, controlled atmosphere electric furnace, etc.
4. U-shaped silicon carbide rod (GDC type): used in furnaces requiring single-ended wiring, commonly used in push-plate furnaces, trolley furnaces, box furnaces and other periodic electric furnaces.
5. Door type silicon carbide rod (GDC type): suitable for heating at the bottom or both sides of large box furnaces and trolley furnaces
6. H-type silicon carbide rod (GDH type): It is often used in the heating and heat preservation of the feeding channel and the material basin in the glass industry.
7. Gun-shaped silicon carbide rod: suitable for the material basin for processing glass products.
8. Slotted silicon carbide rod: used for heating and heat preservation of molten aluminum and zinc.
9. Special-shaped silicon carbide rods: mainly used in crucible aluminum melting furnaces
