The connection methods of silicon carbide heater rods
Silicon carbide heater rods are a kind of electrode material commonly used in electric arc furnaces and induction furnaces. There are several connection methods as follows:
Direct welding
The silicon carbide heater rod and the conductor wire are directly welded together, which is simple and easy, but attention should be paid to the welding quality and contact area.

Sprial connection
The spiral silicon carbide heater rod is connected by insulating ceramic, clamp, stainless steel clamp, which can be disassembled and replaced conveniently.

Clamp-type connection
The silicon carbide heater rod and the cable are clamped in the clamp respectively, and fastened by bolts, which can be disassembled and suitable for occasions where electrodes are frequently replaced.

Different Types of Silicon Carbide Rod Clamps:
Stainless steel G clamps
Stainless steel C clamps
Stainless steel M type terminal clamps
Spring-type connection
The silicon carbide heater rod and the cable are inserted into the spring respectively, and fixed by elastic force, which can be disassembled and suitable for low-current occasions.
These are the common connection methods of silicon carbide heater rods, and the specific choice should be based on the actual situation, such as, type Globar silicon carbide heating element used for float glass.
