induction heating steel cable for cutting

induction heating steel cable for cutting with radio frequency heating equipment

Objective Prior to cutting, heat a short section of a hardened steel cable coated with a polyethylene sheathing.
Material Multi-strand braided stainless steel cable 0.5 in. (1.27 cm) OD enclosed within a polyethylene sheathing
Temperature 1800 ºF (982) ºC
Frequency 240 kHz
Equipment • DW-UHF-20kW induction heating system, equipped with a remote workhead containing four (4) 1.0 μF capacitors (for a total of 1.0 μF).
• An induction heating coil designed and developed specifically for this application.
Process A three-turn helical coil is used to heat the cable in approximately 2 seconds. After the power is turned off, the heat is then transferred to the sheathing.
Results/Benefits Induction heating provides a quick, precise repeatable method to reach the high temperature required. It is a very efficient heating method.
