Continuous Induction annealing copper wires with High frequency heating system
Objective Continuously anneal a copper wire used in electric motors at aĀ rate of 16.4 yds (15m) per minute to eliminate work hardeningĀ caused during the drawing process.
Material Square copper wire 0.06ā (1.7mm) dia., temperature indicatingĀ paint
Temperature 842 ĀŗF (450 ĀŗC)
Frequency 300Ā kHz
Equipment ā¢ DW-UHF-60kW induction heating system, equipped with aĀ remote workhead containing eight 1.0Ī¼F capacitors for aĀ total of 8.0Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A twelve turn helical coil is used. A ceramic tube is placedĀ inside the coil to isolate the copper wire from the copper coilĀ and to allow the copper wire to flow smoothly through the coil.
Power runs continuously to anneal at a rate of 16.4 yds (15m)Ā per minute.
Results/Benefits Induction heating provides:
ā¢ Hands-free heating that involves no operator skill forĀ manufacturing
ā¢ Flameless process
ā¢ Ideal for in-line production processes
