Continuous Induction annealing copper wires with High frequency heating system
Objective Continuously anneal a copper wire used in electric motors at aย rate of 16.4 yds (15m) per minute to eliminate work hardeningย caused during the drawing process.
Material Square copper wire 0.06โ (1.7mm) dia., temperature indicatingย paint
Temperature 842 ยบF (450 ยบC)
Frequency 300ย kHz
Equipment โข DW-UHF-60kW induction heating system, equipped with aย remote workhead containing eight 1.0ฮผF capacitors for aย total of 8.0ฮผF
โข An induction heating coil designed and developedย specifically for this application.
Process A twelve turn helical coil is used. A ceramic tube is placedย inside the coil to isolate the copper wire from the copper coilย 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)ย per minute.
Results/Benefits Induction heating provides:
โข Hands-free heating that involves no operator skill forย manufacturing
โข Flameless process
โข Ideal for in-line production processes
