Induction Annealing Copper Wire
Objective:Ā Induction Annealing a brazing copperĀ wireĀ for preform production.
Material: Copper Nickel Silver 2774 Alloy rod 0.070″ (1.8mm) diameter.
Temperature 650ĀŗF(343.3ĀŗC)
Frequency 580 kHz
Equipment: ā¢Ā DW-UHF-6kW-III induction heating systemĀ equipped with a remote workhead with one 1.0 Ī¼F capacitor, and a 4-20 mA input controller to aid in voltage ramping. ā¢ AnĀ induction heating coilĀ designed and developed specifically for this application.
Process A unique helical coil consisting of four consecutive coils connected in parallel with a quartz tube lining is used to heat the wire to 650ĀŗF (343.3ĀŗC) for annealing.
Results/BenefitsĀ Induction heatingĀ provides: ā¢ Higher productivity of 27′ (8.2m) per minute ā¢ Reduction in surface oxidation & scaling ā¢ Consistent, repeatable results
