Induction Wire Heating Process Applications

Induction Wire Heating Process Applications In the production of steel wire, copper wire, brass wire, and steel or heating copper spring rods, different heat treatment processes are used, such as wire drawing, tempering after production, quenching heat treatment in special requirements, induction annealing before use as raw material, etc. There are a lot of requests … Read more

Induction Annealing Copper Wire

Induction Annealing Copper Wire

Objective: Induction Annealing a brazing copper wire for preform production.

Material: Copper Nickel Silver 2774 Alloy rod 0.070″ (1.8mm) diameter.

Temperature 650ºF(343.3ºC)

Frequency 580 kHz

Equipment: • DW-UHF-6kW-III induction heating system equipped with a remote workhead with one 1.0 μF capacitor, and a 4-20 mA input controller to aid in voltage ramping. • An induction heating coil 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 650ºF (343.3ºC) for annealing.

Results/Benefits Induction heating provides: • Higher productivity of 27′ (8.2m) per minute • Reduction in surface oxidation & scaling • Consistent, repeatable results
