induction heating service,induction heater,induction heating equipment and induction heating system are supplied by DaWei Induction Heating Machine Co.,Ltd
Induction heating is a form of non-contact heating for conductive materials, when alternating current flows in the induced coil, varying electromagnetic field is set up around the coil, circulating current(induced, current, eddy current) is generated in the workpiece(conductive material), heat is produced as the eddy current flows against the resitivity of the material.
Induction heating is a rapid ,clean, non-polluting heating form which can be used to heat metals or change the conductive material’s properties. The coil itself does not get hot and the heating effect is under controlled. The solid state transistor technology has made induction heating much easier,cost-effective heating for applications including soldering and induction brazing ,induction heat treating, induction melting,induction forging etc.<
Induction Annealing Brazing Wire
Objective: Induction Annealing a brazing wire for preform production.
Material: Copper Nickel Silver 2774 Alloy rod 0.070" (1.8mm) diameter.
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
