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 Stainless Steel Saw Blades
Objective: Induction Annealing saw blades used for cutting bread, prior to hole punching.
Material .38" (9.6mm) wide and .51" (12.9mm) wide continuous strips of 400 series stainless steel.
Temperature 600°C (315.6°F) for one second
Equipment • DW-UHF-6KW induction heating system equipped with a remote workhead containing one 1.00 μF capacitor. • An induction heating coil designed and developed specifically for this application.
Process A three turn helical coil at a 45º angle is used to anneal a 1.2" (30.5mm) strip of saw blade prior to hole punching.
Results/Benefits Induction heating provides: • Improved quality of blades at hole punching location • Decreased scrap product • Easily incorporated into existing production lines
