Annealing Saw Blades with Induction

Induction Annealing 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

Frequency 589kHz

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
