Induction Annealing Saw Blades


Induction Annealing Saw Blades With RF Heating System

Objective Anneal 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 400kHz
Equipment • DW-UHF-6kW-III 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
