Understanding the Induction Hardening Circuit

Heat treating power supplies, transformers, capacitors and inductors function as an induction electrical circuit. This electrical circuit controls the power and frequency delivered during the induction hardening process. Other non-electrical elements function as part of this circuit including: the material handling unit and the quench system. This presentation will demonstrate a typical induction scanning operation from set-up to a finished sectioned part. An explanation of this circuit will be discussed in an easy to comprehend non-technical format. Fundamentals of the different components of this system will be covered including an explanation of how the process parameters of frequency and power are determined.
