Induction Heating Non-Ferrous Metals: Physical Characteristics & Process Optimization

While the induction heating of non-ferrous alloys is fundamentally no different than that of other metals, the unique physical properties of different non-ferrous alloys have a number of critical induction heating implications.  This paper addresses a number of physical characteristics and practical subtleties associated with the induction heating of non-ferrous alloys, focusing particularly on the influence of electromagnetic and thermal material properties.  A mathematical optimization routine for continuous induction heating processes is also presented.  Utilizing coupled electromagnetic-thermal FEA computer simulation results and taking into account real-world process requirements, this routine is used to maximize induction heating quality and equipment performance.
