AFRC_CATP_1412 - INDUCTION HEATING SYSTEM UPGRADE

Introduction & Context Induction heating (IH) is used in many applications such as: surface hardening, pre-heating for forging/forming, assembly processes, metal/alloy fusion, etc. The primary attraction of this technology is that it offers relatively fast heating rates and due to its direct nature there is little loss of energy in raising the temperature of refractories or other extraneous objects. Thus, if it is applicable it represents an extremely cost effective method of heating.

Although IH systems have reached certain maturity, there are still some issues to address in order to further increase its performance, notably for non-axisymmetric geometries and for controlling the temperature gradient in the work piece.

By its nature, induction heating (as well as Resistance Spot Welders, Plasma cutters, MIG Welders) can emit moderate level of EMF so this aspect HSE must also be considered and if possible reduced by putting protection in place.

The current FEA model partially developed in CORD 1137 will also be used and improved for dynamic induction heating testing.
