COMPUTER MODELING OF INDUCTION THERMAL PROCESSING OF FERROUS AND NON-FERROUS ALLOYS

Computer simulation plays the critical role in the successful design of induction heating systems. In some cases, computer modeling is only remained option that designer has to design an induction system and determine on optimal process recipe. Mathematical modeling is also valuable tool when searching for root cause of failures. It helps to assess real-life factors including a deviation in dimensional tolerances, imperfections and presence of geometrical irregularities on sensitivity and robustness of technological process. Electromagnetic heating is a complex combination of circuit analysis, electromagnetics, heat transfer and metallurgical phenomena that are interrelated and highly non-linear because the physical properties of materials depend strongly on magnetic field intensity, temperature, chemical composition and microstructure. Various aspects related to specifics of numerical computer simulation of different induction heating and heat treating processes are briefly discussed in this presentation. Numerical case studies of solving a number of common induction heating and heat treating problems will be provided here.
