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

摘要

Computer simulation plays a critical role in the successful design of induction heating and heat treating systems. In fact, in some cases, computer simulation is the only remaining option that is available to an engineer in the design of an induction heating system and the determination of optimal process parameters. Computer simulation is also a valuable tool when searching for root cause of failures; it can help to assess how real-life factors such as deviations in dimensional tolerances and geometric irregularities affect the sensitivity and robustness of a process. Induction heating incorporates a complex combination of electromagnetics, heat transfer, circuit analysis, and metallurgical phenomena that are interrelated and highly non-linear due to material properties' dependence upon magnetic field intensity, temperature, chemical composition, microstructure, etc. Various aspects of numerical computer simulation of different induction heating and heat treating processes are discussed in this presentation and a number of common induction heating and heat treating problems are addressed in the form of real-life case studies.
