Abstract
The paper considers a process of induction heating of metallic billets prior to hot forming and heat treatment. The main goal of the presented research is a development of novel subject-oriented computer modeling strategy to optimize various induction heating operations using real-life quality criteria. Intricacies of interrelated nature of electromagnetic, temperature and thermal stresses fields during induction heating of metallic billets will be discussed. The model has an interface adapted to optimization procedures. Optimization of temperature patterns is solved using unique alternative optimization method. Computational results for optimal heating of steel cylindrical billets are shown as examples of practical applications of this modeling technology.
