Modelling and Optimization Of Metal Induction Heating Prior Hot Forming And Heat Treatment

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 and temperature fields during induction heating of metallic workpieces will be discussed. The model has an interface adapted to optimization procedures. Optimization of temperature patterns and minimization of energy consumption are solved using unique alternance optimization method. Computational results for optimal heating of aluminum and steel cylindrical workpieces are shown as examples of practical applications of this modelling technology.
