The paper presents an iterative numerical approach for computing the rise and distribution of temperature inside cylindrical steel billets subjected to a variable electromagnetic field. The billet is divided into a number of concentric cylindrical elements. A step-by-step solution is used to compute the temperature rise caused by induced power. The billet physical properties, such as resistivity and thermal conductivity versus temperature, are included in the model. Values at any temperature are obtained by numerical interpolation between adjacent points given in the table. The heat losses to the boundary and heat transfer between adjacent elements are included. Good estimates of the heating time and heat homogeneity inside the billet are obtained in comparison with available data in the literature.
Induction heating is widely used in industry for different purposes such as surface hardening, annealing, forging and melting of metals.
