Finite Element Analysis of Continuous Induction Reheating of Hot Steel Long Products

This paper deals with the study of induction reheating of long steel products starting from an initial temperature of around 700 Celsius degrees,based on finite element models.Two industrial innovative technologies are considered:reheating of hot billets between the continuous casting lines and the rolling mill facilities and reheating of steel rails before quenching,if the rail upper side hardening is included in the rolling mill facilities.The finite element analysis of coupled electromagnetic and thermal phenomena takes into account the dependences on temperature of electromagnetic and thermal properties of steel.
