Finite element analysis for inductive reheating process of continuously cast steel billets

Abstract

Inductive heating has distinctive advantages for reheating of billets in continuous casting, but the success of this process requires good understanding of the operation principles and effective control of the process variables. In the present study modelling and finite element simulation are performed for the inductive reheating of continuously cast square billets. Important performance characteristics such as temperature profile, magnetic field distribution and the power absorption have been analysed. Representative temperatures obtained from the simulation are compared with experimentally measured temperatures. The results provide better understanding of the inductive reheating process and key information for process design.
