Study on the Distributed Parameter Model of the Billet Induction Heating Process Based on the Finite Difference Method

In this paper a distributed parameter model of the continuous casting billet induction heating process is established. It uses the finite difference method to solve the two-dimensional temperature field of the billet cross-section, predicts the variation of the billet temperature distribution during heating, and verifies the results with ANSYS finite element simulation data. The results show that this method can achieve high prediction accuracy, and is helpful to achieve precise control of the billet temperature in induction heating process.
