Simulation of induction heating of slabs using ELTA 6.0


This presentation is devoted to simulation of slab heating in the longitudinal magnetic field. There were many studies of this technology in the past, but they were mainly related to heating materials with linear properties. One of the problems in slab heating simulation is a 3D character of the electromagnetic (EM) and thermal (T) processes. New program ELTA 6.0 has an option of 2D FDM simulation of EM and T processes in combination with semi-analytical account for the finite length of the system. Presentation contains a short survey of history and state-of-art of slab heating. New simulation procedure and a study of the edge effect variation during high temperature heating of the magnetic slab are presented. Example of simulation for multi-stage heating of big steel slab illustrates the theoretical considerations. (Full text)
