In rolling systems with direct transmission it is strongly desired that the temperature distribution of the metal billet is uniform. For that purpose, an optimal induction heating system must be developed. In this paper, a new 2D simulation system for analysis of magneto-thermal coupled problem inside the billet is presented. This system comprises two main routines: 2D edge-based finite element analysis for eddy current computation and 2D non-liner node-based finite element analysis for thermal field computation. The proposed system includes the influence of the billet's movement and temperature changes in the moving direction that is perpendicular to the analysis field, providing accurate quasi-3D computation. The obtained results show very good agreement with previously computed results using 3D simulation system with significantly less computational cost.
