• Resumen

  • This paper presents the numerical modeling (using the Finite DifferenceMethod-FDM, and Finite ElementMethod- FEM) of the electromagnetic and thermal fields in a steel piece heated up inside an induction crucible furnace, and the experimental validations. Both modelings have been validated experimentally, so they can be used in designing the equipments and in the numerical control of induction heating process. The program based on FDM can be used in the first stage of designing due to the reduced CPU time. In this stage the inductor parameters and heating time can be estimated, and a study of the influence of diverse factors upon the heating process can be achieved.

    The FLUX 2D program can be used in the optimization stage, because it allows a more thorough analysis of the phenomena.
