• 2) MADYLAM, E. N. S. H. M. G., Institut National Polytechnique de Grenoble, 38402, Saint-Martin-d'Heres CEDEX, France.A theoretical analysis has been made to clarify the stability condition of Horizontal ElectroMagnetic Casting (HEMC) by means of the linear stability theory. The stabilities of thin plates and round rods of molten metal are analyzed when infinitesimal perturbations are added on the free surface of the levitated metal.Anisotropic influence of imposed magnetic field on the stabilization of perturbated surfaces is confirmed. A critical wave length which distinguishes stable condition from unstable one is 0.02 m for molten steel with the applied current density of 106 A/m2. This length practically limits the distance between a metal supply nozzle and the solidified part of the metal.
