Abstract :
This paper presents a numerical computation of a device for the horizontal casting of the inductive levitated metallic sheets. Local and integral magnitudes of electromagnetic field values are computed by means of FEM, using the FLUX-2D software and the dedicated program LEVITA. The influences of the supply frequency, magnetic saturation, and device configuration on the levitation force, induced power and transverse variation of the levitation force density are studied. Some experimental proof of the calculated magnitudes is also presented
