Abstract

The invention relates to a levitation melting method and an apparatus for producing casting bodies with tilted induction units. During this method, induction units are employed in which the opposing ferrite poles with the induction coils are not arranged lying in one plane, but tilted at a determined angle to the levitation plane. In this way, an increase in efficiency of the induced magnetic field for melting the batches can be achieved with the induction units. The tilted arrangement increases the portion of the induced magnetic field that effectively contributes to the holding force of the field for levitation of the melt.
