Abstract: The invention relates to a method for producing casting bodies in a levitation melting method in which a batch of an electrically conductive material is brought into the sphere of influence of at least one alternating electromagnetic field by means of a starting material having a plurality of pre-separated batches separated by regions of reduced cross-section so that the batch is kept in a state of levitation. The regions are designed in such a way that separation of the pre-separated batches takes place only during melting in an alternating electromagnetic field. The melt is then cast into casting moulds.

Abstract: The invention relates to a levitation melting process and an apparatus for producing castings comprising a ring-shaped element of a conductive material for introducing the casting of a molten batch into a casting mould. In the process, the ring-shaped element is introduced into the region of the alternating electromagnetic field between the induction coils in order to cast the molten batch, thereby initiating a targeted run-off of the melt into the casting mould by influencing the induced magnetic field.

Abstract: The invention relates to a levitation melting process and a device for producing castings with movable induction units. In this process, induction units are used in which the opposite ferrite poles with the induction coils are movable and move in opposite directions. In this way, the induction units for melting the batches can be arranged close together in order to increase the efficiency of the induced magnetic field. When casting the molten batch, the induced magnetic field is reduced by increasing the distance between the ferrite poles with the induction coils, thus preventing the melt from touching the ferrite poles or the induction coils.

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.
