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.

Levitation melting method using movable induction units

A method for producing cast items in a casting method, wherein a charge of a conductive material is introduced into the sphere of influence of at least one alternating electromagnetic field, so that the charge is kept in a levitating state. The melt is poured into moulds in order to produce turbine blades, prostheses or turbocharger impellers.
