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.
