Abstract (en)
[origin: WO2020016062A1] The invention relates to a levitation melting method and a device for producing cast bodies using an annular element made of a conductive material for introducing the casting of a molten batch into a casting mold. In the method, the annular element is introduced into the region of the electromagnetic alternating field between the induction coils in order to cast the molten batch, and the molten metal thus drains into the casting mold in a controlled manner by influencing the induced magnetic field.
