Abstract (en)
[origin: WO2019202111A1] The invention relates to a method for producing cast bodies in a levitation melting process, wherein a charge of an electrically conductive material is brought, by means of a starting material which has multiple preseparated charges separated by regions with a reduced cross-section, into the reach of at least one alternating electromagnetic field so that the charge is held in a state of levitation. The regions are designed in such a way that the preseparated charges are not detached until during the melting process in an alternating electromagnetic field. The molten metal is then cast into casting molds.
