Zusammenfassung:Metal is melted in an induction-heated crucible (13) on which a mold (10) with a downward-facing filling opening (26) is located in the melting position. After melting the metal, the crucible (13) and the mold (10) are jointly rotated about a horizontal axis (A-A) into a tilting position in which the molten material flows from the crucible (13) into the mold (10). In order to melt reactive metals, melting is done in a crucible (13) that is surrounded by a vacuum, this crucible being surrounded by an induction coil (15) outside of the vacuum. The mold (10) is located in a vacuum-sealed casting chamber (6) which is evacuated together with the crucible (13) prior to melting and casting is carried out by a joint tilting of the crucible (13), casting chamber (6) and mold (10) by at least 180 degrees while the vacuum is maintained.
