摘要：Metal is melted in an induction-heated crucible (13) on which a mold (10) with adownward-facing filling opening (26) is located in the melting position. After melting themetal, 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 themold (10). In order to melt reactive metals, melting is done in a crucible (13) that issurrounded by a vacuum, this crucible being surrounded by an induction coil (15) outsideof the vacuum. The mold (10) is located in a vacuum-sealed casting chamber (6) which isevacuated together with the crucible (13) prior to melting and casting is carried out by ajoint tilting of the crucible (13), casting chamber (6) and mold (10) by at least 180 degreeswhile the vacuum is maintained.
