Abstract

The invention concerns an appliance for moulding parts made of very reactive metal or mixture of metals, comprising, inside a vacuum chamber (15) a cold induction-heated crucible (1) whereof the base comprises a removable sectored plug (6), said crucible being configured to enable the levitation of said metal or mixture of metal in smelted state (5); a mould (20) provided under the crucible (1);
means for driving the mould in rotation; and outside the chamber, a coil (13) arranged at the lower part of the crucible is designed to heat by induction said metal or said mixture.
