Abstract
A crucible (9) surrounded by an induction coil (10) is housed for tilting about a first tilt axis within a gas-tight furnace chamber (2) which has a closable opening (40a) for transferring the melt (31) into a receiving vessel (36, 63). The furnace chamber (2) is in turn tiltable about a second tilt axis (A2) between a melting position and a position in which the start of the pouring of the melt is immediately imminent by an angle which corresponds to the range of the tilting angle of the crucible (9). The opening (40a) for transferring the melt is surrounded by a first sealing flange (41) which, after the tilting path of the furnace chamber (2) has been traveled, comes sealingly into contact with a second sealing flange (38, 64) of an additional gas-tight chamber (35, 61) in which the receiving vessel (36, 63) for the melt is situated.
