ABSTRACT:
A crucible 2 for holding a molten metal 1 is stored in a crucible chamber 5 which comprises a lid 3 and a chamber body 4 connected airtightly to each other. In the lid 3, there are provided an openable/closable molten metal supply opening 6 through which a cold metal charge is thrown in and a molten metal is received from a melting furnace, and a pipe-shaped stoke 7 which extends through the lid 3 and rises from the bottom portion of the crucible 2. The stoke 7 includes on the top end portion thereof a joint 9 which can be connected to a metal mold 8. To the crucible chamber 5, there are connected a pressure pipe 10 which is used to apply pressure to the crucible chamber 5 to thereby pour the molten metal to a metal mold, and an exhaust pipe 11 which is used to discharge the air of the crucible chamber 5 therefrom to thereby stop the pouring of the molten metal. In the outer periphery of the crucible 2, there is provided an induction heating device 14 which comprises a coil 12 wound round the crucible 2 and a plurality of yokes 13 disposed in the circumferential direction of the outer periphery of the crucible 2.
