Abstract
A molten metal feed apparatus which can feed molten metal into a casting apparatus by opening a vessel and which is free from leakage of the molten metal from the opening/closing part of the vessel, provided with a holding vessel having an opening at its bottom and holding a metal material, a lid for closing the opening, a drive means for making the lid move with respect to the holding vessel to open or close the opening, and an induction heating coil for heating the metal material by induction of a current to the metal material in the holding vessel and generating a magnetic field applying to the molten metal a force preventing leakage of the molten metal in the holding vessel from between the opening and the lid.
Claims10
A molten metal feed apparatus for feeding molten metal to a casting apparatus comprising:
- a holding vessel having an opening at its bottom and holding a metal material;
- a lid for closing said opening;
- a drive means for making said lid move with respect to said holding vessel to open or close said opening, and
- an induction heating coil for heating said metal material by induction of a current to the metal material in said vessel and generating a magnetic field applying to said molten metal a force preventing leakage of the molten metal in said holding vessel from between said opening and said lid.
