ABSTRACT:
A heating machine for heating an ingot of a metal such as a magnesium alloy. The heating machine has a heating chamber equipped with a RF induction coil capable of swinging about a horizontally axis. The coil is placed horizontally, and the metal ingot is fed into the coil from an introduction chamber by a pushrod. Stoppers prevent the ingot from falling from the RF induction coil when it is switched from its horizontal posture to its vertical posture. The coil is wound on a cylindrical member. A rotatable hollow shaft is firmly mounted to the holder in a perpendicular relation to a substantially axially central portion of the cylindrical member. A part of the coil is inserted in the hollow shaft via an insulating material. The rotatable hollow shaft is swung by a swinging mechanism. The induction heating coil is wound on a ceramic holder. A metal ingot is inserted in the holder with a given clearance. A plurality of pillars of L-shaped cross section are fitted over the holder to place it in position vertically and horizontally.
