摘要： An apparatus for heating molten metal including a ladle provided with a refractory heat insulating material and first core members arranged in pairs and attached to the outside of the ladle. A tray capable of mounting said ladle carries second cores with magnetic pole portions at both ends of said so as to face the ladle mounted first cores. A coil if provided for exciting the second cores. The first cores and magnetic pole portions of second cores are located at the outer circumferential portion of the ladle to face each other radially in a manner to facilitate placement and removal of the ladle to and from the tray. Position sensors and means are provided to ensure positional accuracy of the first ladle carried cores and the poles of the second cores. Also the coil are physically and thermally protected from ladle heat by appropriate shock absorbing and thermal insulating provisions. Thermal protection of the cores further enhanced by cooling embodiments. The ladle by itself or the ladle and tray may be enclosed in a vacuum chamber.
