ABSTRACT:
An electromagnetic inductor for producing a rotating magnetic field for use with an ingot mold for continuous casting of metal and provided with an apparatus for sensing the upper level of liquid metal in the mold. The inductor, of the static polyphase type, comprises an annular magnetic yoke provided with a plurality of radially inwardly projecting poles having each an exciter winding and at least two adjacent poles are spaced further in the circumferential direction of the yoke from each other than the other pole. The yoke may be provided in the region between these two poles with a cutout and beneath the cutout with a portion of increased thickness. The inductor may be used around an ingot mold for the continuous casting of metal provided with a gamma ray emitter and a gamma ray receiver located at opposite sides of the mold for detecting the position of the level of the cast liquid metal. The upper level of the inductor is located in the path of the rays from the emitter to the receiver with the pair of poles and the cutout in the yoke located along a central axis of the bundle of rays.
