ABSTRACT:
An electromagnetic centrifuging inductor structure for creating a rotating magnetic field for rotating molten metal about its casting axis while passing through the casting conduit of a continuous casting type ingot mold includes an annular core body of magnetic material surrounding the casting conduit and which is provided with six poles or teeth on which are respectively mounted six different arcuate coils for energization by a three-phase a.c. source. Two coils are provided for each phase and these are so distributed that two coils of the same phase have different radii, are mounted on two diametrically opposite teeth and are coupled in such manner that their generated magnetic fluxes are additive. The coils are mounted in recesses formed between adjacent teeth and the coils of different phases partially overlap within the same recess.
