Abstract (en)
An electromagnetic stirring and heating device (6) for an ingot casting device for ingot casting is presented. The ingot casting device comprises a mould (1-3) for casting of an ingot. The electromagnetic stirring and heating device (6) is arranged at a top of the mould. The electromagnetic stirring and heating device is configured to macroscopic stir the ingot with a varying frequency in the range 0-10 Hz, and to heat at a top of the ingot with a superimposed varying frequency in the range 20-200 Hz, on top of the electromagnetic stirring varying frequency. A method and an ingot casting device therefore are also presented.
