The present disclosure relates to an electromagnetic brake system (1) for a metal-making process. The electromagnetic brake system (1) comprises: a first magnetic core arrangement having a first long side and a second long side, which first long side has Nc teeth and which second long side has Nc teeth, wherein the first long side and the second long side are arranged to be mounted to opposite longitudinal sides of an upper portion of a mould, a first set of coils, wherein the first set of coils comprises 2Nc coils (9-1,…,9-16), each coil being wound around a respective tooth of the first magnetic core arrangement, and Np power converters (11-1,…,11-4), with Np being an integer that is at least two and Nc is an integer that is at least four and evenly divisible with Np, wherein each power converter (11-1,…,11-4) is connected to a respective group of 2Nc/Np series-connected coils (9-1,…,9-16) of the first set of coils, and wherein each of the Np power converters (11-1,…,11-4) is configured to feed a DC current to its respective group of 2Nc/Np series-connected coils (11-1,…,11-4).This disclosure further relates to a method of controlling molten metal flow in a metal-making process. |
