Abstract: An electromagnetic brake system for a metal-making process. The electromagnetic brake system includes a two-level magnetic structure, in particular an upper magnetic core structure configured to be mounted to an upper portion of a mold and a lower magnetic core structure configured to be mounted to a lower portion of a mold. Lateral coils on the upper magnetic structure are configured to be controlled to generate a first magnetic field in a first field direction and inner coils are configured to be controlled to generate a second magnetic field in a second field direction, simultaneously with the first magnetic field. The lower magnetic core structure has lower coils which are configured to be controlled to generate a third magnetic field in the first direction simultaneously as the lateral coils and the inner coils generate their fields.
