Abstract
In a rolling mill train (2; 30; 56) for processing rolling stock (4, 32), at least three rolling stands (10) are directly adjacent in the rolling direction and are driven by electric motors (20) having superconducting windings. It is thereby possible to keep the distances between the rolling stands smaller than with conventional electric drives, thus reducing energy losses during the rolling process. A combined casting and rolling station (40), which is equipped with such an electric motor (20) in the rolling stands, is configured and/or operated efficiently in terms of the required heating power.
