- the use of such additional units and their integration in the rolling mill is expensive on the one hand and resource-intensive on the other hand.
- the spacing of the rolling stands can be reduced by the use of drive motors with superconducting windings, whereby additional aggregates, e.g. for descaling or for heating the rolling stock, can be omitted.
