Rolling of a strip in a rolling train using the last stand of the rolling train as a tension reducer

An operating method for a rolling train for the rolling of a strip wherein

• the rolling train comprises a number of main rolling stands and a coiler arranged downstream of the main rolling stands,
• the main rolling stands respectively having work rolls and at least backing rolls, the method comprising the steps of:
• feeding data of the strip, which establish at least an overall pass reduction other than zero by which an initial thickness of the strip is to be reduced in the rolling train, to a control device of the rolling train,
• determining by the control device individual pass reductions for the main rolling stands on the basis of the data fed to it,
• controlling by the control device the main rolling stands and the coiler in such a way that the strip is rolled in the main rolling stands in a way corresponding to the individual pass reductions determined and is then coiled up by the coiler,
• determining by the control device the individual pass reductions in such a way that the individual pass reduction of the main rolling stand arranged directly upstream of the coiler is zero, and
• controlling by the control device the main rolling stand arranged directly upstream of the coiler in such a way that, with respect to this main rolling stand, the tension on the outlet side is less than the tension on the inlet side, but the strip runs through this main rolling stand without undergoing forming, at least on one side.
