In a tandem rolling mill a control computer integrates the entry speed of a work strip having a gauge transition to determine the arrival of the transition at a first roll stand. At that time a screw-down on that stand is updated through a scheduling computer while roll speeds on all the stands remain unchanged. When the gauge transition arrives at each of the succeeding stands as determined by the control computer integrating a roll speed on the preceding stand, the scheduling computer updates a screw-down on the arrival stand and changes roll speeds so as to minimize the sum of the squares of changes in roll speed with the constant mass flow relationship fulfilled. |
