ABSTRACT:
A method of controlling the passage of rolling stock through a continuous mill train of successive roll stands comprising rolling shafts supporting the rolls, a rolling-mill drive preceding the rolling shafts, and individual electric motor drives having a steplessly variable rotary speed connected to the rolling-mill drive to apply torque to the rolling shafts, which comprises the steps of (a) measuring a reaction force on a machine part of a respective one of the stands to obtain a physical parameter changing in dependence on the torque before and after an initial pass of a stand succeeding the one stand, and (b) controlling the rotational speed of the individual electric motor drive for the succeeding one stand in dependence on any change of the measured physical parameter.
