Abstract (en)
[origin: EP2684623A1] The method involves assigning variable speed control to roller (13) of each roll stand (4) of rolling train (2). A simulated load torque is supplied to control circuit of drive units (8) depending on actual load moment, based upon application of real load torque to control circuit of drive units for speed control of drive units.
