Abstract
PURPOSE: To set the aimed rolling speed at nearly a rated rotational, speed, and to improve the rolling efficiency, by controlling the rolling speed as follows; when a speed-up request is given to a prescribed stand while it is operating at its highest speed or so, if the present rolling speed of this stand is higher than its highest speed, all other stands are uniformly slowed down.
CONSTITUTION: Rolling stands F1WF7 are independently driven and the motor group is under the control of a speed controller 4 to be given a control input sent from a stand-speed fine adjuster 7 after correcting a speed signal generated by a master rheostat 5 and a single stand rheostat 6. Hereupon, if a speed-up request is given to stands F5WF7, since the stand F5 is rotating at its rated rotational speed, a master rheostat decline controller 9 operates a decline of the master rheostat, and a driver 10 declines the master rheostat 5 at a prescribed rate, and other stands are uniformly slowed down. As a result, the stand F5 is relatively speeded up.
