Patent ID: 8459075

Claim:
A regulation method for a cold-rolling mill train which has a plurality of rolling stands, through which a cold strip passes in succession, and a strip feeding device arranged upstream of the rolling stand passed through first, the method comprising: supplying an initial setpoint speed to the strip feeding device so that the strip feeding device feeds the cold strip to the rolling stand passed through first at an initial actual speed which corresponds to the initial setpoint speed, supplying a first setpoint speed to the rolling stand passed through first so that rolls of the rolling stand passed through first rotate at a first actual speed which corresponds to the first setpoint speed, using a first thickness detection device arranged between the rolling stand passed through first and the rolling stand passed through next to detect a first actual thickness of the cold strip, determining a basic output signal on the basis of the first actual thickness of the cold strip and a first setpoint thickness of the cold strip, adjusting the first setpoint speed, but not the initial setpoint speed, on the basis of the basic output signal, so that the first actual thickness of the cold strip is matched to the first setpoint thickness of the cold strip, using a initial thickness detection device arranged between the strip feeding device and the rolling stand passed through first to detect an initial actual thickness of the cold strip, and using an initial feed-forward regulator to adjust the initial setpoint speed in such a way that the product of initial setpoint speed and initial actual thickness is set to a setpoint mass flow.
