Abstract

One embodiment of the present invention discloses a method for operating a mill train, in particular used in a cold-rolling mill. The mill train includes operating rolls with a roll gap disposed in-between through which a rolled strip is guided. With the method of at least one embodiment, the thickness and the roll-in speed of the rolled strip are measured in front of the roll gap. The roll-out speed of the rolled strip after the roll gap is reconstructed with the aid of the tangential speed of the operating rolls. The thickness after the roll gap is then determined with the aid of the thickness and the roll-in speed in front of the roll gap and the reconstructed roll-out speed.
