Abstract: A method for reducing the strip tension of a rolling stock, may include: transporting the rolling stock using a roller table between two successive rolling units, wherein a rolling stock loop is formed in a depression in a section of the roller table between the two rolling units, the rolling stock loop being supported by the roller table at least in one off-center portion of the section, wherein the supporting line of the roller table in this portion corresponds to the catenary curve of the free span; measuring a loop depth of the rolling stock loop; calculating a desired value of the loop depth that corresponds substantially to the free span, e.g., depending on the material, thickness and temperature of the rolling stock; controlling the main drives and/or the gap adjustment of the rolling units based on the desired value and the measured loop depth, such that the loop depth substantially corresponds to the desired value.

Abstract: Based on an actual temperature upstream of a roll stand, a predicted temperature is estimated for when strip sections of the strip will roll through the roll stand. The predicted temperature is used to predict material moduli, which is used to control a regulating device that influences a roll gap for the roll stand and to parameterize a roll gap control system. A roll gap profile is predicted based on the predicted temperatures, and is compared with a nominal roll gap profile. A regulating variable that influences a profile of a roll gap is set. The regulating variable is then corrected based on the comparison with the nominal roll gap profile. The predictions are made using a prediction horizon corresponding to a plurality of consecutive sections of the strip. Control is performed for both an operator side and a drive side of the strip.

Abstract: A current temperature is ascertained for sections of a strip ahead of a first mill stand. The temperatures of the strip sections are predicted with a prediction horizon corresponding to multiple strip sections, including when each strip section is milled in the first mill stand for which time a nip profile formed by the working rolls is predicted. A control parameter for milling a specific strip section in the first mill stand is ascertained for controlling a control device of the first mill stand. A manipulated variable curve for the control device, influencing the nip profile of a nip formed by working rolls of the first mill stand, is set for the prediction horizon and optimized for the predicted nip profile and a desired profile. The current value of the optimized manipulated variable curve corresponds to the control parameter which is fed to the control device as the manipulated variable.

Abstract: In a rolling mill, an open-loop and/or closed-loop control device and a method for adjusting a discharge thickness of rolling stock which passes through a multi-stand mill train, wherein a first section of the rolling stock is rolled to a first discharge thickness, a second section of the rolling stock is rolled to a second discharge thickness which is different from the first discharge thickness. Because a transition from the first discharge thickness to the second discharge thickness takes place at a feed rate of the rolling stock into the mill train which is adjusted as a function of a discharge rate of the rolling stock of a unit which is arranged upstream of the mill train in the direction of mass flow, a method can be made available which runs essentially without reactions for units which are arranged upstream of the mill train in the direction of mass flow.
