摘要： A method for controlling flatness in cold-rolling mills having a roll stand with at least six rolls including intermediate and working rolls capable of being deflected, includes measuring tensile stress distribution over the width of a strip to be rolled having central and edge regions, comparing the measured tensile stress distribution with a desired predeterminable tensile stress distribution, determining a deviation at the central region of the strip between the measured and desired tensile stress distribution, determining a deviation at the edge region of the strip between the measured and desired tensile stress distribution, forming a strip center coefficient from the central region deviation in the form of a deviation control for influencing deflection of the intermediate roll, and forming a strip edge coefficient from the edge region deviation in the form of a deviation control for influencing deflection of the working roll, and a circuit for carrying out the method.
