Abstract
A method and apparatus for a very exact correction of the thickness profile of strip rolled in a multi-stand hot strip mill. A measuring device determines the distribution of tensions in the cross-section of the strip (19). The measuring values are processed in a computer (32) to manipulated variables for a swinging or tilting device and a roll bending device (42). The roll bending device (42) is installed at the end of a hot strip mill train, and one or several roll swinging or tilting devices with measuring devices are provided, as seen in rolling direction, before the roll bending device (42).
