Abstract (en)
[origin: WO2004009261A1] The invention relates to a method and device for correcting the thickness of a metallic strip (1) during rolling with a roll stand (2) equipped with setting elements for regulating the thickness of the metallic strip and with at least one coiler (4). The aim of the invention is to provide a method and device for correcting the thickness of a metallic strip during rolling with a roll stand, which ensures the production of rolled strips with a reduced thickness tolerance. To this end, the invention provides that an average strip thickness of a strip section is determined from at least one strip length measurement and from the measurement of the associated rotation of the coiler, and the setting elements of the roll stand are controlled at least according to the average strip thickness of the strip section. The inventive method enables the setting elements to be controlled virtually independent of the surrounding conditions of the roll stand thereby enabling the thickness tolerances of the rolled strip to be effectively reduced.
