Abstract (en)
[origin: FR2879486A1] The regulation of the flatness of a metal strip at the outlet of a rolling cage uses a flatness regulation device incorporating at least one dynamic flatness driver which, during rolling, characterises the flatness of the strip by measuring a height (D) at n points distributed over the length of the strip. From the n measurements of this height, using a model of the flatness regulation action and an optimisation method, a global consigned value is determined for the regulation system. The global consigned value comprises at least one elementary value for a dynamic driver, such that a criterion of residual default of the calculated flatness may be minimal and global consigned value is executed by the regulation system. The action model on the flatness utilised to determine the global consigned value is made up for each dynamic driver, providing sub-models for each of the n points of measurement of the height characteristic of the flatness. Each sub-model allows the calculation of the effect on the height at the corresponding point of the dynamic driver when the consigned value is applied. An independent claim is included for a computer program for operating this method of flatness regulation.
