| description | A method for vibration damping and shape control of a suspended metal strip (3) during continuous transport in a processing facility in a steel rolling line or surface treating line in a steel mill, where the method comprises the steps; measuring distance to the strip by a plurality of non contact sensors (2), and generating a strip profile from distance measurements decomposing the strip profile to a combination of mode shapes, and determining coefficients for the contribution from each mode shape to the total strip profile, and controlling the strip profile by a plurality of non contact actuators (1) based on a combination of mode shapes.
Cette invention concerne un procédé permettant d'amortir les vibrations et de commander la forme d'une bande métallique (3) suspendue pendant un transport en continu dans un équipement de traitement dans une chaîne de laminage d'acier ou dans une chaîne de traitement de surface dans une aciérie. Le procédé susmentionné comprend les étapes qui consistent à mesurer la distance jusqu'à la bande au moyen de plusieurs capteurs sans contact (2), puis à générer un profil de bande à partir des mesures de distances en décomposant le profil de bande en une combinaison de formes de mode, puis à déterminer les coefficients pour la participation de chaque forme de mode à l'ensemble du profil de bande, et à commander le profil de bande au moyen de plusieurs actionneurs sans contact (1) sur la base d'une combinaison de formes de mode. |
