Abstract
A method for vibration damping and shape control of a suspended metal strip 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; and generating a strip profile from distance measurements; decomposing the strip profile to a combination of mode shapes; 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 based on a combination of mode shapes.
