ABSTRACT:
A rolling mill is equipped with a work roll bending apparatus for controlling the strip crown of the strip. Upstream and downstream of the rolling mill are located strip crown meters which measure the thickness of the strip in the transverse direction. The variables of the work roll bending apparatus are manipulated, and determining the inheritance coefficient is determined on the basis of measurement values of the strip crown of the strip measured by the strip crown meters.
