ABSTRACT:
A method for improving the contour of rolled material over at least one segment of a rolling schedule including a plurality of rolling processes. The method includes associating at least one quality criterion with at least one rolling stand of at least one of the plurality of rolling processes, optimizing the at least one quality criterion using a mathematical formula, predetermining at least one work roll shift for the plurality of rolling processes over the at least one segment of the rolling schedule based on an optimization of the at least one quality criterion, and axially shifting at least one work roll of the at least one rolling stand.
