<p>PROBLEM TO BE SOLVED: To maintain conformity to especially narrow dimensional tolerance in manufacturing of a profiled rolling material at a relatively low manufacturing cost, in an operation method for a rolling path. SOLUTION: By comparing a measured profile (54) of the rolling material in process with a target profile, then based on a deviation of a measured profile from the target profile, modified target values (Ki ) in relation with weight factors (Wi ) inherent to each stand are replaced with the target values (SW) for entire rolling stands or each stand (4, 6, 8).</p> |
