<p>PROBLEM TO BE SOLVED: To achieve accurate and stable setting-up of a rolling mill by expressing the setup model in the form of weight sum of explanatory variables and correcting the weighting factor by sequential method of least squares. SOLUTION: A measured value collecting means 3 collects measured values of, for example, flow stress and reduction stress and the like when a rolled material 2 is cold-rolled or hot-rolled by a rolling mill 1. A sequential least square calculation means 4 calculates the weighting factor of the setup model on the basis of the measure value collected by the measured value collecting means 3. A setup calculation means 5 determines the setup values of the rolling mill 1 on the basis of the weighting factor calculated by the sequential least square calculation means 4. Also, the setup calculation means 5 determines the setup values of the rolling mill 1 of reduction amount, rolling load, and reduction position each pass time when the rolled material 2 is passed through the rolling mill 1 on the basis of respective mathematical models.</p> |
