Abstract

PURPOSE:To drastically improve the accuracy in the shape control of a rolled stock by performing the correction of the set value of the respective shape operation end corresponding to the variation of a rolling state. CONSTITUTION:The set value of the shape operation end controlling the symmetric component in each shape operation end is corrected based on the set correction amount operated by a symmetric component amount arithmetic means 13. Also, the shape pattern in the plate width direction orthogonal with the moving direction of a rolled stock 1 at the rolling mill outlet port side is made to be controlled in the target shape pattern in the plate width direction orthogonal with the moving direction of the rolled stock at the rolling mill outlet port side by correcting the set value of the shape operation end controlling the asymmetrical component in each shape operation end, based on the operated set correction amount by an asymmetrical component correction arithmetic means 14, so the optimum solution of the set value correction amount at the respective shape operation end can easily be found in the rolling mill having a lot of shape operation ends, the correction of the set value of each shape operation end can be performed corresponding to the variation of the rolling state and the accuracy in the shape control of the rolled stock can be improved drastically.
