<p>PURPOSE:To calculate, decide, and perform the automatic operation of predictive shape suitable for the item of operating condition of a rolling mill by controlling the shape of a board by varying the evaluating point position of shape steepness corresponding to board thickness. CONSTITUTION:When the shape control of the board is performed by the shape steepness and the shape steepness of each stand output side is predictively calculated, the matching of the predictive shape with the visual shape of an operator can be obtained by performing the shape control of the board by setting the evaluating point position of the shape steepness at distance (x) from a board terminal and varying it corresponding to the board thickness so as to be fitted in the item of rolling conditions for board thickness, board width, material temperature, and deformation resistance, etc. Also, when the shape control of the board is performed by the shape steepness calculated from an output side crown, it is calculated setting the evaluating point of the output side crown at distance (x) from the board terminal, and the value of distance (x) is varied corresponding to the board thickness, and the matching calculated shape with the visual shape by the operator can be obtained, and the board is passed through without performing manual interposition for the setting value of a shape control means (vender).</p> |
