<p><P>PROBLEM TO BE SOLVED: To provide a method of controlling plate thickness in a rolling mill, by which the plate thickness of a rolled stock is brought close to the target value surely. <P>SOLUTION: In the method of controlling the plate thickness for controlling the roll gap of the rolling mill for rolling the rolled stock, the variable valueΔP' of the rolling load which satisfies a gauge meter expression is calculated while taking the dynamic characteristic into consideration. After that, by using the calculated variable valueΔP' of the rolling load of the dynamic characteristic, the amount of correctionΔS of the roll gap is determined and the obtained amount of correctionΔS of the roll gap is applied to the rolling mill. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
