<p><P>PROBLEM TO BE SOLVED: To provide a method of controlling tension by which the variation of rolling load is reduced, shape deterioration is prevented, also the variation of plate thickness is reduced and off-gage that is out-of-tolerance length is shortened as much as possible. <P>SOLUTION: This method of controlling the tension is a method of performing tension control of a rolled stock W by using a tension curve which shows the relationship between rolling speed and interstand tension when rolling the rolled stock W by using a rolling apparatus 1 provided with a plurality of rolling stands 2. The tension curve is determined by performing optimizing calculation by using a static rolling model which does not include any time as a variable and a static evaluation function which the evaluation function which is not integrated by time is and the interstand tension is the tension curve is determined and the interstand tension is controlled on the basis of the tension curve determined by the optimizing calculation. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
