<P>PROBLEM TO BE SOLVED: To provide a method of rolling a metal strip capable of uniformly improving a thickness distribution (plate thickness distribution) in a plate width direction of a rolled material in a rolling cycle, in rolling using a rolling mill with a shift mechanism axially shifting work rolls. <P>SOLUTION: In the method of rolling a metal strip, when rolling the rolled material using the rolling mill with the shift mechanism axially shifting the work rolls in a rolling line of the metal strip, a shift position change amount for each one rolled material is fixed in the rolling cycle, and the shift position change amount and a turning back position reversing the shift moving direction of the work rolls are determined such that, with respect to all the rolled materials to be rolled in the rolling cycle, an error between an estimated calculated value of a work roll profile on a contact part between the rolled material and the work roll and a work roll profile target value is obtained, and the total value of the errors with respect to all the rolled materials in the rolling cycle is minimized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
