Claim 8:
9. A method for setting a rolling mill,
the rolling mill being a rolling mill of four-high or more that includes a plurality of rolls including at least a pair of work rolls and a pair of backup rolls supporting the work rolls,
the method for setting a rolling mill being executed before reduction position zero point adjustment or before starting rolling,
wherein any one roll among respective rolls arranged in a vertical direction is adopted as a reference roll,
the method comprising:
measuring at least rolling direction forces in a rolling direction that act on roll chocks on a work side and roll chocks on a drive side of the rolls other than the backup rolls, and
fixing a rolling direction position of roll chocks of the reference roll as a reference position, and moving roll chocks of the rolls other than the reference roll in a rolling direction of a workpiece to adjust positions of the roll chocks so that a rolling direction force difference that is a difference between a rolling direction force measured on the work side and a rolling direction force measured on the drive side falls within an allowable range.
