Zusammenfassung:A rolling mill of four-high or more is provided that includes: measurement apparatuses that adopt any one roll as a reference roll, and measure at least rolling direction forces acting on roll chocks on a work side and roll chocks on a drive side of each roll other than a backup roll; pressing apparatuses that are provided on either one of an entrance side and an exit side in a rolling direction of the roll chocks, and that press the roll chocks in the rolling direction; driving apparatuses that are provided so as to face the pressing apparatus in the roll chocks, and that move the roll chocks in the rolling direction; and a position control unit that fixes a rolling direction position of the roll chocks of the reference roll as a reference position, and drives the driving apparatuses to control the positions in the rolling direction of the roll chocks based on a rolling direction force difference that is a difference between a rolling direction force on the work side and a rolling direction force on the drive side so that the rolling direction force difference of each roll is a value within an allowable range.
