Claim 10:
11. The method for setting a rolling mill according to claim 10, wherein:
the rolling mill includes a plurality of rolls, including one roll of the pair of work rolls as an upper work roll and one roll of the pair of backup rolls as an upper backup roll, provided on an upper side in the vertical direction with respect to the workpiece, and a plurality of rolls, including another roll of the pair of work rolls as a lower work roll and another roll of the pair of backup rolls as a lower backup roll, provided on a lower side in the vertical direction with respect to the workpiece,
from a roll assembly having an order of the lower backup roll, the lower work roll, the upper work roll, and the upper backup roll, starting on an opposite side to the reference roll, the roll chocks of the rolls are moved in the rolling direction of the workpiece to adjust the positions of the roll chocks so that the rolling direction force differences arising at each of the rolls that are adjacent fall within an allowable range, and
at such time, the roll chocks of the rolls for which the position of the roll chocks is already adjusted are controlled simultaneously and in a same direction while maintaining relative positions with respect to the roll chocks of the roll that is being adjusted.
