PROBLEM TO BE SOLVED: To suppress the meandering of a rolling material in any of cases in which camber does not occur in the rolling material but the rolling material is off-centered as a whole, and in which the camber occurs in the rolling material. ! SOLUTION: A control device 101: sets a draft leveling amount for a first finishing stand 3a based on an off-center amount measured by an off-center amount measuring instrument 102 during the interval until the tip end of a rolling material passes through the first finishing stand 3a; adjusts the draft leveling amount for the first finishing stand 3a on the basis of a camber amount measured by a camber amount measuring instrument 103 after the tip end of the rolling material has passed through the first finishing stand 3a; and, for a rolling stand after and including a second finishing stand 3b, adjusts a draft position in such a manner that gaps between a work roll on the working side and on the drive side are equal to each other based on a rolling conditio |
