Abstract
Angles of an upper-side pair of an upper work rollA and an upper backup rollA, and a lower-side pair of a lower work rollB and a lower backup rollB are adjusted in a state where the upper-side pair is kept parallel and in a state where the lower-side pair is kept parallel. Thereafter, work-roll pressing apparatusesA andB, work-roll position control apparatusesA andB, backup-roll pressing apparatusesA andB, and backup-roll position control apparatusesA andB are controlled such that the angles of the upper work rollA and the lower work rollB are adjusted in a state where the angles of the upper backup rollA and the lower backup rollB are maintained.
