Abstract

PURPOSE: To eliminate a difference between the front and back sides of a strip, and to prevent generation of an L-shaped camber, etc., by reciprocally passing a strip between a central large diameter, driving work roll and small diameter cluster rolls arranged above and below the central roll, and by applying a strecth-and- bending rolling work to the strip.
CONSTITUTION: A constant tension is applied to a strip S between a large diameter, driving work roll 13 and the lower multistage cluster rolls A, and a large bending is given to the strip S on the side of a small diameter work roll 7; under this condition, a stretch-and-bending rolling work is applied to the strip S. When a coil held in a coiler 1 finishes a rolling work, the rotation of all of the coiler 1, an uncoiler 25, and each roller, are reversed, and an upper mutistage cluster roll B is moved down; then, the strip S is passed between a small diameter work roll 14 and the central work roll 13 in order to bend the strip S toward the roll 13 side; under this condition, a stretch-and-bending rolling work is applied to the strip S. According to the present method, a single rolling stand can eliminate the difference between the front and back sides, and the generation of an L-shaped camber, etc., can be prevented.
