Japanese Patent JP6470134

B2

Provided is a rolling mill, a tandem rolling line including the same, and a rolling method capable of using small-diameter work rolls for rolling hard materials and capable of high-quality strips. A rolling mill includes work rolls (2a, 2b) configured to roll a rolling material (1), intermediate rolls (3a, 3b) supporting the work rolls (2a, 2b) from above and below, respectively, back-up rolls (4a, 4b) supporting the intermediate rolls (3a, 3b) from above and below, respectively, and position adjusting means (9a to 9h) for adjusting the positions of the intermediate rolls (3a, 3b) relative to the work rolls (2a, 2b) and the back-up rolls (4a, 4b) in the direction of conveyance of the rolling material (1). The rolling mill is characterized in that it comprises: detecting means (25a to 25h, 26a to 26h; 27a to 27h; 28a to 28h; 29a, 29b; 35a) for detecting horizontal forces on the work rolls (2a, 2b); offset-amount calculating means (42) for calculating the offset amounts of the intermediate rolls (3a, 3b) based on the horizontal forces on the work rolls (2a, 2b) detected by the detecting means (25a to 25h, 26a to 26h; 27a to 27h; 28a to 28h; 29a, 29b; 35a); and controlling means (43) for controlling the position adjusting means (9a to 9h) such that the positions of the intermediate rolls (3a, 3b) are offset by the offset amounts calculated by the offset-amount calculating means (42).
