Abstract (en)

[origin: EP4019156A1] A rolling mill includes: bending cylinders 740, 741, and 744 for applying a bending force vertically to bearing housings 712 and 713 to thereby cause work rolls 710 and 711 to perform bending; a backlash elimination cylinder 760 for applying a pressing force in a rolling direction to the bearing housings 712 and 713; and members 712A and 713A disposed between the bending cylinder 741 and the bearing housings 712 and 713, and receiving the bending force from the bending cylinder 744. The bending cylinders 740 and 741 and the backlash elimination cylinder 760 are disposed axially on one of the entry and exit sides in the rolling direction, and the bending cylinder 741 and the members 712A and 713A are disposed on the other of the entry and exit sides in the rolling direction.
