摘要： PROBLEM TO BE SOLVED: To prevent slip marks in a circumferential direction, which are generated on the surfaces of work rolls in a plate mill having non-driven divided back-up rolls.
SOLUTION: A plate mill has an upper and lower roll assemblies 16, 17, and at least one of the assemblies includes non-driven divided back-up rolls 22, 23, each of which is divided into three or more pieces in the axial direction. In the plate mill, drag rolls 41, 46 are brought into contact with the divided back-up rolls 22, 23 while straddling two or more divided rolls that are adjacent to each other in the axial direction, and pressed against the back-up rolls, so that the rotation of at least one of the divided back-up rolls is transmitted to other divided back-up rolls through the friction force of the surfaces of the rolls. Thus, all divided back-up rolls 22, 23 are rotated simultaneously and at the same peripheral speed as that of work rolls 19.
