Abstract

A roll rearrangement device 100 includes a carriage 110 that can travel in the axial directions of a second intermediate roll 4 and a backup roll 5 provided in a multi-high rolling mill 200, a support beam 130 that is provided so as to be movable with the travelling of the carriage 110 and taken in and out of the multi-high rolling mill 200, and two roll holding sections that are provided with an interval in the axial direction of the support beam 130 and can attach and detach the second intermediate roll 4 and the backup roll 5. This makes it possible to provide a roll rearrangement device and a roll rearrangement method that can improve the safety of rearrangement work as compared with conventional ones by realizing parallel insertion and extraction of rolls during roll rearrangement.
