Abstract
The work rolls of two sets of roller groups are held within one-piece metal chock in a rolling mill. A one-piece metal chock in which the driving side and operating side are separate then provides support at the upper part of the rolling material, with support similarly being provided at the lower part using another pair of single piece metal chocks. Two sets of roll groups can then be arranged close to each other, strip walking and strip curving can be prevented, and a rolling mill, rolling method and rolling installation that are easy to maintain and provide superior rolling efficiency can be provided.
