Abstract

At least the working rolls in two groups of rolls are held by unitary metal chocks. The driving side portion and operating side portion of a material to be rolled are held at the upper side thereof by separately formed unitary metal chocks, and at the lower side thereof as well by similar unitary metal chocks. Two groups of rolls can be arranged close to each other, and the meandering and a bend of a material to be rolled are prevented. A rolling mill and a rolling method and rolling equipment which are easy to maintain and provide a high rolling efficiency can be provided.
