摘要： 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.

摘要： Multistage rolling mill having a pair of upper and lower work rools, a pair of upper and lower backup rolls, and an intermediate roll provided between at least one of the work rolls and the associated backup roll, all of which rolls are arranged in a substantially vertical direction; intermediate rollers supporting the work rolls in the direction of a path of a work; and support rollers supporting the intermediate rollers, characterized in that each of the support rollers consists of a plurality of axially arranged divided rollers which are staggered in succession in the axial direction of the support roller so that the axis of each of the divided rollers is spaced vertically from that of the adjacent divided roller. Since the work rolls in the rolling mill are supported on the support rollers of the above-described construction, a space can be secured between each of the suppport rollers and the associated backup roll, which supports the work roll in a substantially vertical direction, or the associated intermediate roll. Accordingly, the support rollers and backup rolls or intermediate rolls do not contact each other, so that the diameter of the work rolls can be reduced. Moreover, since each intermediate roller which supports the associated work roll directly is supported reliably by two divided rollers the axes of which are spaced from each other, the work roll can be supported stably. This enables a highly accurate and stable rolling operation.
