Abstract

A method of operating a roll stand arrangement composed of one or more roughing stands and a compact rolling group arranged downstream of the roughing stands and transversely offset relative to the roughing stands. The compact rolling group is connected to the roughing stands through roller conveyors and a transverse conveying unit. The compact rolling group is composed of a first and a second universal stand or two-high stand and an intermediate upsetting stand between the first and second stands. Preliminary sections arriving from a continuous casting plant are supplied directly or after intermediate storage to the roll stand arrangement. The rolling stock strand which has been rolled in the roughing stands is supplied optionally from a first entry side or a second entry side into the compact rolling group in dependence on the number of passes required by the respective rolling program.
