Abstract

A method of operating a roll stand arrangement including one or more edging/roughing stands followed by a compact rolling group arranged transversely offset relative to the edging/roughing stands and connected to the edging/roughing stands through connecting roller conveyors and a transverse conveying unit. The compact rolling group is composed of first and second universal stands or two-high stands and an intermediate edging stand arranged between the first and second stands. In accordance with a predetermined cycle, preliminary sections arriving from a continuous casting plant are supplied directly without intermediate storage to the roll stand arrangement and are finish rolled successively in the compact rolling group into profiled rolled strands and are supplied, before or while the next following preliminary section enters the compact rolling group, to a cooling bed arranged laterally of the rolling line. When rolling sections whose finish rolling time is longer than the cycle predetermined by the continuous casting plant, a first length portion of the rolled strand which has already emerged from the compact rolling group is severed from the rolled strand and is supplied to th…
