ABSTRACT:
In a bar steel rolling mill with a water-cooling segment upstream of a finishing train for thermomechanical finish rolling, respectively, one group of stands of an intermediate train or of intermediate trains, which is adjusted for rolling a larger finish cross-section than the smallest possible finish cross-section, is transferred to a stand location of the finish train, which has a water-cooling segment directly upstream of it. The finishing train for the smallest possible finished cross-section no longer needs to be refurbished to the larger finish cross-section, rather it is simply replaced by a group of stands from one or several intermediate trains, and rapid change devices are utilized for moving the strands and are all connected with each other by a pair of rails extending parallel to the rolling line up to at least one stand location of the finish train. A thermomechanical finish rolling of a larger finish cross-section being achieved without having to refurbish the finishing train to all desired finish cross-sections.
