Abstract
A rolling train for rolling girder sections includes at least one two-high reversing roughing stand and a plurality of subsequent universal stands for work rolling and finish rolling. Two universal stands and an upsetting stand are combined to form a reversing tandem group. A universal sizing stand for passing rolling is arranged immediately subsequent to the tandem group. The universal stands of the tandem group have double-cone shaped vertical rolls and the universal sizing stand has cylindrical vertical rolls. The girder section is rolled in several successive passes with the flanges of the section being directed outwardly and the outwardly directed flanges are rolled so as to extend parallel in a last smoothing pass.
