Abstract (en)

[origin: EP0846503A2] The method involves use of roll stand configurations of which one is a compact rolling group consisting of entry and exit universal stands and an interposed upsetting stand. This group is preceded by a preliminary rolling group consisting of vertical and horizontal stands and/or universal stands. To produce pile planking, angle and similar sections - with one or more stands of the preliminary rolling group and/or one or more stands of the compact rolling group provided with several grooved rolls or rolls with adjacent grooves which can be brought into and out of the rolling line - forming of a rectangular section or a preliminarily formed section with near-final dimensions into a finished section takes place in the preliminary rolling groups in several form change and reduction stages, followed by further analogous stages in the universal rolling group, with or without use of the reversing mode of operation of the roll stands involved. Also claimed is a corresponding rolling installation.
