ABSTRACT:
A method and a rolling stand arrangement for rolling in a reversing operation a finished section from a preliminary section produced in a continuous casting plant, wherein the preliminary section has a web-like portion corresponding to a web of the finished section and flange-like increased thickness portions corresponding to flanges of the finished section. The rolling stand arrangement includes a rolling unit in a first rolling line with a free runout and a vertical stand for acting on the flange-like increased thickness portions of the preliminary section in order to upset the web-like portion of the preliminary section. A compact rolling stand group arranged in a second rolling line includes a first universal stand on an entry side, a second universal stand on an exit side, and an edging stand arranged between the first and second universal stands. The first rolling line and the second rolling line extend parallel to one another. A transverse conveying unit is arranged following the rolling unit and immediately in front of the entry side of the compact rolling stand group for conveying the preliminary section from the first rolling line to the second rolling line.
