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.
A method of rolling finished sections from a preliminary section in a reversing rolling stand arrangement, the rolling stand arrangement including a compact rolling stand group with a first universal stand on an entry side, a second universal stand on an exit side and a first edging stand arranged between the first and second universal stands, a second edging stand being arranged in front of the entry side of the compact rolling stand group, the preliminary section being a section arriving from a continuous casting plant and having increased thickness portions at both ends of a web corresponding to the finished section, the method including, depending on at least one predetermined dimension including web height, web thickness and flange width, of the finished section to be rolled, introducing the preliminary section one of directly into the first universal stand of the compact rolling stand group and subsequently finish-rolling the section in the compact rolling stand group into the finished section having the predetermined dimensions, and, prior to introducing the preliminary section into the first universal stand of the compact rolling stand group, subjecting the preliminary section to a reducing rolling in a rolling unit arranged immediately in front of the compact rolling stand group in order to achieve different dimensions deviating from an original determination of the at least one dimension including web height, web thickness and flange width of the finished section to be finish-rolled in the compact rolling stand group, the improvement comprising carrying out the reducing rolling of the preliminary section in a rolling line with free runout extending parallel to a rolling line of the compact rolling stand group, transversely displacing the preliminary section from the rolling line with free runout into a position immediately in front of the compact rolling stand group, and subsequently introducing the preliminary section into the compact rolling stand group.
