Abstract

Bei einem Stabstahlwalzwerk mit Wasserkühlstrecke (9) vor der Fertigstaffel (4, 5) zum thermo-mechanischen Fertigwalzen wird jeweils eine Gerüstgruppe (12-14 bzw. 15-17) der Zwischenstaffel (2) oder der Zwischenstaffeln (2, 3), die auf das Walzen eines größeren Fertigquerschnittes als dem kleinstmöglichen Fertigquerschnitt eingestellt ist, auf eine Gerüststelle (22 bzw. 25) der Fertigstaffel (4) umgesetzt, der eine Wasserkühlstrecke (9) unmittelbar vorgeordnet ist. Die Fertigstaffel (4) für den kleinstmöglichen Fertigquerschnitt braucht nicht mehr auf größere Fertigquerschnitte umgebaut zu werden, sondern wird einfach durch eine Gerüstgruppe aus einer oder mehreren Zwischenstaffeln (2, 3) ersetzt. Zum Umsetzen von Gerüstgruppen kann Kranarbeit wegfallen, wenn Schnellwechselvorrichtungen (26, 30, 34) verwendet werden, die alle durch ein sich parallel zur Walzlinie erstreckendes Schienenpaar (38), das sich bis zu der oder den Gerüststellen (22, 25) der Fertigstaffel (4) erstreckt, miteinander verbunden sind. Ein thermo-mechanisches Fertigwalzen der größeren Fertigquerschnitte ist erreichbar, ohne die Fertigstaffel auf alle gewünschten Fertigquerschnitte umbauen zu müssen. In a steel bar mill with a water cooling section (9) in front of the finishing line (4, 5) for thermo-mechanical finishing rolling, a stand group (12-14 or 15-17) of the intermediate line (2) or the intermediate lines (2, 3), the is set to the rolling of a larger finished cross-section than the smallest possible finished cross-section, implemented on a scaffolding point (22 or 25) of the finished relay (4), which is directly upstream of a water cooling section (9). The finishing line (4) for the smallest possible finished cross-section no longer needs to be converted to larger finished cross-sections, but is simply replaced by a scaffolding group made up of one or more intermediate levels (2, 3). Crane work can be omitted to transfer scaffolding groups if quick-change devices (26, 30, 34) are used, all of which are provided by a pair of rails (38) extending parallel to the rolling line, which extends up to the scaffolding point (s) (22, 25) of the finishing 4) extends, are interconnected. Thermo-mechanical finish rolling of the larger finished cross sections can be achieved without having to convert the finishing line to all the desired finished cross sections.
