Description
Die Erfindung bezieht sich auf ein Verfahren zum Gießen und Walzen und eine Walzgerüstanordnung zum Walzen von Fertigprofilen (Spundwandprofilen) aus einem endabmessungsnahen, aus einer Stranggußeinrichtung kommenden Vorprofil mittels, in einer Walzlinie im Reversierbetrieb arbeitender Walzgerüstanordnungen, von denen die eine, eine Kompaktwalzgruppe, bestehend aus einem eingangsseitigen ersten Universalgerüst, einem ausgangsseitigen zweiten Universalgerüst und einem, zwischen diesen Universalgerüsten angeordneten Stauch-Zwischengerüst darstellt, der eine, aus Vertikal- und Horizontal-Walzgerüsten bestehende Vorwalzgruppe vorgeordnet ist, wobei für das Walzen der Spundwandprofile, bei Ausstattung eines Walzgerüstes der Vorvalzgruppe und eines der Walzgerüste der Kompaktwalzgruppe mit wahlweise in die und aus der Walzlinie herausbringbaren Wahlkalibern, die Formung des Vorprofils in den Walzgerüsten der Vorwalzgruppe in einer Reihe von Formänderungs- und Formreduzierwalzstichen mit oder ohne Einsatz der Wahlkaliber bewirkt und anschließend in der Kompaktwalzgruppe, in mehrere Formänderungs- bzw. Formreduzierstichen und Reversierstichen im eingangsseitigen Universalgerüst und im Stauchzwischengerüst mit oder ohne Einsatz der Wahlkaliber bewirkt wird, und die Kompaktwalzgruppe als Tandem-Gerüstgruppe arbeitet.The invention relates to a method for casting and rolling and a roll stand arrangement for rolling finished profiles (sheet piling profiles) from a near-final dimension, from a continuous casting device coming pre-profile by means of, in a rolling line in reversing operation working mill stand arrangements, of which one, a compact rolling group consisting of a first input Universal scaffold, a second universal scaffold on the output side and a compression intermediate scaffold arranged between these universal scaffolds represents the one, from vertical and horizontal rolling stands existing roughing group is arranged, whereby for the rolling of sheet piling profiles when a rolling stand is equipped the Vorvalz group and one of the stands of the compact rolling group with optional calibres that can be brought into and out of the rolling line, the formation of the preliminary profile in the rolling stands of the preliminary rolling group in a series of shape change and shape reduction passes with or without the use of the optional caliber and then in the compact rolling group, in several shape change or shape reduction passes and reversing stitches in the universal scaffold at the entrance and in the upsetting intermediate frame with or without the use of the optional calibers is effected, and the compact rolling group as a tandem stand group is working.
Das Walzen von Spundwandprofilen wurde bisher durchweg in reversierend arbeitenden Walzstraßen mit allein stehenden Gerüsten und freiem Auslauf des Walzgerüstes durchgeführt, weil die Vielzahl der für die Vorwalzung solcher Profile notwendigen Formkaliber große Reversiervalzgerüste mit, die Vielzahl der Formkaliber aufnehmenden großen Ballenlängen der Walzen erforderte. Diese großen Gerüste und die Walzen selbst sowie die notwendigen Manipuliereinrichtungen für das Einbringen des Walzgutes in die verschiedenen Kaliber sind sehr aufwendig, haben einen großen Platzbedarf und erbringen verhältnismäßig geringe Durchgangsleistungen. Die großen Mengen des Walzgutes selbst führen dabei zu verhältnismäßig langen Walzzeiten beim reversierenden Walzen und lassen es praktisch nicht zu, derartige Anlagen in Arbeitstaktfolge mit einer Stranggießanlage zu betreiben. Es sind deshalb bei einem Verbundbetrieb zwischen Stranggießanlage und Walzanlage verhältnismäßig große Zwischenlager notwendig.Rolling sheet pile sections has so far been reversing working rolling mills with stand-alone stands and Free run of the roll stand carried out because of the variety of large calibers necessary for the pre-rolling of such profiles Reversing valance frames with the large number of shape calibers large bale lengths of the rollers required. These big scaffolds and the rollers themselves and the necessary manipulation devices for the introduction of the rolling stock into the different calibers is very complex, require a large amount of space and are proportionate low throughput. The large quantities of the rolling stock even lead to relatively long rolling times reversing rollers and practically do not allow such To operate systems in working cycle sequence with a continuous caster. It is therefore in a combined operation between the continuous caster and rolling mill relatively large intermediate storage necessary.
Man hat deshalb für das Walzen von Spundwandprofilen bereits in einer nicht vorveröffentlichten älteren Patentanmeldung vorgeschlagen, in einer Kompaktwalzgruppe, die aus einem eingangsseitigen und einem ausgangsseitigen Tandemgerüst mit jeweils zwei oder mehr Kaliber aufweisenden Duo-Walzenpaaren und diesen zugeordneten Querschiebeeinrichtungen für das Walzgut und einem, zwischen beiden Tandemgerüsten angeordneten Stauchzwischengerüst mit oder ohne Wahlkaliber besteht, das vorgeformte Vorprofil in dem ggfs. mit profilierten Horizontalwalzen ausgestatteten Universalgerüst und in dem ggfs. ebenfalls profilierte Horizontalwalzen aufweisenden Horizontal-Duo-Gerüst der Vorwalzgruppe in mehreren reversierenden Stichen zwischen beiden Walzgerüsten profilverändernd zu formen und anschließend, reversierend in den Kalibern der beiden Tandemgerüste mit oder ohne Einschluß eines Stiches in dem, profilierte Walzen aufweisenden Stauchzwischengerüst fertig zu formen.One has therefore already in for the rolling of sheet piling profiles proposed an unpublished older patent application, in a compact rolling group consisting of an input and an output-side tandem frame with two or more each Duo roller pairs with caliber and assigned to them Cross slide devices for the rolling stock and one, between the two Tandem stands arranged with or without compression intermediate stands There is an optional caliber, the preformed pre-profile in the with if necessary profiled horizontal rollers equipped universal stand and in the possibly also having profiled horizontal rollers Horizontal duo stand of the roughing group in several reversing To form stitches between the two roll stands and to change the profile then, reversing in the calibres of the two tandem frames with or without the inclusion of a stitch in the profiled rollers having the forming intermediate intermediate scaffold ready.
Mit diesen oder ähnlichen Verfahren und Gerüstanordnungen ließen sich jedoch nur geringe Leistungen erzielen, und die Führung des bereits formgewalzten Profils in den Tandemgerüsten bereitete technische Schwierigkeiten. Herstellen ließen sich dabei im wesentlichen nur Spundwandprofile mit U-Profil, nicht aber solche mit dem inzwischen in den verschiedenen Märkten sehr gefragten Z-Profil.Using these or similar processes and scaffolding arrangements perform poorly, however, and lead the already form-rolled profile in the tandem stands technical difficulties. Essentially, it could be manufactured only sheet piling profiles with U-profile, but not those with the Z profile, now very popular in the various markets.
Der Erfindung liegt die Aufgabe zugrunde, das bekannte Verfahren zum Gießen und Walzen und die Walzgerüstanordnung zum Walzen von Spundwandprofilen so zu verbessern, daß die oben erwähnten Nachteile und Schwierigkeiten beseitigt werden und das Walzen von Spundwandprofilen sowohl mit U-Querschnitt, als auch das von solchen mit Z-Querschnitt in allen Größenordnungen und mit einer guten Leistung der Walzgerüstanordnung ermöglicht wird.The object of the invention is the known method for casting and rolling and the roll stand arrangement for rolling To improve sheet piling profiles so that the disadvantages mentioned above and difficulties are eliminated and the rolling of sheet piling profiles both with a U cross section and that of a Z cross section in all sizes and with good performance the roll stand arrangement is made possible.
Diese Aufgabe wird dadurch gelöst, daß die Vorwalzgruppe in einer Walzlinie einen Auslaufrollgang aufweist und diesem eine Quertransporteinrichtung und, in einer zweiten Walzlinie ein paralleler Einlaufrollgang für die Kompakt-Tandemgerüstgruppe nachgeordnet sind, und das Horizontalgerüst der Vorwalzgruppe und/oder das Stauchzwischengerüst der Kompakt-Tandemgerüstgruppe jeweils zwei Wahlkaliber aufweisen, und daß dem ausgangsseitigen Universalgerüst der Kompakt-Tandemgerüstgruppe ein oder mehrere Duo-Horizontalgerüste mit Kalibervalzen nachgeordnet sind, und daß beim Walzen mit dieser Gerüstanordnung die Breitenanpassung und eine Formanpassung eines Vorprofils mit H-Querschnitt bei gleichzeitiger Reduzierung des Querschnitts in der Vorvalzgruppe und die weitere Reduzierung des Querschnitts mit Vorformung der Profilenden für die Schloßbildung in der Kompakt-Tandemgerüstgruppe und die abschließende Fertigbildung der Schlösser des Profils in den Kalibern der Duo-Horizontalgerüste erfolgt.This object is achieved in that the roughing group in one Rolling line has an outlet roller table and this a transverse transport device and, in a second rolling line, a parallel one Subordinate infeed roller table for the compact tandem scaffolding group are, and the horizontal stand of the roughing group and / or that Compression intermediate scaffolding of the compact tandem scaffolding group, two each Have caliber, and that the output-side universal frame the compact tandem scaffolding group one or more duo horizontal scaffolding are subordinate with caliber folds, and that when rolling with this scaffolding arrangement the width adjustment and a shape adjustment a pre-profile with an H cross-section while reducing of the cross-section in the prevalence group and the further reduction of the cross section with preforming of the profile ends for the lock formation in the compact tandem scaffolding group and the final completion the lock of the profile in the calibres of the duo horizontal frames he follows.
Mit dieser Ausbildung von Walzgerüsten und deren Betreibensweise lassen sich sowohl U-Profile mit stark variierenden Höhen als auch Z-Profile für Spundwände einschließlich der unterschiedlichen Schloßformen von deren Enden bei sehr guter Walzleistung herstellen.With this training of rolling stands and their mode of operation can be both U-profiles with widely varying heights as well Z profiles for sheet piling including the different ones Manufacture lock forms from their ends with very good rolling performance.
