Abstract
Description
Die Erfindung bezieht sich auf ein Arbeitsverfahren zum Walzen von Fertigprofilen gemäß dem Oberbegriff des Anspruchs 1 (siehe z.B. EP-A-0 653 253).The invention relates to a working method for rolling finished profiles according to the generic term of claim 1 (see e.g. EP-A-0 653 253).
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
Reversierwalzgerüste mit, die Vielzahl der Formkaliber aufnehmenden
großen Ballenlängen der Walzen erforderte (GB 2 037 205 A). 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 mill stands with the large number of form calibers
large bale lengths of the rollers required (
Man hat deshalb für das Walzen von Spundwandprofilen bereits in einer nicht vorveröffentlichten älteren Patentanmeldung vorgeschlagen, die anfangs genannte Walzgerüstanordnung zu verwenden, 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, und mit dieser 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, to use the initially mentioned roll stand arrangement, which consists 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 Choice caliber exists, and with this the preformed pre-profile in the possibly with 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 inclusion, a stitch in which, 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 Arbeits-Verfahren nach der genannten, nicht vorveröffentlichten Patentanmeldung zum Walzen von Spundwandprofilen so zu verbessern, daß die erwähnten Nachteile vermieden und die Schwierigkeiten beseitigt werden und damit das Walzen von Spundwandprofilen sowohl mit U-Querschnitt, als auch das von solchen mit Z-Querschnitt in allen Größenordnungen und mit guten Leistungen der Walzgerüstanordnung ermöglicht wird.The object of the invention is the working method after the aforementioned, not previously published patent application for rolling To improve sheet piling profiles so that the disadvantages mentioned avoided and the difficulties eliminated and thus 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 performances the roll stand arrangement is made possible.
Diese Aufgabe wird bei einem gattungsgemäßen Verfahren dadurch gelöst, daß 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 Kaliberwalzen 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 Vorwalzgruppe 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 a generic method in that 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 subordinated with caliber rollers, 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 roughing 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.
