Abstract
Description
Die Erfindung betrifft eine Walzanlage zum Walzen insbesondere von Flachstahl, mit wenigstens drei zu einem Walzblock zusammengefaßten Walzgerüsten, die zueinander um 90° winkelversetzte Walzenpaare aus glatten Walzen aufweisen, wobei die Walzenpaare einzeln antreibbar und symmetrisch zur Walzenachse anstellbar sind und die den Schmalseiten des Flachstahls zugeordneten Walzenpaare mit verstellbaren Walzgutführungen für die Breitseiten des Flachstahls zusammenwirken.The invention relates to a rolling system for rolling flat steel, in particular, with at least three rolling stands combined to form a rolling block, which have 90 ° offset pairs of rollers made of smooth rollers, the pairs of rollers being individually drivable and symmetrical to the axis of the roller and associated with the narrow sides of the flat steel Interacting roller pairs with adjustable rolling stock guides for the broad sides of the flat steel.
Um Stabstahl rechteckigen Querschnittes, sogenannter Flachstahl, der heute in großen Mengen und in den verschiedensten Querschnittsdimensionen benötigt wird, herzustellen, ist es bekannt, Walzgerüste zu kontinuierlichen Walzstraßen (DE-PS 916 165) oder kompakteren Walzblöcken (DE-OS 23 26723) aneinanderzureihen. Bei diesen Walzanlagen sind aber die Walzgerüste fest aufeinander abgestimmt und die Durchlaufrichtung des Walzgutes muß stets gleich bleiben.In order to produce steel bars with a rectangular cross-section, so-called flat steel, which is now required in large quantities and in a wide variety of cross-sectional dimensions, it is known to line up rolling stands to form continuous rolling trains (DE-PS 916 165) or more compact rolling blocks (DE-OS 23 26723). In these rolling mills, however, the rolling stands are firmly coordinated with one another and the direction in which the rolling stock passes must always remain the same.
Für jeden der vom Startquerschnitt bis zum Erreichen des Fertigquerschnittes notwendigen Walzstiche ist jeweils ein einzelnes Walzgerüst vorzusehen, durch welche Vielzahl von Walzgerüsten das Walzgut gegebenenfalls unter Wenden und Kippen in entsprechend langen Durchläufen hindurchgeführt werden muß. Es entstehen weit ausgedehnte Walzanlagen, die trotz ihres Bauaufwandes immer nur Stabstahl ganz bestimmten Querschnittes walzen können und für eine Änderung des Walzprogrammes umfangreichste Umrüstarbeiten voraussetzen. Außerdem kommt es durch die hohen Durchlaufzeiten zu einem frühzeitigen Erkalten des Walzgutes und zur Gefahr der Kantenbrüchigkeit, so daß Zwischenhitzen vorgesehen werden müssen, um Rißbildungen beim Walzen zu vermeiden.For each of the roll passes required from the starting cross-section to reaching the finished cross-section, a single roll stand is to be provided, through which plurality of roll stands the rolling stock may have to be passed in correspondingly long passes, with turning and tipping. This results in extensive rolling mills that, despite their construction costs, can only roll bar bars with a specific cross-section and require extensive retrofitting work to change the rolling program. In addition, due to the high throughput times, the rolled stock cools prematurely and there is a risk of edge breakage, so that intermediate heating must be provided in order to avoid cracking during rolling.
Es gibt auch bereits reversible Walzgerüste (DE-OS 22 54 6761 die aber ausschließlich als Einzelgerüste verwendet werden und sich immer nur zum Bearbeiten einer der beiden Seiten, also entweder die Breite oder die Höhe, eines Flachstahls eignen. Da die der anderen Seite zugeordneten Walzgutführungen nicht nach jedem Stich, sondern nur für eine Änderung des Walzprogrammes verstellbar sind, bleibt der Anwendungsbereich dieser Walzgerüste von vornherein beschränkt.There are already reversible rolling stands (DE-OS 22 54 6761) which are used exclusively as single stands and are only ever suitable for working on one of the two sides, that is either the width or the height, of a flat steel The range of application of these roll stands remains limited from the outset, not after each pass, but only for changing the rolling program.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Walzanlage zu schaffen, die sich durch ihren besonders geringen Platzbedarf auszeichnet, bei kompakter Bauweise kürzeste Durchlaufzeiten erlaubt, die rationelle Herstellung von Flachstahl gewährleistet und außerdem die Möglichkeit zum Walzen jeden Vierkants vom Quadrat bis zum extremen Rechteckquerschnitt ohne aufwendige Umrüstungen bietet.The invention is therefore based on the object to provide a rolling mill which is characterized by its particularly small space requirement, allows compact cycle times throughput times, ensures the rational production of flat steel and also the possibility of rolling every square from square to extreme right offers corner cross-section without complex conversions.
Die Erfindung löst diese Aufgabe dadurch, daß alle Walzgerüste reversibel sind, daß für sich symmetrisch zur Walzachse verstellbare Walzgutführungen vor und hinter den ihnen zugehörenden Walzenpaaren liegen und daß die Walzenantriebe, die Antriebe zur Walzenanstellung und die Antriebe zur Verstellung der Walzgutführungen nach jedem Durchlauf des Walzgutes durch den Walzblock mittels einer numerischen Steuerung im Sinne einer Durchlaufrichrungsumkehr zur fortgesetzten Querschnittsabnahme entsprechend einem bestimmten Walzprogramm ansteuerbar sind.The invention solves this problem in that all rolling stands are reversible, that rolling stock guides that are symmetrical to the rolling axis are located in front of and behind the associated pairs of rolls and that the roller drives, the drives for rolling adjustment and the drives for adjusting the rolling stock guides after each pass of the rolling stock can be controlled by the roll block by means of a numerical control in the sense of a reversal of the direction of travel for the continuous decrease in cross-section in accordance with a specific rolling program.
Durch diese Maßnahmen entsteht gewissermaßen eine kontinuierliche und reversible Walzstraße, auf der pro Durchlauf der Anzahl der Walzgerüste entsprechend viele Stiche gewalzt werden können. Die Reversibilität erlaubt darüber hinaus mit dieser Walzstraße allein beliebig viele Stiche vorzunehmen, wozu das Walzgut lediglich in entsprechender Durchlaufzahl in beiden Richtungen durch die Walzstraße geschickt werden muß. Die glatten, anstellbaren Walzenpaare und ihr jeweils 90°-iger Versatz lassen dabei das Walzen jedes rechtwinkeligen Vierkantquerschnittes zu und die Walzgutführungen verhindern sicher ein Kippen oder Ausweichen von Walzgut auch schmalster Querschnitte aus der Walzmitte, so daß vom Startknüppel bis zum beliebigen Flachquerschnitt wirklich alles auf dieser reversiblen Walzstraße herstellbar ist. Um die Walzgerüste nach jedem Walzgutdurchlauf umstellen und für eine fortgesetzte Bearbeitung bei geänderter Durchlaufrichtung aufeinander abstimmen zu können, werden die jeweiligen Antriebe und Verstelltriebe mittels einer numerischen Steuerung entsprechend der alternierenden Durchlaufrichtung und dem Bearbeitungsfortschritt angesteuert. Diese numerische Steuerung erlaubt die programmierbare Koordination und Überwachung der einzelnen Antriebe für die Walzen, die Walzenanstellung und auch die Walzgutführungen und gewährleistet bei einfacher Wahl verschiedener Walzprogramme jeweils einen exakten Walzvorgang. Dadurch ist eine Flachstahlherstellung in kürzester Zeit und auf rationellste Weise möglich und die ganze Walzanlage mit ihrem reversiblen Walzblock kann außerdem auf verhältnismäßig kleinem Raum untergebracht werden.These measures effectively create a continuous and reversible rolling mill, on which a large number of passes can be rolled per pass depending on the number of roll stands. The reversibility also allows any number of passes to be carried out with this rolling mill alone, for which purpose the rolling stock merely has to be sent through the rolling mill in both directions in a corresponding number of passes. The smooth, adjustable roller pairs and their 90 ° offset allow the rolling of every rectangular square cross-section and the rolling stock guides reliably prevent the rolling stock from tipping or evading even the narrowest cross-sections from the center of the roll, so that everything from the starting stick to any flat cross-section really does this reversible rolling mill can be produced. In order to be able to rearrange the rolling stands after each pass of the rolling stock and to be able to coordinate them with one another for continued processing with a changed direction of passage, the respective An drives and adjusting drives are controlled by means of a numerical control according to the alternating direction of passage and the processing progress. This numerical control allows the programmable coordination and monitoring of the individual drives for the rolls, the roll adjustment and also the rolling stock guides and guarantees an exact rolling process with a simple choice of different rolling programs. As a result, flat steel production is possible in the shortest possible time and in the most efficient manner, and the entire rolling mill with its reversible rolling block can also be accommodated in a relatively small space.

Die in Fig. 1 veranschaulichte Walzanlage besteht aus fünf zu einem gemeinsamen Walzblock 1 zusammengefaßten Wälzgerüsten 2, 3, von denen die Walzgerüste 2 jeweils ein horizontales Paar glatter Walzen 4 und die Walzgerüste 3 jeweils ein vertikales Paar glatter Walzen 5 aufweisen. Die Walzenpaare 4,5 sind unabhängig voneinander antreibbar, wobei jeder Antrieb aus einem Drehstrommotor 6, einer regelbaren Hydraulikpumpe 7 und einem über Hydraulikleitungen 8 mit dieser verbundenen Hydraulikmotor 9 besteht, welcher Hydraulikmotor über ein Getriebe 10 und Gelenkwellen 11 die Walzen 4, 5 in Drehung versetzt. Die Walzendrehzahl kann dabei durch Veränderung des Schwenkwinkels der Regelpumpe 7 stufenlos verändert werden und über diese Regelpumpe läßt sich auch die Drehrichtung der Walzen umkehren.The rolling mill illustrated in FIG. 1 consists of five rolling
Die Walzen 4, 5 sind in den Walzgerüsten 2, 3 anstellbar gelagert, wozu die Walzenlager 12 eines jedes Walzenpaares über Verstelltriebe 13 symmetrisch zur Walzmitte versetzbar sind. Die Verstelltriebe 13 werden über Hydraulikmotore 14 angetrieben, die mittels aufgebauter Hydraulikventile und einer Versorgungsleitung 15 von einer gemeinsamen, an einen Elektromotor 16 gekoppelte Hydraulikpumpe 17 versorgt werden.The
Um mit den glatten Walzen 4, 5 Flachprofile walzen zu können, sind den vertikalen Walzen 5 Walzgutführungen 18 zugeordnet, die für das Walzen der Schmalseiten des Flachstahls dessen Breitseiten führen und beim Walzen ein Kippen des Flachstahls verhindern. Zur Anpassung an verschiedene Querschnitte sind diese Walzgutführungen 18 in vertikaler Richtung verstellbar, welche Verstellung wiederum durch Hydraulikmotoren 19 erfolgt, die über Hydraulikventile an die Versorgungsleitung 15 und die Hydraulikpumpe 17 angeschlossen sind. Wie in den Fig. 2 und 3 angedeutet, bestehen die Walzgutführungen 18 jeweils aus zwei sich zu einem Rechteckquerschnitt 20 ergänzenden Winkelteilen 18', deren horizontale Führungsschenkel 18" zungenförmig weit in den Walzspalt vorragen und__zur Schonung der Walzgutoberfläche in nicht näher dargestellter Weise Rollen tragen können. Diese Winkelteile 18' sitzen in Vertikalführungen 21 und lassen sich mit einer Verstellwelle 22, die über ein Ritzel 23 mit einer an den Winkelteilen 18' befestigten Zahnstange 24 zusammenwirkt, in einander entgegengesetzter Richtung bewegen. Die Verstellwelle 22 ist dazu mit dem Hydraulikmotor 19 antriebsverbunden.In order to be able to roll with the
Der Walzblock 1 mit seinen horizontalen und vertikalen Paaren glatter Walzen 4, 5, den reversiblen Walzenantrieben sowie der Möglichkeit der Walzenanstellung und der verstellbaren Walzgutführungen 18 erlaubt pro Durchlauf die Durchführung mehrerer Stiche unmittelbar hintereinander und durch das Aneinanderreihen entgegengesetzt gerichteter Durchläufe das Walzen einer beliebigen Stichzahl und das Erreichen verschiedenster Flachquerschnitte. Eine numerische Steuerung 25, die über entsprechende Steuerleitungen 26, 27, 28 die Hydraulikpumpen 7 für die Walzenantriebe, die Hydraulikventile für die Hydraulikmotoren 14 zur Walzenanstellung und die Hydraulikventile für die Hydraulikmotoren 19 zur Verstellung der Walzgutführungen 18 ansteuert, übernimmt dabei in Abhängigkeit des von einem Kommandopult 29 aus eingegebenen Walzprogramms die Steuerung und Kontrolle der aufeinander abzustimmenden Regelgrößen, wie Walzendrehrichtung, Walzendrehzahl, Anstellmaß der Walzen und Verstellmaß der Walzgutführungen, so daß ein funktionssicherer Ablauf des Walzens von Flachstahl auf einem kompakten reversiblen Walzblock aus mehreren Walzgerüsten gewährleistet ist.The
