Description
Die Erfindung bezieht sich auf ein Walzwerk zum Walzen von Formstahl auf, in mehreren parallelen Walzlinien angeordneten Walzgerüsten, wie Universal-Walzgerüsten und Duo-Walzgerüsten, mit Längs- und Quer-Fördereinrichtungen für das Walzgut entlang einer Walzlinie bzw. von einer Walzlinie auf die andere Walzlinie, bei der einzelne der Walzgerüste aus einer Walz-Betriebsposition in andere Walz-Betriebspositionen in der gleichen oder in einer der anderen Walzlinien versetz- oder verschiebbar sind.The invention relates to a rolling mill for rolling shaped steel, in several parallel rolling lines arranged rolling stands, such as universal rolling stands and duo rolling stands, with longitudinal and transverse conveyors for the rolling stock along a rolling line or from one rolling line to the other Rolling line in which individual ones of the rolling stands can be moved or shifted from one rolling operating position into other rolling operating positions in the same or in one of the other rolling lines.
Ältere, z.T. auch neuere Vorschläge für Walzwerke dieser Bauart, bei der die ggfs. mehrere Walzgerüste in einer Achslinie gemeinsam angetrieben werden, und das Walzgut zunächst in einem Walzgerüst oder mehreren Walzgerüsten einer Walzlinie und dann nach Querverschiebung oder Umlenkung in den Walzgerüsten einer parallelen Walzlinie weitergewalzt wird, dienten bisher nur der Lösung einzelner spezieller Walzprobleme. So ist z.B. aus der DE-A1 14 52 150 ein Mitteleisenwalzwerk halbkontinuierlicher Bauart zum Auswalzen von Rundstählen und Profilstählen, einschließlich I-Profilen bekanntgeworden, das reversierend arbeitende Vor- und Zwischenwalzgerüste auf mehreren parallelen, durch Querschlepper vor und hinter den Zwischengerüsten verbundenen Walzlinien und ferner eine kontinuierliche Fertigstaffel umfaßt. Für das Walzen von I-Profilen werden in diesem Mitteleisenwalzwerk die dazu notwendigen Universal-Walzgerüste mit dem dazugehörigen Kantenstauchgerüst in der Walzlinie der Fertigstaffel angeordnet. Das erste Gerüst der Fertigstaffel und beide Universalgerüste sowie das Kantenstauchgerüst können dabei gegen Duo-Walzgerüste ausgetauscht werden.Older, partly Also newer proposals for rolling mills of this type, in which the possibly several rolling stands are driven together in one axis line, and the rolling stock is first rolled in a rolling stand or several rolling stands in one rolling line and then after transverse displacement or deflection in the rolling stands of a parallel rolling line so far only the solution of individual special rolling problems. For example, from DE-A1 14 52 150 a medium iron rolling mill of semi-continuous type for rolling out round steels and section steels, including I-profiles, has become known, the reversing working roughing and intermediate rolling stands on several parallel rolling lines connected by tractors in front of and behind the intermediate stands and also a continuous finishing line includes. For the rolling of I-sections, the necessary universal roll stands with the associated edging stand are arranged in the rolling line of the finishing train in this center iron rolling mill. The first stand of the finishing line and both universal stands as well as the edging stand can be exchanged for duo roll stands.
Inzwischen sind Walzwerksausbildungen bekanntgeworden (US-A 4,791,799), die aus dicht hintereinander angeordneten Universal-Walzgerüsten und Duo-Walzgerüsten bestehen und bei geringem Platzbedarf und hoher Leistung aufgrund der Eigenart dieser Gerüstanordnung insb. der verwendeten Universal-Walzgerüste nur ein kleines Formstahl-Profilprogramm walzen können und deshalb wegen der hohen Investitions- und Walzbetriebskosten, die solche sog. "Kompaktgerüste" mit sich bringen, eine hohe Produktion von Trägern oder anderem Formstahl ausbringen müssen.In the meantime, rolling mill designs have become known (US Pat. No. 4,791,799), which consist of universal rolling stands and duo rolling stands arranged closely one behind the other and with a small footprint and high output due to the nature of these The scaffolding arrangement, in particular of the universal rolling stands used, can only roll a small profile steel profile program and therefore, due to the high investment and rolling operating costs that such so-called "compact stands" entail, have to produce a high level of beams or other shape steel.
Ein Vorschlag, das Profilprogramm solcher Kompaktgerüste zu vergrößern (Firmenschrift SMS Schloemann-Siemag AG W2/3212 "Combined Section mill") erlaubte zwar die Verwendung einer begrenzten, häufig aber nicht ausreichenden Erhöhung der Zahl der zur Verfügung stehenden Profilkaliber; erforderte aber entsprechend größere Ballenlängen der Duo-Walzen, dementsprechend breitere Rollgänge und umfangreichere Quertransporteinrichtungen. Die großen Ballenlängen beeinträchtigten dabei wegen der unvermeidlichen Walzendurchbiegung auch die Steifigkeit der Gerüste. Um diesem Nachteil zu begegnen, wurden Walzgerüste mit veränderbarem Walzlagerabstand, d.h. verschiebbaren Walzenständern vorgeschlagen, die aber wiederum hohe Investitions- und für das jeweilige Umbauen hohe Betriebskosten, sowie einen beträchtlichen Zeitaufwand für das Umbauen mit sich brachten.A proposal to enlarge the profile range of such compact stands (SMS Schloemann-Siemag AG W2 / 3212 "Combined Section mill") allowed the use of a limited but often insufficient increase in the number of profile calibers available; but required correspondingly longer bale lengths for the duo rollers, correspondingly wider roller tables and more extensive transverse transport devices. The large bale lengths also affected the rigidity of the stands due to the inevitable roll deflection. In order to counter this disadvantage, roll stands with variable rolling bearing spacing, i.e. Slidable roller stands proposed, which in turn brought high investment and high operating costs for the respective conversion, as well as a considerable amount of time for the conversion.
Auch eine ebenfalls vorgeschlagene aber nicht druckschriftlich veröffentlichte Anordnung zusätzlicher Duo-Walzgerüste zur Erweiterung eines Produktionsprogramms in solchen Walzwerken brachte neben den dafür aufzubringenden Investitionskosten einen erheblichen zusätzlichen Platzbedarf mit sich und erforderte entsprechende Erhöhungen der Produktion, zumindest bestimmter Profile, wenn das tatsächlich walzbare Gesamt-Profil-Programm wirtschaftlich hergestellt werden sollte.An arrangement, which was also proposed but not published in writing, of additional duo roll stands for expanding a production program in such rolling mills, in addition to the investment costs involved, also required considerable additional space and required corresponding increases in production, at least certain profiles, if the actually rollable overall profile Program should be produced economically.
Schließlich ist noch eine aus mehreren nebeneinander angeordneten und gemeinsam angetriebenen Walzgerüsten bestehende, sog. offene Walzstraße bekanntgeworden (SU-A 806 167), bei der diese nebeneinander angeordneten Walzgerüste ortsfest angeordnet sind. Parallel zu diesen Gerüsten ist auf einer Verfahreinrichtung ein weiteres, für sich selbständig angetriebenes Walzgerüst angeordnet, das mit Hilfe dieser Verfahreinrichtung wahlweise in die jeweilige Walzlinie des einen oder des anderen der Walzgerüstreihen einfahr- und aus dieser wieder herausfahrbar ist. Schließlich ist in der Walzlinie einer der äußersten der Walzgerüstgruppen, ebenfalls ortsfest und für sich angetrieben, ein Vorgerüst angeordnet. Die durch die Anordnung der verschiedenen Walzgerüste gegebenen Parallelwalzlinien sind dabei mit Bezug auf die installierten Walzgerüste fest vorgegeben. Ein Austausch der einzelnen Walzgerüste oder die Wegnahme des einen oder des anderen Walzgerüstes aus der Linie ist nicht möglich. Ebensowenig eine Änderung des Antriebflusses, und auch das verfahrbare Walzgerüst läßt sich weder gegen eine der anderen Walzgerüste austauschen, noch besteht die Möglichkeit einer Änderung der Antriebsübertragung über die Walzlinien hinweg.Finally, a so-called open rolling mill consisting of a plurality of roll stands arranged side by side and jointly driven has become known (SU-A 806 167), in which these roll stands arranged side by side are arranged in a fixed position. Parallel to these stands, another independently driven rolling stand is arranged on a moving device, which can be moved into and out of the respective rolling line of one or the other of the rolling stand rows with the help of this moving device. Finally, a roughing stand is arranged in the rolling line of one of the outermost of the roll stand groups, also stationary and driven by itself. By arranging the different mill stands given parallel rolling lines are fixed with reference to the installed roll stands. It is not possible to replace the individual roll stands or to remove one or the other roll stand from the line. Neither does a change in the drive flow, and the movable roll stand cannot be exchanged for one of the other roll stands, nor is there any possibility of changing the drive transmission across the rolling lines.
Ausgehend von der anfangs erwähnten grundsätzlichen Ausbildungsform eines Walzwerkes zum Walzen von Formstahl auf in mehreren parallelen Walzlinien angeordneten Walzgerüsten, mit Längs- und Querfördereinrichtungen, bei der einzelne der Walzgerüste aus einer Walz-Betriebsposition in eine andere Walz-Betriebsposition in der gleichen oder in einer der anderen Walzlinien versetz-oder verschiebbar sind, liegt der Erfindung die Aufgabe zugrunde, für die bereits erwähnten Kompaktwalzwerke, die aus dicht hintereinander angeordneten Universal-Walzgerüsten und Duo-Walzgerüsten bestehen, und die bei geringem Platzbedarf und hoher Leistung aufgrund der Eigenart dieser Gerüstanordnung nur ein verhältnismäßig kleines Formstahl-Profilwalzprogramm zu walzen vermögen, die Möglichkeit des Walzens eines sehr breiten Profilprogramms bei immer noch vergleichsweise geringem Platzbedarf für das Walzwerk und entsprechend niedrigen Investitionsaufwendungen zu schaffen.Starting from the basic design form of a rolling mill for rolling shaped steel on rolling stands arranged in several parallel rolling lines, with longitudinal and transverse conveying devices, in which individual ones of the rolling stands move from one rolling operating position into another rolling operating position in the same or in one of the other rolling lines are displaceable or displaceable, the object of the invention is based on the compact rolling mills mentioned above, which consist of closely arranged universal rolling stands and duo rolling stands, and which require only little space and high performance due to the nature of this stand arrangement relatively small form steel profile rolling program can roll, the possibility of rolling a very wide profile program with still comparatively small space requirements for the rolling mill and correspondingly low investment costs.
Diese Aufgabe wird dadurch gelöst, daß eine, aus mindestens zwei Universal-Walzgerüsten mit einem Duo-Stauchgerüst gebildete Universal-Tandem-Kompaktwalzgerüstgruppe und dieser zugeordnete weitere Universal-Walzgerüste und Duo-Walzgerüste in einem, mindestens drei Walzlinien aufweisenden Walzwerk angeordnet und in der jeweiligen Walz-Betriebsposition mit fest an einer der beiden außen liegenden Walzlinien angeordneten Antriebsaggregaten quer über die Walzlinien hinweg, unmittelbar oder auch mittelbar über ein oder mehrere zwischengeschaltete Walzgerüste oder Übertragungswellenträger kuppelbar sind.This object is achieved in that a universal tandem compact rolling stand group formed from at least two universal rolling stands with a duo upsetting stand and associated further universal rolling stands and duo rolling stands are arranged in a rolling mill having at least three rolling lines and in the respective one Rolling operating position with drive units fixedly arranged on one of the two outer rolling lines, across the rolling lines, can be coupled directly or indirectly via one or more intermediate rolling stands or transmission shaft supports.
Dadurch wird eine Art Schachbrett geschaffen, das aus einer Reihe von parallelen Walzlinien besteht, auf dem die jeweils für das Walzen einer bestimmten Formstahl-Profilgruppe geeignete Walzgerüstgruppe durch entsprechendes Versetzen oder Verschieben modulartig zusammengestellt werden kann.This creates a kind of chess board, which consists of a series of parallel rolling lines, on which the rolling stand group, which is suitable in each case for the rolling of a specific shaped steel profile group, can be put together in a modular manner by appropriate displacement or displacement.
Diese so ausgebildete Walzwerksanlage erlaubt das Walzen einer außerordentlich breiten Palette von Profilen und die Anwendung von, dem jeweils gewünschten Walzprodukt angepaßten Arbeitsverfahren durch entsprechende Positionierung einer ausgewählten Gruppe vorhandener Walzgerüste und Zusatzeinrichtungen (Antriebsübertragung-, Längs-, Quer-, Förder- und Walzgutleiteinrichtungen) auf den vorhandenen parallelen Walzlinien.This rolling mill system designed in this way allows the rolling of an extraordinarily wide range of profiles and the use of work processes that are adapted to the respective desired rolled product by appropriate positioning of a selected group of existing roll stands and additional devices (drive transmission, longitudinal, transverse, conveyor and rolling stock guiding devices) the existing parallel rolling lines.
Wie die Erfindung weiter vorsieht, kann in der Hauptwalzlinie eine Universal-Tandem-Kompaktgerüstgruppe, in der zweiten Walzlinie können drei Duo-Walzgerüste und in der dritten Walzlinie ein Duo-Stauchgerüst angeordnet werden, wobei die Duo-Walzgerüste über die Walzgerüste der Universal-Tandem-Kompaktgerüstgruppe, und das Duo-Stauchgerüst über eine der Duo-Walzgerüste und ein Walzgerüst der Universal-Tandem-Kompaktgerüstgruppe mit dem jeweiligen Antriebsaggregat der Universal-Tandem-Kompaktgerüstgruppe kuppel- bzw. von diesen abkuppelbar sind.As the invention further provides, a universal tandem compact stand group can be arranged in the main rolling line, three duo stands in the second rolling line and a duo upsetting stand in the third rolling line, the duo stands above the universal tandem stands -Compact stand group, and the duo upsetting stand can be coupled or uncoupled from the universal tandem compact stand group with the respective drive unit of the universal tandem compact stand group via one of the duo rolling stands and a rolling stand.
Mit dieser erfindungsgemäßen Ausbildung von Walzwerken zum Walzen von Formstahl kann die Anzahl der möglichen Profilwalzkaliber im gewünschten Ausmaß erhöht werden oder es können auch zusätzliche Fertigkaliber für die Duo-Profilwalzung vorgesehen werden. Beim Walzen von Schienen im Universal-Walzverfahren kann ein zusätzlicher Vorprofilstich (leader pass), oder es können ein oder mehrere Stauch-Stiche zusätzlich durchgeführt werden. Weiter können, ohne Einsetzen eines Duo-Vorwalzgerüstes, kleine Stranggußquerschnitte oder mittels eines zugeordneten Duo-Vertikalstauchgerüstes Stranggußquerschnitte zunächst angepaßt und dann unmittelbar der Universalwalzung zugeführt werden. Durch das Versetzen von Gerüsten insb. der Universalwalzgerüste von einer Position in die andere und auch für das Auswechseln von Walzensätzen eignen sich vorteilhaft Gerüste, die das Ausheben der Walzensätze aus den Gerüsten nach oben erlauben.With this inventive design of rolling mills for rolling shaped steel, the number of possible profile rolling calibers can be increased to the desired extent or additional finished calibers can also be provided for the duo profile rolling. When rolling rails in the universal rolling process, an additional pre-profile stitch (leader pass) or one or more upsetting stitches can be carried out. Furthermore, without inserting a duo roughing stand, small continuous casting cross sections or by means of an assigned duo vertical upsetting stand, continuous casting cross sections can first be adapted and then fed directly to the universal rolling. By moving stands, in particular the universal roll stands, from one position to the other and also for replacing roll sets, stands are advantageously suitable which allow the roll sets to be lifted out of the stands.
Die erfindungsgemäße Ausbildung erlaubt es ferner, bestehende Walzwerke schrittweise auf die erfindungsgemäße Anordnung um- und auszubauen und so das Walzen eines erheblich breiteren Profilprogramms zu ermöglichen.
Auf einem solchen Walzwerk können auch Träger in der Weise gewalzt werden, daß alle Walzstiche einschließlich des Leitstichs bei Antriebsabkupplung aller übrigen Walzgerüste auf der Universal-Tandem-Kompaktgerüstgruppe in der Hauptwalzlinie durchgeführt werden. Wird die Anordnung der Walzgerüste in dem Kompaktwalzwerk z.B. durch Umsetzung und Positionierung eines der Universal-Walzgerüste aus der Hauptwalzlinie in die dritte Walzlinie und Einsetzen eines Übertragungs-Wellenträgers in die bisherige Position dieses Universal-Walzgerüstes geändert, dann können auf dieser Ausbildung des Kompaktwalzwerks für das Profilwalzen, insb. von Spundbohlen die einzelnen Walzschritte darin bestehen, daß die ersten schweren Formstiche reversierend auf dem in der Hauptwalzlinie verbleibenden Universal-Walzgerüst und dem Duo-Stauchgerüst, die folgenden Formstiche auf dem in die dritte Walzlinie versetzten Universalgerüst, dem dort befindlichen Duo-Stauchgerüst, und die Fertigstiche kontinuierlich aufeinanderfolgend auf den fest kalibrierten drei Duo-Walzgerüsten in der zweiten Walzlinie durchgeführt werden.The design according to the invention also allows existing rolling mills to be converted and expanded step by step to the arrangement according to the invention and thus to enable the rolling of a considerably wider profile program.
Beams can also be mounted on such a rolling mill are rolled in such a way that all pass passes including the guide pass when the drive is disconnected from all other roll stands are carried out on the universal tandem compact stand group in the main rolling line. If the arrangement of the rolling stands in the compact rolling mill is changed, e.g. by moving and positioning one of the universal rolling stands from the main rolling line into the third rolling line and inserting a transmission shaft carrier into the previous position of this universal rolling stand, then the compact rolling mill can be used for this purpose Profile rolling, especially of sheet piles, the individual rolling steps consist in the fact that the first heavy form passes reversing on the universal rolling stand and the duo compression stand remaining in the main rolling line, the following form passes on the universal stand placed in the third rolling line, the duo located there Compression mill, and the finishing stitches are carried out continuously in succession on the permanently calibrated three duo mill stands in the second rolling line.
Das erfindungsgemäße Kompaktwalzwerk kann auch für das thermo-mechanische Walzen, d.h. Vorwalzen bei normalen Temperaturen von etwa 1100 bis 1000°C und Endverformung mit Abnahmen zwischen 30 und 40% bei einer Temperatur von 800°C und weniger zur Erreichung bestimmter Gefügeeigenschaften, ausgebildet und verwendet werden. Der jeweilig vorverformte Walzgutstab wird dabei während der Vorverformung des folgenden Walzgutstabes einer Querfördereinrichtung zugeführt, auf dieser abgelegt, natürlicher oder zusätzlicher Luft- und/oder Wasserkühlung ausgesetzt und auf einen vorgegebenen Wert abgekühlt, bspw. beim Walzen von Trägern in der Weise, daß der vorgewalzte Träger vor dem Fertig-Stich durch eine Quer-Transporteinrichtung von der der Universal-Tandem-Kompaktgerüstgruppe zugeordneten Längsfördereinrichtung abgenommen und auf dieser Quer-Fördereinrichtung bis zur Fertigwalzung des folgenden Trägers abgelegt, gekühlt, mit der Abnahme des folgenden Trägers durch die Quer-Fördereinrichtung von dieser auf eine Längs-Fördereinrichtung der zweiten Walzlinie übergeben und von einer zweiten Quer-Fördereinrichtung auf eine Längs-Fördereinrichtung der Hauptwalzlinie zurücktransportiert um, auf der Universal-Tandem-Kompaktgerüstgruppe fertiggewalzt zu werden.The compact rolling mill according to the invention can also be designed and used for thermo-mechanical rolling, ie roughing at normal temperatures of about 1100 to 1000 ° C and final deformation with decreases between 30 and 40% at a temperature of 800 ° C and less to achieve certain structural properties will. The respective preformed rolled stock is fed to a cross conveyor during the preforming of the following rolled stock, placed on it, exposed to natural or additional air and / or water cooling and cooled to a predetermined value, for example when rolling beams in such a way that the pre-rolled one Carrier removed from the longitudinal conveyor device assigned to the universal tandem compact scaffolding group by means of a transverse transport device before the finished stitch and placed on this cross conveyor until the next carrier is finished-rolled, cooled, with the removal of the following carrier by the cross conveyor from this to a longitudinal conveyor of the second rolling line and from a second cross conveyor to a longitudinal conveyor the main rolling line to be finished rolled on the universal tandem compact stand group.
Weitere Ausbildungsformen des erfindungsgemäßen Kompaktwalzwerks sind in den Unteransprüchen niedergelegt und in der nachfolgenden Beschreibung anhand der Zeichnung näher erläutert.Further forms of training of the compact rolling mill according to the invention are set out in the subclaims and explained in more detail in the following description with reference to the drawing.

Fig. 1 zeigt ein Kompaktwalzwerk mit drei Walzlinien. In der Hauptwalzlinie HWL sind hier die beiden Universalgerüste U1 und U2 und zwischen diesen ein Duo-Stauchgerüst E1 angeordnet. Beide Universalgerüste U1 und U2 werden von den Antriebsaggregaten A1 bzw. A2 und das Duo-Stauchgerüst E1 von dem Antriebsaggregat A3 über Kupplungen KH angetrieben. In der parallelen zweiten Walzlinie WLII sind, hier mit gleichem Abstand voneinander Duo-Walzgerüste DW1, DW2 und DW3 angeordnet, die mit den jeweiligen Universal-Walzgerüsten U1, U2 bzw. dem Duo-Stauchgerüst E1 über Kupplungen KII antriebskuppelbar sind. Diese Kupplungen KII befinden sich hier im entkuppelten Zustand. In der dritten Walzlinie WLIII ist in Achslinie mit dem mittleren der Duo-Walzgerüste DW2 in der zweiten Walzlinie WLII ein Duo-Stauchgerüst E2 angeordnet, das über eine Kupplung KIII mit dem mittleren Duo-Walzgerüst DW2 gekuppelt ist. In der gezeigten Anordnung wird das Kompaktwalzwerk zum Walzen von Trägern verwendet, bei dem sämtliche Stiche bis zum Fertig-Stich FS in der Hauptwalzlinie HWL auf den Universal-Walzgerüsten U1, U2 und dem zwischen diesem befindlichen Duo-Stauchgerüst E1 reversierend durchgeführt werden, wobei die übrigen der angeordneten Walzgerüste DW1, DW2, DW3 und E2 von den Antriebsaggregaten A1, A3 und A2 abgekuppelt bleiben.Fig. 1 shows a compact rolling mill with three rolling lines. The two universal stands U1 and U2 and between them a duo-upsetting stand E1 are arranged in the main rolling line HWL. Both universal stands U1 and U2 are powered by the drive units A1 and A2 and the duo edging stand E1 by the drive unit A3 driven via couplings KH. In the parallel second rolling line WLII, here, with the same distance from each other, there are duo roll stands DW1, DW2 and DW3, which can be coupled to the respective universal roll stands U1, U2 or the duo upsetting stand E1 via couplings KII. These couplings KII are here in the uncoupled state. In the third rolling line WLIII, a duo upsetting stand E2 is arranged in the axis line with the middle of the duo mill stands DW2 in the second rolling line WLII, which is coupled to the middle duo mill stand DW2 via a coupling KIII. In the arrangement shown, the compact rolling mill is used for rolling beams, in which all the passes up to the finished pass FS in the main rolling line HWL on the universal rolling stands U1, U2 and the duo-upsetting stand E1 located between them are carried out in a reversing manner, the Remaining of the arranged mill stands DW1, DW2, DW3 and E2 remain uncoupled from the drive units A1, A3 and A2.
Aus Fig. 2 geht eine Abänderung der Anordnung der Walzgerüste gem. Fig. 1 hervor; hier wurde das Universal-Walzgerüst U2 mit Hilfe eines Krans aus seiner Position in der Hauptwalzlinie in eine Position in der gleichen Achslinie in der dritten Walzlinie WLIII eingesetzt und in die bisherige Position des Universal-Walzgerüstes U2 in der Hauptwalzlinie ein Übertragungs-Wellenträger UW eingesetzt. Alle zwischen den einzelnen Walzgerüsten befindlichen Kupplungen KH, KII und KIII befinden sich bei dieser Anordnung im gekuppelten Zustand, so daß die Antriebskräfte der drei Antriebsaggregate A1, A2, A3 an der Hauptwalzlinie HWL auf die einzelnen Gerüste in den drei Walzlinien HWL, WLII und WLIII übertragen werden. Diese Anordnung der Walzgerüste in der Kompaktwalzstraße dient dem Walzen von Spundbohlen. Es werden dabei (vgl. Fig. 3) zunächst auf dem in der Hauptwalzlinie HWL verbliebenen Universal-Walzgerüst U1 und dem Stauchgerüst E1, ausgehend von einem Stranggußquerschnitt oder einem Vorwalzquerschnitt die ersten (vier) Formstiche reversierend durchgeführt, das Walzgut anschließend über einen (nicht dargestellten) Querschlepper in die dritte Walzlinie WLIII eingebracht, dort mit weiteren (zwei) reversierenden Formstichen auf den im wesentlichen fertigen Spundbohlen-Querschnitt gebracht und anschließend, nach Querschleppen auf die zweite Walzlinie WLII in den dort angeordneten, fest kalibrierten Duo-Walzgerüsten DW1, DW2 und DW3 mit sogen. "Klapp-Stichen" fertiggewalzt.From Fig. 2 is a change in the arrangement of the rolling stands acc. Fig. 1 shows; Here, the universal rolling stand U2 was used with the help of a crane from its position in the main rolling line to a position in the same axis line in the third rolling line WLIII, and a transmission shaft support UW was inserted in the previous position of the universal rolling stand U2 in the main rolling line. With this arrangement, all the couplings KH, KII and KIII located between the individual rolling stands are in the coupled state, so that the driving forces of the three drive units A1, A2, A3 on the main rolling line HWL on the individual stands in the three rolling lines HWL, WLII and WLIII be transmitted. This arrangement of the rolling stands in the compact rolling mill is used to roll sheet piles. It will (see Fig. 3) first on the in the main rolling line HWL remaining universal rolling stand U1 and the upsetting stand E1, starting from a continuous casting cross section or a roughing cross section, reversing the first (four) form passages, then the rolling stock was introduced into the third rolling line WLIII via a cross tractor (not shown), there with further (two) reversing form passes to the essentially finished sheet pile cross-section and then, after towing, onto the second rolling line WLII in the permanently calibrated duo mill stands DW1, DW2 and DW3 with so-called. Finished rolled "folding stitches".
Die Anordnung der Walzgerüste des in Fig. 4 dargestellten Kompaktwalzwerks entspricht der Anordnung nach Fig. 1 und ist ebenfalls für das Walzen von Trägern bestimmt. Die Träger können auf dieser Anordnung auch nach dem thermo-mechanischen Walzverfahren, wie bereits anfangs erläutert, gewalzt werden. Das aus dem Wärmofen WO kommende Walzgut wird über den Längsförderer LF1 der Universal-Tandem-Kompaktgerüstgruppe in der Hauptwalzlinie HWL, die aus den beiden Universal-Walzgerüsten U1 und U2 mit dem dazwischen angeordneten Stauchgerüst E1 besteht, zugeführt. Es besteht natürlich auch die Möglichkeit, das Walzgut, direkt aus einer Stranggußeinrichtung kommend dieser Gruppe zuzuführen, ggfs. nach einer vorbereitenden Vorverformung des Querschnittes in einem oder mehreren Duo-Vorgerüsten die bspw. in der zweiten Walzlinie WLII angeordnet sein könnten.The arrangement of the rolling stands of the compact rolling mill shown in FIG. 4 corresponds to the arrangement according to FIG. 1 and is also intended for the rolling of beams. The supports can also be rolled on this arrangement using the thermo-mechanical rolling method, as already explained at the beginning. The rolling stock coming from the heating furnace WO is fed via the longitudinal conveyor LF1 to the universal tandem compact stand group in the main rolling line HWL, which consists of the two universal roll stands U1 and U2 with the upsetting stand E1 arranged in between. Of course, there is also the possibility of feeding the rolling stock, coming directly from a continuous casting device, to this group, if necessary after preparatory pre-deformation of the cross-section in one or more duo roughing stands, which could be arranged, for example, in the second rolling line WLII.
Der in unterbrochenen Linien dargestellte Träger TR1 wird dabei, hier in zehn Stichen, in der Hauptwalzlinie HWL vorgewalzt und dann, auf dem Längsförderer LF2 liegend vom Querförderer QF2 übernommen und auf diesem abgelegt, bis der folgende, strichpunktiert angedeutete Träger TR2 die entsprechende Vorwalzung erfahren hat und ebenfalls von dem Querförderer QF2 übernommen wird, der dabei den vorhergehenden Träger TR1 auf den Längsförderer LF3 in der zweiten Walzlinie WLII übergibt, der diesen Träger TR1 an den in der gleichen Walzlinie befindlichen Längsförderer LF4 abgibt. Von diesem wird der Träger TR1 mittels des Querschleppers QF1 wieder in die Hauptwalzlinie HWL auf den Längsförderer LF1 gebracht, der den Träger TR1 für den Fertig-Stich der Gerüstgruppe U1, E1, U2 zuführt. Nach erfolgtem Fertig-Stich verläßt dann der Träger TR1 über den Längsförderer LF2 die Kompaktwalzstraße. Das Ablegen des jeweiligen Trägers zur Kühlung bzw. Kühlbehandlung kann auch statt auf dem Querförderer QF2 auf dem Querförderer QF1 erfolgen, wenn dies für den Ablauf der Stichfolge zweckmäßiger erscheint. Für solche Zwischenschritte können auch neben den beiden Längsförderern LF3 und LF4 noch der zur dritten Walzlinie WLIII führende Querförderer QF4 verwendet werden.The carrier TR1 shown in broken lines is pre-rolled here in ten passes in the main rolling line HWL and then, lying on the longitudinal conveyor LF2, taken over by the cross conveyor QF2 and placed on it until the following carrier TR2, indicated by broken lines, has undergone the corresponding roughing and also from that Cross conveyor QF2 is taken over, which in this case transfers the previous carrier TR1 to the longitudinal conveyor LF3 in the second rolling line WLII, which delivers this carrier TR1 to the longitudinal conveyor LF4 located in the same rolling line. From there, the carrier TR1 is brought back into the main rolling line HWL on the longitudinal conveyor LF1 by means of the cross tractor QF1, which feeds the carrier TR1 for the finishing pass to the stand group U1, E1, U2. After the finished stitch has been carried out, the carrier TR1 then leaves the compact rolling mill via the longitudinal conveyor LF2. The respective carrier for cooling or cooling treatment can also be placed on the cross conveyor QF1 instead of on the cross conveyor QF2 if this appears more expedient for the sequence of the sequence. In addition to the two longitudinal conveyors LF3 and LF4, the cross conveyor QF4 leading to the third rolling line WLIII can also be used for such intermediate steps.
Für das thermo-mechanische Walzen von Spundbohlen kann eine Walzgerüstanordnung verwendet werden, die der Anordnung nach Fig. 2 entspricht und hier in Fig. 5 dargestellt ist. Das Walzgut mit vorgegossenem oder vorgeformtem Querschnitt gelangt über den Längsförderer LF1 in die in der Hauptwalzlinie HWL positionierte, aus dem Universal-Walzgerüst U1 und dem Stauchgerüst E1 bestehende Walzgerüstgruppe, wird darauf in, hier vier Stichen vorgewalzt und von dem Längsförderer LF1 durch den Querförderer QF2 als in vollen Linien dargestellte vorgeformte Spundbohle SB1 auf diesem Querförderer QF 2 abgelegt. Während die nächste Spundbohle SB2 auf der gleichen Walzgerüstgruppe gewalzt und abschließend als - in unterbrochenen Linien dargestellte - Spundbohle SB2 von dem Querförderer QF2 übernommen wird, der dann die inzwischen kontrolliert abgekühlte vorgeformte Spundbohle SB1 dem von der zweiten Walzlinie WLII auf die dritte Walzlinie WLIII transportierenden Querförderer QF4 übergibt, der diese auf den in der dritten Walzlinie WLIII befindlichen Längsförderer LF5 ablegt, der die Spundbohle SB1 der aus dem Stauchgerüst E2 und dem Universal-Walzgerüst U2 bestehenden Walzgerüstgruppe in dieser Walzlinie WLIII zuführt; sie erfährt dort zwei weitere Formstiche und wird anschließend wieder durch den Querförderer QF4 von dem Längsförderer LF5 abgenommen und von dem Längsförderer LF4 in der zweiten Walzlinie WLII übernommen, der die Spundbohle SB1 der in dieser Walzlinie befindlichen Duo-Walgerüstgruppe DW1, DW2 und DW3 zuführt, in der diese vorgeformte Spundbohle SB1 kontinuierlich fertiggewalzt und über den Längsförderer LF3 abtransportiert wird. Die Abkühlung der Spundbohlen findet bei dieser Anordnung auf dem Querförderer QF2 zwischen der Hauptwalzlinie HWL und der zweiten Walzlinie WLII statt.A roll stand arrangement which corresponds to the arrangement according to FIG. 2 and is shown here in FIG. 5 can be used for the thermo-mechanical rolling of sheet piles. The rolling stock with a pre-cast or pre-shaped cross-section passes via the longitudinal conveyor LF1 into the rolling stand group consisting of the universal rolling stand U1 and the upsetting stand E1, which is positioned in the main rolling line HWL, is then pre-rolled in four passes and is then pre-rolled by the longitudinal conveyor LF1 through the cross conveyor QF2 as pre-formed sheet pile SB1 shown in full lines on this
Die Ausbildung der Kompaktwalzstraße nach Fig. 6 unterscheidet sich von der beschriebenen nach Fig. 5 durch ein zusätzlich in die zweite Walzlinie WLII in Achslinie mit einem der beiden Universal-Walzgerüste in der Hauptwalzlinie HWL positioniertes Duo-Walzgerüst DW4 auf dem der (die) Steg-Fertigstich(e) ausgeführt wird (werden). Die vorhergehenden Walz-Stiche des ersten gewalzten Trägers TR1, in unterbrochenen Linien dargestellt werden wie zu Fig. 4 beschrieben auf der Universal-Tandem-Kompaktgerüstgruppe U1, E1 und U2 in der Hauptwalzlinie HWL durchführt. Anschließend wird der Träger TR1 noch vom Längsförderer LF2 durch den Querförderer QF2 abgenommen und verbleibt auf diesem bis der nächste Träger TR2, strichpunktiert dargestellt, die entsprechende Stichzahl erfahren hat und in der gleichen Weise vom Querförderer QF2 übernommen und dabei gleichzeitig der auf dem Querträger QF2 liegende vorangegangene Träger TR1 auf den Längsförderer LF3 in der zweiten Walzlinie WLII übergeben und in dieser Walzlinie auf dem Duo-Walzgerüst DW4 den (die) Fertigstich(e) erfährt (erfahren). Die Anordnung erlaubt es, die Träger je nach Stichzahl entweder auf dem einen oder dem anderen der beiden den Längsförderern LF1 und LF2 der Hauptwalzlinie HWL zugeordneten Querförderer QF1 bzw. QF2 abzulegen und dort zu kühlen und diesen Träger dann auf den einen oder den anderen der beiden Längsförderer LF3 bzw. LF4 der zweiten Walzlinie WLII zu übergeben und mit einem Fertig-Stich aus der einen oder der anderen Richtung fertigzuwalzen; dies geschieht hier beim Duo-Walzgerüst DW4 mit einer Ausbildung als Duo-Horizontalgerüst mit dem das Endmaß des Trägersteges eingewalzt wird, während bei der entsprechenden Ausbildung dieses Duo-Walzgerüstes 4′ gem. Fig. 7 als Vertikalgerüst das Endmaß der Flanschdicke eingewalzt werden kann. Es besteht natürlich auch die Möglichkeit, anstelle solcher unterschiedlicher Duo-Walzgerüste ein Universal-Walzgerüst zu verwenden, wenn die betrieblichen Verhältnisse dies gestatten.The design of the compact rolling mill according to FIG. 6 differs from that described according to FIG. 5 by an additional dual rolling mill DW4 positioned on the the web (s) in the second rolling line WLII in the axial line with one of the two universal rolling stands in the main rolling line HWL -Finished stitch (s) is (will be) executed The preceding rolling passes of the first rolled carrier TR1, shown in broken lines, are carried out as described in relation to FIG. 4 on the universal tandem compact stand group U1, E1 and U2 in the main rolling line HWL. Subsequently, the carrier TR1 is still removed from the longitudinal conveyor LF2 by the cross conveyor QF2 and remains there until the next carrier TR2, shown in dash-dotted lines, has received the corresponding number of stitches and has been taken over in the same way by the cross conveyor QF2 and at the same time the one lying on the cross carrier QF2 Transfer the previous carrier TR1 to the longitudinal conveyor LF3 in the second rolling line WLII and experience the finished stitch (s) in this rolling line on the duo mill stand DW4. The arrangement allows depending on the number of stitches, either place the supports on one or the other of the two cross conveyors QF1 or QF2 assigned to the longitudinal conveyors LF1 and LF2 of the main rolling line HWL and cool them there and then this carrier on one or the other of the two longitudinal conveyors LF3 or LF4 to be handed over to the second rolling line WLII and finished with one finish stitch from one direction or the other; this is done here with the DW4 double mill stand with training as a duo horizontal stand with which the final dimension of the girder web is rolled in, while with the corresponding training of this dual roll stand 4 'acc. Fig. 7 as a vertical stand, the final dimension of the flange thickness can be rolled. Of course, it is also possible to use a universal roll stand instead of such different duo roll stands if the operating conditions allow it.
Sollen mit dem Kompaktwalzwerk Schienen gewalzt werden, dann kann dies bspw. in an sich bekannter Weise, wie aus Fig. 8 zu ersehen mit Hilfe einer in einer Walzlinie, zweckmäßig der Hauptwalzlinie HWL positionierten Universal-Tandem-Kompaktgerüstgruppe U1, E1 und U2 geschehen, der ein Duo-Stauchgerüst DW5 in nahem Abstand vorpositioniert ist.

Jedem dieser Walzgerüste U2, U3 und U1 ist ein Duo-Stauchgerüst E1, E2 bzw. E3 vor- bzw. nachgeordnet. Die Anordnung erlaubt es, das vorprofilierte Profil in der Hauptwalzlinie HWL mit einem Universal-Stich US1 im Universal-Walzgerüst U2 und einem diesem folgenden Stauch-Stich ST2 auf dem Duo-Stauchwalzgerüst E1 in der gleichen Walzlinie zu walzen, dem reserviert ein Leer-Stich LS im gleichen Gerüst und diesem ein zweiter Universal-Stich US2 auf dem genannten Universal-Walzgerüst U2, reservierend ein dritter Universal-Stich US3 auf dem gleichen Gerüst und diesem einem Leer-Stich LS auf dem Duo-Stauchgerüst E1 folgen. Nach Querförderung des Walzgutes aus der Hauptwalzlinie HWL in die zweite Walzlinie WLII werden aufeinanderfolgend ein Stauchstich ST2 im Duo-Stauchgerüst E2 und ein Universal-Stich US4 im Universal-Walzgerüst U3 gefahren, denen nach erneutem Querfördern des Walzgutes von der zweiten Walzlinie WLII in die dritte Walzlinie WLIII ein weiterer Stauch-Stich ST3 im Duo-Stauchgerüst E3 und der Fertig-Stich FS als Universal-Stich US5 in dem Universal-Walzgerüst U1 folgen. Die Anordnung der Walzgerüste nach Fig. 15 und die auf diesem zu fahrenden Stich-Folgen entsprechen spiegelbildlich angeordnet und verlaufend denen nach Fig. 14.14 and 15, a universal rolling stand U2 in the main rolling line HWL, U3 in the second rolling line WLII and U1 in the third rolling line WLIII are positioned in all three rolling lines. Each of these roll stands U2, U3 and U1 is preceded or followed by a duo upsetting stand E1, E2 and E3. The arrangement allows the pre-profiled profile to be rolled in the main rolling line HWL with a universal pass US1 in the universal mill stand U2 and a subsequent straight pass ST2 on the duo edging mill stand E1 in the same rolling line, which is reserved by an empty pass LS in the same stand and this a second universal pass US2 on the mentioned universal rolling stand U2, reserving a third universal pass US3 on the same stand and following this with an empty pass LS on the duo edging stand E1. After cross-conveying of the rolling stock from the main rolling line HWL to the second rolling line WLII, an upsetting stitch ST2 in the duo-upsetting stand E2 and a universal stitch US4 in the universal rolling stand U3 are moved, which, after another cross-conveying of the rolling stock, from the second rolling line WLII to the third Rolling line WLIII is followed by a further upsetting stitch ST3 in the duo upsetting stand E3 and the finished stitch FS as a universal stitch US5 in the universal rolling mill U1. The arrangement of the rolling stands according to FIG. 15 and the stitch sequences to be driven on them correspond to each other in a mirror-inverted manner and in the same way as those according to FIG.
Die Anordnung der Walzgerüste des Kompaktwalzwerkes nach Fig. 16 ähnelt der Anordnung nach Fig. 15 mit dem Unterschied, daß in der Hauptwalzlinie HWL nur noch ein Universal-Walzgerüst U2 positioniert ist. Das von einer Stranggußanlage kommende vorgegossene oder auch anschließend noch vorgewalzte Profil PR wird in der Hauptwalzlinie HWL auf dem Universal-Walzgerüst U2 mit drei reversierenden Universal-Stichen (US1, US2 und US3) vorgewalzt, dann über einen Querförderer der zweiten Walzlinie WLII zugeführt und dort auf dem Duo-Stauchgerüst E1 einem Stauch-Stich als Leit-Stich LT unterworfen, dem ein weiterer Universal-Stich US4 auf dem Universal-Walzgerüst U1 der gleichen Walzlinie folgt. Diesem Stich folgt reversierend ein weiterer Universal-Stich US5 auf dem gleichen Universalgerüst, ein Leer-Stich LS durch das Duo-Stauchgerüst E1 der gleichen Walzlinie und reversierend ein erster Stauch-Stich ST1 auf diesem Duo-Universalgerüst E1, dem ein weiterer Universal-Stich US6 auf dem Universal-Walzgerüst U1 dieser Walzlinie folgt. Nach Querförderung des Walzgutes auf die dritte Walzlinie WLIII wird das Walzgut nach einem Stauch-Stich ST2 auf dem Duo-Stauchgerüst E2 dieser Walzlinie mit dem Universal-Walzgerüst U3 in einem Universal-Stich US7 fertiggewalzt.The arrangement of the roll stands of the compact rolling mill according to FIG. 16 is similar to the arrangement according to FIG. 15, with the difference that only one universal roll stand U2 is positioned in the main rolling line HWL. The pre-cast or pre-rolled profile PR coming from a continuous casting plant is pre-rolled in the main rolling line HWL on the universal roll stand U2 with three reversing universal passes (US1, US2 and US3), then fed to the second rolling line WLII via a cross conveyor and there on the duo edging stand E1 subjected to an upset stitch as the leading stitch LT, which is followed by another universal pass US4 on the universal rolling stand U1 of the same rolling line. This stitch is followed reversibly by another universal US5 stitch on the same universal stand, an empty stitch LS by the duo edging stand E1 of the same rolling line and reversing a first upsetting stitch ST1 on this duo universal stand E1, which is another universal stitch US6 on the universal rolling stand U1 follows this rolling line. After transverse conveyance of the rolling stock on the third rolling line WLIII, the rolling stock is finished rolled after a upsetting pass ST2 on the duo upsetting stand E2 of this rolling line with the universal rolling stand U3 in a universal pass US7.
Die Ausbildung des Kompaktwalzwerkes nach Fig. 17 unterscheidet sich von der Ausbildung nach Fig. 16 nur dadurch, daß in der Hauptwalzlinie HWL ein Universal-Walzgerüst U2′ angeordnet ist, das zwei Kaliber aufweist. Der erste und der reversierende zweite Universal-Stich werden durch das erste Kaliber K1 des Universal-Walzgerüstes U2′ geführt, wobei der Schienenfußbereich von einer Vertikalwalze VW des Gerüstes beaufschlagt wird. Der nächste Stich, der gleichzeitig der Leit-Stich LT ist, findet auf dem gleichen Gerüst im zweiten Kaliber K2 statt und stellt im Ergebnis einen Stauch-Stich dar, da die Vertikalwalze VW des Universal-Walzgerüstes U2′ bei diesem Stich nicht in Aktion tritt. Nach Querförderung in die zweite Walzlinie WLII folgt dann anstelle des ersten Stauch-Stiches im Duo-Stauchgerüst E1 nach der vorangegangenen Darstellung ein Leer-Stich durch dieses Gerüst, und die anschließenden Stiche entsprechen denen der Anordnung und der Stichfolgen-Angabe nach Fig. 16.The design of the compact rolling mill according to FIG. 17 differs from the design according to FIG. 16 only in that a universal roll stand U2 'is arranged in the main rolling line HWL, which has two calibers. The first and the reversing second universal stitch are passed through the first caliber K1 of the universal rolling stand U2 ', the rail foot area being acted upon by a vertical roller VW of the stand. The next stitch, which is also the master stitch LT, takes place on the same stand in the second caliber K2 and represents a upsetting stitch as the vertical roll VW of the universal roll stand U2 ′ does not take action on this stitch. After transverse conveying into the second rolling line WLII, instead of the first upsetting stitch in the duo-upsetting stand E1, an empty stitch follows through this stand according to the previous illustration, and the subsequent passes correspond to those of the arrangement and the sequence of steps according to FIG. 16.
Bei der Ausbildung des Kompaktwalzwerkes nach Fig. 18 ist dem Universal-Walzgerüst U2 in der Hauptwalzlinie HWL ein Stauchgerüst E1 vorgeordnet. Der erste Stich des vorgegossenen oder vorgeformten Querschnitts PR erfolgt dennoch auf dem Universal-Walzgerüst U2, wobei der Durchgang durch das vorgeordnete Duo-Stauchgerüst E1 ein Leer-Stich LS ist, ebenso der Durchgang LS durch dieses Gerüst nach dem reversierenden zweiten Universal-Stich US2 durch das Universal-Walzgerüst U2. Der reversierte nächste Stauch-Stich erfolgt dann auf dem Duo-Stauchgerüst E1; er stellt den Leit-Stich LT dar, und der dann folgende Durchgang durch das Universal-Walzgerüst U2 ist ein Leer-Stich LS. Nach Querförderung des Walzgutes aus der Hauptwalzlinie HWL in die zweite Walzlinie WLII entspricht die weitere Stichfolge der vorangegangenen Erläuterung der Anordnung nach Fig. 17.In the design of the compact rolling mill according to FIG. 18, the universal roll stand U2 is preceded by an upsetting stand E1 in the main rolling line HWL. The first pass of the pre-cast or preformed cross-section PR is nevertheless carried out on the universal roll stand U2, the passage through the upstream duo-stand E1 being an empty pass LS, as is the passage LS through this stand after the reversing second universal pass US2 thanks to the universal rolling stand U2. The reversed next upsetting stitch then takes place on the duo upsetting frame E1; it represents the master stitch LT, and the subsequent passage through the universal roll stand U2 is an empty stitch LS. After transverse conveyance of the rolling stock from the main rolling line HWL into the second rolling line WLII, the further sequence corresponds to the previous explanation of the arrangement according to FIG. 17.
