Description

Die Erfindung betrifft einen Prüf- und Richtstand sowie ein Verfahren zum Messen und Richten von Gerüstabschnitten der Strangführung einer Stranggießanlage, insbesondere zum fluchtenden Einstellen zweier in Strangdurchlaufrichtung benachbarter Gerüstabschnitte, mit die Einbaulage jeweils eines gerüstabschnittes definierenden Flächen.The invention relates to a test and straightening station and to a method for measuring and straightening scaffold sections of the strand guide of a continuous casting installation, in particular for aligning two scaffold sections adjacent in the direction of strand passage, each with surfaces defining the installation position of a scaffold section.

Ein Prüf- und Richtstand dieser Art ist aus der AT-PS 360 683 bekannt. Nach Aufsetzen eines Gerüstabschnittes auf diesen Prüf- und Richtstand werden die Rollen mittels einer den Querschnittsabmessungen des zu gießenden Stranges aufweisenden Lehre eingestellt, wodurch die Mittellinie des Gerüstabschnittes genau auf ihre Ideallage gebracht wird. Dieser bekannte Prüf- und Richtstand eignet sich jedoch nur für das Einstellen vertikaler Gerüstabschnitte mit vertikalen Führungsbahnen für den Strang.A test and straightening station of this type is known from AT-PS 360 683. After a scaffold section has been placed on this test and straightening stand, the rolls are adjusted by means of a gauge having the cross-sectional dimensions of the strand to be cast, whereby the center line of the scaffold section is brought exactly to its ideal position. However, this known test and leveling station is only suitable for setting vertical scaffold sections with vertical guideways for the strand.

Die Erfindung bezweckt die Vermeidung dieses Nachteiles und stellt sich die Aufgabe, einen Prüf- und Richtstand der eingangs beschriebenen Art zu schaffen, mit dem eine schnelle Prüfung und Korrektur der Einbaulage von gekrümmten Gerüstabschnitten einer Bogenstranggießanlage möglich ist, u.zw. abseits der eigentlichen Stranggießanlage, so daß der Gießbetrieb während der Einstellarbeiten nicht behindert wird. Insbesondere soll es möglich sein, die Rollenkoordinaten der gekrümmten Strangführung festzustellen und zu korrigieren.The invention aims at avoiding this disadvantage and has as its object to create a test and straightening stand of the type described in the introduction, with which a quick test and correction of the installation position of curved scaffold sections of a continuous casting machine is possible, etc. away from the actual continuous caster, so that the casting operation is not hindered during the adjustment work. In particular, it should be possible to determine and correct the roll coordinates of the curved strand guide.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an dem Prüfstand mindestens zwei Paar im Winkel zueinander, vorzugsweise um 90° zueinander stehende Meßflächen zur Ermittlung von Rollenkoordinaten gegenüber den die Position festlegenden Stützflächen des Gerüstabschnittes vorgesehen sind.This object is achieved according to the invention in that at least two pairs of measuring surfaces, which are at an angle to one another, preferably at 90 ° to one another, are provided on the test stand for determining roller coordinates with respect to the supporting surfaces of the scaffold section which determine the position.

Gemäß einer bevorzugten Ausführungsform weist der Prüfstand horizontale und vertikale Meßflächen-auf.According to a preferred embodiment, the test stand has horizontal and vertical measuring surfaces.

Zweckmäßig weist der Prüfstand eine Mehrzahl von aufrechten Stehern mit Stützflächen für den bzw. die Gerüstabschnitt(e) auf, die entsprechend den Aufnahmen in der Stranggießanlage angeordnet sind, wobei die Meßflächen an an den Stehern befestigten, zum Gerüstabschnitt ragenden Konsolen ausgebildet sind.The test stand expediently has a plurality of upright supports with support surfaces for the scaffolding section (s), which are arranged in accordance with the receptacles in the continuous casting installation, the measuring surfaces being formed on brackets attached to the supports and projecting towards the scaffolding section.

Um auch die Einbaulage der Kokille und ihre Lage zum nachfolgenden Gerüstabschnitt vermessen bzw. einstellen zu können, sind an dem Prüfstand eine horizontale und eine vertikale Meßfläche zur Ermittlung der Einbaulage der Kokille vorgesehen, wobei diese Meßflächen so angeordnet sind, daß die der Kokille nachfolgenden Gerüstabschnitte ohne Behindern durch den Richtstand hindurchgefädelt.werden können.In order to be able to measure or adjust the installation position of the mold and its position in relation to the subsequent frame section, a horizontal and a vertical measuring surface for determining the installation position of the mold are provided on the test bench, these measuring surfaces being arranged in such a way that the frame sections following the mold can be threaded through the level without hindrance.

Eine besonders einfache Methode zum Ausrichten zweier in Strangdurchlaufrichtung benachbarter Gerüstabschnitte und anschließenden Einbau dieser Gerüstabschnitte in die Stranggießanlage unter Verwendung des erfindungsgemäßen prüf- und Richtstandes ist dadurch gekennzeichnet, daß zunächst der untere Gerüstteil in den Prüf- und Richtstand eingesetzt, unter werwendung der Meßflächen vermessen und gegebenenfalls korrigiert wird, worauf der obere Gerüstteil in den Prüf- und Richtstand eingesetzt und gegenüber dem unteren Gerüstteil mittels einer in die Strangführung einsetzbaren Zentriereinrichtung fluchtend eingestellt wird, daß sodann die beiden Gerüstteile gegeneinander fixiert, gemeinsam mit der Zentriereinrichtung aus dem Prüf- und Richtstand herausgehoben und gemeinsam in die Stranggießanlage eingesetzt werden, worauf die Zentriereinrichtung aus der Strangführung entfernt wird.A particularly simple method for aligning two scaffold sections adjacent in the strand passage direction and subsequent installation of these scaffold sections in the continuous casting installation using the test and straightening station according to the invention is characterized in that first the lower scaffold part is inserted in the test and straightening station, measured using the measuring surfaces and If necessary, it is corrected, whereupon the upper scaffold part is inserted into the test and straightening station and aligned with the lower scaffold part by means of a centering device which can be inserted into the strand guide, so that the two scaffold parts are fixed against each other, lifted out of the test and straightening station together with the centering device and are used together in the continuous caster, whereupon the centering device is removed from the strand guide.

Die Erfindung ist nachstehend anhand der Zeichnung an zwei Ausführungsbeispielen näher erläutert, wobei das erste Ausführungsbeispiel in den Fig. 1 bis 3 veranschaulicht ist. Fig. 1 zeigt eine Seitenansicht, Fig. 2 eine Draufsicht und Fig. 3 eine Seitenansicht in Richtung des Pfeiles 111 der Fig. 1 (alle Fig. sind zum Teil Schnittdarstellungen). In den Fig. 4 bis 6 ist eine zweite Ausführungsform in zu den Fig. 1 bis 3 analoger Darstellung gezeigt.The invention is explained in more detail below with reference to the drawing using two exemplary embodiments, the first exemplary embodiment being illustrated in FIGS. 1 to 3. FIG. 1 shows a side view, FIG. 2 shows a top view and FIG. 3 shows a side view in the direction of arrow 111 in FIG. 1 (all of the figures are partly sectional views). 4 to 6, a second embodiment is shown in a representation analogous to FIGS. 1 to 3.

An vier Vertikalstehern 1, die mittels Querträger 2 zu einem stabilen, am Fundament 3 abgestützten starren Käfig 4 verbunden sind, sind die Aufhängeeinrichtungen für die Biegeeinrichtung 5 (nachfolgend Biegezone genannt) einer Bogenstranggießanlage vorgesehen. Diese Aufhängeeinrichtungen werden von einem oberen Haken 6, der an einem Querträger 7 des Käfigs 4 befestigt ist und in den die Biegezone 5 mittels eines Gegenhakens 6' einhängbar ist, und einer unteren Stützfläche 8, an der sich die Biegezone 5 mittels einer Gegenstützfläche 8' abstützt, gebildet. Diese Aufhängeeinrichtungen sind in gleicher Ausgestaltung, Anordnung und in gleicher Lage zueinander vorgesehen wie die Aufhängeeinrichtungen in der Stranggießanlage selbst.On four vertical uprights 1, which are connected by means of cross members 2 to form a stable, rigid cage 4 supported on the foundation 3, the suspension devices for the bending device 5 (hereinafter referred to as the bending zone) of a continuous sheet caster are provided. These suspension devices are composed of an upper hook 6, which is fastened to a cross member 7 of the cage 4 and into which the bending zone 5 can be hung by means of a counter hook 6 ', and a lower support surface 8, on which the bending zone 5 is attached by means of a counter support surface 8' supports, formed. These suspension devices are provided in the same configuration, arrangement and in the same position with respect to one another as the suspension devices in the continuous caster itself.

An dem Käfig 4 sind an Konsolen 9 angeordnete Meßflächen 10 bis 13 starr angeordnet, die jeweils bis zur ersten und bis zur letzten Rolle 14, 15 der Biegezone 5 ragen, u.zw. sind zwei Meßflächen 10, 11 bzw. 12, 13 für jede dieser Rollen vorgesehen. Eine der beiden Meßflächen ist jeweils horizontal (Meßfläche 10 bzw. 12) und eine der Meßflächen vertikal (Meßfläche 11 bzw. 13) ausgebildet, so daß die Rollenkoordinaten dieser beiden Rollen 14, 15 genau feststellbar sind. Die Meßflächen ragen über die Rollenoberflächen 16, 17 hinaus. Durch Anlage eines Lineals läßt sich die Distanz der Rollenoberflächen 16,.17 von den Meßflächen 10 bis 13 genau vermessen.Measuring surfaces 10 to 13 arranged on brackets 9 are rigidly arranged on the cage 4 and each protrude to the first and to the last roll 14, 15 of the bending zone 5, etc. two measuring surfaces 10, 11 and 12, 13 are provided for each of these roles. One of the two measuring surfaces is in each case horizontal (measuring surface 10 or 12) and one of the measuring surfaces is vertical (measuring surface 11 or 13), so that the roller coordinates of these two rollers 14, 15 can be precisely determined. The measuring surfaces protrude beyond the roller surfaces 16, 17. The distance of the roller surfaces 16, .17 from the measuring surfaces 10 to 13 can be measured precisely by applying a ruler.

An den oberen Querträgern 2 des starren Käfigs 4, die dem in der Stranggießanlage vorgesehenen Hubtisch entsprechen, läßt sich die Kokille 18 in gleicher Weise wie auf dem Hubtisch aufsetzen, so daß auch die Lage der letzten Fußrolle 19 der Kokille zur Lage der obersten (ersten) Rolle 14 der Biegezone 5 überprüfbar ist. Anschließend wird das Maß 20 von der Festachse 21 der Kokille 18 bis zu ihrer Festseite 22 überprüft und erforderlichenfalls auf das gewünschte Soll-Maß korrigiert.On the upper cross members 2 of the rigid cage 4, which correspond to the lifting table provided in the continuous caster, the mold 18 can be placed in the same way as on the lifting table, so that the position of the last castor 19 of the mold for the position of the uppermost (first) roll 14 of the bending zone 5 can be checked. The dimension 20 from the fixed axis 21 of the mold 18 to its fixed side 22 is then checked and, if necessary, corrected to the desired target dimension.

Die Kokille und die Biegezone können anschließend getrennt voneinander ausgebaut und in die Stranggießanlage eingebaut werden.The mold and the bending zone can then be removed separately and installed in the continuous caster.

Durch die Kontrolle der Lage der ersten und letzten Rolle 14, 15 der Biegezone 5 zu den starr angeordneten Meßflächen 10 bis 13 sind die Abstände 23 bis 26 dieser Rollen 14, 15 von den Aufhängeeinrichtungen, u.zw. von den oberen Haken 6 und der unteren Stützfläche 8 feststellbar, so daß diese Maße erforderlichenfalls auf die Soll-Maße korrigiert werden können, womit sichergestellt ist, daß sich die Biege -=:e 5 nach Einhängen in die Stranggangle in zu den benachbarten Stützsegmenten genau ausgerichteter Lage befindet.By checking the position of the first and last rollers 14, 15 of the bending zone 5 to the rigidly arranged measuring surfaces 10 to 13, the distances 23 to 26 of these rollers 14, 15 from the suspension devices, etc. from the upper hook 6 and the lower support surface 8, so that these dimensions can be corrected to the target dimensions if necessary, which ensures that the bending - = : e 5 after hanging in the strand gangles in to the adjacent support segments aligned location.

Die Ausführungsform gemäß den Fig. 1 bis 3 ist insbesondere für bereits in Betrieb befindliche Stranggießanlagen besonders geeignet. Für neu gebaute Anlagen ist es zweckmäßig, die Kokille und die Biegezone gemeinsam an einem prüfstand, wie er in den Fig. 4 bis 6 dargestellt und nachfolgend beschrieben ist, zu vermessen, gegeneinander zu fixieren und gemeinsam in die Stranggießanlage einzubauen.The embodiment according to FIGS. 1 to 3 is particularly suitable in particular for continuous casting plants which are already in operation. For newly built systems, it is expedient to measure the mold and the bending zone together on a test bench, as shown in FIGS. 4 to 6 and described below, to fix them against one another and to install them together in the continuous casting system.

Die in den Fig. 4 bis 6 dargestellte Ausführungsform ist in gleicher Weise gestaltet wie der in den Fig. 1 bis 3 dargestellte Käfig 4, mit dem Unterschied, daß die Kokille auf den oberen, den Hubtisch darstellenden Querträgern mittels vier Schnellverschlüsse 27 fixierbar ist. Die Kokille 18, d.h. der die Seitenwände 28 der Kokille tragende Tragrahmen 29, stützt sich auf den oberen Querträgern 2 mittels vier an ihr befestigter Konsolen 30, von denen jeweils zwei an einer Seite der Kokille angeordnet sind, ab. Diese Konsolen weisen jeweils an ihren Enden Bohrungen 31 auf, die von an den Querträgern 2 angeordneten Bolzen 32 durchsetzt werden. Einlegestücke 33, die sich quer durch die Bolzen über die Konsolen erstrecken, dienen zum Fixieren der Kokille an dem Richtstand. Jeder der Bolzen 32 ist mittels eines Schnellverschlusses 27 mit seinem Einlegestück 33 gegen eine Konsole 30 spannbar. Dazu weist jeder Schnellverschluß zwei mit schraubenförmigen Flächen 34 aneinan.: legende Büchsen 35, 36 auf, von denen ein.; (Büchse 35) am Bolzen 32 starr montiert ist und die zwischen dieser Büchse 35 und der oberen Deckplatte 37 des Querträgers 2 liegende Büchse 36 mittels eines Druckmittelzylinders 38 schwenkbar ist. Jeweils zwei an einer Seite der Kokille angeordnete verdrehbare Büchsen sind über Hebel 39 mittels eines einzigen Druckmittelzylinders verbunden.The embodiment shown in FIGS. 4 to 6 is designed in the same way as the cage 4 shown in FIGS. 1 to 3, with the difference that the mold can be fixed by means of four quick-release fasteners 27 on the upper cross members representing the lifting table. The mold 18, i.e. the support frame 29 supporting the side walls 28 of the mold is supported on the upper cross members 2 by means of four brackets 30 attached to it, two of which are arranged on one side of the mold. These brackets each have holes 31 at their ends, through which bolts 32 arranged on the cross members 2 pass. Insert pieces 33, which extend across the bolts across the brackets, serve to fix the mold to the leveling station. Each of the bolts 32 can be clamped with its insert 33 against a bracket 30 by means of a quick release fastener 27. For this purpose, each quick-release fastener has two with helical surfaces 34: laying bushings 35, 36, one of which .; (Bush 35) is rigidly mounted on the bolt 32 and the bush 36 lying between this bush 35 and the upper cover plate 37 of the cross member 2 can be pivoted by means of a pressure medium cylinder 38. In each case two rotatable bushings arranged on one side of the mold are connected via levers 39 by means of a single pressure medium cylinder.

Die Einstellung der Kokille 18 erfolgt hier nicht von einer Festseite her, sondern die Lage der Kokille ist lediglich von der Lage der Biegezone 5 abhängig, d.h. die Kokille 18 wird genau nach der Biegezone 5 ausgerichtet. Die Einstellung der Lage der Biegezone zu ihrer Aufhängeeinrichtung erfolgt wiederum durch Vermessen der ersten und letzten Rolle der Biegezone, wie oben für die in den Fig. 1 bis 3 dargestellte Ausführungsform beschrieben. Zum Ausrichten der Kokille bzw. zum fluchtenden Einstellen zweier in Strangdurchlaufrichtung benachbarter Strangführungsabschnitte einer Stranggießanlage dient eine Zentriereinrichtung 40, wie sie in der österreichischen patentanmeldung A 1933/81 beschrieben ist. Diese Zentriereinrichtung 40 ist mittels Führungsstangen 41 und einer an diesen befestigten Querplatte 42 an der Oberseite der Kokille 18 einhängbar.The setting of the mold 18 does not take place from a fixed side here, but the position of the mold is only dependent on the position of the bending zone 5, i.e. the mold 18 is aligned exactly with the bending zone 5. The position of the bending zone in relation to its suspension device is again adjusted by measuring the first and last roll of the bending zone, as described above for the embodiment shown in FIGS. 1 to 3. A centering device 40, as described in the Austrian patent application A 1933/81, is used to align the mold or to align two strand guide sections of a continuous casting plant which are adjacent in the strand passage direction. This centering device 40 can be hung on the upper side of the mold 18 by means of guide rods 41 and a transverse plate 42 fastened thereon.

Die Zentriereinrichtung 40 selbst weist an einer Seite eine starre Zentrierplatte 43 auf, die mit den Fußrollen 19,44 der Kokille bzw. den ersten Rollen 14,45 der Biegezone 5 in Kontakt gelangen kann. Zu dieser starren Zentrierplatte ist ihr gegenüberliegend eine weitere zweigeteilt ausgebildete Zentrierplatte 46 vorgesehen, deren oberer Teil 46' mit den Fußrollen 19,44 der Kokille und deren unterer Teil 46" mit den ersten Rollen 14,45 der Biegezone 5 in Kontakt gelangen kann. Mittels als Druckmittelzylinder 47 ausgebildeter Spreizeinrichtungen sind die Zentrierplatten 45, 46 gegen die Führungsbahnen, d.h. gegen die diese Führungsbahnen bildenden Rollen preßbar. Um ein Auseinanderfallen der einander gegenüberliegenden Zentrierplatten zu verhindern, sind die Zentrierplatten mittels Gelenklaschen 48 aneinander angelenkt.The centering device 40 itself has on one side a rigid centering plate 43 which can come into contact with the castors 19, 44 of the mold or the first rolls 14, 45 of the bending zone 5. Opposite to this rigid centering plate there is provided a further centering plate 46, formed in two parts, the upper part 46 'of which can come into contact with the castors 19, 44 of the mold and the lower part 46' 'of which can come into contact with the first rolls 14, 45 of the bending zone 5 Centering plates 45, 46 can be pressed against the guideways, ie against the rollers forming these guideways, in the form of spreading means designed as pressure medium cylinders 47. To prevent the opposing centering plates from falling apart, the centering plates are articulated to one another by means of articulated brackets 48.

Die Funktion der Einrichtung ist folgende:

  • Um die Kokille 18 fluchtend gegenüber der Biegezone 5 auszurichten, wird nach vorherigem Vermessen und eventueller Korrektur der Lage der Biegezone 5 und nach Aufsetzen der Kokille 18 auf die Querträger 2 die Zentriereinrichtung 40 durch die Kokille eingefädelt, wobei die Spreizeinrichtungen 47 entspannt sind. Durch Beaufschlagen der Spreizeinrichtungen 47 - hierbei werden zunächst die Spreizeinrichtungen des unteren Teiles 46" der Zentrierplatte 46 und sodann die Spreizeinrichtungen des oberen Teiles 46' der Zentrierplatte 46 beaufschlagt - wird die Kokille 18 durch Gleiten der Konsolen 30 an den Querträgern 2 quer zur Achse 49 der Biegezone 5 in eine mit der Biegezone 5 fluchtende Lage verschoben. Sodann werden die Kokille 18 und die Biegezone 5 gemeinsam in die Stranggießanlage eingesetzt, indem die Biegezone 5 von einem Krangehänge erfaßt wird, welches in Traglaschen 50 der Biegezone, die bis an die Oberseite der Kokille 18 ragen, eingehängt wird. Hierbei gelangen an der Biegezone und an der Kokille angeordnete Stütz- bzw. - Gegenstützflächen 51,52 miteinander in Kontakt. Die Kokille 18 bleibt während dieses Vorganges durch die Zentriereinrichtung 40 in fluchtender Lage gegenüber der Biegezone 5.
The function of the facility is as follows:
  • In order to align the mold 18 in alignment with the bending zone 5, after prior measurement and possible correction of the position of the bending zone 5 and after placing the mold 18 on the cross member 2, the centering device 40 is threaded through the mold, the spreading devices 47 being relaxed. By acting on the spreading devices 47 - in this case the spreading devices of the lower part 46 "of the centering plate 46 and then the spreading devices of the upper part 46 'of the centering plate 46 are acted upon - the mold 18 is moved transversely to the axis 49 by sliding the brackets 30 on the cross members 2 the bending zone 5 into a position in alignment with the bending zone 5. Then the mold 18 and the bending zone 5 are inserted together into the continuous casting installation, in that the bending zone 5 is gripped by a crane hanger, which is carried in support tabs 50 of the bending zone, which extend up to the top the mold 18 protrude, is hooked in. In this case, support or counter-support surfaces 51, 52 arranged on the bending zone and on the mold come into contact with one another during this process, the centering device 40 keeps the mold 18 in alignment with the bending zone 5.

Nach dem gemeinsamen Einsetzen der Biegezone 5 und der Kokille 18 in die Stranggießanlage wird die Biegezone 5 am Stahlgerüst der Stranggießanlage befestigt. Hierbei kommt die Kokille mit ihren vier Traglaschen 30 mit dem nicht dargestellten Hubtisch, der in gleicher Weise gestaltet ist wie die Querträger 2 des Richtstandes 4, in Kontakt, worauf durch Betätigen der am Hubtisch ebenfalls vorgesehenen Schnellverschlüsse und nach vorherigem Einlegen von Einlegestücken in die Ausnehmungen der Bolzen dieser Schnellverschlüsse die Kokille am Hubtisch befestigt wird. Beim Aufsetzen der Kokille am Hubtisch gelangen die Stütz- und Gegenstützflächen 51, 52 der Kokille 18 bzw. Biegezone 5 außer Kontakt, so daß die Kokille 18 gegenüber der Biegezone 5 in Richtung ihrer Achse oszillieren kann. Danach werden die Spreizeinrichtungen 47 der Zentriereinrichtung 40 entspannt, und die Zentriereinrichtung 40 wird nach oben aus der Anlage ausgebaut.After the joint insertion of the bending zone 5 and the mold 18 into the continuous casting plant, the bending zone 5 becomes Steel frame of the continuous caster attached. Here, the mold with its four support lugs 30 comes into contact with the lifting table (not shown), which is designed in the same way as the crossbeams 2 of the straightening station 4, whereupon by actuating the quick-release fasteners also provided on the lifting table and after inserting inserts into the recesses the bolt of these quick-release fasteners the mold is attached to the lifting table. When the mold is placed on the lifting table, the support and counter support surfaces 51, 52 of the mold 18 or bending zone 5 come out of contact, so that the mold 18 can oscillate with respect to the bending zone 5 in the direction of its axis. Thereafter, the spreading devices 47 of the centering device 40 are relaxed, and the centering device 40 is removed upward from the system.
