Description

Strangführung, insbesondere für eine Stahlbrammen-Stranggießanlage Strand guide, in particular for a continuous steel slab caster

Die Erfindung betrifft eine Strangführung, insbesondere für eine Stahlbrammen- Stranggießanlage, mit einer Anzahl von Segmenten, die einen Strang an zwei einander gegenüberliegenden Seiten mit Stützelementen stützen, wobei die Stützelemente zur Führung des Strangs in eine Förderrichtung in mindestens einem unteren Rahmen und mindestens einem oberen Rahmen angeordnet sind und wobei die Rahmen an mindestens einem Mittelholm angeordnet sind.The invention relates to a strand guide, in particular for a continuous steel slab caster, with a number of segments supporting a strand on two opposite sides with support elements, wherein the support elements for guiding the strand in a conveying direction in at least one lower frame and at least one upper Frame are arranged and wherein the frames are arranged on at least one central spar.

Eine Strangführung dieser Art ist beispielsweise aus der DE 198 24 366 A1 bekannt. Die Strangführung weist eine Anzahl Stützsegmente auf, die einen Gießbogen bilden, die gegenüberliegende Reihen von Führungs- und Treibrollen haben. Die Rollen sind dabei in einem oberen und einem unteren Rahmen ge- lagert. Die Rahmen sind an einem Mittelholm (bzw. Seitenrahmen) angeordnet.A strand guide of this type is known for example from DE 198 24 366 A1. The strand guide has a number of support segments which form a pouring arc having opposed rows of guide and drive rollers. The rollers are stored in an upper and a lower frame. The frames are arranged on a central spar (or side frame).

Ähnliche Lösungen zeigen die DE 1 965 115 A1 , die DE 40 34 141 C1 , die EP 0 879 106 B1 , die EP 1 286 796 B1 und die DE 26 20 888 C2.Similar solutions are shown in DE 1 965 115 A1, DE 40 34 141 C1, EP 0 879 106 B1, EP 1 286 796 B1 and DE 26 20 888 C2.

Als Problem stellt sich bei den vorbekannten Lösungen der Aus- und Einbau eines Kreisbogensegments mit Mittelholmführung aus der bzw. in die Strangführung dar. Der Aus- und Einbau eines Segments und die damit verbundene Bewegung des Segments in Richtung zum Mittelpunkt des Gießbogens (d. h. senkrecht zur Segmentachse bzw. zur Förderichtung) können Kollisionsproble- me mit den Nachbarsegmenten hervorrufen.As a problem arises in the previously known solutions of the removal and installation of a circular arc segment with central spar guide from or in the strand guide. The removal and installation of a segment and the associated movement of the segment in the direction of the center of the casting (ie perpendicular to Segment axis or to the direction of conveyance) can cause collision problems with the neighboring segments.

Dies gilt insbesondere bei Gießmaschinen mit kleinen Gießradien. Hier können die Segmente oft nur durch Zufahren des Segmentoberrahmens auf ein Ausbauformat ausgebaut werden. Dieses Ausbauformat ist zumeist kleiner als das größte zu vergießende Format. Durch Betriebsstörungen beim Gießen des größten Formats können daher erhebliche Schwierigkeiten beim Ausbau des Segments auftreten.This applies in particular to casting machines with small casting radii. Here, the segments can often be removed only by moving the segment upper frame to a design format. This format is usually smaller than the largest format to be cast. Due to malfunction when pouring the largest format can therefore encounter considerable difficulties in the expansion of the segment.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Strangführung der eingangs genannten Art so auszugestalten, dass auch bei sehr kleinen Gießradien ein Aus- und Einbau eines Segments bzw. eines Teils desselben in verbesserter Weise möglich ist.The invention is therefore based on the object, a strand guide of the type mentioned in such a way that even with very small casting radii removal and installation of a segment or part thereof in an improved manner is possible.

Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass Mittel vorhanden sind, mit denen der mindestens eine obere und/oder der mindestens eine untere Rahmen relativ zu dem mindestens einen Mittelholm in oder entgegen der Förderrichtung verstellt werden kann.The solution of this object by the invention is characterized in that means are provided with which the at least one upper and / or the at least one lower frame can be adjusted relative to the at least one central spar in or against the conveying direction.

Dabei ist zumeist je ein Mittelholm auf jeder Seite eines Segments angeordnet.In most cases, a central spar is arranged on each side of a segment.

Die Mittel umfassen dabei bevorzugt mindestens einen Aktuator, der einen der Rahmen in Förderrichtung relativ zum Mittelholm bewegen kann. Der Aktuator kann als doppelseitig wirkende Kolben-Zylinder-Einheit ausgebildet sein. Er kann auch zwei Kolben-Zylinder-Einheiten umfassen, die am Mittelholm angeordnet sind.The means preferably comprise at least one actuator which can move one of the frames in the conveying direction relative to the central spar. The actuator may be formed as a double-acting piston-cylinder unit. It can also comprise two piston-cylinder units, which are arranged on the central spar.

Der Aktuator kann als hydraulisches Kolben-Zylinder-System, als pneumatisches Kolben-Zylinder-System oder auch als mechanisches Längenverstell- element ausgebildet sein. In letzterem Falle kann der Aktuator ein von einem Elektromotor angetriebenes Gewindespindelsystem aufweisen.The actuator can be designed as a hydraulic piston-cylinder system, as a pneumatic piston-cylinder system or as a mechanical Längenverstell- element. In the latter case, the actuator may comprise a threaded spindle system driven by an electric motor.

Die Stützelemente sind mit Vorteil als angetriebene oder nicht angetriebene Rollen ausgebildet, die im Rahmen drehbar gelagert sind. Die Segmente bilden bevorzugt einen Gießbogen. Sie können jedoch auch für den vertikal oder horizontal verlaufenden Bereich der Strangführung eingesetzt werden. Unter einem Mittelholm hier ist generell auch eine Segmentunterrahmenkon- all UIMiUi I -.u VCI 3LCI ICM, uic -.Ui v/uci i αi Ii i ici ii ui ιy αuoyouuuci ioi. ι_o

also be executed several side frame spars per segment on one side.

Mit dem erfindungsgemäßen Vorschlag wird erreicht, dass insbesondere auch bei Gießmaschinen mit kleinen Gießradien der Aus- und Einbau eines Segments wesentlich vereinfacht bzw. unter gewissen Betriebsbedingungen überhaupt erst ermöglicht werden kann. Der Oberrahmen der Nachbarsegmente kann mittels der genannten Verstellmittel zum Ausbau eines Segments so ver- fahren werden, dass das problemlose, d. h. das kollisionsfreie Herausnehmen des Segments ermöglicht wird. Nach dem Verfahren der Oberrahmen der Nachbarsegmente kann also ein Stranggießsegment entlang seiner Segmentachse, d. h. senkrecht zur Festseite, ohne Kollision an den Nachbarsegmenten vorbeigefügt werden.With the proposal according to the invention it is achieved that especially in casting machines with small casting radii of the removal and installation of a segment significantly simplified or can be made possible under certain operating conditions in the first place. The upper frame of the neighboring segments can be moved by means of the aforementioned adjusting means for the removal of a segment so that the problem-free, d. H. the collision-free removal of the segment is made possible. After the process of the upper frame of the neighboring segments so can a Stranggießsegment along its segment axis, d. H. perpendicular to the fixed side, be added past without collision on the neighboring segments.

Dies macht sich namentlich bei Bogensegmenten sehr vorteilhaft bemerkbar.This makes itself particularly advantageous in bow segments noticeable.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:In the drawing, an embodiment of the invention is shown. Show it:

Fig. 3 die drei Segmente gemäß Fig. 2 in einer Demontageposition für eines der Segmente. In Fig. 1 ist der Gießbogen einer Strangführung 1 einer Stranggießmaschine zu sehen. In bekannter Weise besteht der Gießbogen aus oinsr Anzahl Sogmcn» ten 2, die so relativ zueinander positioniert sind, dass sich ein bogenförmiger Verlauf für den (hier nicht dargestellten) Gießstrang ergibt, um ihn hinter einer Kokille von der Vertikalen in die Horizontale umzulenken. Jedes Segment 2 weist als wesentliche Bauteile zwei Rahmen 8 und 9, nämlich einen Unterrahmen 8 und einen Oberrahmen 9 auf, in die Stützelemente 6, 7 in Form von Rollen montiert sind. Die Rollen 6, 7 können dabei angetrieben oder nicht angetrieben sein, wobei ein Rahmen 8, 9 Rollen beider Arten aufweisen kann. Damit wird für den Gießstrang ein Weg in Förderrichtung F definiert.Fig. 3, the three segments of FIG. 2 in a disassembly position for one of the segments. In Fig. 1 the pouring arc of a strand guide 1 of a continuous casting machine can be seen. In known manner, consists of the casting sheet from oinsr number Sogmcn "th 2, which are positioned relative to each other such that an arc-shaped curve for the (not shown here) of the cast strand results in order to deflect it behind a mold from the vertical to the horizontal. Each segment 2 has as essential components two frames 8 and 9, namely a sub-frame 8 and an upper frame 9, are mounted in the support elements 6, 7 in the form of rollers. The rollers 6, 7 can be driven or not driven, with a frame 8, 9 can have roles of both types. This defines a path in the conveying direction F for the cast strand.

Der Aufbau eines Segments 2 gemäß einer Ausführungsform der Erfindung ergibt sich aus Fig. 2. Die einen Gießbogen bildenden Segmente sind mit 2', 2", 2'" und 2"" (in Fig. 3) bezeichnet. Bei den zum Einsatz kommenden Segmenten 2 handelt es sich um solche mit einer Mittelholmführung. Jedes Segment 2', 2", 2'" hat einen Mittelholm 10, an dessen T-förmigem Grundteil ein (in Fig. 2 und Fig. 3 nicht näher dargestellter) Unterrahmen 8 fest angeordnet ist, der Stützelemente in Form von Rollen 6 trägt, die die eine Seite 4 des Strangs 3 abstützen. Ferner ist ein Oberrahmen 9 am Mittelholm 10 angeordnet, der gleichermaßen Stützelemente in Form von Rollen 7 trägt, die die Seite 5 des Strangs 3 führen.The structure of a segment 2 according to an embodiment of the invention is shown in FIG. 2. The segments forming a casting arc are designated 2 ', 2 ", 2'" and 2 "" (in FIG. 3). The segments 2 used are those with a central spar guide. Each segment 2 ', 2 ", 2'" has a central spar 10, on whose T-shaped base part (not shown in detail in FIGS. 2 and 3) subframe 8 is fixed, which carries supporting elements in the form of rollers 6 , which support one side 4 of the strand 3. Furthermore, an upper frame 9 is arranged on the central spar 10, which likewise carries supporting elements in the form of rollers 7, which guide the side 5 of the strand 3.

Die Einstellung der Rollen 6 und 7 relativ zueinander, d. h. die Einstellung des für den Strang 3 verbleibenden Spalts zwischen den Rollen 6, 7, erfolgt durch Einstellzylinder 17, wie es als solches bekannt sind.The adjustment of the rollers 6 and 7 relative to each other, d. H. the adjustment of the remaining gap for the strand 3 between the rollers 6, 7, carried by adjusting cylinder 17, as it is known as such.

Wesentlich ist, dass die Oberrahmen 9 am Mittelholm 10 - abgesehen von der in jedem Fall vorgesehenen Einstellung des Walzspalts zwischen den Rollen 5, 6 durch die Einstellzylinder 17 - nicht fest angeordnet sind, sondern dass sie über Mittel 11 zum Verstellen so am Mittelholm 10 angeordnet sind, dass eine Verschiebung des Oberrahmens 9 relativ zum Mittelholm 10 in Förderrichtung F möglich ist. Die Mittel 11 weisen einen Aktuator 12 auf, der vorliegend aus zwei Kolben-Zylinder-Einheiten besteht, mit denen der Oberrahmen 9 relativ zum iviiLLdi IUM 1 1 ι u i ui uci i IUI ILUi IU, i uud αuυi i d nycyσi ι uui oυiuυi ι vci oυi ι werden kann. Hierzu ist eine geeignete Gleitführung vorgesehen, die eine stabile Verschiebebewegung des Oberrahmens 9 relativ zum Mittelholm 10 mittels des Aktuators 12 erlaubt.It is essential that the upper frame 9 on the central spar 10 - apart from the provided in each case setting of the roll gap between the rollers 5, 6 by the adjusting cylinder 17 - are not fixed, but that they are arranged on means 11 for adjusting so on the central spar 10 are that a displacement of the upper frame 9 relative to the central spar 10 in the conveying direction F is possible. The means 11 have an actuator 12, in the present case of two Piston-cylinder units consists, with which the upper frame 9 relative to iviiLLdi IUM 1 1 ι ui ui uci i IUI ILUi IU, u uud uy id nycyσi ι uui oυiuυi ι vci oυi ι can be. For this purpose, a suitable sliding guide is provided, which allows a stable displacement movement of the upper frame 9 relative to the central spar 10 by means of the actuator 12.

Der damit erzielbare Effekt ergibt sich aus der Synopse der Figuren 2 und 3: Soll ein Segment 2, und zwar im Beispiel der Figur 2 bzw. 3 das rechte Segment 2'", ausgebaut werden, ist hierfür ein gewisser Montageraum erforderlich, um das Segment in Richtung zum Mittelpunkt des Gießbogens herausheben zu können.The effect achievable therefrom results from the synopsis of FIGS. 2 and 3: If a segment 2, in the example of FIGS. 2 and 3, the right segment 2 '", is to be removed, a certain mounting space is required for this purpose to lift out in the direction of the center of the pouring arc.

In Fig. 2 ist eine mögliche Arbeitsposition der Segmente 2 dargestellt. Ferner ist hier die Ausbauraumgrenze 13 mit einer strichpunktierten Linie eingetragen. Würde das rechte Segment 2'" in Richtung Mittelpunkt des Gießbogens her- ausbewegt, würde es an der mit 14 markierten Stelle mit dem Oberrahmen des mittleren Segments 2" kollidieren.2, a possible working position of the segments 2 is shown. Furthermore, here the expansion space boundary 13 is entered with a dot-dash line. If the right segment 2 '"were moved in the direction of the center of the casting arc, it would collide with the top frame of the middle segment 2" at the location marked 14.

Um dies zu verhindern, wird wie in Fig. 3 dargestellt vorgegangen.To prevent this, the procedure is as shown in Fig. 3.

Der Oberrahmen 9 des mittleren dargestellten Segments 2" (genauso wie der Oberrahmen des nur noch grob angedeuteten, sich in Fig. 3 rechts anschließenden Segments 2"") wird relativ zum Mittelholm 10 durch den Aktuator 12 entgegen der Förderrichtung F verschoben. Demgemäß bewegt sich die Mittenachse 15 des Oberrahmens 9 von der Mittenachse 18 des Mittelholms 10 weg. In Fig. 3 ist zu sehen, dass der Oberrahmen 9 von dem Mittelholm 10 um den Verschiebeweg x durch den Aktuator 12 verschoben wurde. Demgemäß ist hierdurch ein Montagespiel 16 im Bereich der Ausbauraumgrenze 13 entstanden. Dasselbe geschieht am Oberrahmen des sich rechts an das auszubauende Segment 2'" anschließenden Segments 2"", das in Förderrichtung F ver- schoben wird, so dass auch ein entsprechendes Montagespiel im Bereich der anderen Ausbauraumgrenze 19 vorliegt. Das in Fig. 3 rechts dargestellte Segment 2'" kann nun koüisionεfrei aus der Strangführung in Richtung zum Mittelpunkt des Gießbogens herausgehoben werden.The upper frame 9 of the middle illustrated segment 2 "(as well as the upper frame of the only roughly indicated, in Fig. 3 right subsequent segment 2"") is moved relative to the central spar 10 by the actuator 12 against the conveying direction F. Accordingly, moves the central axis 15 of the upper frame 9 away from the center axis 18 of the central spar 10. In Fig. 3 it can be seen that the upper frame 9 has been displaced from the central spar 10 by the displacement x by the actuator 12. Thus, a mounting clearance 16 is in the range The same happens on the upper frame of the segment 2 "following the upper frame of the segment 2" which is to be removed, which is displaced in the conveying direction F, so that a corresponding mounting clearance is also present in the region of the other expansion space boundary 19. The segment 2 '"shown on the right in FIG. 3 can now be lifted out of the strand guide in the direction of the center of the casting arc without any risk of coagulation.

Für die Verstellung des Aktuators 12 können beliebige Systeme eingesetzt werden. Gemäß einer Ausgestaltung der Erfindung ist ein hydraulisches Kolben- Zylinder-System vorgesehen. Es ist aber auch genauso möglich, ein elektrisches System einzusetzen, d. h. beispielsweise eine Gewindespindel oder ein anderes mechanisches Getriebe und ein Elektromotor zu deren bzw. dessen Antrieb. Ebenfalls ist ein pneumatisches System möglich.For the adjustment of the actuator 12, any systems can be used. According to one embodiment of the invention, a hydraulic piston-cylinder system is provided. But it is also possible to use an electrical system, d. H. For example, a threaded spindle or other mechanical transmission and an electric motor to the or its drive. Also a pneumatic system is possible.

Die Erfindung sieht also insbesondere ein Verschieben der Oberrahmen der Segmente mittels geeigneter Stellelemente senkrecht zur Segmentachse (parallel zur Festseite) vor, um den für die Demontage bzw. Montage eines Seg- ments benötigten Montageraum zu schaffen.The invention thus provides, in particular, a displacement of the upper frames of the segments by means of suitable adjusting elements perpendicular to the segment axis (parallel to the fixed side), in order to provide the installation space required for the disassembly or assembly of a segment.

Die im Ausführungsbeispiel vorgesehene Ausgestaltung des Aktuators 12 durch zwei Betätigungszylinder erlaubt wahlweise die Verschiebung des Oberrahmens 9 in der Figur nach rechts oder links, je nachdem, welches Segment aus- bzw. einzubauen ist.The embodiment of the actuator 12 provided in the exemplary embodiment by two actuating cylinders optionally allows the displacement of the upper frame 9 in the figure to the right or left, depending on which segment is to be removed or installed.

In Fig. 2 ist eine mögliche Arbeitsposition der Vorrichtung illustriert. Es sei angemerkt, dass eine Verstellung eines oberen Rahmens 9 auch als mögliche variable Einstellung im Gießbetrieb verwendet werden kann, beispielsweise um eine Verschiebung von Richtpunkten vornehmen zu können.In Fig. 2, a possible working position of the device is illustrated. It should be noted that an adjustment of an upper frame 9 can also be used as a possible variable setting in the casting operation, for example in order to be able to make a shift of directional points.
