Definitions
- the invention relates to a strand guide segment in a slab or Dünnbrammenstrangg imaginestrom according to the preamble of claim 1.
- Amaschinerollengerüst which is suitable for slab and Dünnbrammenstrangg intelligent fabric is from the AT-B 332 986 already known.
- the strand guide rollers are supported with their roller pins in bearing chocks, which have vertical guides which cooperate with corresponding counter-guides onmaschinerollegerüstrahmen and attack on which pressure medium cylinder as adjusting. Since the two bearing chocks are loaded independently by the pressure cylinder, there is a risk of uneven loading of the strand and the tilting of the strand guide roller in the guides.
- Strand guides are known in which a plurality of successively arranged roller sets are summarized to form a structural unit (segment), which is formed by an outer arc segment frame and an inner arc segment frame.
- the inner arc segment frame is formed with all its strand guide rollers in its distance relative to the outer arc segment frame displaced.
- driver rollers are carried out in the embodiment according to the AT-B 335 650 by two inclined to each other employed pressure cylinder, which engage at the edge regions of the driver rollers supporting cross member which is coupled via a parallel link system with the roller carriers of the other strand guide rollers on the inner arc segment frame.
- This solution is mechanically complex and costly.
- the object of the invention is therefore to avoid these disadvantages and to propose a strand guide segment, which enables the symmetrical application of a contact pressure on the cast strand with constructively little effort and reliably ensures the alignment of co-operating strand guide rolls. Furthermore, a reduction of investment and operating costs is sought.
- the stated object is achieved according to the invention in that exclusively an adjusting device acting centrally on the displaceable roller carrier and on the inner curved segment frame is arranged, and guides on the displaceable roller carrier are engaged with counter guides on the inner curved segment frame.
- the adjustment is fixed with swivel joints on the roller carrier and the inner arc segment frame. This effect is further enhanced if the connection line of the two pivot joints of the adjusting device, which corresponds to the line of action of the force application, is normal to the center axis of the displaceable strand guide rollers. Likewise, this effect is achieved when the connecting line of the two pivot joints intersects the central axes of a roller pair forming strand guide rollers.
- the adjusting device is preferably formed by a controllable hydraulic cylinder.
- An advantageous embodiment of the invention is that the guides on the roller carrier and the counter guides on the inner arc segment frame form contact surfaces, which are oriented parallel to the connecting line of the two pivot joints of the adjustment. This ensures that the line of action of the force application is consistent with the direction of movement of the roller carrier. By a corresponding length of the guides and counter guides tilting of the roller carrier in the guide element frame is avoided.
- FIG. 1 shows an axonometric representation of a strand guide segment with an integrated pair of driving rollers
- FIG. 2 shows in a partial section of FIG. 1 the displaceable roller carrier arranged in the inner arc segment frame.
- a cast strand with a still liquid core and a thin strand shell is formed continuously in an oscillating cooled continuous casting mold.
- downstream strand guide with several meters radius of curvature of the casting strand is deflected under constant cooling of substantially vertical direction in the horizontal direction and there.
- a plurality of strand guide rollers which are arranged in two rows, form a transport channel for the cast strand, in which it is supported and guided.
- Some of the strand guide rollers are designed as driver rollers and provided with a motor drive to ensure a controlled conveying speed for the casting strand and at the start of casting for the starter strand.
- Such a continuous casting plant is for example from the DE-A 197 45 056 known.
- the strand guide is composed of individual strand guide segments, as one is shown schematically in Fig. 1 in axonometric representation. It is formed by an outer arch segment frame 1 and an inner arch segment frame 2 which are interconnected by four hydraulically actuable bracing devices 3a, 3b, 3c, 3d arranged in the corner regions of the segment frame, which allow a predetermined positioning of the inner arch segment frame 2 to the outer arch segment frame 1. This can be done in succession arranged roller carrier 4 mounted strand guide rollers 5 can be adjusted to the degree of strand thickness or casting start on the thickness of the Anfahrstranges. Each strand guide roller 5 is formed as a continuous, multi-bearing roller or a plurality of aligned rollers.
- roller carriers 4 are firmly attached to the inner arch 2 or outer arch segment frame 1. However, the roller carriers 4 may also be formed only by the bearing housings 6, which are attached directly to the respective segment frame.
- Fig. 2 shows in a partial section of Fig. 1 arranged in an inner sheet segment frame 2 roller carrier 7, the bearing 8 carries bearings that receive a multi-mounted, connected to a drive 9a strand guide roller 5a rotatably.
- a similar driven strand guide roller 5b is arranged opposite in the outer arch segment frame 1 and in Fig. 1 by the drive 9b, which is opposite to the drive 9a, indicated.
- the driven strand guide roller 5 b is supported in stationary roller carriers 4 in the same way as the adjacent strand guide rollers 5 fastened in the outer arch segment frame 1.
- the provided for the opposite driven strand guide roller 5a displaceable roller carrier 7 is connected on the one hand via a pivot joint 11 with a controllable pressure cylinder 10 and supported on the other hand via a pivot joint 12 on the inner arc segment frame 2.
- the two pivot joints 11, 12 define a connecting line 13, which corresponds to the line of action of the force application on the cast strand and coincides in Fig. 2 with the central axis of the pressure medium cylinder 10.
- this connection line 13 intersects the central axis 14 of the driven strand guide roller 5a in the middle of its longitudinal extent. This ensures a uniform pressure distribution on the cast strand along the contact line of strand guide roll and cast strand.
- Guides 15a, 16a are fastened on both sides to the displaceable roller carrier 7 in parallel with the connecting lines 13, which interact with corresponding counter-guides 15b, 16b on the inner arc segment frame 2.
- the guides 15a are arranged on the broad sides of the roller carrier 7, approximately at a distance of half a strand guide roller 5a of its side edges.
- the guides 16a bear against the end faces of the roller carrier.
- the guides 15a and counter guides 15b stabilize the Roller carrier 7 in the casting direction G, the guides 16a and counter guides 16b in the transverse direction thereto.
- the driven strand guide rollers 5a, 5b, the pressure cylinder 10 and the associated guides 15a, 16a formed strand guide element can also without the adjacent stationary strand guide rollers 5 may be arranged as a narrow self-contained strand guide element in the strand guide a continuous casting.
- the outer arc segment frame 1 and the inner arc segment frame 2 are thereby reduced to a guide element frame 17 for the displaceable roller carrier 7 with pressure medium cylinder 10 and the associated guides 15a, 15b, 16a, 16b.

Abstract
Description
Die Erfindung betrifft ein Strangführungssegment in einer Brammen- oder Dünnbrammenstranggießanlage gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a strand guide segment in a slab or Dünnbrammenstranggießanlage according to the preamble of claim 1.
In einer Stranggießanlage sind im Bereich der Strangführung zwischen Kokille und dem horizontal angeordneten Auslaufrollgang in Abständen voneinander an den Gießstrang und bei Gießbeginn an den Anfahrstrang anstellbare und antreibbare Strangführungsrollen angeordnet. Durch die von diesen Strangführungsrollen aufgebrachten Anpresskräfte wird der kontrollierte Transport des Gießstranges bzw. des Anfahrstranges durch die Stranggießanlage mit einer vorbestimmten Fördergeschwindigkeit sichergestellt.In a continuous casting in the strand guide between mold and the horizontally arranged outfeed roller table at intervals from each other to the casting strand and at casting start to the Anfahrstrang engageable and drivable strand guide rollers are arranged. By the contact forces applied by these strand guide rollers, the controlled transport of the cast strand or the Anfahrstranges is ensured by the continuous casting at a predetermined conveying speed.
Bei Knüppelstranggießanlagen zum Gießen von Strängen mit nur geringer Querschnittsfläche bis etwa 200mm x 200mm ist es bekannt, einige Treibwalzengerüste in der Strangführung im Abstand voneinander anzuordnen, bei denen die anstellbare und antreibbare Strangführungsrolle des zusammenwirkenden Rollenpaares an einem Schwenkarm gelagert ist, der einerseits mit einer Anstelleinrichtung zum Anpressen der Strangführungsrolle an den Strang gekoppelt und andererseits im Treibwalzengerüstrahmen schwenkbar abgestützt ist (

Aufgabe der Erfindung ist es daher diese Nachteile zu vermeiden und ein Strangführungssegment vorzuschlagen, welches mit konstruktiv geringem Aufwand die symmetrische Aufbringung eines Anpressdruckes auf den Gießstrang ermöglicht und das Fluchten zusammenwirkender Strangführungsrollen sicher gewährleistet. Weiters wird eine Reduktion der Investitions- und Betriebskosten angestrebt.The object of the invention is therefore to avoid these disadvantages and to propose a strand guide segment, which enables the symmetrical application of a contact pressure on the cast strand with constructively little effort and reliably ensures the alignment of co-operating strand guide rolls. Furthermore, a reduction of investment and operating costs is sought.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass ausschließlich eine zentrisch am verlagerbaren Rollenträger und am Innenbogensegmentrahmen angreifende Verstelleinrichtung angeordnet ist und Führungen am verlagerbaren Rollenträger mit Gegenführungen am Innenbogensegmentrahmen in Eingriff sind.The stated object is achieved according to the invention in that exclusively an adjusting device acting centrally on the displaceable roller carrier and on the inner curved segment frame is arranged, and guides on the displaceable roller carrier are engaged with counter guides on the inner curved segment frame.
Um die symmetrische Verteilung des Anpressdruckes entlang der Berührungslinie von Gießstrang und angestellter Strangführungsrolle zu gewährleisten, ist die Verstelleinrichtung mit Schwenkgelenken am Rollenträger und am Innenbogensegmentrahmen befestigt. Dieser Effekt wird weiter verstärkt, wenn die Verbindungslinie der beiden Schwenkgelenke der Verstelleinrichtung, die der Wirkungslinie der Kraftaufbringung entspricht, normal auf der Mittenachse der verlagerbaren Strangführungsrollen steht. Gleichermaßen wird dieser Effekt erreicht, wenn die Verbindungslinie der beiden Schwenkgelenke die Mittelachsen der ein Rollenpaar bildenden Strangführungsrollen schneidet. Die Verstelleinrichtung wird vorzugsweise von einem regelbaren Hydraulikzylinder gebildet.In order to ensure the symmetrical distribution of the contact pressure along the contact line of cast strand and employee strand guide roller, the adjustment is fixed with swivel joints on the roller carrier and the inner arc segment frame. This effect is further enhanced if the connection line of the two pivot joints of the adjusting device, which corresponds to the line of action of the force application, is normal to the center axis of the displaceable strand guide rollers. Likewise, this effect is achieved when the connecting line of the two pivot joints intersects the central axes of a roller pair forming strand guide rollers. The adjusting device is preferably formed by a controllable hydraulic cylinder.
Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, dass die Führungen am Rollenträger und die Gegenführungen am Innenbogensegmentrahmen Berührungsflächen bilden, die parallel zur Verbindungslinie der beiden Schwenkgelenke der Verstelleinrichtung orientiert sind. Damit wird erreicht, dass die Wirkungslinie der Kraftaufbringung gesichert mit der Bewegungsrichtung des Rollenträgers übereinstimmt. Durch eine entsprechende Länge der Führungen und Gegenführungen wird ein Verkanten des Rollenträgers im Führungselementrahmen vermieden.An advantageous embodiment of the invention is that the guides on the roller carrier and the counter guides on the inner arc segment frame form contact surfaces, which are oriented parallel to the connecting line of the two pivot joints of the adjustment. This ensures that the line of action of the force application is consistent with the direction of movement of the roller carrier. By a corresponding length of the guides and counter guides tilting of the roller carrier in the guide element frame is avoided.
Die Erfindung ist nachfolgend anhand eines nicht einschränkenden Ausführungsbeispieles näher erläutert, wobei Fig. 1 eine axonometrische Darstellung eines Strangführungssegmentes mit einem integrierten Treibrollenpaar zeigt und Fig. 2 in einem Teilschnitt der Fig. 1 den im Innenbogensegmentrahmen angeordneten verlagerbaren Rollenträger.The invention is explained in more detail below with reference to a non-limiting exemplary embodiment, wherein FIG. 1 shows an axonometric representation of a strand guide segment with an integrated pair of driving rollers and FIG. 2 shows in a partial section of FIG. 1 the displaceable roller carrier arranged in the inner arc segment frame.
In einer Stranggießanlage zur Herstellung von Strängen im Brammenformat wird in einer oszillierenden gekühlten Stranggießkokille kontinuierlich ein Gießstrang mit noch flüssigem Kern und einer dünnen Strangschale gebildet. In einer der Stranggießkokille in Gießrichtung nachgeordneten Strangführung mit mehreren Metern Krümmungsradius wird der Gießstrang unter ständiger Kühlung von im Wesentlichen vertikalen Richtung in die Horizontale umgelenkt und dort gerade gerichtet. Eine Vielzahl von Strangführungsrollen, die in zwei Reihen angeordnet sind, bilden einen Transportkanal für den Gießstrang, in dem er gestützt und geführt wird. Einige der Strangführungsrollen sind als Treiberrollen ausgebildet und mit einem motorischen Antrieb versehen, um eine kontrollierte Fördergeschwindigkeit für den Gießstrang und bei Gießbeginn für den Anfahrstrang zu gewährleisten. Eine derartige Stranggießanlage ist beispielsweise aus der
Die Strangführung ist aus einzelnen Strangführungssegmenten zusammengesetzt, wie eines in Fig. 1 in axonometrischer Darstellung schematisch dargestellt ist. Es ist von je einem Außenbogensegmentrahmen 1 und einem Innenbogensegmentrahmen 2 gebildet, welche durch vier in den Eckbereichen der Segmentrahmen angeordnete, hydraulisch betätigbare Verspanneinrichtungen 3a, 3b, 3c, 3d miteinander verbunden sind, die eine vorgegebene Positionierung des Innenbogensegmentrahmen 2 zum Außenbogensegmentrahmen 1 zulassen. Damit können die in hintereinander angeordneten Rollenträger 4 gelagerten Strangführungsrollen 5 auf das Maß der Strangdicke oder bei Gießbeginn auf die Dicke des Anfahrstranges eingestellt werden. Jede Strangführungsrolle 5 ist als durchgehende, mehrfach gelagerte Rolle oder von mehreren fluchtenden Rollen gebildet. Einander gegenüberliegende Strangführungsrollen 5 bilden ein zusammenwirkendes Rollenpaar. Die Rollenträger 4 sind fest am Innenbogen- 2 bzw. Außenbogensegmentrahmen 1 befestigt. Die Rollenträger 4 können jedoch auch nur von den Lagergehäusen 6 gebildet sein, die direkt am jeweiligen Segmentrahmen befestigt sind.The strand guide is composed of individual strand guide segments, as one is shown schematically in Fig. 1 in axonometric representation. It is formed by an outer arch segment frame 1 and an inner
Fig. 2 zeigt in einem Teilschnitt der Fig. 1 einen im Innenbogensegmentrahmen 2 angeordneten Rollenträger 7, der Lagerstellen 8 trägt, die eine mehrfach gelagerte, mit einem Antrieb 9a verbundene Strangführungsrolle 5a drehbeweglich aufnehmen. Eine gleichartige angetriebene Strangführungsrolle 5b ist im Außenbogensegmentrahmen 1 gegenüberliegend angeordnet und in Fig. 1 durch den Antrieb 9b, der dem Antrieb 9a gegenüberliegt, angedeutet. Die angetriebene Strangführungsrolle 5b ist gleichermaßen wie die benachbarten im Außenbogensegmentrahmen 1 befestigten Strangführungsrollen 5 in stationären Rollenträgern 4 abgestützt. Der für die gegenüberliegende angetriebene Strangführungsrolle 5a vorgesehene verlagerbare Rollenträger 7 ist einerseits über ein Schwenkgelenk 11 mit einem ansteuerbaren Druckmittelzylinder 10 verbunden und andererseits über ein Schwenkgelenk 12 am Innenbogensegmentrahmen 2 abgestützt. Die beiden Schwenkgelenke 11, 12 bestimmen eine Verbindungslinie 13, die der Wirkungslinie der Kraftaufbringung auf dem Gießstrang entspricht und in Fig. 2 mit der Mittelachse des Druckmittelzylinders 10 zusammenfällt. Damit schneidet diese Verbindungslinie 13 die Mittelachse 14 der angetriebenen Strangführungsrolle 5a in der Mitte ihrer Längserstreckung. Damit ist eine gleichmäßige Druckverteilung auf den Gießstrang entlang der Berührungslinie von Strangführungsrolle und Gießstrang gewährleistet.Fig. 2 shows in a partial section of Fig. 1 arranged in an inner
Parallel zu den Verbindungslinien 13 sind Führungen 15a, 16a beidseitig am verlagerbaren Rollenträger 7 befestigt, die mit entsprechenden Gegenführungen 15b, 16b am Innenbogensegmentrahmen 2 zusammenwirken. Die Führungen 15a sind an den Breitseiten des Rollenträgers 7, etwa im Abstand einer halben Strangführungsrolle 5a von seinen Seitenrändern angeordnet. Die Führungen 16a liegen an den Stirnseiten des Rollenträgers an. Die Führungen 15a und Gegenführungen 15b stabilisieren den Rollenträger 7 in Gießrichtung G, die Führungen 16a und Gegenführungen 16b in Querrichtung dazu.
Das anhand der Fig. 1 und 2 dargestellte, in ein Strangführungssegment integrierte, von einem verlagerbaren Rollenträger 7, einem stationären Rollenträger 4, den angetriebenen Strangführungsrollen 5a, 5b, dem Druckmittelzylinder 10 und den zugeordneten Führungen 15a, 16a gebildete Strangführungselement kann auch ohne die benachbarten stationären Strangführungsrollen 5 als schmal gebautes eigenständiges Strangführungselement in der Strangführung einer Stranggießanlage angeordnet sein. Der Außenbogensegmentrahmen 1 und der Innenbogensegmentrahmen 2 reduzieren sich dadurch auf einen Führungselementrahmen 17 für den verlagerbaren Rollenträger 7 mit Druckmittelzylinder 10 und den zugeordneten Führungen 15a, 15b, 16a, 16b.The illustrated with reference to FIGS. 1 and 2, integrated in a strand guide segment, of a movable roller carrier 7, a stationary roller carrier 4, the driven strand guide rollers 5a, 5b, the
