Stranqqießanlaqe zum Gießen eines Metall sträng es mit Knüppel- oder VorblockquerschnittStranqqießanlaqe for casting a metal sträng it with billet or billet cross section
Technisches GebietTechnical area
Die Erfindung betrifft eine Stranggießanlage zum Gießen eines Metallstranges mit Knüppel- oder Vorblockquerschnitt mit einer in einem Kokillentragrahmen einsetzbaren, wechselbaren und oszillierenden Kokille zum Bilden eines Metallstranges und einer an die Kokille anschließenden Strangführung zum Stützen und Führen des Metallstranges, wobei die Strangführung zwei oder mehrere Strangführungssegmente umfasst und jedes Strangführungssegmente über einen Segmenttragrahmen im Anlagentragwerk der Stranggießanlage abgestützt ist und ein in der Strangführung der Kokille unmittelbar nachfolgender erster Segmenttragrahmen mindestens zwei Strangführungssegmente abstützt.The invention relates to a continuous casting plant for casting a metal strand with billet or billet cross section with a usable in a Kokillentragrahmen, changeable and oscillating mold for forming a metal strand and adjacent to the mold strand guide for supporting and guiding the metal strand, wherein the strand guide two or more strand guide segments and each strand guide segments is supported via a segment support frame in the plant structure of the continuous casting and a immediately following in the strand guide of the mold first segment support frame at least two strand guide segments supported.
Eine wesentliche Anforderung an Stranggießanlagen besteht darin, Metallstränge mit unterschiedlichen Querschnittsabmessungen bei möglichst geringer Umrüstzeit zu gießen. Bei Knüppel- oder Vorblockgießanlagen werden je nach Querschnittsformat Rohrkokillen oder Plattenkokillen verwendet, die bei einem Gießformatwechsel ausgetauscht werden. Speziell Plattenkokillen für große Gießquerschnitte ermöglichen üblicherweise eine Breitenverstellung durch Verschieben der Schmalseitenwände und in einzelnen Fällen besteht auch die Möglichkeit, sowohl eine Breitenverstellung als auch eine Dickenverstellung vorzunehmen. Für das Gießen von Strängen bestimmter Stahlqualitäten reicht ein Formatwechsel in der Kokille oder deren Austausch jedoch nicht aus, da der noch einen flüssigen Kern aufweisende Metallstrang aus Stabilitätsgründen nach seinem Austritt aus der Kokille an allen Seiten sehr präzise gestützt und geführt werden muss. Dies bedeutet, dass auch die nachgeordneten Strangführungssegmente an das Gießformat angepasst oder gewechselt werden müssen. Weiters kann es in einzelnen Fällen zu Betriebstörungen durch einen Strangdurchbruch kommen, wobei zwischen Kokille und dem ersten, der Kokille nachgeordneten Strangführungssegment Schmelze austritt und Schäden vorzugsweise an diesem Strangführungssegment auftreten, die eine Möglichkeit eines schnellen Segmentwechsels erfordern.An essential requirement of continuous casting plants is to cast metal strands with different cross-sectional dimensions with the least possible changeover time. In billet or Vorblockgießanlagen tube molds or plate molds are used depending on the cross-sectional format, which are replaced at a Gießformatwechsel. Especially plate molds for large Gießquerschnitte usually allow width adjustment by moving the narrow side walls and in some cases it is also possible to make both a width adjustment and a thickness adjustment. For the casting of strands of certain steel grades, however, a format change in the mold or their replacement is not enough, since the metal strand still having a liquid core needs to be very precisely supported and guided on all sides for reasons of stability after it leaves the mold. This means that the downstream strand guide segments also have to be adapted or changed to the casting format. Furthermore, in individual cases, disruptions to operation may occur due to a strand break-through, whereby melt exits between the mold and the first strand guide segment arranged downstream of the mold and damage preferably occurs at this strand guide segment, which requires a possibility of a rapid segment change.
Stand der TechnikState of the art
Aus der DE 24 25 883 A1 und der EP 15 893 A1 ist bereits eine Stranggießanlage zum Gießen von Stahlsträngen mit Brammenquerschnitten bekannt, bei der einer Kokille eine Strangführung nachfolgt, mit mehreren auf Segmenttragrahmen abgestützten Strangführungssegmenten. Jeweils drei oder vier Segmente sind einem Segmenttragrahmen zugeordnet und jedes dieser Segmente kann entlang von zugeordneten Montageschienen im Wesentlichen in radialer Richtung aus der Strangführung aus- und eingebaut werden. Dieses Konzept wird speziell bei schweren Brammenstranggießanlagen angewendet und ist für Knüppel- oder Vorblockanlagen in dieser Form nicht geeignet. Eine Wechseleinrichtung zum Aus- und Einbau von Strangführungssegmenten ist aus der WO 03/076106 A2 bereits bekannt.From DE 24 25 883 A1 and EP 15 893 A1, a continuous casting plant for casting steel strands with slab cross sections is already known, in which a chill mold follows a strand guide, with a plurality of strand guide segments supported on segment support frames. Each three or four segments are assigned to a segment support frame and each of these segments can be removed and installed along associated mounting rails substantially in the radial direction of the strand guide. This concept is used especially in heavy slab casters and is not suitable for billet or bloom systems in this form. A changing device for removing and installing strand guide segments is already known from WO 03/076106 A2.
Aus der WO 97/44150 A1 ist eine Stranggießanlage zum Gießen von Metallsträngen mit Knüppel- oder Vorblockquerschnitt der gattungsbildenden Art bekannt, mit einem eine Baueinheit bildenden Maschinenkopf, der eine einfache Montage bzw. Auswechslung von Kokille, Teilen der nachfolgenden Strangführung und dem Kokillenrührer ermöglicht. Bei dieser Bauform ist das der Kokille nachfolgende Fußrollengerüst, welches eine allseitige Abstützung des gegossenen Metallstranges nach seinem Austritt aus der Kokille sicherstellen soll, in das nachfolgende zweite Strangführungssegment eingangsseitig versenkt und in diesem abgestützt. Diese Art der Abstützung erschwert die Montage und die Ausrichtung der Strangführungsrollen des Fußrollengerüstes auf die außen- und innenbogenseitigen Strangführungsrollen des zweiten Strangführungssegmentes und zur Kokille.From WO 97/44150 A1 a continuous casting plant for casting metal strands with billet or billet cross section of the generic type is known, with a unit forming a machine head, which allows easy assembly or replacement of mold, parts of the subsequent strand guide and Kokillenrührer. In this design, the mold following roller mold, which is to ensure an all-round support of the cast metal strand after its exit from the mold, sunk into the subsequent second strand guide segment on the input side and supported in this. This type of support complicates the assembly and alignment of the strand guide rollers of the caster structure on the outer and inner bow side strand guide rollers of the second strand guide segment and the mold.
Darstellung der ErfindungPresentation of the invention
Aufgabe der vorliegenden Erfindung ist es daher, die Nachteile des bekannten Standes der Technik zu vermeiden und bei einer Stranggießanlage der eingangs beschriebenen Art die Justierung der einzelnen aufeinanderfolgenden strangbildenden und strangstützenden Bauteile zueinander zu verbessern und an verschiedene Wartungsanforderungen anzupassen.The object of the present invention is therefore to avoid the disadvantages of the known prior art and in a continuous casting of the above described type to improve the adjustment of the individual successive strand-forming and strand-supporting components to each other and adapt to different maintenance requirements.
Diese Aufgabe wird bei einer Stranggießanlage der eingangs beschriebenen Art dadurch gelöst, dass das erste der Kokille unmittelbar nachfolgende Strangführungssegment lösbar am ersten Segmenttragrahmen an im Wesentlichen vertikalen Stützflächen befestigt und unabhängig von den nachfolgenden Strangführungssegmenten aus der Stranggießanlage aus- und in diese einbaubar ausgebildet ist und dass zumindest das letzte am ersten Segmenttragrahmen abgestützte Strangführungssegment ausschließlich gemeinsam mit diesem eine Baugruppe bildet und aus der Stranggießanlage aus- und in diese einbaubar ausgebildet ist. Zweckmäßig bildet das zumindest letzte am ersten Segmentrahmen abgestützte Strangführungssegment mit dem Segmentrahmen eine Baueinheit und ist als solche, vorzugsweise ausschließlich als solche, aus der Stranggießanlage aus- und in diese einbaubar ausgebildet. Für den Ein- und Ausbau mit einem Kran sind an der Baugruppe entsprechende Anschlusshaken angeordnet. Die im Wesentlichen vertikalen Stützflächen sind parallel zur Strangförderrichtung orientiert.This object is achieved in a continuous casting of the type described above in that the first of the mold directly subsequent strand guide segment releasably secured to the first segment support frame to substantially vertical support surfaces and regardless of the subsequent strand guide segments from the continuous casting and off is built into this and that at least the last supported on the first segment support frame strand guide segment forms only together with this an assembly and off the continuous casting and is designed to be installed in this. Suitably, the at least last supported on the first segment frame strand guide segment with the segment frame a unit and as such, preferably exclusively as such, from the continuous casting and trained in this trained. For the installation and removal with a crane corresponding connection hooks are arranged on the module. The substantially vertical support surfaces are oriented parallel to the strand conveying direction.
Mit dieser Lösung ist es bedarfsabhängig möglich, das erste Strangführungssegment für sich allein und ein nachfolgendes weiteres Strangführungssegment gemeinsam mit dem Segmenttragrahmen aus- und einzubauen. Damit ergibt sich die Möglichkeit, bereits außerhalb der Stranggießanlage, in einem speziellen Montagebereich, eine entsprechende Justierung der beiden ersten Segmente zueinander vorzunehmen und den Montageaufwand in der beengten Umgebung der Anlage zu minimieren. Bei einem Strangdurchbruch ergibt sich ebenfalls je nach Größe des Schadens die Möglichkeit nur das erste Segment zu wechseln oder eine weiter reichende Reparatur unabhängig vom Betrieb der Stranggießanlage durchzuführen.With this solution, it is possible depending on the need to remove and install the first strand guide segment alone and a subsequent further strand guide segment together with the segment support frame. This results in the possibility already outside the continuous casting, in a special assembly area, to make a corresponding adjustment of the two first segments to each other and to minimize the assembly effort in the cramped environment of the system. In the case of a strand breakthrough, it is also possible, depending on the size of the damage, to change only the first segment or to carry out a further-reaching repair independently of the operation of the continuous casting plant.
Eine sehr zweckmäßige Ausgestaltung der Erfindung besteht darin, dass das erste Strangführungssegment nach einem erfolgten Ausbau der Kokille und nach dem Lösen von Befestigungseinrichtungen von den im Wesentlichen vertikalen Stützflächen im Wesentlichen vertikal nach oben durch den die Kokille einnehmenden Kokillenraum ausbaubar ausgebildet ist. Der von der Kokille eingenommene freie Kokillenraum ist so bemessen, dass der Ausbau des Segmenttragrahmens mit einem mit ihm montierten oder mit ihm verbundenen Strangführungssegment mit beispielsweise einem Hallenkran durch diesen freien Kokillenraum möglich ist.A very expedient embodiment of the invention is that the first strand guide segment after a successful removal of the mold and after the release of fasteners from the substantially vertical support surfaces substantially vertically upwards by the mold accommodating mold cavity is designed expandable. The free mold space occupied by the mold is dimensioned such that the expansion of the segment support frame with a mounted or connected to it Strand guide segment with, for example, a hall crane through this free Kokillenraum is possible.
Nach einer weiteren Ausführungsform der Erfindung besteht auch die alternative Möglichkeit, das erste Strangführungssegment nach dem Lösen von Befestigungseinrichtungen gemeinsam mit der Kokille im Wesentlichen vertikal nach oben ausbaubar auszubilden. Zur Sicherung eines einfachen gemeinsamen Ausbaus von Kokille und erstem Strangführungssegment, sind beispielsweise an der Kokille und dem ersten Strangführungssegment zusammenwirkende Stützflächen vorgesehen, die bei einer Aufwärtsbewegung des ersten Strangführungssegmentes einen stützenden Kontakt mit der Kokille herstellen und die Kokille bei der Aufwärtsbewegung des ersten Strangführungssegments mitnimmt.According to a further embodiment of the invention, there is also the alternative possibility, the first strand guide segment after releasing fasteners together with the mold substantially vertically upwardly form. To ensure easy joint removal of mold and first strand guide segment, cooperating support surfaces are provided, for example, on the mold and the first strand guide segment, which produce a supportive contact with the mold during an upward movement of the first strand guide segment and entrains the mold during the upward movement of the first strand guide segment.
Nach einer bevorzugten Ausführungsform ist das erste Strangführungssegment lösbar am ersten Segmenttragrahmen befestigt und jedes weitere am ersten Segmenttragrahmen abgestützte Strangführungssegment ist fest mit dem ersten Segmenttragrahmen verbunden. Zumindest ist ein weiteres Strangführungssegment fest mit dem Segmenttragrahmen verbunden.According to a preferred embodiment, the first strand guide segment is releasably secured to the first segment support frame and each further strand guide segment supported on the first segment support frame is fixedly connected to the first segment support frame. At least another strand guide segment is firmly connected to the segment support frame.
Zur Verwirklichung einer besonders einfach durchzuführenden Einstellung der dem ersten Segmenttragrahmen zugeordneten Strangführungssegmente zueinander, bildet der erste Segmenttragrahmen eine Verlängerung des Außenbogenrahmens des dem lösbaren Strangführungssegment nachfolgendenTo achieve a particularly easy to implement adjustment of the first segment support frame associated strand guide segments to each other, the first segment support frame forms an extension of the outer arch frame of the detachable strand guide segment subsequent
Strangführungssegmentes. Die Verlängerung des Außenbogenrahmens des einen Strangführungssegmentes erstreckt sich in Richtung zur Kokille und trägt die im Wesentlichen vertikalen Stützflächen für die zwischen der Kokille und dem verbundenen Strangführungssegment angeordneten weiteren Strangführungssegmente.Strand guide segment. The extension of the outer arch frame of the one strand guide segment extends in the direction of the mold and carries the substantially vertical support surfaces for the further strand guide segments arranged between the mold and the connected strand guide segment.
Nach einer weiteren Ausführungsform der Erfindung sind alle am ersten Segmenttragrahmen abgestützten Strangführungssegmente lösbar an diesem Segmenttragrahmen befestigt. Davon unabhängig ist zumindest das in Strangförderrichtung letzte Strangführungssegment gemeinsam mit dem Segmentrahmen als Baueinheit in die Stranggießanlage ein- oder ausbaubar. Es können aber auch alle auf dem ersten Segmentrahmen befestigten Strangführungssegmente gemeinsam mit diesem als Baueinheit in die Stranggießanlage ein- und aus dieser ausgebaut werden.According to a further embodiment of the invention, all strand guide segments supported on the first segment support frame are detachably fastened to this segment support frame. Irrespective of this, at least the last strand guide segment in the strand conveying direction together with the segment frame can be installed or removed as a structural unit in the continuous casting plant. But it can also all mounted on the first segment frame Strand guide segments together with this as a unit in the continuous casting and on this expanded.
Um den gegossenen, noch einen flüssigen Kernbereich aufweisenden Metall sträng unmittelbar nach seinem Austritt aus der Kokille umfassend abzustützen, weist mindestens das erste Strangführungssegment in ihm drehbar gelagerte Strangführungsrollen auf, die an den Metall sträng sowohl in Richtung seiner Breitenerstreckung als auch in Richtung seiner Dickenerstreckung anstellbar ausgebildet sind. Diese Anstellung erfolgt vorzugsweise mit hydraulischen Stelleinrichtungen. Diese wirken auf die einer Strangseite zugeordneten Strangführungsrollen ein, die in Gruppen zusammengefasst an einem Rollenhalter drehbar abgestützt sind.In order to support the cast, still having a liquid core region metal strands immediately after its exit from the mold, at least the first strand guide segment in it rotatably mounted strand guide rollers on the metal sträng both in the direction of its width extension and in the direction of its thickness extension adjustable are formed. This employment preferably takes place with hydraulic adjusting devices. These act on the one strand side associated strand guide rollers, which are grouped together on a roll holder rotatably supported.
Nach einer vorteilhaften weiterführenden Ausgestaltung dieser zweidimensionalen Anstellmöglichkeit sind den Strangführungsrollen Spritzdüsen für eine Kühlmittelaufbringung auf die Oberfläche des Metallstranges zugeordnet, die in Richtung der Breitenerstreckung und in Richtung der Dickenerstreckung des Metallstranges auf unterschiedliche Dicken und Breiten mit einer Spritzdüsen- Verstelleinrichtung ausgerichtet sind.According to an advantageous further development of this two-dimensional Anstellmöglichkeit the strand guide rollers are assigned spray nozzles for coolant application to the surface of the metal strand, which are aligned in the direction of width extension and in the direction of the thickness extension of the metal strand to different thicknesses and widths with a Spritzdüsen- adjustment.
In Strangförderrichtung nimmt die flüssige Kernzone im Metallstrang stetig ab, wodurch der Metallstrang kontinuierlich stabiler wird und die Anforderungen an die notwendige Strangstützung abnehmen. Das letzte am ersten Segmenttragrahmen abgestützte Strangführungssegment ist mit Strangführungsrollen ausgestattet, die an den Metallstrang mindestens in Richtung seiner Dickenerstreckung anstellbar sind.In the strand conveying direction, the liquid core zone in the metal strand decreases steadily, as a result of which the metal strand becomes continuously more stable and the requirements for the necessary strand support decrease. The last strand guide segment supported on the first segment support frame is provided with strand guide rollers which are adjustable against the metal strand at least in the direction of its thickness extension.

Das erste Strangführungssegment 3d ist an im Wesentlichen vertikalen, parallel zur Strangförderrichtung ausgerichteten Stützflächen 12 des Segmentrahmens 7 abgestützt und mit Befestigungseinrichtungen 13 an diesem lösbar befestigt. Das nachfolgende Strangführungssegment 3e umfasst einen Außenbogenrahmen 14, in dem die Strangführungsrollen 6a abgestützt sind, und einen Innenbogenrahmen 15, in dem die Strangführungsrollen 6b abgestützt sind. Der Außenbogenrahmen 14 ist hierbei so ausgebildet, dass er gleichzeitig den Segmenttragrahmen 7 für das Strangführungssegment 3e bildet. Er ist damit ein fester Bestandteil des Strangführungssegmentes 3e und erstreckt sich entgegen der Strangförderrichtung bis zur Kokille 1 und bildet zusätzlich auch den Segmenttragrahmen für das erste Segment 3d.According to the first embodiment of the invention shown in Figure 1, the first of the mold 1 in strand conveying direction R immediately following segment support frame 7 carries three segments 3a, 3b, 3c, which supported on substantially vertical, or parallel to the strand transport direction aligned support surfaces 12 of the segment support frame 7 and fastened with fastening means 13 to this releasably. According to the embodiment of the invention shown in Figure 2, the first of the mold 1 in the strand conveying direction R immediately following segment support frame 7 carries two strand guide segments 3d, 3e. The first strand guide segment 3d is at substantially vertical, parallel to the strand conveying direction aligned support surfaces 12 of the segment frame 7th supported and secured with fasteners 13 to this releasably. The following strand guide segment 3e comprises an outer arch frame 14 in which the strand guide rollers 6a are supported, and an inner arc frame 15 in which the strand guide rollers 6b are supported. The outer arch frame 14 is in this case formed so that it simultaneously forms the segment support frame 7 for the strand guide segment 3e. He is thus an integral part of the strand guide segment 3e and extends against the strand conveying direction to the mold 1 and also forms the segment support frame for the first segment 3d.
Diese beiden Ausführungsformen bieten die Möglichkeit, das jeweils erste der Kokille unmittelbar nachfolgende Strangführungssegment 3a oder 3d nach einem Ausbau der Kokille unmittelbar nach oben durch den dann offenen Kokillenraum 16 aus- und einzubauen. Ein Wechsel des ersten Segmentes ist bei jedem Kokillenwechsel auf ein anderes Querschnittsformat des zu gießenden Metallstranges notwendig, da insbesondere das erste Strangführungssegment ein Korsett von Strangführungsrollen zum allseitigen Stützen des Metallstranges aufnimmt und ein allseitiges Anstellen der Strangführungsrollen an den Metallstrang üblicherweise nicht vorgesehen ist. Bei einem Strangdurchbruch besteht bei dieser Ausführungsform die Möglichkeit, ein beschädigtes erstes Strangführungssegment in einfacher Weise aus der Stranggießanlage in gleicher weise durch den Kokillenraum zu entfernen. Diese beiden Ausführungsformen bieten aber auch die Möglichkeit, das letzte mit dem Segmenttragrahmen fest oder auch lösbar verbunden Strangführungssegment gemeinsam mit dem Segmenttragrahmen durch den nach oben offenen Kokillenraum aus- und einzubauen. Damit besteht die Möglichkeit die ersten Strangführungssegmente außerhalb der Stranggießanlage in einem Montagestand einzurichten und notwendige Justierungen vorzunehmen.These two embodiments offer the possibility of immediately removing and installing the respective first strand guide segment 3a or 3d immediately after the mold has been removed, after the mold has been removed, through the then-open mold space 16. A change of the first segment is necessary for each mold change to a different cross-sectional format of the metal strand to be cast, especially since the first strand guide segment receives a corset of strand guide rollers for supporting the metal strand on all sides and an allseitiges hiring the strand guide rollers to the metal strand is usually not provided. In a strand breakthrough is in this embodiment, the possibility to remove a damaged first strand guide segment in a simple manner from the continuous casting in the same way through the mold space. But these two embodiments also offer the possibility of the last with the segment support frame fixed or releasably connected strand guide segment together with the segment support frame through the upwardly open Kokillenraum and install. This makes it possible to set up the first strand guide segments outside of the continuous casting plant in an assembly stand and to make necessary adjustments.
Der grundsätzliche Aufbau der Strangführungssegmente ermöglicht eine Anpassung an unterschiedliche Strangdicken, indem der Innenbogenrahmen 15 in Richtung zum festliegenden Außenbogenrahmen 14 mit hydraulischen Stelleinrichtungen 17 positionierbar ist.The basic structure of the strand guide segments allows adaptation to different strand thicknesses by the inner arc frame 15 can be positioned in the direction of the fixed outer arch frame 14 with hydraulic actuators 17.
Es können aber auch Strangführungssegmente 3a, 3b, 3c eingesetzt werden, die an allen Seiten eines Metallstranges mit rechteckigem oder quadratischem Strangquerschnitt Strangführungsrollen aufweisen und die sowohl in Richtung der Dickenerstreckung als auch in Richtung der Breitenerstreckung des Metallstranges auf dieses Querschnittsformat einstellbar sind. Diesen sind, gleichermaßen wie dem Strangführungssegment 3e, Kühleinrichtungen mit Spritzdüsen 18 zugeordnet, die mit einer Spritzdüsen-Verstelleinrichtung ausgerüstet sind, die einer automatisierten Formatanpassung folgt und damit eine stets zentrische Kühlmittelaufbringung auf die in ihrer Breite variablen Seitenflächen des Metallstranges sicherstellen. However, strand guide segments 3a, 3b, 3c may also be used which have strand guide rollers on all sides of a metal strand with a rectangular or square strand cross-section and which extend both in the direction of Thickness extent and in the direction of the width extension of the metal strand to this cross-sectional format are adjustable. These are, as well as the strand guide segment 3e, associated with cooling nozzles with spray nozzles 18, which are equipped with a spray nozzle adjustment, which follows an automated format adjustment and thus ensure always centric coolant application to the variable in width side surfaces of the metal strand.
