Abstract
Description
Die Erfindung betrifft ein Strangführungssegment in der Strangführung einer Knüppel- oder Vorblockstranggießanlagen mit einem Segmentrahmen in dem Strangführungsrollen einander paarweise gegenüberliegend zum vierseitigen Abstützen und Führen eines gegossenen Metallstranges mit quadratischem oder rechteckigem Querschnitt zentrisch zu einer Gießmittenachse angeordnet sind.The invention relates to a strand guide segment in the strand guide of a billet or Vorblockstranggießanlagen with a segment frame in the strand guide rollers are arranged in pairs opposite each other for four-sided supporting and guiding a cast metal strand with square or rectangular cross-section centric to a Gießmittenachse.
Eine wesentliche Anforderung an Stranggießanlagen besteht darin, Metallstränge mit unterschiedlichen Querschnittsabmessungen bei möglichst geringen Umrüstzeiten zu gießen. Bei Knüppel- oder Vorblockgießanlagen werden je nach Querschnittsformat Rohrkokillen oder Plattenkokillen verwendet, die bei einem Gießformatwechsel ausgetauscht werden. Bei größeren Querschnitten und beim Gießen von Metallsträngen bestimmter Stahlqualitäten reicht ein Formatwechsel in der Kokille oder ein Austausch jedoch nicht aus, da der noch einen flüssigen Kern aufweisende Metallstrang aus Stabilitätsgründen und um speziell einen Durchbruch zu vermeiden nach seinem Austritt aus der Kokille an allen Seiten sehr präzise gestützt, geführt und gekühlt werden muss. Das bedeutet, dass auch die nachgeordneten Strangführungssegmente an das Gießformat angepasst und gewechselt werden müssen.An essential requirement of continuous casting plants is to cast metal strands with different cross-sectional dimensions with the least possible changeover times. In billet or Vorblockgießanlagen tube molds or plate molds are used depending on the cross-sectional format, which are replaced at a Gießformatwechsel. For larger cross sections and when casting metal strands of certain steel grades, a format change in the mold or an exchange is not enough, since the still a liquid core having metal strand for stability reasons and to avoid especially a breakthrough after its exit from the mold on all sides very must be precisely supported, guided and cooled. This means that the downstream strand guide segments must also be adapted to the casting format and changed.
Aus der
Beim Stranggießen von Metallsträngen mit Rechteckquerschnitt ist es unabhängig von den Querschnittsabmessungen üblich Strangführungssegmente vorzusehen, mit denen der Metallstrang an seinen Breitseiten durch aufeinanderfolgende Strangführungsrollen gestützt und geführt wird. Diese Segmente bestehen aus einem Außenbogensegmentrahmen und einem Innenbogensegmentrahmen. In einem Außenbogensegmentrahmen (Festseite) nehmen Strangführungsrollen eine feste Position ein und bestimmen den Verlauf der Strangführung. In einem Innenbogensegmentrahmen sind Strangführungsrollen abgestützt, die gemeinsam mit dem Innenbogensegmentrahmen verschiebbar sind und so auf wechselnde Strangdicken einstellbar sind. Eine zusätzliche Stützung des Metallstranges an seiner Schmalseite ist hier zumeist nicht vorgesehen.In the continuous casting of metal strands with a rectangular cross-section, it is usual to provide strand guide segments, regardless of the cross-sectional dimensions, with which the metal strand is supported and guided on its broad sides by successive strand guide rollers. These segments consist of an outer arch segment frame and an inner arc segment frame. In an outer arch segment frame (fixed side), strand guide rollers assume a fixed position and determine the course of the strand guide. In an inner arc segment frame strand guide rollers are supported, which are displaceable together with the inner arc segment frame and are adjustable to changing strand thicknesses. An additional support of the metal strand on its narrow side is not provided here in most cases.
Aus der
Aufgabe der vorliegenden Erfindung ist es daher, die Nachteile des bekannten Standes der Technik zu vermeiden und ein Strangführungssegment für eine Knüppel- und insbesondere für eine Vorblockstranggießanlage vorzuschlagen, welches in einem weiten Bereich auf verschiedene Strangquerschnitte sowohl hinsichtlich der Dickenerstreckung als auch hinsichtlich der Breitenerstreckung eines vorgesehenen Strangformates automatisch einstellbar ist.The object of the present invention is therefore to avoid the disadvantages of the known prior art and to propose a strand guide segment for a billet and in particular for a Vorblockstranggießanlage, which in a wide range to different strand cross sections both in terms of thickness and in terms of the width extension of a planned Strangformates is automatically adjustable.
In einer Weiterbildung der Erfindung ist auch die Aufgabe gestellt, eine verbesserte an verschiedene Strangquerschnitte anpassbare Kühleinrichtung vorzuschlagen.In one embodiment of the invention, the object is also to propose an improved adaptable to different strand cross-sections cooling device.
Vorzugsweise sollen mit einem derartigen Strangführungssegment Strangformate für Stränge mit einer Strangdicke zwischen 230 und 300 mm und einer Strangbreite zwischen 280 und 480 mm an vier Seiten gestützt und geführt werden können. Im Falle eines Durchbruches soll eine Öffnung des Segmentes in Richtung der Dickenerstreckung bis 350 mm und in Richtung der Breitenerstreckung bis auf 520 mm möglich sein. Diese Angaben beschreiben den bevorzugten Anwendungsbereich der Erfindung, begrenzen jedoch nicht deren Schutzbereich.Preferably, with such a strand guide segment strand formats for strands with a strand thickness between 230 and 300 mm and a strand width between 280 and 480 mm should be supported and guided on four sides. In the case of a breakthrough, the segment should be able to open up to 350 mm in the thickness direction and 520 mm in the width direction. This information describes the preferred scope of the invention, but does not limit its scope.
Diese Aufgabe wird bei einem Strangführungssegment der eingangs beschriebenen Art dadurch gelöst, dass
- im Segmentrahmen vier Rollenhalter relativ zueinander beweglich abgestützt sind, auf denen jeweils mehrere Strangführungsrollen angeordnet sind,
- dass der Segmentrahmen Führungssäulen und die Führungssäulen zueinander positionierenden Verbindungsrahmen umfasst,
- dass an den Führungssäulen zwei Tragrahmen längsverschiebbar angeordnet sind, denen jeweils zwei zueinander normal ausgerichtete Rollenhalter zugeordnet sind, wobei die beiden Tragrahmen symmetrisch zu einer Gießmittenachse verschiebbar geführt sind,
- dass ein dem Innenbogen (Losseite) eines Strangführungssegmentes zugeordneter Rollenhalter in seinem Tragrahmen in Normalrichtung auf einem den Außenbogen (Festseite) des Strangführungssegmentes zugeordneten Rollenhalter zu oder von diesem weg verschiebbar geführt ist,
- dass einer der normal zu dem den Innenbogen zugeordneten Rollenhalter ausgerichteten seitlichen Rollenhalter zusätzlich in Richtung zum gegenüberliegenden seitlichen Rollenhalter oder von diesem weg verschiebbar geführt ist.

- a roll holder assigned to the inner bow (loose side) of a strand guide segment is guided displaceably in its support frame in the normal direction on a roll holder assigned to the outer bow (fixed side) of the strand guide segment, to or away from it;
- in that one of the lateral roll holders oriented normal to the roll holder associated with the inner sheet is additionally guided displaceably in the direction of the opposite side roll holder or away from it.
Mit dieser baulichen Anordnung in einem kompakten Segmentrahmen und den darin gegebenen Verstellmöglichkeiten werden die Einstellung eines beliebigen Strangformates und auch dessen fluchtende Ausrichtung auf den Gießquerschnitt in der Kokille und die Gießmittenachse sicher gewährleistet.With this structural arrangement in a compact segmental frame and the adjustment options given therein, the setting of any desired strand format and also its alignment with the casting cross-section in the mold and the casting center axis are reliably ensured.

With this displacement device, a format adaptation in the direction of the thickness extension of the cast strand is made possible and attached to this inner-arc displacement device strand guide rollers employed on the strand.
Zusätzlich ist einer der seitlichen Rollenhalter, der normal zu dem den Innenbogen des Strangführungssegments zugeordneten Rollenhalter ausgerichtet ist, an diesem Rollenhalter verschiebbar in Richtung zum gegenüber liegenden Rollenhalter oder von diesem weg geführt. Damit wird zusätzlich zur Dickeneinstellung durch die Innenbogen-Verschiebeeinrichtung eine Breiteneinstellung des Gießformates ermöglicht und in Verbindung mit der symmetrischen Verschiebbarkeit der beiden Tragrahmen die fluchtende Einstellung auf die Position des Gießquerschnittes in der Kokille ermöglicht.In addition, one of the lateral roller holders, which is aligned normal to the roller holder associated with the inner arc of the strand guide segment, is displaceably guided on this roller holder in the direction of the opposite roller holder or away from it. Thus, in addition to the thickness adjustment by the inner-sheet displacement device allows a width adjustment of the Gießformates and in conjunction with the symmetrical displacement of the two support frame allows the alignment on the position of the Gießquerschnittes in the mold.

Jedem Tragrahmen für die Breitenverstellung ist eine Steuerkante zugeordnet, die mit einer Führungsfläche am Spritzdüsenregister zusammenwirkt, die vorzugsweise als schräge Keilfläche ausgebildet ist. Damit können die Spritzdüsen zwischen den aufeinanderfolgenden Strangführungsrollen genau mittig auf die Breitseite des gegossenen Stranges ausgerichtet werden und gleichzeitig der Abstand zur Strangoberfläche so eingestellt werden, dass ein Kantenüberspritzen des Stranges ausgeschlossen ist.Each support frame for the width adjustment is associated with a control edge, which cooperates with a guide surface on the spray nozzle register, which is preferably designed as an inclined wedge surface.

Die Kokille 1 ist als Plattenkokille ausgebildet, mit einem Formhohlraum 3 für die Aufnahme von Metallschmelze und die Ausbildung eines Metallstranges mit flüssigem Kern und einem vorbestimmten Querschnittsformat. Der Kokille 1 ist eine Gießmittenachse 4 zugeordnet, die sich aus der festgelegten Gießdicke D und Gießbreite B ergibt, und die Kokille 1 weist eine Festseite F auf, die mit der Erzeugenden der Strangführungsrollen 5 an der Festseite in den nachgeordneten Strangführungssegmenten 6, 7, 8, 9 fluchtet. In der Strangführung sind mehrere Strangführungssegmente angeordnet, in denen der gegossene Strang wie in
Sowohl an der Festseite F als auch auf der Losseite L ist jeweils ein in seiner Grundstruktur L-förmiger Tragrahmen 15a, 15b angeordnet. Jeder Tragrahmen 15a, 15b umgreift mit ringförmigen Traglaschen 16 zwei zugeordnete Führungssäulen 12a oder 12b, an denen er in Längsrichtung der Führungssäulen 12a, 12b verschiebbar abgestützt ist. Die Verschiebebewegung des Tragrahmens 15a, 15b erfolgt mit einer von einem Hydraulikzylinder gebildeten ansteuerbaren Verschiebeeinrichtung 17, die an einer der ringförmigen Traglaschen 16 des Tragrahmens 15a, 15b und an der Führungssäule 12a, 12b angelenkt ist. Die den beiden Tragrahmen 15a, 15b zugeordneten ansteuerbaren Verschiebeeinrichtungen 17 sind gegengerichtet positioniert und wirksam, so dass bei einer Gießformat-Breitenänderung eine zur Gießmittenachse 4 symmetrische, gegengerichtete Verschiebebewegung der beiden Tragrahmen 15a, 15b stattfindet. Die beiden L-förmig ausgebildeten Tragrahmen sind so angeordnet, dass sie ein die Gießmittenachse umgreifendes Geviert bilden.Both on the fixed side F and on the Losseite L each one in its basic structure L-shaped
Damit wird eine fluchtende Positionierung des eingestellten Strangformates auf das Gießformat in der Kokille möglich.This allows an aligned positioning of the set strand format on the casting format in the mold.
Die L-förmige Struktur der beiden Tragrahmen 15a, 15b begünstigt die stabile Anordnung von den gegossenen Strang stützenden und führenden Strangführungsrollen 5 an allen vier Seiten des gegossenen Stranges entlang seiner Längserstreckung über die jeweilige Segmentlänge, wie in den

Außen- und Innenbogenspritzregister 24a, 24b sind an einem in den Segmentrahmen 10 integrierten Spritzregisterrahmen 27 an Führungsstangen 28 in Richtung der Strangoberfläche des Metallstranges verschiebbar geführt und sind mit einer Spritzregister-Verschiebeeinrichtung 29 verbunden, die ihrerseits am Spritzregisterrahmen 27abgestützt ist. Jedem Tragrahmen 15a, 15b für die Breitenverstellung ist eine von einer schrägen Keilfläche 30 gebildete Steuerkante 31 zugeordnet, die mit einer Führungsfläche 32 am Spritzregisterrahmen 27 zusammenwirkt und die Spritzdüsen in eine mittige Position zur Breitseite des gegossenen Stranges bzw. zwischen den seitlichen Rollenträgern bringt. Damit ist eine spritzbreitenabhängige Positionierung der Spritzdüse in einem bestimmten Normalabstand von der zu kühlenden Strangoberfläche gewährleistet und durch die zusätzliche mittige Zentrierung werden Kantenüberspritzungen vermieden.Outer and inner
Die den seitlichen Rollenhaltern 18c, 18d zugeordneten seitlichen Spritzregister 24c, 24d sind ebenfalls im Spritzregisterrahmen 27 an Führungsstangen 28 geführt und mit einer Spritzregister-Verschiebeeinrichtung 29 gekoppelt, die ihrerseits am Spritzregisterrahmen 27 abgestützt ist. Die Führungsstangen 28 ermöglichen ein Verschieben des Spritzregisters 24c, 24d in einer Richtung parallel zur Längserstreckung der Strangführungsrollen 5 an den seitlichen Rollenhaltern 18c, 18d. Bei der dargestellten Ausführungsform ist an eine zusätzliche Anstellung in Normalrichtung auf die Strangoberfläche nicht gedacht, jedoch besteht durchaus die Möglichkeit dies analog zu den Spritzregisteranstellungen an der Los- und Festseite vorzusehen.The

Die ansteuerbaren Verschiebeeinrichtungen 17, 20 ,22 sind von ansteuerbaren Hydraulikzylindern gebildet, denen jeweils eine Wegmesseinrichtung oder ein Positionserkennungssystem 34 zugeordnet ist. Datenleitungen 35, die auch als Datenbus-System ausgebildet sein können, die auch eine Funkstrecke darstellen können, verbinden die Verschiebeeinrichtungen 17, 20, 22 oder ihnen zugeordnete Mess- und Stelleinrichtungen 34 mit einer regelnden Recheneinheit 33. Der Rechner ist in einem übergeordneten Anlagen-Regelkreis eingebunden und empfängt formatspezifizierende Vorgabedaten, die er in die Segmentsteuerung oder die Steuerung mehrerer zusammenwirkender Strangführungssegmente einbezieht. Strangführungssegmente dieser Bauart sind nicht ausschließlich zum Stützen und Führen von quadratischen oder rechteckigen Strangformaten verwendbar. Sie können gleichermaßen auch zum Stützen und Führen von Strängen mit davon abweichenden Strangformaten, wie runden, an den Eckbereichen abgerundeten, polygonalen oder "beam blank" Querschnitten angewendet werden.The
