Description

StrangführungssegmentStrand guide segment
Die Erfindung betrifft ein Strangführungssegment zum Führen und Kühlen des Gußstranges einer Stranggießanlage, umfassend eine mit Traversen und Führungsrollen zwischen Seitenwänden ausgebildete Rollenbrücke, sowie eine Kühlmittelzufuhr für die Sekundärkühlung des Gußstranges und die Rahmenkühlung, wobei diese mit einer Kühlmittelverteilung und an diese anschließbare Verteilerrohre, Spritzrohre und endseitige Spritzdüse versehen sind.The invention relates to a strand guide segment for guiding and cooling the cast strand of a continuous casting installation, comprising a roller bridge formed with cross members and guide rollers between side walls, and a coolant supply for the secondary cooling of the cast strand and the frame cooling, these having a coolant distribution and distributor pipes, spray tubes and connectable thereto end spray nozzle are provided.
Bei der herkömmlichen Strangführung sind zumeist die Quertraversen zwischen den Seitenwänden eines Strangführungselementes als massive Traversen ausgebildet, und die Spritzlatten zur Strangkühlung werden von der Segmentrück- seite durch die Rollenbrücke durchgeführt.In the conventional strand guide, the cross members between the side walls of a strand guide element are usually designed as solid cross members, and the spray slats for strand cooling are carried out from the rear of the segment through the roller bridge.
Das Dokument EP 0 642 857 A2 beschreibt eine Stranggießanlage, deren Strangführungssegmente mit über die veränderlich einstellbare Breite des Stranges verteilt angeordneten, in Stranglaufrichtung gegebenenfalls in Kühlzo- nen unterteilten, an Querverteilerrohren angeschlossenen Spritzelementen, insbesondere Spritzlatten, versehen sind. Die über die minimale Strangbreite hinausgehend angeordneten, äußeren Spritzlatten sind abhängig von der jeweiligen Strangbreite zu- bzw. abschaltbar.Document EP 0 642 857 A2 describes a continuous casting installation, the strand guide segments of which are provided with spray elements, in particular spray battens, which are distributed over the variably adjustable width of the strand and are optionally divided into cooling zones and divided into cooling zones and connected to transverse distributor pipes. The outer spray battens arranged beyond the minimum strand width can be switched on or off depending on the respective strand width.
Das Dokument US-PS 4,220,192 beschreibt zum Einbau im Bereich des offenen Bodens einer vertikal ausgebildeten Kokille zum Stranggießen ein kombiniertes System von Führungsrollen und Spritzkühlung für den Strang. Die Vorrichtung besitzt einen länglichen Führungsweg, der mit Wasser geflutet wird. Der Abfluß des Wassers geschieht durch eine Anzahl von schrägen Abflüssen mit endständigen Wasserspritzdüsen, die so ausgerichtet sind, dass sie Wasser über und unter die Rollen und gegen die Oberfläche der Vorrichtung zur Kühlung versprühen.The document US Pat. No. 4,220,192 describes a combined system of guide rollers and spray cooling for the strand for installation in the region of the open bottom of a vertically formed mold for continuous casting. The device has an elongated guide path which is flooded with water. The drainage of the water occurs through a number of sloping drains with terminal water spray nozzles, which are oriented so that they contain water Spray above and below the rollers and against the surface of the cooling device.
Das Dokument EP 0 028 686 B1 beschreibt eine Versteilvorrichtung für entlang der Oberfläche eines Stranges einer Stranggießanlage verlaufende sogenannte Spritzbalken als Träger für auf die Strangoberfläche gerichtete Spritzrohre für ein Kühlmedium. Zur Änderung des Abstandes der Spritzbalken relativ zum Strang in Anpassung an wechselnde Breiten von Strangoberflächen sind die Spritzbalken zumindest zonenweise mittels eines Lenkersystems parallel zu sich selbst verstellbar. Alle auf den vier Seiten des Stranges angeordneten und sich entlang der Oberfläche des Stranges erstreckenden Spritzbalken sind von mindestens zwei Lenkhebeln getragen, derart, dass sich die Spritzbalken bei der Abstandsänderung in Richtung der Stranglängsachse bewegen. Die Lenkhebel der seitlichen Spritzbalken, die einer Strangoberfläche zugeordnet sind, deren Mitte sich bei wechselnder Breite der Strangoberfläche verlagert, sind in Schrägebenen schwenkbar. Die Schrägebenen bilden mit der jeweilig senkrecht zur zugeordneten Strangoberfläche durch die Spritzrohre verlaufenden Spritzebene einen spitzen Winkel, derart, dass mit der Abstandsänderung der Spritzbalken eine Querverschiebung der Spritzbalken samt Spritzrohre relativ zur Stranglängsachse einhergeht.Document EP 0 028 686 B1 describes an adjusting device for so-called spray bars running along the surface of a strand of a continuous casting installation as a carrier for spray tubes for a cooling medium directed onto the strand surface. In order to change the distance of the spray bars relative to the strand to adapt to changing widths of strand surfaces, the spray bars can be adjusted parallel to themselves at least in zones by means of a steering system. All the spray bars arranged on the four sides of the strand and extending along the surface of the strand are supported by at least two steering levers such that the spray bars move in the direction of the longitudinal axis of the strand when the distance changes. The steering levers of the side spray bars, which are assigned to a strand surface, the center of which shifts with changing width of the strand surface, can be pivoted in inclined planes. The inclined planes form an acute angle with the spray plane running perpendicularly to the assigned strand surface through the spray tubes, such that the change in the distance of the spray bars results in a transverse displacement of the spray bars together with the spray tubes relative to the longitudinal axis of the strand.
Das Dokument DE 30 39 443 A1 beschreibt eine Vorrichtung zur Verstellung von Düsenrohren aus der Position für eine schmale Bramme in eine einer breiteren Bramme entsprechende Position durch Verstellspindeln, wobei die Basis der Sprühfächer durch Entfernung der Sprühdüsen von der Strangoberfläche entsprechend vergrößert wird.Document DE 30 39 443 A1 describes a device for adjusting nozzle pipes from the position for a narrow slab into a position corresponding to a wider slab by adjusting spindles, the base of the spray compartments being correspondingly enlarged by removing the spray nozzles from the surface of the strand.
Das Dokument DE 197 02 718 C1 offenbart ein Verfahren und eine Vorrichtung zur Kühlmediumsteuerung in der Kühlstrecke einer Stranggießanlage, bei dem zur Erhöhung oder Reduzierung der Kühlmediummenge die auf Spritzlatten angeordneten Düsen einer Kühlzone der gesamten Kühlstrecke ein- und ausschaltbar sind. Dabei werden innerhalb einer Zone mehrere Spritzlatten selektiv ausgewählt und mindestens zu zwei Spritzgruppen zusammengefaßt und bei Unterschreiten eines festgelegten Systemdruckes für das Kühlmedium sind die einzelnen Gruppen wechselweise in einem festgelegten Zeitintervall aus- und einschaltbar.Document DE 197 02 718 C1 discloses a method and a device for controlling the cooling medium in the cooling section of a continuous casting installation, in which the nozzles of a cooling zone of the entire cooling section arranged on spray slats can be switched on and off in order to increase or reduce the quantity of cooling medium. Several spray battens become selective within one zone selected and combined into at least two spray groups and when the system pressure for the cooling medium falls below a specified value, the individual groups can be switched on and off alternately within a specified time interval.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine verbesserte, und insbesondere vereinfachte Bauart eines Strangführungssegmentes anzugeben, bei der zur Anpassung der Spritzdüsen an unterschiedliche Breiten des Gußstranges lediglich Zuleitungen für Wasseranschlüsse zu- und abzuschalten sind, und infolge Wegfalls der Wasser- Verteiler und Düsenstöcke eine sehr kompakte Bauart verwirklicht wird. Ferner soll durch kurze Spritzeinheiten eine hohe Positionsgenauigkeit der Düsen erreicht werden, eine zusätzliche Rahmenkühlung soll entfallen und eine gute Zugänglichkeit der Bauteile nach einem Durchbruch soll erzielt werden.Based on the aforementioned prior art, the invention has for its object to provide an improved, and in particular simplified design of a strand guide segment, in which only lines for water connections are to be switched on and off to adapt the spray nozzles to different widths of the cast strand, and as a result of the elimination of the water - Distributors and nozzle assemblies a very compact design is realized. Short injection units are also intended to achieve a high positional accuracy of the nozzles, additional frame cooling is to be dispensed with and good accessibility of the components after a breakthrough is to be achieved.
