Definitions

  • Continuous casting plants are known, on which, alternatively, beam pre-profiles and blooms are cast. It is customary to provide a strand guide with rollers for guiding the web of the carrier pre-profiles or a strand guide with rollers for guiding the bloom. Depending on the type of strand to be cast, the strand guides are removed and installed or replaced. This is economically disadvantageous due to the necessary exchange work.
  • the aim of the invention is to design a strand guide in such a way that both types of strand can be cast on a continuous casting installation without removing these strand guides. This should increase the economy of the continuous caster with increased productivity and lower costs.
  • a carrier pre-profile 1 is guided by rollers 2 on the web and by rollers 4 on the flange sides.
  • the rollers 2 are mounted on one side of the carrier, on an inner carrier 5 and on the outer carrier 6, and the rollers 4 are supported on side carriers 3.
  • the carrier 3 are slidably held on a frame 9 by adjusting screws 8.
  • the carriers 5 and 6 are rotatable about axes 11. As can be seen from FIG. 2, the rotation takes place via a drive 10.
  • the bearings for the axes 11 are designated by 12.
  • Brackets 14 are provided on the frame 9 for the inner and outer supports 5 and 6. With 15 fixing screws are designated, which press the brackets 14 on the carrier 5 and 6 and prevent an unwanted rotation of the same and position them.
  • a pre-block format 16 is to be cast, the set screws 8 are loosened and the flange rollers 4 are shifted in the direction of arrow 17. Then the screws 15 are loosened in order to loosen the brackets 14 of the outer carrier 6. The axis 11 is then rotated 180 in the direction of the arrow 18 by the drive 10, as a result of which the positions of the roller 2 and the roller 7 are interchanged. Manual rotation is also possible. The inner support 5 is subsequently rotated in the same way. After the rotation of both supports 5 and 6, they are received by the brackets 14 and secured with the screws 15.

Description

Es sind Stranggiessanlagen bekannt, auf denen alternativ Träger-Vorprofile und Vorblöcke gegossen werden. Dabei ist es üblich, eine Strangführung mit Rollen zur Führung des Steges der Träger-Vorprofile oder eine Strangführung mit Rollen zur Führung des Vorblockes vorzusehen. Je nach Art des zu giessenden Stranges werden die Strangführungen aus- und eingebaut bzw. gewechselt. Dies ist, bedingt durch die notwendige Wechselarbeit, wirtschaftlich nachteilig.Continuous casting plants are known, on which, alternatively, beam pre-profiles and blooms are cast. It is customary to provide a strand guide with rollers for guiding the web of the carrier pre-profiles or a strand guide with rollers for guiding the bloom. Depending on the type of strand to be cast, the strand guides are removed and installed or replaced. This is economically disadvantageous due to the necessary exchange work.

Die Erfindung setzt sich zum Ziel, eine Strangführung derart auszubilden, dass beide Strangarten ohne Ausbau dieser Strangführungen auf einer Stranggiessanlage gegossen werden können. Dadurch sollte die Wirtschaftlichkeit der Stranggiessanlage bei erhöhter Produktivität und niedrigeren Kosten gesteigert werden.The aim of the invention is to design a strand guide in such a way that both types of strand can be cast on a continuous casting installation without removing these strand guides. This should increase the economy of the continuous caster with increased productivity and lower costs.

Dieses Ziel wird gemäss der Erfindung dadurch erreicht, dass an zwei Seiten eines dreh- oder schwenkbaren Trägers je eine Rolle zur Führung des Steges eines Träger-Vorprofiles oder eine Rolle zur Führung eines Vorblockes angeordnet sind. Mit einer derartigen Vorrichtung kann das alternative Giessen von Strängen der vorgenannten unterschiedlichen Art wirtschaftlich, d.h. wenig zeit-und arbeitsaufwendig durchgeführt werden.This object is achieved according to the invention in that a roller for guiding the web of a carrier pre-profile or a roller for guiding a pre-block is arranged on two sides of a rotatable or pivotable carrier. With such a device, the alternative casting of strands of the aforementioned different types can be economically, i.e. can be carried out in little time and labor.

  • Fig. 4 is a plan view of another embodiment.

Gemäss Fig. 1 ist in der Sekundärkühlzone einer Stranggiessanlage ein Träger-Vorprofil 1 durch Rollen 2 am Steg und durch Rollen 4 an den Flanschseiten geführt. Die Rollen 2 sind, jeweils an einer Seite der Träger, an einem inneren Träger 5 und am äusseren Träger 6, die Rollen 4 an seitlichen Trägern 3 gelagert. An den Trägern 5 und 6 ist auf der, der Rolle 2 abgewandten Seite jeweils eine Rolle 7 zur Führung eines Vorblockes angebracht.1, in the secondary cooling zone of a continuous casting installation, a carrier pre-profile 1 is guided by rollers 2 on the web and by rollers 4 on the flange sides. The rollers 2 are mounted on one side of the carrier, on an inner carrier 5 and on the outer carrier 6, and the rollers 4 are supported on side carriers 3. On the supports 5 and 6 on the side facing away from the roll 2 there is in each case a roll 7 for guiding a bloom.

Die Träger 3 sind verschiebbar an einem Rahmen 9 durch Stellschrauben 8 gehalten.The carrier 3 are slidably held on a frame 9 by adjusting screws 8.

Die Träger 5 und 6 sind um Achsen 11 drehbar. Die Drehung erfolgt, wie aus Fig. 2 ersichtlich, über einen Antrieb 10. Mit 12 sind die Lager für die Achsen 11 bezeichnet.The carriers 5 and 6 are rotatable about axes 11. As can be seen from FIG. 2, the rotation takes place via a drive 10. The bearings for the axes 11 are designated by 12.

Für den inneren und äusseren Träger 5 und 6 sind Halterungen 14 am Rahmen 9 vorgesehen. Mit 15 sind Fixierschrauben bezeichnet, die die Halterungen 14 an die Träger 5 und 6 drücken und eine ungewollte Drehung derselben verhindern und diese positionieren.Brackets 14 are provided on the frame 9 for the inner and outer supports 5 and 6. With 15 fixing screws are designated, which press the brackets 14 on the carrier 5 and 6 and prevent an unwanted rotation of the same and position them.

Soll, statt des gezeichneten Träger-Vorprofiles 1, ein Vorblockformat 16 gegossen werden, werden die Stellschrauben 8 gelöst und die Flanschrollen 4 in Pfeilrichtung 17 verschoben. Danach werden die Schrauben 15 gelöst, um die Halterungen 14 des äusseren Trägers 6 zu lösen. Hierauf wird die Achse 11 um 180 in Pfeilrichtung 18 durch den Antrieb 10 gedreht, wodurch sich die Positionen der Rolle 2 und der Rolle 7 vertauschen. Eine manuelle Drehung ist ebenfalls möglich. Nachfolgend wird in gleicher Weise der innere Träger 5 gedreht. Nach vollzogener Drehung beider Träger 5 und 6 werden sie durch die Halterungen 14 aufgenommen und diese mit den Schrauben 15 gesichert. Fig. 3 zeigt den Endzustand der Strangführung, bereit zum Giessen eines Vorblockes.If, instead of the pre-section 1 shown in the drawing, a pre-block format 16 is to be cast, the set screws 8 are loosened and the flange rollers 4 are shifted in the direction of arrow 17. Then the screws 15 are loosened in order to loosen the brackets 14 of the outer carrier 6. The axis 11 is then rotated 180 in the direction of the arrow 18 by the drive 10, as a result of which the positions of the roller 2 and the roller 7 are interchanged. Manual rotation is also possible. The inner support 5 is subsequently rotated in the same way. After the rotation of both supports 5 and 6, they are received by the brackets 14 and secured with the screws 15. Fig. 3 shows the final state of the strand guide, ready for casting a bloom.

Falls es die Grösse der Vorblockformate erlaubt, den Strang nur auf einer Seite, z.B. der äusseren Seite, zu führen, kann die Rolle 7 am inneren Träger 5 auch weggelassen werden.If the size of the bloom format allows, the strand only on one side, e.g. on the outer side, the roller 7 on the inner carrier 5 can also be omitted.

Die seitlichen Rollen 4 können bei Bedarf durch Verschieben der Träger 3 in Pfeilrichtung 19 zur seitlichen Führung des Vorblockes 16 herangezogen werden.The lateral rollers 4 can, if necessary, be moved by moving the carrier 3 in the direction of arrow 19 for lateral guidance of the bloom block 16.

Fig. 4 zeigt eine weitere Ausführungsform, wobei am äusseren Träger 6' die Rolle 2, zur Führung des Steges eines Träger-Vorprofiles 1 sowie auf einer weiteren Seite des Trägers eine Rolle 7 zur Führung des Vorblockes angeordnet sind. Beim Übergang des Giessens von einer Strangart zur anderen muss dieser Träger nur um 90° in Pfeilrichtung 20 verschwenkt werden, um die gewünschte Rolle in Arbeitsposition zu bringen. Die gegenüberliegende Rolle zum Führen des Steges des Träger-Vorprofiles wird weggelassen.4 shows a further embodiment, the roller 2 for guiding the web of a carrier pre-profile 1 and a roller 7 for guiding the pilot block being arranged on the outer carrier 6 '. When casting from one type of strand to another, this carrier only has to be pivoted through 90 ° in the direction of arrow 20 in order to bring the desired roll into the working position. The opposite roller for guiding the web of the carrier pre-profile is omitted.
