Rahmens oder des Gerüstes für mehrere Rollen zu Segmenten
zusammenzufassen, wobei die Segmentrahmen aus zwei die Rollen
tragenden Jochrahmen bestehen und die Jochrahmen über Zuganker
und Distanzstücke auf das Gießformat einstellbar sind.From
Bei herkömmlichen Strangführungsgerüsten in Segmentbauweise
nach der in der DE 19 63 146 C1 beschriebenen Art werden bei
Bogenanlagen die Ober- und Unterrahmen der Segmente durch vier
an den Ecken außerhalb der Strangbahn angeordnete, die Rahmen
verbindende HydrauLik-Differentialzylinder

Die DE 43 06 853 C2 offenbart eine Strangführung an Stranggießanlagen für die Erzeugung von Brammen, insbesondere nach dem Gießwalzverfahren, mit auf unterschiedliche Strangdicken einstellbaren, paarweise gegenüberliegenden Rollen, die an durch Zuganker verbundenen Rahmen- oder Gerüstteilen der Strangführung gelagert und deren Zuganker von Kolben/Zylinder-Einheiten gebildet und wobei im Kraftfluss der Kolben-Zylinder-Einheit zwischen oberen und unteren Rahmenteilen Distanzstücke eingelegt sind. Diese als Zuganker ausgebildeten KoLben/Zylinder-Einheiten erfordern eine kardanische Lagerung und sind als Hydraulik-Ring-Zylinder ausgebildet, der die Kolbenstange umgibt und dessen Ringkolben ein extrem aufwendiges Bauteil darstellt. Darüber hinaus hat die bekannte Bauart den Nachteil, dass die Stellmittel ebenso wie die zugeordneten Weggeber an den Segmenten angeordnet sind und bei Austausch oder Überholung der Segmente zusammen mit ihren Anschlüssen mit ausgebaut werden müssen. Dies erfordert einerseits wegen der aufwendigen Bauweise der als Zuganker ausgebildeten hydraulischen Kraftmittel und andererseits wegen ihrer Anordnung innerhalb der Segmente nicht nur erhöhte Fertigungskosten, sondern insbesondere unerwünschte Ausfallzeiten der Anlage bei Reparatur- oder Wartungsarbeiten an der Stützführung.DE 43 06 853 C2 discloses a strand guide Continuous casting plants for the production of slabs, in particular after the casting and rolling process, with different Adjustable strand thicknesses, opposed in pairs Rollers connected to frame or by tie rods Scaffold parts of the strand guide stored and their tie rods from Piston / cylinder units formed and being in the power flow of the Piston-cylinder unit between the upper and lower Frame parts spacers are inserted. This as a tie rod trained piston / cylinder units require one gimbal mounting and are called hydraulic ring cylinders trained, which surrounds the piston rod and the annular piston represents an extremely complex component. It also has the known design has the disadvantage that the adjusting means as well how the assigned position sensors are arranged on the segments and when replacing or overhauling the segments together with their connections need to be expanded. This requires on the one hand because of the complex construction of the as a tie rod trained hydraulic power and on the other hand because their arrangement within the segments not only increased Manufacturing costs, but especially undesirable Downtime of the system during repair or maintenance work on the support guide.

Jedem Segment sind am oberen und unteren Bereich einer Schmalseite mit dem Fundamentrahmen (10) verbundene Träger (11, 12) zur Aufnahme sowohl des losseitigen (5), als auch des festseitigen (4) Rahmens zugeordnet. Dem festseitigen Rahmen (4) sind in jeweils einer oberen und einer unteren Querschnittsebene (A-A) an einem Ende jedes Trägers (11, 12) in der Passlinie (x-x) feste Anschläge (13, 14) und im Abstand von diesen Anschlägen (13, 14) am Träger (11, 12) Plunger (15, 16) zum Andrücken des Rahmens (4) gegen diese Anschläge (13, 14) zugeordnet. Am gegenüberliegenden Ende jedes Trägers (11, 12) ist je ein mit dem losseitigen Rahmen (5) zusammenwirkender hydraulischer Stellzylinder (6, 7) angeordnet. Zwischen beiden Rahmen (4, 5) sind Spreizfedern (8, 9) eingespannt.Each segment is one at the top and bottom Narrow side connected to the foundation frame (10) (11, 12) for receiving both the loose side (5) and the associated (4) frame. The fixed frame (4) are in an upper and a lower one Cross-sectional plane (A-A) at one end of each beam (11, 12) Fixed stops (13, 14) in the pass line (x-x) and at a distance of these stops (13, 14) on the carrier (11, 12) plunger (15, 16) for pressing the frame (4) against these stops (13, 14) assigned. At the opposite end of each beam (11, 12) is one with the loose frame (5) interacting hydraulic actuating cylinder (6, 7) arranged. Spreading springs are between the two frames (4, 5) (8, 9) clamped.
Mit großem Vorteil werden die Segmente dadurch vereinfacht und in ihrem Gewicht erheblich entlastet, dass die als Kraftmittel vorgesehenen Stellzylinder (6, 7) sowie die Plunger (15, 16) und die Weggeber (17, 18) mit ihren hydraulischen und ggf. elektrischen Anschlüssen an Führungsträgern (11, 12), mit dem Fundamentrahmen (vgl. 10, Fig 2) fest verbunden sind und bei Montagearbeiten, beispielsweise Rollenwechsel, nicht mit ausgebaut bzw. ausgetauscht werden müssen. Besonders vorteilhaft wirkt sich hierbei die Tatsache aus, dass die elektrischen und hydraulischen Anschlüsse bei derartigen Wartungsarbeiten nicht mit demontiert und remontiert werden müssen, wodurch Zeit und Kosten erspart werden und das Spülen bei Neuanschlüssen entfällt.The segments are thereby simplified and greatly advantageous Relieved in weight that as a means of strength provided actuating cylinders (6, 7) and the plungers (15, 16) and the displacement sensors (17, 18) with their hydraulic and possibly electrical connections to guide carriers (11, 12), with the Foundation frame (see Fig. 10, Fig 2) are firmly connected and at Assembly work, for example changing roles, not with must be removed or replaced. Especially The fact that the electrical and hydraulic connections in such Maintenance work must not be dismantled and reassembled need, which saves time and money and rinsing in the case of new connections.

Schaltorgane ortsfest an den Trägern (11, 12) bzw. am Fundamentrahmen (10) angeordnet sein können und bei Wechsel oder überholung eines Segmentes nicht mit demontiert werden müssen. Die Stützführung nach der Erfindung sieht weiterhin vor, dass die Weggeber (17, 18) mit pneumatisch ausfahrbaren Kolben/Zylinder-Einheiten ausgebildet sind. Weiterhin ist vorgesehen, dass die Träger (11, 12) zur Aufnahme und Übertragung der über die Rahmen (4, 5) auf sie einwirkenden Kräfte entsprechend formstabil ausgebildet sind.As a result of the arrangement of both the plungers (15, 16) and hydraulic actuating cylinder (6, 7) and the displacement sensor (17, 18) on the beams (11,) connected to the foundation frame (10) 12) there is the further advantage that this assignable hydraulic and / or electrical connections or switching elements stationary on the carriers (11, 12) or on Foundation frame (10) can be arranged and when changing or overhaul of a segment cannot be dismantled have to.

Dabei besteht das Kraftsystem zur geregelten Dickeneinstellung des Gussstranges (1) bevorzugt aus Servo-geregelten Stellzylindern (6, 7), welche die Losseite des Rahmens (5) auf Passdicke (D) zur "Null"-Justierung drücken. Das Messsystem nimmt dabei die Nullungs-Lage auf, wenn die Distanzstücke (19, 20) auf gegenseitige Flächenberührung (ohne Strang (1)) gegeneinander zusammengefahren sind.As shown in Figures 2 and 3, are on the frame (4, 5) each other opposing spacers (19, 20) arranged, the for the purpose of adjusting a defined position of the frames in a zero position can be moved together. Here is what Force system for regulated thickness adjustment of the cast strand (1) preferably from servo-controlled actuating cylinders (6, 7), which the loose side of the frame (5) to fit thickness (D) Press "zero" adjustment. The measuring system takes that Zeroing position when the spacers (19, 20) on mutual surface contact (without strand (1)) against each other are moved together.
Infolge Anordnung der Stell- und Messmittel (7, 8) bzw. (17, 18) sowie (15, 16) an ortsfest mit dem Fundamentrahmen (10) verbundenen Trägern (11, 12) ist kein hydraulisches oder elektrisches Kuppeln beim Segmentwechsel erforderlich. Auch können beliebige Dicken zwischen Minimum und Maximum während des Laufenden Betriebes mit dem Gießstrang (1) eingestellt werden. Weiterhin ist mit Vorteil vorgesehen, dass die Stellzylinder (6, 7) mit Weg-Kraft-Regelung ausgebildet sind. Und schließlich ergibt sich mit der Erfindung der Vorteil, dass Stellzylinder (6, 7), Weggeber (17, 18), und Plunger (15, 16) außerhalb der Kühlkammer (25) angeordnet sind.As a result of the arrangement of the adjusting and measuring means (7, 8) or (17, 18) and (15, 16) on stationary with the foundation frame (10) connected beams (11, 12) is not a hydraulic or electrical coupling required when changing segments. Also can have any thickness between minimum and maximum during the ongoing operation with the casting strand (1) set become. It is also advantageously provided that the Actuating cylinders (6, 7) are designed with displacement force control. And finally, with the invention, there is the advantage that actuating cylinder (6, 7), displacement sensor (17, 18), and plunger (15, 16) are arranged outside the cooling chamber (25).
