Description

Die Erfindung betrifft eine Vorrichtung für einen kurzen Anfahrstrang, der aus einer Aufnahme etwa horizontal zwischen im Bogenverlauf einer Bogenmetallstranggießanlage angeordneten Treiberrollen durch eine Öffnung im Rollengerüst bzw. in der Kühlkammer einführbar ist.The invention relates to a device for a short start-up strand, which can be inserted from a receptacle approximately horizontally between driver rollers arranged in the arc shape of a sheet metal continuous casting installation, through an opening in the roller stand or in the cooling chamber.

Kurze Anfahrstränge werden in einer Metallstranggießanlage, insbesondere in Stahlstranggießanlagen, die in Bogenform gebaut sind, entweder von der Gießbühen aus, auf einem Transportwagen aufliegend in die Stranggießkokille von oben eingeführt (DE-AS 19 61 443) oder aber, um das Hindurchführen des gesamten Anfahrstranges durch die STranggießkokille hindurch zu vermeiden, durch eine Öffnung der Kühlkammer bzw. des Rollengerüstes zwischen angetriebene Rollen des Stützrollengerüsts eingeführt. Eine Anfahrstrangvorrichtung des zweiten Typs ist aus der DE-AS 15 08 758 bekannt. Die vorliegende Erfindung betrifft gattungsgemäß eine Anfahrstrang-Vorrichtung des zweiten Typs.Short approach strands are introduced in a metal continuous casting plant, in particular in steel continuous casting plants, which are built in an arc shape, either from the casting platform, lying on a trolley lying in the continuous casting mold from above (DE-AS 19 61 443) or, in order to pass the entire starting strand to avoid through the continuous casting mold, inserted through an opening of the cooling chamber or the roller stand between driven rollers of the support roller stand. A start-up train device of the second type is known from DE-AS 15 08 758. The present invention relates generally to a start-up train device of the second type.

Nach dem Stand der Technik (DE-AS 15 08 758) ist eine über dem Treibrichtaggregat ortsfest angeordnete Vorrichtung für einen kurzen Anfahrstrang bekannt. Nachteilig bei dieser Lösung ist es, daß ein aufwendiger Antrieb für das Einfördern des Anfahrstranges erforderlich ist. Ferner ist der Raum aufgrund der ortsfest angeordneten Vorrichtung neben der Kühlkammer bzw. über dem Treibrichtaggregat dauernd belegt. In diesem Raum ist eine Wartung des Anfahrstranges äußerst problematisch.According to the state of the art (DE-AS 15 08 758), a device for a short start-up line, which is arranged in a stationary manner above the drive leveling unit, is known. The disadvantage of this solution is that a complex drive is required to feed the starting line. Furthermore, due to the stationary device next to the cooling chamber or above the drive leveling unit, the space is permanently occupied. Maintenance of the start-up line is extremely problematic in this room.

Der Erfindung liegt daher die Aufgabe zugrunde, Wartungsarbeiten während der Gießzeiten am Anfahrstrang außerhalb des Heißbereiches durchführen zu können und den Anfahrstrang einfahrbereit mit der Kopfseite in Einförderrichtung bringen zu können.The invention is therefore based on the object of being able to carry out maintenance work during the casting times on the start-up strand outside the hot zone and to be able to bring the start-up strand with the head side in the feed direction ready for entry.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöste, daß die Aufnahme auf einer quer zur Gießrichtung verlaufenden Schienenbahn verfahrbar ist und eine Einförderebene und eine Ablageebene aufweist, wobei Einförderebene und Ablageebene miteinander durch ein den Anfahrstrang umlenkendes Transportmittel verbunden und in übereinander befindlichen Höhenlagen angeordnet sind. Vorteilhafterweise kann die Wartung aufgrund der erfindungsgemäßen Lösung außerhalb des Heißbereiches erfolgen, und der Anfahrstrang kann, obgleich et mit der Endseite in Bewegungsrichtung aus dem Treibrichtaggregat ausgezogen wird, wieder mit dem Anfahrkopf-Ende in die Einförderbahn gebracht werden.The object is achieved according to the invention in that the receptacle can be moved on a rail track running transversely to the casting direction and has an infeed level and a storage level, the infeed level and storage level being connected to one another by a transport means deflecting the start-up line and arranged at high altitudes. Due to the solution according to the invention, the maintenance can advantageously be carried out outside the hot area, and although the end side is pulled out in the direction of movement from the drive-direction unit, the start-up strand can be brought back into the feed-in path with the start-up head end.

In Ausgestaltung der Erfindung wird vorgeschlagen, daß die Aufnahme aus waagerechten Rahmenteilen und senkrechten Rahmenteilen besteht, wobei die Einförderebene aus einem horizontalen Rahmenteil und die Ablageebene aus dem horizontalen Rahmenteil mit jeweils angeordneten Rollenpaaren besteht, wobei zwischen den Rollenpaaren eine um Kettenräder geführte Antriebskette mit Mitnehmern vorgesehen ist. Eine solche Bauweise ist sehr leicht und erlaubt entsprechend wirtschaftlich dimensionierte und betreibbare Antriebsorgane.In an embodiment of the invention it is proposed that the receptacle consists of horizontal frame parts and vertical frame parts, the infeed plane consisting of a horizontal frame part and the storage plane consisting of the horizontal frame part, each with pairs of rollers arranged, with a drive chain with carriers guided around chain wheels being provided between the roller pairs is. Such a construction is very light and allows correspondingly economically dimensioned and operable drive elements.

Das Einrichten der Aufnahme auf eine oder mehrere Strangadern wird außerdem dadurch erleichtert, daß in Fahrtrichtung der Aufnahme parallel nebeneinander im Abstand mehrerer paralleler Gießadern jeweils Rollenpaare bzw. Rollen, Kettenräder und Antriebsketten vorgesehen sind.Setting up the receptacle on one or more stranded wires is also facilitated in that, in the direction of travel of the receptacle, roller pairs or rollers, sprockets and drive chains are provided in parallel next to one another at a distance from several parallel cast wires.

Der Anfahrstrang kann besonders vorteilhaft in die Auflageebene transportiert werden, wenn an dem der Einförderseite gegenüberliegenden Ende der Aufnahme jeweils eine Hubvorrichtung über der Ablageebene und jeweils tangential zu einem Kettenrad mit Kette am Rahmenteil der Einförderebene eine vertikale Führungsschiene vorgesehen sind.The starting strand can be transported particularly advantageously into the support plane if a vertical guide rail is provided at the end of the receptacle opposite the feed side, in each case a lifting device above the storage plane and tangential to a chain wheel with chain on the frame part of the feed plane.

Hierbei werden die Bahnen für die Ablageebene oder für die Einförderebene dadurch festgelegt, daß dem den Anfahrstrang umlenkenden Transportmittel zwischen der Ablageebene und der Einförderebene eine die Einförderebene freigebende oder verschließende Weiche zugeordnet ist.Here, the paths for the storage level or for the infeed level are determined by assigning a switch which releases or closes the infeed level to the transport means deflecting the start-up line between the storage level and the infeed level.

An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it
  • 1 is a side view of a continuous sheet steel caster with cooling chamber and device for a short start-up strand,
  • 2 is a side view of the recording for a short start-up line in the recording phase,
  • 3 shows a cross section through the receptacle for several start-up lines,

In der Bogenstahlstranganlage 1 wird die Metallschmelze in eine Stranggießkokille 2 eingegossen, nachdem zuvor der relativ kurze Anfahrstrang 3 von unten in die Stranggießkokille 2 eingefahren worden ist und eine Abdichtung 4 am Rande des Gießquerschnitts eingefügt wurde. Das Einfahren des relativ kurzen Anfahrstranges 3 erfolgt aus einer Aufnahem 5, die über dem Treib-Richt-Aggregat 6 und neben einer Kühlkammer 7 in Stellung gebracht wird. Die Kühlkammer 7 weist für den Einfahrvorgang eine Klappe 8 auf, und bei geöffneter Klappe 8 wird der Anfahrstrang 3 über eine Führung 9 durch eine Öffnung 10 bis in den Wirkbereich von Treiberrollen 11 und von diesen zwischen Stützrollenpaare 12a des Rollengerüstes 12 mit dem Anfahrkopf 13 voraus in den Eingangsbereich der Stranggießkokille 2 geschoben. Bei Gießbeginn werden sodann die Treiberrollen 11 solange durch den Drehantrieb 14 (nur angedeutet) beaufschlagt, bis der Anfahrstrang 3 zusmamen mit dem daran hängenden Gußstrang (nicht sichtbar) in den Wirkbereich des Treib-Richt-Aggregats 6 gelangt. Nachdem der Anfahrstrang 3 mit seinem rückwärtigen Ende 3a das letzte Antriebswalzenpaar 6a in Gießrichtung 15 passierthat, wird er an einer Öse 3b an einem Fanghaken 16a einer Hubvorrichtung 16 hängend in die Aufnahme 5 transpottiert (Fig. 2).In the sheet steel extrusion plant 1, the molten metal is poured into a continuous casting mold 2 after the relatively short start-up strand 3 has been inserted into the continuous casting mold 2 from below and a seal 4 has been inserted at the edge of the casting cross section. The relatively short start-up line 3 is brought in from a receptacle 5, which is brought into position above the drive-straightening unit 6 and next to a cooling chamber 7. The cooling chamber 7 has a flap 8 for the retraction process, and when the flap 8 is open, the start-up strand 3 is guided in advance via a guide 9 through an opening 10 into the effective area of driver rollers 11 and from there between support roller pairs 12a of the roller stand 12 pushed into the entrance area of the continuous casting mold 2. At the start of casting, the driver rollers 11 are then acted upon by the rotary drive 14 (only indicated) until the Starting strand 3 together with the cast strand attached to it (not visible) reaches the effective range of the drive-straightening unit 6. After the start-up strand 3 with its rear end 3a has passed the last pair of drive rollers 6a in the casting direction 15, it is transposed hanging on an eyelet 3b on a catch hook 16a of a lifting device 16 into the receptacle 5 (FIG. 2).

Die Aufnahme 5 (Fig. 2 bis 6) ist auf einer quer zur Gießrichtung 15 verlaufenden Schienenbahn 17 in der Art einer Kranbahn verfahrbar.The receptacle 5 (FIGS. 2 to 6) can be moved on a rail track 17 running transversely to the casting direction 15 in the manner of a crane runway.

Die Aufnahme 5 weist ferner eine Einförderebene 18 und eine darüberliegende Ablageebene 19 auf.The receptacle 5 also has an infeed level 18 and an overlying storage level 19.

Der weitere Aufbau der Aufnahme 5, die kurze Rüstzeiten für den Anfahrstrang 3 gewährleistet und eine aufwendige Stahlkonstruktion zur Lagerung von längeren Anfahrsträngen vermeidet, ist wie folgt gegliedert: Die Aufnahme 5 wird durch fest verbundene waagerechte Rahmenteile 20, 21 und 22 sowie durch senkrechte Rahmenteile 23, 24 und 25 gebildet. Hierbei weist der horizontale Rahmenteil 22 die Einförderebene 18 auf und der horizontale Rahmenteil 21 die Ablageebene 19. Die Ablageebene 19 trägt Rollenpaare 26. Die Einförderebene 18 wird durch Rollen 26a gebildet. Auf der Einförderebene 18 abgestützt, jedoch beiden Ebenen durch Abstimmung des Durchmessers und der Umfangsanordnung zugeordnet, sind an den Enden der Aufnahme 5 jeweils Kettenräder 27 und 28 drehgelagert. Über ein Paar solcher Kettenräder verläuft eine Antriebskette 29, an der zumindest ein Mitnehmer 30 befestigt ist. Die Kette 29 bzw. das Kettenrad 27 ist mittels des Getriebes 31 und eines über eine Kupplung 32 verbundenen Motors 33 angetrieben.The further structure of the receptacle 5, which ensures short set-up times for the start-up line 3 and avoids a complex steel structure for storing longer start-up lines, is structured as follows: The mount 5 is made up of firmly connected horizontal frame parts 20, 21 and 22 and vertical frame parts 23 , 24 and 25 are formed. Here, the horizontal frame part 22 has the infeed plane 18 and the horizontal frame part 21 has the storage level 19. The storage level 19 carries pairs of rollers 26. The infeed level 18 is formed by rollers 26a. Supported on the infeed plane 18, but assigned to both planes by coordinating the diameter and the circumferential arrangement, sprockets 27 and 28 are rotatably supported at the ends of the receptacle 5. A drive chain 29, to which at least one driver 30 is attached, runs over a pair of such chain wheels. The chain 29 or the sprocket 27 is driven by means of the transmission 31 and a motor 33 connected via a clutch 32.

Für eine Mehrstranggießanlage sind im Abstand mehrerer paralleler Gießadern (Fig. 3) in den Fahrtrichtungen 34 der Aufnahme 5 jeweils Kettenräder 27, 28 und separate Getriebe 31 mit Motoren 33 vorgesehen. Jeder Gießader ist auch jeweils eine Hubvorrichtung 16 zugeordnet.For a multi-strand caster, sprockets 27, 28 and separate gears 31 with motors 33 are provided in the directions of travel 34 of the receptacle 5 at a distance from a plurality of parallel casting lines (FIG. 3). A lifting device 16 is also assigned to each casting wire.

Die Aufnahme 5 ist mittels der Räderpaare 35 und 36 und des Fahrantriebs 37 verfahrbar (Fig. 3 und 4). Am Rahmenteil 20 ist außerdem ein Vorsprung 38 für die Hubvorrichtung 16 gebildet. Der Einförderseite 39 gegenüber, am Ende 5a der Aufnahme 5, ist am Rahmenteil 22 eine vertikale Führungsschiene 40 vorgesehen. Das Transportmittel für den Anfahrstrang 3 lenkt den Anfahrstrang 3 in der in Fig. 2 gezeichneten Phase mittels der Weiche 41 in die Auflageebene 19 um, so daß das eine Ende 3a des Anfahrstranges 3 mit der Öse 3b in die Auflageebene 19 einläuft. Die Weiche 41 besteht aus der Zunge 42, die um die Achse 43 einer Rolle 26a schwenkbar gelagert ist. Der Anfahrstrang 3 wird bis in die Lage gemäß Fig. 5 hochgezogen, in der er auf der Auflageebene 19 liegt. Zum Transport in die Einförderebene 18 in Transportrichtung 44 wird die Weiche 41 umgestellt (Fig. 6), so daß der Motor 33 die Kette 29 mit dem Anfahrstrang 3 in die Einförderebene 18 transportiert. Der Anfahrstrang 3 gelangt auf diese Art mit dem Anfahrkopf 13 in Einförderrichtung 44 in die Führung 9 und in die Öffnung 10 und damit zwischen die Treiberrollen 11, wie eingangs beschrieben.The receptacle 5 can be moved by means of the pairs of wheels 35 and 36 and the travel drive 37 (FIGS. 3 and 4). A projection 38 for the lifting device 16 is also formed on the frame part 20. A vertical guide rail 40 is provided on the frame part 22 opposite the feed side 39, at the end 5a of the receptacle 5. The transport means for the start-up line 3 deflects the start-up line 3 in the phase shown in FIG. 2 by means of the switch 41 into the support level 19, so that one end 3a of the start-up line 3 runs into the support level 19 with the eyelet 3b. The switch 41 consists of the tongue 42 which is pivotally mounted about the axis 43 of a roller 26a. The starting strand 3 is pulled up to the position shown in FIG. 5, in which it lies on the support plane 19. For transport in the feed plane 18 in the transport direction 44, the switch 41 is changed over (FIG. 6), so that the motor 33 transports the chain 29 with the starting strand 3 into the feed plane 18. In this way, the start-up strand 3 arrives with the start-up head 13 in the feed-in direction 44 into the guide 9 and into the opening 10 and thus between the driver rollers 11, as described at the beginning.
