Description

Vorrichtung für die Stützung und Oszillation einer Stranggießkokille zum Gießen von flüssigem Metall, insbesondere von flüssigem StahlwerkstoffDevice for the support and oscillation of a continuous casting mold for the casting of liquid metal, in particular of liquid steel material
Die Erfindung betrifft eine Vorrichtung für die Stützung und Oszillation einer Stranggießkokille zum Gießen von flüssigem Metall, insbesondere von flüssi¬ gem Stahlwerkstoff, mit beidseitig zu einer Symmetrie-Ebene, in der die Mittel¬ längsachse des Gießstrangs verläuft, angeordnete Führungselemente, die an ortsfesten Tragbauteilen gelagert sind, wobei die Stranggießkokille jeweils beidseitig auf Führungselementen und zumindest einer Oszillationseinrichtung abgestützt ist.The invention relates to a device for the support and oscillation of a continuous casting mold for casting of liquid metal, in particular of flüssi¬ gem steel material, arranged on both sides to a plane of symmetry, in which the Mittel¬ longitudinal axis of the cast strand, arranged guide elements arranged on stationary support components are stored, wherein the continuous casting mold is supported on both sides on guide elements and at least one oscillating device.
Derartige Vorrichtungen bewegen große Massen, die aus dem Gewicht der Stranggießkokille mit Seitenwänden (Schmalseitenplatten), einer Stützkonstruk¬ tion für die Seitenwände, für Wasserkästen, eines Hubtisches mit beidseitig an¬ geordneten Führungselementen und Oszillationsantrieben bestehen. Hinzu kommt die Reibungskraft zwischen den Gießstrangflächen und den Kokillen¬ wänden beim Abwärtshub der Oszillationsantriebe. Die Abstützung solcher Vor- richtungen wird insgesamt sehr schwer und erfordert zudem einen hohen Platz¬ bedarf, so dass die Zugänglichkeit der durch Verschleiß belasteten Baugruppen und Bauteile erschwert wird. Ein langwieriges Demontieren oder Montieren auszutauschender oder zu wartender Bauteile bedeutet jedoch einen ebenso langzeitigen Stillstand der Stranggießmaschine. Dadurch entstehen erhebliche wirtschaftliche Nachteile.Such devices move large masses, which consist of the weight of the continuous casting mold with side walls (narrow side plates), a Stützkonstruk¬ tion for the side walls, for water tanks, a lifting table with both sides an¬ ordered guide elements and oscillating drives. Added to this is the frictional force between the cast strand surfaces and the mold walls during the downward stroke of the oscillatory drives. The support of such devices is generally very difficult and also requires a high Platz¬ required, so that the accessibility of the loaded by wear assemblies and components is difficult. However, a lengthy dismantling or mounting exchangeable or serviceable components means an equally long-term stoppage of the continuous casting machine. This creates significant economic disadvantages.
Der Erfindung liegt die Aufgabe zugrunde, durch eine entsprechende konstruk¬ tive Gestaltung die Wartungs-, Demontage- und Montage-Zeiten zu verkürzen und dadurch Ausfall-Zeiten und -Kosten zu senken. Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine erste Baugruppe aus Führungselementen und Tragbauteilen gebildet ist und eine zweite Baugruppe aus der Oszillationseinrichtung besteht, wobei die zweite Baugruppe durch einen seitlichen, quer zur Symmetrie-Ebene verlaufenden Ausgang bzw. Eingang unterhalb der Führungselemente oder zwischen Füh- rungselementen ausbaubar ist und wobei jede der beiden Baugruppen zeitlich und örtlich unabhängig von der jeweils anderen Baugruppe demontierbar oder wieder montierbar ist. Dadurch wird die Zugänglichkeit der wesentlichen Bau¬ gruppen und Bauteile erhöht und eine kürzere Ausfallzeit erzielt. Der Hauptvor¬ teil ist jedoch dadurch erreicht, dass unabhängig davon, ob eine Baugruppe für Führungselemente oder die Oszillationseinrichtung häufiger gewechselt werden muss, jeweils die kürzere Wartungs- oder Wechselzeit genutzt werden kann, weil eine bestimmte Reihenfolge der aufeinanderfolgenden Ausbau- Handlungen nicht mehr zwingend ist. Diejenige Baugruppe kann sofort ausge¬ baut und wieder eingebaut werden, die der Wartung bedarf. Weiterhin bestehen Vorteile dahingehend, dass durch ein früher ohne Wartung durchzuführendes Demontieren und Montieren kein Erfordernis für ein neues Ausrichten oder Ein¬ stellen der jeweils andersartigen Baugruppe entsteht, das von der Demontage, Montage oder Wartung nicht betroffen ist.The invention is based on the objective of shortening the maintenance, disassembly and assembly times by a corresponding constructive design and thereby reducing downtime and costs. The object is achieved according to the invention in that a first assembly of guide elements and supporting components is formed and a second assembly consists of the oscillation, wherein the second assembly by a lateral, transverse to the plane of symmetry output or input below the guide elements or between Füh- management elements is removable and wherein each of the two modules in time and place regardless of the other module is disassembled or reassembled. As a result, the accessibility of the essential Bau¬ groups and components is increased and achieved a shorter downtime. However, the main advantage is achieved in that regardless of whether an assembly for guide elements or the oscillation device has to be changed more frequently, the shorter maintenance or changeover time can be used in each case because a certain sequence of successive removal actions is no longer compulsory , The module can immediately be removed and rebuilt, which requires maintenance. Furthermore, there are advantages to the effect that disassembling and mounting without prior maintenance does not create a requirement for a new alignment or adjustment of the respective different type of assembly, which is not affected by disassembly, assembly or maintenance.
Eine Ausgestaltung ist auf die Verminderung der zu bewegenden Massen und damit auf die Reduzierung der Beanspruchung der Bauteile gerichtet und sieht vor, dass die erste Baugruppe mit Auslegern einer selbsttragenden Stranggie߬ kokille über die Führungselemente auf beabstandeten Lagerblöcken aufgestützt und befestigt ist.One embodiment is directed to the reduction of the masses to be moved and thus to the reduction of the stress on the components and provides that the first assembly with brackets of a self-supporting Stranggie߬ kokille is supported and fixed on the guide elements on spaced bearing blocks.
Der Fachmann ist bemüht, möglichst viele Bauteile zu einer Baugruppe zu¬ sammen zu fassen. Dazu wird vorgeschlagen, dass bei der ersten Baugruppe die Tragbauteile und die Führungselemente derart zu einer ausbaufähigen Ein¬ heit zusammengefasst sind, dass parallel zur Symmetrie-Ebene angeordnete Lagerblöcke vorgesehen sind, an denen die Führungselemente befestigt sind, die auch mit dem jeweiligen Ausleger der selbsttragenden Stranggießkokille in Verbindung stehen.The person skilled in the art endeavors to combine as many components as possible to form an assembly. For this purpose, it is proposed that in the first assembly the support components and the guide elements are combined into an expandable unit in such a way that bearing blocks arranged parallel to the plane of symmetry are provided on which the guide elements are fastened, which are also associated with the respective boom of the self-supporting continuous casting mold.
Die Anzahl der Bauteile kann nach weiteren Merkmalen dadurch reduziert wer¬ den, dass die Lagerblöcke jeweils zusammen einen einteiligen Wandrahmen bilden, die paarweise jeweils auf einer Zwischenplatte aufgestützt und befestigt sind.According to further features, the number of components can be reduced by the fact that the bearing blocks each together form a one-part wall frame, which are each supported and fastened in pairs on an intermediate plate.
Die angestrebte Verminderung der großen Massen und die Verbesserung der Zugänglichkeit zur Stranggießkokille und deren Funktionsgruppen und zu deren Wasserkasten und / oder der Schmalseitenplatten bei Brammen- Stranggießkokillen kann noch dadurch begünstigt werden, dass der Wandrah¬ men Ausnehmungen für den Zugang zur Kokillenschmalseite aufweist.The desired reduction of the large masses and the improvement of the accessibility to the continuous casting mold and their functional groups and their water tank and / or the narrow side plates in slab continuous casting molds can be further promoted by the Wandrah¬ men has recesses for access to the narrow side of the mold.
Die Baugruppe der Tragbauteile wird insbesondere bei gänzlichem Fehlen ei- nes Hubtisches oder eines entsprechend schweren Rahmens dadurch geprägt, dass die erste Baugruppe auch eine Deckplatte und eine Stützplatte mit Füh- rungsdornen für die Stranggießkokille umfasst.The assembly of the supporting components is characterized in particular in the total absence of a lifting table or a correspondingly heavy frame in that the first assembly also includes a cover plate and a support plate with guide thorns for the continuous casting mold.
Nach der weiteren Erfindung kann ein Anteil der sonst zwangsweise auszubau- enden Bauteile bei Wartung, Demontage oder Montage derart vermindert wer¬ den, dass eine ortsfeste Baugruppe aus einer Unterplatte, aus mehreren Stütz¬ wänden und einer Zwischenplatte gebildet ist, die auf einer am Stranggießge¬ rüst ortsfesten, lösbaren Grundplatte angeordnet ist.According to the further invention, a portion of the otherwise forcibly auszubau- to be removed components during maintenance, disassembly or assembly so wer¬ wer¬ that a stationary assembly of a lower plate, several Stütz¬ walls and an intermediate plate is formed on a continuous casting ¬ stationary stationary, releasable base plate is arranged.
Eine leichtere Zugänglichkeit der ortsfesten Tragbauteile wird ferner dadurch erreicht, dass auf der Zwischenplatte beidseitig Freiräume für die Oszillations- Bewegungen von blattfederförmigen Führungselementen angeordnet sind.Easier accessibility of the stationary support members is further achieved in that on the intermediate plate on both sides free spaces for the oscillatory movements of leaf spring-shaped guide elements are arranged.
Letztendlich kann auch nach einer hohen Anzahl von Gießvorgängen die ge- samte Anzahl von Bauteilen angebaut werden, indem die ortsfeste, lösbare Baugruppe mittels Bodenschrauben auf der ortsfesten Grundplatte befestigt ist. Der Ausbau oder Wiedereinbau des Oszillationsantriebs, der Paare von Oszilla¬ tionseinrichtungen umfassen kann, setzt eine Integration in den ortsfesten Be¬ reich voraus und sieht vor, dass die Oszillationseinrichtung jeweils im Grenzbe¬ reich zwischen der ersten ausbaufähigen Baugruppe und der ortsfesten Bau- gruppe auf einer Flansch-platte aufgestützt ist.Finally, even after a large number of casting operations, the entire number of components can be assembled by fixing the fixed, detachable subassembly on the fixed base plate by means of ground screws. The removal or replacement of the oscillation drive, which may include pairs of oscillation devices, requires integration into the fixed region and provides that the oscillation device in each case in the Grenzbe¬ rich between the first expandable assembly and the stationary assembly on a flange plate is supported.
Ein leichter, schneller und vollständiger Ausbau oder Einbau sieht vor, dass die zweite ausbaufähige Baugruppe zumindest eine Oszillationseinrichtung mit dem Kolben-Zylinder-Antrieb und Steuer- bzw. Schaltelemente umfasst.A lighter, faster and more complete removal or installation provides that the second expandable assembly comprises at least one oscillation device with the piston-cylinder drive and control or switching elements.
Von den vom Ausbau oder Einbau bei Wartungsarbeiten an Bauteilen oder Baugruppe ausgenommenen Bereichen ist einer der Kühlbereich der Strang¬ gießkokille, für den auf der Zwischenplatte ein ortsfester Aufbau mit Kühlwas¬ seranschlüssen vorgesehen ist.Of the areas excluded from dismantling or installation during maintenance work on components or subassemblies, one is the cooling zone of the strand casting mold, for which a stationary structure with cooling water connections is provided on the intermediate plate.
Bisherige Gestaltungen und Erfahrungen können im Kühlbereich der Strang¬ gießkokille derart berücksichtigt werden, dass die Kühlwasseranschlüsse je¬ weils an eine Wasseranschlussplatte, die auf der Zwischenplatte befestigt ist, geführt sind.Previous designs and experiences can be taken into account in the cooling area of the strand casting mold such that the cooling water connections are each guided to a water connection plate which is fastened on the intermediate plate.
Die Anzahl der auszubauenden Bauteile oder Baugruppen kann erforderlichen¬ falls dahingehend vergrößert werden, dass die ortsfeste Unterplatte und die Zwischenplatte mit den Aufbauten eine ortsfeste, lösbare Baugruppe bilden, die mittels Transportösen abgehoben oder aufgesetzt wird.The number of components or subassemblies to be removed can be increased if necessary to such an extent that the stationary subpanel and the intermediate plate with the superstructures form a stationary, detachable subassembly which is lifted or placed by means of lifting eyes.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt und wer¬ den nachfolgend näher erläutert. Es zeigen:Exemplary embodiments of the invention are illustrated in the drawing and are explained in more detail below. Show it:

Die Vorrichtung (Fig. 1 ) für die Stützung und Oszillation einer Stranggießkokille 1 dient zum Stranggießen von flüssigem Metall, insbesondere von flüssigem Stahlwerkstoff, mit beidseitig zu einer Symmetrie-Ebene 2, in der die Mittel¬ längsachse 3 des Gießstranges verläuft, angeordneten Führungselementen 4, die aus Exzentern, Lenkerhebeln, Federn jeder Art oder Blattfedern, wie ge¬ zeichnet, bestehen können. Die Führungselemente 4 sind an ortsfesten Trag¬ bauteilen 5 angelenkt, wobei die Stranggießkokille 1 jeweils beidseitig auf sol- chen Führungselementen und pro Seite zumindest auf einer Oszillationseinrich¬ tung 6 abgestützt ist. Die Oszillationseinrichtung 6 umfasst jeweils einen Kol¬ ben-Zylinder-Antrieb 6a (Fig. 2), Steuer- und Schaltmittel, wie bspw. Ventile und einen Hydraulikkreis.The device (FIG. 1) for the support and oscillation of a continuous casting mold 1 serves for the continuous casting of liquid metal, in particular of liquid steel material, with guide elements 4 arranged on both sides to a plane of symmetry 2, in which the central longitudinal axis 3 of the cast strand runs , which may consist of eccentrics, handlebar levers, springs of any kind or leaf springs, as ge draws. The guide elements 4 are articulated on stationary Trag¬ components 5, wherein the continuous casting mold 1 each on both sides on such guide elements and per page at least on one Oszillationseinrich¬ device 6 is supported. The oscillation device 6 comprises in each case a piston-cylinder drive 6a (FIG. 2), control and switching means, such as valves and a hydraulic circuit.
Gemäß den Fig. 1 bis 3 ist eine erste Baugruppe 7 aus den Führungselementen 4 und Tragbauteilen 5 gebildet. Eine zweite Baugruppe 8 besteht aus der Oszil¬ lationseinrichtung 6. Eine Besonderheit bildet die Gestaltung, dass die zweite Baugruppe 8 durch einen seitlichen, quer zur Symmetrie-Ebene 2 verlaufenden Ausgang 9 (oder Eingang) unterhalb der Führungselemente 4 oder zwischen Führungselementen 4 ausgebaut oder eingebaut werden kann. Die zweite aus¬ baufähige Baugruppe 8 wird mit ihrem Zylinder in einer seitwärts gerichteten Führungsbahn 9a gefahren und kann in einer Ausbaustellung gewartet, bspw. der Zylinder oder der Kolben des Kolben-Zylinder-Antriebs 6a können gewech¬ selt werden. Wesentlich ist noch, dass jede der beiden Baugruppen zeitlich und örtlich unabhängig voneinander demontiert und wieder montiert werden können. Die erste Baugruppe 7 braucht nicht entfernt zu werden. Umgekehrt kann der gesamte hydraulische Leitungskreis der zweiten Baugruppe 8 in der Vorrich¬ tung verbleiben und braucht nicht geöffnet zu werden, wenn nur Wartungsarbei¬ ten an der ersten Baugruppe 7 ausgeführt werden.According to FIGS. 1 to 3, a first assembly 7 of the guide elements 4 and support members 5 is formed. A second subassembly 8 consists of the oscillating device 6. A special feature is the design that the second subassembly 8 is removed or expanded below the guide elements 4 or between guide elements 4 by a lateral exit 9 (or entrance) running transversely to the symmetry plane 2 can be installed. The second ausbaufähige assembly 8 is driven with its cylinder in a sideways guide rail 9a and can be maintained in an extended position, for example. The cylinder or the piston of the piston-cylinder drive 6a can be gewech¬ Selt. It is also essential that each of the two modules can be disassembled and remounted independently of each other in terms of time and location. The first assembly 7 need not be removed. Conversely, the The entire hydraulic circuit of the second assembly 8 remain in the Vorrich¬ device and does not need to be opened when only Wartungsarbei¬ th on the first assembly 7 are executed.
Gemäß Fig. 1 stützt sich die Stranggießkokille 1 mit Auslegern 10 auf die erste Baugruppe 7, wobei die Stranggießkokille 1 nicht auf einem Hubtisch sitzt, son¬ dern über die Ausleger 10 unmittelbar auf den Führungselementen 4 aufliegt.According to FIG. 1, the continuous casting mold 1 with jibs 10 is supported on the first assembly 7, wherein the continuous casting mold 1 does not sit on a lifting table but rests directly on the guide elements 4 via the jibs 10.
In Fig. 2 ist der nähere Aufbau der ersten Baugruppe 7 gezeigt. Die Führungs¬ elemente 4, die als Tragbauteile 5 wirken, sind im Ausführungsbeispiel als Blatt- federpakete gewählt und mittig zwischen Lagerblöcken 11 und 12 (Fig. 1 ) bzw. an Lagerblöcken 18 und 19, die durch Zusammenlegung einen Wandrahmen 20 bilden, gelagert. Als ausbaufähige Einheit oder Baugruppe 13 werden bei dieser ersten Baugruppe 7 die Tragbauteile 5 und die Führungselemente 4 da¬ hingehend betrachtet, dass die parallel zur Symmetrie-Ebene 2 verlaufenden Lagerblöcke 18, 19 und damit der Wandrahmen 20 als oberes Stützlager und bei zwei Blattfederpaketen als Führungselemente 4 ein weiteres, unteres, je¬ weils mittig angeordnetes Stützlager bilden. Die jeweils äußeren Befestigungs¬ lager für die Führungselemente 4 sind an einer Deckplatte 21 mit einer Stütz¬ platte 22 befestigt, auf denen auch über Führungsdome 23 die Stranggießkokil- Ie 1 aufgenommen wird.In Fig. 2, the detailed structure of the first assembly 7 is shown. The guide elements 4, which act as supporting components 5, are selected in the exemplary embodiment as leaf spring assemblies and are mounted centrally between bearing blocks 11 and 12 (FIG. 1) or on bearing blocks 18 and 19, which form a wall frame 20 by merging. As an expandable unit or assembly 13, the support members 5 and the guide elements 4 are da¬ looking at this first assembly 7, that the parallel to the symmetry plane 2 extending bearing blocks 18, 19 and thus the wall frame 20 as an upper support bearing and two leaf spring assemblies as Guide elements 4 form a further, lower, je¬ Weils centrally arranged support bearing. The respective outer Befestigungs¬ bearings for the guide elements 4 are attached to a cover plate 21 with a Stütz¬ plate 22, on which also on Führungsdome 23, the continuous casting mold Ie 1 is added.
Die Lagerblöcke 18, 19, die jeweils zusammen den einteiligen Wandrahmen 20 bilden, sind auf einer Zwischenplatte 17 aufgestützt und befestigt. Der Wand¬ rahmen 20 weist Ausnehmungen 20a als Zugang zur Kokillenschmalseite 1a auf.The bearing blocks 18, 19, which together form the one-piece wall frame 20 are supported on an intermediate plate 17 and secured. The wall frame 20 has recesses 20a as access to the narrow side of the mold 1a.
Unterhalb der ersten Baugruppe 7, die die Deckplatte 21 und die Stützplatte 22 mit Führungsdornen 23 für die Stranggießkokille 1 umfasst, ist eine ortsfeste Baugruppe 24, bestehend aus einer Unterplatte 15, aus Stützwänden 16 und einer Zwischenplatte 17 gebildet, die auf einer am Stranggießgerüst ortsfesten, lösbaren Grundplatte 14 aufgestützt ist. Auf dieser ortsfesten Baugruppe 24, d.h. auf der Zwischenplatte 17, sind beidseitig Freiräume 25 für die Oszillati¬ onsbewegungen der blattförmigen Führungselemente 4 vorgesehen (vgl. die Fig. 2, 3 und 4).Below the first assembly 7, which comprises the cover plate 21 and the support plate 22 with guide pins 23 for the continuous casting mold 1, a stationary assembly 24, consisting of a lower plate 15, of support walls 16 and an intermediate plate 17 is formed, which is stationary on a Stranggießgerüst , releasable base plate 14 is supported.
