Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Auswechseln der eine Strangführung bildenden Stützrollen einer Stranggießvorrichtung für Metalle, insbesondere für Stahl, die in Segmenten zusammengefasst sind.The invention relates to a method and an apparatus for replacing the support rollers of a continuous casting device for metals forming a strand guide, especially for steel, which are summarized in segments.
Die Stützrollen der Strangführung einer Gießmaschine sind hoch beansprucht und verschleißen in Abhängigkeit von den Einsatzbedingungen und den verwendeten Rollenwerkstoffen. Die Standzeit der Stützrollen ist deshalb von großer Bedeutung für die Verfügbarkeit der Gießmaschine und damit für die Gießleistung, d.h. die Produktionsmenge von Strangguss-Produkten.The support rollers of the strand guide of a casting machine are highly stressed and wear depending on the operating conditions and the used Role-based materials. The service life of the support rollers is therefore very important for the availability of the casting machine and thus for the casting performance, i.e. the Production volume of continuous cast products.
Die Strangführung ist in den meisten Fällen segmentiert aufgebaut. Dadurch werden einzelne Segmente in wenig transportable Abschnitte gegliedert, die schon austauschbar gestaltet worden sind (DE 198 11 651 A1). Die Segmente können durch einen Greifer aufgenommen werden und mittels einer kranähnlich an der Gießbühne geführten Maschine ab- und später wieder antransportiert werden (EP 0 029 798 B1). Eine ähnliche Segmentwechseleinrichtung für eine in Segmente unterteilte Stranggießanlage ist außerdem aus der DE 36 39 611 C1 bekannt. Alle diese Segmentwechseleinrichtungen sind aufwendig, schwer und teuer. Dabei ist jedoch der abschnittsweise Wechsel der Strangführung durch die zunehmende Flexibilisierung der Strangführung z.B. durch ihre hydraulische Energieversorgung und die hydraulischen Kolben-Zylinder-Einheiten immer aufwendiger und wartungsanfälliger.In most cases, the strand guide is segmented. This will individual segments divided into less transportable sections that already have been designed to be interchangeable (DE 198 11 651 A1). The segments can can be picked up by a gripper and by means of a crane-like on the Machine can be removed from the casting platform and later transported back (EP 0 029 798 B1). A similar segment changing device for one in segments divided continuous casting plant is also known from DE 36 39 611 C1. All these segment changing devices are complex, heavy and expensive. It is however, the section-by-section change of strand guidance due to increasing Flexibility of the strand guidance e.g. through their hydraulic energy supply and the hydraulic piston-cylinder units are more and more complex and require more maintenance.
Der Erfindung liegt die Aufgabe zugrunde, den Wechsel der Stützrollen in Stranggießanlagen ohne die aufwendige, teure Zerlegung eines ganzen Segmentes durchzuführen und dabei die entstehenden Transportgewichte zu berücksichtigen.The invention has for its object the change of support rollers in continuous casting plants without the complex, expensive disassembly of an entire segment and taking into account the resulting transport weights.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass nach Ausbau eines Segmentes mehrere, an einem Halterahmen drehgelagerte, zusammen eine Rollenkassette bildende Stützrollen, durch ein Hebezeug aus dem Segmentrahmen ausgebaut und eine instandgesetzte Rollenkassette wieder eingebaut und das Segment wieder in die Strangführungsposition zurückgebracht wird. Dadurch wird die teure Demontage ganzer Segmente umgangen und durch die Rollenkassetten werden kleinere, leichtere, transportablere Einheiten geschaffen, die auch leichter handhabbar sind.The object is achieved according to the invention in that after removal one segment several, rotatably mounted on a holding frame, together one Supporting rollers forming roller cassette, by means of a lifting device from the segment frame removed and a repaired roller cassette reinstalled and the segment is brought back into the strand guide position. Thereby the expensive dismantling of entire segments is avoided and by the roller cassettes smaller, lighter, more portable units are created that also are easier to handle.
Dabei ist es auch vorteilhaft, jeweils nach dem entstehenden Gesamtgewicht und nach den Ausbaumaßen, dass pro Segment ein erster Halterahmen mit drehgelagerten Stützrollen und ein zweiter, gegenüberliegender Halterahmen mit drehgelagerten Gegen-Stützrollen zusammen als eine Wechselkassette aus- oder eingebaut werden.It is also advantageous, depending on the total weight and according to the dimensions, that a first holding frame with rotating bearings per segment Support rollers and a second, opposite holding frame with pivoted Counter support rollers removed or installed together as an exchangeable cassette become.
Eine weitere Ausgestaltung besteht darin, dass eine obere Rollenkassette und eine untere Rollenkassette durch Abstandsmittel aufeinander abgestützt zusammen als Wechselkassette ausgebaut und eine solche Einheit nach Wartung wieder eingebaut wird.Another embodiment is that an upper roller cassette and a lower roller cassette supported by spacers together removed as a removable cassette and such a unit again after maintenance is installed.
Eine andere Aus- bzw. Einbaumethode ist als Weiterbildung dahingehend gestaltet, dass eine oder beide Rollenkassetten erst in Strangaderrichtung verschoben und dann durch das Hebezeug ausgebaut werden oder umgekehrt beim Einbauen verfahren wird.Another expansion or installation method is designed as a further training that one or both roller cassettes are only moved in the strand vein direction and then removed by the hoist or vice versa when installing is proceeded.
Die Vorrichtung zum Auswechseln der eine Strangführung bildenden Stützrollen einer Stranggießanlage für Metalle, insbesondere für Stahl, die in Segmenten zusammengefasst sind, löst die gestellte Aufgabe erfindungsgemäß dadurch, dass für die Festseite und die Losseite jeweils eine Rollenkassette, bestehend aus einer Anzahl von an einem Halterahmen drehgelagerten Stützrollen gebildet ist, wobei die Festseiten-Rollenkassette und die Losseiten-Rollenkassette jeweils mittels einer lösbaren Verbindung an dem Segmentrahmen anschließbar sind.The device for replacing the support rollers forming a strand guide a continuous caster for metals, especially for steel, which is combined in segments are, the object is achieved in that a roller cassette consisting of one for the fixed side and the loose side Number of support rollers rotatably mounted on a holding frame, wherein the fixed side roller cassette and the loose side roller cassette each by means of a detachable connection can be connected to the segment frame.
Eine Weiterbildung sieht vor, dass die Rollenkassette mehrteilig ist. Demzufolge können mehrere kleinere oder eine große Rollenkassette bei der Konstruktion von Anfang an gewählt werden.A further development provides that the roller cassette is in several parts. As a result, can use several smaller or one large roll cassette when designing Be chosen from the beginning.
Der Ausbauvorgang kann jeweils nach den Gewichts- und Abmessungsverhältnissen derart beeinflusst werden, dass die beiden Rollenkassetten mit Abstandsmitteln zusammen als Wechselkassette ausbaubar oder umgekehrt wieder einbaubar sind. Dadurch wird beim Wechsel der Stützrollen nur ein Arbeitsgang erforderlich.The removal process can vary according to the weight and size ratios are influenced in such a way that the two roller cassettes with spacers Can be removed together as a removable cassette or vice versa are. This means that only one operation is required when changing the support rollers.
Eine weitere Verbesserung ergibt sich dadurch, dass die Bewegungsrichtungen beim Ausbau oder Einbau der Rollenkassetten oder der Wechselkassetten vom Typ der Stranggießanlage abhängig festlegbar ist. Bei Senkrechtgießanlagen bietet sich an, die Rollenkassetten zumindest in Teilbereichen vertikal nach oben zu wechseln. Ein Wechsel ist auch dann möglich, wenn die Strangführung abschnittsweise seitlich aus der Betriebsposition heraus bewegt werden kann und die Rollenkassetten durch entsprechende Einrichtungen, wie z.B. eines Manipulators oder eines Krans entnommen oder später wieder eingesetzt werden. Der Einsatz solcher Rollenkassetten ist deshalb nicht auf einen speziellen Stranggießmaschinen-Typ beschränkt, sondern für alle Maschinen möglich. Another improvement results from the fact that the directions of movement when removing or installing the roll cassettes or the exchangeable cassettes from Type of continuous caster can be determined depending on. For vertical casting plants It is advisable to roll the roller cassettes vertically upwards, at least in some areas switch. A change is also possible if the strand guide in sections can be moved laterally out of the operating position and the roll cassettes by appropriate facilities, such as of a manipulator or removed from a crane or reinstalled later. The The use of such roller cassettes is therefore not a special type of continuous casting machine limited, but possible for all machines.
Weiter ist vorgesehen, dass der Segmentrahmen in seiner Grundform U-förmig ist und dass an der offen Seite ein starrer, etwa balkenförmiger Segmentrahmenteil mittels beidseitig angeordneter hydraulischer Kolben-Zylinder-Einheiten auf- oder zustellbar ist. Dadurch kann die richtige Öffnungsweite für das Wechseln der Rollenkassetten erreicht werden.It is further provided that the basic shape of the segment frame is U-shaped and that on the open side a rigid, approximately beam-shaped segment frame part by means of hydraulic piston-cylinder units arranged on both sides is deliverable. This allows the correct opening width for changing the Roller cassettes can be reached.
