Definitions
- the invention relates to a method and a device for exchanging the support rollers forming a strand guide of a continuous casting apparatus for metals, in particular for steel, which are combined into segments.
- the support rollers of the strand guide of a casting machine are highly stressed and wear depending on the conditions of use and the rolling materials used.
- the service life of the support rollers is therefore of great importance for the availability of the casting machine and thus for the casting performance, i. the production volume of continuous casting products.
- the strand guide is segmented in most cases. As a result, individual segments are divided into less transportable sections, which have already been made interchangeable (DE 198 11 651 A1). The segments can be picked up by a gripper and removed by means of a machine similar to a crane on the casting platform and subsequently transported back again (EP 0 029 798 B1). A similar segment exchange device for a segmented continuous casting is also known from DE 36 39 611 C1. All of these segment change devices are complex, heavy and expensive. However, the section-wise change of the strand guide by the increasing flexibility of the strand guide, for example, by their hydraulic power supply and the hydraulic piston-cylinder units increasingly complex and maintenance-prone.
- the document DE 1 458 032 A discloses a support roller arrangement on a continuous casting stand, in which the individual support rollers are taken together in the form of roll baskets.
- the roller bodies are detachably mounted with each other and on a support frame and mutually exchangeable. Damaged reel baskets can be replaced with intact reel bodies.
- the invention has the object, further to form a method and apparatus for replacing roll cassettes in a strand guide to the effect that such a change is possible in only one operation.
- each segment an upper and a lower roll cassette on spacer means are mutually supported and together form an exchangeable cassette, which can be expanded as a whole and vice versa can be re-installed in the same segment. In this way, only one operation is advantageously required when changing the support rollers or when changing from multiple roll cassettes.
- Another removal or installation method is designed as training to the effect that one or both roller cassettes moved only in the stranding direction and then removed by the hoist or vice versa is moved during installation.
- the device for exchanging the support rollers forming a strand guide of a continuous casting plant for metals, in particular for steel, which are combined into segments, achieves the stated object according to the invention in that the two roll cassettes with spacers together as a removable cassette with the help of a Hebezugs expandable or vice versa are re-installable. As a result, only one operation is required when changing the support rollers.
- a further improvement results from the fact that the directions of movement when removing or installing the roller cassettes or exchangeable cassettes depending on the type of continuous casting is determined.
- a change is also possible if the strand guide sections laterally out of the operating position can be moved out and the roll cassettes removed by appropriate means, such as a manipulator or a crane or used later.
- the use of such roll cassettes is therefore not limited to a special continuous casting machine type, but for all machines possible.
- segment frame is U-shaped in its basic form and that on the open side a rigid, approximately bar-shaped segment frame part by means of both sides arranged hydraulic piston-cylinder units or can be raised. As a result, the correct opening width for changing the roll cassettes can be achieved.

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 a device for exchanging the support rollers forming a strand guide of a continuous casting apparatus for metals, in particular for steel, which are combined into 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 conditions of use and the rolling materials used. The service life of the support rollers is therefore of great importance for the availability of the casting machine and thus for the casting performance, i. the production volume of continuous casting 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.The strand guide is segmented in most cases. As a result, individual segments are divided into less transportable sections, which have already been made interchangeable (DE 198 11 651 A1). The segments can be picked up by a gripper and removed by means of a machine similar to a crane on the casting platform and subsequently transported back again (EP 0 029 798 B1). A similar segment exchange device for a segmented continuous casting is also known from DE 36 39 611 C1. All of these segment change devices are complex, heavy and expensive. However, the section-wise change of the strand guide by the increasing flexibility of the strand guide, for example, by their hydraulic power supply and the hydraulic piston-cylinder units increasingly complex and maintenance-prone.
Die Druckschrift DE 1 458 032 A offenbart eine Stützrollenanordnung an einem Stranggussgerüst, bei der die einzelnen Stützrollen in Form von Rollenkörben zusammen gefasst sind. Die Rollenkörper sind untereinander und auf einem Trägergerüst lösbar montiert und gegenseitig austauschbar. Beschädigte Rollenkörbe können gegen intakte Rollenkörper ausgetauscht werden.The document DE 1 458 032 A discloses a support roller arrangement on a continuous casting stand, in which the individual support rollers are taken together in the form of roll baskets. The roller bodies are detachably mounted with each other and on a support frame and mutually exchangeable. Damaged reel baskets can be replaced with intact reel bodies.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Auswechseln von Rollenkassetten bei einer Strangführung dahingehend weiter zu bilden, dass ein solcher Wechsel jeweils in nur einem Arbeitsgang möglich wird.Based on this prior art, the invention has the object, further to form a method and apparatus for replacing roll cassettes in a strand guide to the effect that such a change is possible in only one operation.
Diese Aufgabe wird durch das in Patentanspruch 1 beanspruchte Verfahren gelöst. Dieses Verfahren ist dadurch gekennzeichnet, dass pro Segment jeweils eine obere und eine untere Rollenkassette auf Abstandsmitteln aufeinander abgestützt sind und zusammen eine Wechselkassette bilden, welche als Ganzes ausgebaut und umgekehrt wieder in dasselbe Segment eingebaut werden kann. Auf diese Weise wird vorteilhafterweise beim Wechsel der Stützrollen bzw. beim Wechsel von mehreren Rollenkassetten nur ein Arbeitsgang benötigt.This object is achieved by the method claimed in claim 1. This method is characterized in that each segment an upper and a lower roll cassette on spacer means are mutually supported and together form an exchangeable cassette, which can be expanded as a whole and vice versa can be re-installed in the same segment. In this way, only one operation is advantageously required when changing the support rollers or when changing from multiple roll cassettes.
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 removal or installation method is designed as training to the effect that one or both roller cassettes moved only in the stranding direction and then removed by the hoist or vice versa is moved during installation.
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 die beiden Rollenkassetten mit Abstandsmitteln zusammen als Wechselkassette mit Hilfe eines Hebezugs ausbaubar oder umgekehrt wieder einbaubar sind. Dadurch wird beim Wechsel der Stützrollen nur ein Arbeitsgang erforderlich.The device for exchanging the support rollers forming a strand guide of a continuous casting plant for metals, in particular for steel, which are combined into segments, achieves the stated object according to the invention in that the two roll cassettes with spacers together as a removable cassette with the help of a Hebezugs expandable or vice versa are re-installable. As a result, 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.A further improvement results from the fact that the directions of movement when removing or installing the roller cassettes or exchangeable cassettes depending on the type of continuous casting is determined. In vertical casting plants, it is advisable to change the roll cassettes vertically upwards, at least in some areas. A change is also possible if the strand guide sections laterally out of the operating position can be moved out and the roll cassettes removed by appropriate means, such as a manipulator or a crane or used later. The use of such roll cassettes is therefore not limited to a special continuous casting machine type, but for all machines possible.
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 segment frame is U-shaped in its basic form and that on the open side a rigid, approximately bar-shaped segment frame part by means of both sides arranged hydraulic piston-cylinder units or can be raised. As a result, the correct opening width for changing the roll cassettes can be achieved.
In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt und wird nachfolgend näher erläutert.In the drawing, an embodiment is shown schematically and will be explained in more detail below.
Die einzige Figur der Zeichnung stellt eine Vorderansicht gegen den Segmentrahmen einer Stranggießanlage dar.The sole figure of the drawing represents a front view against the segment frame of a continuous casting plant.
Das Verfahren zum Auswechseln der eine Strangführung bildenden Stützrollen 1 innerhalb von Segmenten 2 einer Stranggießvorrichtung für Metalle, insbesondere für Stahl, wird in solchen Schritten ausgeführt, dass nach Ausbau eines Segmentes 2 und nach Transport in die Segmentwerkstatt , mehrere, an einem Halterahmen 3 drehgelagerte, zusammen eine Rollenkassette 4 bildende Stützrollen 1, durch ein Hebezeug 7 aus dem Segmentrahmen 2a ausgebaut und eine instandgesetzte Rollenkassette 4 nach deren Wartung wieder eingebaut und das Segment 2 wieder in die Strangführungsposition zurückgebracht wird. Dabei kann auch pro Segment 2 ein erster Halterahmen 3 mit drehgelagerten Stützrollen 1 und ein zweiter, gegenüberliegender Halterahmen 3 mit drehgelagerten Gegen-Stützrollen 1a zusammen als eine Wechselkassette 5 aus- oder eingebaut werden. Als ein alternativer Schritt ist dann möglich, dass eine obere Rollenkassette 4 und eine untere Rollenkassette 4 durch Abstandsmittel 6, z.B. durch eine Metall- oder Holzeinlage, aufeinander abgestützt zusammen als Wechselkassette 5 ausgebaut und eine instandgesetzte Einheit nach Wartung wieder eingebaut wird. Je nach dem Typ der Stranggießanlage, ob Senkrecht-, Senkrecht-Abbiege- oder Bogenanlage kann auch eine oder beide Rollenkassetten 4 in Strangaderrichtung verschoben werden und dann durch das Hebezeug 7 ausgebaut werden oder dass in umgekehrter Reihenfolge beim Einbauen verfahren wird.The process for replacing the support rollers 1 forming a strand guide within
Die Vorrichtung zum Auswechseln der eine Strangführung bildenden Stützrollen 1 einer Stranggießanlage für Metalle, insbesondere für Stahl, die in Segmenten 2 zusammengefasst sind, sieht für die Festseite 8 und für die Losseite 9 jeweils eine Rollenkassette 4 vor, bestehend aus einer Anzahl von an einem Halterahmen 3 drehgelagerten Stützrollen 1, wobei die Festseiten-Rollenkassette 10 und die Losseiten- Rollenkassette 11 jeweils mittels einer lösbaren Verbindung 12 an dem Segmentrahmen 2a angeklemmt wird.The device for exchanging the strand guide forming a
