Dabei ist der Kippantrieb während des Blasvorganges mittels eines Stellgerätes gegen das Fundament fixierbar.

DE 30 07 916 C2 zeigt eine Drehmomentenabstützung für einen reitenden Antrieb, insbesondere für Konverterantriebe, auf dessen anzutreibenden und ein Großrad drehfest tragenden Wellenzapfen das Getriebegehäuse gelagert ist, an dem mehrere das Großrad antreibende Untersetzungsgetriebe mit jeweiligen Antriebsmotoren angeflanscht sind und an dem über Gelenke auf gegenüberliegenden Seiten von der Drehachse des Wellenzapfens gleich beabstandete erste Parallelhebel angebracht sind, die über Gelenke mit zweiten gleichen, ortsfest angelenkten Parallelhebeln verbunden sind, mit mindestens einer die Parallelhebel, von denen einer schräg verläuft, verbindenden und mit einer Feder versehenen Koppel, wobei alle Gelenke sphärische Gelenklager aufweisen.

DE 30 07 916 C2 shows a torque support for a riding drive, in particular for converter drives, on the driven and a large gear rotatably supporting shaft journals, the gear housing is mounted on which several the large gear driving reduction gear with respective drive motors are flanged and on the joints on opposite Side of the axis of rotation of the journal equally spaced first parallel lever are mounted, which are connected via joints with the same second, fixedly articulated parallel levers, with at least one parallel lever, one of which obliquely extending, connecting and provided with a spring coupling, all joints spherical Have joint bearing.

Aus der DE 600 04 714 T2 ist ein Feststellorgan eines Elementes einer kinematischen Kette, wie zum Beispiel ein Element einer Zahnradübersetzung bekannt. Ein derartiges Feststellorgan ist beispielsweise an einer Pfanne eines Stahlwerkkonverters angebracht.From the DE 600 04 714 T2 is a locking member of an element of a kinematic chain, such as an element of a gear transmission known. Such a locking member is attached, for example, to a pan of a steelworks converter.

Es ist somit bekannt, dass die Konverter zum Entleeren durch ein fliegend gelagertes Getriebe gekippt werden. Dabei erfolgt die Abstützung des Kippmomentes permanent durch eine starre Momentenstütze, die an einem Ende an einem Fundament und an der anderen Seite an dem Getriebe befestigt ist. Konverter mit Unterbadspiegeldüsen sind im Betrieb, d.h. beim Zuführen von Sauerstoff, heftigen Schwingungen durch das bewegte Stahlbad ausgesetzt. Diese Anregung erfolgt breitbandig in alle Richtungen, also auch in Kipprichtung. Um das Getriebe von den sehr hohen Stößen zu entlasten wird in das Großrad ein Blockierarm eingerastet, der dafür sorgt, dass die Stöße nicht mehr über das Großrad und die Ritzel abgetragen werden, sondern direkt über das Getriebegehäuse in die Momentenstütze abgeleitet werden. Hierbei wirken hohe Kräfte auf das Fundament der Gießbühne und der Momentenstütze, die zu Schäden an der der Gießbühne und weiteren Anlagenteilen führt.It is thus known that the converters are dumped for emptying by a floating gearbox. In this case, the support of the tilting moment takes place permanently by a rigid moment support, which is fastened at one end to a foundation and at the other side to the transmission. Converters with subbubble nozzles are in operation, i. when supplying oxygen, subjected to violent vibrations through the moving steel bath. This excitation is broadband in all directions, including in tilt direction. To relieve the gear from the very high shocks a blocking arm is engaged in the large wheel, which ensures that the shocks are no longer removed via the large gear and the pinion, but are derived directly through the gear housing in the torque arm. Here, high forces act on the foundation of the casting platform and the torque arm, which leads to damage to the casting platform and other parts of the system.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem die o.g. Nachteile vermieden werden.The invention is therefore based on the object to provide a method by which the above-mentioned disadvantages are avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem Verfahren gemäß dem Oberbegriff von Anspruch 1 die Momentenstütze beim Kippvorgang des Konverters das Getriebe mit dem Fundament verbindet und beim Betrieb des Konverters vom Fundament oder vom Getriebe oder von beiden gelöst wird.This object is achieved in that in a method according to the preamble of claim 1, the torque arm during tilting of the converter connects the gearbox with the foundation and is released during operation of the converter from the foundation or from the transmission or both.

Weitere Ausgestaltungen des Bauteils ergeben sich aus den diesbezüglichen Unteransprüchen.Further embodiments of the component result from the relevant subclaims.

Der entscheidende Vorteil des erfindungsgemäßen Verfahrens liegt darin, dass der Konverter, wenn die Momentenstütze abgekoppelt ist, während des Betriebes freie Schwingungen ausführen kann. Die Amplitude der freien Schwingungen wird begrenzt bleiben. Durch das Zulassen der freien Drehbewegung werden die beim Betrieb eingebrachten Kräfte nicht mehr in das Fundament abgeleitet, sondern in Bewegungsenergie umgewandelt. Das Fundament und die Momentenstütze werden entlastet.The decisive advantage of the method according to the invention is that the converter, when the moment support is decoupled, can perform free oscillations during operation. The amplitude of the free vibrations will remain limited. By allowing the free rotation of the forces introduced during operation are no longer derived in the foundation, but converted into kinetic energy. The foundation and the momentum support are relieved.

In einer Weiterentwicklung ist vorgesehen, dass anstelle der Momentenstütze ein Stossdämpfer eingekuppelt wird. Der Konverter führt dann gedämpfte Schwingungen aus. Der eingekuppelte Stossdämpfer ist so ausgelegt, dass er die maximalen Amplituden des Konverters beim Betrieb begrenzt, allerdings ohne die Wirkung einer starren Momentenstütze zu erreichen.In a further development, it is provided that instead of the torque arm, a shock absorber is engaged. The converter then executes damped oscillations. The coupled shock absorber is designed to limit the maximum amplitudes of the converter during operation, but without the effect of a rigid torque support.

Ein Ausführungsbeispiel der Erfindung wird anhand einer sehr schematischen Zeichnung näher beschrieben.

zeigt in Seitenansicht einen Konverter mit einem Tragzapfen in einem Tragring.
An embodiment of the invention will be described with reference to a very schematic drawing.
Fig. 1
shows in side view a converter with a support pin in a support ring.

In der einzigen Figur ist in Seitenansicht ein Konverter 1 mit Tragzapfen 2 dargestellt. Die auf gegenüberliegenden Seiten des Konverters 1 angebrachten Tragzapfen 2 sind in einem Tragring 3 gelagert. Hierdurch wird ein Kippen des Konverters 1 um seine Horizontalachse ermöglicht.In the single figure, a converter 1 with trunnions 2 is shown in side view. The attached on opposite sides of the converter 1 Trunnions 2 are mounted in a support ring 3. This allows tilting of the converter 1 about its horizontal axis.

Auf dem Tragzapfen 2 ist fliegend ein Getriebe 4 zum Kippen des Konverters 1 angeordnet. Das Getriebe 4 wird zur Abstützung des Kippmomentes über eine Momentenstütze 5 mit einem Fundament 6 verbunden. Das Fundament 6 ist beispielsweise die Gießbühne. Während eines Kippvorganges verbindet die Momentenstütze 5 das Getriebe 4 mit dem Fundament 6, um das Kippmoment abzustützen.On the trunnion 2 a gear 4 is arranged to tilt the converter 1 flying. The transmission 4 is connected to support the tilting moment via a torque support 5 with a foundation 6. The foundation 6 is, for example, the casting platform. During a tilting operation, the moment support 5 connects the transmission 4 to the foundation 6 in order to support the overturning moment.

Während des Betriebes des Konverters 1, d.h. in der Zeit, in dem Sauerstoff in den Konverter eingebracht wird, wird die Momentenstütze 5 entweder von dem Getriebe 4 oder dem Fundament 6 oder von beiden abgekoppelt und der Konverter 1 kann frei schwingen. Alternativ kann parallel zur Momentenstütze 5 ein Stossdämpfer in der Zeit des Betriebes eingebaut werden, durch den die Schwingungen des Konverters gedämpft werden.During operation of the converter 1, ie in the time in which oxygen is introduced into the converter, the torque arm 5 is decoupled from either the transmission 4 or the foundation 6 or both, and the converter 1 is free to oscillate. Alternatively, parallel to the torque support 5, a shock absorber can be installed in the time of operation, by which the vibrations of the converter are damped.
