Description

Die Erfindung betrifft einen kippbaren Konverter, dessen Konvertergefäß mittels Auflagerkräfte aufnehmender Pratzenpaare auf einem um seinen Mantel angeordneten hohlen Tragkörper abgestützt ist, wobei die Pratzen eines Pratzenpaares beidseitig des Tragkörpers einander gegenüberliegen und wobei zwischen einer Pratze jedes Pratzenpaares und dem Tragkörper eine Kolben-Zylindereinheit vorgesehen ist, deren Kolben in Längsrichtung des Konvertergefäßes hydraulisch verstellbar ist.The invention relates to a tiltable converter, the converter vessel of which is supported by pairs of claws which support bearing forces on a hollow support body arranged around its jacket, the claws of a pair of claws lying opposite one another on both sides of the support body and a piston-cylinder unit being provided between a claw of each pair of claws and the support body whose piston is hydraulically adjustable in the longitudinal direction of the converter vessel.

Es ist bekannt, die beiderseits des Tragkörpers angeordneten Pratzen bei der Montage des Konverters durch Beilagen gegenüber dem Tragring spielfrei einzustellen, so daß das Konvertergefäß auch dann festgehalten wird, wenn der Konverter um 180° in den Kopfstand gekippt ist. Diese Bauweise, die sich insbesondere bei Großkonvertern bewährt hat, hat jedoch den Nachteil, daß es im Verlauf einer Konverterreise infolge ungleichmäßiger Wärmedehnungen - der Gefäßmantel dehnt sich in der Regel mehr als der Tragring trotz der Beilagen zu einer Spielbildung zwischen den Pratzen und dem Tragring kommen kann, wodurch Stöße verursacht werden, wenn der Konverter gekippt wird.It is known to adjust the claws arranged on both sides of the support body during the assembly of the converter by means of shims with respect to the support ring so that the converter vessel is held even when the converter is tilted by 180 ° into the headstand. This design, which has proven particularly useful for large converters, has the disadvantage, however, that in the course of a converter journey due to uneven thermal expansion - the vessel jacket generally stretches more than the support ring, despite the inserts, there is play between the claws and the support ring can cause shock if the converter is tilted.

Es sind verschiedene Maßnahmen vorgeschlagen worden, um dieses sich während einer Konverterreise einstellende Spiel zu vermeiden. Theoretisch kann dies dadurch geschehen (US-A-3 191 921), daß man die Pratzen mit Keilen versieht, deren schiefe Ebene jeweils auf einer korrespondierenden schiefen Ebene eines am Tragring abgestützten Keiles aufliegt, wobei die Neigung der schiefen Ebene entsprechend der theoretisch zu erwartenden radialen und axialen Dehnungen des Gefäßes gewählt wird. Diese Lösung hat jedoch insbesondere bei Großkonvertern, bei denen es auf die absolute Nullhaltung des Spieles ankommt, in der Praxis keinen Eingang gefunden, da der ideale Neigungswinkel der Keile lediglich theoretisch bestimmt werden konnte, das Konvertergefäß jedoch gegenüber dem Tragring nicht genau vorherbestimmbare Bewegungen infolge thermischer und mechanischer Einflüsse durchführt.Various measures have been proposed to avoid this game occurring during a converter trip. Theoretically, this can be done (US-A-3 191 921) by providing the claws with wedges, the inclined plane of which lies in each case on a corresponding inclined plane of a wedge supported on the support ring, the inclination of the inclined plane corresponding to that which is theoretically to be expected radial and axial expansion of the vessel is selected. However, this solution has not found its way into practice, particularly in the case of large converters where absolute zero play is important, since the ideal angle of inclination of the wedges could only be determined theoretically, but the converter vessel, due to thermal movements, could not be predicted precisely with respect to the support ring and mechanical influences.

Zur Ausschaltung des Spieles ist es weiters bekannt (österreichische Patentanmeldung A 8559/70), die an der Unterseite des Tragringes angeordneten Keile verschiebbar zu lagern, wobei als Verschiebeeinrichtung Federpakete vorgesehen sind. Ist dabei der Keilwinkel größer als der Reibungswinkel, so müssen die Federn so stark dimensioniert sein, daß sie in der Lage sind. das Konvertergefäß in der Konverterkopfstellung zu halten, wodurch in der 0°-Stellung, also wenn der Konverter aufrecht steht, große Zusatzkräfte auf das Konvertergefäß und auf den Tragring einwirken.To switch off the game, it is also known (Austrian patent application A 8559/70) to slidably mount the wedges arranged on the underside of the support ring, spring assemblies being provided as the displacement device. If the wedge angle is greater than the friction angle, the springs must be dimensioned so strongly that they are able to. to hold the converter vessel in the converter head position, so that in the 0 ° position, i.e. when the converter is upright, large additional forces act on the converter vessel and on the support ring.

Ein kippbarer Konverter der eingangs bezeichneten Art ist aus der US-A-3 400 922 bekannt. Bei diesem Konverter ist lediglich eine der beiden gegenüberliegenden Pratzen jedes Pratzenpaares mittels einer Kolben-Zylindereinheit gegen den Tragring abgestützt. Jede Kolben-Zylindereinheit ist mit einem außerhalb des Tragringes vorgesehenen, unter Druck stehenden Ausgleichsbehälter mittels Hydraulikleitungen verbunden. Dieser Ausgleichsbehälter muß ebenso wie die Hydraulikleitungen den vollen vom Konverter auf die Kolben-Zylindereinheiten übertragenen Druck aufnehmen können, worunter die Betriebssicherheit leidet.A tiltable converter of the type described in the opening paragraph is known from US-A-3,400,922. In this converter, only one of the two opposite claws of each pair of claws is supported against the support ring by means of a piston-cylinder unit. Each piston-cylinder unit is connected to a pressurized expansion tank provided outside the support ring by means of hydraulic lines. Like the hydraulic lines, this expansion tank must be able to absorb the full pressure transmitted from the converter to the piston-cylinder units, which reduces operational safety.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, einen Konverter, insbesondere einen Großkonverter zu schaffen, bei dem das zwischen den Tragpratzen und dem Tragring unvermeidliche Spiel beliebig groß sein kann, dieses Spiel jedoch keine Stöße beim Kippen des Konverters verursacht und wobei keinerlei Kräfte von der Konstruktion der Aufhängung des Konvertergefäßes im Tragring verursacht werden, die das Konvertergefäß oder den Tragring zusätzlich belasten.The invention aims to avoid these disadvantages and difficulties and has as its object to provide a converter, in particular a large converter, in which the inevitable play between the support claws and the support ring can be as large as desired, but this game does not cause any shocks when the converter is tilted and no forces are caused by the construction of the suspension of the converter vessel in the support ring, which additionally load the converter vessel or the support ring.

Diese Aufgabe der Erfindung wird dadurch gelöst, daß die Zylinder jeder Kolben-Zylindereinheit jeweils mit einem innerhalb des Tragkörpers vorgesehenen Ausgleichsbehälter, in dem das Hydraulikmedium unter Druck steht, mittels einer Hydraulikleitung verbunden sind, in die jeweils ein wahlweise in Funktion und außer Funktion schaltbares Rückschlagventil eingebaut ist, welches in Funktion das Einströmen von Hydraulikmittel nur in Richtung vom Ausgleichsbehälter in den Zylinder ermöglicht und außer Funktion die Hydraulikleitung in beide Richtungen freigibt. Die Verwirklichung dieser Merkmale an einem Konverter ermöglicht eine Dehnung des Konvertergefäßes in beliebiger Größe bei aufrechtstehendem Konverter und trotzdem die Vermeidung von Stößen beim Kippen des Konverters, u. zw. unabhängig von dem Druck innerhalb des Ausgleichsbehälters. Dieser Druck im Ausgleichsbehälter kann daher verhältnismäßig gering gehalten werden, so daß sich eine große Betriebssicherheit ergibt.This object of the invention is achieved in that the cylinders of each piston-cylinder unit are each connected to an expansion tank provided within the supporting body, in which the hydraulic medium is under pressure, by means of a hydraulic line, each of which has a check valve which can be optionally switched in and out of function is installed, which in function allows the inflow of hydraulic fluid only in the direction from the expansion tank into the cylinder and disables the hydraulic line in both directions. The realization of these features on a converter allows the converter vessel to be stretched to any size with the converter standing upright, and nevertheless prevents shocks when the converter is tilted, and the like. between regardless of the pressure inside the expansion tank. This pressure in the expansion tank can therefore be kept relatively low, so that there is great operational reliability.

Vorteilhaft ist zur Schaltung des Rückschlagventiles ein Impulsgeber vorgesehen, mit dem das Rückschlagventil bei aufrechtstehendem Konverter außer Funktion und bei Beginn des Kippens des Konverters in Funktion schaltbar ist.A pulse generator is advantageously provided for switching the check valve, with which the check valve can be switched off when the converter is in an upright position and when the converter begins to tilt.

Die Erfindung betrifft weiters einen kippbaren Konverter, dessen Konvertergefäß mittels Auflagerkräfte aufnehmender Pratzenpaare auf einem um seinen Mantel angeordneten hohlen Tragkörper abgestützt ist, wobei die Pratzen eines Pratzenpaares beidseitig des Tragkörpers einander gegenüberliegen und wobei zwischen beiden Pratzen jedes Pratzenpaares und dem Tragkörper Kolben-Zylindereinheiten vorgesehen sind, deren Kolben in Längsrichtung des Konvertergefäßes hydraulisch verstellbar sind. Ein Konverter dieser Art ist aus der DE-A-1 433498 bekannt. Bei diesem Konverter stützen sich beide gegenüberliegenden Pratzen der Pratzenpaare mittels Kolben-Zylindereinheiten gegen den Tragring ab. Bei dem bekannten Konverter handelt es sich um einen »Pendel-oder Schaukelkonverter«, d. h. um einen Konverter, der während des Blasvorganges in Pendel- bzw. Schaukelbewegungen versetzt wird. Der Tragring ist dabei gegenüber dem Fundament fixiert, und der Konverter wird mittels zwischen den Pratzen und dem Tragring vorgesehener Druckmittelzylinder bewegt. Diese müssen daher während des Konverterbetriebes die gesamte Last des Konverters aufnehmen.The invention further relates to a tiltable converter, the converter vessel of which is supported by means of support pairs of claws supported on a hollow support body arranged around its jacket, the claws of a pair of claws lying opposite one another on both sides of the support body, and piston-cylinder units being provided between the two claws of each pair of claws and the support body whose pistons are hydraulically adjustable in the longitudinal direction of the converter vessel. A converter of this type is known from DE-A- 1,433,498. In this converter, both opposite claws of the pairs of claws are supported against the support ring by means of piston-cylinder units. The known converter is a "pendulum or swing converter", that is to say a converter which is made to oscillate or swing during the blowing process. The support ring is fixed in relation to the foundation, and the converter is moved by means of pressure medium cylinders provided between the claws and the support ring. These must therefore take up the entire load of the converter during converter operation.

Auch hier besteht die Aufgabe, einen Konverter zu schaffen, bei dem das zwischen den Tragpratzen und dem Tragring unvermeidliche Spiel beliebig groß sein kann, dieses Spiel jedoch beim Kippen des Konverters keine Stöße verursacht, und bei dem weiters die Kolben-Zylindereinheiten nur kurzzeitig zur Lastaufnahme beansprucht werden.Here, too, there is the task of creating a converter in which the play which is inevitable between the support claws and the support ring can be as large as desired, but this play does not cause any shocks when the converter is tilted, and in which the piston-cylinder units only briefly take up the load be claimed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zylinder jeder Kolben-Zylindereinheit jeweils mit einem innerhalb des Tragkörpers vorgesehenen Ausgleichsbehälter, in dem das Hydraulikmedium unter Druck steht, mittels einer Hydraulikleitung verbunden sind, in die jeweils ein Drosselventil eingebaut ist.This object is achieved in that the cylinders of each piston-cylinder unit are each connected to an expansion tank provided within the support body, in which the hydraulic medium is under pressure, by means of a hydraulic line, in each of which a throttle valve is installed.

Gemäß dieser Ausführungsform sitzt der Konverter, u. zw. sowohl in aufrechter als auch in um 180° geschwenkter Lage, zwar auf den Kolben der an der jeweils oberen Seite des Tragringes befindlichen Kolben-Zylindereinheiten auf; die Kolben sind jedoch infolge der zwischen den Ausgleichsbehältern und der Kolben-Zylindereinheiten eingebauten Drosselventile in bis auf Anschlag zurückgedrückter Stellung, so daß die gesamte Hydraulikeinrichtung zur Lastaufnahme nicht beansprucht wird. Lediglich während der Zeit des Kippens und einer kurzen Zeitspanne danach, die das Hydraulikmittel benötigt, um durch die Drossel in den Ausgleichsbehälter zu strömen, wird die Hydraulikeinrichtung zur Gewichtsabstützung herangezogen. Auch bei dieser Ausführungsform ist der Ausgleichsbehälter stets und damit das Hydraulikmedium druckbelastet. Einen infolge des Konvertergewichtes hervorgerufenen Druck braucht er nicht aufnehmen zu können. Er trägt daher wesentlich zur Betriebssicherheit bei und kann entsprechend schwächer ausgebildet sein als die Kolben-Zylindereinheiten.According to this embodiment, the converter sits u. between both in an upright position and in a position pivoted through 180 °, namely on the piston of the piston-cylinder units located on the upper side of the support ring; however, the pistons are in the position pushed back as far as the stop due to the built-in throttle valves between the expansion tanks and the piston-cylinder units, so that the entire hydraulic device for load bearing is not stressed. The hydraulic device is used for weight support only during the time of the tipping and a short period afterwards, which the hydraulic medium needs to flow through the throttle into the expansion tank. In this embodiment too, the expansion tank is always pressurized and thus the hydraulic medium. It does not need to be able to absorb a pressure caused by the converter weight. It therefore contributes significantly to operational safety and can be designed to be correspondingly weaker than the piston-cylinder units.

Zweckmäßig ist in dem Ausgleichsbehälter ein federbeaufschlagter Verdrängungskolben vorgesehen.A spring-loaded displacement piston is expediently provided in the expansion tank.

Eine weitere bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß zusätzlich zu den in Längsrichtung des Konvertergefäßes vorgesehenen Kolben-Zylindereinheiten mindestens eine Pratze eines Pratzenpaares parallel zur Längsrichtung des Konvertergefäßes verlaufende Stützflächen aufweist, welche jeweils an am Tragkörper angeordneten Gegenstützflächen abgestützt sind, wobei mindestens eine Stütz-oder Gegenstützfläche von einem Kolben einer hydraulisch beaufschlagbaren, parallel zur Erstreckung des Tragkörpers angeordneten Kolben-Zylindereinheit gebildet ist.A further preferred embodiment is characterized in that, in addition to the piston-cylinder units provided in the longitudinal direction of the converter vessel, at least one claw of a pair of claws has support surfaces running parallel to the longitudinal direction of the converter vessel, which are each supported on counter support surfaces arranged on the support body, at least one support or Counter support surface is formed by a piston of a hydraulically actuated piston-cylinder unit arranged parallel to the extension of the support body.

Vorteilhaft sind dabei beide Stütz- oder Gegenstützflächen jeweils von einem Kolben einer Kolben-Zylindereinheit gebildet, wobei der Zylinder jeder Kolben-Zylindereinheit mit einem Ausgleichsbehälter über eine hydraulische Leitung verbunden ist, in die ein Drosselventil eingebaut ist.Both support or counter support surfaces are advantageously each formed by a piston of a piston-cylinder unit, the cylinder of each piston-cylinder unit being connected to an expansion tank via a hydraulic line, in which a throttle valve is installed.

Fig. 4 veranschaulicht die Anwendung der in den Fig. 1 bis 3 dargestellten Ausführungsform zur Abstützung der parallel zur Längsrichtung des Konvertergefäßes verlaufenden Stützflächen. Eine weitere Ausführungsform ist in den Fig. 5 bis 7 dargestellt, wobei Fig. 5 einen Konverter in zu Fig. 1 analoger Darstellung, Fig. 6 ein Detail der Fig. 5 in vergrößertem Maßstab und Fig. 7 ebenfalls die Anwendung der in den Fig. 5 und 6 dargestellten Ausführungsform für die parallel zur Längsrichtung des Konvertergefäßes verlaufenden Stützflächen zeigen.The invention is explained in more detail with reference to the drawing in several exemplary embodiments, with FIG. 1 a partially sectioned side view of a converter in the direction of the trunnion axis, FIG. 2 a view in the direction of arrow 11 of FIG. 1 and FIG. 3 a detail of FIG 1 show on an enlarged scale. FIG. 4 illustrates the use of the embodiment shown in FIGS. 1 to 3 for supporting the support surfaces running parallel to the longitudinal direction of the converter vessel. A further embodiment is shown in FIGS. 5 to 7, with FIG. 5 a converter in a representation analogous to FIG. 1, FIG. 6 a detail of FIG. 5 on an enlarged scale and FIG. 7 also the application of the in FIGS 5 and 6 show the embodiment shown for the support surfaces running parallel to the longitudinal direction of the converter vessel.

Mit 1 ist das Konvertergefäß bezeichnet, welches von einem Tragkörper 2, der als geschlossener Tragring ausgebildet ist, umgeben ist. Der Tragring 2 ist mittels zweier miteinander fiuchtender Tragzapfen 3 in nicht dargestellten Stützlagern kippbar gelagert.1 with the converter vessel is designated, which is surrounded by a support body 2, which is designed as a closed support ring. The support ring 2 is tiltably supported by two supporting pins 3 which are in alignment with one another in support bearings (not shown).

Das Konvertergefäß 1 ist mittels zweier Trag-Pratzenpaare 5, 6 und 7, 8 im Tragring 2 aufgehängt, die bei den Tragzapfen 3 angeordnet sind. In einer Ebene senkrecht zu den Tragzapfen 3 ist ein weiteres Pratzenpaar 9, 10 - das Kipp-Pratzenpaar - angeordnet. Diese drei Pratzenpaare sind zweckmäßig untereinander gleich gestaltet. Sie sind aus konstruktiven Gründen jeweils als Doppelpratzenpaar ausgebildet.The converter vessel 1 is suspended in the support ring 2 by means of two pairs of support claws 5, 6 and 7, 8, which are arranged in the support pin 3. A further pair of claws 9, 10 - the tilting claw pair - is arranged in a plane perpendicular to the support pins 3. These three pairs of claws are expediently designed to be identical to one another. For design reasons, they are each designed as a pair of double claws.

Diametral gegenüber dem Kipp-Pratzenpaar 9, 10 ist eine Führungseinrichtung 11 angeordnet, die in bekannter Weise lediglich zur Aufnahme von Seitenkräften ausgebildet ist und am Tragring 2 nicht aufliegt.A guide device 11 is arranged diametrically opposite the pair of tilting claws 9, 10, which is designed in a known manner only to absorb lateral forces and does not rest on the support ring 2.

Jede der Pratzen 5 bis 10 ist aus einem am Konvertergefäß angeschweißten Obergurt 12, einem am Konvertergefäß 1 angeschweißten Untergurt 13 und dazwischen liegenden, ebenfalls am Konvertergefäß angeschweißten Rippen 14 gebildet. Der Untergurt 13 der Pratzen weist jeweils zwei Kräfte, die in Längsrichtung 15 des Konvertergefäßes auftreten, übertragende Auflageflächen 16 auf und zwischen diesen Auflageflächen parallel zur Längsrichtung 15 des Konvertergefäßes verlaufende Stützflächen 17, die in Umfangsrichtung des Tragringes 2 gerichtete Kräfte auf die Gegenstützflächen 18, die am Tragring 2 befestigt sind, übertragen.Each of the claws 5 to 10 is formed from an upper flange 12 welded to the converter vessel, a lower flange 13 welded to the converter vessel 1, and ribs 14 located therebetween, also welded to the converter vessel. The lower flange 13 of the claws each has two forces which occur in the longitudinal direction 15 of the converter vessel, bearing surfaces 16 which transmit them, and between these bearing surfaces parallel to the longitudinal direction 15 of the converter vessel, support surfaces 17, the forces directed in the circumferential direction of the support ring 2 on the counter support surfaces 18 which are attached to the support ring 2, transferred.

Der Abstand 19 der einander gegenüberliegenden Auflageflächen 16 jeweils eines Pratzenpaares ist größer gewählt als die Höhe 20 des zwischen ihnen liegenden Tragringes 2. Zur Überbrückung des daraus resultierenden Spieles sind gemäß der Ausführungsform nach den Fig. 1 bis 4 an der Unterseite 21 des Tragringes Kolben-Zylindereinheiten 22 montiert, deren Achsen 23 etwa parallel zur Längsrichtung 15 des Konverters 1 angeordnet sind. Der Zylinder 24 jeder Kolben-Zylindereinheit 22 ist in den unterseitigen Gurt 25 des Tragringes 2 eingelassen und steht mittels einer Hydraulikleitung 26 mit einem innerhalb des Tragringes angeordneten Ausgleichsbehälter 27 in Verbindung. In der Hydraulikleitung ist ein mittels eines nicht dargestellten Impulsgebers wahlweise in Funktion und außer Funktion schaltbares Rückschlagventil 28 eingebaut, welches in Funktion das Einströmen von Hydraulikmittel nur in Richtung vom Ausgleichsbehälter 27 in den Zylinder 24 ermöglicht und außer Funktion die Hydraulikleitung 26 in beiden Richtungen freigibt. In jedem Ausgleichsbehälter 27 befindet sich ein federbeaufschlagter Verdrängungskolben 29, so daß das Hydraulikmittel stets in Richtung zur Kolben-Zylindereinheit 22 gedrängt wird.The distance 19 between the opposing bearing surfaces 16 of a pair of claws is chosen to be greater than the height 20 of the support ring 2 located between them. According to the embodiment according to FIGS. 1 to 4, to bridge the play resulting therefrom, piston rings Cylinder units 22 are mounted, the axes 23 of which are arranged approximately parallel to the longitudinal direction 15 of the converter 1. The cylinder 24 of each piston-cylinder unit 22 is embedded in the underside belt 25 of the support ring 2 and is connected by means of a hydraulic line 26 to an expansion tank 27 arranged within the support ring. In the hydraulic line, a check valve 28 which can be optionally switched into function and out of function is installed in the hydraulic line, which functionally allows the inflow of hydraulic medium only in the direction from the expansion tank 27 into the cylinder 24 and, in addition, releases the hydraulic line 26 in both directions. There is a spring-loaded displacement piston 29 in each expansion tank 27, so that the hydraulic medium is always pushed in the direction of the piston-cylinder unit 22.

Die Funktion der Einrichtung ist folgende: Der Konverter liegt zunächst, wenn er sich in aufrechter Stellung (0°-Position) befindet, nur mit seinen oberhalb des Tragringes 2 angeordneten Pratzen 5, 7, 9 am Tragring 2 auf. Durch die Verdrängungskolben 29 wird Hydraulikmittel in die Zylinder 24 eingepreßt, wodurch die Kolben 30 der Kolben-Zylindereinheiten 22 nach außen gedrückt werden, bis sie an den Auflageflächen 16 der an der Unterseite 21 des Tragringes 2 angeordneten Pratzen 6, 8, 10 anliegen. Ein Zurückdrängen der Kolben 30 wird durch die Rückschlagventile 28, wenn sie in Funktion geschaltet sind, verhindert. Da während einer Konverterreise das Konvertergefäß 1 immer wärmer wird, werden durch Wärmedehnungen des Gefäßes verursachte Vergrößerungen der Abstände 19 der einander gegenüberliegenden Auflageflächen 16 der Pratzenpaare 5, 6; 7, 8 und 9, 10 durch Nachströmen von Hydraulikmittel in die Zylinder 24 und das dadurch bewirkte Vorschieben der Kolben 30 ausgeglichen. Um Abstandsverkleinerungen der einander gegenüberliegenden Auflageflächen 16 der Pratzenpaare zuzulassen - eine solche findet beispielsweise im starken Ausmaß am Ende der Konverterreise bei Abkühlung des Konvertergefäßes statt - werden die Rückschlagventile 28 bei in 0°-Position befindlichem Konverter außer Funktion geschaltet. Zweckmäßig werden die Rückschlagventile 28 stets erst beim Kippen in Funktion geschaltet und nach Beendigung des Kippens (in 0°-Position des Konverters) außer Funktion geschaltet, so daß Schläge und Stöße während des Kippens nicht auftreten können. Da der Kippvorgang relativ kurz dauert, kann es während des Kippens nicht zum Auftreten von Zwangskräften zwischen den Pratzenpaaren 5,6; 7, 8 und 9, 10 und dem Tragring 2 kommen. Zwischen den Kippvorgängen können sich der Konverter und der Tragring beliebig verformen, da das Hydraulikmittel bei außer Funktion geschalteten Rückschlagventilen 28 in beiden Richtungen zu den und von den Zylindern 24 strömen kann.The function of the device is as follows: the converter, when it is in the upright position (0 ° position), only rests on the support ring 2 with its claws 5, 7, 9 arranged above the support ring 2. Hydraulic fluid is pressed into the cylinders 24 by the displacement pistons 29, whereby the pistons 30 of the piston-cylinder units 22 are pressed outwards until they rest on the contact surfaces 16 of the claws 6, 8, 10 arranged on the underside 21 of the support ring 2. The check valves 28 prevent the pistons 30 from being pushed back when they are in operation. Since the converter vessel 1 is getting warmer during a converter journey, increases in the distances 19 of the mutually opposite bearing surfaces 16 of the pairs of claws 5, 6; 7, 8 and 9, 10 compensated by hydraulic fluid flowing into the cylinders 24 and the consequent advancement of the pistons 30. In order to allow a reduction in the distance between the opposing support surfaces 16 of the pairs of claws - this occurs, for example, to a large extent at the end of the converter journey when the converter vessel cools down - the check valves 28 are deactivated when the converter is in the 0 ° position. The check valves 28 are expediently only switched into function when tilting and, after the tilting has ended (in the 0 ° position of the converter), switched off, so that shocks and impacts cannot occur during the tilting. Since the tipping process takes a relatively short time, it is not possible for the forces between the claw pairs 5,6; 7, 8 and 9, 10 and the support ring 2 come. Between the tilting processes, the converter and the support ring can deform as desired, since the hydraulic medium can flow to and from the cylinders 24 in both directions when the check valves 28 are switched off.

In Fig.4 ist die Anwendung des in Fig. 3 dargestellten Prinzips für die parallel zur Längsrichtung des Konvertergefäßes verlaufenden Stützflächen 17 veranschaulicht, wobei einander entsprechende Teile mit gleichen Bezugszeichen versehen sind. Für die in Längsrichtung des Konvertergefäßes verlaufenden Stützflächen ist die in Fig. 4 gezeigte Konstruktion nicht unbedingt erforderlich, da der Stützflächenabstand an jeder Pratze 5 bis 10 nur gering ist, so daß Dehnungen und Verformungen nur in wesentlich geringerem Maß auftreten als bei den Auflageflächen. Es ist möglich, auch die Führungseinrichtungen 11 wie in Fig. 4 dargestellt seitlich gegen den Tragring abzustützen.FIG. 4 illustrates the use of the principle shown in FIG. 3 for the support surfaces 17 running parallel to the longitudinal direction of the converter vessel, parts which correspond to one another being provided with the same reference symbols. The construction shown in FIG. 4 is not absolutely necessary for the support surfaces running in the longitudinal direction of the converter vessel, since the support surface spacing on each claw 5 to 10 is only small, so that expansion and deformation occur only to a much lesser extent than in the case of the support surfaces. It is possible to also support the guide devices 11 laterally against the support ring, as shown in FIG. 4.

Bei der in den Fig. 5 bis 7 dargestellten Ausführungsform sind bei jedem Pratzenpaar 5, 6; 7, 8 und 9, 10 Kolben-Zylindereinheiten 22 jeweils sowohl an der Ober- 31 als auch an der Unterseite 21 des Konvertertragringes 2 vorgesehen, wobei jeder Zylinder 24 der Kolben-Zylindereinheiten 22 über eine Hydraulikleitung 26 mit einem Ausgleichsbehälter 27 verbunden ist, in dem ein federbeaufschlagter Verdrängungskolben 29 eingebaut ist. In den Hydraulikkeitungen 26 ist jeweils ein Drosselventil 32 eingebaut.In the embodiment shown in FIGS. 5 to 7, each pair of claws 5, 6; 7, 8 and 9, 10 piston-cylinder units 22 are provided both on the upper 31 and on the lower side 21 of the converter support ring 2, each cylinder 24 of the piston-cylinder units 22 being connected to an expansion tank 27 via a hydraulic line 26, in which a spring-loaded displacement piston 29 is installed. A throttle valve 32 is installed in each of the hydraulic lines 26.

Die Funktion dieser Einrichtung ist folgende: Durch das Gewicht des Konverters wird bei aufrecht stehendem Konverter das Hydraulikmittel durch die Kolben 30 bei allen an der Oberseite 31 des Tragringes 2 angeordneten Kolben-Zylindereinheiten 22 jeweils in den Ausgleichsbehälter 27 gedrückt. Bei den an der Unterseite 21 des Tragringes angeordneten Kolben-Zylindereinheiten 22 wird jeweils der Kolben 30 infolge des federbeaufschlagten Verdrängungskolbens 29 im Ausgleichsbehälter 27 stets gegen die Auflageflächen 16 der unteren Tragpratzen 6, 8 und 10 gepreßt. Wird der Konverter gekippt, wirken die Drosselventile 32 der an der Unterseite 21 - die nun oberhalb des Tragringes 2 zu liegen kommt - des Tragringes angeordneten Kolben-Zylindereinheiten 22 zunächst zwar wie eine Blockierung der Hydraulikleitung 26, so daß sich das Konvertergefäß 1 gegenüber dem Tragring 2 im ersten Augenblick nicht bewegen kann, jedoch wird das Hydraulikmittel in weiterer Folge langsam in die Ausgleichsbehälter 27 gedrückt, so daß das Konvertergefäß 1 entsprechend dem Bewegungsspiel 33 der Kolben 30 gegenüber dem Tragring 2 ab nkt. Die beim Kippen des Konverters nach unten gelangenden Kolben-Zylindereinheiten 22 gleichen in dieser Zeit das Spiel zwischen Tragring 2 und Konvertergefäß 1 durch Absenken ihrer Kolben 30 (infolge der federbeaufschlagten Verdrängungskolben 29) aus. Es kann somit niemals ein Schlagen auftreten und auch austretende Verformungen des Konvertergefäßes sowie des Tragringes haben keinerlei zusätzliche Belastung für die Aufhängung zur Folge.The function of this device is as follows: the weight of the converter, when the converter is upright, presses the hydraulic medium through the pistons 30 in all the piston-cylinder units 22 arranged on the upper side 31 of the support ring 2 into the expansion tank 27. In the piston-cylinder units 22 arranged on the underside 21 of the support ring, the piston 30 is always pressed against the contact surfaces 16 of the lower support brackets 6, 8 and 10 as a result of the spring-loaded displacement piston 29 in the expansion tank 27. If the converter is tilted, the throttle valves 32 of the piston-cylinder units 22 arranged on the underside 21 - which now comes to lie above the support ring 2 - of the support ring initially act as a blockage of the hydraulic line 26, so that the converter vessel 1 is opposite the support ring 2 can not move in the first moment, but the hydraulic medium is subsequently pushed slowly into the expansion tank 27, so that the converter vessel 1 nkt corresponding to the play 33 of the pistons 30 with respect to the support ring 2. The piston-cylinder units 22 that come down when the converter is tilted compensate for the play between the support ring 2 and the converter vessel 1 by lowering their pistons 30 (as a result of the spring-loaded displacement pistons 29). There can thus never be a beating and escaping Ver Formations of the converter vessel and the support ring have no additional load on the suspension.

In Fig. ist die Anwendung der Einrichtung gemäß Fig. 6 für die parallel zur Längsrichtung 15 des Konvertergefäßes 1 verlaufenden Stützflächen 17 gezeigt, wobei wiederum einander entsprechende Teile mit gleichen Bezugszeichen versehen sind. Diese in Fig. gezeigte Einrichtung kann ebenfalls für die Führungseinrichtungen 11 Anwendung finden.6 shows the use of the device according to FIG. 6 for the support surfaces 17 running parallel to the longitudinal direction 15 of the converter vessel 1, parts which correspond to one another again being provided with the same reference symbols. This device shown in FIG. 1 can also be used for the guide devices 11.

Bei Großkonvertern kann es erforderlich sein, an jeder Auflagefläche der Pratzen 5 bis 10 mehrere Kolben-Zylindereinheiten 22 vorzusehen. Dabei ist es möglich, die nebeneinanderliegenden Kolben-Zylindereinheiten an demselben Ausgleichsbehälter anzuschließen, wobei es dann genügt, ein einziges Rückschlagventil bzw. eine einzige Drossel für die nebeneinanderliegenden Kolben-Zylindereinheiten vorzusehen. Es ist prinzipiell auch möglich, die Kolben-Zylindereinheit in die Pratzen einzubauen.In the case of large converters, it may be necessary to provide a plurality of piston-cylinder units 22 on each support surface of the claws 5 to 10. It is possible to connect the piston-cylinder units lying next to one another to the same expansion tank, it then being sufficient to provide a single check valve or a single throttle for the piston-cylinder units lying next to one another. In principle, it is also possible to install the piston-cylinder unit in the claws.
