Horizontalabstützung für einen kippbaren Konverter und Verfahren zum Umbau eines kippbaren Konverters.Horizontal support for a tiltable converter and method for converting a tiltable converter.

Technisches GebietTechnical area

Die Erfindung betrifft einen kippbaren Konverter, umfassend ein Konvertergefäß mit einer Konverterachse, einen das Konvertergefäß mit Abstand umfassenden Tragring mit zwei diametral gegenüberliegenden Tragzapfen, welche jeweils auf einer Festlagerseite beziehungsweise auf einer Loslagerseite des Tragrings angeordnet sind und ein Aufhängungssystem zur Abstützung des Konvertergefäßes am Tragring. Das Aufhängungssystem umfasst zumindest zwei parallel zu einer vom Tragring gebildeten Tragringebene ausgerichtete horizontale Verbindungselemente, die jeweils mit ihren gegenüberliegenden Enden am Konvertergefäß beziehungsweise am Tragring gelenkig angreifen.The invention relates to a tiltable converter, comprising a converter vessel with a converter axis, a converter vessel at a distance comprehensive support ring with two diametrically opposed trunnions, which are each arranged on a fixed bearing side or on a floating bearing side of the support ring and a suspension system for supporting the converter vessel on the support ring. The suspension system comprises at least two horizontal connecting elements aligned parallel to a support ring plane formed by the support ring, which each engage in an articulated manner with their opposite ends on the converter vessel or on the support ring.

Ein weiterer Gegenstand der Erfindung ist ein Verfahren zum Umbau eines kippbaren Konverters.Another object of the invention is a method for converting a tiltable converter.

Stand der TechnikState of the art

Aus dem Stand der Technik ist eine Reihe von Aufhängungssystemen zur Abstützung eines Konvertergefäßes bekannt. Wesentliche Ziele dieser Aufhängungssysteme sind ein geringer Platzbedarf der Aufhängungssysteme unter gleichzeitigem Einsatz möglichst großer Konvertergefäße, eine optimale Abstützung des Konverters an den Aufhängungssystemen, die Aufnahme von Konverterverformungen durch die Aufhängungssysteme sowie ein geringer Wartungsaufwand und eine hohe Lebensdauer der Aufhängungssysteme.From the prior art, a number of suspension systems for supporting a converter vessel is known. The essential objectives of these suspension systems are a small space requirement of the suspension systems while using the largest possible converter vessels, an optimal support of the converter to the suspension systems, the inclusion of converter deformations by the suspension systems and low maintenance and a high durability of the suspension systems.

Beispielsweise offenbaren die DE 4327640 , die US 6228320 , die WO 2011098318 und die WO 2012025262 jeweils einen kippbaren Konverter mit einem Konvertergefäß und einem Tragring, wobei das Konvertergefäß mittels mehrerer Pendelstäbe am Tragring abgestützt ist. Die Anlenkungen der Pendelstäbe am Tragring beziehungsweise am Konvertergefäß sind in den angegebenen Dokumenten teilweise unterschiedlich, insbesondere gelenkig und/oder allseits gelenkig, ausgeführt. In der WO 2011098318 und der WO 2012025262 sind zusätzlich Stabilisierungsvorrichtungen zur Limitierung einer Bewegung des Konvertergefäßes relativ zum Tragring vorgesehen.For example, the DE 4327640 , the US 6228320 , the WO 2011098318 and the WO 2012025262 each one tiltable Converter with a converter vessel and a support ring, wherein the converter vessel is supported by means of several pendulum rods on the support ring. The articulations of the pendulum rods on the support ring or on the converter vessel are in the specified documents partially different, especially articulated and / or articulated on all sides, running. In the WO 2011098318 and the WO 2012025262 In addition, stabilizing devices are provided for limiting movement of the converter vessel relative to the support ring.

Nachteilig bei diesen aus dem Stand der Technik bekannten Ausführungsformen ist, dass die Pendelstäbe und deren Anlenkungen beziehungsweise Lager, insbesondere bei gekipptem Konvertergefäß während einer Chargierung oder während eines Abstichs, hohen Belastungen ausgesetzt sind, und daher entsprechend groß und robust ausgelegt sein müssen. Dies führt zu einem hohen Platzbedarf und zu hohen Kosten der entsprechenden Aufhängungssysteme. Zusätzlich führt diese hohe Belastung zu einer Beeinträchtigung der Lebensdauer der Aufhängungssysteme. Ein weiterer Nachteil, der sich durch die robuste Auslegung der Pendelstäbe beziehungsweise deren Lager ergibt, ist, dass der für das Konvertergefäß zur Verfügung stehende Platz begrenzt ist beziehungsweise der erzielbare Durchmesser des Konvertergefäßes limitiert ist. Teilweise sind Stabilisierungsvorrichtungen notwendig, die zusätzlich Kosten und Wartungsaufwand verursachen.A disadvantage of these known from the prior art embodiments is that the pendulum rods and their links or bearings, in particular tilted converter vessel during charging or during a tapping, are exposed to high loads, and therefore must be designed to be large and robust. This leads to a high space requirement and high costs of the corresponding suspension systems. In addition, this high load leads to a deterioration of the life of the suspension systems. Another disadvantage resulting from the robust design of the pendulum rods or their bearings is that the space available for the converter vessel is limited or the achievable diameter of the converter vessel is limited. Partial stabilization devices are necessary, which cause additional costs and maintenance.

Eine weitere Ausführungsform eines kippbaren Konverters ist in der WO 2008092488 offenbart. In dieser Ausführungsform wird ein kippbarer Konverter mit einer Vielzahl von Verbindungselementen am Tragring abgestützt, wobei die Verbindungselemente als Lamellenpakete und/oder als Pendelstäbe ausgeführt sind.Another embodiment of a tiltable converter is in WO 2008092488 disclosed. In this embodiment, a tiltable converter with a plurality of connecting elements is supported on the support ring, wherein the connecting elements are designed as disk packs and / or as pendulum rods.

Die unterschiedlich ausgeführten Verbindungselemente führen zu einem erhöhten Aufwand an Lagerlogistik und verursachen daher hohe Lagerhaltungskosten beziehungsweise Logistikkosten.The differently designed fasteners lead to an increased amount of warehouse logistics and cause therefore high storage costs or logistics costs.

Die WO 2011157498 offenbart einen kippbaren Konverter, der mittels Lamellen zur Aufnahme von vertikalen Kräften am Tragring abgestützt ist. Horizontale Kräfte werden mittels Konsolen beziehungsweise Links vom Konvertergefäß auf den Tragring übertragen.The WO 2011157498 discloses a tiltable converter which is supported by means of lamellae for receiving vertical forces on the support ring. Horizontal forces are transmitted by means of brackets or links from the converter vessel to the support ring.

In der DE 1508156 ist ein kippbarer Konverter mit Tragzapfen offenbart, wobei sich der Konverter mit Pratzen auf Schilde abstützt, die an den Tragzapfen angebracht sind.In the DE 1508156 discloses a tiltable converter with trunnions, wherein the converter is supported with claws on shields, which are attached to the support pin.

Der Einsatz von Lamellenpaketen, Lamellen oder Pratzen als Verbindungselemente ist generell nachteilig, da derartige Systeme üblicherweise ein großes Spiel aufweisen. Insbesondere ist der Einsatz von Pratzen problematisch, da Kontaktflächen der Pratzen nur schwierig auszurichten sind. Durch eine ungenaue Ausrichtung solcher Pratzen entstehen hohe Flächenpressungen, welche die Lebensdauer derartiger Aufhängungssysteme negativ beeinflussen und den Wartungsaufwand erhöhen.The use of disk packs, lamellae or lugs as connecting elements is generally disadvantageous, since such systems usually have a great deal of play. In particular, the use of claws is problematic because contact surfaces of the claws are difficult to align. Due to an inaccurate alignment of such claws arise high surface pressures, which adversely affect the life of such suspension systems and increase maintenance.

Technische LösungTechnical solution

Diese Aufgabe wird erfindungsgemäß durch einen kippbarer Konverter, umfassend ein Konvertergefäß mit einer Konverterachse, einen das Konvertergefäß mit Abstand umfassenden Tragring mit zwei diametral gegenüberliegenden Tragzapfen, welche jeweils auf einer Festlagerseite beziehungsweise auf einer Loslagerseite des Tragrings angeordnet sind, ein Aufhängungssystem zur Abstützung des Konvertergefäßes am Tragring, umfassend parallel zu einer vom Tragring gebildeten Tragringebene ausgerichtete horizontale Verbindungselemente, die jeweils mit ihren gegenüberliegenden Enden am Konvertergefäß beziehungsweise am Tragring gelenkig angreifen, und die horizontalen Verbindungselemente mittels in Lagern der horizontalen Verbindungselemente gelagerten Anlenkelementen beweglich an am Konvertergefäß befestigten Konverterstützlaschen und an am Tragring befestigten Tragringstützlaschen angelenkt sind, wobei im Grundriss zumindest ein horizontales Verbindungselement im Bereich der Tragzapfen, mit seiner Längsachse in seinem Konverteranlenkpunkt normal zu einem von der Konverterachse ausgehenden und seinen Konverteranlenkpunkt durchstoßenden Strahl ausgerichtet ist,
mit einer von den Tragzapfen gebildeten Kippachse, wobei die Bereiche der Tragzapfen durch jeweils zwei im Grundriss des Konvertergefäßes symmetrisch zur Kippachse liegende und von der Konverterachse ausgehende Geraden, welche einen Winkel von bis zu 60°, bevorzugt einen Winkel von bis zu 55°, einschließen, festgelegt sind, gelöst. Erfindungsgemäß sind im Bereich zumindest eines der beiden Tragzapfen zumindest zwei horizontale Verbindungselemente angeordnet, wobei alle im Bereich der Tragzapfen angeordneten horizontalen Verbindungselemente in der selben Ebene liegen und wobei diese Ebene bei aufrechter Position des Konvertergefäßes, wenn die Konverterachse parallel zum Lot ausgerichtet ist, unterhalb oder oberhalb der Tragringebene liegt.This object is achieved by a tiltable converter comprising a converter vessel with a converter axis, a supporting ring comprising the converter vessel at a distance with two diametrically opposed trunnions, which are each arranged on a fixed bearing side or on a floating bearing side of the support ring, a suspension system for supporting the converter vessel on the support ring, comprising parallel to a support ring formed by the support ring level aligned horizontal connecting elements, each with its opposite ends on the converter vessel or engage articulated on the support ring, and the horizontal connecting elements are articulated by means mounted in bearings of the horizontal connecting elements articulated to the converter vessel converter support brackets and attached to the support ring Tragringstützlaschen, wherein in plan at least one horizontal connecting element in the trunnions, with its longitudinal axis in its Konverteranlenkpunkt is oriented normal to a beam originating from the converter axis and piercing its converter connecting point,
with a tilting axis formed by the support pins, wherein the regions of the support pins by two in the plan view of the converter vessel symmetrical to the tilting axis and emanating from the converter axis straight lines, which form an angle of up to 60 °, preferably an angle of up to 55 ° , are fixed. According to the invention at least two horizontal connecting elements are arranged in the region of at least one of the two trunnions, wherein all horizontal connecting elements arranged in the region of the trunnions lie in the same plane and wherein this plane is in an upright position of the converter vessel when the converter axis is aligned parallel to the perpendicular, below or lies above the support ring level.

Unter Konverterachse ist die Rotationsachse des Konvertergefäßes zu verstehen.The converter axis is to be understood as the axis of rotation of the converter vessel.

Erfindungsgemäß umfasst der kippbare Konverter einen das Konvertergefäß mit Abstand umfassenden Tragring mit zwei diametral gegenüberliegenden Tragzapfen, welche jeweils auf einer Festlagerseite beziehungsweise auf einer Loslagerseite des Tragrings angeordnet sind.According to the invention, the tiltable converter comprises a converter ring with spacing comprehensive support ring with two diametrically opposed trunnions, each on one Fixed bearing side or on a floating bearing side of the support ring are arranged.

Die Festlagerseite des Tragrings ist jene Seite des Tragrings, an der der Tragzapfen mittels eines Festlagers gelagert ist. Die Loslagerseite des Tragrings ist jene Seite des Tragrings, an der der Tragzapfen mittels eines Loslagers gelagert ist.The fixed bearing side of the support ring is that side of the support ring on which the support pin is mounted by means of a fixed bearing. The floating bearing side of the support ring is that side of the support ring on which the support pin is mounted by means of a movable bearing.

Unter Festlager ist ein Lager zu verstehen, welches axiale und radiale Kräfte aufnehmen kann. Ein Loslager kann nur radiale Kräfte aufnehmen.A fixed bearing is to be understood as a bearing which can absorb axial and radial forces. A floating bearing can only absorb radial forces.

Weiter umfasst der kippbare Konverter parallel zu einer vom Tragring gebildeten Tragringebene ausgerichtete horizontale Verbindungselemente, die jeweils mit ihren gegenüberliegenden Enden am Konvertergefäß beziehungsweise am Tragring gelenkig angreifen.Furthermore, the tiltable converter comprises parallel to a supporting ring formed by the support ring ring oriented horizontal connecting elements, which engage in each case with their opposite ends on the converter vessel or on the support ring articulated.

Die Tragringebene steht normal zur Rotationsachse des Tragrings.The support ring plane is normal to the axis of rotation of the support ring.

Die horizontalen Verbindungselemente haben vorzugsweise eine längliche Form mit einer geraden Längsachse.The horizontal connecting elements preferably have an elongated shape with a straight longitudinal axis.

Unter parallel ist in diesem Zusammenhang entweder eine exakte Parallelität der Längsachsen der horizontalen Verbindungselemente in Bezug auf die Tragringebene oder eine im Stand der Technik auf diesem Gebiet übliche Abweichung von der exakten Parallelität in Bezug auf die Tragringebene, beispielsweise durch Spielräume und/oder Fertigungsungenauigkeiten und/oder elastischen Deformationen von Bauteilen, zu verstehen.Under parallel in this context is either an exact parallelism of the longitudinal axes of the horizontal connecting elements with respect to the support ring level or a standard in the art in this field deviation from the exact parallelism with respect to the support ring plane, for example, by margins and / or manufacturing inaccuracies and / or elastic deformations of components, to understand.

Die horizontalen Verbindungselemente greifen jeweils mit ihren gegenüberliegenden Enden am Konvertergefäß beziehungsweise am Tragring gelenkig an, womit eine Kraftübertragung zwischen den horizontalen Verbindungselementen und dem Konvertergefäß beziehungsweise dem Tragring ermöglicht wird. Damit wird eine zwängungsfreie Abstützung des Konvertergefäßes am Tragring sichergestellt.The horizontal connecting elements each engage with their opposite ends on the converter vessel or on the support ring articulated, whereby a power transmission between the horizontal connecting elements and the converter vessel or the support ring is made possible. This ensures a constraint-free support of the converter vessel on the support ring.

Die horizontalen Verbindungselemente greifen jeweils nur mit ihren gegenüberliegenden Enden am Konvertergefäß beziehungsweise am Tragring an. Unter Enden sind Endbereiche, insbesondere die horizontalen Verbindungselemente in deren Längserstreckung entlang deren Längsachsen begrenzende Bereiche zu verstehen. Vorzugsweise ist an diesen Endbereichen zumindest jeweils eine Lasche mit einem Lager angeordnet.The horizontal connecting elements engage only with their opposite ends on the converter vessel or on the support ring. Endings are to be understood as meaning end regions, in particular the horizontal connecting elements in their longitudinal extent along the longitudinal axes of which delimiting areas. Preferably, at least one tab with a bearing is arranged at these end regions.

Erfindungsgemäß sind im Bereich zumindest eines der beiden Tragzapfen zumindest zwei horizontale Verbindungselemente angeordnet, wobei alle im Bereich der Tragzapfen angeordneten horizontalen Verbindungselemente in der selben Ebene liegen und wobei diese Ebene bei aufrechter Position des Konvertergefäßes, wenn die Konverterachse parallel zum Lot ausgerichtet ist, unterhalb oder oberhalb der Tragringebene liegt.According to the invention at least two horizontal connecting elements are arranged in the region of at least one of the two trunnions, wherein all horizontal connecting elements arranged in the region of the trunnions lie in the same plane and wherein this plane is in an upright position of the converter vessel when the converter axis is aligned parallel to the perpendicular, below or lies above the support ring level.

Das Konvertergefäß kann verschiedene Kippositionen einnehmen. Beispielsweise wird das Konvertergefäß bei einer Chargierung von flüssigem Roheisen gekippt und nimmt dabei eine Chargierposition ein. Beim Abstich wird das Konvertergefäß ebenfalls gekippt und nimmt dabei eine Abstichposition ein. Unter gekipptem Konverter ist eine vom Lot, welches senkrecht zu Niveauflächen des Erdschwerefelds steht, abweichende Lage der Konverterachse zu verstehen. In der Chargierposition schließt die Konverterachse mit dem Lot typischerweise einen Winkel von 50° bis 60° ein, in der Abstichposition typischerweise 80° bis 120°.The converter vessel can take various tilting positions. For example, the converter vessel is tilted during a charging of molten pig iron and thereby assumes a charging position. When tapping the converter vessel is also tilted and takes a tapping position. Under tilted converter is to be understood by the Lot, which is perpendicular to Niveauflächen the earth's gravity field, deviating position of the converter axis. In the charging position, the converter axis typically includes an angle of 50 ° to 60 ° with the solder, typically 80 ° to 120 ° in the tapping position.

Bei aufrechter Position des Konvertergefäßes, wenn die Konverterachse parallel zum Lot ausgerichtet ist, sind die horizontalen Verbindungselemente vorzugsweise unter dem Tragring angeordnet.In an upright position of the converter vessel, when the converter axis is aligned parallel to the solder, the horizontal connecting elements are preferably arranged below the support ring.

Die erfindungsgemäße Anordnung, bei welcher im Bereich zumindest eines der beiden Tragzapfen zumindest zwei horizontale Verbindungselemente angeordnet sind, hat den Vorteil, dass bei den unterschiedlichen Kippositionen des Konvertergefäßes, diese im Bereich des Tragzapfens angeordneten horizontalen Verbindungselemente, beziehungsweise deren Lager, auf Grund der Aufteilung der Gewichtskräfte des Konvertergefäßes - und gegebenenfalls dessen Inhalt - auf mehrere horizontale Verbindungselemente geringeren Belastungen ausgesetzt sind als dies bei im Stand der Technik offenbarten Ausführungen bekannt ist.The arrangement according to the invention, in which at least two horizontal connecting elements are arranged in the region of at least one of the two supporting pins, has the advantage that, in the case of the different tilting positions of the converter vessel, these horizontal connecting elements arranged in the region of the supporting journal, or their bearings, due to the division of the Weight forces of the converter vessel - and optionally its contents - are exposed to lower loads on several horizontal fasteners than is known in the embodiments disclosed in the prior art.

Dadurch können diese horizontalen Verbindungselemente und deren Lager in diesem Bereich kleiner ausgeführt werden, wodurch sich eine Verringerung des notwendigen Platzbedarfes für diese horizontalen Verbindungselemente sowie deren Lager ergibt. Der für das Konvertergefäß zur Verfügung stehende Platz sowie der erzielbare Durchmesser des Konvertergefäßes können dadurch erhöht werden.As a result, these horizontal connecting elements and their bearings can be made smaller in this area, resulting in a reduction in the space required for these horizontal fasteners and their bearings. The available space for the converter vessel and the achievable diameter of the converter vessel can be increased thereby.

Zusätzlich wird bei den unterschiedlichen Kippositionen durch die geringeren Belastungen der im Bereich zumindest eines der Tragzapfen angeordneten horizontalen Verbindungselemente sowie deren Lager deren Lebensdauer erhöht.In addition, the service life is increased in the different tilting positions by the lower loads of arranged in the region of at least one of the support pins horizontal connecting elements and their bearings.

Nachteilig bei den aus dem Stand der Technik bekannten kippbaren Konvertern ist, dass die Belastung im Bereich eines der Tragzapfen bei den unterschiedlichen Kippositionen des Konvertergefäßes von jeweils nur einem einzigen in diesem Bereich der Tragzapfen angeordneten horizontalen Verbindungselement beziehungsweise dessen Lager aufgenommen wird.A disadvantage of the tiltable converters known from the prior art is that the load in the region of one of the support pins is accommodated by only a single horizontal connection element or its bearing arranged in the region of the support journal at the different tilting positions of the converter vessel.

Eine bevorzugte Ausführungsform des kippbaren Konverters ist dadurch gekennzeichnet, dass das Aufhängungssystem vier horizontale Verbindungselemente umfasst, wobei jeweils zwei der horizontalen Verbindungselemente auf der Festlagerseite beziehungsweise auf der Loslagerseite des Tragrings im Bereich der Tragzapfen angeordnet sind.A preferred embodiment of the tiltable converter is characterized in that the suspension system comprises four horizontal connecting elements, wherein in each case two of the horizontal connecting elements on the fixed bearing side or are arranged on the floating bearing side of the support ring in the region of the trunnions.

Bei dieser Ausführungsform umfasst das Aufhängungssystem vier horizontale Verbindungselemente. Umfassen ist in diesem Zusammehang so zu verstehen, dass diese Ausführungsform genau vier horizontale Verbindungselemente enthalten kann oder mehr als vier horizontale Verbindungselemente enthalten kann. In jedem Fall sind im Bereich der Tragzapfen, sowohl auf der Festlagerseite des Tragrings als auch auf der Loslagerseite des Tragrings, jeweils genau zwei horizontale Verbindungselemente angeordnet. Vorzugsweise enthält diese Ausführungsform genau vier horizontale Verbindungselemente.In this embodiment, the suspension system comprises four horizontal connection elements. In this context, it should be understood that this embodiment can contain exactly four horizontal connecting elements or can contain more than four horizontal connecting elements. In any case, exactly two horizontal connecting elements are arranged in the region of the trunnions, both on the fixed bearing side of the supporting ring and on the movable bearing side of the supporting ring. Preferably, this embodiment contains exactly four horizontal connecting elements.

Die Anordnung von genau zwei horizontalen Verbindungselementen im Bereich jedes der Tragzapfen hat den Vorteil, dass bei den unterschiedlichen Kippositionen des Konvertergefäßes, die in diesen Bereichen des Tragzapfens angeordneten horizontalen Verbindungselemente, beziehungsweise deren Lager, auf Grund der Aufteilung der Gewichtskräfte des Konvertergefäßes - und gegebenenfalls dessen Inhalt - auf die zwei horizontalen Verbindungselemente, geringeren Belastungen ausgesetzt sind als dies bei im Stand der Technik offenbarten Ausführungen bekannt ist.The arrangement of exactly two horizontal connecting elements in the region of each of the supporting pins has the advantage that at the different tilting positions of the converter vessel, the horizontal connecting elements arranged in these regions of the supporting journal, or their bearings, due to the division of the weight forces of the converter vessel - and possibly its Content - are exposed to the two horizontal fasteners, lower loads than is known in the art disclosed embodiments.

Dadurch können die horizontalen Verbindungselemente und deren Lager in diesen Bereichen kleiner ausgeführt werden, wodurch sich eine Verringerung des notwendigen Platzbedarfes für die horizontalen Verbindungselemente sowie deren Lager ergibt. Der für das Konvertergefäß zur Verfügung stehende Platz sowie der erzielbare Durchmesser des Konvertergefäßes können dadurch erhöht werden.As a result, the horizontal connecting elements and their bearings can be made smaller in these areas, resulting in a reduction in the space required for the horizontal fasteners and their bearings. The available space for the converter vessel and the achievable diameter of the converter vessel can be increased thereby.

In der erfindungsgemäßen Ausführungsform des kippbaren Konverters ist eine von den Tragzapfen gebildete Kippachse vorhanden, wobei die Bereiche der Tragzapfen durch jeweils zwei im Grundriss des Konvertergefäßes symmetrisch zur Kippachse liegende und von der Konverterachse ausgehende Geraden, welche einen Winkel von bis zu 60°, bevorzugt einen Winkel von bis zu 55° einschließen, festgelegt sind.In the embodiment of the tiltable converter according to the invention, a tilting axis formed by the support pins is present, the areas of the support pins being symmetrical in each case in the plan view of the converter vessel to the tilting axis lying and emanating from the converter axis straight lines, which include an angle of up to 60 °, preferably an angle of up to 55 °, are fixed.

Im Grundriss des Konvertergefäßes wird das Konvertergefäß in Blickrichtung parallel zur Konverterachse betrachtet - entweder von oben oder von unten.In the plan view of the converter vessel, the converter vessel is viewed in the direction parallel to the converter axis - either from above or from below.

Unter Kippachse ist jene Achse zu verstehen, um die das Konvertergefäß in die verschiedenen Kippositionen kippbar ist.Tilting axis is to be understood as that axis about which the converter vessel can be tilted into the various tilting positions.

Die Tragzapfen umfassen Längsachsen, die mit der Kippachse des Konvertergefäßes übereinstimmen.The support pins comprise longitudinal axes which coincide with the tilt axis of the converter vessel.

Betrachtet man das Konvertergefäß im Grundriss, so unterteilen die Geraden den Tragringumfang in Sektorbereiche. Jene Sektorbereiche des Tragringumfangs, die einen Tragzapfen umfassen, entsprechen den erfindungsgemäßen Bereichen der Tragzapfen. Der Winkel, der jeweils durch die beiden Geraden eingeschlossen wird, wird durch die Kippachse in jeweils zwei gleich große Teile unterteilt.Looking at the converter vessel in plan, the lines divide the support ring circumference in sector areas. Those sector areas of the support ring circumference, which comprise a support pin, correspond to the areas according to the invention of the support pins. The angle, which is enclosed in each case by the two straight lines, is subdivided by the tilting axis into two parts of equal size.

Die beiden von der Konverterachse ausgehenden Geraden schließen mindestens einen Winkel von 10°, bevorzugt 15° ein, wobei sie auch einen Winkel von genau 10°, beziehungsweise von genau 15° einschließen können. Die beiden von der Konverterachse ausgehenden Geraden schließen einen Winkel von bis zu 60°, bevorzugt einen Winkel von bis zu 55° ein, wobei sie auch einen Winkel von genau 60°, beziehungsweise von genau 55° einschließen können.The two outgoing from the converter axis straight lines include at least an angle of 10 °, preferably 15 °, and they can also include an angle of exactly 10 °, or of exactly 15 °. The two outgoing from the converter axis straight lines close an angle of up to 60 °, preferably an angle of up to 55 °, and they can also include an angle of exactly 60 °, or of exactly 55 °.

Durch die Anordnung der horizontalen Verbindungselemente innerhalb dieser erfindungsgemäßen Bereiche der Tragzapfen befinden sich die horizontalen Verbindungselemente sehr nahe an den Tragzapfen.Due to the arrangement of the horizontal connecting elements within these inventive areas of the trunnions, the horizontal connecting elements are very close to the trunnions.

Dadurch bieten andere, weil freie, Bereiche am Konvertergefäß beziehungsweise am Tragring die Möglichkeit, zusätzliche Anordnungen und Einrichtungen am Konvertergefäß beziehungsweise am Tragring anzubringen.As a result, other, because free, areas on the converter vessel or on the support ring offer the possibility to install additional arrangements and facilities on the converter vessel or on the support ring.

Eine bevorzugte Ausführungsform des kippbaren Konverters ist dadurch gegeben, dass die zwei jeweils im Bereich der Tragzapfen angeordneten horizontalen Verbindungselemente im Grundriss des Konvertergefäßes symmetrisch zur Kippachse angeordnet sind.A preferred embodiment of the tiltable converter is given by the fact that the two arranged in the region of the support pins horizontal connecting elements are arranged in the plan view of the converter vessel symmetrical to the tilting axis.

Neben den bereits genannten vorteilhaften Wirkungen der Erfindung hat diese Ausführungsform den zusätzlichen Vorteil, dass bei den unterschiedlichen Kippositionen des Konvertergefäßes, die in diesen Bereichen des Tragzapfens angeordneten horizontalen Verbindungselemente, beziehungsweise deren Lager, auf Grund einer gleichmäßigen Aufteilung der Gewichtskräfte des Konvertergefäßes - und gegebenenfalls dessen Inhalt - auf die in diesen Bereichen angeordneten horizontalen Verbindungselemente, geringeren Belastungen ausgesetzt sind als dies bei im Stand der Technik offenbarten Ausführungen bekannt ist.In addition to the advantageous effects of the invention already mentioned, this embodiment has the additional advantage that at the different tilting positions of the converter vessel, arranged in these areas of the trunnion horizontal connecting elements, or their bearings, due to a uniform distribution of the weight forces of the converter vessel - and optionally its Content - are placed on the arranged in these areas horizontal fasteners, lower loads than is known in the art disclosed embodiments.

Dadurch können alle in den Bereichen der beiden Tragzapfen angeordneten horizontalen Verbindungselemente und deren Lager kleiner ausgeführt werden. Es ergibt sich eine Verringerung des notwendigen Platzbedarfes für die horizontalen Verbindungselemente sowie deren Lager und der für das Konvertergefäß zur Verfügung stehende Platz sowie der erzielbare Durchmesser des Konvertergefäßes können dadurch erhöht werden.As a result, all arranged in the areas of the two support pins horizontal connecting elements and their bearings can be made smaller. This results in a reduction in the space required for the horizontal connecting elements and their bearings and the space available for the converter vessel space and the achievable diameter of the converter vessel can be increased.

In der erfindungsgemäßen Ausführungsform des kippbaren Konverters greifen die horizontalen Verbindungselemente in Konverteranlenkpunkten beziehungsweise in Tragringanlenkpunkten am Konvertergefäß beziehungsweise am Tragring gelenkig an, wobei im Grundriss zumindest ein horizontales Verbindungselement im Bereich der Tragzapfen in seinem Konverteranlenkpunkt normal oder im Wesentlichen normal zu einem von der Konverterachse ausgehenden und seinen Konverteranlenkpunkt durchstoßenden Strahl ausgerichtet ist.In the embodiment of the tiltable converter according to the invention, the horizontal connecting elements articulate in converter connection points or in support ring connection points on the converter vessel or on the support ring, with at least one horizontal connection element in the area of the support pins in its converter connection point in plan view is aligned normal or substantially normal to an emanating from the converter axis and piercing its Konverteranlenkpunkt beam.

Dies gilt für die Geometrie des Konvertergefäßes, wenn es kalt ist. Unter einem kalten Konvertergefäß ist ein Konvertergefäß zu verstehen, das nicht mit schmelzflüssigen Materialien wie beispielsweise Eisen- oder Stahlschmelzen gefüllt ist. Das kalte Konvertergefäß weist Raumtemperatur auf.This applies to the geometry of the converter vessel when it is cold. A cold converter vessel means a converter vessel that is not filled with molten materials such as iron or steel melts. The cold converter vessel has room temperature.

Unter dem Ausdruck "im Wesentlichen normal" ist eine maximale Abweichung der Längsachse des horizontalen Verbindungselements von der Normalen bezüglich des Strahls von +/-5° zu verstehen.By the term "substantially normal" is meant a maximum deviation of the longitudinal axis of the horizontal connecting element from the normal with respect to the beam of +/- 5 °.

Vorzugsweise sind alle im Bereich der Tragzapfen angeordneten horizontalen Verbindungselemente normal oder im Wesentlichen normal zu dem von der Konverterachse ausgehenden und seinen jeweiligen Konverteranlenkpunkt durchstoßenden Strahl ausgerichtet.Preferably, all arranged in the region of the support pins horizontal connecting elements are normal or substantially normal to the emanating from the converter axis and piercing its respective Konverteranlenkpunkt beam.

Diese Ausführungsform der Erfindung hat den Vorteil, dass Zwangskräfte, die im Fall einer statisch unbestimmten Art des Aufhängungssystems auftreten, minimiert werden. Zwangskräfte sind Kräfte, die auf Grund einer geometrischen Verformung des Konvertergefäßes auf das Aufhängungssystem wirken.This embodiment of the invention has the advantage that constraining forces that occur in the case of a statically indeterminate type of suspension system are minimized. Forcing forces are forces that act on the suspension system due to geometric deformation of the converter vessel.

In einer weiteren bevorzugten Ausführungsform des kippbaren Konverters ist der im Grundriss des Konvertergefäßes gemessene Normalabstand zwischen jeweils einem Konverteranlenkpunkt eines horizontalen Verbindungselements im Bereich der Tragzapfen und der Kippachse größer als der Normalabstand zwischen jeweils einem Tragringanlenkpunkt eines horizontalen Verbindungselements im Bereich der Tragzapfen und der Kippachse.In a further preferred embodiment of the tiltable converter, the normal distance, measured in the plan view of the converter vessel, between each converter connection point of a horizontal connection element in the region of the support pins and the tilt axis is greater than the normal distance between in each case one support ring connection point of a horizontal connection element in the region of the support pins and the tilt axis.

Durch diese weitere bevorzugte Ausführungsform des kippbaren Konverters werden die Zwangskräfte noch weiter minimiert.By this further preferred embodiment of the tiltable converter, the constraining forces are further minimized.

Die erfindungsgemäße Ausführungsform des kippbaren Konverters ist dadurch gekennzeichnet, dass die horizontalen Verbindungselemente mittels in Lagern der horizontalen Verbindungselemente gelagerten Anlenkelementen beweglich an am Konvertergefäß befestigten Konverterstützlaschen und an am Tragring befestigten Tragringstützlaschen angelenkt sind.The embodiment of the tiltable converter according to the invention is characterized in that the horizontal connecting elements are articulated by means mounted in bearings of the horizontal connecting elements articulated movable attached to the converter vessel converter support brackets and attached to the support ring support ring support brackets.

Vorzugsweise sind die in den jeweiligen Bereichen der Tragzapfen angeordneten horizontalen Verbindungselemente an der gleichen Tragringstützlasche angelenkt.Preferably, arranged in the respective regions of the support pins horizontal connecting elements are hinged to the same support ring support tab.

Dadurch ergibt sich eine einfache und kompakte Ausführungsform des Aufhängungssystems unter gleichzeitiger Verringerung des Platzbedarfes.This results in a simple and compact embodiment of the suspension system while reducing the space required.

In einer weiteren bevorzugten Ausführungsform ist zumindest ein Anlenkelement als exzentrischer Bolzen ausgeführt.In a further preferred embodiment, at least one articulation element is designed as an eccentric pin.

Die Ausführung zumindest eines Anlenkelements als exzentrischer Bolzen ermöglicht die Einstellung jenes horizontalen Verbindungselements, das mittels des exzentrischen Bolzens an einer Konverterstützlasche oder an einer Tragringstützlasche angelenkt ist.The execution of at least one articulation element as an eccentric pin allows the adjustment of that horizontal connecting element, which is articulated by means of the eccentric bolt on a converter support tab or on a support ring support tab.

Unter Einstellung ist die Verstellung der Position des Lagers des horizontalen Verbindungselements zu verstehen.Setting is the adjustment of the position of the bearing of the horizontal connection element.

Damit ergibt sich der Vorteil, dass der Abstand der Lager des entsprechenden horizontalen Verbindungselements an die Länge des horizontalen Verbindungselements angepasst werden kann.This results in the advantage that the distance between the bearings of the corresponding horizontal connecting element can be adapted to the length of the horizontal connecting element.

Es können auch mehrere oder alle Anlenkelemente als exzentrischer Bolzen ausgeführt sein.It can also be designed as eccentric bolt several or all of the hinge elements.

Die nicht als exzentrische Bolzen ausgeführten Anlenkelemente sind beispielsweise als normale Bolzen ausgeführt.The non-eccentric bolt designed coupling elements are designed for example as a normal bolt.

Die Bolzen durchsetzen jeweils sowohl die Laschen der horizontalen Verbindungselemente als auch die entsprechenden Konverterstützlaschen beziehungsweise Tragringstützlaschen.The bolts enforce both the tabs of the horizontal connecting elements as well as the corresponding converter support tabs or support ring support tabs.

Die Einstellung eines oder mehrerer horizontalen Verbindungselemente mittels der exzentrischen Bolzen ist insbesondere bei der Montage des Aufhängungssystems von Vorteil.The adjustment of one or more horizontal connecting elements by means of the eccentric bolts is particularly advantageous during assembly of the suspension system.

In aus dem Stand der Technik bekannten Verfahren wird eine derartige Einstellung oftmals durch eine genaue Positionierung des Konvertergefäßes und des Aufhängungssystems mit anschließender aufwendiger Montageschweißung realisiert.In known from the prior art, such adjustment is often realized by an accurate positioning of the converter vessel and the suspension system with subsequent complex assembly welding.

Eine Ausführungsform des kippbaren Konverters zeichnet sich dadurch aus, dass die Anlenkelemente im Wesentlichen parallel zur Konverterachse ausgerichtet sind.An embodiment of the tiltable converter is characterized in that the coupling elements are aligned substantially parallel to the converter axis.

In einer weiteren Ausführungsform des kippbaren Konverters umfasst das Aufhängungssystem drei, vorzugsweise vier vertikale Verbindungselemente, die jeweils mit ihren gegenüberliegenden Enden am Konvertergefäß beziehungsweise am Tragring angreifen und die mit der Konverterachse einen Winkel von 0° bis 45°, vorzugsweise einen Winkel von 10° bis 30° einschließen.In a further embodiment of the tiltable converter, the suspension system comprises three, preferably four vertical connecting elements which each engage with their opposite ends on the converter vessel or on the support ring and with the converter axis an angle of 0 ° to 45 °, preferably an angle of 10 ° Enclose 30 °.

Die vertikalen Verbindungselemente haben vorzugsweise eine längliche Form mit einer geraden Längsachse. Wenn die vertikalen Verbindungselemente mit der Konverterachse einen Winkel von 0° bis 45°, vorzugsweise einen Winkel von 10° bis 30° einschließen, dann schließen damit auch ihre jeweiligen Längsachsen einen Winkel von 0° bis 45°, vorzugsweise einen Winkel von 10° bis 30° mit der Konverterachse ein. Unterschiedliche vertikale Verbindungselemente beziehungsweise deren Längsachsen können unterschiedliche Winkel mit der Konverterachse einschließen.The vertical connecting elements preferably have an elongated shape with a straight longitudinal axis. If the vertical connecting elements form an angle of 0 ° to 45 °, preferably an angle of 10 ° to 30 ° with the converter axis, then also their respective longitudinal axes close an angle of 0 ° to 45 °, preferably an angle of 10 ° 30 ° with the converter axis. Different vertical connection elements or their Longitudinal axes may include different angles with the converter axis.

Vorzugsweise umfasst das Aufhängungssystem genau vier vertikale Verbindungselemente.Preferably, the suspension system includes exactly four vertical links.

In einer bevorzugten Ausführungsform weisen die horizontalen Verbindungselemente und die vertikalen Verbindungselemente im Wesentlichen die gleiche Bauweise und/oder im Wesentlichen die gleiche Baugröße auf.In a preferred embodiment, the horizontal connecting elements and the vertical connecting elements have substantially the same construction and / or substantially the same size.

Die im Wesentlichen gleich ausgeführten Verbindungselemente führen zu einem verringerten Aufwand an Lagerlogistik, da weniger unterschiedliche Verbindungselemente gelagert werden müssen. Dies verursacht daher vergleichsweise niedrige Lagerhaltungskosten beziehungsweise Logistikkosten.The essentially identical connecting elements lead to a reduced expenditure on storage logistics, since fewer different connecting elements must be stored. This therefore causes comparatively low storage costs or logistics costs.

Ein weiterer Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Umbau eines kippbareren Konverters mit einem Konvertergefäß und einer dem Konvertergefäß zugeordneten Konverterachse, einen das Konvertergefäß mit Abstand umfassenden Tragring mit zwei diametral gegenüberliegenden und eine Kippachse bildende Tragzapfen, welche jeweils auf einer Festlagerseite beziehungsweise auf einer Loslagerseite des Tragrings angeordnet sind und ein Aufhängungssystem zur Abstützung des Konvertergefäßes am Tragring. Erfindungsgemäß werden im Bereich zumindest eines der beiden Tragzapfen zumindest zwei horizontale Verbindungselemente angeordnet, wobei alle im Bereich der Tragzapfen angeordneten horizontalen Verbindungselemente in der selben Ebene liegen und wobei diese Ebene bei aufrechter Position des Konvertergefäßes, wenn die Konverterachse parallel zum Lot ausgerichtet ist, unterhalb oder oberhalb der Tragringebene liegt.Another object of the present invention is a method for converting a tiltable converter with a converter vessel and the converter vessel associated converter axis, the converter vessel at a distance comprehensive support ring with two diametrically opposite and a tilting axis forming trunnions, each on a fixed bearing side or on a non-locating side the support ring are arranged and a suspension system for supporting the converter vessel on the support ring. According to the invention at least two horizontal connecting elements are arranged in the region of at least one of the two trunnions, wherein all horizontal connecting elements arranged in the region of the trunnions lie in the same plane and this plane is in the upright position of the converter vessel, if the converter axis is aligned parallel to the perpendicular, below or lies above the support ring level.
