Description
Die Erfindung betrifft eine pyrometallurgische Anlage, insbesondere eine Stahlwerksanlage, umfassend wenigstens ein metallurgisches Gefäß mit einer Einhausung, wenigstens eine Beschickungsbühne und wenigstens eine Beschickungs-Toranlage mit welcher eine Beschickungsöffnung und/oder eine Entleerungsöffnung in der Einhausung verschließbar ist.The invention relates to a pyrometallurgical system, in particular a steelworks system, comprising at least one metallurgical vessel with a housing, at least one loading platform and at least one loading door system with which a loading opening and/or an emptying opening in the housing can be closed.
Die Erfindung betrifft weiterhin eine Beschickungs-Toranlage für eine pyrometallurgische Anlage, beispielsweise für einen Stahlwerksanlage mit wenigstens einem metallurgischen Gefäß mit einer Einhausung, welche eine Beschickungsöffnung aufweist und mit wenigstens einer Beschickungsbühne.The invention also relates to a loading door system for a pyrometallurgical system, for example for a steelworks system, with at least one metallurgical vessel with a housing which has a loading opening and with at least one loading platform.
Beispielsweise Beschickungs-Toranlagen von Konverter Stahlwerken haben unter anderem die Aufgabe, die Umgebung und das Personal vor Hitze, Rauchgasen, Schlacke und Stahlspritzern zu schützen. Auf der Vorderseite der üblicherweise innen mit einem Hitzeschutz versehenen Einhausung des Konverters sind in der Regel auf Schienen verfahrbare Beschickungstore angeordnet.For example, loading gate systems of converter steelworks have the task of protecting the environment and the personnel from heat, smoke gases, slag and steel spatter. On the front side of the converter housing, which is usually provided with heat protection on the inside, there are usually loading gates that can be moved on rails.
Im Stand der Technik sind Beschickungstore bekannt, die auf einem Schienensystem einer Beschickungsbühne oder auf einem Aufbau der Bühnenkante nahe dem Konverter abgestützt und verfahrbar sind.Loading gates are known in the prior art, which are supported and movable on a rail system of a loading platform or on a structure of the platform edge near the converter.
Die Verwendung eines Aufbaus auf der Bühnenkante hat den Nachteil, dass der zur Wartung des Konverters verfügbare Raum reduziert wird. Ein Aufbau stört ebenfalls beim Beschicken des Konverters mit der Roheisenpfanne, da sich deren Unterkante oft nahe der Bühnenoberfläche befindet, wenn die Pfanne an einem Kran hängend zum Konverter geführt wird.The disadvantage of using a stage edge structure is that it reduces the space available to service the converter. A structure also interferes with loading the converter with the pig iron ladle, since its lower edge is often close to the platform surface when the ladle is guided to the converter hanging on a crane.
Das Verfahren der Beschickungstore auf einem Schienensystem ist mit dem Nachteil behaftet, dass das Schienensystem in der Nähe des Konverters verschmutzungsanfällig ist und eine Gefahrenquelle bzw. Stolperfalle darstellt.The process of loading gates on a rail system has the disadvantage that the rail system in the vicinity of the converter is susceptible to dirt and represents a source of danger and tripping hazards.

Der Erfindung liegt die Aufgabe zugrunde, eine Anlage mit einer Beschickungs-Toranlage bereitzustellen, die wartungsarm und weniger störanfällig als die bekannten Systeme ist.The object of the invention is to provide a system with a loading door system that requires little maintenance and is less susceptible to faults than the known systems.
Der Erfindung liegt weiterhin die Aufgabe zugrunde, eine entsprechende Beschickungs-Toranlage für eine solche Anlage bereitzustellen.The invention is also based on the object of providing a corresponding loading door system for such a system.
Die Aufgabe wird gelöst mit den Merkmalen des Anspruchs 1 sowie mit den Merkmalen des Anspruchs 9. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The object is achieved with the features of claim 1 and with the features of
Ein Gesichtspunkt der Erfindung betrifft eine pyrometallurgische Anlage mit wenigstens einem metallurgischen Gefäß in einer Einhausung, wenigstens einer Beschickungsbühne und wenigstens einer Beschickungs-Toranlage, mit welcher eine Beschickungsöffnung und/oder eine Entleerungsöffnung in der Einhausung verschließbar ist, wobei die Beschickungs-Toranlage wenigstens einen Beschickungstorflügel umfasst, welcher hängend auf einem Träger abgestützt ist und welche auf dem Träger verfahrbar ist, wobei der Träger von einem ortsfest auf der Beschickungsbühne angeordneten Gestell gehalten wird.One aspect of the invention relates to a pyrometallurgical system with at least one metallurgical vessel in a housing, at least one loading platform and at least one loading door system, with which a loading opening and/or an emptying opening in the housing can be closed, the loading door system having at least one loading door leaf which is suspended on a carrier and which can be moved on the carrier, the carrier being held by a frame arranged in a stationary manner on the loading platform.
Die pyrometallurgische Anlage kann beispielsweise als Stahlwerksanlage ausgebildet sein. Der fachkundige Leser wird erkennen, dass die Konfiguration der Anlage für die Erfindung nicht kritisch ist. Das pyrometallurgische Gefäß kann beispielsweise ein Konverter sein.The pyrometallurgical plant can be designed as a steelworks plant, for example. The skilled reader will recognize that the configuration of the Plant is not critical to the invention. The pyrometallurgical vessel can be a converter, for example.
Das Gestell kann derart ausgebildet sein, dass die Abstützung des Trägers auf der Beschickungsbühne außerhalb des Beschickungsbereichs, d. h. außerhalb der Beschickungsöffnung und/oder der Entleerungsöffnung angeordnet ist. Auf diese Art und Weise kann ein Beschickungstor, das beispielsweise Abmessungen von 10 × 5 m und ein verhältnismäßig hohes Gewicht von bis zu 20 t aufweisen kann, sicher auf der Beschickungsbühne abgestützt werden. Die Aufhängung auf dem Träger ermöglicht es, die Führung des Beschickungstorflügels in einen Bereich zu verlagern, der weniger verschmutzungsanfällig ist. Darüber hinaus hat die erfindungsgemäße Konstruktion den Vorzug, dass die Beschickungsbühne im Bereich der Beschickungsöffnung ohne Schienen und ohne andere Aufbauten ausgeführt sein kann.The frame can be designed in such a way that the support of the carrier on the loading platform is outside the loading area, i. H. is arranged outside the loading opening and/or the emptying opening. In this way, a loading door, which can for example have dimensions of 10×5 m and a relatively high weight of up to 20 t, can be securely supported on the loading platform. The suspension on the support makes it possible to move the guidance of the loading gate leaf to an area that is less prone to contamination. In addition, the construction according to the invention has the advantage that the loading platform can be designed without rails and without other structures in the area of the loading opening.
Die erfindungsgemäße Lösung hat den Vorzug, dass weniger Störungen beim Betrieb der Beschickungstore auftreten. Es sind deutlich weniger und einfachere Reinigungsarbeiten auf der Beschickungsbühne erforderlich. Schienen und Räder der Beschickungs-Toranlage besitzen eine höhere Standzeit. Auf der Beschickungstorbühne im mittleren Bereich der Einhausung ist mehr Platz für Wartungsarbeiten am Gefäß oder im Inneren der Einhausung, beispielsweise zum Erneuern des dort vorgesehenen Hitzeschutzes. Darüber hinaus wird die Sicherheit für das Personal der Stahlwerksanlage verbessert, insbesondere dadurch, dass die Beschickungs-Toranlage zuverlässiger betreibbar ist, sodass kein Betrieb des Gefäßes mit geöffneten Toren erfolgt.The solution according to the invention has the advantage that fewer disruptions occur when the loading gates are in operation. Significantly less and simpler cleaning work is required on the loading platform. Rails and wheels of the loading gate system have a longer service life. On the loading gate platform in the middle of the housing there is more space for maintenance work on the vessel or inside the housing, for example to replace the heat protection provided there. In addition, the safety for the personnel of the steel plant is improved, in particular because the charging gate system can be operated more reliably, so that the vessel is not operated with the gates open.
Zweckmäßigerweise umfasst die Beschickungs-Toranlage zwei Beschickungstorflügel, die vorzugsweise in einer Ebene gegeneinander schließend ausgebildet sind.The loading door system expediently comprises two loading door wings, which are preferably designed to close against one another in one plane.
Die Beschickungstorflügel können so aufgehängt sein, dass diese mit einem unteren Abstand zu der Beschickungsbühne aufgehängt sind, sodass unterhalb der Beschickungstorflügel zwischen diesen und der Beschickungsbühne ein größerer Spalt verbleibt, wodurch sichergestellt wird, dass etwaige Schlacke Ansammlungen auf der Beschickungsbühne die Zugänglichkeit der Beschickungstorflügel nicht beeinträchtigt.The loading gate leaves may be hung such that they are hung at a lower clearance from the loading floor so that there is a larger gap below the loading door wings between them and the loading floor, thereby ensuring that any slag accumulation on the loading floor does not impede accessibility to the loading door wings .
Bei einer weiteren vorteilhaften Variante der Anlage gemäß der Erfindung ist vorgesehen, die Beschickungs-Toranlage eine Torschürze umfasst, die einen größeren Zwischenraum zwischen den Beschickungstorflügeln und der Beschickungsbühne verschließt. Diese im Wesentlichen dreiteilige Ausführung der Beschickungs-Toranlage hat den Vorzug, dass die Beschickungstorflügel etwas kleiner und leichter ausfallen können, sodass die Aufhängung der Beschickungstorflügel geringerer Lasten aufnehmen müssen. Die Torschürze kann so ausgebildet sein, dass diese bedarfsweise entfernt werden kann, sodass die Beschickungsöffnung bedarfsweise vergrößert werden kann.In a further advantageous variant of the system according to the invention, the loading gate system comprises a gate apron which closes a larger space between the loading gate leaves and the loading platform. This essentially three-part design of the loading gate system has the advantage that the loading gate wings can be somewhat smaller and lighter, so that the suspension of the loading gate wings has to absorb lower loads. The gate apron can be designed in such a way that it can be removed if necessary, so that the loading opening can be enlarged if necessary.
Eine weitere Entlastung der Aufhängung der Beschickungstorflügel ergibt sich, wenn die Beschickungstorflügel auf der Torschürze verschiebbar geführt sind. Die Torschürze bildet in diesem Fall einer Gleitführung und untere Abstützung der Beschickungstorflügel. Die Torschürze kann beispielsweise mittels Zapfen in gabelförmige Aufnahmen an dem Gestell eingehängt sein. Die Torschürze kann so ausgebildet sein, dass diese mittels eines Krans oder der gleichen Hebezeugs in die Einbaulage verbracht werden kann. Alternativ kann die Torschürze so ausgebildet und angeordnet sein, dass sie auf die Beschickungsbühne umgelegt werden kann.A further reduction in the load on the suspension of the loading gate leaves results when the loading gate leaves are slidably guided on the gate apron. In this case, the gate apron forms a sliding guide and lower support for the loading gate wings. The gate apron can be hung in fork-shaped receptacles on the frame, for example by means of pins. The gate apron can be designed in such a way that it can be brought into the installation position by means of a crane or the same lifting gear. Alternatively, the gate apron can be designed and arranged in such a way that it can be folded onto the loading platform.
Die Torschürze kann wenigstens eine Öffnung zur Probenentnahme oder Inspektion des Innenraums der Konverter Einhausung aufweisen.The gate apron can have at least one opening for taking samples or inspecting the interior of the converter housing.
Bei einer zweckmäßigen Ausgestaltung der Anlage gemäß der Erfindung ist vorgesehen, dass der Träger ein Profil aufweist, das wenigstens eine Fahrspur für wenigstens ein Stützrad wenigstens eines Beschickungstorflügels bildet.In an expedient configuration of the system according to the invention, it is provided that the carrier has a profile which forms at least one track for at least one support wheel of at least one loading gate leaf.
Die Beschickungs-Toranlage kann wenigstens einen Fahrantrieb aufweisen, der wenigstens ein angetriebenes Stützrad umfasst.The loading gate system can have at least one travel drive, which includes at least one driven support wheel.
Zweckmäßigerweise bildet die Fahrspur eine Führung für das wenigstens eine Stützrad.The lane expediently forms a guide for the at least one support wheel.
Bei einer besonders günstigen und vorteilhaften Ausgestaltung der Anlage ist vorgesehen, dass der wenigstens eine Beschickungstorflügel wenigstens ein oberes und ein unteres Stützrad aufweist, die in der Fahrtrichtung mit Abstand zueinander auf gegenüberliegenden Seiten des Massenschwerpunkts des Beschickungstorfflügels angeordnet sind, sodass der Träger in vorteilhafter Art und Weise eine Momentenstütze für den betreffenden Beschickungstorflügel bildet.In a particularly favorable and advantageous embodiment of the system, it is provided that the at least one loading gate leaf has at least one upper and one lower support wheel, which are arranged at a distance from one another in the direction of travel on opposite sides of the center of mass of the loading gate leaf, so that the carrier can be used in an advantageous manner and Way forms a torque support for the loading gate leaf in question.
Wenigstens ein Stützrad kann wenigstens einen Spurkranz umfassen, der mit einem Führungsprofil der Fahrspur zusammenwirkt. Bei einer bevorzugten Ausführung der Anlage ist vorgesehen, dass ein oder mehrere obere Stützräder jeweils zwei Spurkränze aufweisen, die mit einem oben auf dem Träger angeordneten rechteckigen Führungsprofil der Fahrspur zusammenwirken.At least one support wheel can include at least one wheel flange that interacts with a guide profile of the lane. In a preferred embodiment of the system, it is provided that one or more upper support wheels each have two wheel flanges, which interact with a rectangular guide profile of the lane arranged on top of the carrier.
Die Erfindung betrifft weiterhin eine Beschickungs-Toranlage für eine pyrometallurgische Anlage, beispielsweise für eine Stahlwerksanlage mit wenigstens einem metallurgischen Gefäß mit einer Einhausung, beispielsweise mit einem Konverter mit einer Einhausung, welche eine Beschickungsöffnung aufweist und mit wenigstens einer Beschickungsbühne, wobei die Beschickungs-Toranlage wenigstens einen Beschickungstorflügel umfasst, welcher hängend auf einem Träger abgestützt ist und welche auf dem Träger verfahrbar ist, wobei der Träger sich auf einem ortsfest auf der Beschickungsbühne angeordneten Gestell abstützt.The invention further relates to a loading door system for a pyrometallurgical plant, for example for a steel works, with at least one metallurgical vessel with a housing, for example with a converter with a housing which has a loading opening and with at least one loading platform, the loading door system at least comprises a loading gate leaf which is supported in a suspended manner on a carrier and which is traversable on the carrier, wherein the Carrier is supported on a fixed frame arranged on the loading platform.
Vorzugsweise umfasst die Beschickungs-Toranlage zwei Beschickungstorflügel, die in einer Ebene gegeneinander geschlossen werden können bzw. geöffnet werden können.The loading gate system preferably comprises two loading gate wings which can be closed or opened in relation to one another in one plane.
