Abstract

The invention relates to a method for introducing bulk material into a metallurgical vessel, especially for introducing scrap into an arc furnace, which has at least one centrally situated electrode in an upper vessel part that is gas-tightly sealed by a lid. The bulk material is transported to the head of the metallurgical vessel in individual bulk material containers. The opening part of the bulk material container is connected to coupling parts of the lid. The bulk material is conveyed out of the container by conveying parts connected to the bulk material containers and introduced into the metallurgical vessel by access openings in the lid. In the case of a device that is suitable for carrying out this method, at least one ring-shaped part (16) of the lid (15) is rotationally connected to a lid drive system (51) in the lid plane. The rotating lid part (16) has at least one feed opening, through which the bulk material can be conveyed into the upper vessel part (11). The feed openings (16) are covered by coupling parts (31) which have a sealable wall (32). A bulk material container (41) which can be filled with bulk material can be coupled with the coupling part (31). The bulk material container (41) is connected to a conveying unit (42, 43, 44) by which means the bulk material can be conveyed into the metallurgical vessel (11) through the lid part (16), through the feed opening (17).

Description

Verfahren und Einrichtung zum Einbringen von Schüttgut in ein metallurgisches GefäßMethod and device for introducing bulk material into a metallurgical vessel

Die Erfindung betrifft ein Verfahren zum Einbringen von Schüttgut in ein metallurgisches Gefäß, insbesondere von Schrott in einen Lichtbogenofen, der in einem mit einem Deckel gasdicht verschlossenen Gefäßoberteil mindestens eine zentrisch angeordnete Elektrode aufweist und eine entsprechende Einrichtung dazu.The invention relates to a method for introducing bulk material into a metallurgical vessel, in particular scrap into an electric arc furnace, which has at least one centrally arranged electrode in an upper part of the vessel which is closed in a gas-tight manner and a corresponding device.

Metallurgische Gefäße werden üblicherweise batchweise gefüllt, so werden regelmäßig Lichtbogenöfen mittels Schrottkörben chargiert.Metallurgical vessels are usually filled in batches, so arc furnaces are regularly charged using scrap baskets.

So ist aus der EP 0 646 652 B1 eine Stahlwerkseinrichtung mit geschlossenem kippbaren Lichtbogenofen bekannt, der eine Beschickungsvorrichtung mit mindestens zwei Vorratsbehältern aufweist. Diese Vorratsbehälter werden, zu beiden Seiten des Elektrodentragarmes angeordnet, an der Hallenbühne befestigt. Die Vorratsbehälter besitzen einen während des Chargierens entfernbaren Boden. Mit diesen Behältern ist eine kontinuierliche Beschickung des Ofengefäßes nicht möglich.For example, EP 0 646 652 B1 discloses a steelworks facility with a closed, tiltable arc furnace, which has a loading device with at least two storage containers. These storage containers are arranged on both sides of the electrode support arm and fastened to the indoor stage. The storage containers have a bottom that can be removed during charging. Continuous loading of the furnace vessel is not possible with these containers.

Aus der DE 197 53 184 A1 ist eine Schmelzofenanlage zum Einschmelzen von Metallen bekannt, bei der koaxial zur Ofenhauptachse ein Zentralrohr vorgesehen ist, in dem mindestens eine Elektrode angeordnet ist und bei der am Ofenkopf ein Behälter aufsetzbar ist. In diesem Behälter wird die Charge oberhalb des mit dem Deckel verschlossenen Ofenobergefäßes zwischengelagert und durch Öffnen des Ofendeckels fällt die Charge in den Ofeninnenraum. Auch bei dieser bekannten Einrichtung ist ein kontinuierliches Befüllen des Ofens nicht möglich.DE 197 53 184 A1 discloses a melting furnace system for melting metals, in which a central tube is provided coaxially with the main furnace axis, in which at least one electrode is arranged and in which a container can be placed on the furnace head. In this container, the batch is temporarily stored above the furnace top vessel closed with the lid, and when the furnace lid is opened, the batch falls into the interior of the furnace. Continuous filling of the furnace is also not possible with this known device.

Aus der DE 44 07 861 C1 ist eine Beschickungsvorrichtung für Lichtbogenöfen bekannt, bei dem an der Ofendecke eine Ringkammer angeordnet ist, wobei in der Ringkammer eine Fahreinrichtung vorgesehen ist, an der schaltbare Lastmagnete aufgehängt sind. Seitlich in das Ofengefäß ragt mindestens eine Materialzuführung hinein, an der an der Fahreinrichtung befestigte Lastmagnete vorgesehen sind, die eine magnetische Aufnahme des Chargiermaterials ermöglichen und dieses an beliebiger Stelle innerhalb des Ofens abwerfen. Die Materialzufuhr zum Ofen erfolgt über Endlosförderbänder. Dies entspricht nicht einem Batchbetrieb mittels unabhängigen Schüttgutbehältern.From DE 44 07 861 C1, a charging device for arc furnaces is known, in which an annular chamber is arranged on the furnace ceiling, wherein in a driving device is provided on the annular chamber, on which switchable load magnets are suspended. At least one material feed protrudes laterally into the furnace vessel, on which load magnets attached to the driving device are provided, which enable the charging material to be magnetically picked up and throw it off at any point within the furnace. The material is fed to the furnace via endless conveyor belts. This does not correspond to batch operation using independent bulk containers.

Es ist Aufgabe der Erfindung, ein Verfahren und eine Einrichtung zum Einbringen von Schüttgut in ein metallurgisches Gefäß zu schaffen, welches mit einfachen, konstruktiven Mitteln betriebssicher das Schüttgut batchweise zum Gefäßkopf befördert und eine kontinuierliche Chargierung des Schüttgutes in das Gefäßoberteil ermöglicht.It is an object of the invention to provide a method and a device for introducing bulk material into a metallurgical vessel which, with simple, constructive means, reliably transports the bulk material batchwise to the vessel head and enables continuous charging of the bulk material into the upper part of the vessel.

Die Erfindung löst diese Aufgabe durch die Merkmale des Verfahrensanspruchs 1 und des Vorrichtungsanspruchs 4.The invention solves this problem by the features of method claim 1 and device claim 4.

Erfindungsgemäß werden zum Heranfördern an das metallurgische Gefäß voneinander unabhängige Schüttguteinheiten eingesetzt, beispielsweise die im Stahlwerk bekannten Schurren, wie sie beim Konverterbetrieb Verwendung finden.According to the invention, bulk material units which are independent of one another are used for conveying to the metallurgical vessel, for example the chutes known in the steelworks, as are used in converter operation.

Der das Gefäßoberteil des metallurgischen Gefäßes abschließende Deckel ist drehbar ausgestaltet und besitzt mindestens eine Öffnung. Im Bereich der Öffnung ist eine Andockeinrichtung vorgesehen, die mit dem mit Schrott gefüllten Schüttgutbehälter verbunden wird. Das Schüttgut wird aus dem Behälter herausgefördert bei gleichzeitiger Drehung des Deckels. Durch dieses Verfahren ist in einem ringförmigen Bereich der Teufe jeder beliebige Punkt der im Gefäßoberteil befindlichen Charge erreichbar.The lid closing the upper part of the metallurgical vessel is designed to be rotatable and has at least one opening. In the area of the opening, a docking device is provided, which is connected to the bulk material container filled with scrap. The bulk material is conveyed out of the container while rotating the lid. With this method, any point of the batch located in the upper part of the vessel can be reached in an annular region of the depth.

Das Ausfördern des Schüttgutes aus dem Schüttgutbehälter erfolgt gesteuert, und zwar entweder durch Ausstoßen mittels eines Schiebers, durch Transpor- tieren über ein Förderband oder durch Kippen des gesamten Behälters. Durch den Einsatz unabhängiger Schurren erhöht sich die Betriebssicherheit und es verringern sich die Ansprüche an den Schrottplatz. Darüber hinaus kann bei Ausfall eines Fördergutbehälters während seines Einsatzes am Ofenkopf dessen Funktion durch einen anderen Behälter übernommen werden. Dabei kann ein anderer Behälter an Stelle des Ausgefallenen in den Chargierbereich gebracht werden. Mögliche Fehler an dem Behälter, insbesondere an dem Antrieb der Fördervorrichtung können dann in einem gesonderten Instandhaltungsbereich gewartet werden.The bulk material is conveyed out of the bulk material container in a controlled manner, either by ejection by means of a pusher or by transport. animals on a conveyor belt or by tilting the entire container. The use of independent chutes increases operational safety and reduces the demands on the scrap yard. In addition, if a container for conveyed goods fails during use on the furnace head, its function can be taken over by another container. Another container can be brought into the charging area instead of the failed one. Possible faults on the container, in particular on the drive of the conveyor device, can then be serviced in a separate maintenance area.

Als Fördereinrichtung kommen neben einem Schieber, der elektrisch oder mit einem Fluidmotor angetrieben ist, auch Förderbänder sowie beliebig angetriebene Schwingrinnen zum Einsatz.In addition to a slide, which is driven electrically or with a fluid motor, conveyor belts and vibratory troughs of any type are used as the conveying device.

In einer vorteilhaften Weiterbildung wird der Schüttgutbehälter in einer Halte- rung abgelegt, die die Veränderung des Schüttgutwinkels in vertikaler und ggf. in horizontaler Lage bewirkt. Durch diese Kipp- und/oder Schwenkeinheit läßt sich der Schüttgutbehälter so einstellen, daß auch schwer zugängliche Bereiche im Ofenoberteil mit Schüttgut auffüllbar sind. Der Schüttgutbehälter selber ist dabei denkbar einfach aufgebaut.In an advantageous further development, the bulk goods container is placed in a holder which effects the change of the bulk goods angle in a vertical and possibly in a horizontal position. By means of this tilting and / or swiveling unit, the bulk goods container can be adjusted so that even hard-to-reach areas in the furnace top can be filled with bulk goods. The bulk container itself is very simple.

In einer besonderen Ausgestaltung ist eine Meß- und Regeleinrichtung zum Erfassen des Füllstandes im Ofenkopf vorgesehen, wobei über eine Rechenanlage eine Steuerung sowohl der Deckeldrehung wie auch der Austraggeschwindigkeit der Fördereinrichtung erfolgt.In a special embodiment, a measuring and regulating device is provided for detecting the fill level in the furnace head, control of both the lid rotation and the discharge speed of the conveying device being carried out via a computer system.

Die Schüttgutbehälter werden jeweils in Andockvorrichtungen abgelegt, die über angepaßte Dichtleisten ein umweltfreundliches Chargieren des metallurgischen Gefäßes gewährleisten. In einer vorteilhaften Weiterbildung der Erfindung ist diese Dichtleiste federnd gelagert. Die einzelnen Schüttgutbehälter können erfindungsgemäß in beliebiger Lage am Deckel angedockt werden.The bulk containers are each placed in docking devices, which ensure environmentally friendly charging of the metallurgical vessel via adapted sealing strips. In an advantageous development of the invention, this sealing strip is spring-mounted. According to the invention, the individual bulk goods containers can be docked in any position on the lid.

In einer ersten Ausgestaltung wird der Schüttgutbehälter diagonal auf dem kreisförmigen Deckel abgelegt, wobei der Schüttgutbehälter während des Chargierens nicht über den Deckelrand hinausragt.In a first embodiment, the bulk goods container is placed diagonally on the circular lid, the bulk goods container not protruding beyond the edge of the lid during charging.

In einer zweiten Ausgestaltung ragen nur die Schnauzen der Schüttgutbehälter zum Deckel, während ein Großteil der Behälterfläche den Deckelrand überragt. Bei dieser Ausgestaltung können deutlich mehr als nur ein Behälter am Ofenkopf angedockt werden. Hier bieten sich mindestens zwei Andockeinheiten an, da auf diese Weise ein ununterbrochenes kontinuierliches Chargieren möglich ist.In a second embodiment, only the snouts of the bulk material containers protrude toward the lid, while a large part of the container surface projects beyond the edge of the lid. With this configuration, significantly more than just one container can be docked on the furnace head. Here, at least two docking units are recommended, as this enables uninterrupted, continuous charging.

In einer weiteren vorteilhaften Ausgestaltung ist vorgesehen, mindestens drei Schüttgutbehälter am Ofenkopf andocken zu lassen, wobei die einzelnen Behälter in einer Linie geführt werden, die tangential zu der Mittellinie der Zugabeöffnungen geführt werden. Auf diese Weise ragen die einzelnen Behälter kaum über den Deckelrand hinaus und lassen dennoch ein kontinuierliches Befüllen des metallurgischen Gefäßes auch bei Ausfall eines Schüttgutbehälters zu.In a further advantageous embodiment, it is provided that at least three bulk goods containers dock onto the furnace head, the individual containers being guided in a line which are guided tangentially to the center line of the addition openings. In this way, the individual containers hardly protrude beyond the edge of the lid and still allow the metallurgical vessel to be filled continuously even if one bulk container fails.
