Description

Die Erfindung betrifft eine Zelle zur Aufnahme eines metallurgischen Gefäßes, bei dessen Betrieb eine starke Rauchentwicklung auftrift, insbesondere eines Elektroofens und eines zugehörigen Abstichgefäßes, wobei an den Oberteil der Zelle eine Abzugsleitung anschließbar und ein Teil der Zellenwandung zum Einbringen des mittels eines Chargierkranes geförderten Gutes bewegbar ist.The invention relates to a cell for receiving a metallurgical vessel, in the operation of which a strong smoke development occurs, in particular an electric furnace and an associated tapping vessel, wherein a discharge line can be connected to the upper part of the cell and part of the cell wall can be moved for introducing the material conveyed by means of a charging crane is.

Bei metallurgischen Prozessen, wie der Herstellung von Stahl, entstehen beim Chargieren, beim Einschmelzen und beim Abstich Rauchgase, deren Sammlung und Ableitung oft mit.Schwierigkeiten verbunden ist.In metallurgical processes, such as the production of steel, flue gases are generated during charging, melting and tapping, the collection and discharge of which are often associated with difficulties.

Die während des Schmelzvorganges selbst anfallenden Rauchgase können meist ohne besonderen Aufwand durch eine am Schmelzgefäßdeckel angeschlossene Abzugseinrichtung abgeleitet werden. Wenn jedoch spezielle metallurgische Maßnahmen ergriffen werden, wie Einblasen von Kalkstaub oder Zugabe von Feinerz, können durch heftige Reaktionen Rauchschwaden austreten, die frei in die Halle strömen.The flue gases generated during the melting process can usually be discharged without any special effort through a fume cupboard connected to the melting vessel lid. However, if special metallurgical measures are taken, such as blowing lime dust or adding fine ore, vapors of smoke can escape due to violent reactions and flow freely into the hall.

Auch während des Chargierens und des Abgießens, wobei in ersterem Fall das metallurgische Gefäß ohne Deckel ist, kommt es zu starker Rauchgasentwicklung, wobei die Abgase frei in die Halle treten. Die Rauchgase müssen dann durch leistungsfähige Dachabsaugeeinrichtungen entfernt und zusammen mit der gesamten Hallenluft gefiltert werden. Die in die Halle frei austretenden Rauchgase stellen trotz der verwendeten Absaugeinrichtungen eine arge Belästigung des Bedienungspersonals dar und geben Anlaß zu übermäßigen Verschmutzungen und Korrosionsschäden.Also during charging and pouring, whereby in the former case the metallurgical vessel is without a lid, there is a strong development of smoke gas, with the exhaust gases entering the hall freely. The flue gases then have to be removed by powerful roof extraction systems and filtered together with the entire hall air. The flue gases escaping into the hall, in spite of the suction devices used, represent a serious nuisance to the operating personnel and give rise to excessive contamination and corrosion damage.

Man hat zur Verringerung der durch Rauchgase verursachten Schwierigkeiten schon vorgeschlagen, einen kippbaren Kleinkonverter allseitig mit einer Zelle zu umgeben, wobei die Zelle eine verschließbare öffnung zum Einbringen des Chargiergutes aufwies. Das zu chargierende Gut wurde dabei durch die Chargieröffnung mittels einer Chargierrutsche in die Konvertermündung eingebracht. Eine solche Zelle hat jedoch den Nachteil, daß sie nur für kleine Gefäße in Frage kommt und das Chargieren mittels eines Kranes nicht möglich ist.In order to reduce the difficulties caused by flue gases, it has already been proposed to surround a tiltable small converter with a cell on all sides, the cell having a closable opening for introducing the charging material. The goods to be charged were introduced into the converter mouth through the charging opening by means of a charging chute. However, such a cell has the disadvantage that it can only be used for small vessels and that charging by means of a crane is not possible.

Bei einer anderen bekannten Einrichtung, wie in der österreichischen Patentschrift Nr. 329.895 beschrieben, bei der das Schmelzgefäß durch einen Kran beschickt wird, sind Teile der Zellenwandung am Kran befestigt, wobei diese je nach Stellung des Kranes die Zelle entweder in der Chargierstellung oder in der Betriebsstellung abschließen. Diese Einrichtung hat den Nachteil, daß für jedes Gefäß ein eigener Chargierkran erforderlich ist und die Kranwege genau vorgegeben sind.In another known device, as described in Austrian Patent No. 329,895, in which the melting vessel is fed by a crane, parts of the cell wall are attached to the crane, which depending on the position of the crane, the cell either in the charging position or in the Complete operating position. This device has the disadvantage that a separate charging crane is required for each vessel and the crane paths are precisely specified.

Die Erfindung bezweckt die Vermeidung dieser geschilderten Nachteile und Schwierigkeiten und stellt sich die Aufgabe, Einrichtungen zur Aufnahme von metallurgischen Gefäßen zu schaffen, wobei ein Chargierkran für die Bedienung mehrerer Zellen, die jeweils ein metallurgisches Gefäß enthalten, verwendet werden kann und ein freier Rauchgasaustritt sowohl während des Chargierens als auch während des Schmelzens bzw. des Abstiches sicher vermieden wird; weiters sollen Vorkehrungen getroffen werden, um den Chargiervorgang entweder in Offenstellung oder Schließstellung der Zellendecke durchführen zu können, wobei das Chargieren mittels des Kranes gut beobachtbar und steuerbar ist.The invention aims to avoid these disadvantages and difficulties described and has as its object facilities for receiving metallurgical To create vessels, wherein a charging crane can be used to operate several cells, each containing a metallurgical vessel, and a free escape of flue gas is reliably avoided both during charging and during melting or tapping; furthermore, precautions are to be taken in order to be able to carry out the charging process either in the open position or in the closed position of the cell ceiling, the charging being easily observable and controllable by means of the crane.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Decke der Zelle zweiteilig ausgeführt ist und die beiden Teile zur Freigabe einer Chargieröffnung auseinander bewegbar sind, wobei während des Chargierens entweder die beiden Teile in Schließstellung zueinander zusammengeführt sind und der Oberteil der Zelle an einen Rauchabzug angeschlossen ist oder die beiden Teile in Offenstellung den Durchtritt der Rauchgase zu einer oberhalb der Chargieröffnung angeordneten Abzugshaube freigeben.This object is achieved in that the ceiling of the cell is made in two parts and the two parts can be moved apart to release a charging opening, wherein either the two parts are brought together in the closed position to each other during charging and the upper part of the cell is connected to a smoke vent or the two parts in the open position allow the passage of the flue gases to an extractor hood arranged above the charging opening.

Zweckmäßig sind die Deckenteile mit Vorderwandungsteilen der Zelle, die vorteilhaft bis unterhalb der Mündung des metallurgischen Gefäßes reichen, einstückig ausgebildet.The ceiling parts are expediently formed in one piece with front wall parts of the cell, which advantageously extend to below the mouth of the metallurgical vessel.

Hierbei können die Deckenteile einander ergänzende Ausnehmungen aufweisen, die in der Schließstellung eine Durchlaßöffnung für die Seile des Chargierkranes bilden.Here, the ceiling parts can have mutually complementary recesses which form a passage opening for the cables of the charging crane in the closed position.

Vorteilhaft ist an jedem der beiden Deckenteile ein Rauchabzugsstutzen vorgesehen, der in der Schließstellung an Abzugsleitungen anschließbar ist.On each of the two ceiling parts, a smoke outlet connection is advantageously provided, which can be connected to exhaust lines in the closed position.

Bei Anordnung einer Abzugshaube oberhalb der Chargieröffnung der Deckenteile ist ein Teil dieser Haube am Ende der-Kranbrücke befestigt und ein anderer, den ersten Teil zu geschlossener Haube ergänzender Teil ist an der Laufkatze des Chargierkranes befestigt und mit dieser verfahrbar.When a fume hood is arranged above the charging opening of the ceiling parts, part of this hood is attached to the end of the crane bridge and another part that complements the first part of the closed hood is attached to the trolley of the charging crane and can be moved with it.

In der Ausführungsform der Erfindung nach Fig. 1 umgibt eine Zelle 1 mit fester Rückwand 2 und zwei auf Rollen 3, 4 verfahrbaren Deckenteilen 5, 6 vollständig einen Elektroofen 7 mit Deckel 8 und ein Abstichgefäß 9. Die Deckenteile 5, 6 hängen einstückig mit Teilen 11 der Vorderwandung zusammen, welche letztere vorteilhaft bis unterhalb der Mündung 10 des Elektroofens 7 reichen. Die Deckenteile 5, 6 weisen jeweils eine Ausnehmung 12, 13 auf, die sich in Schließstellung zu einer öffnung 15 ergänzen. Weiters ist an jedem Deckenteil 5, 6 ein Rauchabzugsstutzen 18 befestigt, der an eine Abzugsleitung 19 anschließbar ist.In the embodiment of the invention according to FIG. 1, a cell 1 with a fixed rear wall 2 and two ceiling parts 5, 6 movable on rollers 3, 4 completely surrounds an electric furnace 7 with a lid 8 and a tapping vessel 9. The ceiling parts 5, 6 hang in one piece with parts 11 of the front wall together, the latter advantageously extending to below the mouth 10 of the electric furnace 7. The ceiling parts 5, 6 each have a recess 12, 13, which add up to an opening 15 in the closed position. Furthermore, a smoke exhaust connection 18 is attached to each ceiling part 5, 6 and can be connected to an exhaust line 19.

Zum Einbringen eines Chargierbehälters 14 in die Zelle werden die Deckenteile 5, 6 mit den Abzugsstutzen 18 seitlich verfahren, sodaß ein Chargierbehälter 14 leicht über den Elektroofen 7 in Chargierstellung gebracht werden kann. Dann werden die Deckenteile in Schließstellung gebracht, wobei die Seile 16 des Chargierkranes bzw. der Laufkatze 17 durch die öffnung 15 führen. Die Rauchabzugsstutzen 18 sind jetzt an der Abzugsleitung 19 angeschlossen, indem ihre beiden öffnungen fluchten. Das Chargiergut kann nun aus dem Chargierbehälter 14 in den Ofen 7 eingebracht werden, wobei die Rauchentwicklung nur in der Zelle stattfindet und die Rauchgase abgezogen werden. Nach Aufhören der Rauchentwicklung wird die Zelle geöffnet und der Chargierbehälter herausbewegt, worauf der Dackel 8 auf den Ofen 7 gebracht und die Zelle wieder geschlossen wird. Das Einschmelzen und Abgießen erfolgt bei geschlossener Zelle. Währenddessen im ser Kran frei in der Halle verfahrbar und kann bei amisren öfen zum Chargieren eingesetzt werden.In order to introduce a charging container 14 into the cell, the ceiling parts 5, 6 with the discharge nozzle 18 are moved laterally, so that a charging container 14 can be easily brought into charging position via the electric furnace 7. Then, the ceiling parts are brought into the closed position, wherein the cables 16 hargierkranes of the C or the trolley lead 17 through the opening 15 °. The smoke outlet connections 18 are now connected to the exhaust line 19 by aligning their two openings. The charge material can now be introduced from the charge container 14 into the furnace 7, the smoke development only taking place in the cell and the smoke gases being drawn off. After the smoke has stopped, the cell is opened and the charging container is moved out, whereupon the dachshund 8 is placed on the oven 7 and the cell is closed again. The melting and pouring takes place with the cell closed. In the meantime, it can be moved freely in the hall in the crane and can be used for charging in American furnaces.

Bei der Ausführungsform gemäß den Fig. 4 und 5 ist oberhalb der Zelle 1 eine zweiteilige Abzugshaube 20 am Chargierkran 21 angebracht und mit ihm verfahrbar. Rück und Seitenwände sowie die Decke der Haube 20 sind dest auf der Kranbrücke 22 montiert und mit Rauchabzugsstutzen 24 versehen, während die Vorderwand 23 der Haube an der Laufkatze 17 befestigt und mit dieser verfarrbar ist. Während des Chargierens befindet sich die Isufkatze 17 in der allseitig verschlossenen Haube 20. Bei dieser Ausführungsform ist es nicht notwendig, daß d e Deckenteile 5, 6 mit Ausnehmungen 12, 13 versehen sind, da die Zelle während des Chargiervorganges nicht geschlossen wird und der entstehende Rauch aus der ZE.le 1 in die Abzugshaube 20 steigt. Durch die Abzugs tutzen 24 strömt der Rauch in die gleiche Abzugsle tung 19, an die auch die Rauchabzugsstutzen 18 angescllossen sind. Die Haube 20 wird an die Abzugsleitung 19 auf die gleiche Art angeschlossen wie die Stutzen 18 an die Abzugsleitung 19, indem die Stutzen 24 mit öffnungen 25 in der Abzugsleitung 19 fluchten. Bei dieser Ausführungsform müssen die Stutzen 25 bzw. die unteren Rohrenden 26 der Abzugsleitung 19 wahlweise verschließbar sein, damit an den jeweils nicht in Funktion befindlichen Stutzen bzw. Rohrenden keine Falschluft angesaugt wird.In the embodiment according to FIGS. 4 and 5, a two-part extractor hood 20 is attached to the charging crane 21 above the cell 1 and can be moved with it. The rear and side walls as well as the cover of the hood 20 are at least mounted on the crane bridge 22 and provided with a smoke outlet connection 24, while the front wall 23 of the hood is fastened to the trolley 17 and can be fixed with it. During charging, the isufkatze 17 is in the hood 20 which is closed on all sides. In this embodiment, it is not necessary for the ceiling parts 5, 6 to be provided with recesses 12, 13, since the cell is not closed during the charging process and the smoke which arises from the Z E .le 1 rises into the hood 20. Through the exhaust nozzle 24, the smoke flows into the same device 19, to which the smoke outlet 18 are connected. The hood 20 is on the trigger Line 19 connected in the same way as the connector 18 to the exhaust line 19 by aligning the connector 24 with openings 25 in the exhaust line 19. In this embodiment, the connection piece 25 or the lower pipe ends 26 of the exhaust line 19 must be selectively closable, so that no false air is drawn in at the connection piece or pipe ends that are not in operation.

Die öffnungen der Abzugsleitung sind vorteilhaft mit Sperrorganen versehen, sodaß während des Einschmelzens und des Abstiches bei geschlossenen Deckenteilen 5, 6 die Öffnungen 25, und während des Chargierens bei offener Zelle, die Enden 26 der Abzugsleitung 19 geschlossen sind. Bei dieser Ausführungsform werden oftmalige öffnungs- und Schließvorgänge der Zelle während des Chargierens vermieden, und die Zeitaufwände bei wiederholtem Setzen von Schrottkörben verringert.The openings of the discharge line are advantageously provided with blocking elements, so that the openings 25 are closed during melting and tapping with closed ceiling parts 5, 6, and during charging with the cell open, the ends 26 of the discharge line 19 are closed. In this embodiment, frequent opening and closing operations of the cell during charging are avoided and the time required for repeated setting of scrap baskets is reduced.
