Description
Die Erfindung betrifft eine Einrichtung zum Auffangen und Ableiten von beim Chargieren bzw. Abgießen von metallurgischen Gefäßen entstehenden Abgasen in einem Stahlwerk, wobei das zu chargierende bzw. abgegossene Gut mit einem mittels eines Kranes verfahrbaren Behälter in die bzw. aus der Betriebsstellung gebracht wird.The invention relates to a device for collecting and discharging exhaust gases generated during charging or pouring of metallurgical vessels in a steel mill, the material to be charged or poured being brought into or out of the operating position with a container that can be moved by means of a crane.
Bei der Erzeugung von Stahl kommt es an verschiedenen Stellen des Stahlwerkes zu starker Rauchentwicklung, z.B. beim Umleeren von Roheisen aus einem Torpedomischer in Pfannen, beim Einfüllen von Roheisen in den Roheisenmischer und beim Beschicken von Pfannen aus dem Roheisenmischer. Weiters entsteht eine starke Rauchentwicklung bei den Chargiervorgängen von Schrott und Roheisen in den Konverter. Bei diesen Chargier-, Umleer- und Abgießvorgängen hängen die das schmelzflüssige Gut enthaltenden Behälter mittels eines Krangehänges an einem Kran, und es ist schwierig, an den verschiedenen Stellen, an denen die Rauchentwicklung stattfindet, unmittelbar wirksame Absaugeinrichtungen vorzusehen. Die Entstaubungsprobleme beim Chargieren und Abstechen metallurgischer Gefäße, insbesondere eines Roheisenmischers oder eines Elektroofens, sind nicht befriedigend gelöst. Bei der in letzter Zeit häufig angewandten Methode der Dachabsaugung werden oberhalb der rauchentwickelnden Aggregate, an den höchsten Stellen im Dach der Stahlwerkshalle Absaugeinrichtungen angeordnet. Durch diese wird aber nicht nur der Rauch, sondern auch die Hallenluft abgesaugt und die Filteranlage zusätzlich belastet. Da der Abstand zwischen einem rauchentwicklenden Aggregat und den Absaugeinrichtungen im Hallendach sehr groß ist, besteht auch die Gefahr, daß bei geringerem Auftrieb der Rauch- bzw. Staubteilchen diese vom Saugstrom nicht erfaßt werden und wieder absinken. Deshalb müssen die Saugzuganlagen leistungsmäßig sehr stark ausgelegt werden, was hohe Investitionskosten verursacht.When steel is produced, there is a lot of smoke at various points in the steelworks, e.g. when emptying pig iron from a Torpedo mixer in pans, when pouring pig iron into the pig iron mixer and when loading pans from the pig iron mixer. Furthermore, creating a strong Rauchentwicklun g at the Chargiervorgängen of scrap and pig iron in the converter. In these charging, emptying and pouring operations, the containers containing the molten material hang from a crane by means of a crane hanger, and it is difficult to provide effective suction devices at the various places where the smoke development takes place. The dust removal problems when charging and tapping metallurgical vessels, in particular a pig iron mixer or an electric furnace, have not been satisfactorily solved. With the method that has been used recently the D achabsaugung be disposed above the suction smoke developing units, at the highest points in the roof of the steelworks hall. Through this, not only the smoke is extracted, but also the hall air and the filter system is additionally loaded. Since the distance between a smoke-generating unit and the suction devices in the hall roof is very large, there is also the risk that, with less buoyancy of the smoke or dust particles, they will not be caught by the suction flow and will sink again. Therefore, the suction systems have to be very powerful, which causes high investment costs.
Bei Verwendung von Abzugshauben, die direkt über einem rauchentwickelnden Aggregat angeordnet sind, ist die Schwierigkeit gegeben, daß diese wegen des beim Chargieren notwendigen Heranfahrens des Kranes zum metallurgischen Gefäß, z.B. Konverter, nur bis zu einer bestimmten Größe ausgelegt werden können. Sie sind für die vollständige Erfassung des entstehenden Rauches zu klein, weshalb ein Teil der Abgase an der Abzugshaube vorbei entweicht.When using fume hoods which are arranged directly above a smoke-generating unit, there is the difficulty that these are due to the need to move the crane towards the metallurgical vessel, e.g. Converter, can only be designed up to a certain size. They are too small for the complete detection of the smoke, which is why some of the exhaust gases escape past the extractor hood.
Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, eine Einrichtung zu schaffen, mit der die bei Erzeugung von Stahl entstehenden Gase nahezu zur Gänze erfaßt werden, wobei diese Einrichtung vorteilhaft für eine Mehrzahl von Arbeitsständen, an denen Rauch entsteht, eingesetzt werden kann, der Hallenkran jedoch ungehindert von stationären Einbauten in die verschiedenen Betriebsstellungen verfahrbar ist.The invention aims at avoiding these disadvantages and difficulties and has as its object to create a device with which the gases generated during the production of steel are almost completely detected, this device being advantageous for a plurality of work stations where smoke is generated, can be used, but the hall crane can be moved unhindered by stationary installations in the different operating positions.
Diese Aufgabe wird bei einer Einrichtung der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, daß die Kranlaufkatze mit einer Abzugshaube eine verfahrbare Einheit bildet, wobei die Abzugshaube in der Betriebsstellung den Behälter und die Mündung des metallurgischen Gefäßes überdeckt und an einen Kamin anschließt.This object is achieved according to the invention in a device of the type mentioned at the outset in that the crane trolley forms a movable unit with an extractor hood, the extractor hood in the operating position covers the container and the mouth of the metallurgical vessel and connects to a chimney.
Nach einer bevorzugten Ausführungsform ist die aus Kranlaufkatze und Abzugshaube bestehende Einheit zwischen mindestens zwei Betriebsstellungen verfahrbar, z.B. zwischen der Einfüllposition und Ausgießposition eines metallurgischen Gefäßes, wie eines Roheisenmischers, wobei in jeder Betriebsstellung die Abzugshaube an einen Kamin anschließbar ist.According to a preferred embodiment, the unit consisting of crane trolley and extractor hood can be moved between at least two operating positions, e.g. between the filling position and pouring position of a metallurgical vessel, such as a pig iron mixer, the extractor hood being connectable to a chimney in each operating position.
Vorteilhaft ist die öffnung im Abzugskamin erweitert und vorzugsweise in Fahrtrichtung der Kranlaufkatze verlängert, wobei Korrekturbewegungen der Kranlaufkatze ohne Beeinträchtigung des Gasabzuges durchführbar sind. Hierfür ist es auch zweckmäßig, daß an der Anschlußöffnung der Abzugshaube ein in Laufrichtung der Kranlaufkatze verlängerter Flansch befestigt ist. Mit dieser Ausbildung wird bei Korrekturbewegungen das Ansaugen von Falschluft vermieden.The opening in the fume cupboard is advantageously widened and preferably lengthened in the direction of travel of the crane trolley, corrective movements of the crane trolley being able to be carried out without impairing the gas discharge. For this purpose, it is also expedient that a flange which is extended in the running direction of the crane trolley is fastened to the connection opening of the extractor hood. With this training, the sucking in of false air is avoided during corrective movements.

Die Kaminstutzen besitzen einen trichterförmig erweiterten Teil 11. Der Anschlußteil der Haube 6 ist mit einem in Laufrichtung der Kranlaufkatze verlängerten Flansch 12 ausgebildet, wie deutlicher in den Fig. 5, 6 und. 6 a ersichtlich ist. Nach Einfahren der Abzugshaube in die Betriebsstellung sind Korrekturbewegungen in der Fahrtlängsrichtung möglich, während welcher infolge der länglichen Ausbildung des Flansches 12 die Dichtung erhalten bleibt.

In der Betriebsstellung wird die an die Abzugshaube 6 anschließende öffnung eines Kaminstutzens 9 geöffnet, während vorteilhaft alle anderen Kaminstutzen geschlossen bleiben, um eine Ansaugung von Falschluft in die Filteranlage zu vermeiden. Die Abzugshaube kann, wie in den Fig. 1 bis 4 dargestellt ist, mit an ihrem unteren Rand seitlich angefügten Leitblechen 13 und einem Kettenvorhang 14 ausgestattet sein, um eine verbesserte Rauchführung zu bewirken. Die Leitbleche sind zwischen den Brückenträgern 4, 4' nach unten geführt. Weiters kann an der Unterseite ein Maschengitter 15 vorgesehen sein, um ein Durchschlagen von Flammen zu verhindern.In the operating position, the opening of a
