Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Auswechseln von Abstichrinnen an Schachtöfen.The invention relates to a device for replacing tapping troughs in shaft furnaces.
Der Abstich von Roheisen und Schlacke aus einem Hochofen erfolgt in periodischen Abständen. Je nach Menge des produzierten Roheisens ergeben sich acht bis zwölf Abstiche innerhalb von 24 Stunden. Beim Abstichvorgang werden Roheisen und Schlacke in einer sogenannten Hauptabstichrinne voneinander getrennt. Derartige Hauptabstichrinnen an Großhochöfen werden in neuerer Zeit mit großen Querschnitten ausgeführt. An die Hauptabstichrinne schließen sich in der Regel weitere Abstichrinnen und Kipprinnen für Roheisen (bis zur Übergabe in Pfannen oder Torpedowagen) und Schlacke an. Während die Schlacke aus der Hauptabstichrinne abgeführt wird, verbleibt das Roheisen zwischen den Abstichen in dieser Rinne.Pig iron and slag are tapped from a blast furnace at regular intervals. Depending on the amount of pig iron produced, there are eight to twelve taps within 24 hours. During the tapping process, pig iron and slag are separated from one another in a so-called main tapping channel. Such main tapping channels on large blast furnaces have recently been carried out with large cross sections. The main tapping trough is usually followed by other tapping troughs and tipping troughs for pig iron (up to delivery in pans or torpedo cars) and slag. While the slag is being removed from the main tapping channel, the pig iron remains in this channel between tapping.
Bei Abstichmengen an Roheisen von mehreren tausend Tonnen täglich unterliegt die feuerfeste Auskleidung der Hauptabstichrinne erheblichen mechanischen und thermischen Belastungen und demzufolge einem hohen Verschleiß. Aus diesem Grunde ist es erforderlich, die Auskleidung der Rinne in regelmäßigen Abständen zu reparieren bzw. komplett zu erneuern. Die Haltbarkeit von Abstichrinnen bis zur Zwischenreparatur liegt beispielsweise bei ca. 50000 t Roheisen, die komplette Erneuerung erfolgt nach einer Produktion von ca. 120000 - 130000 t Roheisen.With tapping quantities of pig iron of several thousand tons per day, the refractory lining of the main tapping channel is subject to considerable mechanical and thermal loads and consequently to a high level of wear. For this reason, it is necessary to repair or completely replace the gutter lining at regular intervals. The shelf life from tapping troughs to intermediate repairs is, for example, around 50,000 t of pig iron, and the complete replacement takes place after production of around 120,000 - 130,000 t of pig iron.
Bei Hochöfen mit mehr als einem Abstichloch werden die Arbeiten an der Abstichrinne vor Ort in der Gießhalle durchgeführt. Während dieser Reparaturzeit wird das Roheisen aus einem anderen Abstichloch - meist auch in einer zweiten Gießhalle - abgestochen, so daß sich dabei in der Regel keine oder nur geringfügige Einschränkungen des Betriebes ergeben.In the case of blast furnaces with more than one tap hole, work on the tapping channel is carried out on site in the casting hall. During this repair period it will Pig iron is tapped from another tap hole - usually also in a second casting hall - so that there are usually no or only minor restrictions on operation.
Ganz anders sieht es aber bei Hochöfen aus, die mit nur einem Abstichloch versehen sind. Derartige Hochöfen müssen für die Zeit der Reparatur bzw. Neuzustellung der feuerfesten Abstichrinnenauskleidung gedrosselt gefahren werden, bzw. bei längerer Zeit andauernden Arbeiten muß der Hochofen stillgesetzt werden.The situation is completely different for blast furnaces that have only one tap hole. Such blast furnaces must be throttled for the time of repair or relining of the fireproof tapping lining, or the blast furnace must be shut down for long periods of work.
Dieser Umstand führte zu Überlegungen, die Hauptabstichrinne mit Hilfe des Gießhallenkrans auszuwechseln. Dabei ging man auch so vor, daß man bei aus mehreren Abschnitten zusammengesetzten Hauptabstichrinnen einzelne erneuerungsbedürftige Abschnitte auf die beschriebene Weise auswechselte.This fact led to considerations to replace the main tapping channel with the help of the casting hall crane. The procedure was also such that, in the case of main tapping channels composed of several sections, individual sections in need of renovation were replaced in the manner described.
Wegen der zuvor bereits erwähnten großen Abmessungen der Hauptabstichrinne sind zum Auswechseln erhebliche Krankapazität erforderlich und selbstverständlich eine entsprechend schwere Ausführung der Gießhallen-Stahlkonstruktion. Ferner sind große freie Flächen in der Gießhalle notwendig, auf denen die ausgebauten Rinnenabschnitte für die Reparatur- und Neuzustellungsarbeiten gelagert werden können.Because of the large dimensions of the main tapping channel mentioned above, considerable crane capacity is required for replacement and, of course, a correspondingly heavy design of the steel casting structure. In addition, large free areas are required in the casting hall, on which the removed gutter sections can be stored for repair and relining work.
Bekannt ist auch eine Vorrichtung zum Auswechseln der Hauptabstichrinne eines Hochofens (DE-Patentanmeldung P 36 24 266.7), bei der vor dem Abstichloch des Hochofens auf dem Hüttenflur mindestens vier Hubelemente stationär oder nicht stationär angeordnet sind, die an Traversen angreifen, auf denen die Hauptabstichrinne aufliegt, wobei die auszuwechselnde Rinne auf ein auf dem Hüttenflur befindliches, insbesondere schienengebundenes, Transportmittel absenkbar ist und die neu zugestellte Rinne vom Transportmittel auf die Höhe der Gießbühne anhebbar ist, und daß die Hauptabstichrinne mit den Traversen mittels an der Stahlkonstruktion der Gießbühne angeordneter pneumatisch betätigter Haltearme gehalten wird.Also known is a device for changing the main tapping channel of a blast furnace (DE patent application P 36 24 266.7), in which at least four lifting elements are arranged in a stationary or non-stationary manner in front of the tapping hole of the blast furnace on the hut floor, which act on trusses on which the main tapping channel rests, the groove to be replaced on a the hut corridor located, in particular rail-bound, means of transport can be lowered and the newly delivered channel can be raised to the level of the casting platform by the means of transport, and that the main tapping channel is held with the crossbeams by means of pneumatically operated holding arms arranged on the steel structure of the casting platform.
Obgleich mit dieser bekannten Vorrichtung ein rascher Wechsel der Abstichrinne ermöglicht wird, bedarf es für die Installation doch einiger Vorbereitungsarbeiten, wie z.B. Erdarbeiten für die versenkbaren Hubelemente.Although this known device enables a rapid change of the tapping trough, some preparation work is required for the installation, e.g. Earthworks for the retractable lifting elements.
Aufgabe der Erfindung ist es, eine Auswechselvorrichtung für Abstichrinnen an Schachtöfen zu schaffen, bei deren Installation auf aufwendige Erd- und Fundamentarbeiten verzichtet werden kann und die sich auch nachträglich in vorhandene Hüttenwerksanlagen errichten läßt. Außerdem sollte eine solche Vorrichtung so konzipiert sein, daß sie auch transportabel ist, damit in einem Hüttenwerk mit mehreren Öfen nur eine Vorrichtung für das Auswechseln von Abstichrinnen angeschafft werden muß, zumal sich die Nutzungszeiten der Auswechselvorrichtung ohne weiteres abstimmen lassen.The object of the invention is to provide a replacement device for tapping troughs in shaft furnaces, the installation of which does not require expensive earthwork and foundation work and which can also be erected subsequently in existing metallurgical plants. In addition, such a device should be designed so that it is also portable, so that only one device for replacing tapping troughs has to be purchased in a metallurgical plant with several furnaces, especially since the times of use of the changing device can be easily coordinated.
Die Lösung dieser Aufgabe ist in Anspruch 1 angegeben. Vorteilhafte Einzelheiten sind in den Unteransprüchen aufgeführt.The solution to this problem is specified in
