Abstract
Description
Die Erfindung betrifft eine Horizontal-Stranggießanlage, insbesondere für das Gießen von Stahl, mit einer eine absperrbare Bodenöffnung aufweisenden Gießpfanne und einer warmgängigen Einrichtung, die mit mindestens zwei Kokillen in Verbindung steht.The invention relates to a horizontal continuous caster, in particular for the casting of steel, with a ladle having a lockable bottom opening and a warm-running device which is connected to at least two molds.
Bei Horizontal-Stranggießantagen, insbesondere für das Gießen von Stahl, erfolgt der Schmelzenfluß aus einer Pfanne in einen Verteiler, der mit einer oder mehreren Kokillen verbunden ist.
So ist aus EP 0 077 316 B1 eine Horizontal-Stranggießanlage bekannt, die ein Verteilergefäß zur Aufnahme der Schmelze und mindestens einer an dem Verteilergefäß befestigten Durchlaufkokille bekannt, wobei das Verteilergefäß gemeinsam mit der Kokille in einem mit einer ortsfesten Strangführungsbahn fluchtende Position bringbar bzw. aus dieser Position wegbewegbar ist.In the case of horizontal continuous casting plants, in particular for the casting of steel, the melt flows from a ladle into a distributor which is connected to one or more molds.
For example, EP 0 077 316 B1 discloses a horizontal continuous casting installation which has a distributor vessel for receiving the melt and at least one continuous mold attached to the distributor vessel, the distributor vessel being able to be brought into or out of alignment with the mold in a position aligned with a stationary strand guide track this position can be moved away.
Aus der EP-A-239 919 ist eine Horizontalstranggießanlage für mehrere Gießstränge bekannt, bei der das Verteilergefäß und pro Strangader eine Horizontalgießkokille mit jeweils einem Schieberverschluß auf einem Wagen angeordnet sind. In Betriebslage sind die Kokillen mit ortsfesten, zu den Strangadern ausgerichteten Böcken verbindbar.From EP-A-239 919 a horizontal continuous caster for several caster lines is known, in which the distributor vessel and one horizontal casting mold per strand are each arranged on a carriage with a slide closure. In the operating position, the molds can be connected to fixed trestles which are aligned with the strand veins.
Bei einer Mehrfach-Vertikal-Stranggießanlage gemäß der FR-A-24 53 696 werden die Kokillen über Verteiler gespeist, die von einem Zwischenspeichergefäß aus der Gießpfanne versorgt werden. Hierbei soll ein Auswechseln der Gießpfanne ohne Veränderung des Gießspiegels in den Verteilern möglich sein.In a multiple vertical continuous caster according to FR-A-24 53 696, the molds are fed via distributors which are supplied from the ladle by an intermediate storage vessel. It should be possible to replace the ladle without changing the pouring level in the distributors.
Da die Kokille am Verteilergefäß befestigt ist, ist der Verteiler bei einem Wechsel der Kokille mit auszutauschen. Das hat zur Folge, daß die Produktion unterbrochen wird.
Aus der Schrift DE OS 25 25 449 ist eine Stranggießanlage zum waagerechten Gießen und Abziehen eines Stranges bzw. von Strängen bekannt, das ein mit einer Kokille verbundene Vorkammer aufweist. Diese mit einer oder mehreren Kokillen versehene Vorkammer ist mit einer Wechseleinrichtung verbunden, mit welcher die Vorkammer in vorpositionierter Lage montierbar und von der Betriebsstellung in eine Reservestellung und zurück bewegbar ist.
Ohne Störung des Betriebes kann eine Vorkammer auf einem Lagertisch montiert, justiert und vorbeheizt werden. Die im Betrieb befindliche Vorkammer, üblicherweise Verteiler genannt, nimmt aus der Pfanne die metallische Schmelze auf und stellt die Verbindung zur Kokille her. Mit der aus dieser Schrift bekannten Wechseleinrichtung wird zwar mit aufwendigen Mitteln die Wechselzeit einer VorKammer (Verteiler) verkürzt, dennoch kommt es bei jedem Wechsel zu einer Betriebsunterbrechung.Since the mold is attached to the distributor vessel, the distributor must also be replaced when changing the mold. As a result, production is interrupted.
From the document DE OS 25 25 449 a continuous casting plant for the horizontal casting and drawing off of a strand or strands is known, which has a pre-chamber connected to a mold. This pre-chamber, which is provided with one or more molds, is connected to a changing device with which the pre-chamber can be mounted in a pre-positioned position and moved from the operating position to a reserve position and back.
A pre-chamber can be mounted, adjusted and preheated on a storage table without disrupting operation. The pre-chamber in operation, usually called the distributor, picks up the metallic melt from the pan and establishes the connection to the mold. With the exchange device known from this document, the exchange time of an antechamber (distributor) is shortened with complex means, but there is an interruption in operation with each exchange.
Die Erfindung hat sich das Ziel gesetzt, mit einfachen konstruktiven Mitteln eine mehrere Stränge aufweisende Horizontal-Stranggießanlage zu schaffen, bei der ohne Produktionsunterbrechung ein Kokillenwechsel und/oder ein Analysenwechsel bei der Schmelze mit minimaler Mischanalyse möglich ist.
Die Erfindung erreicht dieses Ziel durch die kennzeichnenden Merkmale des Anspruchs 1.
Bei den herkömmlichen Stranggießanlagen übernimmt der Verteiler die Funktion eines Speichers und darüber hinaus die Druckvorgabe beim Zufluß zur Kokille durch den Pegel der Schmelze. Die Größe des Verteilers wird bestimmt durch den Gießquerschnitt und damit der Gießleistung und der erforderlichen Zeit des Pfannenwechsels.The invention has set itself the goal of using simple constructional means to create a horizontal continuous casting installation having a plurality of strands, in which a mold change and / or an analysis change in the melt is possible with minimal mixing analysis without interrupting production.
The invention achieves this aim by the characterizing features of claim 1.
In the case of conventional continuous casting plants, the distributor takes on the function of a store and, moreover, the pressure specification when it flows to the mold through the level of the melt. The size of the distributor is determined by the casting cross-section and thus the casting performance and the time required for changing the ladle.
Bei der vorgeschlagenen Stranggießführungs- und speichereinrichtung, die aus einer Verteilerrinne und aus den wannenförmigen Behältern sog. Feedern besteht, werden diese Funktionen getrennt. Hier dient der Verteiler der Speicherung der Schmelze, die einzelnen Feeder, übernehmen die Funktionen des Vordruckes einlaufseitig zur Kokille. Dies eröffnet die Möglichkeit ,den Verteiler konstruktiv einfach auszuführen und insbesondere keine Rücksicht auf eine bestimmte Bauhöhe zu nehmen. Die einzelnen mit den Kokillen verbundenen Feeder weisen dabei eine Bauform auf, die bei möglichst geringem Schmelzenvolumen die exakte Einhaltung des Schmelzenspiegels und damit des Einlaufvordruckes zur Kokille zulassen. Die Stahlwerker werden in die Lage versetzt, bei laufendem Betrieb bei einzelnen Strängen einen Formatwechsel durchzuführen.
Auch bei Störungen in einzelnen Strängen lassen sich diese ohne Beeinflussung der Nachbarstränge absperren und wechseln.These functions are separated in the proposed continuous casting guide and storage device, which consists of a distribution channel and the trough-shaped containers of so-called feeders. Here the distributor serves to store the melt, the individual feeders take over the functions of the pre-pressure on the inlet side to the mold. This opens up the possibility of constructing the distributor in a structurally simple manner and, in particular, not taking into account a certain overall height. The individual feeders connected to the molds have a design that allows the melt level and thus the inlet admission pressure to the mold to be exactly maintained with the smallest possible melt volume. The steelworkers are enabled to change the format of individual strands during operation.
Even in the event of faults in individual lines, these can be shut off and changed without influencing the neighboring lines.
Weiterhin ist ein Qualitätswechsel der Schmelze mit äußerst geringen Mischverlusten möglich, da hier das Feeder-Volumen ausschlaggebend ist, welches in der erfindungsgemäßen Ausgestaltung minimiert wird.
Darüber hinaus ist ein Wechsel der Verteilerrinne ohne Gießunterbrechung möglich, da beim Wechsel der Rinne die Feeder mit Schmelze belegt sind. Diese einfache, ein geringes Bauvolumen aufweisende Verteilerrinne läßt sich schnell und einfach gegen eine neue vorbereitete Rinne austauschen.Furthermore, a change in the quality of the melt is possible with extremely low mixing losses, since here the feeder volume is decisive, which is minimized in the embodiment according to the invention.
In addition, the distributor channel can be changed without interrupting the casting process, since the feeders are coated with melt when the channel is changed. This simple, low-volume distribution channel can be quickly and easily replaced with a new prepared channel.
Bei der Verbindung Kokille-Verteilergefäß kommt es in der Gefäßwandung zu Spannungen, da die Kokillen starr befestigt sind und die einzelnen Kokillenanbindungen an die voluminösen ein hohes Flüssigstahl- und damit ein großes Wärmevolumen aufnehmenden Verteilerrinnen bei den herkömmlichen Anlagen üblicherweise weit auseinanderliegen. Bei der vorliegenden Feederlösung mit den umabhängigen, ein geringes Volumen aufweisenden Gefäßen ist dieses Problem beherrschbar.When the mold-distributor vessel is connected, there is tension in the wall of the vessel, since the molds are rigidly attached and the individual mold connections to the voluminous distributor troughs, which absorb a large amount of heat and thus a large heat volume, are usually far apart in conventional systems. With the present feeder solution with the independent, low-volume vessels, this problem can be mastered.
