Description
Die Erfindung betrifft eine Stranggießkokille und ein Verfahren zum senkrechten Stranggießen von Metallen nach den Oberbegriffen der Ansprüche 1 und 15.The invention relates to a continuous casting mold and a method for the vertical continuous casting of metals according to the preambles of
Eine solche kokille bzw. ein solches Verfahren sind allgemein bekannt.Such a mold or such a method are generally known.
Beim Stranggießen großer, rechteckiger Formate werden u.a. Stranggießkokillen verwendet, deren Kokilleneinsatz von einer Kühlvorrichtung umgeben ist.When continuously casting large, rectangular formats, Continuous casting molds are used, the mold insert of which is surrounded by a cooling device.
Die Verwendung von Stranggießkokillen der genannten Art beim Gießen von Bändern im Dickenbereich von etwa 6 - 30 mm ist nicht möglich, da insbesondere im Eckbereich des Kokilleneinsatzes die Kühlung zu stark ist, so daß im Eckbereich eine zu starke Vorerstarrung der Schmelze eintritt, während weiter im Zentrum des Kokilleneinsatzes die Schmelze noch flüssig ist, so daß insbesondere beim Anfahrvorgang die Gefahr des Durchbruchs des Stranges besteht.The use of continuous casting molds of the type mentioned when casting strips in the thickness range of about 6 - 30 mm is not possible, since in particular in the corner area of the mold insert the cooling is too strong, so that too much pre-solidification of the melt occurs in the corner area, while further in Center of the mold insert, the melt is still liquid, so that there is a risk of breakage of the strand, especially during the start-up process.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Stranggießkokille der genannten Art so auszubilden, daß eine gleichmäßige Kühlung des Stranges gewährleistet ist.The invention is therefore based on the object of designing a continuous casting mold of the type mentioned in such a way that uniform cooling of the strand is ensured.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kühlvorrichtung ausschließlich an den Breitseiten des Kokilleneinsatzes angeordnet ist und sich - ausgehend von der Kokillenunterkante UK - etwa bis auf 55 - 75 % der Höhe der Breitseite erstreckt und daß die Schmalseiten ungekühlt sind.The object is achieved in that the cooling device is arranged only on the broad sides of the mold insert and extends - starting from the lower mold edge UK - to about 55-75% of the height of the broad side and that the narrow sides are uncooled.
Es hat sich herausgestellt, daß durch die erfindungsgemäße Ausbildung der Stranggießkokille eine Vergleichmäßigung der Kühlung eintritt, so daß über den Querschnitt der Gießöffnung eine annähernd gleiche Höhe der Erstarrungsfront erzielt wird.It has been found that the inventive design of the continuous casting mold makes the cooling more uniform, so that the cross section of the Pour opening an approximately equal height of the solidification front is achieved.
Nach einer besonderen Ausführungsform der Erfindung erstreckt sich die Kühlvorrichtung etwa über die unteren zwei Drittel der Höhe der Breitseiten.According to a special embodiment of the invention, the cooling device extends approximately over the lower two thirds of the height of the broad sides.
Vorzugsweise ist jeder Breitseite des Kokilleneinsatzes ein Zweikanal-Kühlsystem zugeordnet. Dabei empfiehlt es sich, daß jeweils ein unterer, horizontal verlaufender Zuführkanal für die Kühlflüssigkeit mit einem oberen, ebenfalls horizontal verlaufenden Abführkanal über zum Kokilleneinsatz weisende Bohrungen in den Kanalwänden und vertikale Kühlkanäle in der Außenwandung der Breitseite des Kokilleneinsatzes in Verbindung steht.A two-channel cooling system is preferably assigned to each broad side of the mold insert. It is recommended that a lower, horizontally running supply channel for the cooling liquid is connected to an upper, also horizontally running discharge channel via bores in the channel walls facing the mold insert and vertical cooling channels in the outer wall of the broad side of the mold insert.
Aus Gründen der einfacheren Herstellung wird die Ausbildung des Kokilleneinsatzes aus zwei die Breitseite bildenden Platten, und zwei die Schmalseite bildenden Platten bevorzugt. Es werden Platten aus metallischen Werkstoffen verwendet.For reasons of simpler manufacture, it is preferred to form the mold insert from two plates forming the broad side and two plates forming the narrow side. Sheets made of metallic materials are used.
Um den Wärmefluß vom oberen, ungekühlten Bereich B zum unteren, gekühlten Bereich BK zu reduzieren, ist vorzugsweise in der Außenwandung der Breitseite des Kokilleneinsatzes jeweils ein horizontaler Trennschlitz angeordnet. Zur Steuerung des thermischen Verzugs des ungekühlten metallischen Bereichs B empfiehlt es sich, daß in den horizontalen Trennschlitz eine Leiste aus einem nichtmetallischen Werkstoff mit geringer Wärmeleitfähigkeit und relativ großem Ausdehnungskoeffizient eingepreßt ist.In order to reduce the heat flow from the upper, uncooled area B to the lower, cooled area B K , a horizontal separating slot is preferably arranged in the outer wall of the broad side of the mold insert. To control the thermal distortion of the uncooled metallic area B, it is recommended that in the horizontal separation slot is a bar made of a non-metallic material with low thermal conductivity and a relatively large coefficient of expansion.
Um das eventuelle Eindringen flüssiger Schmelze zu verhindern, sind die Bauteile des ungekühlten Bereichs B vorzugsweise in die Bauteile des gekühlten Bereichs BK eingepreßt. Wiederum aus Gründen der einfacheren Herstellung sind die Bauteile des ungekühlten Bereichs B von vier Platten oder zwei L-Formen gebildet.In order to prevent the possible penetration of liquid melt, the components of the uncooled area B are preferably pressed into the components of the cooled area B K. Again for the sake of simpler manufacture, the components of the uncooled area B are formed by four plates or two L-shapes.
Zur Verstärkung der Kühlung des aus der Kokille austretenden Stranges kann eine Sekundärkühlung mit Flachstrahldüsen nachgeschaltet sein.To increase the cooling of the strand emerging from the mold, secondary cooling with flat jet nozzles can be installed.
Die Erfindung betrifft gleichzeitig ein Verfahren zum Bandgießen unter Verwendung einer erfindungsgemäßen Stranggießkokille. Das Verfahren ist dadurch gekennzeichnet, daß der Gießspiegel während des Gießens etwa innerhalb des oberen, ungekühlten Drittels der Kokille gehalten wird. Dabei wird der Gießspiegel bevorzugt auf einer Höhe etwa 20 - 50 mm unterhalb der Kokillenoberkante OK gehalten.The invention also relates to a method for strip casting using a continuous casting mold according to the invention. The process is characterized in that the casting level is kept approximately within the upper, uncooled third of the mold during casting. The mold level is preferably held at a height of approximately 20-50 mm below the upper mold edge OK.

Die Stranggießkokille zum senkrechten Bandgießen nach den Figuren 1 bis 3 besteht im wesentlichen aus einem metallischen Kokilleneinsatz 1 (im folgenden kurz als "Einsatz" bezeichnet) und einer Kühlvorrichtung 2. Der Einsatz 1 ist aus Platten 3 bzw. 4 zusammengesetzt, die jeweils die Breitseiten bzw. Schmalseiten des Einsatzes 1 bilden. Die Platten 3, 4 werden durch nicht dargestellte Bolzen zusammengehalten. Es ergibt sich damit eine Gießöffnung 5 rechteckigen Querschnitts zur Aufnahme der Metallschmelze. Die Platten 3, 4 können beispielsweise aus Kupfer bestehen, weitere Möglichkeiten werden im folgenden besprochen.The continuous casting mold for vertical strip casting according to FIGS. 1 to 3 essentially consists of a metallic mold insert 1 (hereinafter referred to briefly as "insert") and a
Die Kühlvorrichtung 2 ist ausschließlich an den Breitseiten des Einsatzes 1 angeordnet, und zwar derart, daß sie sich - ausgehend von der Kokillenunterkante UK - etwa bis auf 55 - 75 % der Höhe der Breitseiten erstreckt, vorzugsweise über die unteren zwei Drittel der Höhe der Breitseiten. Der verbleibende obere Bereich der Breitseiten (also vorzugsweise das obere Drittel) sowie die Schmalseiten des Einsatzes 1 bleiben ungekühlt. Der untere, gekühlte Bereich der Breitseiten ist in Fig. 1 mit BK gekennzeichnet, der obere, ungekühlte Bereich mit B. Die in diesem Bereich B dargestellte Abstützung des Einsatzes 1 erfolgt lediglich aus Stabilitätsgründen.The
Die Kühlvorrichtung 2 besteht aus zwei identisch aufgebauten Zweikanal-Kühlsystemen, die an den Breitseiten (Platten 3) des Einsatzes 1 angeordnet sind, und zwar wird die Kühlflüssigkeit (insbesondere Wasser) durch einen unteren, horizontalen Zuführkanal 6 zugeleitet und durch einen oberen, horizontalen Abführkanal 7 abgeleitet. Vom Kanal 6 gelangt die Kühlflüssigkeit über zum Einsatz 1 weisende Bohrungen 8 in der Kanalwand 6′, über senkrechte Kühlkanäle 9 in der Außenwandung der Platte 3 und über zum Einsatz 1 weisende Bohrungen 10 in der Kanalwand 7′ in den Kanal 7. Die Strömungsrichtung der Kühlflüssigkeit ist jeweils durch Pfeile gekennzeichnet. In Fig. 3 bezeichnen die Pfeile den Zulauf der Kühlflüssigkeit zum Kanal 6 und den Ablauf der Kühlflüssigkeit aus dem Kanal 7.The
Um den Wärmefluß vom oberen, ungekühlten Bereich B der Breitseiten zum unteren, gekühlten Bereich BK zu reduzieren, ist auf der Außenseite der Platten 3 jeweils ein horizontaler Trennschlitz 11 angeordnet.In order to reduce the heat flow from the upper, uncooled area B of the broad sides to the lower, cooled area B K , a
Zur Durchführung des Gießverfahrens wird der Stranggießkokille Metallschmelze aus einer - nicht dargestellten - Verteilervorrichtung zugeführt. Der sich bildende Metallstrang 12 wird durch schematisch angedeutete Abzugsorgane 13 abgeführt. Während des Gießvorgangs wird der Gießspiegel 14 vorzugsweise in dem oberen (ungekühlten) Drittel der Stranggießkokille gehalten.To carry out the casting process, the continuous casting mold is supplied with molten metal from a distributor device (not shown).
