Description
Die Erfindung betrifft eine Kokille für eine Stranggießanlage mit einem formgebenden Kokillenkörper aus einem Material hoher Wärmeleitfähigkeit, wie Kupfer oder einer Kupferlegierung.The invention relates to a mold for a continuous caster with a shaping Mold body made of a material with high thermal conductivity, such as copper or a copper alloy.
Kokillen werden zur Herstellung von Vollprofilen in einem kontinuierlichen Gießprozeß verwendet. Die Kokille ist eines der wichtigsten Bauteile einer Stranggießanlage. In ihr beginnt die Erstarrung der Schmelze.Chill molds are used to produce full profiles in a continuous casting process used. The mold is one of the most important components of a continuous caster. The solidification of the melt begins in it.
Der prinzipielle Aufbau besteht in der Regel aus einer äußeren Stahlkonstruktion und dem eigentlichen formgebenden Teil der Kokille, dem Kokillenkörper. Der Kokillenkörper besteht heute fast ausschließlich aus Kupfer oder einer Kupferlegierung. Der Stahlmantel hat die Aufgabe, den Kokillenkörper zu positionieren und den zur Kühlung erforderlichen Wasserkreislauf sicherzustellen.The basic structure usually consists of an outer steel structure and the actual shaping part of the mold, the mold body. The mold body today consists almost exclusively of copper or a copper alloy. The steel jacket has the task of positioning the mold body and the Ensure cooling necessary water circuit.
Aus Gründen des Verschleißschutzes wird der Kokillenkörper mit einer inneren Beschichtung aus einem verschleißfesten Werkstoff, wie Nickel oder Chrom, versehen. Eine solche Stranggießkokille mit Verschleißschutzschicht geht beispielsweise aus der DE 31 42 196 C2 hervor. Hierdurch kann eine Verbesserung des Reibverhaltens und damit eine Erhöhung der Standzeit des Kokillenkörpers erreicht werden. For reasons of wear protection, the mold body is covered with an inner one Coating made of a wear-resistant material, such as nickel or chrome. Such a continuous casting mold with a wear protection layer works, for example from DE 31 42 196 C2. This can improve the friction behavior and thus an increase in the service life of the mold body can be achieved.
Infolge der Kühlung des flüssigen Stahls im Kokillenkörper erstarrt dieser in den Randbereichen unter Bildung einer in der Dicke permanent anwachsenden Strangschale. Hierbei kommt es zu einer Veränderung der Querschnittsgeometrie des Strangs durch Schrumpfung.As a result of the cooling of the liquid steel in the mold body, it solidifies in the Edge areas to form a strand shell that increases in thickness continuously. This changes the cross-sectional geometry of the Strands due to shrinkage.
Neben der Formgebung des Strangs hat der Kokillenkörper somit die wesentliche Aufgabe, durch eine kontinuierliche Wärmeabfuhr die Ausbildung einer ausreichend dicken widerstandsfähigen und fehlerfreien Strangschale zu gewährleisten.In addition to the shape of the strand, the mold body has the essential one Task, through continuous heat dissipation, the formation of an adequate to ensure thick, resistant and flawless strand shell.
Andererseits wirkt sich eine zu starke Wärmeabfuhr und damit Kühlung der Stahlschmelze zu Beginn des Erstarrungsvorgangs, insbesondere im Gießspiegelbereich, nachteilig auf die Oberflächenqualität des Strangs aus. Es kann dann zu Mikrorissen in der Oberfläche und Gefügefehlern kommen. Diese bilden sich insbesondere in Kantennähe des Kokillenkörpers aus. Ferner besteht die Gefahr, daß der Strang in dem sich verjüngenden Kokillenkörper verklemmt.On the other hand, excessive heat dissipation and thus cooling of the molten steel have an effect at the beginning of the solidification process, especially in the area of the mold level, disadvantageous on the surface quality of the strand. This can lead to micro cracks come in the surface and structural defects. These form especially in Edge of the mold body. There is also a risk that the strand in jammed the tapered mold body.
Um eine Reduzierung der Wärmeabfuhr im Gießspiegelbereich zu erreichen, ist es bekannt, die Schmelze im Kokillenkörper elektromagnetisch zu rühren. Dieses Verfahren ist jedoch vergleichsweise aufwendig. Desweiteren hat man versucht, eine Reduzierung der Wärmeabfuhr durch Vertikalschlitze in der Innenwand des Kokillenkörpers oder durch Einsätze aus feuerfestem Material zu erreichen.It is to achieve a reduction in heat dissipation in the area of the mold level known to electromagnetically stir the melt in the mold body. This However, the process is comparatively complex. Furthermore, one has tried one Reduction of heat dissipation through vertical slots in the inner wall of the mold body or by using inserts made of refractory material.
Ferner hat man Versuche mit dickeren inneren Verschleißschutzschichten angestellt. Durch die unterschiedlichen Wärmeausdehnungskoeffizienten der Werkstoffe von Kokillenkörpern, meist Kupfer, und der Verschleißschutzschicht, meist Nickel, kommt es jedoch zu erheblichen Spannungen in der Verschleißschutzschicht. Hierunter leidet die Haftung und es besteht die Gefahr der Ausbildung von Rissen. Tests have also been carried out with thicker inner wear protection layers. Due to the different thermal expansion coefficients of the materials of mold bodies, mostly copper, and the wear protection layer, mostly nickel, however, there is considerable tension in the wear protection layer. Below liability suffers and there is a risk of cracks forming.
Der Erfindung liegt daher ausgehend vom Stand der Technik die Aufgabe zugrunde, einen Kokillenkörper zu schaffen, bei dem die Wärmeabfuhr insbesondere im Gießspiegelbereich reduziert ist und eine bessere Strangqualität erzielt werden kann.Based on the prior art, the invention is therefore based on the object to create a mold body, in which the heat dissipation especially in the area of the mold level is reduced and a better strand quality can be achieved.
Die Lösung dieser Aufgabe besteht nach der Erfindung in den im kennzeichnenden
Teil des Anspruchs 1 aufgeführten Merkmalen.This object is achieved according to the invention in the characterizing
Features listed in
Kernpunkt der Erfindung bildet die Maßnahme, die Wärmeabfuhr im Kokillenkörper durch eine Beschichtung auf der Außenseite zu reduzieren. Die Beschichtung besteht aus einem Material mit einer gegenüber dem Werkstoff des Kokillenkörpers niedrigeren Wärmeleitfähigkeit. Daraus ergibt sich ein verfahrenstechnisch angestrebter reduzierter Wärmefluß im Gießspiegelbereich. Die hieraus resultierenden höheren Temperaturen wirken sich positiv auf die Qualität der Strangoberfläche und die Gefügequalität aus.The core of the invention is the measure, the heat dissipation in the mold body by reducing the coating on the outside. The coating is there from a material with a compared to the material of the mold body lower thermal conductivity. This results in a process engineering goal reduced heat flow in the area of the mold level. The resulting higher temperatures have a positive effect on the quality of the strand surface and the structure quality.
Bei dem Kokillenkorper kann es sich grundsätzlich um ein einteiliges Kokillenrohr oder um eine mehrteilige Gießform, beispielsweise eine Plattenkokille, handeln.The mold body can basically be a one-piece mold tube or a multi-part mold, for example a plate mold.
Auch wenn es grundsätzlich möglich ist, den Kokillenkörper auf der Außenseite
vollständig zu beschichten, wird die Beschichtung zweckmäßigerweise nur im Höhenbereich
des Gießspiegels aufgebracht, wie dies Anspruch 2 vorsieht. Auf diese
Weise kann gezielt im Gießspiegelbereich eine Reduzierung der Wärmeabfuhr realisiert
werden. Damit wird ein Überschreiten der Strangschalenfestigkeit vermieden.Even if it is basically possible, the mold body on the outside
To coat completely, the coating is expediently only in the height range
of the casting mirror applied, as provided for in
Die Dicke und Länge der äußeren Beschichtung wird auf die jeweiligen Gieß- und Anlagenparameter abgestimmt. The thickness and length of the outer coating is based on the particular casting and System parameters matched.
Nach den Merkmalen des Anspruchs 3 ist die Beschichtung nur auf einem Teil des Umfangs des Kokillenkörpers aufgebracht. Diese Maßnahme bietet sich insbesondere bei nicht rotationssymmetrischen Kokillenkörpern an. Bei Verstellkokillen kann es beispielsweise vorteilhaft sein, nur die Längsplatten mit einer äußeren Beschichtung zu versehen.According to the features of claim 3, the coating is only on part of the Applied circumference of the mold body. This measure is particularly useful with non-rotationally symmetrical mold bodies. With adjustable molds can it may be advantageous, for example, only the longitudinal plates with an outer coating to provide.
Durch die gezielte Beschichtung kann ein überproportionales Schrumpfen des Strangs in einzelnen Bereichen, beispielsweise in Eckbereichen, vermieden werden. So wird gewährleistet, daß der Wärmeübergang über den gesamten Umfang des Strangs annähernd gleichmäßig ist, so daß über den gesamten Querschnitt des Strangs eine in der Dicke gleichmäßig anwachsende Strangschale erzielt wird.The targeted coating can cause a disproportionate shrinkage of the Strands in individual areas, for example in corner areas, can be avoided. This ensures that the heat transfer over the entire circumference of the Strand is approximately uniform, so that over the entire cross section of the Strands a strand shell growing uniformly in thickness is achieved.
Eine qualitativ hochwertige und wirtschaftliche Beschichtung kann galvanisch aufgebracht
werden (Anspruch 4). Möglich ist es auch, die Beschichtung als thermische
Spritzschicht aufzubringen, wie dies Anspruch 5 vorsieht.A high quality and economical coating can be applied galvanically
be (claim 4). It is also possible to use the coating as a thermal
Apply spray layer, as provided for in
Gemäß den Merkmalen des Anspruchs 6 besteht die Beschichtung aus Nickel oder
einer Nickellegierung.According to the features of
Nickelwerkstoffe haben sich bereits als Werkstoff für die innere Verschleißschutzschicht bewährt. Häufig sind daher bei den Anwendern auch Möglichkeiten zum Vernickeln von Kokillenkörpern gegeben.Nickel materials have already become the material for the inner wear protection layer proven. Therefore, there are often options for users Nickel plating of mold bodies given.
Nickel hat gegenüber Kupfer eine mehr als vierfach geringere Wärmeleitfähigkeit. Dementsprechend kann durch eine äußere Beschichtung aus Nickel eine wirksame Reduzierung der Wärmeabfuhr und damit eine Erhöhung der Temperatur im Gießspiegelbereich bewirkt werden. Nickel has more than four times less thermal conductivity than copper. Accordingly, an outer coating made of nickel can be an effective one Reduction of heat dissipation and thus an increase in the temperature in the area of the mold level be effected.
Nickel kann sowohl als galvanischer Überzug als auch als Metall-Spritzüberzug aufgebracht werden. Hierbei kann der Kokillenkörper auf der Außenseite vollständig oder nur örtlich im Gießspiegelbereich beschichtet werden.Nickel can be applied as a galvanic coating or as a metal spray coating become. Here, the mold body can be completely on the outside or only be coated locally in the area of the mold level.
Nach den Merkmalen des Anspruchs 7 weist die Beschichtung eine in Gießrichtung
konstante Dicke auf. Die Übergänge in den Randbereichen der Beschichtung verlaufen
kontinuierlich. Auf diese Weise werden Spannungssprünge vermieden.According to the features of
Durch eine Beschichtung nach Anspruch 8, bei der die Dicke in Gießrichtung abnimmt, kann dem Schrumpfverhalten des zu vergießenden Werkstoffs gezielt Rechnung getragen werden. Hierbei nimmt die Wärmeabfuhrleistung in Gießrichtung zu. Auf diese Weise kann die effektive Abstimmung der für die Erstarrung zur Verfügung stehenden Kühlstrecke in der Kokille hinsichtlich des Schrumpfverhaltens des Strangs erfolgen.By a coating according to claim 8, in which the thickness decreases in the casting direction, can specifically take into account the shrinking behavior of the material to be cast be worn. Here, the heat dissipation performance increases in the casting direction. In this way, the effective tuning of the solidification is available standing cooling section in the mold with regard to the shrinking behavior of the Strangs take place.
Die Verringerung der Dicke der äußeren Beschichtung kann linear oder stufenförmig erfolgen.The reduction in the thickness of the outer coating can be linear or step-like respectively.
Da die Verschleißfestigkeit von Kupfer bzw. Kupferlegierungen, welche als Werkstoff für den Kokillenkörper zum Einsatz gelangen, relativ gering ist, kann es in Abhängigkeit vom Anwendungsfall zweckmäßig sein, den Kokillenkörper in bekannter Weise mit einer Innenbeschichtung zu versehen. Hier haben sich Innenbeschichtungen aus Nickel, Chrom oder überchromten Nickelauflagen bewährt.Since the wear resistance of copper or copper alloys, which is the material used for the mold body is relatively small, it can be dependent be useful from the application, the mold body in a known Way to provide an inner coating. Here are interior coatings Proven from nickel, chrome or chrome plating.
Die Erfindung ist nachfolgend anhand von in den Zeichnungen dargestellten Ausführungsbeispielen beschrieben. In den Figuren 1 bis 3 sind drei unterschiedliche Ausführungsformen eines Kokillenkörpers in Form eines Kokillenrohrs im vertikalen Längsschnitt dargestellt.

des Gießspiegels 7 eine Beschichtung 8 auf. Die Beschichtung 8 besteht aus
einem Werkstoff mit einer gegenüber dem Werkstoff des Kokillenrohrs 1 bzw. dem
Grundkörper 5 niedrigeren Wärmeleitfähigkeit. Insbesondere Nickel ist als Werkstoff
für die äußere Beschichtung 8 gut geeignet. Nickel kann sowohl als galvanischer
Überzug als auch als thermische Metall-Spritzschicht aufgebracht werden.On the
Die Beschichtung 8 reduziert den Wärmefluß und damit die Wärmeabfuhr des Kokillenrohrs
1 im Höhenbereich des Gießspiegels 7. Hieraus resultieren höhere
Wandtemperaturen in der Anfangsphase der Strangschalenausbildung. Dies führt zu
einer Verbesserung der Oberflächenqualität eines Stahlstrangs. Insbesondere Mikrorisse
in Kantennähe des Kokillenrohrs 1 können auf diese Weise vermieden werden.The coating 8 reduces the heat flow and thus the heat dissipation of the

Übergangsbereich 16.Another embodiment of a

Das Kokillenrohr 17 weist eine Beschichtung 18 an der Außenseite 19 auf, deren
Dicke D3 vom Stirnende 20 zum Fußende 21 linear abnimmt. Durch die Beschichtung
18 wird die Wärmeabfuhr im Kokillenrohr 17 reduziert. Der Wärmefluß nimmt
jedoch insgesamt vom Stirnende 20 des Kokillenrohrs 17 zum Fußende 21 hin zu.FIG. 3 shows a detail from a further variant of a
