Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Verminderung der Wärmeabfuhr einer Stranggusskokille, insbesondere in deren Badspiegelbereich.The invention relates to a method and an apparatus for Reduction of heat dissipation of a continuous casting mold, especially in their bathroom mirror area.
In der Veröffentlichung "über den Zusammenhang zwischen Anfangserstarrung und Beschaffenheit der Strangoberfläche bei peritektisch erstarrenden Stählen" (Habilitationsschrift M. M. WoLff, Zürich 1996, Seiten 61 - 64) werden Bedeutung und Entwicklungstendenzen der Kokille beim Stranggussverfahren ausführlich behandelt. Dabei spielt insbesondere der Wärmestrom durch die Kokillenwand in deren Badspiegelbereich eine entscheidende Rolle für die Rissfreiheit der Strangschale.In the publication "on the connection between Initial solidification and condition of the strand surface peritectically solidifying steels "(habilitation thesis M. M. WoLff, Zurich 1996, pages 61 - 64) become meaning and Development trends of the mold in the continuous casting process treated in detail. In particular, the Heat flow through the mold wall in its bath level area a crucial role for the freedom from cracks Strand shell.
Es gibt mehrere Möglichkeiten, den Wärmestrom durch die Kokillenwand zu vermindern und dadurch deren Temperatur zu erhöhen. Bekannt sind verschiedene Möglichkeiten zum Aufbau von sogenannten "Hot-Top-Kokillen". Auf verschiedene Weise wird hierbei versucht, den Wärmestrom besonders im Bereich der Anfangserstarrung sowie darunter zu reduzieren und durch diese reduzierte Wärmeabfuhr die Rissneigung von schwingungsempfindlichen Stahlsorten (z. B. peritektische C-Stähle, hochlegierte rostfreie austenitische Stähle) zu verringern. Vorgeschlagen und zum Teil eingesetzt werden Kokillen, die
- ganz oder teilweise mit Materialien einer geringen Wärmeleitfähigkeit beschichtet sind (Ni, Chromcarbid, Zr20),
- einen keilförmigen Einsatz aus rostfreiem Stahl unterhalb der Kokillenoberfläche besitzen oder
- an der Oberfläche durch Rillen kontrolliert aufgerauht sind (Längsrillen parallel zur Gießrichtung, 45° zur Gießrichtung sowie gleichzeitig parallel und senkrecht zur Gießrichtung).
- fully or partially coated with materials with low thermal conductivity (Ni, chromium carbide, Zr 2 0),
- have a wedge-shaped insert made of stainless steel below the mold surface or
- are roughened in a controlled manner by grooves (longitudinal grooves parallel to the pouring direction, 45 ° to the pouring direction as well as parallel and perpendicular to the pouring direction).
Aber auch Kombinationen verschiedener Maßnahmen sind bekannt. Längsrillen parallel zur Gießrichtung können
- in einer Nickel-Beschichtung oder
- unterhalb einer Nickel-Beschichtung im Kupfer
- in a nickel coating or
- below a nickel coating in the copper
Auch die Kühlwassergeschwindigkeit und -temperatur sowie die Geometrie der Kühlwasserkanäle beeinflussen den Wärmestrom. Alle diese Maßnahmen müssen von vornherein konstruktiv festgelegt werden und sind nachträglich kaum zu ändern.The cooling water speed and temperature as well as the The geometry of the cooling water channels influence the heat flow. All of these measures must be constructive from the outset are determined and can hardly be changed afterwards.
Der Erfindung liegt die Aufgabe zugrunde, ein Mittel zur Verminderung der Wärmeabfuhr einer Stranggusskokille anzugeben, das vorzugsweise in deren Badspiegelbereich wirkt und ohne großen Aufwand angebracht bzw. erneuert werden kann.The invention has for its object a means for Reduction of the heat dissipation of a continuous casting mold specify that preferably acts in the bathroom mirror area and can be attached or replaced with little effort.
Die Aufgabe wird dadurch gelöst, dass der Wärmestrom zwischen der sich bildenden Strangschale und der Kokillen-Innenfläche durch eine Erhöhung des Wärmedurchgangswiderstandes als Folge des Aufrauhens der Kokillenoberfläche effektiv verringert und gleichzeitig vergleichmäßigt wird. Die auf diese Weise verminderte Wärmeabfuhr im Badspiegelbereich führt dazu, dass die sich bildende Strangschale länger dünn bleibt und von dem mit zunehmendem Abstand von dem Badspiegel steigenden ferrostatischen Druck gleichmäßiger an die Kupferplatte der Stranggusskokille angedrückt wird. Die Umwandlung der Deltain die Gammaphase erfolgt später, so dass sich das damit verbundene Schrumpfen der Strangschale geringer auswirkt. Durch den gleichmäßigeren Wärmeübergang treten außerdem in der Strangschale geringere Spannungen durch Temperaturunterschiede auf. Auf diese Weise wird die Entstehung von Rissen in der Strangschale unterbunden.The task is solved in that the heat flow between the strand shell that forms and the inner surface of the mold by increasing the thermal resistance as a result effectively roughening the mold surface and is equalized at the same time. That way reduced heat dissipation in the area of the bathroom mirror leads to the fact that the strand shell that forms remains thin longer and of that increasing with increasing distance from the bathroom mirror ferrostatic pressure more evenly on the copper plate of the Continuous casting mold is pressed. The conversion of the Deltain the gamma phase occurs later, so that's it associated shrinkage of the strand shell has less impact. The more even heat transfer also occurs in the Strand shell lower tensions due to temperature differences on. In this way, the formation of cracks in the Strand shell prevented.
Bei einer Vorrichtung zur Verminderung der Wärmeabfuhr einer Stranggusskokille, insbesondere in deren Badspiegelbereich ist die verminderte Wärmestromdichte zwischen der sich bildenden Strangschale und der Kokilleninnenfläche die Folge einer entsprechenden Makrostruktur dieser Innenfläche. Deren gezielte Rauhigkeit weist eine bestimmte Tiefe und Struktur auf.In a device for reducing heat dissipation Continuous casting mold, especially in the area of the bath level the reduced heat flow density between the formed Strand shell and the inner surface of the mold are the result of a corresponding macro structure of this inner surface. Their targeted roughness has a certain depth and structure on.
Eine vorteilhafte Ausbildung der Erfindung besteht darin, dass die Makrostruktur der Kokilleninnenfläche durch an sich bekannte Verfahren wie Shot Blast Texturing (SBT), Electric Discharge Texturing (EDT), Electron Beam Texturing (EBT), Laser Texturing (LT) oder durch eine gelochte Textur (GLT) oder durch andere Verfahren verwirklicht ist. Diese Aufrauhverfahren sind an sich bekannt und haben sich u. a. zum Aufrauhen von Arbeitswalzen für das Nachwalzen von Karosserieblechen bewährt. Die rauhe Kokilleninnenfläche hat bei Schmierung der Kokille mit Gießpulver den zusätzlichen Vorteil, dass die Schlacke des Gießpulvers intensiver an der Kokilleninnenwand haftet. Dadurch vermindert sich die Gefahr einer Ablösung der gesamten Schlackenschicht über größere Flächen. Dies hätte eine sprunghafte Änderung der örtlichen Strangschalentemperatur mit starken Temperaturspannungen soeir eine erhöhte Reibung zwischen Strangschale und Kokille zur Folge.An advantageous embodiment of the invention is that the macrostructure of the inner mold surface by itself known processes such as Shot Blast Texturing (SBT), Electric Discharge Texturing (EDT), Electron Beam Texturing (EBT), Laser Texturing (LT) or through a perforated texture (GLT) or is realized by other methods. This Roughening processes are known per se and have u. a. to the Roughening work rolls for re-rolling Body panels proven. The rough mold inner surface has if the mold is lubricated with casting powder, the additional one Advantage that the slag of the casting powder more intensely on the Mold inner wall adheres. This reduces the risk detachment of the entire slag layer over larger ones Surfaces. This would have caused a sudden change in local Strand shell temperature with strong temperature voltages soeir increased friction between the strand shell and the mold Episode.
Dadurch, dass die Oberflächentextur nur über einen Teil der Kokillenbreite angeordnet ist, können unterschiedliche Oberflächentemperaturen in Kokillenbreitenrichtung ausgeglichen werden.The fact that the surface texture covers only part of the Mold width is arranged can be different Surface temperatures in the direction of the mold width be balanced.
Dadurch, dass die Bearbeitungstiefe der Kokilleninnenfläche in Gießrichtung abnimmt, wird ein allmählicher übergang vom aufgerauhten zum glatten Teil der Kokille und damit vom gedrosselten zum ungedrosselten Wärmefluss erzielt.The fact that the machining depth of the mold inner surface in Direction decreases, there will be a gradual transition from roughened to the smooth part of the mold and thus from throttled to unthrottled heat flow achieved.
Ein weiterer Vorteil der erfindungsgemäßen Lösung besteht darin, dass die Makrostruktur auf einer Kokilleninnenfläche auch nachträglich oder, wenn verschlissen, als Reparatur Lösung angebracht werden kann. Wenn die Kokilleninnenfläche vor oder nach ihrer makroskopischen Bearbeitung mit einer Verschleißschutzschicht versehen ist, wird der Verschleiß der Makrostruktur vermindert und dadurch die Lebensdauer der Stranggusskokille erhöht. Another advantage of the solution according to the invention is in that the macrostructure on an inner mold surface also retrospectively or, if worn, as a repair solution can be attached. If the inner surface of the mold is in front of or after their macroscopic processing with a Wear protection layer is provided, the wear of the Macro structure diminishes and thereby the lifespan of the Continuous casting mold increased.

Durch die Modifikation der Anordnung der Oberflächentextur (T) gemäß den Figuren 1 bis 3 kann neben einer Variation von deren Bearbeitungstiefe die Wirkung der erfindungsgemäßen Lösung optimiert werden. Die Oberflächentextur kann nach Fig. 1 über die gesamte Breite der Kokille auf den unmittelbaren Bereich des Gießspiegels beschränkt bleiben, oder gemäß Fig. 2 oben beginnend bis zum unteren Ende der Kokille (K) weitergeführt werden, wobei die Bearbeitungstiefe in Gießrichtung (G) variierbar ist. Um das Auftreten unterschiedlicher Oberflächentemperaturen in Kokillenbreitenrichtung ausgleichen zu können, ist die Oberflächentextur nach Fig. 3 in Kokillenbreitenrichtung unterschiedlich gestaltet.By modifying the arrangement of the surface texture (T) 1 to 3, in addition to a variation of their Processing depth the effect of the solution according to the invention be optimized. The surface texture can be according to FIG the entire width of the mold on the immediate area of the mold level remain limited, or according to FIG. 2 above continued until the lower end of the mold (K) the machining depth in the casting direction (G) is variable. To the appearance of different Compensate surface temperatures in the direction of the mold width to be able to, the surface texture according to Fig. 3 in Mold width direction designed differently.
