Description
Die Erfindung betrifft eine Plattenkokille zur Erzeugung von Strängen aus Stahl.The invention relates to a plate mold for producing strands of steel.
Aus DE 24 15 224 C3 ist eine Plattenkokille für Brammen bekannt, deren Kokillenwände Kühlkammern besitzen, die bestimmte Kühlbereiche umfassen. An die Wasserzu- und - abflußleitungen der Breitseiten sind Meßglieder zur Bestimmung der abgeführten Wärmemenge bzw. der Kühlleistungen angeschlossen. Weiterhin wird in den Meßgliedern gleichzeitig ein Durchschnittswert der Kühlleistung der Kühlkammern gebildet, welcher einem Durchschnittsbildner zugeleitet wird, mit dem die Konizität der Schmalseiten gesteuert werden kann.DE 24 15 224 C3 discloses a plate mold for slabs, the mold walls of which Have cooling chambers that include certain cooling areas. To the water supply and - Drain lines of the broad sides are measuring elements for determining the discharged Heat quantity or the cooling capacities connected. Furthermore, in the measuring elements at the same time an average value of the cooling capacity of the cooling chambers is formed, which is fed to an average former with which the conicity of the narrow sides is controlled can be.
Aus DE 41 17 073 C2 ist es bekannt, mit Hilfe einer kalorimetrischen Messung an eine Brammenkokille, insbesondere einer rechteckigen oder bombierten Dünnbrammenkokille, den integralen und spezifischen Wärmetransport an jeder einzelnen Kupferplatte zu bestimmen. Ein "on-line"-Vergleich der spezifischen Wärmeströme von der dem Stahl zugewandten Kupferplattenseite, den sogenannten hot face, zur wassergekühlten Seite speziell der Schmalseiten, mit denen der zwei Breitseiten ermöglicht die Regelung der Schmalseitenkonizitäten unabhängig von den im einzelnen gewählten Gießparametern.From DE 41 17 073 C2 it is known to calorimetrically measure one Slab mold, in particular a rectangular or cambered thin slab mold, the integral and specific heat transfer to each individual copper plate determine. An "on-line" comparison of the specific heat flows from that of the steel facing copper plate side, the so-called hot face, to the water-cooled side especially the narrow sides, with which the two broad sides enables the regulation of the Narrow-side conicity regardless of the individually selected casting parameters.
In nachteiliger Weise kann bei den o. g. Plattenkokillen keine differenzierte Aussage über den partiellen Wärmestrom über die Kokillenbreite gemacht werden. Darüber hinaus sind die eingesetzten Temperaturfühler für ein sicheres Gießen bei Gießgeschwindigkeiten oberhalb von 1,5 m/min nicht geeignet.Adversely, the above-mentioned. Plate molds no differentiated statement about the partial heat flow across the mold width. In addition, the temperature sensor used for safe casting at casting speeds above of 1.5 m / min is not suitable.
Die Erfindung hat sich daher das Ziel gesetzt, eine gattungsgemäße Plattenkokille für Gießgeschwindigkeit zwischen 1,5 und 8 m/min zu schaffen, die eine einfache und sichere Temperaturführung einschließlich der Breitseitenmitte im Bereich des Tauchausgusses ermöglicht. The invention has therefore set itself the goal of a generic plate mold for Casting speed between 1.5 and 8 m / min to create an easy and safe Temperature control including the middle of the broadside in the area of the immersion spout enables.
Diese Aufgabe wird gelöst durch eine Plattenkokille, mit wassergekühlten Schmalseitenwänden, die zwischen Breitseitenwänden einklemmbar sind, wobei die Breitseitenwänden mindestens drei nebeneinander liegende und voneinander unabhängige Kühlsegmente aufweisen, symmetrisch zur Mittenachse der Kokille aufgeteilt sind und im Bereich der Kokillenmündung gesonderte Anschlüsse zur unabhängigen Zufuhr eines flüssigen Kühlmediums aufweisen, und mit Einrichtungen zum Verstellen des von den Schmal- und Breitseitenwänden gebildeten Formhohlraums an verschiedene Strangabmessungen sowie des Gießkonus, und mit einer Oszillationseinrichtung, und mit in der dem Strang zugewandten Wandung der Kammern vorgesehenen Temperaturfühlern, mit denen mindestens die Temperaturdifferenzen zwischen den einzelnen Kammern bzw. Zonen erfaßt werden und Temperaturfühlern, die in den Kühlmittelzu - bzw. Ableitungen angeordnet sind, wobei die Temperaturfühler wie auch die Temperaturfühler mit einem Regler in Verbindung stehen, der über einen Aktuator die Konizität der Schmalseiten steuert und/oder den Abgleich der spezifischen Wärmeströme pro Kammer bzw. Zone zueinander durch Veränderung der Oszillationsparameter durchführt.This task is solved by a plate mold with water-cooled Narrow side walls that can be clamped between broad side walls, the Broad side walls at least three side by side and independent of each other Have cooling segments, are divided symmetrically to the center axis of the mold and in Separate connections for the independent supply of a Have liquid cooling medium, and with means for adjusting the of the Narrow and wide side walls formed mold cavity to different Strand dimensions and the casting cone, and with an oscillation device, and with in the wall sensors of the chambers facing the strand, with which at least the temperature differences between the individual chambers or Zones are detected and temperature sensors in the coolant supply and discharge lines are arranged, the temperature sensors as well as the temperature sensors with a Connect controller, which controls the taper of the narrow sides via an actuator and / or the comparison of the specific heat flows per chamber or zone to one another by changing the oscillation parameters.
Durch diese Anordnung kann eine differenzierte Aussage über den partiellen Wärmestrom über die Kokillenbreite gemacht werden. Hiermit werden die Wärmestromdifferenzen über die Brammenbreite berücksichtigt, so daß die zugrunde liegenden Messungen sich integral über die Kokillenbreite und die Kokillenhöhe partiell erfassen lassen. Um für das sichere Gießen von Brammen und speziell von Dünnbrammen besonders bei Gießgeschwindigkeiten zwischen 1,5 und 8 m/min ist die Kenntnis des spezifischen Wärmeübergangs der Breitseiten besonders in der Brammenmitte von Bedeutung. Hiermit wird die Möglichkeit eröffnet, im Bereich des Tauchausgusses im Vergleich zum Rest der Breitseiten und zu den Schmalseiten eine gleichförmige Kühlleistung über die gesamte Kokillenbreitseite und damit über die gesamte Brammenbreite zu erreichen und Störungen zu vermeiden, die durch folgende Einflüsse hervorgerufen werden:
- strömungsschattenbedingt durch den Tauchausguß
- relativer Schlackenmangel und damit Schmierfilmdicke durch verringerte aktive Dicke über die Brammenbreite für die Erschmelzung von Gießpulver zu Gießschlacke
- hohe Membranwirkung der Strangschale in der Brammenmitte
- Strömungssymmetrie bezogen auf die Mittenachse des Stranges in Gießrichtung
- Turbulenzen des Gießspiegels über die Brammenbreite.
- flow shadow due to the diving spout
- relative lack of slag and thus lubricating film thickness due to reduced active thickness across the slab width for the melting of casting powder to pouring slag
- high membrane effect of the strand shell in the middle of the slab
- Flow symmetry related to the central axis of the strand in the casting direction
- Turbulence of the mold level across the slab width.
Zur Bestimmung einer differenzierten spezifischen Wärmestromdichte über die Breite der Kokille und im Bereich der Schmalseiten bzw. über die Bramme und damit der Möglichkeit, Einfluß auf ein sicheres Gießen zu nehmen, werden Aktuatoren eingesetzt zur Steuerung:
- der Konizität
- der Tauchausgußposition und somit der Eintauchtiefe während des Gießens
- die Beurteilung der eventuell bedingten Strömungsänderung im Tauchausguß z.B. durch Oxidablagerungen.
- of taper
- the immersion pouring position and thus the immersion depth during casting
- the assessment of the possible change in flow in the immersion nozzle, for example due to oxide deposits.
Darüber hinaus besteht die Möglichkeit, sowohl den Tauchausguß wie auch die Kokillenform einzeln wie auch gemeinsam zu optimieren.In addition, there is the possibility of both the diving spout and the To optimize the mold shape individually as well as together.
Durch das Messen der Wasserauslauftemperatur im Vergleich zur Einlauftemperatur innerhalb der einzelnen drei Zonen besteht die Möglichkeit der Optimierung der Kühlwasserregelung. In jeder Zone wird dabei die Einlauf- und Auslaufwassertemperatur sowie die Wassermenge gemessen, wobei die Wassermengen auch unabhängig voneinander regelbar sein können.By measuring the water outlet temperature in comparison to the inlet temperature within the individual three zones there is the possibility of optimizing the Cooling water control. In each zone, the inlet and Outlet water temperature and the amount of water measured, the Amounts of water can also be regulated independently of one another.
Die erfindungsgemäße Anordnung in mindestens drei Zonen und der Vergleich der spezifischen Wärmeströme in diesen Zonen zueinander erlaubt es, eine Unsymmetrie besonders zu dem im Tauchausgußbereich zu erkennen. Ein ungleichförmiger Wärmedurchgang bedingt durch Turbulenzen des Stahles in der Kokille ist ebenfalls erkennbar.The arrangement according to the invention in at least three zones and the comparison of the specific heat flows in these zones to each other allows an asymmetry especially to be recognized in the diving spout area. A non-uniform Heat transfer due to turbulence of the steel in the mold is also recognizable.
Eine mögliche Abweichung in der Kokillenmitte geht einher mit Längsrissen in der Strangoberfläche bis hin zu Durchbrüchen (Klebern). Diese Längsrisse treten besonders im mittleren Brammenbereich neben der Mittenachse im Bereich des Tauchausgusses, also im Bereich des relativ dünneren Schlackenschmierfilms auf. Dieser dünnere Schlackenschmierfilm führt zu einem erhöhten Wärmestrom und damit zu einer ungleichförmigen partiellen Strangschalenausbildung hinsichtlich der erhöhten Dicke, der verringerten Temperatur und der erhöhten Schrumpfung. Diese ungleichförmige partielle Strangschalenausbildung führt zu Längsrissen und im Extremfall zum Kleben des Stranges in der Mitte der Kokillenbreitseite und zum Durchbruch. Parallel zu diesen Störungen an der Strangschale treten entsprechend thermische partielle Belastungen der Kupferplatte auf, die zur Verringerung der Standzeit führen. Weiterhin läßt die Vorrichtung ein Wandern des Stranges in Richtung eine der Schmalseiten erkennen mit entsprechender Durchbruchgefahr infolge von Hängern, der dann durch Konizitätsregelung entgegengewirkt werden kann.A possible deviation in the middle of the mold is accompanied by longitudinal cracks in the Strand surface up to breakthroughs (adhesives). These longitudinal cracks occur especially in the middle of the slab area next to the central axis in the area of the Immersion spout, i.e. in the area of the relatively thinner slag lubrication film. This thinner slag lubrication film leads to an increased heat flow and thus to a non-uniform partial strand shell formation with regard to the increased Thickness, the reduced temperature and the increased shrinkage. This non-uniform partial strand shell formation leads to longitudinal cracks and in Extreme case for gluing the strand in the middle of the broadside of the mold and for Breakthrough. Corresponding to these disturbances on the strand shell occur accordingly thermal partial loads on the copper plate to reduce the Lead service life. Furthermore, the device allows the strand to move in Detect direction of one of the narrow sides with a corresponding risk of breakthrough as a result of hangers, which are then counteracted by conicity regulation can.
Die Abweichung des spezifischen Wärmestroms gemessen in kcal/min . m2 bzw. MW/m2 in der mittleren Zone im Vergleich zu den Randzonen gibt ein direktes Maß für das Stellglied betreffend:
- die Schmalseitenkonizität
- die Kühlwassermenge je Kühlzone
- der Hubhöhe, Frequenz und/oder Oszillationsform der Kokillenoszillation
- Tauchausgußeintauchtiefe während des Gießens.
- the narrow side taper
- the amount of cooling water per cooling zone
- the lifting height, frequency and / or form of oscillation of the mold oscillation
- Immersion pouring depth during pouring.
Die hierbei gewonnenen Erkenntnisse führen zur Optimierung:
- der Kokillenform
- der Gießschlacke und
- Tauchausgußform sowohl innen als auch außen in Verbindung mit der Kokillenform.
- the mold shape
- the pouring slag and
- Immersion mold both inside and outside in connection with the mold.
Die Erfindung erlaubt also nicht nur eine Veränderung der Gießparameter während des Gießens, insbesondere zur Durchbruchsicherung, sondern auch die Entwicklung der Kokillenform im Zusammenspiel mit der Tauchausgußform, sowohl innen wie auch außen und des Gießpulvers zu einem optimalen System "Kokille".The invention therefore not only allows a change in the casting parameters during of casting, especially to ensure breakthrough, but also development the mold shape in interaction with the immersion nozzle, both inside and out outside and the mold powder to an optimal system "mold".
