Abstract

The invention relates to a method for controlling the taper of narrow faces, adjustable between wide faces, of a liquid-cooled plate mould for the production of continuous steel slabs. In order to specify a method for controlling the taper of narrow faces, adjustable between wide faces, of a liquid-cooled plate mould for the production of continuous steel slabs, it is proposed that the temperature of the cooling fluid at the coolant outlet of each of the liquid-cooled plates of a mould should first of all be measured, that a cooling surface-related specific temperature value be formed from the measured temperature, that the specific temperature values of opposite plates be compared, furthermore that a comparison of the temperature values of each plate with the specific temperature values of the adjoining plates be carried out and that, if there is a difference between the temperature values, an actuating value corresponding to the size of the difference be applied to the drive of that narrow face which delivers the lower temperature value to bring about an increase in the taper. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Einrichtung zur Erzeugung von Stahlsträngen im Brammenformat. Beim Stranggießen von Stahl in flüssigkeitsgekühlten, aus einzelnen Platten gebildeten Kokillen zur Erzeugung von Strängen im Brammenformat wird in der Kokille aufgrund der geringen Wärmeleitfähigkeit des Stahles zunächst nur eine dünne, aus erstarrter Schmelze bestehende Strangschale gebildet. Es ist bekannt und wird vom Stranggießer angestrebt, daß die Strangschale in der Kokille möglichst mit über den Umfang gleichmäßiger Dicke entsteht, da diese dünne Strangschale außerhalb der Kokille dem ferrostatischen Druck der im Innern befindlichen Schmelze Stand halten muß. Der Fachmann weiß ferner, daß die Ausbildung der Dicke und der Gleichmäßigkeit der erstarrten Strangsschale am Austritt der Kokille von einer Reihe von Faktoren abhängig ist, wie beispielsweise Gießgeschwindigkeit, Stahltemperatur, Geometrie, Werkstoff und Konizität der Kokille und nicht zuletzt von der Art und Zusammensetzung des Schmiermittels, das auf den Gießspiegel aufgebracht wird und die Reibung zwischen Strangschale und Kokille verringern soll. The invention relates to a method and a device for Production of steel strands in slab format. When continuously casting Steel in liquid-cooled, formed from individual plates Chill molds for producing strands in slab format are placed in the mold due to the low thermal conductivity of the steel, initially only one thin strand shell formed from solidified melt. It is known and is aimed by the continuous caster that the continuous shell in the mold is made with a thickness that is uniform over the circumference, because this thin strand shell outside the mold is the ferrostatic Pressure of the melt located inside must withstand. The expert also knows that the thickness and uniformity of the solidified strand shell at the exit of the mold from a series of Factors, such as casting speed, Steel temperature, geometry, material and conicity of the mold and not least of the type and composition of the lubricant that is applied to the mold level and the friction between Strand shell and mold should reduce.

Die Tatsache, daß immer wieder Strangdurchbrüche, also Schmelzenaustritte durch die Strangschale hindurch zu verzeichnen sind, die zum Abbruch des Gießvorganges führen, zeigt, daß dieses Problem noch nicht sicher beherrscht wird, obwohl eine ganze Reihe von Vorschlägen zur Lösung dieses Problems existieren.The fact that strand breaks again and again, so Melt leaks through the strand shell can be recorded, which lead to the termination of the casting process shows that this problem still not mastered with certainty, although a whole host of proposals exist to solve this problem.

So sind aus den Schriften DE 31 10 012 C1, EP 0 114 293 B1, DE 33 09 885 A1, DE 39 08 328 A1 Vorschläge bekannt, mit denen über eine Einstellung der Konizität der Schmalseiten versucht wird, die Kühlbedingungen in der Kokille und damit die Strangsschalenbildung zu bestimmen bzw. zu beeinflussen.So are the documents DE 31 10 012 C1, EP 0 114 293 B1, DE 33 09 885 A1, DE 39 08 328 A1 proposals known with which about a setting the conicity of the narrow sides is tried, the cooling conditions in the To determine the mold and thus the strand shell formation influence.

Allen bekannten Methoden ist gemeinsam, daß die Kokille bzw. die gesamte Anlage nach Meßwerten im Vergleich zu vorgegebenen Soll-Werten gesteuert wird, wobei jedoch offen ist, inwieweit die vorgegebenen Soll-Werte den tatsächlichen Gegebenheiten oder Erfordernissen Rechnung tragen.All known methods have in common that the mold or the entire System controlled according to measured values in comparison to specified target values is, but it is open to what extent the specified target values take account of actual circumstances or requirements.

Die Erfindung löst die bestehenden Probleme bei einer flüssigkeitsgekühlten Plattenkokille zur Erzeugung von Strängen aus Stahl im Brammenformat mit zwischen Breitseitenplatten verstellbaren Schmalseitenplatten mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The invention solves the existing problems in a liquid-cooled plate mold for the production of strands Steel in slab format with adjustable between broad side plates Narrow side panels with the Features of claim 1.

Nach Durchlauf des Wassers durch die Kokille wird für jede der Schmal- und Breitseitenplatten 1, 2, 3, 4 die Temperatur des Wassers möglichst nahe an der Anschlußstelle des Wasserablaufs an der Kokillenplatte erfaßt, ebenso die jeder Seite der Platte zugeführte Wassermenge (Bezugsziffern 6 bis 13).For each of the four plates of the mold, the water inlet temperature is 5 recorded, as a rule this will be the same for all four plates, so that one measurement is sufficient. After the water has passed through the mold is for each of the narrow and broad side plates 1, 2, 3, 4 Temperature of the water as close as possible to the junction of the Water drainage detected on the mold plate, as well as that on each side of the Quantity of water supplied to plate (reference numbers 6 to 13).

Here too the narrow side, which supplies the lower temperature value, is Adjust to increase conicity.

    Werden die Werte K1 bis K6 in Zeitabständen ausgewertet oder auch kontinuierlich aufgezeichnet, so ergibt sich für einen Idealzustand, der eine gleiche Schalendicke des Stranges in der Kokille definiert, stets ein bestimmtes Verhältnis der K-Werte untereinander bzw. ein bestimmter Kurvenverlauf. Weicht ein oder mehrere Werte über ein bestimmtes Maß von den übrigen zeitgleichen Werten ab, so ist dies ein Anzeichen für eine Störung des Wärmeüberganges und damit für eine Veränderung der Strangschalenbildung in einem zuortbaren Bereich der Kokille, der gleichzeitig eine Vorwarnung für einen zu erwartenden Strangdurchbruch angibt. Diese Gefahr kann also frühzeitig durch Korrektur der Konizität der Kokille, Änderung der Gießgeschwindigkeit, der Oszillationsparameter oder der Gießpulverzusammensetzung begegnet werden.The values K1 to K6 are evaluated at intervals or also continuously recorded, the result for an ideal state is: always defines an equal shell thickness of the strand in the mold a certain ratio of the K values to each other or a certain one Curve. Deviates one or more values by a certain amount the other simultaneous values, this is an indication of one Disruption of the heat transfer and thus for a change in Strand shell formation in a locatable area of the mold, the at the same time, a warning for a strand break to be expected indicates. This risk can be avoided early by correcting the taper the mold, changing the casting speed, the oscillation parameters or the mold powder composition can be met.

Method of controlling the taper of the narrow faces - adjustable between wide faces - of a liquid-cooled plate mould for the production of strands of steel in the form of slabs; initially, and for each of the liquid-cooled plates of the mould, the temperature of the coolant liquid is measured at the coolant inlet and the coolant outlet, and the volume of coolant is measured: for a given mould format, a specific temperature value, relative to the cooling surface, is formed from the measured temperatures for each plate; to form the specific temperature value of a mould side, the heat quantity dissipated in relation to each unit of surface is recorded, the specific temperature values of opposite plates are compared, and the specific temperature values of one wide face plate are compared in each case in relation to the specific temperature values of the adjacent narrow face plate, the resulting values being recorded, at intervals or continuously, as K values; under ideal conditions there is always a specific ratio among the K values, and where any deviation by more than a certain amount occurs of one or more K values in relation to the other isochronous K values, a correction value corresponding to the amount of the difference is sent to the drive unit of that narrow face for the purpose of bringing about an increase in the taper to give the lowest specific temperature value.
    2. Method as in Claim 1,
      characterised in that
      the temperature of the coolant is measured continuously.
