Die Erfindung betrifft ein Verfahren zur Kontrolle der Antriebskräfte von Strangführungssegmenten beim Ausfördern eines Gussstranges aus einer Stranggießanlage.The invention relates to a method for controlling the driving forces of strand guide segments when conveying a cast strand from a continuous caster.
In Stranggießanlagen, insbesondere zum Gießen von Brammen, Dünnbrammen, Vorblöcken oder Beam Blanks, werden die erzeugten Stränge von der Kokille bis mindestens zur Durcherstarrung in einem Rollenkorsett gestützt und geführt. Einzelne Rollen innerhalb dieser Strangführungsstrecke oder hinter ihr werden zur Überwindung der Ausziehwiderstände, welchen der Strang auf seinem Weg durch die Rollenführung unterworfen ist, angetrieben. Die Leistung dieser Antriebe wird im Allgemeinen so bemessen, dass einerseits bei jeder denkbaren Betriebssituation ein sicheres Ausfördem des Stranges gewährleistet ist, andererseits aber die Herstellkosten möglichst niedrig gehalten und die Antriebe nicht unnötig überdimensioniert werden.In continuous casting plants, in particular for casting slabs, thin slabs, Preblocks or beam blanks, the strands produced are from the mold to supported and guided at least for solidification in a roller corset.

The performance of these drives will generally dimensioned so that, on the one hand, in every conceivable operating situation a safe discharge of the strand is guaranteed, but on the other hand the Manufacturing costs are kept as low as possible and the drives are not unnecessarily oversized become.

Knowing the upcoming pull-out force, usually to overcome the pull-out resistance is required can be used for the evaluation of the operational Processes of a continuous caster are used.
Aus der DE 29 23 900 C2 ist ein Verfahren zum Verhindern von Durchbrüchen des Stranges in Stranggießanlagen bekannt, wobei Änderungen des Stranges und der Betriebsgrößen der Stranggießanlage gemessen und mit einem Grenzwert verglichen werden, worauf bei Überschreitung ein Signal für eine Gegenmaßnahme erzeugt wird. Unterhalb der Kokille werden am ersten Segment der Strangführung die durch mechanische Widerstände verursachten Kraftänderungen der Ausziehkräfte gemessen und für eine Veränderung des Gießprozesses oder dessen Beendigung herangezogen. Die Kraftänderungen werden mittels Druckmessdosen oder Dehnungsmessstreifen gemessen.DE 29 23 900 C2 describes a method for preventing breakthroughs of the strand in continuous casting plants known, changes in the strand and the operating parameters of the continuous caster and measured with a limit value be compared, whereupon a signal for a countermeasure is exceeded is produced.

Das Verfahren betrifft die Kontrolle der Antriebskräfte des ersten Strangführungssegments.Document EP-A-1 193 007 describes a method and a device to determine the position of the final solidification in the casting strand during continuous casting of metals, especially steel, in which the one produced in the continuous casting mold Casting strand guided in support segments, cooled and through the support segments is pulled out with driven support roller pairs. The procedure concerns the control of the driving forces of the first strand guide segment.

Es schlägt vor, durch Berechnung oder Messung der Drehmomente der Motoren, die mit den jeweiligen Antriebsrollen verbundlen sind, die Antriebsmomente der Antriebsrollen zu berechnen. Die Ziehkraft am Strang durch Antriebsrollen wird aus den erhaltenen Drehmomenten berechnet.JP 03 254 343 A describes a method for measuring bulges of the strand during continuous casting. It suggests by calculation or measuring the torques of the motors with the respective drive rollers are connected to calculate the drive torques of the drive rollers.

Der vorliegenden Erfindung liegt nunmehr die Aufgabe zugrunde, Änderungen der Antriebskräfte von Strangantrieben frühzeitig zu erkennen und zu analysieren, dabei ihre Ursachen zu ermitteln und Maßnahmen für einen vorausschauenden, rechtzeitigen Schutz der Anlage vor übermäßigem Verschleiß mit der Folge eines längeren Ausfalls zu veranlassen, wofür insbesondere der in Gießrichtung auftretende mechanische Widerstand der Segmente gegen die Antriebskräfte genutzt werden soll.The present invention is based on the object of changes to the To identify and analyze the driving forces of strand drives at an early stage determine their causes and take measures for a forward-looking, timely protection of the system against excessive wear resulting in a prolonged failure, for which in particular that occurring in the casting direction mechanical resistance of the segments against the driving forces shall be.
Die Erfindung geht dabei von einem Verfahren zur Kontrolle der Antriebskräfte von Strangführungssegmenten beim Ausfördern eines Gussstranges aus einer Stranggießanlage aus, wobei eine höchstzulässige Antriebskraft zum Ausfördem des Stranges vorgegeben wird und die Einzel-Antriebskräfte einer Anzahl von Segmenten gemessen, daraus die Summe der einzelnen Kräfte errechnet wird, diese mit der höchstzulässigen Antriebskraft verglichen und bei deren Überschreitung die Anlage zurückgefahren oder abgeschaltet wird. Dabei wird unter der höchstzulässigen Antriebskraft der maximal zulässige Strangwiderstand und unter der Einzel-Antriebskraft der Einzelwiderstand verstanden. Hierzu wird mit der Erfindung vorgeschlagen, daß mittels Inklinometer an den Unterbaukonstruktionen der Auflagepunkte der Strangführungssegmente zunächst die Normalneigung ohne Strang gemessen wird und nachfolgend weitere Neigungsmessungen während des Gießbetriebes durchgeführt werden, wobei die Differenzen der Neigungswerte über konstruktionsbedingte Umrechnungsfaktoren bedingt durch Verformung der konstruktiven Trageeinrichtung durch Krafteinwirkung, die anstehenden Ausziehkräfte, also die Einzelwiderstände und somit die Einzel-Antriebskräfte angeben.The invention is based on a method for controlling the driving forces Strand guide segments when conveying a cast strand out of one Continuous casting machine, with a maximum permissible driving force for conveying of the strand is specified and the individual driving forces of a number of Measured segments, from which the sum of the individual forces is calculated, this is compared with the maximum permissible driving force and when it is exceeded the system is shut down or switched off. It is under the maximum permissible driving force, the maximum permissible strand resistance and the individual driving force means the individual resistance. To do this, use the invention proposed that by inclinometer on the substructures the support points of the strand guide segments initially the normal slope is measured without a strand and then further inclination measurements be carried out during the casting operation, the differences in the inclination values about construction-related conversion factors caused by Deformation of the structural support device due to the action of force Extraction forces, i.e. the individual resistances and thus the individual drive forces specify.
Durch die Anpassung der Betriebsdaten an die höchstzulässigen Antriebskräfte wird zugleich ein optimaler Betriebszustand eingeregelt, der ein maximales Ausbringen des Gussproduktes ohne schädliche Überlastung der Stranggießanlage ermöglicht.By adapting the operating data to the maximum permissible driving forces At the same time, an optimal operating state is set, which ensures maximum output of the cast product without damaging the continuous caster allows.
Zu diesem Zweck ist erfindungsgemäß vorgesehen, dass für ein einzelnes Segment die hochstzulässige Antriebskraft vorgegeben und mit der aktuellen Antriebskraft so lange verglichen wird, bis die höchstzulässige Antriebskraft (Widerstand) erreicht ist. Darüber hinaus gehende Steigerungen der Antriebskraft werden systemtechnisch verhindert.For this purpose, the invention provides that for a single segment the maximum permissible driving force is specified and with the current driving force until the maximum permissible driving force (resistance) is reached. Beyond that there will be increases in driving force systemically prevented.
Dabei kann mit Vorteil auch so vorgegangen werden, dass für ein einzelnes Segment die höchstzulässige Antriebskraft vorgegeben, mit der aktuellen Antriebskraft verglichen und bei deren Überschreitung diese so weit zurückgeführt wird, bis sie zumindest übereinstimmen.It can also be advantageously used for a single segment the maximum permissible driving force is specified with the current driving force compared and if they are exceeded this is reduced until it at least match.
