Abstract

The invention relates to a method for adjusting the feed opening of segments for continuous casting systems, especially position-controlled segments for slab and thin-slab continuous casting systems which comprise a strand guide (1) with segments (2) for a predetermined guidance of a cast strand using measuring and control signals. In order to provide an independent intelligent segment, the measuring and control signals are processed in at least one system unit (14') directly on the respective segment (2) and the set values are fed to the segment (2') by a superordinate control system (10) via a field bus (11), for example a profibus and a power supply (12'). Actual values are returned to the control system (10') via the field bus (11) as the result of control or as a process status. The system units (14) present on the segment (21) are supplied with segment-specific data such as rigidity coefficients, roller diameter, control parameters, feed opening basic settings and adjustment quota. The invention also relates to a device for carrying out the method.

Description

Maulweitenregelung an Segmenten für StranggießanlagenWidth of mouth regulation on segments for continuous casting plants
Die Erfindung betrifft ein Verfahren zur Maulweitenregelung an Segmenten für Stranggießanlagen, insbesondere an positionsgeregelten Segmenten für Brammen- und Dünnbrammen-Stranggießanlagen, umfassend eine Strangführung mit Segmenten für eine vorgesehene Führung eines Gußstranges unter Verwendung von Meß- und Regelsignalen. Die Erfindung betrifft auch eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for regulating the width of the mouth on segments for continuous casting plants, in particular on position-controlled segments for slab and thin slab continuous casting plants, comprising a strand guide with segments for the intended guidance of a cast strand using measurement and control signals. The invention also relates to an apparatus for performing the method.
Zum Stand der Technik gehören positions- und druckgeregelte Segmente (Segmentzylinder) in Stranggießanlagen. Hierbei werden insbesondere zum Zwecke von Softreduction- (SR) und Liquid-Core-Reduction (LCR)- Verfahren Segmente über Hydraulikzylinder und zuordenbare Meß-/Regel- und Steuerungsorgane in der Maulweite angestellt.The state of the art includes position and pressure-controlled segments (segment cylinders) in continuous casting plants. Here, in particular for the purpose of soft reduction (SR) and liquid core reduction (LCR) processes, segments are set up in the jaw width via hydraulic cylinders and assignable measuring / regulating and control elements.
Üblicherweise befinden sich die hierfür erforderlichen Regelungs- und Steue- rungselemente in entfernten Schalteinrichtungen der Stranggießanlagen.Usually, the control and control elements required for this are located in remote switching devices of the continuous casting plants.
Bei einem Ausfall der Übertragungsorgane bzw. Übertragungsleitungen bricht die Regelung und/oder Steuerung zusammen.If the transmission elements or transmission lines fail, the regulation and / or control system breaks down.
Das Dokument DE 100 28 304 A1 offenbart ein Verfahren und eine Einrichtung zur dezentralen Gießdatenverarbeitung der an einer Stranggießkokille über Sensoren gewonnenen Meßdaten in einem Prozeßrechner einer Stranggießanlage. Dieser bekannten Entwicklung liegt die Aufgabe zugrunde, auf elektronischem Weg u. a. die über Sensoren gemessenen Gießdaten auf effizienteren Wegen zu verarbeiten, und dadurch auch die hierfür vorgesehenen Einrichtungen zu vereinfachen. Hierzu werden die Meß- und Steuerdaten in gekühlten Feldbus-Modulen unmittelbar auf der Stranggießkokille gesammelt und in Bus- Signale in eine Bus-Leitung überführt und zumindest in der Steuerung der Stranggießanlage gespeichert und/oder verarbeitet. Dadurch wird der Datenweg erheblich verkürzt und vereinfacht, und auch die Einrichtung vereinfacht.Document DE 100 28 304 A1 discloses a method and a device for decentralized casting data processing of the measurement data obtained on sensors in a continuous casting mold in a process computer of a continuous casting plant. This known development is based on the task of electronically processing, among other things, the casting data measured by sensors in a more efficient way, and thereby also simplifying the devices provided for this purpose. For this purpose, the measurement and control data are cooled Fieldbus modules are collected directly on the continuous casting mold and converted into bus signals in a bus line and at least stored and / or processed in the control of the continuous casting system. This significantly shortens and simplifies the data path and also simplifies the setup.
Ein weiterer Vorteil dieser Entwicklung ergibt sich dadurch, dass in den Feldbus-Modulen auf der Stranggießkokille kokillenspezifische Informationen z. B. über die Dicke der Kupferplatten, den Abnutzungsgrad, den Zustand der Ther- mo-Sensoren und/oder der Widerstands-Thermosensoren und die Wartungszyklen abrufbar gespeichert sind.Another advantage of this development results from the fact that in the fieldbus modules on the continuous casting mold, mold-specific information, e.g. B. on the thickness of the copper plates, the degree of wear, the state of the thermal sensors and / or the resistance thermal sensors and the maintenance cycles are stored.
Das Dokument WO 99/46071 offenbart ein Anstellverfahren für ein Rollensegment einer Stranggießanlage, das eine Segmenteingangsseite, eine Segmentausgangsseite und ein Paar Rollenträger aufweist, die je mindestens zwei sich über einen Stützbereich erstreckende Rollen tragen. Die Rollenträger wer- den über eine an der Segmenteingangsseite und eine an der Segmentausgangsseite angeordnete Anstelleinheit gegeneinander angestellt. Jede Anstelleinheit weist zwei beidseits des Stützbereiches angeordnete Hydraulikzylindereinheiten auf.The document WO 99/46071 discloses an adjustment method for a roller segment of a continuous caster, which has a segment entrance side, a segment exit side and a pair of roller carriers, each of which carries at least two rollers extending over a support area. The roller carriers are set against each other via a positioning unit arranged on the segment entrance side and on the segment exit side. Each adjusting unit has two hydraulic cylinder units arranged on both sides of the support area.
Das hieraus bekannte Anstellverfahren besteht darin, dass die Hydraulikzylindereinheiten sowohl positions- als auch druckgeregelt anstellbar sind, dass über die Hydraulikzylindereinheiten die Rollen positionsgeregelt an einen von den Rollen geführten Metallstrang angestellt werden, und dass die Hydraulikzylindereinheiten vom positions- auf druckgeregelten Betrieb umgeschaltet wer- den, wenn der Druck in der jeweiligen Hydraulikzylindereinheit einen Grenzwert erreicht.The adjustment method known from this consists in that the hydraulic cylinder units can be adjusted both in a position-controlled and pressure-controlled manner, that the rollers are adjusted in a position-controlled manner on a metal strand guided by the rollers, and that the hydraulic cylinder units are switched over from position-controlled to pressure-controlled operation when the pressure in the respective hydraulic cylinder unit reaches a limit value.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine dezentrale Steuerung und Regelung mit entsprechenden Modulen unmittelbar auf einem Segment bzw. direkt an einem Hydraulikzylinder zu installieren, um damit ein "intelligentes Segment" zu schaffen, welches auch bei einem Ausfall von Kommunikationsdaten einen weiteren Betrieb sichert.On the basis of the aforementioned prior art, the object of the invention is a decentralized control and regulation with corresponding modules directly on a segment or directly on a hydraulic cylinder to be installed in order to create an "intelligent segment" which ensures further operation even in the event of communication data failure.
Zur Lösung der Aufgabe wird mit einem Verfahren nach der Erfindung vorgeschlagen, dass Meß- und Regelsignale in wenigstens einer Systemeinheit un- mittelbar auf dem jeweiligen Segment verarbeitet und die SOLLwert-Vorgaben von einem übergeordneten Leitsystem über einen Feldbus, z. B. Profibus, dem Segment zugeführt werden sowie (STwert-Daten ebenfalls über den Feldbus dem Leitsystem als Regelergebnis bzw. als Prozeßzustand zurückgeführt werden. In Fortbildung der Erfindung werden den auf dem Segment befindlichen Systemeinheiten segmentspezifisiche Informationen wie Steifigkeitskoeffezien- ten, Rollendurchmesser, Reglerparameter, Maulweitengrundeinstellungen und Anstellquoten zugeführt.To achieve the object, it is proposed with a method according to the invention that measurement and control signals are processed in at least one system unit directly on the respective segment and the setpoint values are transmitted by a higher-level control system via a fieldbus, eg. B. Profibus, are fed to the segment and (STvalue data are also returned to the control system as a control result or as a process state via the fieldbus. In a further development of the invention, the system units located on the segment are segment-specific information such as stiffness coefficients, roller diameter, controller parameters, Basic width settings and employment rates supplied.
Mit der Erfindung ist weiterhin vorgesehen, dass der dezentralen Systemeinheit neben der/den erforderlichen Aufgabe (n) für die Segmentanstellung weitere dezentrale segmentspezifische Aufgabenstellungen wie Erfassung und Verarbeitung weiterer Meßdaten, z. B. Lagerkraftüberwachung, Temperaturmessungen und -regelungen, Kalibrierdaten zugeordnet werden.With the invention it is further provided that the decentralized system unit in addition to the task (s) required for segment operation further decentralized segment-specific tasks such as acquisition and processing of further measurement data, eg. B. Bearing force monitoring, temperature measurements and controls, calibration data can be assigned.
Mit den erfindungsgemäßen Maßnahmen wird das Segment in die Lage versetzt, auch bei Ausfall der Kommunikation zum Leitsystem, die eingestellten oder im Regelmodul abgelegten Daten z. B. für die SOLLposition bzw. den eingestellten SOLLkraftwert selbstständig zu regeln. Die hierzu erforderliche Batterieeinheit zur Überbrückung des Kommunikationsausfalls befindet sich ebenfalls auf dem Segment.With the measures according to the invention, the segment is enabled, even if the communication to the control system fails, the data set or stored in the control module, for. B. for the TARGET position or the set TARGET force value independently. The battery unit required to bridge the communication failure is also located on the segment.
Zugleich wird mit Vorteil eine Reduzierung der elektrischen Steckverbindungen zwischen dem Segment und dem Leitsystem erreicht, wodurch eine Verkürzung der Segmentwechselzeiten erreicht wird. Eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens sieht vor, dass jedes Segment mindestens eine dezentrale Systemeinheit besitzt, die zumindest mit einem Positions- und Druckgeber ausgebildet ist und vorzugsweise über einen Feldbus bzw. Profibus mit einem übergeordneten Leitsystem und einer Spannungsversorgung in Verbindung steht.At the same time, the electrical plug connections between the segment and the control system are advantageously reduced, thereby shortening the segment changeover times. A device for carrying out the method according to the invention provides that each segment has at least one decentralized system unit which is designed with at least one position and pressure sensor and is preferably connected to a higher-level control system and a voltage supply via a fieldbus or Profibus.
Neben der Ausführung der Systemeinheit mittels Regelungs- und Steuerungseinheiten auf dem Segment ist eine Ausführung mittels sogenannter intelligenter Klemmen auf dem Segment zur Reduzierung der Verkabelungsaufwandes als Alternativlösung vorgesehen.In addition to the execution of the system unit by means of regulating and control units on the segment, an execution by means of so-called intelligent terminals on the segment to reduce the cabling effort is provided as an alternative solution.
Nachfolgend wird anhand von Zeichnungen gemäß Figur 1 ein Ausführungsbeispiel nach dem Stand der Technik und gemäß Figur 2 ein Ausführungsbeispiel in Form des Erfindungsgegenstandes beschrieben.An exemplary embodiment according to the prior art and an exemplary embodiment according to FIG. 2 in the form of the subject matter of the invention are described below with reference to drawings in accordance with FIG.
In Figur 1 ist eine an sich bekannte Bauweise einer Strangführung 1 dargestellt, umfassend eine Anzahl von Strangführungssegmenten 2, welche den Strang 3, aus der Kokille austretend, mit zunehmender Erstarrung durch die Bereiche von Softreduction bzw. Liquid-Core-Reduction sicher hindurchführen.1 shows a construction of a strand guide 1 known per se, comprising a number of strand guide segments 2, which, with increasing solidification, guide the strand 3, emerging from the mold, safely through the areas of soft reduction or liquid core reduction.
Die Segmente 2 (vergrößert dargestellt) sind mit Hydraulik-Stellvorrichtungen versehen, die ihrerseits mit einem Positionsgeber 7 und vorzugsweise einem Druckgeber 8 ausgestattet sind. Es handelt sich dabei um positions- und druckgeregelte Segmente 2, die über Hydraulikzylinder und zugeordnete Mess- /Regel- und Steuerungsorgane in der Maulweite sowie in der Position entspre- chend vorgegebener SOLLWerte angestellt werden. Die hierfür vorhandene Regelungs- und Steuerungstechnik befindet sich in entfernten Einrichtungen bzw. Schaltstationen 4 der Stranggießanlage.The segments 2 (shown enlarged) are provided with hydraulic adjusting devices, which in turn are equipped with a position transmitter 7 and preferably a pressure transmitter 8. These are position- and pressure-controlled segments 2, which are adjusted by means of hydraulic cylinders and assigned measuring / regulating and control elements in the jaw width and in the position according to predefined target values. The existing regulation and control technology is located in remote facilities or switching stations 4 of the continuous casting plant.
Die gemäß der Erfindung vorgesehene Ausbildung der Strangführung in Figur 2 ist im Gegensatz zum Stand der Technik so ausgebildet, dass jedes Segment 2 einen autonomen, dezentralen Regler 14 besitzt, der zumindest mit einem selbstständigen Positions- und Druckgeber 7, 8 ausgestattet und vorzugsweise über eine Busverbindung 11 bzw. einen Profibus mit einem übergeordneten Leitsystem 10 und einer Spannungsversorgung 12 in Verbindung steht. Die hierfür vorhandenen Leitungen mit Steckverbindungen 13 erfordern nur einen Bruchteil des Leitungssystems 5 mit Steckverbindungen 6 beim Stand der Technik gemäß Figur 1. Ein weiterer gravierender Vorteil ergibt sich daraus, dass bei einem Ausfall der Übertragungsleitungen bzw. Verbindungselemente die Regelung oder Steuerung wegen ihrer autarken Position auf den Segmenten nicht zusammenbricht. Statt der Regelungs- und Steuerungseinheiten auf dem Segment 2 können als vorteilhafte Alternativlösung sogenannte intelligente Klemmen vorgesehen werden. In contrast to the prior art, the formation of the strand guide in FIG. 2 provided in accordance with the invention is such that each segment 2 has an autonomous, decentralized controller 14, which has at least one independent position and pressure transmitter 7, 8 and is preferably connected via a bus connection 11 or a Profibus to a higher-level control system 10 and a voltage supply 12. The existing lines with plug connections 13 require only a fraction of the line system 5 with plug connections 6 in the state of the art according to FIG does not collapse on the segments. Instead of the regulation and control units on segment 2, so-called intelligent terminals can be provided as an advantageous alternative solution.
