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

Die Erfindung betrifft eine Vorrichtung zur Maulweitenregelung an Segmenten für Stranggießanlagen, die zumindest mit einem Positions- und Druckgeber ausgebildet sind, insbesondere an Segmenten für Brammen- und Dünnbrammen-Stranggießantagen, umfassend eine Strangführung mit einer Regelung und Segmenten für eine vorgesehene Führung eines Gußstranges unter Verwendung von Meß- und Regelsignalen. Die Erfindung betrifft auch die Verwendung der Vorrichtung.The invention relates to a device for pitch control of segments for continuous casting, which are formed at least with a position and pressure transducer, in particular to segments for slab and thin slab continuous casting, comprising a strand guide with a scheme and segments for a proposed leadership of a cast using of measuring and control signals. The invention also relates to the use of the device.

Zum Stand der Technik gehören positions- und druckgeregelte Segmente (Segmentzylinder) in Stranggießaniagen. 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. In this case, in particular for the purpose of soft reduction (SR) and liquid core reduction (LCR) method segments are made by hydraulic cylinders and assignable measuring / control and control organs in the mouth.

Üblicherweise befinden sich die hierfür erforderlichen Regelungs- und Steuerungselemente in entfernten Schalteinrichtungen der Stranggießanlagen.Usually, the control and control elements required for this purpose 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.In case of failure of the transmission organs or transmission lines, the control and / or control 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 lag 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.The document DE 100 28 304 A1 discloses a method and a device for decentralized casting data processing of the measurement data obtained on a continuous casting mold via sensors in a process computer of a continuous casting plant. This known development was based on the task of electronically processing, among other things, the casting data measured via sensors in more efficient ways, and thereby also simplifying the devices provided for this purpose. For this purpose, the measurement and control data are collected in cooled fieldbus modules directly on the continuous casting mold and transferred to bus signals in a bus line and stored at least in the control of the continuous casting and / or processed. This significantly shortens and simplifies the data path, as well as simplifying 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 Thermo-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 Kokille specific information z. B. on the thickness of the copper plates, the degree of wear, the state of the thermal sensors and / or the resistance thermosensors and the maintenance cycles are stored retrievable.

Das Dokument WO-99/46071 -A 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 werden 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 US-A discloses a pitching process for a roll segment of a continuous caster having a segment entrance side, a segment exit side, and a pair of roller supports each carrying at least two rollers extending over a support region. The roller carriers are set against each other via a positioning unit arranged on the segment input side and a positioning unit arranged on the segment output side. Each adjustment unit has two hydraulic cylinder units arranged on both sides of the support region.

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 werden, wenn der Druck in der jeweiligen Hydraulikzylindereinheit einen Grenzwert erreicht.The Anstellverfahren known therefrom is that the hydraulic cylinder units can be adjusted both position and pressure controlled that the rollers are positionally controlled via the hydraulic cylinder units to a metal strand guided by the rollers, and that the hydraulic cylinder units are switched from position- to pressure-controlled operation, if the pressure in the respective hydraulic cylinder unit reaches a limit.

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.Based on the aforementioned prior art, the present invention seeks to install a decentralized control and regulation with appropriate modules directly on a segment or directly to a hydraulic cylinder, so as to create an "intelligent segment", which also in case of failure of Communication data secures another operation.

Zur Lösung der Aufgabe wird bei einer Vorrichtung der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung vorgeschlagen, dass jedes Segment mindestens eine eigene dezentrale Regel-Systemeinheit besitzt, wie in Anspruch 1 definiert.To solve the problem, it is proposed in a device referred to in the preamble of claim 1 with the invention that each segment has at least its own decentralized control system unit, as defined in claim 1.

Neben der Ausführung der Systemeinheit mittels Regelungs- und Steuerungseinheiten auf dem Segment ist eine Ausführung mittels sogenannter intelligenter Klemmen auf dem Segment zur Reduzierung des Verkabelungsaufwandes als Altemativlösung vorgesehen.In addition to the execution of the system unit by means of control and control units on the segment, an embodiment by means of so-called intelligent terminals on the segment to reduce the cabling effort is provided as Altemativlösung.

Bei der Verwendung der Vorrichtung gemäß der Erfindung wird vorgeschlagen, dass die Meß- und Regelsignale in mindestens einer Systemeinheit unmittelbar auf dem jeweiligen Segment verarbeitet und die SOLLwert-Vorgaben von einem übergeordneten Leitsystem über einen Feldbus, z.B. Profibus, und eine Spannungsversorgung dem Segment zugeführt werden, sowie ISTwert-Daten ebenfalls über den Feldbus dem Leitsystem als Regelergebnis bzw. Prozeßzustand zurückgeführt werden.When using the device according to the invention, it is proposed that the measurement and control signals in at least one system unit be processed directly on the respective segment and that the desired value specifications are transmitted from a higher-level control system via a fieldbus, e.g. Profibus, and a power supply to the segment are supplied, and actual value data are also returned via the fieldbus the control system as a control result or process state.

Mit der Verwendung der Erfindung ist welterhin 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 use of the invention is welterhin provided that the decentralized system unit in addition to the / required task (s) for the segment employment further decentralized, segment-specific tasks such as detection and processing of other 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 regein. 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 in case of failure of the communication to the control system, the set or stored in the control module data z. For example, for the desired position or the set nominal value automatically to Reggein. The required battery unit for bridging 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.At the same time a reduction of the electrical connections between the segment and the control system is achieved with advantage, whereby a shortening of the segment change times is achieved.

Nachfolgend wird anhand von Zeichnungen gemäß Figur 1 ein Ausführungsbeispiel nach dem Stand der Technik und gemäß Figur 2 ein Ausführungsbeispiel in Form des Efindungsgegenstandes beschrieben.The following is based on drawings according to FIG. 1 an embodiment of the prior art and according to FIG. 2 an embodiment described in the form of Efindungsgegenstandes.

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.In FIG. 1 is a known per se construction of a strand guide 1, comprising a number of strand guide segments 2, which pass the strand 3, emerging from the mold, safely with increasing solidification 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 entsprechend 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 sensor 7 and preferably a pressure transducer 8. These are position- and pressure-controlled segments 2, which are adjusted by means of hydraulic cylinders and associated measuring / regulating and control devices in the jaw width as well as in the position corresponding to predetermined nominal values. The existing control and control technology is located in remote facilities or substations 4 of the continuous casting.

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 Aftemativlösung sogenannte intelligente Klemmen vorgesehen werden.The envisaged according to the invention training the strand guide in FIG. 2 In contrast to the prior art is designed so that each segment 2 has an autonomous, decentralized controller 14, which is equipped at least with a self-contained position and pressure transducer 7, 8 and preferably via a bus connection 11 or a Profibus with a higher-level control system 10th and a power supply 12 is in communication. The existing lines with connectors 13 require only a fraction of the line system 5 with connectors 6 in the prior art according to FIG. 1 , Another serious advantage arises from the fact that in case of failure of the transmission lines or connecting elements, the control or control does not collapse because of their self-sufficient position on the segments. Instead of the control and control units on the segment 2 so-called intelligent terminals can be provided as an advantageous Aftemativlösung.
