Description

Die Erfindung betrifft eine Steuer- und / oder Regeleinrichtung für ein Stützrollengerüst einer Stranggießvorrichtung für Metalle, insbesondere für Stahlwerkstoffe, das aus mehreren aufeinander folgenden Rollensegmenten besteht, die jeweils über die Stützrollen tragenden Unterrahmen und einen gegenüberliegenden Oberrahmen mittels paarweisen Kolben-Zylinder-Einheiten gegeneinander geregelt anstellbar sind, zum Fördern, Richten und / oder zur Verbesserung der Innenqualität und zur Dickenänderung, wobei die Messdaten von Feldgeräten dezentral erfasst und verarbeitet werden.The invention relates to a control and / or regulating device for a support roller stand of a continuous casting apparatus for metals, in particular steel materials, which consists of several successive roller segments, each controlled via the support rollers supporting subframe and an opposite upper frame by means of paired piston-cylinder units against each other can be adjusted, for conveying, straightening and / or improving the internal quality and the thickness change, the measurement data of field devices are detected and processed decentralized.

Zur Anstellung nur eines Hydraulikzylinders sind die verschiedenen Signale, die im Bereich dieses Hydraulikzylinders entstehen und umgesetzt werden müssen, mit einem Regelungsteil elektrisch zu verbinden. Aus diesem Grund ist einerseits die Feldverkabelung der Rollensegmente und damit der gesamten Strangführung bis zur zentral installierten Regelungsschaltung sehr aufwendig. Andererseits ist aufgrund der großen Anzahl der zu verarbeitenden Signale eine zentrale Regelungsschaltung ebenfalls sehr aufwendig.For the employment of only one hydraulic cylinder, the various signals that arise and must be implemented in the region of this hydraulic cylinder to be electrically connected to a control part. For this reason, on the one hand, the field wiring of the roller segments and thus the entire strand management to the centrally installed control circuit is very expensive. On the other hand, due to the large number of signals to be processed, a central control circuit is also very expensive.

Die Distanz zur Regelungsschaltung im Steuerhaus auf der Gießbühne ist nach wie vor sehr groß und kann bis zu 100 m betragen. Da jedes Rollensegment 4 Positionsgeber, 4 Sätze Regelungsventile (Servo- bzw. Schaltventile) und in einigen Fällen acht Druckaufnehmer / Druckgeber aufweist, müssen je Segment vier synchron-serielle Schnittstellen und 12 Analog- bzw. Digital-Signale verarbeitet werden. In einer Stranggießanlage befinden sich oft mehr als 15 angestellte Rollensegmente: in diesen sind 60 synchron-serielle Schnittstellen und 180 Analog- bzw. 240 Digital-Signale von einem Regelventil zu verarbeiten. Bei dieser hohen Anzahl von zu verarbeitenden Signalen sind die Kosten für eine zentrale Regelungsschaltung zu hoch und die zentrale Regelungsschaltung stößt an ihre Grenzen der Leistungsfähigkeit.The distance to the control circuit in the wheelhouse on the casting platform is still very large and can be up to 100 m. Since each roller segment has 4 position sensors, 4 sets of control valves (servo and switching valves) and in some cases eight pressure transducers / pressure transducers, four synchronous-serial interfaces and 12 analogue or digital signals must be processed per segment. In a continuous caster there are often more than 15 staffed roller segments: in these 60 synchronous serial interfaces and 180 analog or 240 digital signals are to be processed by a control valve. With this large number of signals to be processed, the cost of a central control circuit is too high and the central control circuit reaches its limits of performance.

Es ist eine dezentrale Regelungsschaltung bekannt ( WO 01 / 94052 A1 ), die ein Verfahren zur dezentralen Gießdatenverarbeitung der an einer Stranggießkokille über Sensoren gewonnenen Messdaten in einem Prozessrechner der Steuerung der Stranggießanlage die Messstrecke effizienter macht und vereinfacht die Einrichtung, indem 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 werden.There is a decentralized control circuit known ( WO 01/94052 A1 ), which makes a method for decentralized Gießdatenverarbeitung the measurement data obtained on a continuous casting mold sensors in a process control of the continuous casting the route more efficient and simplifies the device by the measurement and control data collected in cooled fieldbus modules directly on the continuous casting mold and Bus signals are transferred to a bus line and stored at least in the control of the continuous casting and / or processed.

Die europäische Patentanmeldung EP 1475 169 A1 offenbart eine Steuer- oder Regeleinrichtung für ein Stützrollengerüst einer Stranggießvorrichtung für Metalle, insbesondere für Stahlwerkstoffe. Das Stützrollengerüst besteht aus mehreren in Strangführungsrichtung aufeinander folgenden Rollensegmenten, die jeweils über einen Stützrollen tragenden Unterrahmen und einen Stützrollen tragenden Oberrahmen verfügen. Der Unterrahmen und der gegenüberliegende Oberrahmen sind mittels paarweisen Kolben-Zylinder-Einheiten gegeneinander geregelt anstellbar zum Fördern, Richten und / oder zum Verbessern der Innenqualität und zum Ändern der Dicken der Metalle. Auf dem Oberrahmen des Rollensegments sind die Signale von Positionsgebern der Hydraulik-Zylinder-Einheiten jeweils an einen Klemmenkasten geführt und von dem Klemmenkasten ist ein Kabelpaket über eine lösbare Medienkupplung auf ein ortsfestes Hallengerüst geführt.The European patent application EP 1475 169 A1 discloses a control or regulating device for a support roll stand of a continuous casting apparatus for metals, in particular for steel materials. The support roll stand consists of several successive in strand guide direction roller segments, each having a support rollers supporting sub-frame and a support rollers supporting upper frame. The subframe and the opposite upper frame are adjusted by means of paired piston-cylinder units against each other regulated for conveying, straightening and / or improving the internal quality and changing the thicknesses of the metals. On the upper frame of the roller segment, the signals from position sensors of the hydraulic cylinder units are each guided to a terminal box and of the terminal box a cable package is guided via a detachable media coupling on a stationary hall scaffold.

Ausgehend von der EP 1475 169 A1 als nächstliegendem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Feldverkabelung und das Regelungskonzept für ein Stützrollengerüst einer Stranggießvorrichtung zu verbessern.Starting from the EP 1475 169 A1 As the closest prior art, the invention has the object to improve the field wiring and the control concept for a support roll stand a continuous casting.

Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst, indem für jedes Rollensegment ein separater Achsen-Regler mit einem angeschlossenen Ventilstand auf dem ortsfesten Hallengerüst angeordnet ist und indem Signale von sämtlichen Achsen-Reglern jeweils über ein Feldbusmodul zu einer gemeinsamen speicherprogrammierbaren Steuerung in einen Steuerraum der Stranggießvorrichtung geführt sind.This object is solved by the subject matter of patent claim 1 by a separate axis controller is arranged with a connected valve stand on the stationary hall frame for each roller segment and in that signals from all the axis controllers are each guided via a fieldbus module to a common programmable logic controller in a control space of the continuous casting apparatus.

Dadurch wird die Steuerung und die Regelung verbessert bzw. vereinfacht.This improves or simplifies the control and regulation.

Der Achsen-Regler arbeitet für jedes Rollensegment separat und übernimmt sämtliche Regelungs- und Überwachungsaufgaben. Sämtliche Achsen-Regler kommunizieren mit der speicherprogrammierten Steuerung über ein Feldbusmodul. Solche Achsen-Regler sind auf speziellen Mikroprozessoren basierende Schaltungen, die zur Steuerung von Servo-Achsen eingesetzt werden. Die Standard-Software in der Bewegungs-Steuerung fügt eine Echtzeit-Steuerung für die Achsen-Einstellung ein. Die Bewegungs-Steuerung besitzt bspw. Schnittstellen für:

  • Absolut- oder Inkremental-Positionsgeber
  • Digital- oder Analog- Ein- oder Ausgänge,
  • einen Feldbus,
  • ein Netzwerk.
Die für die Anwendung eingesetzte Bewegungs-Steuerung umfasst eine Tastatur und eine Datenanzeigeeinrichtung ( Display). Die Anwendungs-Software ist Standard und ist in einem wiederholbaren Speicher gespeichert. Die Bewegungs-Steuerung ist in der Lage, mehrere Achsen zu steuern. Auf einem grafischen Menu basierend, wird die Bewegungs-Steuerung über Parameter an den Achsen-Typ angepasst und an den Typ der Positions-Rückführung. Ein Programmieren ist nicht notwendig. Über den Feldbus- oder den Netzwerks-Anschluss erhält die Bewegungs-Steuerung die erforderlichen Sollwerte und die Start-Bewegung und koppelt diese auf das übergeordnete System mit der Position und einer Zustandsanzeige zurück. Die Anwendung erfolgt auf die Kolben-Zylinder-Einheiten der Rollensegmente, d.h. deren Hauptachsen, wie bspw. der Hydraulikzylinder-Achse:The axis controller works separately for each roller segment and handles all control and monitoring tasks. All axis controllers communicate with the programmable controller via a fieldbus module. Such axis controllers are special microprocessor-based circuits used to control servo axes. The standard motion control software adds a real-time control for axis adjustment. The motion control has, for example, interfaces for:
  • Absolute or incremental position encoder
  • Digital or analog inputs or outputs,
  • a fieldbus,
  • a network.
The motion control used for the application includes a keyboard and a data display. The application software is standard and stored in a repeatable memory. The motion control is able to control multiple axes. Based on a graphical menu, the motion control is adjusted via parameters to the axis type and to the type of position feedback. Programming is not necessary. The motion control receives the required setpoints and the start movement via the fieldbus or network connection and links these back to the higher-level system with the position and a status display. The application is made to the piston-cylinder units of the roller segments, ie their main axes, such as. The hydraulic cylinder axis:

Eine Ausgestaltung sieht vor, dass der Achsen-Regler die gespeicherten Signale zum Positionieren der Stützrollen, Synchronisieren der angetriebenen Stützrollen von Nachbar-Rollensegmenten, für linke oder rechte Hydraulikzylinder bzw. für die Einlaufseite oder Auslaufseite, die Überwachung des Zustandes der Sensoren, eine Rollensegment-Kodierung, für Wartungszyklen u. dgl. verarbeitet.One embodiment provides that the axis controller stores the stored signals for positioning the support rollers, synchronizing the driven support rollers of adjacent roller segments, for left or right hydraulic cylinders or for the inlet side or outlet side, monitoring the state of the sensors, a Rollensegment- Coding, for maintenance cycles u. Like. Processed.

Eine andere Ausgestaltung besteht darin, dass die Klemmenkästen mittels des auf dem Oberrahmen des Rollensegmentes vorhandenen Maschinenkühlwassers gekühlt sind.Another embodiment is that the terminal boxes are cooled by means of existing on the upper frame of the roller segment machine cooling water.

Weitere Erfindungsmerkmale ergeben sich dadurch, dass die Feldbusmodule physikalisch mittels elektrischen Metallleitungen, Lichtwellenleitern oder drahtloser Übertragungstechnik oder Infrarot-Signalen anschließbar sind.Further features of the invention result from the fact that the fieldbus modules can be physically connected by means of electrical metal lines, optical waveguides or wireless transmission technology or infrared signals.

Weitere Merkmale sind, dass die Kabel des Kabelpakets für die Spannungsversorgung, die Achsen-Regler und die Feldbusmodule mittels einer gemeinsamen Steckverbindung angeschlossen sind.Further features are that the cables of the cable package for the power supply, the axis controller and the field bus modules are connected by means of a common plug connection.

Schließlich ist eine Ausgestaltung dadurch gegeben, dass die Kabel für die Signale der Positionsgeber, vom Klemmenkasten auf dem Rollensegment mittels einer Medienkupplung als lösbare Steckverbindung zum Achsen-Regler ausgebildet ist. Hier müssen lediglich die in den Hydraulikzylindern integrierten Positionsgeber eines jeden Rollensegmentes über die Steckverbindung zum Ventilstand aus dem Hallen-Gerüst und von dort aus mit allen anderen Signalen mit dem vor Ort installierten Achsen-Regler verbunden werden.Finally, an embodiment is given by the fact that the cable for the signals of the position sensor, is formed by the terminal box on the roller segment by means of a media coupling as a detachable plug connection to the axis controller. Here only the integrated in the hydraulic cylinders position sensor of each roller segment must be connected via the connector to the valve from the hall scaffold and from there with all other signals with the installed on-site axis controller.
