Die Erfindung betrifft eine Stranggießmaschine mit einer Stranggießkokille für das Gießen von flüssigen Metallen, insbesondere von Stahlwerkstoffen, mit die Gießform bildenden Breitseitenplatten, zwischen denen beidseitig zur Bildung der Gießstrangbreite unter Berücksichtigung der Schrumpfung des Gießstrangs einstellbare Schmalseitenplatten angeordnet sind, an denen jeweils zwei vertikal beabstandete Kolben-Zylinder-Einheiten als Stellglieder und Stützlager vorgesehen sind, deren Stellung über Feldmessgeräte gemessen, die Messdaten über Feldbus-Module als BUS-Signale in eine BUS-Leitung überführt und in einer Steuerung der Stranggießmaschine gespeichert und nach Verarbeitung als Steuersignale zu den Stellgliedern rückführbar sind.The invention relates to a continuous casting machine with a continuous casting mold for the casting of liquid metals, in particular steel materials, with the casting forming wide side plates between which are arranged on both sides to form the Gießstrangbreite taking into account the shrinkage of the casting strand adjustable narrow side plates, in each case two vertically spaced pistons Cylinder units are provided as actuators and support bearings whose position measured by field measuring devices, transferred the measurement data via fieldbus modules as BUS signals in a BUS line and stored in a control of the continuous casting machine and traceable after processing as control signals to the actuators ,
Eine derartige Stranggießmaschine ist aus der WO 01 / 94052 A1 bekannt. Dort ist eine Stranggießmaschine zur dezentralen Gießdatenverarbeitung der an einer Stranggießkokille über Sensoren gewonnenen Messdaten in einem Prozessrechner der Steuerung der Stranggießanlage beschrieben. Die dezentrale Aufnahme der Messdaten macht die Messstrecke effizienter und vereinfacht die Messeinrichtungen, 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.Such a continuous casting machine is known from WO 01/94052 A1. There, a continuous casting machine for decentralized casting data processing of the measuring data obtained by sensors on a continuous casting mold is described in a process computer of the control of the continuous casting plant. The decentralized recording of the measured data makes the measuring section more efficient and simplifies the measuring equipment by the measurement and control data collected in cooled fieldbus modules directly on the continuous casting mold and transferred in BUS signals in a BUS line and stored at least in the control of the continuous casting and / or processed.
Für die Verstellung einer an der Schmalseitenplatte angelenkten Kolbenstange bzw. eines Hydraulikzylinders sind verschiedene Signale, die in der Nähe des Hydraulikzylinders entstehen bzw. umgesetzt werden müssen, mit einer Regelungsschaltung elektrisch zu verbinden. Der für die Anstellung der hydrauli- sehen Komponenten notwendige Ventilstand ist im allgemeinen an dem Hallen- Gerüst im Bereich der Gießbühne oder unterhalb derselben (auf dem sog. Festland) angeordnet. Die Steuerung ist normalerweise im Bereich der Gießbühne im Steuerraum installiert. Von Bedeutung ist für die Feldgeräte im Bereich der Stranggießkokille, dass eine Trennung vorhanden ist, weil die Stranggießkokille schnell aus- und wieder eingebaut werden muss. Die Messdaten können daher von den Feldmessgeräten nur von der Stranggießkokille oder von dem Ventilstand in die Steuerungsschaltung des Steuerhauses geführt werden. Die Distanz zur Steuerschaltung im Steuerhaus ist nach wie vor sehr hoch und von jeder Stranggießkokille sind Daten von vier Positionsgebern, von vier Rege- lungsventilen in vier synchron-seriellen Schnittstellen und 12 Analogsignale zu verarbeiten.For the adjustment of a hinged to the narrow side plate piston rod or a hydraulic cylinder, various signals that arise in the vicinity of the hydraulic cylinder or must be implemented to electrically connect to a control circuit. The person responsible for hiring The necessary valve stand is generally arranged on the hall scaffolding in the area of the casting platform or below it (on the so-called mainland). The control is normally installed in the area of the casting platform in the control room. It is important for the field devices in the area of the continuous casting mold that a separation is present because the continuous casting mold has to be quickly removed and reinstalled. The measurement data can therefore be guided by the field measuring devices only from the continuous casting mold or from the valve position in the control circuit of the wheelhouse. The distance to the control circuit in the wheelhouse is still very high and of each continuous casting mold data from four position sensors, four control valves in four synchronous serial interfaces and 12 analog signals to process.
Der Erfindung liegt die Aufgabe zugrunde, die Messdaten im Bereich der Stranggießkokille in gekühlten Feldgeräten zu erfassen und vor Ort schon zu verarbeiten.The object of the invention is to record the measured data in the area of the continuous casting mold in cooled field devices and to process them on site.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Hydraulikzylinder der Kolben-Zylinder-Einheiten jeweils an einen im Bereich der Stranggießkokille oder der Stranggießsteuerung angeordneten Ventilstand mit einem ortsfesten Klemmenkasten für die Mess- und Steuersignalleitungen angeschlossen ist und dass der Klemmenkasten mit einem Achsen-Regler verbunden ist, von dem das Feldbus-Modul die Signale zu einer speicherprogrammierbaren Steuerung führt. Vorteile ergeben sich durch einen geringeren Verkabelungsaufwand bei kürzeren Abständen zwischen den Baugruppen. Der Hauptvorteil ist jedoch der Achsen-Regler. Die Achsenregler 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:The stated object is achieved according to the invention in that the hydraulic cylinder of the piston-cylinder units is connected in each case to a valve stand arranged in the region of the continuous casting mold or the continuous casting control with a stationary terminal box for the measuring and control signal lines and the terminal box is connected to an axis regulator from which the fieldbus module leads the signals to a programmable logic controller. Advantages result from a lower cabling effort with shorter distances between the modules. The main advantage, however, is the axis controller. The axis controllers are special microprocessor-based circuits used to control servo axes. The standard software in motion control adds a real-time control for axis adjustment. The motion control has, for example, interfaces for:
Maschinen- oder Schritt-Positions-Wandler, - Digital- oder Analog- Ein oder Ausgänge, einen Profibus, ein Netzwerk.Machine or step position transducer, - digital or analog inputs or outputs, a Profibus, a network.
Die für die Anwendung eingesetzte Bewegungs-Steuerung umfasst eine Fern- bedienung und eine Datenanzeigeeinrichtung ( Display). Die Anwendungs- Software ist Standard und ist in einem wieder aufrufbaren Speicher gespeichert. Die Bewegungs-Steuerung ist in der Lage, mehrere Achsen ( hydraulische Kolben-Zylinder-Einheiten) zu steuern. Auf einem grafischen Menü basierend, wird die Bewegungs-Steuerung über Parameter an den Achsen-Typ angepasst und an den Typ der Positions-Rückkopplung. Ein Programmieren ist nicht notwendig. Über den Feldbus-Leitungsanschluss erhält die Bewegungs-Steuerung die erforderlichen Sollwerte und die Start-Bewegung und koppelt diese auf das ü- bergeordnete System mit der Position und einer Zustandsanzeige zurück. Weitere Vorteile ergeben sich dadurch, dass die Übertragung der Daten zwischen der speicherprogrammierbaren Steuerung und dem Achsen-Regler zeitlich unkritisch und sicher ist.The motion control used for the application comprises a remote control and a data display device (display). The application software is standard and stored in a recallable memory. The motion control is able to control multiple axes (hydraulic piston-cylinder units). 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 line connection and links these back to the higher-level system with the position and a status display. Further advantages result from the fact that the transmission of data between the programmable logic controller and the axis controller is time-critical and safe.

Material costs and installation and time wiring costs can be reduced. The electrical susceptibility is reduced. Likewise, the maintenance is reduced. Times for assembly and commissioning are reduced.
Die Montage und die Wartung der Elektronik werden dadurch vereinfacht, dass die speicherprogrammierbare Steuerung mittels einer lösbaren Steckverbin- düng bei entsprechender Kontaktanzahl an das Feldbus-Modul angeschlossen ist.The assembly and maintenance of the electronics are simplified in that the programmable logic controller is connected by means of a detachable connector fertil with a corresponding number of contacts to the fieldbus module.
Ebensolche Vorteile werden ferner nach einer anderen Ausgestaltung dadurch erzielt, dass in den Hydraulikzylindern jeweils integrierte Positionsgeber über die Steckverbindung mit dem Ventilstand am Hallen-Gerüst verbunden sind. In der Nähe der Heißzone befindliche Baugruppen werden nach weiteren Merkmalen dadurch geschützt, dass der Klemmenkasten im Bereich der Stranggießkokille im Inneren gekühlt ist.Similar advantages are also achieved according to another embodiment, characterized in that in the hydraulic cylinders each integrated position sensor are connected via the connector to the valve stand on the hall scaffold. In the vicinity of the hot zone assemblies are protected according to further features in that the terminal box is cooled in the region of the continuous casting mold inside.
Für die Kühlung ist allgemein vorgesehen, dass als Kühlmittel entweder Luft oder von der Stranggießkokille abgeleitetes Kühlwasser verwendet wird.For cooling, it is generally provided that either air or cooling water derived from the continuous casting mold is used as the coolant.
Eine Weiterbildung sieht vor, dass die BUS-Leitung und das Feldbus-Modul sowie Mess- und Steuersignalleitungen physikalisch aus Lichtwellenleitern oder drahtloser Übertragung oder Infrarot-Technik gebildet ist.A further development provides that the BUS line and the field bus module as well as measuring and control signal lines are formed physically from optical waveguides or wireless transmission or infrared technology.
