Description

Verfahren und Einrichtung zur dezentralen Gießdatenverarbeitung der an einer Stranggießkokille über Sensoren gewonnenen MessdatenMethod and device for decentralized casting data processing of the measurement data obtained on a continuous casting mold via sensors
Die Erfindung betrifft ein Verfahren und eine Einrichtung zur dezentralen Gießdatenverarbeitung der an einer Stranggießkokille über Sensoren gewonnenen Messdaten in einem Prozessrechner der Steuerung der Stranggießanlage.The invention relates to 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 the control of the continuous casting plant.
In Stranggießanlagen werden an der Stranggießkokille horizontale Reihen von Thermoelementen und Widerstands-Thermoelementen angeordnet, deren Thermoleitungen mit jeweils zwei Anschlüssen über Klemmenkästen auf ein sog. Stammkabel geführt sind. Bei z.B. 60 Thermoelementen und 40 Wider- stands-Thermoele-menten fallen 240 Thermoleitungen an, die alle zum Stammkabel geführt werden müssen.In continuous casting plants, horizontal rows of thermocouples and resistance thermocouples are arranged on the continuous casting mold, the thermal lines of which are each connected to terminal boxes on a so-called master cable. With e.g. 60 thermocouples and 40 resistance thermocouples result in 240 thermo lines, all of which must be routed to the master cable.
Zunächst verlaufen die Thermoleitungen zu Messwertaufnehmern. Das Stammkabel ist mit einer sog. Multikupplung (Kupplung und Gegenkupplung) an eine Energieversorgung außerhalb der oszillierenden Stranggießkokille am starren Teil der Stranggießanlage, dem sog. "Festland" angeschlossen. Alle Thermoleitungen, Klemmenkästen und das Stammkabel sind einer Temperatur von ca. 60 - 100 eC ausgesetzt. Hinzu kommt neben der Hitze eine im Gießbetrieb nicht vermeidbare Verschmutzung, z.B. durch Schlackespritzer, und außerdem tritt Feuchtigkeit auf. Da die Thermoelemente und Widerstands-Thermoelemente mit Spannungen im 10 - 500 mV - Bereich arbeiten, wirken sich außerdem elektromagnetische Felder anderer Organe an der Stranggießkokille aus. Diese Gestaltung bedingt für diverse Einheiten auf der Stranggießkokille (z.B. den VerStellantrieb für die Schmalseitenplatten, für Weggeber, Remote- Stationen für Temperaturmessstellen etc.) erhöhte Wechselzeiten, einen hohen Montageaufwand und einen hohen Installations- und Verkabelungsaufwand, hohe Materialkosten und einen hohen Wartungsaufwand. Zum Stand der Technik gehört eine Vorrichtung zur Bestimmung des Schmelzenspiegels in einer Stranggießkokille (DE - OS 26 55 640). Diese Bauweise sieht jedoch lediglich Mittel zur abnehmbaren Montage eines Detektorkastens im Wassermantel der Stranggießkokille und Kühlwasser-Einlass- und Auslassmittel im Detektorkasten zur Führung von Kühlwasser durch den Detektorkasten zwecks Kühlung der in ihn eingebauten elektromagnetischen Spule mit Schutzgehäuse vor. Diese Lösung kann daher nicht auf an der Stranggießkokille angeordnete Thermoelemente und Widerstands-Thermoelemente angewendet werden. Dabei ist das Messverfahren auch andersartig gestaltet.First, the thermal lines run to sensors. The master cable is connected to a power supply outside the oscillating continuous casting mold on the rigid part of the continuous casting plant, the so-called "mainland", with a so-called multi-coupling (coupling and counter-coupling). All thermal lines, terminal boxes and the master cable are exposed to a temperature of approx. 60 - 100 e C. In addition to the heat, there is contamination that cannot be avoided in the casting plant, for example from slag splashes, and moisture also occurs. Since the thermocouples and resistance thermocouples work with voltages in the 10 - 500 mV range, electromagnetic fields from other organs also have an effect on the continuous casting mold. For various units on the continuous casting mold (e.g. the adjustment drive for the narrow side plates, for position sensors, remote stations for temperature measuring points, etc.), this design means increased change times, a high level of assembly work and a high level of installation and cabling costs, high material costs and high maintenance costs. The prior art includes a device for determining the melt level in a continuous casting mold (DE-OS 26 55 640). However, this design only provides means for the detachable mounting of a detector box in the water jacket of the continuous casting mold and cooling water inlet and outlet means in the detector box for guiding cooling water through the detector box in order to cool the electromagnetic coil with protective housing built into it. This solution can therefore not be applied to thermocouples and resistance thermocouples arranged on the continuous casting mold. The measuring process is also designed differently.
Der Erfindung liegt die Aufgabe zugrunde, auf elektronischem Weg u.a. die über Sensoren gemessenen Gießdaten auf effizienteren Wegen zu verarbeiten und dadurch auch die Einrichtung zu vereinfachen.The invention is based, inter alia, electronically. Process the casting data measured by sensors in a more efficient way and thereby also simplify the set-up.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass 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. Dadurch wird der Datenweg erheblich verkürzt und vereinfacht und auch die Einrichtung wird, wie nachstehend noch genauer aufgezeigt wird, vereinfacht. Vorteilhaft ist insbesondere, dass nur noch der Anschluss an einem auf dem "Festland" befindlichen Klemmenkasten zu lösen oder zu verbinden ist, so dass die Wechselzeiten erheblich sinken, der Installations- und Verkabelungsaufwand reduziert wird, die Materialkosten gesenkt werden, der Wartungsaufwand vermindert wird und dadurch das Ausbringen an Stahl erheblich gesteigert werden kann. Die Datenverarbeitung kann auch im Feldbus-Modul selbst oder sogar über eine internet-Verbindung mit globalem Anschluss erfolgen. Dabei können Daten erfasst werden von Sensoren oder Aktoren, nämlich von Drehgebern, Winkelmessgebern (sog. Inklinometern), Pumpen, Durchflussmessern, steuerbaren Ventilen, Elektromotoren u. dgl.. In Ausgestaltung der Erfindung ist vorgesehen, dass die aufgenommenen Messdaten oder zusätzlich eingegebene spezifische Daten über die Bus- Leitungen als Steuersignale an Stellorgane und / oder Aktoren im Bereich der Stranggießkokille gegeben werden. Dadurch kann das System auch aktiv zur Steuerung oder Regelung des Gießprozesses eingesetzt werden.The object is achieved according to the invention in that the measurement and control data are collected in cooled fieldbus modules 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 simplifies the setup, as will be shown in more detail below. It is particularly advantageous that only the connection to a terminal box located on the "mainland" has to be disconnected or connected, so that the changeover times decrease considerably, the installation and cabling work is reduced, the material costs are reduced, the maintenance work is reduced and the output on steel can be increased considerably. Data processing can also take place in the fieldbus module itself or even via an internet connection with a global connection. Data can be recorded by sensors or actuators, namely by rotary encoders, angle encoders (so-called inclinometers), pumps, flow meters, controllable valves, electric motors and the like. etc. .. In an embodiment of the invention, it is provided that the recorded measurement data or additionally entered specific data are sent via the bus lines as control signals to actuators and / or actuators in the area of the continuous casting mold. As a result, the system can also be used actively to control or regulate the casting process.
Ein weiterer Vorteil ergibt sich dadurch, dass in den Feldbus-Modulen auf der Stranggießkokille kokillenspezifische Informationen über die Kupferplattendicke, den Abnutzungsgrad, den Zustand der Thermo-Sensoren und / oder der Wider- stands-Thermosensoren und die Wartungszyklen abrufbar gespeichert sind.Another advantage results from the fact that in the fieldbus modules on the continuous casting mold, mold-specific information about the copper plate thickness, the degree of wear, the state of the thermal sensors and / or the resistance thermal sensors and the maintenance cycles are stored.
Eine Weiterentwicklung der Erfindung sieht vor, dass der Datenaustausch und die Energieversorgung zumindest zwischen den Feldbus-Modulen und dem Prozessrechner über eine Hybridkopplung vorgenommen wird. Dadurch können sowohl Datenströme als auch Energieströme in einem elektrischen Leiter geführt werden.A further development of the invention provides that the data exchange and the energy supply is carried out at least between the fieldbus modules and the process computer via a hybrid coupling. As a result, both data streams and energy streams can be carried in an electrical conductor.
In Ausgestaltung ist vorgesehen, dass die Hybridkopplung aus einem Kommunikationsbus und einer Energieversorgung gebildet wird. Die gesamten Ströme laufen dabei über ein einziges Hybridkabel.One embodiment provides that the hybrid coupling is formed from a communication bus and an energy supply. The entire currents run on a single hybrid cable.
Von Vorteil ist weiter, dass die Hybridkopplung in Anwesenheit eines Kühlmediums betrieben wird. Dabei kann zur Kühlung auch das Stranggießkokillen- Kühlwasser herangezogen werden. Es ist auch möglich, ein fremd zugeführtes Kühlmittel (Gas oder Flüssigkeit) einzusetzen.Another advantage is that the hybrid coupling is operated in the presence of a cooling medium. The continuous casting mold cooling water can also be used for cooling. It is also possible to use an externally supplied coolant (gas or liquid).
Die Einrichtung für die dezentrale Gießdatenverarbeitung der an einer Stranggießkokille über Sensoren gewonnenen Messdaten in einem Prozessrechner der Steuerung der Stranggießanlage löst die gestellte Aufgabe erfindungsgemäß dadurch, dass unmittelbar an der Stranggießkokille mehrere, mit den Sensoren und / oder Aktoren verbundene Feldbus-Module angebaut und mit einer Kühlung versehen sind. Dadurch können alle Sensoren auf der Stranggießko- kille unmittelbar über eine kurze Signalführung auf dezentrale Messwertaufnehmer verkabelt werden. Solche Feldbus-Module befinden sich dann unmittelbar in Sensornähe.The device for the decentralized casting data processing of the measurement data obtained on a continuous casting mold via sensors in a process computer of the control of the continuous casting system achieves the object according to the invention in that several fieldbus modules connected to the sensors and / or actuators are attached directly to the continuous casting mold and with one Cooling are provided. This means that all sensors on the continuous casting kille can be wired directly to a decentralized sensor using a short signal routing. Such fieldbus modules are then located close to the sensor.
Für die Kühlung werden verschiedene Varianten geschaffen. So ist nach einem einfachen Vorschlag vorgesehen, dass die Feldbus-Module mittels des vorhandenen Stranggießkokillen-Kühlmittelflusses kühlbar sind. Dadurch wird ein minimaler zusätzlicher Aufwand erreicht.Different variants are created for cooling. According to a simple proposal, it is provided that the fieldbus modules can be cooled by means of the existing continuous mold coolant flow. This results in minimal additional effort.
Eine andere Variante sieht vor, dass die Feldbus-Module in einem gekühlten Schutzgehäuse eingeschlossen sind. Hier ist eine Fremdkühlung unter Aus- schluss von Feuchtigkeit in dem zugeführten Kühlmedium zweckmäßig.Another variant provides that the fieldbus modules are enclosed in a cooled protective housing. In this case, external cooling with the exclusion of moisture in the cooling medium supplied is expedient.
Der Zutritt von Feuchtigkeit und eine Unabhängigkeit des Feuchtigkeitsgehaltes von Luft kann nach weiteren Merkmalen dadurch erreicht werden, indem in dem Schutzgehäuse ein Klimatisierungsgerät zur Kühlung miteingebaut ist.According to further features, the access of moisture and independence of the moisture content from air can be achieved in that an air conditioning unit for cooling is installed in the protective housing.
Eine andere Verbesserung der Erfindung besteht darin, dass der Kommunikationsbus physikalisch aus elektrischer oder elektronischer Leitungstechnik, Lichtwellenleitertechnik oder drahtloser Übertragungstechnik gebildet ist.Another improvement of the invention is that the communication bus is physically formed from electrical or electronic line technology, optical fiber technology or wireless transmission technology.
Weiterhin ist vorgesehen, dass die drahtlose Übertragungstechnik aus einer Funkübertragung besteht oder aufgrund von Infrarotstrahlung gebildet ist.Furthermore, it is provided that the wireless transmission technology consists of a radio transmission or is formed on the basis of infrared radiation.
Eine andere Weiterentwicklung der Erfindung sieht vor, dass mittels des Kühlmittelflusses in der Stranggießkokille ein Generator antreibbar ist, der elektrisch betriebene Organe auf der Stranggießkokille versorgt. Die Energiezuführung für den Generator besteht in der Strömungsenergie des Kühlwassers.Another further development of the invention provides that by means of the coolant flow in the continuous casting mold, a generator can be driven which supplies electrically operated organs on the continuous casting mold. The energy supply for the generator consists of the flow energy of the cooling water.
Eine Variante hierzu besteht darin, dass die Antriebsbewegung für den Generator aus der Stranggießkokillen-Oszillationsbewegung ableitbar ist. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung näher dargestellt und wird nachstehend erläutert.A variant of this is that the drive movement for the generator can be derived from the continuous casting mold oscillation movement. In the drawing, an embodiment of the invention is shown in more detail and is explained below.

Widerstands-Thermosensoren 10 gewonnenen Messdaten in einem Prozessrechner 11 mit einem Redundanzanschluss 11a der Steuerung der Stranggießanlage (Fig. 1), wird derart ausgeübt, dass die von einer Vielzahl von verteilt auf der Stranggießkokille 1 angeordneten Thermosensoren und / oder Widerstands-Thermosensoren 10 gewonnenen Messdaten in einem gekühlten Feldbus-Modul 2 unmittelbar auf der Stranggießkokille 1 gesammelt und als Bus-Signale in eine Bus-Leitung 3 überführt und in der Steuerung der Stranggießanlage gespeichert und verarbeitet werden. Dabei können auch die aufgenommenen Messdaten oder zusätzlich eingegebene, spezifische Daten über die einzige Bus-Leitung 3 als Steuersignale an Stellorgane und / oder Aktoren im Bereich der Stranggießkokille 1 gegeben werden. Als Stellorgane kommen z.B. die Kupferplatten 4 in Form der Schmalseitenplatten und die Aktoren als ihre zugehörigen Antriebe in Betracht. Die kokillenspezifischen Informationen betreffen z.B. die Kupferplattendicke, den Abnutzungsgrad, den Zustand der Thermosensoren oder der Widerstands- Thermosensoren 10, sowie die Wartungszyklen.The process for decentralized casting data processing of the measurement data obtained on a continuous casting mold 1 via thermal sensors or resistance thermal sensors 10 in a process computer 11 with a redundancy connection 11a of the control of the continuous casting system (FIG. 1) is carried out in such a way that the data are distributed among a large number of The measurement data obtained from the continuous casting mold 1 and the thermal sensors and / or resistance thermal sensors 10 are collected in a cooled fieldbus module 2 directly on the continuous casting mold 1 and transferred as bus signals to a bus line 3 and stored and processed in the control of the continuous casting system. The recorded measurement data or additionally entered, specific data can also be sent as control signals to actuators and / or actuators in the area of the continuous casting mold 1 via the single bus line 3.

Gemäß Fig. 1 findet der Datenaustausch über die Bus-Leitungen 3 und einen Klemmenkasten 5 mit Transformator zwischen den Feldbus-Modulen 2 und dem Prozessrechner 11 über eine Hybridkopplung statt. Die Hybridkopplung bildet ein Hybridkabel 6 mit einem Kommunikationsbus 7 und einer Energieversorgung. Das Hybridkabel 6 kann ebenfalls unter einer Kühlung 8 wie die Feldbus-Module 2 betrieben werden. Grundsätzlich kann als Kühlung 8 für die Feldbus-Module 2 der vorhandene Stranggießkokillen-Kühlmittelfluss 8a eingesetzt werden.1, the data exchange takes place via the bus lines 3 and a terminal box 5 with a transformer between the fieldbus modules 2 and the process computer 11 via a hybrid coupling. The hybrid coupling forms a hybrid cable 6 with a communication bus 7 and a power supply. The hybrid cable 6 can also be operated under cooling 8 like the fieldbus modules 2. In principle, the existing continuous casting mold coolant flow 8a can be used as the cooling 8 for the fieldbus modules 2.
Die Feldbus-Module 2 sind von einem gekühlten Schutzgehäuse 9 umgeben. In dem Schutzgehäuse 9 ist, falls erforderlich, ein gesondertes Klimatisierungsgerät 12 eingebaut (Fig. 2 und 3). Das Schutzgehäuse 9 liegt auf der Stranggießkokille 1 bzw. auf dem Wasserkasten 19 auf, so dass die Feldbus-Module 2 in kürzestem Abstand zu den Thermosensoren 10 liegen und von dem Kühlmittel- fluss 8a und / oder dem Klimatisierungsgerät 12 gekühlt werden. Dasselbe gilt für die Thermoleitungen 15, die in Kabeldurchführungen 14 von den Thermosensoren 10 in die Feldbus-Module 2 geführt sind.The fieldbus modules 2 are surrounded by a cooled protective housing 9. If necessary, a separate air conditioning unit 12 is installed in the protective housing 9 (FIGS. 2 and 3). The protective housing 9 rests on the continuous casting mold 1 or on the water tank 19, so that the fieldbus modules 2 are located at the shortest distance from the thermal sensors 10 and are cooled by the coolant flow 8a and / or the air conditioning device 12. The same applies to the thermal lines 15, which are guided in the cable bushings 14 from the thermal sensors 10 into the fieldbus modules 2.
