Description
Die Erfindung betrifft ein Verfahren zur Überwachung des individuellen Prozeßverlaufs von Transportbehältern für metallische Schmelze, insbesondere des Prozeßverlaufs zwischen dem Schmelzaggregat und der Gießstation, sowie ein System hierzu.The invention relates to a method for monitoring the individual process flow of transport containers for metallic melt, in particular of the course of the process between the smelting unit and the casting station, as well as a system For this.
Transportbehälter für metallische Schmelze dienen als Überbrückungsmittel der Wege zwischen Schmelzaggregat, beispielsweise einem Elektrolichtbogenofen oder Konverter, und der Gießstation, beispielsweise einer Stranggießanlage. Die metallurgische Nachbehandlung von Stahl wird in der heutigen Zeit weniger im Schmelzaggregat, sondern weitgehend in der Gießpfanne in nachgeschalteten sekundärmetallurgischen Behandlungsstationen vorgenommen. Nach Entleeren der Schmelze in den Verteiler der Stranggießanlage gelangt die Gießpfanne - evtl. nach einer kurzen Heißreparatur - zurück zu ihrem Ausgangspunkt, und ein neuer Arbeitszyklus beginnt.Transport container for metallic melt serve as bridging the Routes between melting unit, such as an electric arc furnace or converter, and the casting station, for example a continuous caster. The metallurgical aftertreatment of steel is less in the modern day Melting unit, but largely in the ladle in downstream made of secondary metallurgical treatment stations. After emptying the melt enters the distributor of the continuous casting plant the ladle maybe after a short hot repair - back to their starting point, and a new work cycle begins.
Derartige Pfannen sind mit Feuerfestmaterial ausgemauert, um die Schmelze beim Transport zu isolieren und somit einen geringen Wärmeverlust insbesondere während der relativ langen Gieß- und Hängezeiten an der Gießstation zu gewährleisten. In Abhängigkeit des Verschleißgrades des Feuerfestmaterials kommt es zu einer Erhöhung des Wärmeverlustes der Pfanne, wobei dieser Wärmeverlust beim Gießprozeß ermittelt und durch Einbringen von Überhitzungsenergie in die Schmelze ausgeglichen werden muß. Such pans are lined with refractory material to the melt to isolate during transport and thus a low heat loss in particular during the relatively long casting and hanging times at the casting station to ensure. Depending on the degree of wear of the refractory material occurs to increase the heat loss of the pan, this heat loss determined during the casting process and by introducing superheating energy in the Melt must be balanced.
Derartige Verschleißprozesse sind individuell abhängig von der Anzahl der Arbeitszyklen, aber auch von der jeweiligen Prozessroute jeder Pfanne, die bestimmt wird von den Verweilzeiten des Stahls in der Pfanne als Folge von Transportzeit, Wartezeiten zwischen den Prozessstufen oder den Behandlungszeiten innerhalb der Prozessstufen. Auch die Behandlungstemperaturen nehmen Einfluss auf den Verschleißgrad.Such wear processes are individually dependent on the number of work cycles, but also from the respective process route of each pan that determines is determined by the residence times of the steel in the pan as a result of transport time, Waiting times between the process stages or the treatment times within the process stages. The treatment temperatures also influence the Degree of wear.
Ausgehend von diesen Daten können Rückschlüsse gezogen werden auf den Zustand der Feuerfestausmauerung und somit auf den spezifischen Wärmeverlust der Pfanne. In Abhängigkeit davon wird die notwendige Temperatureinbringung in die Schmelze vor dem Gießen berechnet. Zudem ist in Abhängigkeit der Anzahl der Arbeitszyklen sowie der Überwachung des individuellen Prozessverlaufs der Zeitpunkt für die Neuzustellung der Pfanne mit Feuerfestmaterial bestimmbar.Based on these data conclusions can be drawn on the condition the Feuerfestausmauerung and thus on the specific heat loss the pan. Depending on this, the necessary temperature input in the melt is calculated before pouring. In addition, depending on the number the working cycles and the monitoring of the individual course of the process Date for the new delivery of the pan with refractory material determinable.
Bisher ist es üblich, die individuellen Daten, die die Route einer bestimmten Pfanne ausmachen, durch Bedienungsmaterial an den jeweiligen Prozessstufen manuell aufzunehmen und dann Rückschlüsse auf die oben genannten Faktoren zu ziehen. Diese Vorgehensweise ist personalaufwendig und fehlerträchtig.So far, it is common to have the individual data representing the route of a particular pan manually, through operating material at the respective process stages and then draw conclusions about the factors mentioned above pull. This procedure is labor intensive and error prone.
Die PAJ-62 252 663 beschreibt ein Verfahren und eine Anlage zur Überwachung von Transportbehältern für geschmolzenes Metall entlang eines Prozessweges. Es bleibt aber offen, ob die Pfannen individuell erfasst werden oder ob nur beispielsweise in der Füll- bzw. Gießposition über der Kokille das Vorhandensein einer Pfanne registriert wird.The PAJ-62 252 663 describes a method and a system for monitoring transport containers for molten metal along a process path. However, it remains unclear whether the pans are recorded individually or if only for example in the filling or casting position above the mold the presence of a Pan is registered.
Eine solche Anlage und ein solches Verfahren sind auch durch die EP-A-0 027 237 bekannt geworden. Zur Identifizierung von Gießformeinheiten entlang einer Gießstraße weisen die Gießformen eine Kodiervorrichtung auf, die in verschiedenen Stationen von einem Lesegerät gelesen oder abgetastet werden kann. Hiervon ausgehend liegt der Erfindung demnach die Aufgabe zugrunde, ein Verfahren und ein System gattungsgemäßer Art zu schaffen, mit dem eine Überwachung des individuellen Prozessverlaufs eines jeden Transportbehälters automatisch erfolgt.Such a plant and method are also disclosed by EP-A-0 027 237 become known. For identification of mold units along a Gießstraße, the molds on a coding device, which in different Stations can be read or scanned by a reader. On this basis, the invention is therefore based on the object, a method and to provide a system of the generic type with which monitoring the individual process of each transport container automatically he follows.
Hierzu wird verfahrensgemäß vorgeschlagen, dass jeder einzelne Transportbehälter automatisch identifiziert wird durch Ermittlung der Daten mindestens eines an jedem Transportbehälter angebrachten individuellen Informationsträgers bei der Vorbeibewegung des Transportbehälters an mindestens einer, bevorzugt mehreren, ortsfest angeordneten Stationen entlang der Prozessroute, sowie dem selbständigen Weiterleiten dieser kombinierten Ort-Behälter-Informationen an ein Auswertesystem zur rechnergestützten Ermittlung der Transportbehälterlogistik und der Parameter für nachfolgende Prozesse.For this purpose, it is proposed according to the procedure that each individual transport container automatically identified by determining the data of at least one each transport container attached individual information carrier in the Passing the transport container to at least one, preferably several, stationarily arranged stations along the process route, as well as the independent Forwarding this combined location container information to a Evaluation system for computer-aided determination of transport container logistics and the parameter for subsequent processes.
Die aufgenommenen Daten von einen Behälter an einem bestimmten Ort dienen als Datenbasis für ein Rechnermodell. Hier wird über den individuellen Prozeßverlauf und Abfolge von Zeiten rechnerisch beispielsweise der Zustand der Feuerfestausmauerung des Transportbehälters bzw. der spezifische Wärmeverlust der Pfanne bestimmt und in Abhängigkeit hiervon die Parameter für nachfolgende Prozesse, insbesondere die Einstellung der Überhitzungstemperaturen beim Gießen jeder Schmelze und der Zeitpunkt der Neuzustellung des Transportbehälters mit Feuerfestmaterial, ermittelt.The recorded data will serve from a container to a specific location as a database for a computer model. Here is about the individual process history and sequence of times, for example, the state of the refractory lining of the transport container or the specific heat loss the pan determines and depending thereon the parameters for subsequent Processes, in particular the setting of overheating temperatures during casting each melt and the time of re-delivery of the transport container with refractory material, determined.
Das vorgeschlagene System umfaßt hierzu individuelle Informationsträger, mit denen die jeweiligen Transportbehälter zu ihrer Identifizierung versehen sind, mindestens eine Station, die entlang der Prozeßroute der Transportbehälter angeordnet ist - vorzugsweise an den jeweiligen Behandlungsstationen der Schmelze -, wobei diese Stationen mit Mitteln versehen sind zur Ermittlung der Daten, die sich auf den Informationsträgern der Transportbehälter befinden, wobei sich die Transportbehälter mit einem vorgegebenen Abstand an den Stationen vorbeibewegen oder beabstandet hierzu für einen bestimmten Zeitraum warten, sowie mit Mitteln zur selbständigen Weiterleitung dieser Informationen an rechnergestützte Auswertesysteme.The proposed system includes this individual information carrier, with which the respective transport containers are provided for their identification, at least a station, which is arranged along the process route of the transport container is - preferably at the respective treatment stations of the melt -, these stations being provided with means for determining the data which is located on the information carriers of the transport container, wherein the transport container pass the stations with a given distance or spaced to wait for a certain period of time, as well as with funds for independently forwarding this information to computer-aided evaluation systems.
Nach einer ersten bevorzugten Ausführungsform des Systems weisen die Transportbehälter
selbst die Mittel zur Übertragung von - kodierten - Daten an die jeweiligen
Stationen auf, vorzugsweise in Form von Transpondern nach Anspruch 5.
Insbesondere wird ein Transponder auf Basis von Mikrowellen vorgeschlagen. Die
Identifikationsdaten werden im Transponder, der am Transportbehälter angeordnet
ist, gespeichert und bei Annäherung an die jeweilige Station zu dieser übertragen.
Der Abstand zwischen Transportbehälter und Station kann zwischen 3 und
10 m betragen. Sowohl der Transponder als auch die Station sind mit einem den
rauhen Umgebungsbedingungen angepaßten thermischen und mechanischen
Schutz versehen.According to a first preferred embodiment of the system, the transport containers

Stations, preferably in the form of transponders according to
Nach einer zweiten Ausführungsform des erfindungsgemäßen Systems sind die

Denkbar sind hier beispielsweise auch Strichcodierungen, die von Kameras
an den Stationen gelesen werden. Eine bevorzugte Ausführungsform als
thermische Musterauswertung wird in den Ansprüchen 5 bis 7 vorgeschlagen.According to a second embodiment of the system according to the invention are

Figur 1 zeigt eine Gießstation 1 mit zwei Gießpfannen 2a, 2b, die an einem gemeinsamen
Pfannendrehturm 3 für einen Sequenzgießprozeß aufgehängt sind.
Der Pfannendrehturm ermöglicht die genaue und schnelle Positionierung der jeweiligen
Pfanne über dem Verteiler 4. Über den Verteiler 4 bzw. über ein Tauchrohr
5 fließt Schmelze 6 in die unterhalb des Verteilers angeordnete Kokille 7 zur
Formgebung der Schmelze als Bramme, Knüppel etc.Figure 1 shows a casting station 1 with two
An ihrer Außenfläche bzw. Mantel ist jede Gießpfanne 2a, 2b mit einem Mikrowellen-Transponder
8 versehen. Es handelt sich um eine Sende- und Empfangseinrichtung,
die nach einer empfangenen und ausgewerteten Anfrage von einer
Station, hier mit 9 bezeichnet, eine Antwort im Umfang der jeweiligen gespeicherten
Behälterdaten an diese erteilt. Die Kommunikation zwischen Transponder 8
und Station 9 mit entsprechendem Anfragesystem ist hier über ein Strahlenbündel
10 sichtbar gemacht. Durch die Identifizierung der jeweiligen Pfanne werden auf
Basis der im Prozeßverlauf gesammelten Daten Rückschlüsse beispielsweise auf
den Verschleißgrad der Feuerfestmaterialzustellung der Pfanne gezogen und
mittels eines Rechnermodells die notwendigen Schmelzetemperaturen für eine
sichere Gießtemperatur berechnet und beim Abstich im Schmelzaggregat eingestellt.On its outer surface or shell, each
Bei einer zweiten Ausführungsform (Figur 2) liest eine Thermokamera 11 ein individuelles
thermisches Muster aus. Hierzu wird an den Pfannenmantel 12 in einem
Abstand von etwa 100 mm mit Hilfe von Befestigungselementen 13a, 13b eine
Platte 14 - beispielsweise mit Abmessungen von 1200 mm Höhe und 500 mm
Breite - angebracht. Die Platte selbst ist aus Feuerfestmaterial gefertigt. Um durch
natürliche Konvektion der vorbeistreichenden Luft eine Verminderung der Plattenoberflächentemperatur
zu erhalten, ist die Platte an ihrer vom Pfannenmantel
abgewandten Seite mit gerippten metallischen Elementen 15 versehen. Hierdurch
werden Oberflächentemperaturen der Platte zwischen 80 und 100°C erreicht,
während der Pfannenmantel Oberflächentemperaturen von etwa 200°C aufweist.In a second embodiment (FIG. 2), a thermal camera 11 reads an individual one
thermal pattern. For this purpose, the
Eine solche Platte 14 ist mit einem für jeden Behälter individuellen Muster vorsehen
(Figuren 3 und 4). Mittels der Thermokamera wird das jeweilige thermische
Muster ausgelesen, wenn sich eine Pfanne in der Nähe einer Thermokamera befindet,
die an den jeweiligen Prozeßstationen angeordnet sind, beispielsweise der
Schmelzstation, der Station zur Sekundärbehandlung der Schmelze sowie der
Gießstation entsprechend Figur 1. Das aufgenommene thermische Muster wird
von dieser Kamera 11 an ein Auswertesystem 16 weitergeleitet, in das die Ergebnisse
der anderen Muster der verschiedenen Stationen ebenfalls eingehen, hier
mit 17 bezeichnet. Mittels eines Rechnermodells werden diese Muster verarbeitet,
und aus den gewonnenen Daten Rückschlüsse auf beispielsweise den Zeitpunkt
der nächsten Feuerfestzustellung der Pfanne gezogen oder die Einstellungen für
weitere Prozesse ausgerechnet und als Stellgröße (18) an die entsprechenden
Vorrichtungen gegeben, beispielsweise an das Schmelzaggregat zur Einstellung
der entsprechenden Überhitzungstemperaturen. Diese Datenbasis ist nicht nur zur
Verwendung der Berechnungen für Neuzustellungen der Pfannen und Berechnungen
der Überhitzungstemperaturen beschränkt. Denkbar ist die Berechnung
aller Größen, die in die Pfannenlogistik eingehen. Wird beispielsweise ein Ausfall
einer der Pfannen beobachtet, kann der Prozeßverlauf der anderen Pfannen koordiniert
und an die neue Situation angepaßt werden.Such a
Die Figuren 3 und 4 zeigen jeweils eine Platte 114, 214, die als Informationsträger
bei der thermischen Musterauswertung dient. Die Platte 114 nach Figur 3 weist ein
vorgerastertes Muster 115 auf, wobei durch die unterschiedliche Wahl von Durchbrüchen
- hier wird beispielhaft nur ein Durchbruch mit 116 bezeichnet - ein individuelles
Muster entsteht, das jeweils für eine Pfanne charakteristisch ist. Die Platte
nach Figur 3 ist dadurch gekennzeichnet, daß ihr Muster in der ersten und vierten
Zeile von oben jeweils in der rechten Spalte keinen Durchbruch aufweist. Die linke
Spalte jeder Platte weist in jedem perforierten Fenster Durchbrüche auf und dient
als Referenzspalte 117, 217. Die Platte nach Figur 4 ist in dieser Gegenüberstellung
nicht individualisiert. Derart an dem Pfannenmantel befestigt, erlauben diese
Platten die Sicht auf den Pfannenmantel durch die jeweiligen Durchbrüche. Eine
an den Stationen angebrachte Thermokamera erkennt bei Annäherung einer
Pfanne ein thermisches Muster, welches sich aus heißen Bereichen und kühleren
Bereichen zusammensetzt, je nachdem, ob der jeweilige Durchbruch den Blick auf
den Pfannenmantel zuläßt.FIGS. 3 and 4 each show a
Das aktuell aufgenommene Videobild wird - wie in Figur 2 beschrieben - einem Auswertesystem zugeführt. Zum einen wird anhand der Anzahl und Anordnung der Durchbrüche in der Platte bestimmt, um welche Pfanne es sich handelt, zum anderen können selbst über die Ausbildung des Thermobildes schon Rückschlüsse über die Beschaffenheit der Feuerfestausmauerung gezogen werden.The currently recorded video image is - as described in Figure 2 - a Evaluation system supplied. Firstly, the number and arrangement the breakthroughs in the plate determines which pan it is for others can even draw conclusions about the formation of the thermal image be drawn on the nature of the refractory lining.
