Description

Die Erfindung betrifft ein Verfahren insbesondere zur Bestimmung des Zustandes einer feuerfesten Auskleidung eines metallurgischen Gefässes, vorzugsweise eines Schmelzgefässes, nach dem Oberbegriff des Anspruches 1.The invention relates to a method, in particular for determining the state of a refractory lining of a metallurgical vessel, preferably a melting vessel, according to the preamble of claim 1.

Es existieren Berechnungsmethoden für die Auslegung der feuerfesten Auskleidung insbesondere von metallurgischen Schmelzgefässen, bei denen ermittelte Daten bzw. Erfahrungswerte in mathematische Modelle überführt werden. Da mit diesen mathematischen Modellen die effektiven Verschleissmechanismen bei den Einsätzen der metallurgischen Gefässen nicht hinreichend genau erfasst bzw. berücksichtigt werden können, sind die Möglichkeiten für ein rechnerisches Bestimmen der Feuerfestzustellungen sowie der Pflegearbeiten der Auskleidung sehr beschränkt, d.h. dass die Entscheidungen über die Einsatzdauer der Feuerfestauskleidung eines Gefässes, zum Beispiel eines Konverters, nach wie vor manuell getroffen werden müssen.There are calculation methods for the design of the refractory lining, in particular of metallurgical melting vessels, at which determined data or empirical values are converted into mathematical models. Since with these mathematical models, the effective wear mechanisms in the inserts of the metallurgical vessels can not be detected or considered with sufficient accuracy, the possibilities for a computational determination of the refractory linings and the care of the lining are very limited, ie that the decisions on the duration of use of the refractory lining a vessel, such as a converter, still needs to be hit manually.

Bei einem Verfahren gemäss der Druckschrift WO-A-03/081157 zum Messen der Reststärke der feuerfesten Auskleidung im Wand-und/oder Bodenbereich eines metallurgischen Gefässes, z. B. eines Lichtbogenofens, werden die ermittelten Messdaten für das nachfolgende Sanieren der festgestellten Verschleissbereiche verwendet. Die Messeinheit wird dabei an einem zum Sanieren der Auskleidung dienenden Manipulator in eine Messposition über oder innerhalb des metallurgischen Gefässes gebracht und es wird dann die Reststärke der Auskleidung in deren Wand- und/oder Bodenbereich gemessen. Aus einem Vergleich mit einem am Anfang der Ofenreise gemessenen Istprofil der Auskleidung wird deren Verschleiss ermittelt, aus denen dann die feuerfeste Auskleidung saniert werden kann. Mit diesem Verfahren ist aber auch keine umfassende Ermittlung der Gefässauskleidung möglich.In a method according to the document WO-A-03/081157 for measuring the residual strength of the refractory lining in the wall and / or bottom area of a metallurgical vessel, for. As an electric arc furnace, the measured data determined for the subsequent renovation of the detected wear areas are used. The measuring unit is brought to a serving for refurbishing the lining manipulator in a measuring position above or within the metallurgical vessel and it is then measured the residual thickness of the lining in the wall and / or floor area. From a comparison with a measured at the beginning of the furnace travel actual profile of the lining whose wear is determined, from which then the refractory lining can be rehabilitated. With this method, however, no comprehensive determination of the vessel lining is possible.

Gemäss der Druckschrift WO-A-2007/107242 ist ein Verfahren zur Bestimmung der Wandstärke oder des Verschleisses der Auskleidung eines metallurgischen Schmelzgefässes mit einem Scannersystem zur berührungslosen Erfassung der Auskleidungsfläche mit Ermittlung der Position und Orientierung des Scannersystems und Zuordnung zu der Position des Schmelzgefässes durch die Erfassung von raumfesten Referenzpunkten geoffenbart. Es wird dabei ein lotrechtes Bezugssystem verwendet und die Neigungen von zwei Achsen bezüglich einer waagrechten Ebene werden mittels Neigungssensoren gemessen. Die Messdaten des Scanners können in ein lotrechtes Koordinatensystem transformiert und es ist damit ein automatisiertes Messen des jeweiligen Istzustandes der Auskleidung des Schmelzgefässes möglich.According to the document WO 2007/107242 is a method for determining the wall thickness or wear of the lining of a metallurgical melting vessel with a scanner system for contactless detection of the lining surface with determination of the position and orientation of the scanner system and assignment to the position of the melting vessel revealed by the detection of fixed spatial reference points. In this case, a perpendicular reference system is used and the inclinations of two axes with respect to a horizontal plane are measured by inclination sensors. The measurement data of the scanner can be transformed into a perpendicular coordinate system and thus an automated measurement of the respective actual state of the lining of the melting vessel is possible.

Ausgehend von diesen bekannten Berechnungsmethoden bzw. Messverfahren liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren zu schaffen, mittels welchem die Haltbarkeit der feuerfesten Auskleidung eines metallurgischen Gefässes und der Prozess an sich optimiert werden kann und manuelle Entscheidungen dafür reduziert bzw. praktisch eliminiert werden.Based on these known calculation methods or measuring methods, the present invention has the object to provide a method by means of which the durability of the refractory lining of a metallurgical vessel and the process itself can be optimized and manual decisions are reduced or virtually eliminated.

Erfindungsgemäss ist diese Aufgabe nach den Merkmalen des Anspruchs 1 gelöst.According to the invention this object is achieved according to the features of claim 1.

Das Verfahren nach der Erfindung sieht vor, dass Daten eines jeweiligen Gefässes umfassend gesammelt und in einer Datenstruktur gespeichert werden, und aus all den gemessenen und ermittelten Daten bzw. Parametern ein Rechenmodell erstellt wird, mittels dem diese Daten bzw. Parameter durch Berechnungen und daraus folgenden Analysen ausgewertet werden.The method according to the invention provides that data of a respective vessel are comprehensively collected and stored in a data structure, and from all the measured and determined data or parameters a calculation model is created by means of which these data or parameters are determined by calculations and subsequent calculations Analyzes are evaluated.

Mit diesem erfindungsgemässen Verfahren können bei einem metallurgischen Gefäss nicht nur Messungen für die Feststellung des Istzustandes des Gefässes nach dessen Gebrauch ermittelt werden, sondern es können zusammenhängende bzw. ganzheitliche Ermittlungen und daraus Analysen erfolgen, aus denen Optimierungen sowohl in Bezug auf die Gefässauskleidung als auch auf den gesamten Prozessablauf der in das Gefäss eingefüllten und darin behandelten Schmelze erzielt werden.With this method according to the invention, not only measurements for the determination of the actual state can be made in a metallurgical vessel of the vessel after its use, but it is possible to carry out coherent investigations and analyzes therefrom, from which optimization is achieved both with regard to the vessel lining and to the entire process flow of the melt introduced into the vessel and treated therein.

Weitere vorteilhafte Einzelheiten dieses Verfahrens im Rahmen der Erfindung sind in den abhängigen Ansprüchen definiert.Further advantageous details of this method in the context of the invention are defined in the dependent claims.

Ausführungsbeispiele sowie weitere Vorteile der Erfindung sind nachfolgend anhand einer Zeichnung näher erläutert. Es zeigt:

Embodiments and other advantages of the invention are explained below with reference to a drawing. It shows:
Fig. 1
a schematic longitudinal section of a sectored metallurgical vessel.

Das Verfahren bezieht sich insbesondere auf metallurgische Gefässe, wie ein solches Gefäss 10 als Ausführungsbeispiel in Fig. 1 geschnitten dargestellt ist. Bei dem Gefäss 10 handelt es sich vorliegend um einen an sich bekannten Konverter bei der Stahlerzeugung. Das Gefäss 10 besteht im Wesentlichen aus einem Metallgehäuse 15, einer feuerfesten Auskleidung 12 und Gasspülsteinen 17, 18, welche mit einer nicht näher gezeigten Gasversorgung koppelbar sind.The method relates in particular to metallurgical vessels, such as such a vessel 10 as an embodiment in Fig. 1 is shown cut. The vessel 10 in the present case is a known converter in steelmaking. The vessel 10 consists essentially of a metal housing 15, a refractory lining 12 and gas purging 17, 18, which can be coupled with a gas supply not shown in detail.

Die im Betrieb in dieses Gefäss 10 eingefüllte Metallschmelze wird beispielsweise durch ein Blasverfahren metallurgisch behandelt, was nicht näher erläutert ist. Üblicherweise sind in einem Stahlwerk gleichzeitig mehrere solcher Konverter im Einsatz und es sind für jeden dieser Konverter die Daten zu erfassen.The filled during operation in this vessel 10 molten metal is treated metallurgically, for example, by a blown, which is not explained in detail. Usually, several such converters are in use in a steelworks at the same time and it is necessary to record the data for each of these converters.

Das Verfahren kann selbstverständlich für verschiedene metallurgische Gefässe angewendet werden, wie zum Beispiel für Elektroofen, Hochofen, Stahlpfannen, Gefässe im Bereich von Nichteisenmetallen, wie Aluminium-Schmelzofen, Kupfer-Anodenofen oder dergleichen.The method can of course be applied to various metallurgical vessels, such as electric furnace, blast furnace, steel ladle, non-ferrous metal vessel such as aluminum smelting furnace, copper anode furnace or the like.

Das Verfahren zeichnet sich noch dadurch aus, dass es gleichsam für verschiedene Behälter angewendet werden kann. So können beispielsweise die feuerfesten Auskleidungen aller im Betrieb stehenden Konverter und Pfannen bestimmt werden, bei denen die gleiche Schmelze zuerst in einem Konverter behandelt und nachfolgend in Stahlpfannen umgegossen werden.The method is characterized by the fact that it can be applied for different containers. For example, the refractory linings of all converters and pans in operation can be determined, in which the same melt is first treated in a converter and subsequently poured into steel pans.

Es werden als Erstes die in Gruppen unterteilten Daten eines jeweiligen Gefässes 10 umfassend gesammelt und in einer Datenstruktur gespeichert.First, the data divided into groups of a respective vessel 10 are comprehensively collected and stored in a data structure.

Um den Verschleiss als eine Gruppe der innerhalb des Metallgehäuses 15 eingebetteten Gefässauskleidung 12 zu messen, erfolgt dies vorerst bei der in der Regel mit unterschiedlichen Steinen 14, 16 bzw. Wandstärken versehenen neuen Feuerfestzustellung. Dies kann eben durch Messen oder durch das Bekanntsein der vorgegebenen Abmessungen der Steine 14, 16 erfolgen. Zudem werden die Materialien und Materialeigenschaften der verwendeten Steine 14, 16 und der allfällig verwendeten Einspritzmaterialien erfasst.In order to measure the wear as a group of embedded within the metal housing 15 vessel liner 12, this is done initially in the usually provided with different stones 14, 16 and wall thicknesses new Feuerfestbestellung. This can be done just by measuring or by the knownness of the given dimensions of the stones 14, 16. In addition, the materials and material properties of the stones used 14, 16 and the possibly used injection materials are detected.

Vorteilhaft werden eine reduzierte Anzahl aus den gemessenen bzw. ermittelten Daten bzw. Parametern für die wiederkehrenden Berechnungen bzw. Analysen ausgewählt, wobei dies in Abhängigkeit von Erfahrungswerten oder durch Rechenmethoden erfolgt. Diese Auswahl der gemessenen bzw. ermittelten Daten bzw. Parametern für die wiederkehrenden Berechnungen bzw. Analysen erfolgt mittels Algorithmen, beispielsweise einer Random Feature Selection.Advantageously, a reduced number is selected from the measured or determined data or parameters for the recurrent calculations or analyzes, this taking place as a function of empirical values or by calculation methods.
