Im Rahmen der Verarbeitung von Bandmaterial aus einem Eisenwerkstoff oder einem Nichteisenmetall ist es häufig üblich, beispielsweise vor Durchführung eines oder mehrerer Walzschritte(s), eine Erwärmung des Bandmaterials vorzunehmen, damit dieses im anschließenden Tiefziehprozess gut zu verarbeiten ist. Beispielsweise werden bei einer Glühbehandlung Metallbänder einem Glühofen zugeführt und dort einer Temperatur von 700 - 900°C ausgesetzt, um damit vorher beispielsweise kaltgewalzten Bänder soweit aufzubereiten, dass sie in dem nachfolgenden Tiefziehprozess und gegebenenfalls einem Beschichtungsprozess gut verarbeitbar sind.In the context of the processing of strip material from a ferrous material or a non-ferrous metal, it is often customary, for example, before carrying out one or more rolling steps (s) to carry out a heating of the strip material, so that it is easy to process in the subsequent deep-drawing process. For example, in an annealing treatment, metal strips are fed to an annealing furnace and exposed there to a temperature of 700-900 ° C. in order to prepare, for example, cold-rolled strips so far that they can be readily processed in the subsequent deep-drawing process and optionally a coating process.

In order to achieve this, automated process control is an indispensable prerequisite.

Here it is already provided to control the local annealing furnace with the aid of a measuring device which detects a mechanical material properties of the strip material reproducing and / or imaging measurement. However, it is provided that the furnace parameters are controlled directly.

Nachteilig bei diesem Stand der Technik ist es, dass der Glühofen thermisch träge ist und sich die Bedingungen im Ofen nicht schnell ändern. Deswegen versagt ein Standardregelkonzept.A disadvantage of this prior art is that the annealing furnace is thermally inert and the conditions in the furnace do not change rapidly. That's why a standard rule concept fails.

Diese Regelungs- und/oder Steuerungseinheit lernt anhand des vergangenen Verhaltens des Ofens die Reaktion des Ofens bei veränderten Bedingungen des Ofens und verstellt diese um die Messwerte für kommende Bänder einzustellen. Dadurch wird die Streuung der Messwerte geringer. Für diesen Lernprozess können auch Informationen zu Prozessen vor dem Glühofen genutzt werden (seien es Messwerte oder Stellwerte).This control and / or control unit learns on the basis of the past behavior of the furnace, the reaction of the furnace under changed conditions of the furnace and adjusts them to adjust the readings for upcoming bands. This reduces the dispersion of the measured values. Information about processes in front of the annealing furnace can be used for this learning process (be it measured values or set values).

Bei dem datenübertragenden Signal kann es sich um ein elektrisches Signal, ein elektronisches Signal, ein Signal in Form einer elektromagnetischen Welle, ein Funksignal, ein Lichtsignal oder Infrarotsignal handeln, welches geeignet ist, Messwerte oder Informationen zu übertragen.The data-transmitting signal may be an electrical signal, an electronic signal, a signal in the form of an electromagnetic wave, a radio signal, a light signal or infrared signal, which is suitable for transmitting measured values or information.

Durch die Erfindung wird erreicht, dass die gesamte Länge eines wärmebehandelten oder geglühten Bandmaterials am Ofenausgang oder in Bandbearbeitungsrichtung hinter dem Glüh- oder Wärmebehandlungsofen erfasst wird. Durch diese vorzugsweise kontinuierlich durchgeführte Überwachung der mechanischen Eigenschaften des geglühten oder wärmebehandelten Bandmaterials kann die Einstellung des Ofens derart erfolgen, dass für folgende Bänder die mechanischen Eigenschaften in dem gewünschten Wertefenster liegen, d.h. lediglich eine tolerierte Streubreite oder Streuung aufweisen. Da die mechanischen Eigenschaften dauerhaft und kontinuierlich während der Durchführung eines Prozesse überwacht werden, können die tatsächlichen Grenzwerte der mechanischen Eigenschaften auch als Grenzwerte des Steuerungs- und/oder Messsystems benutzt werden. Das Prozessfenster ist derjenige Bereich (von einem Minimalwert bis zu einem Maximalwert) für einen Ofenparameter (Ofenzonentemperatur, Bandzieltemperatur oder Bandgeschwindigkeit), dessen Einhaltung im Produktionsverfahren zur Produktion der geforderten mechanischen Eigenschaften des Bandes führt. Die Glühzyklen können angepasst werden und die Prozessfenster verändert werden. Im besten Fall ist es nicht mehr notwendig, sich auf vorher definierte Parameter wie einen Glühzyklus und damit zusammenhängende Grenzwerte zu beschränken. Die Streuung der mechanischen Eigenschaften über den gesamten Glühprozess ist damit optimiert und besser an die gewünschten Parameter und Randbedingungen angepasst. Dies ermöglicht es zudem, eher an die Grenzen z.B. der zur Erreichung der gewünschten mechanischen Eigenschaften notwendigen oder angepassten Glühtemperatur zu gehen und damit den Prozess ökologischer oder ökonomischer zu gestalten, insbesondere dessen Produktivität erhöhen zu können. Außerdem ist es durch die erfindungsgemäße Art der Messung möglich, Übergänge zwischen Bandmaterial von unterschiedlicher Güte besser durchzuführen und aufeinander abzustimmen, da die jeweils ausgewählte mechanische Eigenschaft des jeweiligen Bandmaterials als relevanter Größe voreingestellt werden und damit die Überlappung der nacheinander folgenden Bänder gesteuert werden kann.By the invention it is achieved that the entire length of a heat treated or annealed strip material is detected at the furnace exit or in the strip processing direction behind the annealing or heat treatment furnace. As a result of this preferably continuous monitoring of the mechanical properties of the annealed or heat-treated strip material, the setting of the furnace can be such that the following properties have the mechanical properties in the desired value window, ie only a tolerated spread or Have scattering. Since the mechanical properties are permanently and continuously monitored during the performance of a process, the actual limits of the mechanical properties can also be used as limits of the control and / or measuring system. The process window is that range (from a minimum value to a maximum value) for an oven parameter (oven zone temperature, belt target temperature or belt speed), compliance with which in the production process results in the production of the required mechanical properties of the belt. The annealing cycles can be adjusted and the process windows changed. In the best case, it is no longer necessary to limit to previously defined parameters such as an annealing cycle and related limits. The dispersion of the mechanical properties over the entire annealing process is thus optimized and better adapted to the desired parameters and boundary conditions. This makes it possible, moreover, to go to the limits of, for example, the annealing temperature necessary or adapted to achieve the desired mechanical properties and thus to make the process more ecological or economical, in particular to be able to increase its productivity. In addition, it is possible by the inventive type of measurement to better perform transitions between band material of different quality and to match, since the selected mechanical property of the respective strip material are preset as the relevant size and thus the overlap of the successive bands can be controlled.

Die erfindungsgemäße Vorrichtung umfasst ein dem Glüh-oder Wärmebehandlungsofen nachgeschaltetes Walz- oder Streckgerüst, welches in dem Regelungs- und/oder Steuerungskreislauf der automatischen Prozesssteuerung mit dem Glüh- oder Wärmebehandlungsofen und dem mindestens einen Messgerät zusammenwirkt.The device according to the invention comprises a rolling or stretching stand downstream of the annealing or heat treatment furnace, which cooperates in the control and / or control circuit of the automatic process control with the annealing or heat treatment furnace and the at least one measuring device.

Hierbei kann es weiterhin so sein, dass ein Messgerät in Bandbearbeitungsrichtung hinter dem Streckgerüst angeordnet ist, was die Erfindung ebenfalls vorsieht.In this case, it can continue to be the case that a measuring device is arranged in the strip processing direction behind the stretching stand, which the invention also provides.

Ein erstes Messgerät kann in Bandmaterialbearbeitungsrichtung unmittelbar hinter dem Glüh- oder Wärmebehandlungsofen und vor einem oder dem Walz- und/oder Streckgerüst angeordnet sein. Durch die Anordnung eines Messgerätes hinter dem Glüh- oder Wärmeofen, aber vor einem nachfolgenden Walz- und/oder Streckgerüst wird es ermöglicht, den Einfluss der Glüh- oder Wärmebehandlung auf die gemessene mechanische Eigenschaft des Bandmaterials zur Grundlage der Regelung oder Steuerung des Ofenbetriebes zu machen.A first measuring device may be arranged in the strip material processing direction directly behind the annealing or heat treatment furnace and in front of one or the rolling and / or stretching stand. The arrangement of a measuring device behind the annealing or heating furnace, but before a subsequent rolling and / or stretching stand, it is possible to make the influence of the annealing or heat treatment on the measured mechanical property of the strip material to the basis of the control or control of the furnace operation ,

In Weiterbildung der Erfindung ist darüber hinaus vorgesehen, dass das erste Messgerät in Bandmaterialbearbeitungsrichtung hinter dem Glüh- oder Wärmebehandlungsofen und vor dem Walz- und/oder Streckgerüst angeordnet ist sowie ein zweites Messgerät hinter dem Streckgerüst angeordnet ist.In a further development of the invention it is further provided that the first measuring device is arranged in the strip material processing direction behind the annealing or heat treatment furnace and before the rolling and / or stretching stand and a second measuring device is arranged behind the stretching stand.

Dadurch, dass das zweite Messgerät in Bandmaterialbearbeitungsrichtung hinter dem Streckgerüst angeordnet ist, ist es möglich, auch die Beeinflussung durch die mechanischen Bearbeitungsstationen, welche ein oder mehrere Walzgerüst(e), ein oder mehrere Streckgerüst(e), Dressiergerüst(e) oder Streckrichter umfassen können, auf die jeweils gemessene mechanische Eigenschaft zu ermitteln und bei der Steuerung sowohl des Glüh- oder Wärmebehandlungsofens als auch bei der Steuerung der mechanischen Bearbeitungsstationen oder -einrichtungen, d.h. den Walz- und/oder Streckgerüst(en), zu berücksichtigen. Von Vorteil ist die Messung mit einem in Bearbeitungsrichtung des Bandmaterials hinter einem Streckgerüst angeordneten Messgerät insofern, als dass dann die mechanische Eigenschaft des Bandes nach einem Verformungsprozess berücksichtigt werden kann. Insbesondere ist es in diesem Zusammenhang von Vorteil, die mechanischen Eigenschaften des Endproduktes für die Steuerung in den Regelungs- und/oder Steuerungskreislauf einfließen zu lassen, weshalb eben auch vorgesehen sein kann, dass ein Messgerät in Bearbeitungsrichtung hinter der letzten mechanischen Bearbeitungsvorrichtung der Fertigungsstraße angeordnet ist.Because the second measuring device is arranged downstream of the stretching stand in the strip material processing direction, it is also possible to influence the mechanical processing stations which comprise one or more rolling stand (s), one or more stretching stand (s), skin pass mill (s) or stretch leveling jig For example, it is possible to determine the mechanical properties measured in each case and to take them into account in the control of both the annealing or heat treatment furnace and in the control of the mechanical processing stations or devices, ie the rolling and / or stretching stand (s). It is advantageous to measure with a measuring device arranged behind a stretching stand in the machining direction of the strip material in that then the mechanical property of the strip after a deformation process can be taken into account. In particular, it is advantageous in this context to incorporate the mechanical properties of the end product for the control in the control and / or control circuit, which is why it can also be provided that a measuring device is arranged in the processing direction behind the last mechanical processing device of the production line ,

Allerdings ist es auch möglich, beide Messgeräte jeweils auf Mess- und Regelkreise des Regelungs- und/oder Steuerungskreislaufs einwirken zu lassen, die auf die Ofensteuerung und die mechanische Bearbeitung und die damit jeweils in Verbindung stehenden Einrichtungen und Vorrichtungen einwirken.However, it is also possible to have both measuring devices in each case act on measuring and control circuits of the control and / or control circuit, which act on the furnace control and the mechanical processing and the related devices and devices.

Bei dem Einsatz von zwei Messgeräten kann aber auch vorgesehen sein, dass ein erstes Messgerät in Bandmaterialbearbeitungsrichtung unmittelbar hinter dem Glüh-oder Wärmebehandlungsofen und ein weiteres Messgerät in Bandmaterialbearbeitungsrichtung vor dem Glüh- oder Wärmebehandlungsofen angeordnet ist oder, dass das weitere Messgerät in Bandmaterialbearbeitungsrichtung vor dem Glüh-oder Wärmebehandlungsofen und ein zweites Messgerät in Bandmaterialbearbeitungsrichtung hinter dem Streckgerüst angeordnet ist. Die jeweiligen Messwerte gehen zu einer Steuerungs-/Regelungseinheit, die per Lernfunktion auf die Ofensteuerung und je nach Fall auf die mechanische Bearbeitung einwirkt. Hierzu sieht die Erfindung vor, dass ein erstes Messgerät in Bandmaterialbearbeitungsrichtung unmittelbar hinter dem Glüh- oder Wärmebehandlungsofen angeordnet ist sowie ein weiteres Messgerät in Bandmaterialbearbeitungsrichtung vor dem Glüh- oder Wärmebehandlungsofen angeordnet ist. Ebenso zeichnet sich die Erfindung im Hinblick auf diesen Aspekt dadurch aus, dass ein zweites Messgerät in Bandmaterialbearbeitungsrichtung hinter dem Streckgerüst und das weitere Messgerät in Bandmaterialbearbeitungsrichtung vor dem Glüh- oder Wärmebehandlungsofen angeordnet ist.When two measuring devices are used, however, provision can also be made for a first measuring device to be arranged in the strip material processing direction directly behind the annealing or heat treatment furnace and another measuring device in the strip material processing direction in front of the annealing or heat treatment furnace, or for the further measuring device to be in the strip material processing direction before annealing or heat treatment furnace and a second measuring device in strip material processing direction behind the stretching stand is arranged. The respective measured values go to a control / regulation unit, which acts on the furnace control via a learning function and, depending on the case, on the mechanical processing. For this purpose, the invention provides that a first measuring device in the strip material processing direction is arranged directly behind the annealing or heat treatment furnace and another measuring device is arranged in the strip material processing direction before the annealing or heat treatment furnace. Likewise, with regard to this aspect, the invention is characterized in that a second measuring device in strip material processing direction is arranged behind the stretching stand and the further measuring device in strip material processing direction in front of the annealing or heat treatment furnace.

In zweckmäßiger Ausgestaltung zeichnet sich die Erfindung zudem dadurch aus, dass Das in Bandmaterialbearbeitungsrichtung hinter dem Glüh- oder Wärmebehandlungsofen angeordnete erste Messgerät und/oder das in Bandmaterialbearbeitungsrichtung vor dem Glüh- oder Wärmebehandlungsofen angeordnete weitere Messgerät wirken in Rückkopplung auf die Ofensteuerung ein.In an advantageous embodiment, the invention is also characterized by the fact that arranged in Bandmaterialbearbeitungsrichtung behind the annealing or heat treatment furnace first meter and / or arranged in Bandmaterialbearbeitungsrichtung before the annealing or heat treatment furnace further measuring device act in feedback to the furnace control.

Hierbei sieht die Erfindung zu dem weiterhin vor, dass das in Bandmaterialbearbeitungsrichtung hinter dem Streckgerüst oder hinter einem Streckgerüst angeordnete zweite Messgerät und das erste oder das weitere Messgerät, welche in Bandmaterialbearbeitungsrichtung vor oder unmittelbar hinter dem Glüh- oder Wärmebehandlungsofen angeordnet sind, in Rückkopplung auf die Ofensteuerung und die Steuerung des Streckgerüsts einwirken.In this case, the invention furthermore provides for the second measuring device arranged in the band material processing direction behind the stretching stand or behind a stretching stand, and the first or the further measuring device, which in the strip material processing direction before or immediately after the annealing or heat treatment furnace are arranged to act in feedback on the furnace control and the control of the stretching stand.

Von Vorteil ist es weiterhin, wenn das zweite Messgerät, falls vorhanden, in Bandmaterialbearbeitungsrichtung hinter der letzten mechanischen Bearbeitungsvorrichtung der Fertigungsstraße angeordnet ist, was die Erfindung in Ausgestaltung ebenfalls vorsieht. Hierbei wird dann der Einfluss der gesamten vorhergehenden Materialbearbeitung oder Materialbehandlung in der Fertigungsstraße auf die gemessene mechanische Eigenschaft des Bandmaterials zur Grundlage der Regelung oder Steuerung des Ofenbetriebes und/oder der mechanischen Bearbeitung gemacht. Eine besonders zweckmäßige Messung ist die Realzeit-Onlinemessung. Daher zeichnet sich die Erfindung in Ausgestaltung weiterhin dadurch aus, dass die Messgeräte den mechanische Werkstoffeigenschaften des Bandmaterials abbildenden Messwert mittels einer Realzeit-Onlinemessung erfassen.It is also advantageous if the second measuring device, if present, is arranged in the strip material processing direction behind the last mechanical processing device of the production line, which the invention also provides in an embodiment. In this case, the influence of the entire preceding material processing or material treatment in the production line on the measured mechanical property of the strip material is used as the basis for controlling or controlling the furnace operation and / or the mechanical processing. A particularly useful measurement is the real-time online measurement. Therefore, the invention in an embodiment is further distinguished by the fact that the measuring devices detect the measured value representing the mechanical material properties of the strip material by means of a real-time online measurement.

Besonders günstig und zweckmäßig lässt sich ein Glüh- oder Wärmebehandlungsofen erfindungsgemäß steuern und/oder regeln, wenn der Regelungs- und/oder Steuerungskreislauf eine darin abgebildete und/oder abgelegte Ofenmodellsteuerung umfasst, was die Erfindung ebenfalls vorsieht. Hierbei kann die Ofenmodellsteuerung jede Art von Modell umfassen, ausgehend von einem einfachen linearen Modell bis zu einem thermodynamischen Modell mit Lern- und Adaptionsfunktion kann jede Art von Ofenmodell Verwendung zur Ablage als Ofenmodellsteuerung finden.According to the invention, an annealing or heat treatment furnace can be controlled and / or regulated in a particularly favorable and expedient manner if the control and / or control circuit comprises an oven model control shown therein and / or stored, which the invention also provides. Here, the furnace model controller may include any type of model, from a simple linear model to a thermodynamic model with learning and adaptation function, any type of furnace model may find use as a furnace model controller for deposition.

Zudem kann in weiterer Ausgestaltung der Erfindung auch vorgesehen sein, dass der Regelungs- und/oder Steuerungskreislauf ein Werkstoffmodell umfasst.In addition, in a further embodiment of the invention can also be provided that the control and / or control circuit comprises a material model.

Zweckmäßige Ofenparameter, die mit einem erfindungsgemäß ausgestalteten Regelungs- und/oder Steuerungssystem gesteuert werden können, sind beispielsweise die Bandzieltemperatur im Heiz- und/oder Kühlbereich des Glüh- und/oder Wärmebehandlungsofens, die Bandgeschwindigkeit in der Prozesslinie, die Ofentemperatur oder die Ofenleistung des Glüh- und/oder Wärmebehandlungsofens, die Kühlmittelbeaufschlagung des bearbeiteten Bandmaterials oder die Kühlmittelart. Die Erfindung zeichnet sich daher weiterhin dadurch aus, dass sie Ofenparameter steuert, die mindestens einen der Werte Bandzieltemperatur im Heiz- und/oder Kühlbereich des Glüh- oder Wärmebehandlungsofens, Prozessfenster dieser Bandzieltemperatur, Bandgeschwindigkeit, Prozessfenster dieser Bandgeschwindigkeit, Ofentemperatur, Prozessfenster dieser Ofentemperatur, Ofentemperaturmuster (örtliche und zeitliche Ofentemperaturverteilung), Ofenleistung, Kühlrate, Kühlmittelbeaufschlagung oder Kühlmittelart umfassen.Useful furnace parameters which can be controlled with a control and / or control system designed according to the invention are, for example, the strip target temperature in the heating and / or cooling region of the annealing and / or heat treatment furnace, the belt speed in the process line, the furnace temperature or the furnace output of the glow and / or heat treatment furnace, the coolant loading of the processed strip material or the type of coolant. The invention is therefore further distinguished by the fact that it controls furnace parameters which comprise at least one of the values band target temperature in the heating and / or cooling region of the annealing or heat treatment furnace, process window of this band target temperature, belt speed, process window of this belt speed, furnace temperature, process window of this furnace temperature, furnace temperature pattern (local and temporal furnace temperature distribution), furnace output, cooling rate, coolant loading or coolant type.

Ein besonders geeignetes Messgerät ist ein Remanenzmessgerät, weshalb die Erfindung weiterhin vorsieht, dass die Messgeräte jeweils ein Remanenzmessgerät sind, das als Messwert eine magnetische Größe detektiert.A particularly suitable measuring device is a remanence meter, which is why the invention further provides that the measuring devices are each a remanence meter which detects a magnetic quantity as the measured value.

Das eine mechanische Eigenschaft detektierende Messgerät kann aber auch als Laser-Ultraschallgerät oder elektromagnetisches Ultraschallgerät oder Röntgentransmissionsgerät ausgebildet sein.However, the measuring device which detects a mechanical property can also be designed as a laser ultrasound device or an electromagnetic ultrasound device or an X-ray transmission device.

Von besonderem Vorteil sind die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren beim Glühen oder Verzinken von Stahl oder Aluminiummaterial zu verwenden. Die Erfindung zeichnet sich daher auch dadurch aus, dass die Vorrichtung Bestandteil einer kontinuierlichen Glüh- und/oder Verzinkungslinie für ein Stahl- oder Aluminiummaterial ist.The device according to the invention and the method according to the invention are of particular advantage in the annealing or galvanizing of steel or aluminum material. The invention is therefore also characterized in that the device is part of a continuous annealing and / or galvanizing line for a steel or aluminum material.

In gleicher Weise wie die erfindungsgemäße Vorrichtung umfasst das erfindungsgemäße Verfahren ein in Bandmaterialbearbeitungsrichtung unmittelbar hinter dem Glüh- oder Wärmebehandlungsofen angeordnetes erstes Messgerät und ein hinter dem Walz- und/oder Streckgerüst angeordnetes zweites Messgerät mittels welcher mechanische Werkstoffeigenschaften des Bandmaterials abbildende Messwerte ermittelt werden, die in Rückkopplung auf die Ofensteuerung oder Ofenregelung des Glüh- oder Wärmebehandlungsofens und die Regelung und/oder Steuerung des Walzgerüsts und des Streckgerüsts auf den Regelungs- und/oder Steuerungskreislauf der automatisierten Prozesssteuerung einwirken.In the same way as the device according to the invention, the method according to the invention comprises a first measuring device arranged in the strip material processing direction directly behind the annealing or heat treatment furnace and a second measuring device arranged behind the rolling and / or stretching stand by means of which measured values representing mechanical material properties of the strip material are determined Feedback on the furnace control or furnace control of the annealing or heat treatment furnace and the regulation and / or control of the rolling stand and the stretching stand on the control and / or control circuit of the automated process control act.

Von Vorteil ist es hierbei, wenn mittels des in Bandmaterialbearbeitungsrichtung hinter dem Glüh- oder Wärmebehandlungsofen und vor dem oder einem Walz- und/oder Streckgerüst angeordneten ersten Messgerätes und des in Bandmaterialbearbeitungsrichtung hinter dem Walz- und/oder Streckgerüst angeordneten zweiten Messgerätes oder mittels des in Bandmaterialbearbeitungsrichtung vor dem Glüh-oder Wärmebehandlungsofen angeordneten weiteren Messgerätes online jeweils der mechanische Werkstoffeigenschaften des Bandmaterials abbildende Messwert erfasst und an die Regelungs- und/oder Steuerungseinheit übermittelt wird.It is advantageous in this case if, by means arranged in the strip material processing direction behind the annealing or heat treatment furnace and before or a rolling and / or stretching stand first measuring device and arranged in Bandmaterialbearbeitungsrichtung behind the rolling and / or stretching stand second measuring device or by means of in Bandmaterialbearbeitungsrichtung before the annealing or heat treatment furnace arranged further measuring device online each of the mechanical material properties of the strip material imaging measured value recorded and transmitted to the control and / or control unit.

Ebenso werden mittels des in Bandmaterialbearbeitungsrichtung hinter dem oder einem Walz- und/oder Streckgerüst angeordneten zweiten Messgerätes und des in Bandmaterialbearbeitungsrichtung vor oder unmittelbar hinter dem Glüh- oder Wärmebehandlungsofen angeordneten zweiten oder weiteren Messgerätes online mechanische Werkstoffeigenschaften des Bandmaterials wiedergebende und/oder abbildende Messwerte erfasst und an die Regelungs- und/oder Steuerungseinheit übermittelt.Likewise, on-line mechanical material properties of the strip material reproducing and / or reproducing measured values are recorded by means of the second measuring device arranged behind the or a rolling and / or stretching stand in strip material processing direction and the second or further measuring device arranged in front or behind the annealing or heat treatment furnace transmitted to the control and / or control unit.

Hierbei ist es dann ebenfalls zweckmäßig, dass der mechanische Werkstoffeigenschaften des Bandmaterials abbildende Messwert mittels einer Realzeit-Onlinemessung erfasst wird, was die Erfindung in Weiterbildung ebenfalls vorsieht.In this case, it is also expedient that the measured value that reflects the mechanical material properties of the strip material is recorded by means of a real-time online measurement, which the invention also provides in a further development.

Schließlich zeichnet sich die erfindungsgemäße Vorrichtung dadurch aus, dass das Verfahren mit einer Vorrichtung nach einem oder mehreren Ansprüche 1 - 8 durchgeführt wird.Finally, the device according to the invention is characterized in that the method is carried out with a device according to one or more of claims 1-8.
