Description
Einrichtung zum Regeln der Planheit Device for regulating the flatness
von bandfermigem Walzgut für Kaltwalzwerke Die Erfindung bezieht sich auf eine Einrichtung zum Regeln der Planheit von bandförmigem Walzgut, insbesondere von Feinbändern, für Kaltwalzwerke mit einem hinter dem Walzspalt angeordneten berührungslos arbeitenden Temperaturmeßgerät zur Messung der Temperatur über die Bandbreite des kontinuierlich laufenden Bandes, wobei die ermittelten Meßwerte zur Impulserzeugung für die Regelung der Walzenbiegeeinrichtung und/ oder der Walzenkühleinrichtung verwendet sind, nach Patent ..... of strip-shaped rolling stock for cold rolling mills The invention relates on a device for regulating the flatness of strip-shaped rolling stock, in particular of fine strip, for cold rolling mills with a contactless one arranged behind the roll gap working temperature measuring device for measuring the temperature over the bandwidth of the continuously running belt, with the determined measured values for pulse generation for controlling the roll bending device and / or the roll cooling device are used, according to patent .....
(Patentanmeldung P 23 49 611.9-14).(Patent application P 23 49 611.9-14).
Die Regeleinrichtung nach dem Hauptpatent ..... (Patentanmeldung P 23 49 611.9-14) arbeitet ungenau, da die gemessenen Temperaturwerte durch äußere Störeinflüsse, die beispielsweise durch das auf dem aus dem Walzwerk austretenden Walzband befindliche Walzöl sowie Öldämpfe bedingt sind, verfälscht werden. The control device according to the main patent ..... (patent application P 23 49 611.9-14) works imprecisely because the measured temperature values are due to external Interferences caused, for example, by the emerging from the rolling mill Rolling oil and oil vapors contained in the rolled strip are falsified.
Die Erfindung hat sich zum Ziel gesetzt, eine Einrichtung zum Regeln der Planheit von bandförmigem Walzgut, insbesondere Feinbändern,für Kaltwalzwerke zu schaffen, die unabhängig vcn äußeren Störeinflüssen arbeitet. The invention has set itself the goal of a device for regulating the flatness of strip-shaped rolled material, especially fine strips, for cold rolling mills to create that works independently of external interference.
Ausgehend von einer Regeleinrichtung der eingangs beschriebenen Art wird diese Aufgabe dadurch gelöst, daß das Temperaturmeßgerät als Strahlungs-Abtasteinrichtung mit verschiedenen Spektralbereichen ausgebildet ist. Based on a control device of the type described above This object is achieved in that the temperature measuring device is used as a radiation scanning device with different Spectral ranges is formed.
Einem weiteren Merkmal der Erfindung zufolge weist die Strahlungs-Abtasteinrichtung einen Ultrarot-Meßbereich auf. According to a further feature of the invention, the radiation scanning device an ultra-red measuring range.
Die Verwendung einer Strahlungs-Abtasteinrichtung mit verschiedenen Spektralbereichen bei der erfindungsgemäßen Regeleinrichtung ermöglicht es, den Störeinfluß von Strahlungsquellen außerhalb der Objektgrenzen auszuschalten. Dies wird durch den Einbau von entsprechenden Filtern in den Strahlengang des Abtastgerätes erreicht. Die Abtasteinrichtung kann außerhalb des Hauptarbeitsbereiches des Walzwerkes angeordnet werden, so daß Beschädigungen der Einrichtung ausgeschlossen sind. The use of a radiation scanner with various Spectral ranges in the control device according to the invention enables the Eliminate interference from radiation sources outside the object boundaries. this is achieved by installing appropriate filters in the beam path of the scanning device achieved. The scanning device can be outside the main working area of the rolling mill be arranged so that damage to the device is excluded.
Weitere Einzelheiten der Erfindung sind der nachfolgenden Beschreibung eines in der Zeichnung dargestellten Ausführungsbeispiels zu entnehmen. Es zeigen Fig. 1 eine Regeleinrichtung mit einem hinter dem Walzspalt angeordneten Bandtemperaturmeßgerät in schematischer Darstellung und Fig. 2 eine perspektivische schematische Darstellung des als Strahlungs-Abtasteinrichtung ausgebildeten Temperaturmeßgerätes. Further details of the invention are the following description an embodiment shown in the drawing. Show it 1 shows a control device with a strip temperature measuring device arranged behind the roll gap in a schematic illustration and FIG. 2 is a perspective schematic illustration of the temperature measuring device designed as a radiation scanning device.
Das Walzgerüst nach Fig. 1 weist in bekannter Weise zwei Stützwalzen 1, 2 sowie zwei Arbeitswalzen 3, 4 auf, zwischen denen das Band 5 in Pfeilrichtung a durch den Walzspalt 6 läuft. The roll stand according to FIG. 1 has, in a known manner, two backup rolls 1, 2 and two work rolls 3, 4, between which the belt 5 in the direction of the arrow a runs through the roll gap 6.
Die Durchbiegung der Arbeitswalzen 3, 4 wird durch eine Stellvorrichtung 7, 8 vorgenommen, und die Kühlung der Arbeitswalzen erfolgt ein- oder beidseitig durch Kühivorrichtungen 9, 10.The deflection of the work rolls 3, 4 is controlled by an adjusting device 7, 8, and the work rolls are cooled on one or both sides by cooling devices 9, 10.
In Laufrichtung des Walzbandes 5 hinter dem Walzspalt 6 ist eine Abtasteinrichtung 11 mit einem Drehspiegel 12 und einem besonders ausgebildeten Ultrarotobjektiv 13 angeordnet, das die natürliche Infrarotstrahlung 14 des Walzbandes 5 über den Drehspiegel 12 zur Messung der Oberflächentemperatur des Bandes empfängt. Die Abtasteinrichtung 11 ist im großen Abstand von dem zu prüfenden Walzband 5 angeordnet. Das Ultrarotobjektiv 13 tastet das durchlaufende Band 5 quer zur und/ oder entlang der Laufrichtung a ab, und die aufgenommenen Temperaturänderungen werden elektronisch ausgewertet und können durch einen Impulsgeber 15 Impulse zur Regelung der Stellvorrichtungen 7, 8 für die Arbeitswalzen 3, 4 und/oder der Kühl vorrichtungen 9, 10 auslösen. Die durch äußere Störgrößen, beispielsweise durch das Walzöl oder Uldämpfe, erzeugten Spektralbereiche können durch das Einsetzen von entsprec-henden Filtern in den Strahlengang der Abtasteinrichtung 11 ausgefiltert werden. In the running direction of the rolled strip 5 behind the roll gap 6 is a Scanning device 11 with a rotating mirror 12 and a particularly trained ultrared lens 13 arranged, which the natural infrared radiation 14 of the rolled strip 5 via the rotating mirror 12 for measuring the surface temperature of the tape. The scanning device 11 is at a large distance from the one to be tested Rolled strip 5 arranged. The ultra-red lens 13 scans the running belt 5 transversely to and / or along the running direction a from, and the recorded temperature changes are evaluated electronically and a pulse generator can generate 15 pulses Control of the adjusting devices 7, 8 for the work rolls 3, 4 and / or the cooling devices 9, 10 trigger. The by external disturbances, for example by the rolling oil or Uldampf, generated spectral ranges can by the onset filtered out by appropriate filters in the beam path of the scanning device 11 will.
In Abweichung von dem beschriebenen Ausführungsbeispiel kann die Regeleinrichtung mit einer Abtasteinrichtung ausgestattet sein, die in jedem gewünschten Spektralbereich arbeitet. In a departure from the exemplary embodiment described, the Control device can be equipped with a scanning device in any desired Spectral range works.
