Description
Technisches GebietTechnical area
Die Erfindung betrifft eine Walzvorrichtung nach dem Oberbegriff von Anspruch 1 und ein Verfahren für deren Betrieb nach Anspruch 5.The The invention relates to a rolling device according to the preamble of Claim 1 and a method for its operation according to claim 5th
Stand der TechnikState of the art
Walzvorrichtungen sind im Stand der Technik hinlänglich bekannt. Dabei sind beispielsweise solche Walzvorrichtungen bekannt, bei welchen ein Paar von Arbeitswalzen von zumindest zwei gegenüber den Arbeitswalzen größeren Stützwalzen zur Aufnahme der Walzkräfte beaufschlagt werden. Bei solchen Walzvorrichtungen ist es weiterhin bekannt, dass die Planheit des Walzguts variieren kann, wodurch ein Materialrückstau unmittelbar vor dem Walzspalt zwischen den Arbeitswalzen entstehen kann. Kann der Materialrückstau nicht rechtzeitig und genau genug ausgeglichen werden, entstehen Ungleichmäßigkeiten in der Planheit des gewalzten Materials, was zu Qualitätseinbußen des Walzguts führt und wodurch das Walzgut ggf. für manche Anwendungsfälle gänzlich ungeeignet wird.rolling devices are well known in the art. There are For example, such rolling devices are known in which a pair of work rolls of at least two opposite the work rolls larger support rollers for receiving the Walzkräfte be acted upon. In such rolling devices It is also known that the flatness of the rolled stock vary can, causing a material backlog immediately before the Rolling gap between the work rolls can arise. Can the material backlog not be balanced on time and exactly enough, arise Unevenness in the flatness of the rolled Material, resulting in reduced quality of the rolling stock leads and whereby the rolling stock if necessary for some Use cases completely unsuitable.
Im
Stand der Technik sind Walzvorrichtungen bekannt, bei welchen Planheitsmessungen
mittels Zugrollen zur Ermittlung der Zugspannungsverteilung durchgeführt
werden. Solche Zugrollen sind jedoch typischer Weise weit von den
Arbeitswalzen entfernt angeordnet, so dass der Materialrückstau vor
dem Walzspalt damit nicht zuverlässig ermittelt werden
kann. Eine solche Walzvorrichtung ist beispielsweise durch die
Die
Andere Walzvorrichtungen messen die Planheit lediglich in einer weiteren Entfernung hinter dem Walzspalt, was dazu führt, dass die Ergebnisse zur Regelung der Planheit durch Planheitsstellglieder verwendet werden. Allerdings wirken sich Fehleinstellungen des Walzgerüsts nicht immer genügend auf die auslaufseitigen Messungen aus oder es kann aufgrund der dadurch entstehenden Verzögerung nicht schnell genug auf Profil- oder Planheitsänderungen reagiert werden kann, so dass die ermittelten Planheitsabweichungen nicht mehr korrigiert werden können, weil sie bereits hinter dem Walzspalt entstanden sind.Other Rollers measure the flatness only in another Distance behind the nip, which causes the Results used to control the flatness by planarity actuators become. However, incorrect settings of the roll stand not always enough on the outlet side measurements or it can not because of the resulting delay fast enough to respond to profile or flatness changes can be, so that the determined flatness deviations are not can be corrected more because they are already behind the nip have arisen.
Darstellung der Erfindung, Aufgabe, Lösung, VorteilePresentation of the invention, problem, solution, advantages
Es ist die Aufgabe der vorliegenden Erfindung, eine Walzvorrichtung mit einer Messvorrichtung und ein Verfahren hierfür zu schaffen, bei welcher ein Materialrückstau sicher erkannt wird und dadurch eine Regelung/Steuerung zur Vermeidung von dadurch entstehenden Planheitsdefiziten bis hin zu instabilen Walzzuständen (Kneifer, Überwalzungen u. ä.) durchführbar ist.It The object of the present invention is a rolling device with a measuring device and a method for this create, in which a backwater reliably detected and thereby a control to avoid it resulting flatness deficits to unstable rolling conditions (Pincers, Überwalzungen and the like) feasible is.
Erfindungsgemäß wird die Aufgabe bezüglich der Walzvorrichtung erreicht, durch eine Walzvorrichtung gemäß der Merkmalen von Anspruch 1 mit Walzvorrichtung mit zumindest zwei Arbeitswalze und einem Walzspalt zwischen den Arbeitswalzen zum Durchführen und Walzen eines Walzguts, wie beispielsweise eines Bandes vorzugsweise aus Metall, und gegebenenfalls einer Anordnung von Stützwalzen, wobei weiterhin zumindest eine Messvorrichtung vorgesehen ist zum Messen eines Rückstaus des Walzmaterials des Walzguts vor dem Walzspalt, wobei weiterhin eine Steuer- oder Regeleinheit vorgesehen ist, welche aufgrund der Signale der Messvorrichtung Stellglieder zur Einstellung der Planheit des Walzguts ansteuert.According to the invention achieved the task with respect to the rolling device, by a rolling device according to the features of claim 1 with rolling device with at least two work rolls and a Rolling gap between the work rolls for performing and Rolling a rolling stock, such as a belt, preferably of metal, and possibly an arrangement of back-up rolls, wherein furthermore at least one measuring device is provided for Measuring a backlog of the rolling stock of the rolling stock before the nip, further provided with a control unit which is due to the signals of the measuring device actuators for adjusting the flatness of the rolling stock.
Dabei ist es vorteilhaft, wenn weiterhin nach dem Walzspalt eine Planheitsmessvorrichtung vorgesehen ist, welche ebenfalls Signale für die Steuer- oder Regeleinheit zur Verfügung stellt, worauf hin diese im Ansprechen auf die Signale der Messvorrichtung und der Planheitsmessvorrichtung die Stellglieder zur Einstellung der Planheit des Walzguts ansteuert.there it is advantageous if, further after the nip, a flatness measuring device is provided, which also signals for the control or Control unit provides, what this in the In response to the signals of the measuring device and the flatness measuring device controls the actuators to adjust the flatness of the rolling stock.
Auch ist es zweckmäßig, wenn ein Stellglied zur Einstellung der Planheit des Walzguts ein Stellglied zur Einstellung der Schräglage der Arbeitswalzen und/oder der Zwischenwalzen und/oder der Stützwalzen, der Biegung der Arbeitswalzen und/oder der Zwischenwalzen, und/oder der Stützwalzen, der Axialverschiebung der Arbeitswalzen und/oder der Zwischenwalzen, beispielsweise im Rahmen einer Continuously Variable Crown-(CVC)-Verschiebung, einer Minimalmengenschmierung und/oder einer Temperatursteuerung oder Temperaturregelung des Bandes und/oder der Arbeitswalzen ist. Dadurch kann die gewünschte Planheit bevorzugt beeinflusst und eingestellt werden.Also it is useful if an actuator for adjustment the flatness of the rolling stock is an actuator for adjusting the inclined position the work rolls and / or the intermediate rolls and / or the backup rolls, the bending of the work rolls and / or the intermediate rolls, and / or the back-up rolls, the axial displacement of the work rolls and / or the intermediate rolls, for example in the context of a Continuously Variable Crown (CVC) displacement, a minimum quantity lubrication and / or a temperature control or temperature control of the belt and / or the work rolls. This can provide the desired flatness preferably be influenced and adjusted.
Dabei ist es vorzugsweise vorteilhaft, wenn die zumindest eine Messvorrichtung zum Messen eines Rückstaus des Walzmaterials des Walzguts vor dem Walzspalt eine optisch oder mechanisch messende Messvorrichtung ist.there It is preferably advantageous if the at least one measuring device for measuring a backlog of the rolled material of the rolling stock before the nip an optically or mechanically measuring device is.
Erfindungsgemäß wird die Aufgabe bezüglich des Verfahrens erreicht, durch ein Verfahren zum Betreiben einer Walzvorrichtung gemäß Anspruch 5. Die Vorteile dieses Verfahrens entsprechen den oben mit Bezug auf die Vorrichtung angegebenen Vorteilen.According to the invention the task with respect to the method achieved by a A method of operating a rolling apparatus according to claim 5. The advantages of this method are the same as those described above On the device indicated advantages.
Auch ist es zweckmäßig, wenn die zumindest eine Messvorrichtung zum Messen eines Rückstaus des Walzmaterials des Walzguts vor dem Walzspalt den Rückstau optisch oder mechanisch detektiert.Also it is expedient if the at least one measuring device for measuring a backlog of the rolled material of the rolling stock before the roll gap, the backlog optically or mechanically detected.
