Regeleinrichtung für WalzgerüsteControl device for roll stands

Die Erfindung bezieht sich auf eine Regeleinrinhtung für Walzgerüste, insbesondere hydraulisch vorgespannte Walzgerüste zur Erzielung gleichbleibender Banddicke des ausge- - brachten Walzgutes·The invention relates to a control unit for Roll stands, in particular hydraulically pre-tensioned roll stands to achieve consistent strip thickness of the - brought rolling stock

Bei den bekannten Regeleinrichtungen dieser Art sind Kraftmeßeinriohtungen vorgesehen, die die vom Walzgut auf die Walzen ausgeübte Rückstellkraft messen und das Meßergebnis als Regelgröße für die Walzenanstellung verwenden. Hierbei können zwar bestenfalls Diokenabweichungen des einlaufenden Walzgutes ausgeregelt werden, nicht aber Uhrundheiten der Walzen und Inhomogenitäten im Material des Walzgutes. Besonders bei hydraulisch vorgespannten Walzgerüsten werden diese Störeinflüsse bei Verwendung derartiger Regeleinrichtungen noohfc verstärkt. Diese Nachteile zu beseitigen, ist Aufgabe der vorliegenden Erfindung.In the known control devices of this type, force measuring devices are used provided, which measure the restoring force exerted by the rolling stock on the rolls and the measurement result as a controlled variable use for roller adjustment. In this case, at best, discrepancies in the incoming rolling stock can be corrected but not clock irregularities of the rolls and inhomogeneities in the material of the rolling stock. Especially with hydraulic With prestressed roll stands, these disruptive influences are amplified when using such control devices. The object of the present invention is to eliminate these disadvantages.

Danach wird vorgeschlagen, daß eine den Abstand der Arbeitswalzen berührungslos messende Meßeinrichtung über eine Sollwertvergleichstufe und einen Stellgrößengeber mit einer hydjtraulischen Stelleinrichtung verbunden ist, welche den Walzspalt auf die Sollgröße einregelt. Mittels einer solchen Regelung ist es möglich, Walzgut auszubringen, das eine gleichbleibende Bandjo dicke aufweist. Die berührungslose Messung des Walzspaltes gewährleistet eine sehr schnelle Regelung und Kompensation von Störeinflüssen.It is then proposed that a distance between the work rolls Contactless measuring device via a setpoint comparison stage and a manipulated variable with a hydraulic Adjusting device is connected, which regulates the roll gap to the target size. It is by means of such a scheme possible to apply rolling stock that has a constant Bandjo thickness. The non-contact measurement of the roll gap is guaranteed a very fast regulation and compensation of disturbances.

Als Meßeinrichtung für die berührungslose Messung des Arbeitswalzenabstandes können vorteilhaft lichtelektrische oder elektromagnetische Impulsgeber verwendet werden. Die Geber können vorAs a measuring device for the non-contact measurement of the work roll distance can advantageously be photoelectric or electromagnetic Pulse generator can be used.

oder hinter dem Walzspalt oder an den Einbaustüoken angeordnet sein. Es kann also eine Stelle ausgewählt werden, an der die Geber vor Beschädigungen während des Walzbetriebes weitgehend geschützt sind.or arranged behind the roll gap or on the installation pieces be. A point can therefore be selected at which the encoder is largely protected from damage during the rolling operation are protected.

ο Gemäß einem weiteren Schritt der vorliegenden Erfindung wird vorgeschlagen, die Meßeinrichtung beispielsweise durch Anordnung mehrerer Meßpunkte über die Länge des Walzspaltes so auszu» bilden, daß sie auch eine Durchbiegung der Arbeitswalzen ermittelt» und z.B. über eine Walzenbiegevorrichtung ausgleicht· Dadurch wird nicht nur eine gute Maßhaltigkeit des Walzgutes in Walzrichtung sondern auch eine gleichbleibende Banddicke in Querrichtung erzielt.ο According to a further step of the present invention proposed to design the measuring device for example by arranging several measuring points over the length of the roll gap so » form that it also determines deflection of the work rolls » and, for example, compensates with a roll bending device · This not only ensures good dimensional accuracy of the rolling stock in the rolling direction but also a constant tape thickness in the transverse direction is achieved.

Zusätzlich zu der beschriebenen Meßeinrichtung für den Abstand der Arbeitswalzen kann eine weitere Meßvorrichtung zu Ermittlung ο der Banddicke des ausgebrachten Walzgutes vorgesehen sein, mittels derer die Funktion der Regeleinrichtung überwacht werden kann und die ggf· eine Nachregelung der Sollwertvorgabe ermöglichet·In addition to the described measuring device for the distance between the work rolls, a further measuring device can be used to determine ο the strip thickness of the rolled stock must be provided, by means of which the function of the control device can be monitored and which, if necessary, enables readjustment of the setpoint specification

Die Stützwalzen 1 sind in Stützwalzeneinbaustücken 2 gelagert· Die zwischen den Stutzwalzen 1 liegenden Arbeitswalzen 3 sind in Arbeitswalzenelnbaustücken 4 gelagert· Pur die Walzenanstellung ist eine hydraulisch angetriebene Stelleinrichtung 5 an Jeder Walzgerüstseite vorgesehen· Eine berührungslos arbeitende Meßeinrichtung 6 an den Enden der Arbeitswalzen J> dient der Ermittlung der Größe des Walzspaltes. Das Ist - Signal 7 der Meßeinrichtung 6 wird einer Sollwertvergleichsstufe 8 zugeführt und mit dem Sollwert 9 verglichen. Das so ermittelte Differenzsignal Io wird in einem Stellgrößengeber 11 in hydraulische Impulse 12 umgewandelt, mittels derer Über die Stelleinrichtung der Walzspalt geregelt wird.The supporting rollers 1 are mounted in back-up roll chocks 2 · The lying between the stub rolls 1 work rolls 3 are in the work roll ENEL chocks 4 mounted · Pur the roll setting a hydraulically driven adjusting device 5 is provided on each rolling stand side · A non-contact measuring means 6 is used at the ends of the work rolls J> determining the size of the roll gap. The actual signal 7 of the measuring device 6 is fed to a nominal value comparison stage 8 and compared with the nominal value 9. The difference signal Io determined in this way is converted in a manipulated variable generator 11 into hydraulic pulses 12, by means of which the roll gap is regulated via the adjusting device.
