Abstract

Roller-cooling and/or lubricating device comprises a crosspiece (9) assigned to the rollers (3-6) and having spray nozzles (8) for introducing cooling and lubricating materials, especially rolling oil and/or emulsions. The spray nozzles have a valve equipped with a piezo-actuator as adjusting part.

Description

Die Erfindung betrifft eine Walzenkühl- und/oder Schmiervorrichtung für Walzwerke, insbesondere Feinband- und Folienwalzwerke, mit den einzelnen Walzen zugeordneten Düsenbalken, auf denen über die Walzenbreite Sprühdüsen angeordnet sind, insbesondere zur Regelung der Bandzugspannung über die Bandbreite durch eine Änderung des wirksamen Walzenballendurchmessers und/oder eine Beeinflussung der Walzenschmierung mit einer druck- und/oder mengen- und/oder temperaturgesteuerten Zuführung von Kühl- und Schmiermittel, insbesondere Walzöl bzw. Emulsionen.The invention relates to a Walzenkühl- and / or Lubricating device for rolling mills, in particular Feinband- and Foil mills, associated with the individual rolls Nozzle bars on which over the roll width spray nozzles are arranged, in particular for controlling the strip tension over the bandwidth by changing the effective one Roll bale diameter and / or an influence of Roller lubrication with a pressure and / or quantity and / or temperature-controlled supply of coolants and lubricants, in particular rolling oil or emulsions.

Eine in der DE 201 06 972 U1 beschriebene Walzenkühlund/oder Schmiervorrichtung der gattungsgemäßen Art ist mit Sprühdüsen ausgerüstet, deren druckluftbetätigte Düsenventile durch Elektromagnetventile gesteuert werden. Die Düsenventile müssen angesteuert von Planheitsmeßsystemen in kurzen Zeitintervallen, die unter 50 Millisekunden liegen sollen, öffnen und schließen. Diese kurzen Taktzeiten können mit den Düsenventilen der Sprühdüsen der gattungsgemäßen Walzenkühlund/oder Schmiervorrichtung aufgrund der zu bewegenden Massen nicht verwirklicht werden.A roller cooling system described in DE 201 06 972 U1 and / or Lubricating device of the generic type is with Spray nozzles equipped, the pressure-operated nozzle valves be controlled by solenoid valves. The nozzle valves must be controlled by flatness measuring systems in short Time intervals that should be less than 50 milliseconds, open and close. These short cycle times can be combined with the Nozzle valves of the spray nozzles of the generic Walzenkühlund and / or Lubricating device due to the masses to be moved not be realized.

Der Erfindung liegt die Aufgabe zugrunde, ein Düsenventil mit sehr kurzen Schaltzeiten für die Sprühdüsen einer gattungsgemäßen Walzenkühl- und/oder Schmiervorrichtung für Walzwerke zu entwickeln. The invention is based on the object, a nozzle valve with very short switching times for the spray nozzles one generic roller cooling and / or lubricating device for To develop rolling mills.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine gattungsgemäße Walzenkühl- und/oder Schmiervorrichtung mit Sprühdüsen, deren Düsenventile mit einem Piezo-Aktor als Stellglied ausgestattet sind.This object is achieved by a generic roller cooling and / or lubricating device with Spray nozzles whose nozzle valves with a piezo actuator as Actuator are equipped.

Für Piezo-Aktoren wird meist polykristallines Keramikmaterial verwendet, das sich deformiert, wenn eine elektrische Ladung auf die Keramikoberfläche gebracht wird. Bei Anlegen einer Wechselspannung beginnt der Piezo-Aktor zu schwingen. Diese mit einer sehr hohen Frequenz ablaufende Schwingbewegung wird zum Öffnen und Schließen der Düsenventile der Sprühdüsen genutzt.For piezo actuators is usually polycrystalline Used ceramic material that deforms when a electric charge is placed on the ceramic surface. at Applying an AC voltage starts the piezo actuator too swing. This is running at a very high frequency Oscillation is used to open and close the nozzle valves used the spray nozzles.

Die in der Zeichnung dargestellte Walzenkühl- und Schmiervorrichtung 1 für ein Quartowalzgerüst 2, das eine untere und eine obere Arbeitswalze 3, 4 sowie eine untere und eine obere Stützwalze 5, 6 aufweist, ist mit zwei den Arbeitswalzen 3, 4 zugeordneten Düsenbalken 7, 7 mit in drei Reihen übereinander angeordneten Sprühdüsen 8 und zwei den Stützwalzen 5, 6 zugeordneten Düsenbalken 9 mit einreihig angeordneten Sprühdüsen 8 ausgestattet, deren Düsenventile durch die vorgeschriebenen Piezo-Aktoren geöffnet und geschlossen werden.The Walzenkühl- and shown in the drawing Lubricating device 1 for a 4-high stand 2, which has a lower and an upper work roll 3, 4 and a lower and a upper back-up roll 5, 6 is two with the work rolls 3, 4 associated nozzle bars 7, 7 with in three rows superimposed spray nozzles 8 and two the support rollers 5, 6 associated nozzle beam 9 arranged in a single row Spray nozzles 8 equipped, the nozzle valves through the required piezo actuators are opened and closed.
