Abstract

A device for loading the guide surfaces of bearing chocks (LS) supported in the housing windows (SF) of rolling stands with pressure plates (DP) that can be placed on the guide surfaces and that can be loaded by a hydraulic piston (K) supported in the rolling stand housings (ST), wherein devices for measuring the pressure and devices (WM) for measuring the displacement of the piston are assigned to the hydraulic piston (K), and wherein the frictional force is eliminated by adjusting well-defined clearances between the bearing chocks (LS) and the guide surfaces.

Description

Die Erfindung betrifft eine Vorrichtung zur Beaufschlagung der Führungsflächen von, in den Ständerfenstern von Walzgerüsten geführten Lagereinbaustücken mit, auf die Führungsflächen auflegbaren Druckplatten, die von in den Walzgerüstständern angeordneten Hydraulik-Kolbenzylinder-Aggregaten beaufschlagt sind. Vorrichtungen dieser Art sind zum Beispiel aus EP-A 1 036 605 und EP-A 1 281 449 bekannt, bei denen die Hydraulik-Kolbenzylinder-Aggregate in Ausnehmungen des Walzgerüstständers angeordnet sind, und der jeweilige Zylinder-Kolben an seiner, dem Ständerfenster und der jeweiligen seitlichen Führungsfläche der Lagereinbaustücke zugewandten Stirnseite eine Druckplatte trägt. Mit dieser Vorrichtung wird die Möglichkeit geschaffen, durch Änderung der hydraulischen Druckbeaufschlagung des Kolbens definierte Anpresskräfte und damit Reibkräfte an den Lagereinbaustücken unter Überbrückung des Betriebsspiels zu erzeugen, d.h. definierte Anpress- und Reibkräfte, unabhängig von den walztechnischen Bedingungen vorzugeben. Wie in der genannten EP-A 1 036 605 beschrieben, entstehen durch die Andruckkräfte Reibkräfte, welche die gleiche Wirklinie wie die Walzkraft aufweisen. Auch wenn diese konstant gehalten werden, ist nicht gewährleistet, dass auch die Reibkräfte konstant bleiben, weil sich der Reibungskoeffizient zwischen den Anlageflächen der Lagereinbaustücke und des Ständerfensters aufgrund von Veränderungen der Oberflächenbeschaffenheit ändert. Die Oberfläche der Anlagenflächen wird durch Korrosion, Kühlwasser oder andere Abrassivstoffe rauer. Der Reibungskoeffizient steigt an und damit auch die Reibkräfte T, die dadurch nur ungenau bestimmbar sind. Unabhängig davon, ob die Reibkräfte bestimmbar sind, oder nicht, beeinträchtigen sie die Steuer- und Regelbarkeit der Walzgerüste. Infolge dessen ist die direkt im Walzspalt wirkende Walzkraft nicht genau bestimmbar. Aber nur aus dieser direkt im Walzspalt wirksamen Kraft kann nach der Dickenregelungsgleichung die aktuelle Banddicke im Walzspalt berechnet werden. Infolge dessen sind die Band-Dicken- und Band-Planheitstoleranzen schwierig einzuhalten. Mit der konstruktiven Lösung nach der genannten Druckschrift lässt sich auch nicht feststellen, wo sich die Mittelebenen der Lagereinbaustücke im Ständerfenster mit Bezug auf eine fixe Ebene befinden und wie sich die Lage der Mittelebenen zu dieser fixen Ebene verändert. Dieser Mangel führt auch dazu, dass ein unbeabsichtigtes Schränken der Walzen gegeneinander nicht feststellt werden kann.The invention relates to a device for acting on the guide surfaces of, guided in the stator windows of rolling stands bearing chocks with auflegbaren on the guide surfaces printing plates, which are acted upon by arranged in the rolling mill stands hydraulic piston-cylinder units. Devices of this kind are for example off EP-A 1 036 605 and EP-A 1 281 449 known, in which the hydraulic piston-cylinder units are arranged in recesses of the roll stand, and the respective cylinder piston carries on its, the stator window and the respective lateral guide surface of the bearing chocks facing end face a pressure plate. With this device, the possibility is created to produce by changing the hydraulic pressure of the piston defined contact forces and thus frictional forces on the bearing chocks while bridging the operating clearance, ie defined Anpress- and friction forces, regardless of the rolling technical conditions. As in the mentioned EP-A 1 036 605 described, caused by the Andruckkräfte frictional forces, which have the same line of action as the rolling force. Even if they are kept constant, it is not guaranteed that the frictional forces remain constant because the coefficient of friction between the bearing surfaces of the bearing chocks and the stator window changes due to changes in the surface condition. The surface of the plant surfaces becomes rougher due to corrosion, cooling water or other abrasive substances. The coefficient of friction increases and thus also the frictional forces T, which are therefore only vaguely determinable. Regardless of whether the friction forces are determinable or not, they affect the controllability of the rolling stands. As a result, the rolling force acting directly in the nip can not be accurately determined. But only from this directly effective in the nip force can according to the thickness control equation the actual strip thickness in the roll gap can be calculated. As a result, the strip thickness and strip flatness tolerances are difficult to maintain. With the constructive solution according to the cited document can also not determine where the center planes of the bearing chocks in the stator window with respect to a fixed plane and how the position of the center planes changed to this fixed plane. This lack also leads to the fact that unintentional locking of the rollers against each other can not be determined.

Der Erfindung liegt die Aufgabe zugrunde, diese, den Walzprozeß beeinträchtigenden Nachteile zu beseitigen. Diese Aufgabe wird dadurch gelöst, dass dem Hydraulikzylinder jeweils, von Regeleinrichtungen steuerbare Druck- und Wegmesseinrichtungen zugeordnet werden. Diese Regelungen können derart arbeiten, dass der Kolben unabhängig von der auf ihn wirkenden Kraft eine vorgegebene Position einhält oder so, dass er bei einer bestimmten, auf den Kolben wirkenden Kraft ausweicht, und eine andere bestimmte Position anfährt; sie können auch so arbeiten, dass das Lagereinbaustück mit einer bestimmten Kraft an eine fixe Ständerfensterseite angedrückt wird. Der Weggeber zeigt dann keine Veränderungen mehr an. Wird der Kolben des Zylinders dann um einen vorgegebenen Betrag in die entgegengesetzte Richtung gefahren, so entsteht ein definiertes Spiel der Lagereinbaustücke im Ständerfenster. Diese Art der Spieleinstellung kann die Fertigungstolleranzen der unterschiedlichen Lagereinbaustücke, den Verschleiß und die Ständereinschnürung aufgrund der zu erwartenden Walzkräfte kompensieren. Durch das Einstellen eines optimalen Spiels wirken keine Andruckkräfte des Kolbens und es werden keine Reibkräfte erzeugt, welche die Regelbarkeit des Prozesses negativ beeinflussen.The invention has for its object to eliminate this, affecting the rolling process disadvantages. This object is achieved in that the hydraulic cylinders are each assigned control devices which can be controlled by pressure and displacement measuring devices. These arrangements may operate such that the piston, regardless of the force acting on it, maintains a predetermined position or so as to yield at a certain force acting on the piston, and approaches another particular position; they can also work so that the bearing insert is pressed with a certain force to a fixed stand window side. The Weggeber then shows no changes. If the piston of the cylinder is then driven by a predetermined amount in the opposite direction, so there is a defined game of bearing chocks in the stator window. This type of clearance adjustment can compensate for the manufacturing tolerances of the different bearing chocks, the wear and the Ständereinschnürung due to the expected rolling forces. By setting an optimal game no pressure forces of the piston and no frictional forces are generated, which negatively affect the controllability of the process.

Bei bekannter Lage der Ständerfensterseiten kann durch das Andrücken und das gleichzeitige Messen des gefahrenen Kolbenhubs auf der Antriebsseite sowie auf der Bedienungsseite der Walzen die Lage der Lagereinbaustücke zu einer gewählten Ebene bestimmt werden. Wird diese Wegmessung mit vorher gespeicherten Wegmessungen verglichen, dann lässt sich der Verschleiß an den Ständerfenstern und deren Einbauteilen ermitteln. Wird der Kolben wie beschrieben so eingesetzt, dass pro Walze zwei Kolben vorhanden sind und diese über die Lagereinbaustücke auf eine fixe Fläche drücken, lässt sich damit die Schränkung der Walzen ermitteln. Durch die Auswertung der Messwerte kann dabei die Lage aller Walzen untereinander bestimmt werden. Wenn für jedes Lagereinbaustück auf jeder Seite, der Einlauf- und der Auslaufseite sowie der Antriebs- und Bedienungsseite ein Kolben vorgesehen ist, können über diese Wegemessung die Walzen gezielt gegeneinander verschränkt werden. So können z. B. die obere Arbeitswalze und die obere Stützwalze parallel zueinander gestellt werden und gegenüber der unteren Arbeitswalze und der unteren Stützwalze, die für sich parallel zueinander gestellt sind verschränkt werden. Diese Schränkung der oberen Walzen zu den unteren Walzen kann dann zur Beeinflussung von Profil und Planheit genutzt werden. Mit Hilfe dieser integrierten Wegmessung, die unmittelbar in oder an den bewegten Bauteilen misst, lässt sich die Lage der Walzen genau positionieren.In a known position of the stator window sides, the position of the bearing chocks can be determined to a selected level by pressing and simultaneously measuring the driven piston stroke on the drive side and on the operating side of the rollers. If this distance measurement compared with previously stored distance measurements, then the wear can be determine the stud windows and their components. If the piston is used as described so that there are two pistons per roller and they press over the bearing chocks on a fixed surface, so that the setting of the rollers can be determined. By evaluating the measured values, the position of all rolls can be determined among each other. If a piston is provided for each bearing chock on each side, the inlet and the outlet side and the drive and operating side, the rollers can be selectively interlocked against each other via this path measurement. So z. B. the upper work roll and the upper support roller are placed parallel to each other and compared to the lower work roll and the lower support roller, which are placed parallel to each other are entangled. This setting of the upper rolls to the lower rolls can then be used to influence profile and flatness. With the aid of this integrated displacement measurement, which measures directly in or on the moving components, the position of the rollers can be precisely positioned.
