Abstract
Description
Die Erfindung bezieht sich auf ein Walzgerüst mit Stütz- und/oder Arbeitswalzen zum Walzen von Blechen oder Bändern, mit wenigstens einem zwischen Einbaustücken einer der Walzen angeordnetem, vorzugsweise der oberen Walze zugeordnetem Walzbalken und mit benachbart dem Walzbalken angeordneter Einlauf-/Auslaufführung für ein Medium, z.B. Kühlwasser od. dgl., sowie mit Dichtmitteln zur Verhinderung Herabtropfens des Mediums auf das Walzgut.The invention relates to a roll stand with support and / or work rolls for rolling sheets or strips, with at least one arranged between chocks of one of the rolls, preferably the upper roll associated rolling beam and adjacent to the rolling beam arranged inlet / outlet guide for a medium , eg Cooling water od. Like., And with sealants to prevent dripping of the medium on the rolling stock.
Grundsätzlich besteht bei Walzgerüsten mit Stütz- und/oder Arbeitswalzen zum Walzen von Blechen oder Bändern ein Bedarf, Medien wie z.B. Walzenkühlwasser, Emulsion etc. vor dem Herabtropfen zwischen den Einlauf-/Auslaufführungen und den Walzen/Walzenarmaturen zu beseitigen. Es sind dazu aus dem Stand der Technik mehrere Anordnungen von Walzgerüsten bekannt, bei denen Abdichteinrichtungen zu diesem Zweck vorgesehen sind, wobei zumeist z.B. V- förmige Dichtungen, vorzugsweise aus Gummi, in vertikaler Richtung eingesetzt wurden, die jedoch insbesondere in Warmwalzwerken einem erhöhten Verschleiß unterliegen. Es sei dazu zum Stand der Technik auf folgende Druckschriften verwiesen:Basically, there is a need for rolling stands with support and / or work rolls for rolling sheet or strip, media such as e.g. Roll cooling water, emulsion, etc. to eliminate before dripping between the inlet / outlet guides and the rollers / roller fittings. There are known from the prior art several arrangements of rolling stands, in which sealing means are provided for this purpose, wherein in most cases e.g. V-shaped seals, preferably made of rubber, were used in the vertical direction, but in particular in hot rolling mills are subject to increased wear. Reference is made to the prior art to the following documents:
In der
Die
Bei den bekannten Anordnungen ist wie erwähnt insbesondere nachteilig, das die verwendeten Abdichtelemente einem erhöhten Verschleiß unterliegen bzw. geringe Standzeiten aufweisen.In the known arrangements, as mentioned, it is particularly disadvantageous that the sealing elements used are subject to increased wear or have short service lives.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, die bekannten Anordnungen unter Beibehaltung der bisherigen Vorteile in der Weise zu verbessern bzw. weiterzuentwickeln, dass mit einfachen Mitteln Medien wie z.B. Walzenkühlwasser, Emulsion etc. vor dem Herabtropfen zwischen den Einlauf-/Auslaufführungen und den Walzen/Walzenarmaturen beseitigt werden, wobei die gewünschte Anordnung möglichst einfach aufgebaut sein und einem möglichst geringen Verschleiß unterliegen soll.Based on this, the object of the invention is to improve or further develop the known arrangements while retaining the previous advantages in such a way that media such as e.g. Roll cooling water, emulsion, etc. are eliminated before dripping between the inlet / outlet guides and the rollers / roller fittings, the desired arrangement should be as simple as possible and subject to the least possible wear.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Dichtmittel zur Verhinderung des Herabtropfens des Mediums insbesondere auf das Walzgut als wenigstens eine zwischen dem Walzbalken und der Einlauf-/Auslaufführung angeordnete Dichtleiste ausgebildet ist.The object is achieved in that the sealing means for preventing the dripping of the medium is formed in particular on the rolling stock as at least one arranged between the rolling beam and the inlet / outlet guide sealing strip.
Auf diese Weise wird erstmalig mit einfachen Mitteln ein solches Walzgerüst geschaffen, bei dem Medien, wie z.B. Walzenkühlwasser, Emulsion etc. vor dem Herabtropfen zwischen den Einlauf-/Auslaufführungen und den Walzen/Walzenarmaturen beseitigt werden, es wird dabei beim Anpressen der Einlauf-/Auslaufführungen der Spalt zwischen Walzbalken und Einlauf-/Auslaufführungen durch die Dichtleiste abgedichtet, wodurch die genannten Medien vor dem Herabtropfen auf das Walzgut zurückgehalten werden. Durch die erfindungsgemäße Anordnung ergibt sich dabei eine besonders günstige sowie auch robuste, verschleißarme und zuverlässige Lösung.In this way, such a rolling stand is created for the first time with simple means in which media, such as roller cooling water, emulsion, etc. are eliminated before dripping between the inlet / outlet guides and the rollers / roller fittings, it is doing while pressing the inlet / exit guides the gap between rolling beam and inlet / outlet guides sealed by the sealing strip, whereby the said media are retained on the rolling stock before dripping. The inventive arrangement results in a particularly favorable as well as robust, low-wear and reliable solution.
Bei der bevorzugten Ausführungsform der vorliegenden Erfindung ist die Dichtleiste in einer im Bereich zwischen dem Walzbalken und der Einlauf-/Auslaufführung angeordneten Aufnahmenut angeordnet. Dabei ist in bevorzugter Ausgestaltung die Aufnahmenut im Walzbalken angeordnet. Dies ist eine konstruktiv einfache Ausführungsform, bei der die Dichtleiste in einfacher Weise zur Abdichtung aus der Aufnahmenut heraus gedrückt werden kann.In the preferred embodiment of the present invention, the sealing strip is arranged in a receiving groove arranged in the region between the rolling beam and the inlet / outlet guide. In this case, the receiving groove is arranged in the rolling beam in a preferred embodiment. This is a structurally simple embodiment in which the sealing strip can be pressed in a simple manner for sealing out of the receiving groove.
Nach einem weiteren Ausgestaltungsmerkmal der vorliegenden Erfindung ist vorgesehen, dass die Dichtleiste in der Aufnahmenut gegen den Walzbalken vorgespannt gelagert ist. Die Dichtleiste erfüllt dadurch ohne weitere Einstellarbeiten die geforderte Dichtwirkung zwischen den Einlauf-/Auslaufführungen und dem Walzenbalken. Dabei empfiehlt es sich, dass zur Vorspannung der Dichtleiste in der Aufnahmenut wenigstens eine Federeinrichtung vorgesehen ist. Über diese Federeinrichtung wird dabei beim Anpressen der Einlauf-/Auslaufführungen der Spalt zwischen Walzbalken und Einlauf-/Auslaufführungen eben durch die federbelastete Dichtleiste abgedichtet, wodurch die genannten Medien vor dem Herabtropfen auf das Walzgut zurückgehalten werden.According to a further embodiment feature of the present invention it is provided that the sealing strip is mounted biased in the receiving groove against the rolling beam. The sealing strip thus fulfills the required sealing effect between the inlet / outlet guides and the roller bar without any further adjustment work. It is recommended that at least one spring device is provided for biasing the sealing strip in the receiving groove. About this spring device is thereby sealed when pressing the inlet / outlet guides the gap between the rolling beam and inlet / outlet guides just by the spring-loaded sealing strip, whereby the media are retained against dripping on the rolling stock.
In davon abweichender Ausgestaltung des erfindungsgemäßen Walzgerüstes ist aber auch vorgesehen, dass zur Vorspannung der Dichtleiste in der Aufnahmenut ein Pneumatiksystem oder ein Hydrauliksystem vorgesehen ist.In deviating embodiment of the rolling mill according to the invention but also provided that for biasing the sealing strip in the receiving groove, a pneumatic system or a hydraulic system is provided.
Es empfiehlt sich nach einem weiteren Ausgestaltungsmerkmal der vorliegenden Erfindung, dass die Anordnung der Dichtleiste in der Aufnahmenut eine Rückhalteeinrichtung für die Dichtleiste umfasst, über diese kann die Dichtleiste gewünschtenfalls in Nichtfunktionslage gehalten werden. In bevorzugter Ausgestaltung ist dabei nach einem letzten Merkmal der vorliegenden Erfindung vorgesehen, dass die Rückhalteeinrichtung für die in der Aufnahmenut angeordnete Dichtleiste als wenigstens eine Schraube ausgebildet ist.It is recommended according to a further embodiment feature of the present invention, that the arrangement of the sealing strip in the receiving groove comprises a retaining device for the sealing strip, on these, the sealing strip if necessary, be kept in a non-operational position. In a preferred embodiment, it is provided according to a last feature of the present invention that the retaining device is designed for the arranged in the receiving groove sealing strip as at least one screw.
