Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Führen von um ihre Längsachse rotierend aus einem Schrägwalzwerk, insbesondere Asselwalzwerk austretenden Luppen.The invention relates to a device for guiding rotating about its longitudinal axis blanks emerging from a cross rolling mill, in particular woodlice mill.
Die in einem Schrägwalzwerk, insbesondere Asselwalzwerk gewalzten Luppen treten mit einer bestimmten Geschwindigkeit aus dem Walzwerk aus und rotieren dabei um ihre eigene Achse. Die Bewegungen der Luppen müssen während des Walzprozesses im Auslauf durch geeignete Führungen kontrolliert oder unterstützt werden, bis sie nach Beendigung des Walzprozesses in dem nachfolgenden Rollgang weitertransportiert werden. Zur Gestaltung der Führungen im Auslauf existieren bis heute eine ganze Reihe mehr oder weniger aufwendiger Vorschläge, von denen einige realisiert und in ihrer Funktionsweise bestätigt worden sind.The blanks rolled in a cross rolling mill, in particular woodlouse mill out of the rolling mill at a certain speed and rotate around their own axis. The movements of the slugs have to be during the rolling process be controlled or supported in the outlet by suitable guides until they after completion of the rolling process in the subsequent roller table to be transported further. Up to exist for the design of the tours in the outlet today a whole series of more or less complex proposals, some of them realized and their functionality has been confirmed.
Insbesondere bei Anlagen, die Luppen mit extrem großen d/s-Verhältnissen walzen (beispielsweise d/s = 50) versagen die bekannten Auslaufführungen; denn dünnwandige Luppen können bei hohen Temperaturen nur sehr kleine Biege- und Torsionsmomente übertragen. Stößt die heiße Luppe im Auslauf nur gegen kleine Kanten oder wird die Vorwärtsbewegung anderweitig, z.B. durch Durchmesserschwankungen an der Luppe behindert, kommt es sehr schnell zu Vibrationen oder Aufstauungen, bei denen sich die Luppe wellenförmig verwirft. In der Folge entstehen Vibrationen, die so stark werden können, daß der Walzvorgang abgebrochen werden muß.Especially in systems that roll blanks with extremely high d / s ratios (for example d / s = 50) the known outlet guides fail; because thin-walled blanks can only bend very small at high temperatures Transfer torsional moments. If the hot spoon hits only small ones in the outlet Edges or will the forward movement be otherwise, e.g. by Diameter fluctuations on the slug hindered, it happens very quickly Vibrations or damming, which causes the curl to warp. In the The result is vibrations that can become so strong that the rolling process must be canceled.
Auch bei einigermaßen ruhig ablaufendem Walzvorgang steigt die zu überwindende Reibkraft mit der gewalzten Länge und damit der Masse der Luppe an. Wird die Drehbewegung der Luppe im Auslauf nicht durch entsprechende Bauteile unterstützt, kann unter Umständen die durch das Eigengewicht zu überwindende Reibkraft so groß werden, daß das übertragbare Torsionsmoment überschritten wird und die Luppe tordiert wird.Even when the rolling process is reasonably smooth, the one to be overcome increases Frictional force with the rolled length and thus the mass of the blanks. Will the Rotary movement of the slug in the outlet is not supported by corresponding components, Under certain circumstances, the friction force to be overcome by the dead weight is so great be that the transmissible torsional moment is exceeded and the brace is being murdered.
Ausgehend von den geschilderten Problemen und Nachteilen und mit der Erkenntnis, daß unsaubere Führungen im Ein- und Auslauf des Walzwerkes die Toleranzen negativ beeinflußen und dadurch die Qualität vermindern, ist es Ziel der vorliegenden Erfindung, eine Vorrichtung zum kontinuierlichen sicheren Führen der aus dem Schrägwalzwerk austretenden Luppe zu schaffen, die ein Anstoßen und Verwerfen vermeidet, die die Torsionsbeanspruchung reduziert und Schwingungen und Vibrationen weitgehend eliminiert.Based on the problems and disadvantages described and with the knowledge that that unclean guides in the inlet and outlet of the rolling mill the tolerances influence negatively and thereby reduce the quality, it is the aim of the present Invention, a device for continuous safe guiding of the Cross roll mill to create emerging slag, which is a bump and discard avoids, which reduces the torsional stress and vibrations and Vibrations largely eliminated.
Zur Lösung der Aufgabe wird erfindungsgemäß eine Vorrichtung zum Führen der Luppe vorgeschlagen, die durch mindestens zwei sich über die gesamte maximale Luppenlänge erstreckende rohrförmige Führungsrollen gekennzeichnet ist, die unterhalb der Auslaufebene der Luppe parallel zur Luppenauslaufrichtung nebeneinander um ihre Längsachse drehbar gelagert angeordnet sind.According to the invention, a device for guiding the Luppe suggested that at least two should cover the entire maximum Tube-length-extending tubular guide rollers, which is characterized below the run-out level of the blanks parallel to the blanks run-out direction are arranged side by side rotatably mounted about their longitudinal axis.
Der Grundgedanke der vorliegenden Erfindung besteht dementsprechend darin, eine durchgehende rotierende rohrförmige Führung für die auslaufende Luppe zu schaffen, die sicherstellt, daß die spiralförmig auslaufende Luppe möglichst ungehindert, jedoch optimal geführt das Walzwerk verläßt. Die durchgehenden Führungsrollen können Durchmesserschwankungen an der auslaufenden Luppe problemlos aufnehmen, eine Verdrallung bei dünnwandigen langen Luppen wird durch die rotierenden Führungsrollen sicher vermieden.The basic idea of the present invention is accordingly one to create continuous rotating tubular guide for the leaking bob, which ensures that the spirally tapering bob is as unimpeded as possible, however leaves the rolling mill optimally guided. The continuous guide roles can Easily absorb fluctuations in diameter at the outgoing die, one Twisting in thin-walled long blanks is caused by the rotating Avoid leadership roles safely.
Vorzugsweise ist vorgesehen, daß die rohrförmigen Führungsrollen jeweils stirnseitig gelagert sind, wie dies beispielsweise bei Rollenkühlbetten bereits praktiziert wird.It is preferably provided that the tubular guide rollers each have an end face are stored, as is already practiced for example with roller cooling beds.
Um die Durchbiegung der rohrförmigen Führungsrollen zwischen den Lagerungen zu verhindern ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß die Führungsrollen in Abständen durch unterhalb desselben angeordnete drehbar gelagerte Stützrollen abgestützt sind. To prevent the deflection of the tubular guide rollers between the bearings prevent is provided according to a further feature of the invention that the Guide rollers rotatable at intervals by arranged below it supported support rollers are supported.
Besonders bei sehr dünnwandigen langen Luppen kann es erforderlich sein, die Führungsrollen nicht durch die spiralförmig drehende Luppe mitnehmen zu lassen. In diesem Fall ist erfindungsgemäß vorgesehen, die rohrförmigen Führungsrollen und/oder die Stützrollen durch auf Luppenauslaufdrehzahl synchronisierte Antriebe drehanzutreiben. Dadurch werden auf die Luppe wirkende Torsionskräfte vermieden.Especially in the case of very thin-walled long blanks, it may be necessary Do not allow the guide rollers to be carried along by the spirally rotating cap. In In this case, the tubular guide rollers are provided according to the invention and / or the support rollers by drives synchronized with the die outlet speed to spin. This avoids torsional forces acting on the plate.
In einer bevorzugten Ausführungsform ist vorgesehen, daß zwei rohrförmige Führungsrollen um 30° von der horizontalen Auslaufebene versetzt beidseitig unter der Luppe angeordnet sind. In dieser Anordnung kann die Luppe gleichmäßig auf beiden Führungsrollen aufliegen und durch diese beim Auslauf abgestützt werden.In a preferred embodiment it is provided that two tubular Guide rollers offset by 30 ° from the horizontal outlet level on both sides under the Are arranged. In this arrangement, the bobbin can be spread evenly on both Guide rollers rest and are supported by them at the outlet.
Zur Einstellung der Lage der rohrförmigen Führungsrollen auf unterschiedliche Luppendimensionen ist nach einem weiteren Merkmal der Erfindung vorgesehen, die Führungsrollen auf symmetrisch zur Walzmitte angeordneten geneigten Führungsschlitten verstellbar zu lagern. Durch Verschieben der Führungsrollen auf diesen Führungsschlitten läßt sich die Höheneinstellung und gleichzeitig der Abstand der Führungsrollen voneinander variieren, so daß auch im Durchmesser stark unterschiedliche Luppen sicher geführt werden können. Insbesondere bei der Anordnung von nur zwei rohrförmigen Führungsrollen ist es sinnvoll, wenn nach einem anderen Merkmal der Erfindung, oberhalb der rohrförmigen Führungsrollen senkrecht über der Luppe mehrere an den Luppenmantel anlegbare und zum Auswerten der Luppe gemeinsam wegschwenkbare kurze Führungsrollen vorgesehen sind. Diese Führungsrollen verhindern ein seitliches Ausbrechen der auslaufenden Luppe aus der Auflage auf den rohrförmigen Führungsrollen.To adjust the position of the tubular guide rollers to different Bead dimensions is provided according to a further feature of the invention, the Guide rollers on inclined, symmetrical to the center of the roll Adjustable guide carriage. By moving the guide rollers on This slide can adjust the height and the distance at the same time the guide rollers vary from each other, so that also strong in diameter different troops can be safely guided. Especially with the Arrangement of only two tubular guide rollers, it makes sense if after one another feature of the invention, vertical above the tubular guide rollers above the flap several that can be put on the flap jacket and for evaluating the Luppe together swivel-away short guide rollers are provided. This Guide rollers prevent the leaking slug from breaking out of the side Rest on the tubular guide rollers.
Zum Abtransport der fertiggewalzten Luppe ist schließlich erfindungsgemäß vorgesehen, daß zwischen den unteren beiden rohrförmigen Führungsrollen heb- und senkbare Scheibenrollen vorgesehen sind, die jeweils um eine horizontale und quer zur Luppenauslaufrichtung verlaufende Achse drehantreibbar sind. Diese Scheibenrollen werden nach dem Wegschwenken der oberen kurzen Führungsrollen von unten eingeschwenkt und heben die Luppe von den rohrförmigen Führungsrollen ab, um sie in bekannter Weise auf den Umfangsnuten der Scheibenrollen bis zur Übergabeposition an eine Abtransporteinrichtung zu transportieren. Hiernach wird die fertiggewalzte Luppe in bekannter Weise, beispielsweise über einen Schwenkhebel ausgeworfen. Finally, according to the invention for the removal of the finished rolled billet provided that between the lower two tubular guide rollers lifting and Lowerable disc rollers are provided, each around a horizontal and transverse Axis extending to the hole outlet direction can be driven in rotation. This Disc rollers become after the upper short guide rollers are swung away swung in from below and lift the slug off the tubular guide rollers from to in a known manner on the circumferential grooves of the disc rollers up to Transport transfer position to a removal device. After that the Completely rolled billet in a known manner, for example via a swivel lever ejected.
Die vorliegende Erfindung stellt eine optimale Führungsvorrichtung für die spiralförmig auslaufenden Luppen dar und ist insbesondere für dünnwandige Luppen günstig einsetzbar. Bei diesen dünnwandigen Luppen kann die Verdrallungsgefahr in herkömmlichen Luppenführungen sicher vermieden werden, eine Gefahr des Ausknickens der Luppe besteht durch die Verwendung der durchgehenden Führung nicht mehr.The present invention provides an optimal guiding device for the spiral leaking slugs and is particularly favorable for thin-walled slugs applicable. With these thin-walled blanks, the risk of twisting in conventional guideways can be safely avoided, a danger of The bend is buckled by using the continuous guide no more.
