Description
Die Erfindung betrifft eine Abwickelvorrichtung und ein Verfahren zum Abwickeln eines zu einem Coil aufgewickelten Bandes zu dessen Warmwalzen.The invention relates to an unwinding device and a method for unwinding a wound into a coil strip for its hot rolling.
In Warmwalzanlagen werden vorgewalzte Bänder oft zu einem so genannten Coil aufgewickelt. Zum Auf- und/oder Abwickeln von Bändern werden Auf- und/oder Abwickelvorrichtungen verwendet, die auch als Coilboxen bezeichnet werden. Warmwalzanlagen mit Coilboxen bieten Vorteile bezüglich über die Bandlänge gleich bleibender Temperatur, Walzgeschwindigkeit und Walzkraft. Beim Warmwalzen wird einerseits zunehmend immer festeres Material produziert und andererseits die maximale Banddicke, insbesondere für Röhrengüten, erhöht. Eine Methode, die Festigkeit und Zähigkeit des Materials zu erhöhen, ist beispielsweise die thermomechanische Walzung, bei der mit sehr kleinen Temperaturen in einer Fertigstraße gewalzt wird. Durch die Erhöhung der Festigkeit und Dicke und/oder die Verringerung der Temperatur der Bänder besteht zunehmend Bedarf, dickere, kältere und festere Vorstreifen in einer Coilbox auf- und/oder abzuwickeln.In hot rolling plants, pre-rolled strips are often wound into a so-called coil. For winding and / or unwinding of tapes up and / or unwinding devices are used, which are also referred to as coil boxes. Hot rolling mills with coil boxes offer advantages in terms of the strip length constant temperature, rolling speed and rolling force. When hot rolling, on the one hand increasingly solid material is increasingly produced and on the other hand, the maximum strip thickness, especially for tube grades, increased. One method of increasing the strength and toughness of the material is, for example, thermomechanical rolling, which involves rolling at very low temperatures in a finishing mill. Increasing the strength and thickness and / or reducing the temperature of the tapes has increased the need to open and / or unwind thicker, colder, and firmer pre-strips in a coil box.
Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Abwickelvorrichtung zum Abwickeln eines zu einem Coil aufgewickelten Bandes zu dessen Warmwalzen anzugeben. Ferner liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Verfahren zum Abwickeln eines zu einem Coil aufgewickelten Bandes zu dessen Warmwalzen anzugeben.The invention has for its object to provide an improved unwinding device for unwinding a coiled to a coil band to the hot rolling. Furthermore, the invention has the object, an improved Specify a method for unwinding a wound into a coil strip to its hot rolling.
Die Aufgabe wird erfindungsgemäß hinsichtlich der Abwickelvorrichtung durch die Merkmale des Anspruchs 1 und hinsichtlich des Verfahrens durch die Merkmale des Anspruchs 6 gelöst.The object is achieved with respect to the unwinding by the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine erfindungsgemäße Abwickelvorrichtung zum Abwickeln eines zu einem Coil aufgewickelten Bandes zu dessen Warmwalzen umfasst wenigstens zwei Bodenrollen zum unterseitigen Abstützen des Coil, einen Bandendelöser zum Ablösen eines Bandendes von dem Coil an einer Abwickelseite, und eine Niederhalterolle, die an dem Coil derart angeordnet ist, dass sie die Lage des Coil bei dem Ablösen des Bandendes stabilisiert.An unwinding apparatus for unwinding a coiled-on-coil belt for hot rolling thereof includes at least two bottom rollers for supporting the coil on the underside, a belt release for detaching a belt end from the coil at an unwinding side, and a holddown roller disposed on the coil such that it stabilizes the position of the coil when the tape end is detached.
Eine derartige Abwickelvorrichtung ermöglicht vorteilhaft, eine Lageverschiebung des Coil zu verhindern oder einzuschränken, die bei einem Ablösen des Bandendes von dem Coil entstehen kann. Derartige Lageverschiebungen des Coil bestehen insbesondere im Abheben eines Coil relativ fester, dicker und/oder kühler Bänder von den Bodenrollen bei einem Ablösen des Bandendes vom Coil, wenn der Kraftangriffspunkt außerhalb eines von den Bodenrollen unterstützten Bereiches liegt. Die Erfindung verhindert oder reduziert derartige Lageverschiebungen auf einfache und kostengünstige Weise durch eine an dem Coil angeordnete Niederhalterolle und ermöglicht so das risikolose Abwickeln von Bändern aus hochfestem Material, kühlen Bändern und dicken Bändern.Such an unwinding device advantageously makes it possible to prevent or restrict a positional shift of the coil, which may occur when the band end comes off the coil. Such positional displacements of the coil consist, in particular, in the lifting of a coil of relatively strong, thick and / or cool bands from the floor rolls when the strip end is detached from the coil when the force application point lies outside a region supported by the floor rolls. The invention prevents or reduces such positional shifts in a simple and cost-effective manner by means of a hold-down roller arranged on the coil and thus enables the risk-free unwinding of strips of high-strength material, cool strips and thick strips.
Eine Ausgestaltung der Erfindung sieht vor, dass die Niederhalterolle an einer Oberseite des Coil angeordnet ist.An embodiment of the invention provides that the hold-down roller is arranged on an upper side of the coil.
Eine alternative Ausgestaltung der Erfindung sieht vor, dass die Niederhalterolle an der Abwickelseite an dem Coil angeordnet ist.An alternative embodiment of the invention provides that the hold-down roller is arranged on the unwinding side of the coil.
Bei beiden vorgenannten Ausgestaltungen der Erfindung ist die Niederhalterolle oberhalb oder an der Abwickelseite des Coil angeordnet, so dass sie vorteilhaft Lageverschiebungen des Coil, die bei einem Ablösen des Bandendes von dem Coil entstehen können, verhindern können.In both of the aforementioned embodiments of the invention, the hold-down roller is disposed above or on the unwinding side of the coil, so that they can advantageously prevent positional shifts of the coil, which may occur in a detachment of the tape end of the coil.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Längsachsen der Niederhalterolle und der Bodenrollen parallel zueinander angeordnet sind.A further embodiment of the invention provides that the longitudinal axes of the hold-down roller and the bottom rollers are arranged parallel to each other.
Dadurch sind die Niederhalterolle und die Bodenrollen vorteilhaft zueinander gleich ausgerichtet, so dass ihre Längsachsen in derselben Richtung wie eine Wickelachse des Coil verlaufen.As a result, the hold-down roller and the bottom rollers are advantageously aligned identically to one another so that their longitudinal axes run in the same direction as a winding axis of the coil.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Niederhalterolle in einem festen Abstand zu einer Außenoberfläche des Coil angeordnet ist.A further embodiment of the invention provides that the hold-down roller is arranged at a fixed distance to an outer surface of the coil.
Dadurch wird vorteilhaft eine Lageveränderung des Coil verhindert, die den Coil über den Abstand zur Niederhalterolle hinaus verschiebt.This advantageously prevents a change in position of the coil, which shifts the coil beyond the distance to the hold-down roller.
Bei dem erfindungsgemäßen Verfahren zum Abwickeln eines zu einem Coil aufgewickelten Bandes wird der Coil unterseitig mittels wenigstens zwei Bodenrollen abgestützt, ein Bandende wird an einer Abwickelseite mittels eines Bandendelösers von dem Coil abgelöst, und eine Niederhalterolle wird an dem Coil derart angeordnet, dass die Lage des Coil bei dem Ablösen des Bandendes stabilisiert wird.In the inventive method for unwinding a coil wound into a coil, the coil is supported on the underside by means of at least two bottom rollers, a band end is detached from the coil at an unwind side by means of a band release, and a hold down roller is arranged on the coil such that the position of the coil Coil is stabilized in the detachment of the tape end.
Das Verfahren verhindert oder reduziert mit den oben bereits genannten Vorteilen Lageverschiebungen des Coil, die bei einem Ablösen des Bandendes von dem Coil entstehen können.The method prevents or reduces, with the advantages already mentioned above, positional shifts of the coil, which can occur when the strip end comes off the coil.
Ausgestaltungen des Verfahrens entsprechen den Ausgestaltungen der erfindungsgemäßen Abwickelvorrichtung mit den oben bereits genannten Vorteilen. Diese Ausgestaltungen sehen vor, dass die Niederhalterolle an einer Oberseite des Coil oder an der Abwickelseite an dem Coil angeordnet wird, und/oder dass die Längsachsen der Niederhalterolle und der Bodenrollen parallel zueinander angeordnet werden, und/oder dass die Niederhalterolle in einem festen Abstand zu einer Außenoberfläche des Coil angeordnet wird.Embodiments of the method correspond to the embodiments of the unwinding device according to the invention with the advantages already mentioned above. These embodiments provide that the hold-down roller is arranged on an upper side of the coil or on the unwinding side of the coil, and / or that the longitudinal axes of the hold-down roller and the bottom rollers are arranged parallel to each other, and / or that the hold-down roller at a fixed distance an outer surface of the coil is arranged.
