An independent claim is also included for a wire rolling mill with a finishing stand for rolling a wire.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Draht, bei dem der Draht in mindestens einem Fertiggerüst eines Drahtwalzwerks gewalzt wird, wobei der gewalzte Draht hinter dem in Förderrichtung letzten Fertiggerüst eine Kühl- und/oder Ausgleichsstrecke passiert, wobei der Draht durch einen am Ende der Kühlund/oder Ausgleichsstrecke angeordneten ersten Treiber durch die Kühl- und/oder Ausgleichsstrecke gezogen wird und wobei in Förderrichtung hinter dem ersten Treiber ein Windungsleger für den Draht angeordnet ist, mit dem er in Windungen abgelegt werden kann. Des weiteren betrifft die Erfindung ein Drahtwalzwerk zur Durchführung des Verfahrens.The invention relates to a method for producing wire, in which the wire is rolled in at least one finishing stand of a wire rolling mill, wherein the rolled wire passes behind the final finishing stand in the conveying direction a cooling and / or compensation path, wherein the wire by a at the end of Cooling and / or balancing path arranged first driver is pulled through the cooling and / or balancing section and wherein in the conveying direction behind the first driver a Windungsleger for the wire is arranged, with which it can be stored in turns. Furthermore, the invention relates to a wire rolling mill for carrying out the method.

Beim Walzen von Draht wird der Draht in einem letzten Walzprozess in einem Fertigblock von einer Anzahl Fertiggerüsten gewalzt und auf den endgültigen gewünschten Drahtdurchmesser gebracht. Anschließend durchläuft der Draht eine Kühl- und Ausgleichsstrecke, bevor er mittels eines Windungslegers in Windungen abgelegt wird.In wire rolling, in a final rolling process, the wire is rolled in a finishing block from a number of finishing stands and brought to the final desired wire diameter. The wire then passes through a cooling and equalizing section before being laid in turns by means of a layer.

Derartige Lösungen gemäß dem Stand der Technik sind für zwei mögliche Ausgestaltungen in den Figuren 1 und 2 gezeigt. Dargestellt ist ein Teil eines Drahtwalzwerks 3, von dem insbesondere ein Fertigblock mit einer Anzahl Fertiggerüsten 2 zu sehen ist. Der Draht 1 wird in den Fertiggerüsten 2 abschließend gewalzt.Such solutions according to the prior art are for two possible embodiments in the Figures 1 and 2 shown. Shown is a part of a wire rolling mill 3, of which in particular a finished block with a number finishing stands 2 can be seen. The wire 1 is finally rolled in the finishing stands 2.

Er verlässt den Fertigblock in Förderrichtung F mit einer Geschwindigkeit VD. Hinter dem Fertigblock gelangt der Draht 1 in eine Kühl- und Ausgleichsstrecke 4. Gemäß Fig. 1 ist hinter der Kühl- und Ausgleichsstrecke 4 ein Treiber 5 angeordnet, der den Draht 1 durch die Kühl- und Ausgleichsstrecke 4 zieht. Unmittelbar hinter dem Treiber 5 ist ein Windungsleger 6 angeordnet, der den Draht 1 in bekannter Weise in Windungen ablegt.He leaves the finished block in the conveying direction F at a speed V D. Behind the finished block, the wire 1 enters a cooling and equalizing section 4. According to Fig. 1 behind the cooling and balancing section 4, a driver 5 is arranged, which pulls the wire 1 through the cooling and balancing section 4. Immediately behind the driver 5 a Windungsleger 6 is arranged, which deposits the wire 1 in a known manner in turns.

Die Lösung gemäß Fig. 2 unterscheidet sich von derjenigen nach Fig. 1 im wesentlichen nur dadurch, dass hier noch innerhalb der Kühl- und Ausgleichsstrecke 4 ein weiterer Treiber 5 angeordnet ist, der den Draht 1 bei seinem Passieren der Kühl- und Ausgleichsstrecke 4 unter Zug hält.The solution according to Fig. 2 differs from the one after Fig. 1 essentially only in that a further driver 5 is arranged here within the cooling and equalizing section 4, which keeps the wire 1 under tension as it passes the cooling and equalizing section 4.

Dargestellt ist in beiden Figuren, dass aufgrund der Konzeption der Anlage der Draht 1 auch im Bereich des Treibers 5 und des Windungslegers 6 die Geschwindigkeit VD hat, mit der der Draht 1 den Fertigblock verlässt.It is shown in both figures that due to the design of the system, the wire 1 in the area of the driver 5 and the winding layer 6 has the speed V D , with the wire 1 leaves the finished block.

Der Draht 1 verlässt somit den Fertigblock bzw. dessen Fertiggerüste 2 mit der Geschwindigkeit VD, die allerdings nicht absolut konstant ist. Vielmehr schwankt die Geschwindigkeit VD um einen Mittelwert. Diese Geschwindigkeitsschwankung führt dazu, dass das Legebild des Drahtes nicht optimal ist, d. h. der Windungsdurchmesser des vom Windungsleger abgelegten Drahtes 1 ist nicht konstant, da der Windungsleger mit konstanter Drehzahl rotiert, der Draht beim Eintritt in den Windungsleger jedoch eine nicht-konstante Geschwindigkeit aufweist.The wire 1 thus leaves the finished block or its finishing stands 2 at the speed V D , which, however, is not absolutely constant. Rather, the speed V D fluctuates around an average value. This variation in speed results in that the shed shape of the wire is not optimal, that is, the winding diameter of the wire 1 laid down by the layer is not constant, since the layer rotates at a constant speed, but the wire has a non-constant speed when entering the layer.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren sowie ein zugehöriges Drahtwalzwerk zu schaffen, mit denen es möglich ist, ein verbessertes Legebild des vom Windungsleger abgelegten Drahtes zu erreichen, insbesondere den Draht mit einem möglichst konstanten Windungsdurchmesser abzulegen.The invention is therefore based on the object to provide a method and an associated wire rolling mill, with which it is possible to achieve an improved shingling of the laid wire from the layer, in particular to deposit the wire with a very constant winding diameter.

Diese Aufgabe wird durch die Erfindung verfahrensgemäß dadurch gekennzeichnet, dass ein in Förderrichtung hinter dem ersten Treiber und vor dem Windungsleger angeordneter zweite Treiber so betrieben wird, dass der Draht zwischen den beiden Treibern eine Schlinge mit einer von der geraden Solllinie aus gemessenen Schlingenhöhe bildet.This object is achieved by the invention according to the method characterized in that in the conveying direction behind the first driver and before the Windungsleger arranged second driver is operated so that the wire between the two drivers forms a loop with a measured from the straight nominal line loop height.

Der Antrieb des zweiten Treibers kann dabei so geregelt werden, dass die Schlingenhöhe innerhalb eines vorgegebenen Wertebereichs liegt.The drive of the second driver can be controlled so that the loop height is within a predetermined range of values.

Vorzugsweise wird weiterhin die Antriebsgeschwindigkeit des Windungslegers in Abhängigkeit der Fördergeschwindigkeit des zweiten Treibers gesteuert oder geregelt.Preferably, the drive speed of the Windungslegers is further controlled or regulated in dependence on the conveying speed of the second driver.

Der Draht wird in der Kühl- und/oder Ausgleichsstrecke zwischen dem letzten Fertiggerüst und dem ersten Treiber von diesem vorzugsweise unter einem vorgegebenen Zug gehalten. Weiterhin kann vorgesehen sein, dass innerhalb der Kühlund/oder Ausgleichsstrecke ein weiterer Treiber angeordnet ist, der auf den Draht eine Zugkraft ausübt.The wire is held in the cooling and / or compensation path between the last finishing stand and the first driver of this preferably under a predetermined train. Furthermore, it can be provided that within the cooling and / or compensation path, a further driver is arranged, which exerts a tensile force on the wire.

Das vorgeschlagene Drahtwalzwerk zeichnet sich erfindungsgemäß dadurch aus, dass in Förderrichtung hinter dem ersten Treiber und vor dem Windungsleger ein zweiter Treiber angeordnet ist, der so antreibbar ist, dass der Draht zwischen den beiden Treibern eine Schlinge mit einer von der geraden Solllinie aus gemessenen Schlingenhöhe bildet.The proposed wire rolling mill is characterized according to the invention in that in the conveying direction behind the first driver and before the Windungsleger a second driver is arranged, which is driven so that the wire between the two drivers forms a loop with a measured from the straight nominal line loop height ,

Dabei sind zur Regelung der Größe der Schlinge bevorzugt Messmittel zur Erfassung der Schlingenhöhe der Schlinge vorgesehen. Ferner sind mit Vorteil Regelmittel vorhanden, die mit dem Messmittel in Verbindung stehen und einen Antriebsmotor für den zweiten Treiber beeinflussen können.In this case, to control the size of the loop preferably measuring means for detecting the loop height of the loop are provided. Furthermore, control means are advantageously present which are connected to the measuring means and can influence a drive motor for the second driver.

Die Regelmittel können auch einen Antriebsmotor des Windungslegers beeinflussen, so dass auf diese Weise eine Synchronisation der Arbeitsgeschwindigkeit des zweiten Treibers und des Windungslegers vorgenommen werden kann.The control means can also influence a drive motor of the layer, so that in this way a synchronization of the operating speed of the second driver and the Windungslegers can be made.

Mit dem erfindungsgemäßen Vorschlag wird erreicht, dass mit relativ einfachen Mitteln sichergestellt werden kann, dass der Draht vom Windungsleger mit konstantem Durchmesser abgelegt werden kann. Schwankungen in der Drahtgeschwindigkeit, die hinter dem Fertigblock vorliegen, können in einfacher Weise ausgeglichen werden.With the proposal according to the invention it is achieved that it can be ensured with relatively simple means that the wire can be stored by the layer with a constant diameter. Variations in the wire speed, which are present behind the finished block, can be compensated in a simple manner.

Der Walzprozess ist damit vom Legeprozess entkoppelt.The rolling process is thus decoupled from the laying process.

In vorteilhafter Weise ergeben sich bessere Drahtbunde, geringere Probleme mit Abweichungen der Durchmesser der Windungen und weniger Stillstände der Anlage.Advantageously, there are better wire coils, fewer problems with deviations in the diameter of the turns and less downtime of the system.

In Fig. 3 ist ein Ausschnitt aus einem Drahtwalzwerk 3 zu sehen, das analog zu der eingangs beschriebenen Lösung gemäß dem Stand der Technik aufgebaut ist (s. Fig. 1 und 2). Der Draht 1 verlässt in Förderrichtung F die Fertiggerüste 2 eines Fertigblocks, um in eine Kühl- und Ausgleichsstrecke 4 zu gelangen. Der Draht 1 wird durch die Kühl- und Ausgleichsstrecke 4 mittels eines ersten Treibers 5 gezogen; der Treiber 5 hält den Draht 1 beim Passieren der Kühl- und Ausgleichsstrecke 4 unter Zug. Die Treibgeschwindigkeit des ersten Treibers 5 bestimmt sich nach der Drahtgeschwindigkeit VD des Drahts 1 hinter dem Fertigblock. Dort hat der Draht 1 die Geschwindigkeit VD, die nicht konstant ist, sondern um einen Mittelwert schwankt. Hinter der Kühl- und Ausgleichsstrecke 4 gelangt der Draht 1 in einen Windungsleger 6, der ihn in bekannter Weise in Windungen ablegt, z. B. auf ein Förderband.In Fig. 3 is a section of a wire rolling mill 3 to see, which is constructed analogously to the solution described above according to the prior art (s. Fig. 1 and 2 ). The wire 1 leaves in the conveying direction F the finishing stands 2 of a finished block in order to reach a cooling and equalizing section 4. The wire 1 is pulled by the cooling and equalizing section 4 by means of a first driver 5; the driver 5 holds the wire 1 when passing the cooling and balancing section 4 under train. The driving speed of the first driver 5 is determined by the wire speed V D of the wire 1 behind the finished block. There, the wire 1 has the velocity V D , which is not constant, but fluctuates around an average value. Behind the cooling and equalizing section 4 of the wire 1 enters a Windungsleger 6, which deposits it in a known manner in turns, z. B. on a conveyor belt.

Wesentlich ist, dass in Förderrichtung F hinter dem ersten Treiber 5 und vor dem Windungsleger 6 ein zweiter Treiber 7 angeordnet ist. Die beiden Treiber 5 und 7 sind voneinander beabstandet. Der zweite Treiber 7 wird dabei gezielt so betrieben, dass der Draht 1 zwischen den beiden Treibern 5 und 7 eine Schlinge 8 bildet. Wie in Fig. 3 zu sehen ist, hat die Schlinge 8 eine Schlingenhöhe H, die von der geraden Solllinie oder Ideallinie 9 aus gemessenen wird.It is essential that in the conveying direction F behind the first driver 5 and before the Windungsleger 6, a second driver 7 is arranged. The two drivers 5 and 7 are spaced apart. The second driver 7 is selectively operated so that the wire 1 between the two drivers 5 and 7 forms a loop 8. As in Fig. 3 can be seen, the loop 8 has a loop height H, which is measured from the straight line or ideal line 9 from.

Der zweite Treiber 7 fördert den Draht 1 mit einer Geschwindigkeit VT, die weitgehend konstant gehalten wird und aufgrund deren sich der Windungsdurchmesser des Drahts ergibt, wenn er vom Windungsleger 6 abgelegt wird. Der zweite Treiber 7 wird nämlich mit einer konstanten Geschwindigkeit VT betrieben, wobei die Antriebsgeschwindigkeit des Windungslegers 6 an die Antriebsgeschwindigkeit des zweiten Treibers 7 gekoppelt ist.The second driver 7 conveys the wire 1 at a speed V T , which is kept substantially constant and on account of which the winding diameter of the wire results when it is laid down by the layer 6. Namely, the second driver 7 is operated at a constant speed V T , wherein the drive speed of the coil former 6 is coupled to the drive speed of the second driver 7.

Schwankungen in der Geschwindigkeit VD können auf diese Weise mittels der Schlinge 8 ausgeglichen werden, und die Zufuhr des Drahts 1 in den Windungsleger 6 erfolgt mittels des zweiten Treibers 7 mit konstanter Geschwindigkeit VT. Dies führt zu einem optimalen Legebild, da der Windungsdurchmesser konstant ist.Variations in the speed V D can be compensated in this way by means of the sling 8, and the supply of the wire 1 in the layers 6 takes place by means of the second driver 7 at a constant speed V T. This leads to an optimal shed image, since the winding diameter is constant.

Details hierzu sind in Fig. 4 dargestellt. Wie gezeigt, wird der Draht 1 - um Geschwindigkeitsschwankungen in der Drahtgeschwindigkeit am Auslauf aus dem Fertigblock ausgleichen zu können - zwischen den beiden Treibern 5 und 7 nicht linear entlang der Solllinie 9 geführt, sondern bogenförmig, so dass die Schlinge 8 ausgebildet wird. Im Scheitelpunkt hat die Schlinge 8 eine Schlingenhöhe H, die sich zwischen einem vorgebbaren Minimalwert Hmin und einem Maximalwert Hmax bewegen darf. Die jeweiligen Verläufe des Drahts 1 sind mit gestrichelten Linien dargestellt.Details are in Fig. 4 shown. As shown, in order to be able to compensate for speed variations in the wire speed at the outlet from the finished block, the wire 1 is not guided linearly along the nominal line 9 between the two drivers 5 and 7, but curved, so that the loop 8 is formed. At the apex, the loop 8 has a loop height H, which may move between a predeterminable minimum value H min and a maximum value H max . The respective courses of the wire 1 are shown with dashed lines.

Der aktuelle Wert der Schlingenhöhe H wird mittels eines Messmittels 10 ermittelt, bei dem es sich z. B. um eine Lichtschranke handeln kann, die die maximale Auslenkung des Drahts 1 von der Solllinie 9 messen kann. Der von dem Messmittel 10 ermittelte Wert für die Schlingenhöhe H wird einem Regelmittel 11 zugeführt.The current value of the loop height H is determined by means of a measuring means 10, in which it is z. B. can act to a light barrier, which can measure the maximum deflection of the wire 1 from the target line 9. The value determined by the measuring means 10 for the loop height H is fed to a control means 11.

Die Regelmittel 11 steuern einen Antriebsmotor 12 für den zweiten Treiber 7 so an, dass die Schlingenhöhe H innerhalb des zulässigen Bereichs liegt. Wird der Wert für die Schlingenhöhe zu groß, wird der Antriebsmotor 12 zu einem schnelleren Drehen veranlasst, wird der Wert zu klein, wird der Antriebsmotor 12 langsamer. Die Schlingenhöhe H wird also im geschlossenen Regelkreis auf einem gewünschten Wert gehalten.The control means 11 drive a drive motor 12 for the second driver 7 so that the loop height H is within the allowable range. If the value of the loop height becomes too large, the drive motor 12 is caused to rotate faster, and if the value becomes too small, the drive motor 12 becomes slower. The loop height H is thus kept in the closed loop at a desired value.

Wie in Fig. 4 nur schematisch angedeutet ist, kann das Regelmittel 11 auch entsprechend auf den Antrieb des Windungslegers 6 Einfluss nehmen, so dass die Arbeitsgeschwindigkeiten des zweiten Treibers 7 und die des Windungslegers 6 synchronisiert sind. Das Ergebnis sind gelegte Windungen mit einheitlichen Windungsdurchmesser.As in Fig. 4 is indicated only schematically, the control means 11 can also take corresponding effect on the drive of the Windungslegers 6, so that the operating speeds of the second driver 7 and that of the Windungslegers 6 are synchronized. The result is laid turns with uniform winding diameter.
