The oval caliber of one roller in a pair is at an axial gap from the round caliber of the other roller. The roller with one caliber and the other roller, in a pair, can be moved in a lateral shift (P1) in and out of the rolling line (WL).

Description

Die Erfindung bezieht sich auf ein Walzwerk zum Walzen von Draht oder Feineisen, bei dem die Walzgerüste der Vor- und Zwischenstraße, aufeinanderfolgend abwechselnd horizontale - und vertikale - Walzenpaare aufweisen. Walzwerksanlagen dieser Art (EP 0 313 930) werden durchweg mit einer Kaliberanstichfolge Oval-Rund betrieben, obgleich der Betrieb mit einer Anstichlage Oval-Oval unter anderem Vorteile bei dem Abnahme- und dem Streckungsverhalten des Walzgutstranges mit sich brächte. Der Grund für den Verzicht auf solche Vorteile ist darin zu suchen, daß die Betriebsweise mit einer Kaliberfolge Oval-Rund es erlaubt, mit der Walzenstraße Walzgutstränge unterschiedlicher Runddurchmessergrößen zu walzen, indem der Walzgutstrang innerhalb der Walzenstraße in einer mehr oder weniger großen Anzahl der vorhandenen Walzgerüste geformt wird und, nachdem die gewünschte Rundabmessung erreicht worden ist, die folgenden Walzgerüste der Straße ohne weitere Formbeeinflussung durchläuft und der Weiterverarbeitung zugeführt werden kann.The invention relates to a rolling mill for rolling wire or fine iron, in which the rolling stands of the roughing and intermediate lines, successively alternately have horizontal - and vertical - pairs of rollers. Walzwerksanlagen this type (EP 0 313 930) are consistently followed by a caliber tapping Oval-Rund operated, although the operation with an Oval-Oval tapping position below other advantages in the decrease and stretching behavior of the rolling stock would bring with it. The reason for foregoing such benefits is to look for the fact that the operation with an Oval-Rund caliber sequence allows with the rolling mill of rolled material strands of different round diameter sizes to be rolled by the rolled material strand within the roller mill in a more or less large number of existing mill stands is formed and after the desired round dimension has been reached, the following Rolling mill passes through the street without further influencing the shape and further processing can be supplied.

Der Erfindung liegt die Aufgabe zugrunde, eine Walzenstraße der gattungsgemäßen Art zu schaffen, die es erlaubt, die Vorteile der Betriebsweise mit einer Oval-Oval Kaliberfolge mit denen der Oval-Rund Anordnung der Kaliberfolge zu verbinden.The invention has for its object a roller mill of the generic type Type that allows to take advantage of operating with an oval-oval To connect the caliber sequence with those of the oval-round arrangement of the caliber sequence.

Diese Aufgabe wird dadurch gelöst, daß dem Ovalkaliber der Walzen eines Walzenpaares jeweils, mit axialem Abstand ein Rundkaliber zugeordnet wird. Dabei können die Rundkaliber dem Ovalkaliber ausgewählter Walzenpaare der Folgereihe Walzenpaare in der Walzenstraße zugeordnet werden. Innerhalb der Folgereihe der Walzenpaare können die Walzenpaare eines ersten Abschnitts jeweils nur ein Kaliber, beginnend mit einem Ovalkaliber, gefolgt abwechselnd jeweils von Ovalkalibern und Rundkalibern aufweisen. Des weiteren kann, wie die Erfindung vorsieht, daß letzte der Folgereihe der Walzenpaare der Walzenstraße nur ein Rundkaliber aufweisen. Erfindungsgemäß können weiter das eine und das andere Kaliber eines Walzenpaares durch axiale Querverschiebung der Walzen in die Walzlinie und aus dieser heraus bringbar sein, oder auch durch Querverschiebung der Walzgerüste selbst. Schließlich kann eine, dem jeweiligem Ovalkaliber eines Walzenpaares nachgeordnete, den, aus diesem austretenden Walzstrang wahlweise in das Ovalkaliber bzw. das Rundkaliber des folgenden Walzenpaares führende Lenkvorrichtung vorgesehen werden.This object is achieved in that the oval caliber of the rollers of a pair of rollers in each case, a circular caliber is assigned with an axial distance. there the round calibers can match the oval caliber of selected roller pairs in the following series Roller pairs can be assigned in the roller mill. Within the next row of the roller pairs can only the roller pairs of a first section a caliber, starting with an oval caliber, followed alternately by Have oval and round calibers. Furthermore, how the invention provides that the last of the following series of roller pairs of the roller mill only one Have round calibers. According to the invention, one and the other can continue Caliber of a pair of rollers by axially transverse displacement of the rollers in the Rolling line and be brought out of this, or by transverse displacement the rolling stands themselves. Finally, one, the respective oval caliber one Subordinate pair of rollers, optionally, from this emerging strand leading into the oval caliber or the round caliber of the following pair of rollers Steering device are provided.

Der wesentlichste, mit der Erfindung erzielbare Vorteil besteht neben der Ausnutzung der Vorteile der Anstichlagen Oval-Oval darin, daß in der so ausgebildeten Walzstraße jedem Walzgerüst der Folgereihe der Walzgerüste ein Zwischenrund für eine anschließende Fertigwalzung erzeugt werden kann. Die Oval-Oval Folge erlaubt wegen der besseren Streckung je nach den Verhältnissen in der Vor- oder Zwischenstraße, mit vergleichsweise weniger Gerüsten auszukommen. Da ggfs. jedes Gerüst der Straße neben dem Ovalkaliber ein Rundkaliber aufweist, steht vergleichsweise eine erheblich größere Zahl von Rundprofilen für die Fertigwalzung zur Verfügung. Diese kann dann ggfs. mit einer kleineren Anzahl von Fertiggerüsten durchgeführt werden.The most important advantage that can be achieved with the invention is, besides utilization of the advantages of the tapping positions oval-oval in that in the so trained Rolling mill an intermediate round for each roll stand of the following series of roll stands can be generated for a subsequent finish rolling. The oval-oval sequence allowed because of the better stretching depending on the conditions in the pre or Intermediate road to get by with comparatively fewer scaffolding. If necessary Every scaffold on the street next to the oval caliber has a round caliber comparatively a significantly larger number of round profiles for finish rolling to disposal. This can then, if necessary, with a smaller number of finishing stands be performed.

Weitere Vorteile ergeben sich daraus, daß die Rundkaliber der Walzenpaare bei der erfindungsgemäßen Anordnung weniger stark verschleißen, weil sie nur zur Erzeugung der jeweils benötigten Größe eines Rundprofils beansprucht werden.Further advantages result from the fact that the round calibers of the roller pairs contribute the arrangement according to the invention wear less because they are only for Generation of the required size of a round profile can be claimed.

Schließlich kann die Gesamtzahl der Walzgerüste einer Walzenstraße sowohl gerade als auch ungerade gewählt werden, während diese Zahl bei der bekannten Oval-Rundkaliberfolge stets eine gerade Zahl sein muß. Finally, the total number of mill stands on a roll mill can be both straight can be chosen as odd, while this number in the known Oval round caliber sequences must always be an even number.

WSQ der Walzenstraße WS I. zugeführt, deren, nicht dargestellte Walzgerüste eine Wechselfolge von Horizontal- und Vertikal-Walzenpaaren 1. H, 2. V, 3. H, 4. V, 5. H, 6. V, 7. H, 8. V aufweisen. Von diesen Walzenpaaren sind die Horizontalwalzenpaare 1. H, 3. H, 5. H, 7. H jeweils mit einem Ovalkaliber und die Vertikalwalzenpaare 2. V, 4. V, 6. V, 8. V jeweils mit einem Rundkaliber ausgestattet.As can be seen from FIG. 1, pre-profiled rolling stock strands WSR or WSQ of the roller mill WS I. fed, the roll stands, not shown an alternation of horizontal and vertical roller pairs 1. H, 2. V, 3. H, 4. V, 5. H, 6. V, 7. H, 8. V have. Of these roller pairs, the horizontal roller pairs are 1st H, 3rd H, 5th H, 7th H each with an oval caliber and the vertical roller pairs 2nd V, 4th V, 6th V, 8th V each equipped with a round caliber.

Das Rund- bzw. Quadratprofil WSR bzw. WSQ des, in das erste Horizontalwalzenpaar 1. H eingeführten Walzgutstrangs und darin zu einem Oval geformt, wird in den folgenden Walzenpaaren abwechselnd jeweils zu einem Rund und wieder zu einem Oval geformt und verläßt die Walzenstraße, vom Vertikalwalzenpaar 8. V geformt als, für die Fertigwalzung bestimmter Rundstab. Diese Kaliberanordnung der Walzenstraße WS I. erlaubt es, den Rundstab je nach den gewünschten Abmaßen jeweils, immer nach seinem Durchgang durch eines der Vertikalwalzenpaare 2. V bis 8. V bei Leerdurchgang durch die anschließenden Walzenpaare aus der Walzenstraße auszubringen und der Weiterverarbeitung zuzuführen. The round or square profile WSR or WSQ in the first pair of horizontal rolls 1. H is inserted and rolled into an oval, is rolled in the following pairs of rolls alternately to a round and again formed into an oval and leaves the roller mill, from the pair of vertical rollers 8. V shaped as round bar intended for finish rolling. This caliber arrangement The roller mill WS I. allows the round bar to be selected according to the desired Dimensions, always after passing through one of the vertical roller pairs 2. V to 8. V when passing through the subsequent pairs of rollers when empty to be discharged from the roller mill and sent for further processing.

Aus Figur 2 geht hervor, daß der vorprofilierte Walzgutstrang WSR bzw. WSQ einer Walzenstraße WS 11. zugeführt wird, deren, nicht dargestellte Walzgerüste eine Folge von Horizontal- und Vertikalwalzenpaaren 1. H, 2. V, 3. H, 4. V, 5. H, 6. V, 7. H, 8. V aufweisen. Diese Walzenpaare sind, bis auf das erste und letzte Walzenpaar 1. H. und 8. V sämtlich mit horizontal bzw. vertikal liegenden Ovalkalibern und, axial versetzt neben diesen angeordneten Rundkalibern ausgestattet. Das letzte der Walzenpaare weist hinter dieser Folge von Ovalkalibern ein Rundkaliber auf. Die, mit diesen beiden nebeneinander liegenden Kalibern ausgestatteten, nicht dargestellten Walzenpaare 2. V, 3. H, 4. V, 5. H, 6. V, und 7. H lassen sich auf nicht dargestellte Weise in Richtung des Doppelpfeils P1 quer zu der mit einem Pfeil WL angedeuteten Walzlinie in diese hinein und aus dieser heraus verschieben. Statt dessen können auch in Richtung dieser Walzlinie WL jeweils hinter den Ovalkalibem nicht dargestellte, mit Schrägpfeilen angedeutete Leitvorrichtungen angeordnet werden, die den aus diesen Kalibern austretenden Anfang des Walzgutstrangs in das, neben dem folgenden Ovalkaliber liegende Rundkaliber lenken.It can be seen from FIG. 2 that the pre-profiled strand WSR or WSQ is one Rolling mill WS 11 is supplied, the roll stands, not shown, a Sequence of horizontal and vertical roller pairs 1st H, 2nd V, 3rd H, 4th V, 5th H, 6th V, 7th H, 8th V. These roller pairs are, except for the first and last Pair of rollers 1st H. and 8th V all with horizontal or vertical oval calibres and, axially offset next to these arranged round calibers. The last of the roller pairs has a round caliber behind this series of oval calibers on. The equipped with these two calibers lying side by side, roller pairs, not shown, 2nd V, 3rd H, 4th V, 5th H, 6th V, and 7th leave in a direction not shown in the direction of the double arrow P1 transverse to the an arrow WL indicated rolling line in and out of this. Instead, WL can also move in the direction of this rolling line the oval caliber not shown, indicated with oblique arrows be arranged, which the emerging from these calibres of the Rolled stock into the round caliber next to the following oval caliber to steer.

Anders als bei der Anordnung nach Figur 1, bei der der Rundstab nur nach einem Durchgang durch eines der Rundkaliber der Kaliberfolge aus dem Formprozeß herausgenommen und den Weiterverarbeitungsvorrichtungen zugeführt werden kann, ist es hier möglich den Walzstab hinter jedem der Ovalkaliber in einen Rundstab zu formen und den Weiterverarbeitungseinrichtungen zuzuführen.In contrast to the arrangement according to FIG. 1, in which the round bar only after one Passage through one of the round calibers of the caliber sequence from the molding process removed and fed to the further processing devices can, it is possible to put the rolling rod behind each of the oval calibers in one To shape the round bar and feed it to the processing facilities.

Die Anordnung nach Figur 3 unterscheidet sich von der nach Figur 2 dadurch, daß die ersten Walzenpaare der Walzenstraße WS III. der Anordnung nach Figur 1 entsprechend und die anschließenden Walzenpaare der Folge der Anordnung nach Figur 2. The arrangement of Figure 3 differs from that of Figure 2 in that the first roller pairs of the roller mill WS III. the arrangement of Figure 1 accordingly and the subsequent roller pairs of the sequence of the arrangement according to FIG. 2.
