Description

Die Erfindung betrifft eine Walzenstraße zum Walzen von Draht und Feineisen mit einer Vor- und Zwischenstraße, in der der Walzgutstrang eine Mehrzahl von Walzgerüsten durchläuft, von denen, aufeinander folgend, abwechselnd das eine ein Horizontalwalzenpaar und das folgende ein Vertikalwalzenpaar aufweist.The invention relates to a rolling mill for rolling wire and fine iron a roughing and intermediate line in which the rolled material strand has a plurality of Passes through rolling stands, of which one after the other takes turns one pair of horizontal rolls and the following one pair of vertical rolls.

In den Vor- und Zwischenstraßen wird das in Strang- oder Knüppelform heran geführte Walzgut in einer mehr oder weniger großen Anzahl der mit Abstand voneinander angeordneten Walzgerüste in deren Horizontal- bzw. Vertikalwalzenpaaren mit verhältnismäßig großen Querschnittsabnahmen pro Gerüst auf einen Querschnitt gewalzt, dessen Abmaße um ein geringes Maß über dem des zu walzenden Fertigquerschnitts liegen.In the main and intermediate streets this is approaching in the form of a strand or a stick guided rolling stock in a more or less large number of spaced from each other arranged roll stands in their horizontal or vertical roll pairs with relatively large cross-sectional decreases per scaffolding on one Rolled cross-section, the dimensions of which are slightly larger than that of the rolled Finished cross-section.

Der Walzgutstrang mit dem so gewalzten Querschnitt wird anschließend in die Walzgerüstreihe einer Fertig- bzw. Maßwalzstraße eingebracht, deren Kaliber den Querschnitt des Walzgutstranges mit verhältnismäßig kleinen Abnahmeschritten und Korrekturen (Sizing) auf die Fertigabmessung bringen.The strand of rolled material with the cross section rolled in this way is then fed into the Rolling mill row introduced a finishing or sizing mill, whose caliber the Cross-section of the rolling stock with relatively small decrease steps and bring corrections (sizing) to the final dimensions.

Die in der Vor- bzw. Zwischenstraße angeordneten Walzgerüste benötigen jeweils einen eigenen Antrieb, und zwischen den einzelnen Gerüsten sind für den durchlaufenden Walzgutstrang durchweg Führungsvorrichtungen oder stützende Rollgangsabschnitte notwendig. Diese Straßen bringen neben dem großen Bauaufwand einen erheblichen Platzbedarf mit sich und erfordern beim Betrieb einen entsprechend großen Bedienungs- und Wartungsaufwand. The rolling stands arranged in the roughing or intermediate line each require own drive, and between the individual scaffolds are for the continuous Roll of rolled material consistently of guide devices or supporting roller table sections necessary. In addition to the large construction costs, these roads bring take up a lot of space and require one during operation correspondingly large operating and maintenance costs.

Der Erfindung liegt die Aufgabe zugrunde, sowohl die Zahl der in dieser Vor- bzw. Zwischenstraße erforderlichen Walzgerüste und den damit verbundenen Platzbedarf, als auch den übrigen Aufwand erheblich zu verringern.The invention is based on the object, both the number in this preliminary or Intermediate mill required roll stands and the associated space requirement, as well as significantly reduce the remaining effort.

Ausgehend von aus EP 0 768 124 A2 und 0 549 896 A1 bekannten Vorschlägen für die Formung insbesondere des Rundquerschnittumfangs von aus der Zwischenstraße austretenden Walzgutsträngen in die Walzgerüste der anschließenden Fertigstraße ein oder zwei der ersten Gerüste dieser Fertigstraße mit je einem Horizontalwalzen- und einem dicht hinter diesem angeordneten Vertikalwalzenpaar auszustatten, wobei die Walzenpaare in Walzrichtung gegeneinander abstandsverstellbar ausgebildet wurden, um durch Veränderung des Abstandes der Drehneigung des Walzgutstranges zwischen den Walzenpaaren entgegen zu wirken, schlägt die Erfindung vor, anstelle der jeweils ein Horizontal- bzw. ein Vertikalwalzenpaar aufweisenden Walzgerüste in der Vor- bzw. Zwischenstraße je ein Horizontalwalzenpaar und ein Vertikalwalzenpaar in einem gemeinsamen Walzgerüst anzuordnen, wobei die Walzenpaare mit ihren vertikalen Achsebenen in Walzrichtung verschieb- und festlegbar angeordnet sind und das Horizontalwalzenpaar mit einem Walzenantrieb verbunden ist.Based on proposals known from EP 0 768 124 A2 and 0 549 896 A1 for the shaping, in particular, of the circular cross-section circumference from the intermediate street emerging strands of rolling stock in the rolling stands of the subsequent Finishing line one or two of the first stands of this finishing line, each with one Horizontal rollers and a pair of vertical rollers arranged closely behind this equip, the pairs of rollers adjustable in distance from each other in the rolling direction were trained to change the distance of the Counteracting the inclination of the strand of rolled material between the pairs of rollers, proposes the invention, instead of a horizontal and a vertical pair of rollers rolling stands in the roughing or intermediate line A pair of horizontal rolls and a pair of vertical rolls in a common roll stand to arrange, the roller pairs with their vertical axis planes in the rolling direction are arranged displaceable and lockable and the pair of horizontal rollers is connected to a roller drive.

Für die erfindungsgemäß so ausgestattete Zwischenstraße wird praktisch nur die halbe Anzahl der für die bisherige Ausbildung erforderlichen Walzgerüste benötigt; dasselbe gilt auch für die Zahl der Antriebsaggregate. Außer dem entsprechend verringerten Platzbedarf der erfindungsgemäßen Anordnung werden auch weniger Führungseinrichtungen zwischen den Walzgerüsten benötigt.For the intermediate street thus equipped according to the invention, practically only the half the number of roll stands required for the previous training required; the same also applies to the number of drive units. Except for that reduced space requirements of the arrangement according to the invention are also less Guide devices between the roll stands required.
