Abstract
Description
Die Erfindung bezieht sich auf eine kontinuierliche Feinstahl- oder Drahtstraße, umfassend, hinter dem Zwischenwalzabschnitt der Straße angeordnete Fertigwalz- und Maßwalzeinheiten, vor, zwischen und hinter diesen angeordnete Kühlstrecken und Temperaturausgleichsstrecken sowie, diesen nachgeordnete Walzgutsammeleinrichtungen.The invention relates to a continuous fine steel or Wire mill, comprising, behind the intermediate rolling section of the road arranged finish rolling and sizing units, before, between and cooling sections and temperature compensation sections arranged behind them as well as these subordinate rolling stock collection facilities.
Drahtstraßen dieser Bauart stellen die anlagetechnische Voraussetzung für ein temperaturkontrolliertes Walzen dar, mit dem die mechanischen Eigenschaften des Walzgutes verbessert (thermomechanisches Walzen), dem Walzprozess nachgeschaltete Wärmebehandlungsprozesse eingespart und kontrollierte Temperaturprofile innerhalb der Walzlinie eingestellt werden können.Wire lines of this type are the technical prerequisite for a temperature-controlled rolling with which the mechanical properties of the rolling stock improved (thermomechanical Rolling), the heat treatment processes downstream of the rolling process saved and controlled temperature profiles within the rolling line can be adjusted.
Dieses thermomechanische Walzen stellt wegen der hohen Endwalzgeschwindigkeit beim Fertigwalzen in den Block-Fertigwalzeinheiten mit kurzen Gerüstabständen und der Aufheizung des Walzgutes beim Walzen besonders hohe Anforderungen an die Temperaturführung, die in der Regel eine Temperaturabsenkung auf bestimmte Werte bereits vor dem Fertigwalzen erfordert.This thermomechanical rolling poses because of the high final rolling speed during finish rolling in the block finish rolling units with short stand spacing and the heating of the rolling stock at Roll particularly high demands on the temperature control, the usually a temperature reduction to certain values already required before finish rolling.
Bei einer bekannten Walzstraße (Stahl und Eisen 108, Seiten 75 - 80) wird hinter dem letzten Gerüst der Zwischenstraße in einer gradlinigen Walzlinie innerhalb einer verhältnismäßig langen Temperaturausgleichsstrecke, vor der Fertigwalzeinheit, etwa mittig eine Kühlstrecke vorgesehen, hinter dieser Fertigwalzeinheit eine weitere Kühlstrecke, dann eine Maßwalzeinheit, an die sich bis zur Walzgutsammeleinrichtung mehrere hintereinander angeordnete Kühlstrecken anschließen.In a known rolling mill (Stahl und Eisen 108, pages 75 - 80) behind the last scaffolding of the intermediate street in one straight rolling line within a relatively long temperature compensation section, in front of the finishing roller unit, approximately one in the middle Cooling section provided, behind this finishing roller unit another Cooling section, then a sizing unit, to which up to the rolling stock collecting device several cooling sections arranged one behind the other connect.
Diese Ausbildungsform erlaubt zwar die Einhaltung, Modifizierung und Kontrolle des gewünschten Temperaturprofils, erfordert aber wegen der langen Temperaturausgleichsstrecken und der übrigen Kühlstrecken sehr viel Raum.This form of training allows compliance, modification and control of the desired temperature profile, but requires because of the long temperature compensation distances and the rest Cooling sections take up a lot of space.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße kontinuierliche Feinstahl- oder Drahtstraße zu schaffen, die ein temperaturkontrolliertes Walzen unter erheblich geringerem Raumbedarf, ausgehend von einer bekannten Ausbildung einer solchen Walzstraße (EP 0 571 789 A1), bei der zwischen dem Pilot-Gerüst und der Zwischengerüstgruppe eine erste Ausgleichsstrecke mit einer, durch einen ersten horizontalen Schlingenbildner geführten 180°-Schlinge des Walzgutes und zwischen der Zwischengerüst- und der Fertiggerüstgruppe eine zweite Ausgleichsstrecke mit einer, durch einen zweiten horizontalen Schlingenbildner geführten 180°-Schlinge des Walzgutes angeordnet ist, wird diese Aufgabe dadurch gelöst, daß die Fertigwalzeinheit zwei, selbständige Fertigwalzeinheiten aufweist, von denen die eine Fertigwalzeinheit in einer, hinter dem Zwischenwalzabschnitt über eine Weiche von einer zweiten Walzlinie abgezweigten, ersten Walzlinie angeordnet ist, die hinter dieser eine horizontale Umführung und eine, zwischen dieser, an der Fertigwalzeinheit vorbeiverlaufende Temperaturausgleichsstrecke mit Kühlstrecke sowie eine weitere, an diese anschließende Umführung aufweist, dem eine, vor der ersten Fertigwalzeinheit in die zweite Walzlinie führende Weiche nachgeordnet ist, und daß die andere Fertigwalzeinheit in der, parallel zu dieser ersten Walzlinie verlaufenden zweiten Walzlinie angeordnet ist. Dabei können, wie die Erfindung weiter vorschlägt, in der zweiten Walzlinie, hinter der Weiche und vor der Fertigwalzeinheit und der Maßwalzeinheit eine, und hinter diesen, zwei Kühlstrecken angeordnet werden. Weiter können in der ersten Walzlinie, unmittelbar hinter der Fertigwalzeinheit und vor der ersten Umführung je eine und hinter dieser, vor einer Temperaturausgleichsstrecke, eine weitere Kühlstrecke angeordnet werden. Es empfiehlt sich auch, in den beiden Walzlinien jeweils, unmittelbar vor der jeweiligen Fertigwalzeinheit Scheren anzuordnen.The invention has for its object a generic continuous fine steel or wire mill to create the one temperature-controlled rolling in a significantly smaller space, based on a known design of such a rolling mill (EP 0 571 789 A1), in which between the pilot scaffold and the Intermediate scaffolding group with a first compensation section a first horizontal loop-forming 180 ° loop of the rolling stock and between the intermediate stand and the finishing stand group a second compensation line with one, through a second horizontal loop-formers guided 180 ° loop of the rolled stock is arranged, this object is achieved in that the finish rolling unit has two independent finishing units, from which the one finishing roll unit in one, behind the intermediate rolling section branched off from a second rolling line via a switch, first rolling line is arranged behind this a horizontal Bypass and one, between this, on the finishing roller unit passing temperature compensation section with cooling section as well has a further bypass following this, the one, leading into the second rolling line before the first finishing roller unit Switch is downstream, and that the other finishing roller unit in the second, parallel to this first rolling line Rolling line is arranged. Here, how the invention continues proposes in the second rolling line, behind the switch and in front of the Finish rolling unit and the sizing unit one, and behind these, two cooling lines can be arranged. Can continue in the first Rolling line, immediately behind the finishing roll unit and in front of the first bypass one and behind it, in front of a temperature compensation section, another cooling section can be arranged. It is also recommended, in each of the two rolling lines, immediately Arrange scissors in front of the respective finishing unit.
Die so ausgebildete Drahtstraße kann, wie die Erfindung vorschlägt, so betrieben werden, daß der aus dem Zwischenwalzabschnitt kommende Walzdrahtstrang zunächst über die Weiche in die erste Walzlinie und dort in die Fertigwalzeinheit eingebracht, über die Umführungen und die Weiche in die zweite Walzlinie geführt und in der Fertigwalzeinheit und Maßwalzeinheit fertiggewalzt wird. Der aus dem Zwischenwalzabschnitt kommende Walzdrahtstrang kann aber auch entweder im geradlinigen Durchlauf in die zweite Walzlinie eingebracht und in der Fertigwalzeinheit und Maßwalzeinheit oder über die Weiche in die erste Walzlinie eingebracht, dort in der Fertigwalzeinheit querschnittsverringert, anschließend über die Umführungen und die Weiche in die zweite Walzlinie geführt, nach Leerdurchgang durch die Fertigwalzeinheit in der Maßwalzeinheit fertiggewalzt werden.The wire mill thus formed can, as the invention proposes, be operated so that the coming from the intermediate rolling section Wire rod initially over the switch in the first rolling line and introduced into the finishing roll unit there, via the bypasses and the switch is guided into the second rolling line and in the finishing roller unit and sizing unit is finish-rolled. The one from the intermediate rolling section coming wire rod can also either in straight run introduced into the second rolling line and in of the finishing roller unit and sizing roller unit or via the switch in the first rolling line was introduced, there reduced cross-section in the finish rolling unit, then over the detours and the switch led into the second rolling line after passing through the Finishing roller unit can be finish-rolled in the sizing unit.
Diese erfindungsgemäße Ausbildungsform der Walzstraße verringert wegen der erheblichen Verkürzung der Gesamtanlage nicht nur den Aufwand für Fundamente und Hallen, sondern erlaubt es, die größte Temperaturabsenkung nicht schon vor der Fertigwalzeinheit, sondern in einer Temperaturausgleichsstrecke durch zwei Umführungen erheblich verlängert mit der Einsatzmöglichkeit von Kühlstrecken zwischen den Fertigwalzeinheiten vorzunehmen. Die, dadurch weiter reduzierte Temperatur des Walzgutes beim Durchgang durch die Fertigwalzeinheit und die Maßwalzeinheit erlaubt es, die Kühlstrecke zwischen diesen und der Walzgutsammeleinrichtung kürzer zu halten. Weiter können, anders als bei den bekannten gattungsgemäßen Walzstraßen dicke Walzgutabmessungen geradlinig in der zweiten Walzlinie in deren Fertigwalzeinheit mit oder ohne Einsatz der Maßwalzeinheit fertig gewalzt werden, ohne daß es dazu gleichzeitig eines Leerdurchlaufs durch die andere Fertigwalzeinheit in der ersten Walzlinie bedarf. Diese Fertigwalzeinheit läßt sich aber auch vorab mit nachfolgendem Fertigwalzen in der Maßwalzeinheit der zweiten Walzlinie einsetzen.This form of training of the rolling mill according to the invention is reduced not only because of the considerable shortening of the overall system Effort for foundations and halls, but allows the largest Lowering the temperature not before the finishing unit, but instead considerably in one temperature compensation section due to two detours extended with the use of cooling sections between the finish rolling units. The, thereby further reduced Temperature of the rolling stock as it passes through the finish rolling unit and the sizing unit allows the cooling section between them and to keep the rolling stock collector shorter. Can continue in contrast to the known generic rolling mills thick Rolling dimensions straight in the second rolling line in the Finishing roller unit finished with or without using the sizing roller unit be rolled without there being an idle run at the same time by the other finishing unit in the first rolling line. This finishing roller unit can also be used in advance with the following Insert finish rolls in the sizing unit of the second rolling line.
