Description
Die Erfindung betrifft eine kontinuierliche Feinstahl- oder Drahtstraße, umfassend, hinter dem ersten Zwischenwalzabschnitt der Straße angeordnete Zwischenblöcke und Maßfertigblöcke, vor und zwischen, sowie hinter diesen angeordnete Kühlstrecken und Temperatur-Ausgleichsstrecken, sowie, diesen nachgeordnete Walzgutsammeleinrichtungen, bei der eine Mehrzahl von, im wesentlichen parallel verlaufender Führungslinien für das Walzgut über Zwischenweichen und Umführungen miteinander verbunden, das Führen des, aus dem Zwischenabschnitt der Straße kommenden Walzgutstrangs über bzw. durch vorbestimmte Abschnitte der Führungslinien und die in diesen angeordneten Walz- und Kühleinheiten, sowie Kühl- und Temperaturausgleichsstrecken ermöglichen (siehe z.B.
Drahtstraßen dieser Bauart stellen die anlagetechnische Voraussetzung für bspw. temperaturkontrolliertes Walzen dar, mit dem die mechanischen Eigenschaften des Walzgutes verbessert, dem Walzprozess nachgeschaltete Wärmebehandlungsprozesse eingespart und kontrollierte Temperaturprofile innerhalb der Walzlinie eingestellt werden können.Wire mills of this design represent the technical requirements for, for example, temperature-controlled rolling, with which the mechanical properties of the rolling stock can be improved, the heat treatment processes downstream of the rolling process can be saved and controlled temperature profiles within the rolling line can be set.
Dies thermomechanische Walzen stellt wegen der hohen Endwalzgeschwindigkeiten beim Fertigwalzen in den, als Zwischenblöcke und als Maßfertigblock ausgebildeten Walzeinheiten mit kurzen Gerüstabständen und der damit verbundenen 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 thermo-mechanical rolling, because of the high final rolling speeds in finish rolling, places it in the rolling units with short framework spacings formed as intermediate blocks and as a custom prefabricated block and the associated rolling units Heating the rolling stock during rolling particularly high demands on the temperature control which usually requires a reduction in temperature to certain levels before the finish rolling.
Nach einem bekannten Vorschlag für solche Walzstraßen (
Ein weiterer Vorschlag (
Mit diesen Walzstraßen können durch die Wahl und den Einsatz der Zwischenblöcke und der Fertigwalzeinheiten sowie der Einflußlängen der Kühleinheiten und der Temperaturausgleichsstrecken die Materialeigenschaften des Walzgutes gesteuert beeinflusst und auch den unterschiedlichen Erfordernissen beim Walzen kleiner und großer Abmessungen Rechnung getragen werden. Dies allerdings in einem mehr oder weniger beschränkten Umfang.With these rolling mills, the material properties of the rolling stock can be controlled by the choice and use of the intermediate blocks and the finishing roll units and the length of influence of the cooling units and the temperature compensation lines influenced and also the different requirements when rolling small and large dimensions are taken into account. This, however, to a more or less limited extent.
Der Erfindung liegt die Aufgabe zugrunde, diese Ausbildungsform der Walzstraße so zu verbessern, dass die Walzgutverarbeitung in Verbindung mit angepasster Beeinflussung der Materialeigenschaften durch die Kühleinheiten und der Temperaturausgleichsstrecken in einem wesentlich größeren Umfang und mit einer größeren Anzahl von Variationen ermöglicht wird.The invention has for its object to improve this embodiment of the rolling train so that the Walzgutverarbeitung in conjunction with adapted influencing of the material properties by the cooling units and the temperature compensation lines is made possible to a much greater extent and with a greater number of variations.
Diese Aufgabe wird dadurch gelöst, dass die Walzstraße hinter dem vorangegangenen Zwischenabschnitt drei Führungslinien aufweist, von denen die erste vor der Walzgutsammeleinrichtung über eine Zwischenweiche in die zweite Führungslinie mündend, einen ersten Zwischenblock und, dieser nachgeordnete Kühlund/oder Temperaturausgleichsstrecken sowie hinter dem Zwischenblock eine Zwischenweiche aufweist, die in eine 180°-Umführung führt, die in eine Zwischenweiche in der dritten Führungslinie mündet, die über eine 180°-Umführung mit dem Anfang der zweiten unmittelbar zur Walzgutsammeleinrichtung geführten Führungslinie führt, wobei vor oder hinter der Zwischenweiche eine weitere Zwischenweiche mit einer nachgeordneten 180°-Umführung angeordnet ist, die über eine Zwischenweiche in dieser Führungslinie, hinter dem Ausgang einer, in dieser Führungslinie angeordneten Zwischenblock mündet. Dabei kann erfindungsgemäß die Zwischenweiche am Ausgang der zweiten Führungslinie als Dreiarmweiche ausgebildet, mit ihrem dritten Arm über eine 180°-Umführung reversierend in den Ausgang der dritten Führungslinie führen.This object is achieved in that the rolling mill has three guide lines behind the preceding intermediate section, of which the first opens in front of the rolling stock collecting device via an intermediate switch in the second guide line, a first intermediate block and this downstream cooling and / or temperature compensation sections and behind the intermediate block an intermediate switch has, which leads to a 180 ° -Umführung, which leads into an intermediate switch in the third guide line, which leads over a 180 ° -Umführung with the beginning of the second guided directly to the rolling stock collection guide line, wherein before or behind the intermediate switch another intermediate between a downstream 180 ° -Umführung is arranged, which opens via an intermediate switch in this guide line, behind the output of an arranged in this guide line intermediate block. In this case, according to the invention, the intermediate switch at the output of the second guide line designed as a three-arm switch, with its third arm reversing over a 180 ° lead in the output of the third guide line.
Diese Drahtstraße kann, wie die Erfindung weiter vorsieht, in einem Arbeitsverfahren derart betrieben werden, dass der aus dem Zwischenabschnitt der Walzstraße kommende Walzgutstrang über die erste Führungslinie mit dem Zwischenblock und den Kühlstrecken und Temperaturausgleichsstrecken über eine Umführung in die dritte Führungslinie und von dieser über eine Umführung in die zweite Führungslinie mit dem Zwischenblock und den Kühlstrecken sowie Temperaturausgleichsstrecken dem Maßfertigblock und der Walzgutsammeleinrichtung zugeleitet werden.This wire rod can, as the invention further provides, be operated in a working method such that the rolling stock coming from the intermediate section of the rolling train via the first guide line with the intermediate block and the cooling sections and temperature compensation lines via a bypass in the third guide line and from this via a detour in the second guide line with the intermediate block and the cooling sections and temperature compensation lines the Maßfertigblock and the rolling stock collecting device are fed.
Der Walzgutstrang kann auch über die erste Führungslinie mit dem Zwischenblock und den Kühlstrecken sowie den Temperaturausgleichsstrecken über die Dreiarmweiche in die dritte Führungslinie und über eine Umführung und Zwischenweiche in die zweite Führungslinie und von dieser dem Maßfertigblock und der Walzgutsammeleinrichtung zugeführt werden.The rolling stock can also be fed via the first guide line with the intermediate block and the cooling sections and the temperature compensation lines via the three-arm switch in the third guide line and a bypass and intermediate switch in the second guide line and from this the Maßfertigblock and the rolling stock collection device.
Eine weitere erfindungsgemäße Möglichkeit besteht darin, dass der Walzgutstrang über die erste Führungslinie mit dem Zwischenblock und die Zwischenweiche sowie eine Umführung und eine weitere Zwischenweiche der dritten Führungslinie und über diese und eine Umführung der zweiten Führungslinie mit dem Zwischenblock, dem Maßfertigblock und der Walzgutsammeleinrichtung zugeleitet wird.Another possibility according to the invention is that the rolling stock is fed via the first guide line with the intermediate block and the intermediate switch and a bypass and a further intermediate switch of the third guide line and on this and a deflection of the second guide line with the intermediate block, the Maßfertigblock and the rolling stock collection device ,
Schließlich kann die Drahtstraße auch so betrieben werden, dass der Walzgutstrang über die erste Führungslinie mit dem Zwischenblock und den Kühlstrekken sowie Temperaturausgleichsstrecken über die Dreiarmweiche unmittelbar dem Maßfertigblock sowie der anschließenden Walzgutsammeleinrichtung zugeleitet wird.Finally, the wire rod can also be operated so that the rolling stock is fed via the first guide line with the intermediate block and the Kühlstrekken and temperature compensation lines on the three-arm switch directly to the Maßfertigblock and the subsequent rolling stock collection device.
Die beiden an erster und zweiter Stelle beschriebenen Arbeitsverfahren ermöglichen bei Drahtstärken von 5,0 und 11,0 sowie 11,0 bis 22,0 mm ein Walzen mit intensiver Kühlung bei gutem Temperaturausgleich und niedrigen Einlauf-, Auslauf- und Fertigwalztemperaturen in den Zwischenblöcken und dem Maßfertigblock, während bei den anschließend beschriebenen beiden Arbeitsverfahren für die genannten Drahtstärken mit geringerer Kühlung und höheren Einlauf- und Fertigtemperaturen gearbeitet werden kann.The two working methods described in the first and second place at wire thicknesses of 5.0 and 11.0 and 11.0 to 22.0 mm allow intensive cooling with good temperature compensation and low inlet, outlet and finish rolling temperatures in the intermediate blocks and the Maßfertigblock, while in the subsequently described two working methods for the mentioned wire thicknesses with lower cooling and higher inlet and finishing temperatures can be worked.

Da die Walzguttemperatur beim Austritt aus der Zwischenstraße erfahrungsgemäß etwa 1.050 - 1.100 C° beträgt, kann mit den Kühlstrecken eine Kühlung des Walzgutstranges auf mindestens etwa 750 C° bewirkt werden. Die relativ langen Ausgleichstrecken hinter bzw. zwischen den Kühlstrecken erlauben es einen guten Temperaturausgleich zwischen Kern und Oberfläche des Walzgutstranges herbei zu führen und dadurch diesen im Maßfertigblock mit einer niedrigen, ausgeglichenen Walzguttemperatur fertig zu walzen.Since the rolling stock temperature at exit from the intermediate road is, according to experience, approximately 1,050-1,100 C °, the cooling sections can be used to cool the rolling stock to at least approximately 750 ° C. The relatively long compensation distances behind or between the cooling sections allow it to bring about a good temperature balance between the core and surface of Walzgutstranges hereby and thereby finish rolling in Maßfertigblock with a low, balanced Walzguttemperatur.
