Description
Die Erfindung betrifft ein Verfahren zum Längsführen eines Walzgutes, insbesondere eines warmgewalzten Stahlbandes nach den Merkmalen des Oberbegriffs von Patentanspruch 1 und ein Warmwalzwerk zur Durchführung des Verfahrens nach den Merkmalen des Oberbegriffs von Patentanspruch 8.The The invention relates to a method for longitudinal guiding a rolling stock, in particular a hot rolled steel strip after the features of the preamble of claim 1 and a hot rolling mill to carry out the method according to the characteristics of Preamble of claim 8.
Allgemein bekannt ist, dass das Walzgut in einem Warmwalzwerk, wenn es die Fertigwalzstraße verlässt, über einen Rollgang einen Laminar-Kühlbereich bis zu einem Haspelbereich durchläuft.Generally It is known that the rolling stock in a hot rolling mill, if it is the Finish rolling mill leaves, over one Roller table a laminar cooling area up to a reel area passes.
In dem Laminar-Kühlbereich wird das Walzgut mittels Wasser, zum Erreichen einer über die Breite des Walzgutes möglichst gleichmäßigen Gefügestruktur und gleichmäßiger Festigkeitseigenschaften, auf eine erforderliche Haspeltemperatur gekühlt.In the laminar cooling area is the rolling stock by means of water, to achieve over the width of the rolling stock as possible uniform microstructure and more uniform Strength properties, to a required reel temperature cooled.
Bedingt durch den Gesamtherstellungsprozess des Walzgutes entsteht unter Umständen ein ungleiches Temperaturprofil über die Breite des Walzgutes.conditioned due to the overall manufacturing process of the rolling stock arises under Circumstances an uneven temperature profile over the width of the rolling stock.
Dieses Temperaturprofil kann im Sinne einer Vergleichmäßigung durch vorzugsweise eine längs des Walzgutes und über der Breite des Walzgutes angeordneten Vorrichtung mit Abschirmelementen zum Kühlen des Walzgutes beeinflusst werden.This Temperature profile can be in the sense of equalization by preferably one along the rolling stock and over the width of the rolled material arranged device with shielding for Cooling of the rolling stock can be influenced.
Eine
solche Vorrichtung ist aus der
Der Transport des Walzgutes längs des Rollgangs erfolgt dennoch nicht immer so, dass mittels der vorgenannten Vorrichtung immer annähernd die Breite des Walzgutes gleichmäßig gekühlt wird, weil das Walzgut zum Ausschwärmen neigt, also den durch die Vorrichtung vorbestimmten Kühlbereich seitlich verlässt. Dadurch können permanent einseitig oder wechselseitig die Kantenbereiche des Walzgutes, im Vergleich zur Gesamtbreite, erhebliche Abweichungen im Temperaturprofil, in der Gefügestruktur und in der Festigkeit auftreten. Als ein besonderer Nachteil sind in diesem Zusammenhang entstehende Besäumverluste zu nennen; diese Besäumverluste führen zu einer geringen Ausbringung.Of the Transport of the rolling stock along the roller table is still done not always so that by means of the aforementioned device always approximately equal to the width of the rolling stock is cooled because the rolling stock to swarm tends, so the predetermined by the device cooling area laterally leaves. This allows permanent one-sided or alternately the edge areas of the rolling stock, in comparison to Overall width, significant deviations in the temperature profile, in the Microstructure and in the strength occur. As a particular disadvantage are arising in this context Besäumverluste to call; These edging losses lead to a low output.
Es ist daher Aufgabe der vorliegenden Erfindung, die vorgenannten Gefüge- und Festigkeitsunterschiede und die Besäumverluste des Walzgutes zu minimieren.It It is therefore an object of the present invention to provide the aforementioned structural and strength differences and the Besäumverluste of the Minimize rolling stock.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 und durch die Merkmale des Patentanspruchs 8 gelöst.The The object is achieved by the features of claim 1 and by the features of the claim 8 solved.
Nach den Merkmalen des Patentanspruchs 1 wird gemäß dem Verfahren zum Längsführen eines Walzgutes, insbesondere eines warmgewalzten Stahlbandes, das Walzgut nach dem Verlassen der Fertigwalzstraße eines Warmwalzwerkes über einen Rollgang in Richtung eines Haspels transportiert und es durchläuft dabei einen zwischen der Fertigwalzstraße und dem Haspel liegenden Laminar-Kühlbereich.To The features of claim 1 is according to the Method for longitudinally guiding a rolling stock, in particular a hot-rolled steel strip, the rolling stock after leaving the finishing train of a hot rolling mill over transports a roller table in the direction of a reel and passes through it one between the finishing train and the reel lying laminar cooling area.
Erfindungsgemäß wird das Walzgut längs und beidseitig des Laminar-Kühlbereiches durch wenigstens eine Seitenführung geführt, die aus parallel zueinander und voneinander beabstandet angeordneten Führungslinealen besteht, und zwar derart, dass es, vorzugsweise von einer über dem Walzgut angeordneten Kühlvorrichtung mit Abschirmelementen für ein flüssiges Kühlmedium, im Wesentlichen vollflächig dem Kühlmedium ausgesetzt wird.According to the invention the rolling stock along and on both sides of the laminar cooling area passed through at least one side guide, the arranged parallel to each other and spaced from each other Guide rulers consists, in such a way that it, preferably from a cooling device arranged above the rolling stock with shielding elements for a liquid cooling medium, essentially exposed to the entire surface of the cooling medium becomes.
Damit ist der Vorteil verbunden, dass das Walzgut am Ausschwärmen, das heißt, am Verlassen seiner Transportrichtung im Laminar-Kühlbereich, gehindert wird.In order to the advantage is associated that the rolling stock swarming, that is, prevented from leaving its transport direction in the laminar-cooling area becomes.
Damit wird über die Breite des Walzgutes ein gleichmäßiges Temperaturprofil bei Ausbildung einer einheitlichen Gefügestruktur und gleichmäßiger Festigkeitseigenschaften erreicht.In order to becomes a uniform over the width of the rolling stock Temperature profile when forming a uniform microstructure and achieved uniform strength properties.
Ferner werden im Ergebnis des erfindungsgemäßen Verfahrens die Besäumverluste des Walzgutes entscheidend verringert und folglich wird die Ausbringung an Walzgut gesteigert.Further become as a result of the method according to the invention significantly reduces the trimming losses of the rolling stock and consequently the yield of rolling stock is increased.
Wie bereits vorstehend erwähnt, kann das Walzgut längs des Laminar-Kühlbereiches durch mehrere Seitenführungen geführt werden. Die Seitenführungen bestehen dabei, wie erwähnt, aus beidseits des Walzgutes vorhandenen, parallel zueinander angeordneten und relativ zueinander verschiebbaren Führungslinealen.As already mentioned above, the rolling stock can be longitudinal the laminar cooling area through several side guides be guided. The side guides insist as mentioned, existing on both sides of the rolling stock, in parallel arranged mutually and relatively displaceable guide rulers.
Das Einstellen der wenigstens einen Seitenführung auf die Breite des Walzgutes erfolgt in Ausgestaltung der Erfindung automatisch, und zwar dadurch, dass nach dem Verlassen der Fertigwalzstraße die Breite des Walzgutes messtechnisch erfasst wird. Daraufhin erfolgt vorzugsweise ein grobes Einstellen der wenigstens einen Seitenführung auf die Breite des Walzgutes und nachdem der Kopf des Walzgutes die Seitenführung passiert hat, erfolgt das Einstellen auf die erfasste Breite des Walzgutes.The Setting the at least one side guide to the width of the rolling stock takes place in an embodiment of the invention automatically, by the fact that after leaving the finishing train the width of the rolling stock is detected metrologically. Thereupon takes place preferably a coarse adjustment of the at least one side guide on the width of the rolling stock and after the head of the rolling stock the side guide has passed, the adjustment is done on the detected width of the rolling stock.
Wie bereits vorstehend offenbart, kann das Einstellen der Seitenführung quer zum Transportweg des Walzgutes erfindungsgemäß in Abhängigkeit von der Position der vorzugsweise über dem Walzgut angeordneten Kühlvorrichtung mit den Abschirmelementen für ein flüssiges Kühlmedium erfolgen. In gleicher Weise kann natürlich auch die erwähnte Kühlvorrichtung auf die Position der Seitenführung ausgerichtet werden, und zwar immer unter dem Aspekt der Erzielung eines annähernd über die Breite des Walzgutes gleich bleibenden Temperaturprofils.As already disclosed above, the adjustment of the lateral guide transversely to the transport path of the rolling stock can be effected according to the invention as a function of the position of the cooling device preferably arranged above the rolling stock with the shielding elements for a liquid cooling medium.
