Description
Die Erfindung betrifft ein Steckel-Walzwerk mit mindestens einem Reversiergerüst sowie einlauf- und auslaufseitig zum Reversiergerüst angeordneten Treibern und Wickelöfen, die über Rollgänge für das zu walzende Band miteinander verbunden sind, wobei in mindestens einem der zwischen den Wickelöfen und dem Reversiergerüst gebildeten Abschnitte mindestens eine Heizvorrichtung vorgesehen ist, die mindestens einen Bereich des jeweiligen Abschnittes abdeckt und wobei mindestens eine Regelvorrichtung vorgesehen ist, die in Abhängigkeit von der Bandtemperatur die Heizleistung zu beeinflussen vermag.The invention relates to a Steckel mill with at least one Reversing scaffold and on the inlet and outlet sides of the reversing scaffold arranged drivers and winding ovens, which have roller tables for the strip to be rolled are connected to each other, with at least one of those formed between the winding furnaces and the reversing stand Sections at least one heating device is provided, which covers at least one area of the respective section and wherein at least one control device is provided, which in Depending on the strip temperature to influence the heating output can
Derartige Steckel-Walzwerke sind aus der JP-A-59 191502 bekannt. Sie arbeiten wie folgt: Das vorgewalzte Band wird unter dem einlaufseitigen Wickelofen und durch den einlaufseitigen Treiber ins Reversiergerüst zum Anstich eingeführt. Nach dem ersten Stich wird das Walzgut in den auslaufseitigen Wickelofen eingefädelt. Nachdem das Band im auslaufseitigen Wickelofen angewickelt worden ist wird zwischen dem Wickelofen und dem Reversiergerüst ein vorgegebener Bandzug aufgebaut und das Band mit entsprechender Geschwindigkeit gewalzt. Läuft das Bandende in das Steckel-Walzwerk ein, so wird die Anlage derart abgebremst, daß das Bandende zwar hinter dem Walzspalt des Reversiergerüstes, jedoch vor dem auslaufseitigen Treiber zum Stillstand kommt. Während des Reversierens wird der Walzspalt für den nächsten Stich angestellt. Der auslaufseitige Treiber führt das Band zum Anstich ins Reversiergerüst ein. Nach dem Anstich zum zweiten Stich wird das Band in den einlaufseitigen Wickelofen einfädelt. Der Bandanfang kommt am Ende des zweiten Stichs zwischen dem einlaufseitigen Treiber und dem Reversiergerüst zum Stillstand.Such Steckel rolling mills are known from JP-A-59 191502. They work as follows: The pre-rolled strip is under the inlet side Winding furnace and through the inlet-side driver Reversing frame introduced for tapping. After the first stitch the rolling stock is threaded into the winding furnace on the outlet side. After this the tape has been wound in the winding furnace on the outlet side a predetermined between the winding furnace and the reversing stand Belt tension built up and the belt at appropriate speed rolled. If the end of the strip runs into the Steckel rolling mill, the system braked so that the end of the tape behind the Rolling nip of the reversing stand, but in front of the outlet side Driver comes to a standstill. During reversing the Roll gap set for the next pass. The outlet side The driver inserts the tape into the reversing frame for tapping. To After tapping the second stitch, the tape is inserted into the inlet side Threading the winding oven. The beginning of the band comes at the end of the second Stab between the driver on the inlet side and the reversing frame to a standstill.
Während des Reversiervorgangs, der durch Abbremsen, Ausfädeln, Reversieren, Anstechen und Einfädeln bestimmt ist wird sowohl das Bandende als auch der Bandanfang gegenüber dem mittleren Bereich des Bandes stärker abgekühlt. Die stärkere Abkühlung ergibt sich dadurch, daß diese Bandbereiche während des Reversiervorgangs alternierend nicht im Wickelofen auf Temperatur gehalten werden. Am Bandanfang und am Bandende erfolgt zumindest in den ersten Stichen zudem eine zusätzliche Kühlung, wenn diese Bandbereiche auf den, auf eine bestimmte Temperatur eingestellten, gekühlten Wickeldorn des Wickelofens aufgewickelt werden.During the reversing process caused by braking, unthreading, Reversing, piercing and threading is both determined Band end as well as the beginning of the band opposite the middle area of the tape cooled more. The stronger cooling results in that these band areas during the reversing process alternately not to be kept at temperature in the winding furnace. At the beginning and end of the band, at least in the first Stitches also provide additional cooling when these band areas open the cooled mandrel set to a certain temperature of the winding furnace.
Die JP-A-59 191502 weist dazu Temperaturfühler auf und beeinflußt die Temperatur des Bandanfangs bzw. des Bandendes über die Heizvorrichtungen dahingehend, daß ein Angleich an die übrige Bandtemperatur erfolgt. Die Messvorrichtung sind träge und ungenau, so daß eine optimale Anpassung der Bandtemperaturen nicht gewährleistet ist.For this purpose, JP-A-59 191502 has temperature sensors and influences them the temperature of the beginning or end of the strip via the heating devices in that an adjustment to the remaining strip temperature he follows. The measuring device is slow and imprecise, so that a optimal adjustment of the strip temperatures is not guaranteed.
Der Erfindung liegt die Aufgabe zugrunde, Steckel-Walzwerke so auszugestalten, daß über die Bandlänge keine großen Walzkraftschwankungen zu verzeichnen sind, das Band mit gleichbleibender Qualität gewalzt und Ausschuß vermieden wird.The invention is based, so Steckel rolling mills to design that there are no large fluctuations in rolling force over the length of the strip the tape is of constant quality rolled and scrap is avoided.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Die hier vorgeschlagene Lösung bewirkt, daß vorherbestimmte Bereiche des Bandes vor allem der nicht im geheizten Wickelofen befindliche Teil des Walzbandes auf eine, dem übrigen Walzband entsprechend angepaßte Temperatur gebracht werden kann. This object is solved by the features of claim 1. The Solution proposed here causes predetermined areas of the belt, especially the one that is not in the heated winding furnace Part of the rolled strip on one, corresponding to the rest of the rolled strip adjusted temperature can be brought.
Aus der SU-A-728 955 sind zwar regelbare Heizvorrichtungen bekannt, die aufgrund von Bandpositionssensoren gesteuert werden, eine Bandverfolgung wird hier jedoch nicht vorgeschlagen.Adjustable heating devices are known from SU-A-728 955, controlled by belt position sensors, one However, band tracking is not suggested here.
Ist eine Schaltvorrichtung vorgesehen, die jeweils nur die Heizvorrichtung aktiviert, welche jeweils in Bandlaufrichtung vor dem Reversiergerüst angeordnet ist, so wird sichergestellt, daß das Band vor dem Stich im Reversiergerüst entsprechend aufgeheizt wird, daß das aus dem Reversiergerüst auslaufende Band jedoch keinem Heizvorgang unterworfen wird.If a switching device is provided, each only the heating device activated, each in the tape running direction before the Reversing frame is arranged, so it is ensured that the belt Before the stitch in the reversing frame is heated accordingly however, the strip running out of the reversing stand does not heat up is subjected.
