Abstract
Description
Die Erfindung bezieht sich auf ein Arbeitsverfahren zum Walzen von Rundquerschnitten vorgegebener genauer Fertigmaße in einer, hinter einer Drahtwalzstraße angeordneten, aus dicht hintereinander angeordneten, anstellbaren Horizontal-, Vertikal- und Horizontal-Duowalzgerüsten bestehenden Walzgerüstgruppe.The invention relates to a working method for rolling round cross sections of predetermined precise finished dimensions in a roll stand group, which is arranged behind a wire rolling mill and consists of closely arranged, adjustable horizontal, vertical and horizontal duo-roll stands.
Es sind zahlreiche Vorschläge zu Arbeitsverfahren dieser Art und Walzgerüstgruppen zur Durchführung solcher Arbeitsverfahren bekanntgeworden; so die Anordnung von Dreiwalzengerüsten in Blöcken zu drei Gerüsten (Brauer "Weiterentwicklungen der Dreiwalzen-Umformblöcke", Stahl und Eisen 112/192, Nr. 7) und von Zweiwalzengerüsten mit zweiseitiger Lagerung der Walzen, ebenfalls in Blöcken zu drei Gerüsten (Werksprospekt Morgan Construction Co. "TEKISUN BAR SIZING MILL TECHNOLOGY").Numerous proposals for working methods of this type and rolling mill groups for carrying out such working methods have become known; So the arrangement of three-roll stands in blocks to three stands (Brauer "further developments of the three-roll forming blocks", steel and iron 112/192, No. 7) and of two-roll stands with two-sided storage of the rolls, also in blocks of three stands (Morgan Construction company brochure Co. "TEKISUN BAR SIZING MILL TECHNOLOGY").
Gemeinsam ist diesen bekannten Arbeitsverfahren, daß sie mit verhältnismäßig geringen Gesamtstichabnahmen, maximal etwa 14% und einer daraus resultierenden beschränkten Leistung arbeiten, und daß für die verwendeten Walzgerüstgruppen ein verhältnismäßig großer Bauaufwand, insbesondere bei den Dreiwalzenblöcken für Walzenlagerung und Walzenantrieb und bei allen Walzgerüstgruppen für die Gerüste selbst wegen der notwendigen außerordentlichen Gerüststeifigkeiten mit Federkonstanten von 0,004 mm/kN und weniger, verbunden mit einer hohen Anstellgenauigkeit erforderlich ist.What these known working methods have in common is that they work with relatively low total stitch reductions, a maximum of about 14% and a resulting limited output, and that for the roll stand groups used, a relatively large amount of construction work, in particular for the three-roll blocks for roll storage and roll drive and for all roll stand groups for the Scaffolding itself is necessary because of the necessary extraordinary scaffolding rigidity with spring constants of 0.004 mm / kN and less, combined with a high adjustment accuracy.
Die Erfindung hat erkannt, daß sich für die Praxis gute Rundquerschnitte mit vergleichbar guter Genauigkeit der Fertigmaße auch walzen lassen, wenn bei einer bedeutend stärkeren Stichabnahme zwischen 14% bis 28% innerhalb der beiden ersten Walzgerüste deren Walzgeschwindigkeit so bemessen wird, daß nur ein geringer Zug auftritt und bei Einstellung einer Abnahme von 1% bis 5% im letzten Walzgerüst, die Kraft des Antriebes dieses Walzgerüstes so begrenzungsgeregelt wird, daß der Querschnitt des Walzgutes zwischen diesem Walzgerüst und dem vorangehenden keine Verminderung erfährt.The invention has recognized that, in practice, good round cross-sections can also be rolled with comparable good accuracy of the finished dimensions, if the roll speed is measured within the first two roll stands with a significantly higher pass reduction, so that only a small train occurs and when setting a decrease of 1% to 5% in the last roll stand, the force of the drive of this roll stand is controlled so that the cross section of the rolling stock between this roll stand and the previous one is not reduced.
Die Walzgerüstgruppe zur Durchführung dieses Arbeitsverfahrens kann erfindungsgemäß einen, das erste und das zweite Walzgerüst gemeinsam antreibenden Motor und einen, das dritte Walzgerüst antreibenden Motor, diesen mit einstellbarer Strombegrenzung aufweisen.According to the invention, the roll stand group for carrying out this working method can have a motor which drives the first and the second roll stand together and a motor which drives the third roll stand, with an adjustable current limitation.
Der Wert der Gerüstfederung der Walzgerüste der Walzgruppe kann, wie die Erfindung weiter vorsieht, auf etwa 0,001 mm/kN beschränkt werden, und die Walzen können, fliegend gelagert, bei einem Abstand der Walzgerüste untereinander von etwa 600 bis 750 mm, als Walzscheiben einen Scheibendurchmesser von 130 bis 300 mm aufweisen. Vor und hinter der Walzgerüstgruppe können bekannte Schlingenbildner angeordnet werden, die einen die Abmaße des Walzgutes selbst und die Arbeitsweise der Walzgerüstgruppe nicht beeinflussenden Übergang aus den vorangehenden und den anschließenden Aggregaten der Walzenstraße gewährleisten.The value of the stand suspension of the roll stands of the roll group can, as the invention further provides, be limited to approximately 0.001 mm / kN, and the rolls, on the fly, with a distance between the roll stands of approximately 600 to 750 mm, as roll disks, have a disk diameter have from 130 to 300 mm. Known loop formers can be arranged in front of and behind the roll stand group, which ensure a transition from the preceding and the subsequent units of the roll train which does not influence the dimensions of the rolling stock itself and the operation of the roll stand group.
Vorteilhaft verlaufen bei den Kalibern des ersten und des zweiten Walzgerüstes der Walzgerüstgruppe die Umfangslinien der Bodenbereiche der, diese Walzenkaliber bildenden Kaliberrinnen etwa oval und anschließend in Richtung auf die jeweiligen beiden Randkanten der Kaliberrinne geradlinig, spitzwinklig aufeinander zu.In the case of the calibers of the first and the second roll stand of the roll stand group, the circumferential lines of the bottom regions of the caliber channels forming these roll calibers advantageously run approximately oval and then straight towards one another at an acute angle in the direction of the respective two peripheral edges of the caliber channel.

Wie aus Fig. 1 zu ersehen, sind die Walzgerüste 1 und 3 als Horizontalgerüste mit fliegend gelagerten Walzscheiben 4 und 5 und das zwischen diesen angeordnete Walzgerüst 2 als Vertikalgerüst 2 ausgebildet. Die Walzscheiben 6 dieses Horizontalgerüstes 2 sind - nicht dargestellt - ebenfalls fliegend gelagert. Alle Gerüste 1, 2 und 3 stehen erkennbar dicht nebeneinander. Die Gerüste 1 und 2 werden gemeinsam über ein Getriebe 7 von einem Motor 8 angetrieben und das Gerüst 3 separat von einem Motor 9.As can be seen from FIG. 1, the rolling stands 1 and 3 are designed as horizontal stands with
Das Diagramm nach Fig. 2 gibt den Verlauf der Strombegrenzung IM in Abhängigkeit von der Walzgeschwindigkeit wieder, die die Walzarbeit WA und die mechanischen Reibungen MR berücksichtigt. Der zum Betrieb des Walzgerüstes erforderliche Leistungsüberschuß ist dabei immer kleiner zu bemessen als die Zugfestigkeit des durchlaufenden Walzgutes um eine Querschnittsbeeinflussung zu vermeiden.The diagram according to FIG. 2 shows the course of the current limitation I M as a function of the rolling speed, which takes the rolling work WA and the mechanical friction MR into account. The excess power required to operate the roll stand must always be smaller than the tensile strength of the rolling stock in order to avoid influencing the cross section.
Aus den Fig. 3, 4 und 5 geht der Verlauf der Umfangslinien der Kaliber der Gerüste 1 (Fig. 3), 2 (Fig. 4) und 3 (Fig. 5) hervor. Im Bodenbereich B der Kaliber der Gerüste 1 und 2 verlaufen die Umfangslinien ellipsenförmig oval und daran anschließend, in Bereichen R in Richtung auf die jeweiligen beiden Randkanten K der Kaliber geradlinig spitzwinklig aufeinander zu, wobei die Winkel im Kaliber des Gerüstes 1 30°-60°, im Kaliber des Gerüstes 2 30°-60° betragen. Das Fertigkaliber des Gerüstes 3 ist dann ein Rundkaliber.3, 4 and 5 show the course of the circumferential lines of the calibres of the stands 1 (FIG. 3), 2 (FIG. 4) and 3 (FIG. 5).
