Description

Bei Mehrrollenwalzwerken mit zwei Arbeitswalzen und mehr als vier Stützwalzen wurde bisher der äußere Kranz der Stützwalzen, welche in Nadel-oder Rollenlagern den. Walzdruck aufnehmen und auf die Ständer übertragen, im Durchmesser gleich gemacht. Es war nicht erkannt worden, daß der Kraftverlauf in. denletzten Stützwalzen so ist, daß nur die beiden äußeren Stützwalzen den Hauptteil des Walzdruckes, aufnehmen, während die mittleren Stützwalzer, die je zwei der Zwischenstützwalzen abstützen, nur einen geringen Teil des Walzdruckes aufzunehmen. haben. Es wird vorgeschlagen, die äußeren, in Richtung der größeren Kraftkomponente liegenden Stützwalzen, welche nur eine der Stützwalzen abstützen, größer zu machen als die mittleren Stützwalzen, welche je zwei der Zwischenwalzen abstützen. In Abb. i ist die bisherige Bauart z. B. eines Zwölfzollenwalzwerkes und in Abb. z die neue Bauart eines Zwölfrollenwalzwerkes, in Abb. 3 die bisherige Bauart eines Zwanzigrollengerüstes und in Abb. 4 die neue Bauart eines Zwölf-oder VierzehnroIlengerüstes därgestellt. Aus den eingezeichneten Kräfteplänen in Abb. i ist zu ersehen, daß_die mittleren Stützwalzen C2 vom Walzdruck über die Walzen Bi, B2 nur einen. geringeren Teil aufzunehmen haben, während der Hauptteil auf die äußeren Stützwalzen Cl, C3 entfällt. Es werden daher erfindungsgemäß, wie in Abb. 3 dargestellt, die mittleren Stützwalzen. C2 nur so groß gemacht, daß sie den: geringen Walzdruck aufnehmen können, während man. die äußeren Stützwalzen C1 und 'C3 erheblich viel größer machen kann. In der Abb. a. sind derartige Walzenabmessungen mit den zugehörigen Kraftplänen dargestellt.For multi-roll mills with two work rolls and more than four Back-up rolls was previously the outer ring of the back-up rolls, which in needle or Roller bearings. Record rolling pressure and transfer it to the stand, in diameter made the same. It had not been recognized that the force curve in the last Back-up rolls is such that only the two outer back-up rolls the main part of the rolling pressure, record, while the middle back-up rolls, the two of the intermediate back-up rolls support to absorb only a small part of the rolling pressure. to have. It is suggested, the outer back-up rollers lying in the direction of the greater force component, which support only one of the back-up rolls, to make it larger than the middle back-up rolls, which each support two of the intermediate rollers. In Fig. I is the previous design z. B. a twelve-inch rolling mill and in Fig.z the new type of twelve-roller rolling mill, in Fig. 3 the previous design of a twenty-roll stand and in Fig. 4 the new one The construction of a twelve- or fourteen-roll frame is shown. From the drawn Power plans in Fig. I can be seen that_the middle backup rolls C2 from the rolling pressure over the rollers Bi, B2 only one. have to absorb less part during the The main part of the outer backup rolls C1, C3 is omitted. There are therefore according to the invention as shown in Fig. 3, the middle backup rolls. C2 just made so big that they can absorb the low rolling pressure while one. the outer backup rolls C1 and 'C3 can make considerably much larger. In Fig. A. are such roll dimensions shown with the associated force plans.

Bei der Anwendung dieser Prinzipien ist es z. B. möglich, wie in Abb. 3 und 4 dargestellt, an Stelle eines Zwanzigrollenwalzwerkes (Abb. 3) ein Zwölfrollenwalzwerk (Abb.4) zu verwenden, bei gleichem Durchmesser der am höchsten belasteten äußeren Arbeitswalzen. Falls die mittlere Stützwalze etwa die auftretenden Drücke nicht aufnehmen könnte, kann über dieser noch eine weitere größere Stützwalze angeordnet werden, so daß dann ein Vierzehnrollenwalzwerk entsteht. Diese Walze ist in Abb. 4 strichpunktiert eingezeichnet.When applying these principles it is z. B. possible, as in Fig. 3 and 4, instead of a twenty-roller mill (Fig. 3) a twelve-roller mill (Fig.4) should be used with the same diameter of the most heavily loaded outer Work rolls. If the middle back-up roll is not able to withstand the pressures that occur could accommodate, can be arranged above this yet another larger backup roller so that a fourteen-roller mill is created. This roller is shown in Fig. 4 indicated by dash-dotted lines.

Es ist auch möglich, das Zwanzigrollenwalzwerk so auszubilden, daß die beiden äußeren tragenden Stützwalzen größer gemacht werden als die beiden inneren Stützwalzen und diese beiden Stützwalzen gegebenenfalls wieder durch eine größere Stützwalze abgestützt werden, so daß ein Zweiundzwanzigrollengerüst entsteht.It is also possible to train the twenty-roller mill so that the two outer supporting back-up rolls are made larger than the two inner ones Back-up rolls and these two back-up rolls possibly again by a larger one Support roll are supported, so that a twenty-two roll frame is formed.
