Abstract

A bridle unit assigned to a rolling stand with several rolls arranged in adjustable positions below and above the strip flow, which can be moved by means of a drive from an initial position to the strip and from the strip back into the initial position, wherein the roll situated closest to the roll gap of the rolling stand can be moved by means of an additional drive from an initial position below the strip flow or from an initial position above the strip flow to the strip, such that, when the bridle unit is used for coloring the strip, the circumference of the roll deflects the strip upward or downward from the horizontal pass line and forms a bite angle above or below the pass line.

Description

Die Erfindung betrifft eine einem Walzgerüst zugeordnete Bridleeinheit mit mehreren verstellbar unterhalb und oberhalb des Bandlaufs angeordneten Rollen, die mittels eines Antriebs aus einer Ausgangsposition zum Band hin und vom Band zurück in die Ausgangsposition bewegbar sind.The invention relates to a rolling mill associated Bridleeinheit with several adjustable below and above the tape arranged rollers, by means of a drive from a home position to the tape and from the tape back in the starting position are movable.

Bridleeinheiten führen und richten das Band und halten dessen Zugspannung aufrecht, indem oberhalb des Bandlaufs angeordneten verstellbaren Rollen mittels des Antriebs aus der Ausgangsposition auf die Bandoberfläche in eine Arbeitsposition abgesenkt werden. Das in der Arbeitsposition wechselweise gebogene Band verläßt die Bridleeinheit an der dem Walzspalt des zugeordneten Walzgerüstes nächstgelegenen Rolle in Höhe der Durchlauflinie des Walzgerüstes.Bridle units guide and straighten the belt and maintain its tension by arranged above the tape run adjustable rollers by means of Drive from the initial position on the belt surface in a working position be lowered. The alternately bent band leaves in the working position the Bridleeinheit at the nip of the associated rolling mill nearest Roller at the level of the pass line of the roll stand.

Derartige Bridleeinheiten sind beispielsweise aus JP - A - 52 052852, JP - A - 51 109264 und US - A - 2,768;542 bekannt. Aus der US - Schrift ist weiterhin bekannt, das eine dem Walzspalt des Walzgerüstes nächstgelegene Rolle sowohl von oben wie auch von unten an das Band angestellt werden kann.Bridle units of this type are known, for example, from JP-A-52 052852, JP-A-51 No. 109,264 and US Pat. No. 2,768,542. It is further known from US Pat. the one closest to the roll gap of the roll stand both from above as can be made from below to the band.

Sofern eine Colorierung des Bandes gefordert ist, muß eine zusätzliche Colorrolle zwischen der Bridleeinheit und dem zugeordneten Walzgerüst eingesetzt werden. Die zusätzliche Colorrolle und die zu deren Betrieb erforderlichen mechanischen Einrichtungen verlängern den Abstand zwischen dem Walzspalt des Walzgerüstes und der Abhaspelung des Bandes. Mit dem größeren Abstand zwischen Walzspalt und Abhaspelung sind jedoch Verfahrensnachteile, insbesondere größere Abmaßlängen verbunden.If a coloring of the tape is required, an additional color roll must be used between the Bridleeinheit and the associated rolling mill. The additional color roll and the mechanical equipment required for its operation extend the distance between the nip of the roll stand and the unwinding of the band. With the larger distance between nip and However, uncoiling are procedural disadvantages, in particular larger dimension lengths connected.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Bridleeinheit zu schaffen, die eine Colorierung des Bandes ohne Verlängerung der Distanz zwischen Walzspalt und Abhaspelung ermöglicht. The invention is therefore an object of the invention to provide a Bridleeinheit, the a coloring of the tape without lengthening the distance between the nip and uncoiling allows.

Die Lösung dieser Aufgabe basiert auf dem Gedanken, die dem Walzspalt des Walzgerüstes nächstgelegene Rolle zu entkoppeln, so daß die Rolle wahlweise als Bridlerolle oder Colorrolle verwendbar ist.The solution to this problem is based on the idea that the nip of the mill stand decouple the next roll so that the roll can be used as a bridle roll or color roll is usable.

Im einzelnen wird die Aufgabe bei einer Bridleeinheit der eingangs erwähnten Art dadurch gelöst, dass die dem Walzspalt des Walzgerüstes nächstgelegene Rolle mittels eines Zusatzantriebs aus einer Ausgangsposition unterhalb des Bandlaufs oder aus einer Ausgangsposition oberhalb des Bandlaufs zum Band hin bewegbar ist, wobei der Umfang der Rolle bei einem Einsatz der Bridleeinheit zur Colorierung des Bandes das Band nach oben oder unten von der horizontalen Durchlauflinie ablenkt und einen Einlaufwinkel oberhalb oder unterhalb der Durchlauflinie bildet.In particular, the object is a Bridleeinheit of the type mentioned solved by the roller closest to the roll gap of the roll stand by means of an additional drive from a starting position below the tape run or from a starting position above the tape to the tape movable is, wherein the scope of the role when using the Bridleeinheit to Colorize the tape the tape up or down from the horizontal Throughline deflects and an inlet angle above or below the Pass line forms.

Verharrt die walzspaltnahe Rolle in ihrer Ausgangsposition unterhalb des Bandlaufs auf Höhe der dort fest angeordneten Bridierollen, arbeitet sie in konventioneller Welse als Bridlerolle. Das Band verläßt die Bridleeinheit in Höhe der Durchlauflinie des Walzgerüstes.Maintains the roll near the roll gap in its starting position below the strip run at the level of the Bridierollen fixed there, she works in conventional catfish as a bridle role. The tape leaves the bridle unit at the level of the pass line of the Rolling stand.

Soll die walzspaltnahe Rolle als Colorrolle arbeiten, wird sie aus der Ausgangsposition oberhalb oder unterhalb des Bandlaufes, soweit auf das Band bewegt, daß das Band von der Bridleeinheit in den Walzspalt unter einem spitzen Winkel zur Durchlauflinie des Walzgerüstes einläuft:

  • Zur Colorierung der Bandoberseite senkt man die Colorrolle aus der Ausgangsposition oberhalb des Bandes ab, bis sich die Achse der walzspaltnahen Rolle etwas unterhalb der Achsen der übrigen verstellbaren Rollen in Arbeitsposition befindet.
  • Zur Colorierung der Bandunterseite hebt man die Colorrolle aus der Ausgangsposition unterhalb des Bandes an, bis sich die Achse der walzspaltnahen Rolle etwas oberhalb der Achsen der fest unterhalb des Bandlaufs angeordneten Rollen befindet.
    • If the roller gap close roll to work as Colorrolle, it is from the starting position above or below the tape, as far as moving on the tape that the tape from the Bridleeinheit enters the nip at an acute angle to the pass line of the rolling mill:
  • To color the upper side of the tape to lower the color roll from the starting position above the tape until the axis of the roll near the roll gap is slightly below the axes of the other adjustable rollers in working position.
  • To color the underside of the belt to raise the color roll from the starting position below the tape until the axis of the roll near the roller gap is slightly above the axes of the fixed below the tape running rollers.

    • Aufgrund der Möglichkeit, die walzspaltnahe Rolle wahlweise als Bridie- oder Colorrolle einsetzen zu können, vergrößert sich der Abstand zwischen Walzspalt und Abhaspelung auch dann nicht, wenn eine zusätzliche Colorierung des Bandes erforderlich ist.Due to the possibility, the roll gap close roll either as Bridie or Colorrolle to be able to use, increases the distance between the nip and unraveling even if an additional coloring of the Bandes is required.

    Wenn die dem Walzspalt des Walzgerüstes nächstgelegene Rolle in beliebige Zwischenpositionen zwischen den Ausgangspositionen oberhalb und unterhalb des Bandlaufs bewegbar ist, lassen sich unterschiedliche Einlaufwinkel zur Durchlauflinie bei der Colorierung des Bandes einstellen. Außerdem erlaubt dieses Merkmal eine verbesserte Anpassung der Bridleeinheit an Bänder unterschiedlicher Dicke sowohl im Bridle- als auch Colorierungsmodus. Verfahrenstechnisch sinnvolle Einlaufwinkel bewegen sich zwischen +/- 14° gegenüber der Durchlauflinie.If the roller closest to the roll gap of the roll in any Intermediate positions between the starting positions above and below the tape run is movable, can be different entry angle to Set the pass line when coloring the ribbon. Also allowed this feature an improved adaptation of the bridle unit to different bands Thickness in both Bridle and Colorize modes. process engineering reasonable entry angles are between +/- 14 ° the pass line.

    Um beliebige Zwischenposition der walzspaltnahen Rollen, insbesondere rechnergestützt einstellen zu können, ist in vorteilhafter Ausgestaltung der Erfindung ein Positionsgeber vorgesehen, der die Lage der Rolle erfaßt.To arbitrary intermediate position of the roll gap near rollers, in particular computer-aided to be able to adjust is in an advantageous embodiment of the invention a position sensor is provided which detects the position of the roller.

    Der Zusatzantrieb für die walzspaltnahe Rolle ist in zweckmäßiger Ausgestaltung der Erfindung als beidseitig beaufschlagbarer, druckmittelbetriebener, insbesondere hydraulischer Zylinder ausgestaltet. Alternativ ist jedoch auch der Einsatz anderer mechanischer oder elektrischer Antriebe möglich, die eine im wesentlichen vertikale Verfahrbarkeit der walzspaltnahen Rolle aus einer Ausgangsposition oberhalb und unterhalb des Bandlaufs in unterschiedliche Zwischenpositionen für den Bridle-Cotor-Betrieb der Rolle ermöglichen.The additional drive for the roll gap close roll is in an appropriate embodiment the invention as both sides acted upon, fluid-operated, in particular designed hydraulic cylinder. Alternatively, however, is also the Use of other mechanical or electrical drives possible, the one in the essential vertical movability of the roller gap close roll from a starting position above and below the tape in different intermediate positions for the Bridle Cotor operation of the roll.

    Die erfindungsgemäße Bridleeinheit ist bei sämtlichen Walzgerüsten zum Walzen von NE-Metallen oder Stählen einsetzbar, bei denen eine Bridleeinheit mit mehreren Rollen erforderlich ist und gleichzeitig die Forderung eines von der Durchlauflinie abweichenden Einlaufwinkels des Bandes in das Walzgerüst besteht. Sind die Walzgerüste nicht als Einweg- sondern als Reversiergerüste ausgeführt, ist vorzugsweise beidseitig die erfindungsgemäße Bridleeinheit anzuordnen. The Bridle unit according to the invention is for all rolling mills for rolling of non-ferrous metals or steels in which a Bridle unit with several roles is required and at the same time the requirement of one of the Pass line deviating inlet angle of the strip in the roll stand is. Are the rolling stands not as a one-way but as Reversiergerüste executed, it is preferable to arrange the Bridle unit according to the invention on both sides.

    Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles des näheren erläutert:The invention will be described with reference to an embodiment of the closer explains:

    Figur 1 zeigt eine einem teilweise dargestellten Walzgerüst 1 zugeordnete Bridleeinheit 2, deren oberhalb des Bandlaufs angeordnete Rollen 3 aus der in der Figur 1 dargestellten Ausgangsposition in eine Arbeitsposition verfahrbar sind, in der die Rollen 3 auf dem Band 4 aufliegen (vgl. Figuren 2b, 3b und 4b.FIG. 1 shows a rolling stand 1 which is partially shown Bridle unit 2, whose arranged above the tape rollers 3 from the in The starting position shown in Figure 1 movable in a working position are in which the rollers 3 rest on the belt 4 (see Figures 2b, 3b and 4b.

    Unterhalb des Bandlaufs sind versetzt zu den Rollen 3 zwei weitere Rollen 5 fest in Lagerungsböcken 6 angeordnet, deren Rollenmäntel 7 sich bis an die in Figur 1 dargestellte Durchlauflinie 8 des nicht dargestellten Bandes 4 erstrekken.Below the tape are offset from the rollers 3 two other roles. 5 fixedly arranged in bearing blocks 6, the roller shells 7 are up to the in Figure 1 shown pass line 8 of the belt 4 not shown extend.

    Eine dem Walzspalt 9 des Walzgerüstes 1 nächstgelegene Rolle 11 der Bridleeinheit 2 ist vertikal zur Durchlauflinie 8 aus der in Figur 1 dargestellten Ausgangsposition 12 unterhalb des Bandlaufs in eine in Figur 3a dargestellte Ausgangsposition 13 oberhalb des Bandlauf sowie jede Position zwischen den Ausgangspositionen 12 und 13 bewegbar. A roller 11 of the rolling stand 1 closest to the roll gap 9 of the roll stand 1 2 is vertical to the pass line 8 from the starting position shown in Figure 1 12 below the tape in a starting position shown in Figure 3a 13 above the tape and each position between the Starting positions 12 and 13 movable.

    Die Ausgangsposition 12 der walzspaltnahen Rolle 11 entspricht der Position der fest unterhalb des Bandlaufs angeordneten Rollen 5, während die Ausgangsposition 13 der walzspaltnahen Rolle 11 der Ausgangsposition der oberhalb des Bandlaufs angeordneten verstellbaren Rollen 3 entspricht, (vgl. Figur 3a).The starting position 12 of the roller gap near roller 11 corresponds to the position the fixed below the tape running rollers 5, while the starting position 13 of the roll gap near roll 11 of the starting position of above the tape running arranged adjustable rollers 3 corresponds (see FIG 3a).

    Zur Erläuterung der unterschiedlichen Betriebsmodi der erfindungsgemäßen Bridleeinheit wird nachfolgend auf die Figuren 2-4 Bezug genommen, wobei jeweils die Figuren 2a, 3a und 4a das Einfädeln des Bandes für den jeweiligen Betriebsmodus und die Figuren 2b, 3b und 4b den Betriebsmodus selbst zeigen:To explain the different modes of operation of the invention Bridle unit will be referred to below to Figures 2-4, wherein FIGS. 2 a, 3 a and 4 a show the threading of the band for the respective one Operating mode and Figures 2b, 3b and 4b show the operating mode itself:

    Soll die Bridleeinheit im Bridlemodus nach Figur 2b betrieben werden, verbleibt die walzspaltnahe Rolle 11 in ihrer Ausgangsposition 12 auf Höhe der fest angeordneten Rollen 5. Die an einem Tragrahmen 14 angeordneten Rollen 3 bewegt ein Hydraulikzylinder 15 aus der Ausgangsposition 16 in Richtung der Oberseite des Bandes 4, so daß das Band 4 durch die Rollen 3, 5, 11 wechselweise gebogen und die walzspaltnahe Rolle 11 auf Höhe der Durchlauflinie 8 verläßt.If the bridle unit is to be operated in the bridle mode according to FIG. 2b, it remains the roll gap near roller 11 in its initial position 12 at the level of fixed Rollers 5. The arranged on a support frame 14 rollers 3 moves a hydraulic cylinder 15 from the home position 16 in the direction of Top of the band 4, so that the band 4 by the rollers 3, 5, 11 alternately bent and the roll gap near roll 11 at the level of the pass line. 8 leaves.

    Um die Oberseite des Bandes 4 zu colorieren, werden die Rollen 3 sowie die walzspaltnahe Rolle 11 jeweils in ihre Ausgangsposition 13, 16 gebracht und das Band auf die beiden festen Rollen 5 aufgelegt. Anschließend werden die Rollen 3 entsprechend Figur 3b auf die Oberseite des Bandes 4 zur Erzeugung einer Wechselbiegung abgesenkt. Die als Colorrolle wirkende Rolle 11 wird gegenüber den Rollen 3 noch etwas weiter abgesenkt, um einen von der Durchlauflinie 8 verschiedenen Einlaufwinkel des Bandes in den Walzspalt 9 einzustellen.To color the top of the tape 4, the rollers 3 and the roller gap near roller 11 each brought to their original position 13, 16 and the tape is placed on the two fixed rollers 5. Subsequently, the Rolls 3 according to Figure 3b on the top of the belt 4 to produce lowered a bending change. The roller role acting as Colorrolle 11 is opposite the rollers 3 lowered a little further to one of the pass line 8 different inlet angle of the belt in the nip 9 set.

    Um die Unterseite des Bandes 4 zu colorieren, werden die Rollen 3 in ihre Ausgangsposition 16 sowie die walzspaltnahe Rolle 11 in ihre Ausgangsposition 12 gebracht und das Band auf die beiden festen Rollen 5 und die walzspaltnahe Rolle 11 aufgelegt. Anschließend werden die Rollen 3 entsprechend Figur 4b auf die Oberseite des Bandes 4 zur Erzeugung einer Wechselbiegung abgesenkt. Die als Colorrolle wirkende walzspaltnahe Rolle 11 wird gegenüber den festen Rollen 5 etwas angehoben, um einen von der Durchlauflinie 8 verschiedenen Einlaufwinkel des Bandes in den Walzspalt 9 einzustellen.To color the underside of the band 4, the rollers 3 are in their starting position 16 and the roll gap near roll 11 in its starting position 12th brought and the tape on the two fixed rollers 5 and the roll gap near Roll 11 launched. Subsequently, the rollers 3 according to Figure 4b lowered to the top of the belt 4 to produce a reciprocal bend. The roller roll 11, which acts as a roller for rolls, is opposite to the roller roll 11 which acts as a roller fixed rollers 5 slightly raised to one different from the pass line 8 Adjustment angle of the belt in the nip 9 set.

    Um den Einlaufwinkel beispielsweise an unterschiedliche Banddicken, Bandgeschwindigkeiten oder Bandmaterialien stufenlos anpassen zu können, ist die walzspaltnahe Rolle 11 in beliebige Zwischenpositionen zwischen den Ausgangspositionen 12 und 13 mittels eines Hydraulikzylinders 18 verstellbar. Die Kolbenstange 19 des Hydraulikzylinders 18 greift an einem in einer Vertikalführung 21 verschieblich geführten Traggerüst 22 an. Das rechtwinklig ausgebildete Traggerüst 22 ermöglicht eine Anordnung des Hydraulikzylinders 18 unmittelbar neben dem Hydraulikzylinders 15 für die oberhalb des Bandlaufs angeordneten, verstellbaren Rollen 3 der Bridleeinheit 2. Die räumlich nahe Anordnung der Hydraulikzylinder 15, 18 in Verbindung mit dem abgewinkelten Traggerüst 22 ermöglicht einen geringeren Abstand zu dem Walzgerüst 1, als eine gerade Ausführung des Traggerüsts in geradliniger Verlängerung der Kolbenstange 19 des Hydraulikzylinders 18.To the inlet angle, for example, to different tape thicknesses, tape speeds or to be able to adjust strip materials steplessly is the roll gap near roll 11 in any intermediate positions between the starting positions 12 and 13 by means of a hydraulic cylinder 18 adjustable. The Piston rod 19 of the hydraulic cylinder 18 engages a in a vertical guide 21 slidably guided support frame 22 at. The right angle formed Shoring 22 allows an arrangement of the hydraulic cylinder 18 directly arranged next to the hydraulic cylinder 15 for the above the tape run, adjustable rollers 3 of the Bridle unit 2. The spatially close arrangement the hydraulic cylinder 15, 18 in conjunction with the angled Shoring 22 allows a smaller distance to the rolling mill 1, as a straight version of the shoring in straight extension of the piston rod 19 of the hydraulic cylinder 18th

    Die Ausführungsbeispiele verdeutlichen, daß die in Richtung der Durchlauflinie 8 im Achsabstand mit den übrigen Rollen übereinstimmende walzspaltnahe Rolle 11 durch die Entkopplung von den übrigen unterhalb des Bandlaufs angeordneten Rollen 5 die erfindungsgemäße Doppelfunktion ohne Nachteile für den Walzprozess erfüllt, insbesondere weil die Bauiänge der Bridleeinheit unverändert ist. Eine Verlängerung der Distanz zwischen dem Walzspalt 9 und der Abhaspelung ist daher mit der erfindungsgemäßen Bridleeinheit nicht verbunden. The embodiments illustrate that in the direction of the pass line 8 in the axial distance with the other roles matching roll gap near Roll 11 arranged by the decoupling of the rest below the tape run Rolls 5 the dual function of the invention without disadvantages for complies with the rolling process, in particular because the Bauiänge the Bridleeinheit unchanged is. An extension of the distance between the nip 9 and the Coiling is therefore not associated with the Bridleeinheit invention.
