Abstract

The invention relates to a hot rolling mill, with at least one flatness measuring roller, pertaining to at least one rolling bed, arranged before and/or after one of the stands, which influences the settings of at least one of the stands. The aim of the invention is to improve the arrangement of the roller bed working rollers and the flatness measuring roller, such that the flatness measuring roller may be, optionally, either brought into operation, or be withdrawn into a protected position, whereby, in this case, the gap in the rolling bed thus formed can be closed. Said aim is achieved, whereby the flatness measuring roller may be stored, away from its working position, behind a screen and that the rolling bed is completed with at least one retractable working roller.

Description

Die Erfindung betrifft ein Warmwalzwerk mit einer mindestens einem der Gerüste vor- und/oder nachgeordnetem Rollgang zugeordneten, Anstellungen von mindestens einem der Gerüste beeinflussenden Planheitsmeßrolle.The invention relates to a hot rolling mill with at least one of Scaffolding before and / or subordinate roller table assigned, jobs at least one of the frameworks influencing planarity measuring roll.

Bei Kaltwalzwerken ist es bekannt, Planheitsmeßrollen einzusetzen, die zur Erzielung spannungsfreien Walzbandes An- bzw. Einstellungen von Gerüsten beeinflussen, so beispielsweise ungleiche Walzkräfte für die Ständer eines Gerüstes bewirken können und/oder korrigierende Biegekräfte erwirken. Bei modemen Warmwalzverfahren werden Bänder < 1,0 mm Dicke gewalzt, so daß auch hier der Einsatz von Planheitsmeßrollen angebracht wäre. Bisher wurde von deren Einsatz in Warmwalzwerken jedoch abgesehen, da sie einerseits relativ empfindlich sind, und andererseits der Einsatz in einer Warmwalzstraße die Planheitsmeßrolle nicht nur hohen Temperaturen aussetzt, sondern auch Kühlwasser und die damit bedingten hohen Temperaturgradienten die Rolle extrem belasten. Auch das hohe Aufkommen von Zunder beansprucht die Planheitsmeßrolle außerordentlich und verringert deren Standzeit.In cold rolling mills, it is known to use flatness measuring rolls, the to achieve tension-free rolled strip on or settings of Frameworks influence, such as unequal rolling forces for the Can effect stand of a scaffold and / or corrective bending forces obtain. In modem hot rolling process bands <1.0 mm rolled thickness, so that also here the use of Planheitsmeßrollen would be appropriate. So far, their use has been in hot rolling mills however, apart from being relatively sensitive on the one hand and on the other hand the use in a hot rolling line not only the flatness measuring roll high temperatures, but also cooling water and the so conditional high temperature gradient, the roller extremely burden. Also The high amount of scale is extremely demanding on the flatness measuring roll and reduces their service life.

Die DE-A-37 21 746 offenbart zwar eine verschwenkbare Planheitsmessrolle, diese ist jedoch, wenn sie außer Betriebsstellung gefahren ist, nicht besonders geschützt. Kühlwasser, Zunder und andere Verunreinigungen können ungehindert auf die Planheitsmessrolle gelangen, zumal im abgesenkten Zustand der Planheitsmessrolle über ebenfalls abgesenkte Leitbleche die Verunreinigungen direkt auf die Planheitsmessrolle geleitet werden.Although DE-A-37 21 746 discloses a pivotable flatness measuring roller, however, this is not when it has gone out of service specially protected. Cooling water, scale and other impurities can pass unhindered on the flatness measuring roller, especially in the lowered Condition of the flatness measuring roll over also lowered baffles the impurities are passed directly to the flatness measuring roller become.

Durch die DE-A-1 427 863 oder die DE-C-151 125 sind zwar verschwenkbare Rollgangsrollen bekannt, eine Anregung hier anstelle der Rollgangsrollen Planheitsmessrollen einzusetzen und diese besonders zu schützen, wird jedoch nicht gegeben.By DE-A-1 427 863 or DE-C-151 125 are indeed pivotable Roller table rollers known, a suggestion here instead of the roller table rollers To use flatness measuring rolls and to protect them especially is not given.

Die Erfindung geht von der Aufgabe aus, eine Planheitsmeßrolle für Warmwalzwerke so zu gestalten, daß sie besonders gegen die Umgebungseinflüsse geschützt ist. The invention is based on the task of a Planheitsmeßrolle for Hot rolling mills to be designed so that they are particularly resistant to environmental influences is protected.

Die Lösung der Aufgabe ist mit den Merkmalen des Patentanspruches 1 gegeben. Sie erlauben es, entweder unter Ausfahren mindestens einer Rollgangsrolle die Planheitsmeßrolle in die entstandene Lücke mit ihrer obersten Mantellinie definiert über die Auflageebene des Rollganges vorzuschieben und danach eine Niederhalterrolle abzusenken, oder aber die Planheitsmeßrolle nach unten abzusenken und die im Rollgang entstandene Lücke durch eine Rollgangsrolle zu schließen.The solution of the problem is with the features of claim 1 given. They allow it, either by extending at least one Roll roller the flatness measuring roll in the resulting gap with their Defined top coat line defined to advance over the support plane of the roller table and then lower a hold-down roller, or the Lower planarity measuring roll down and the resulting in the roller table Gap to close by a roller table role.

Dabei kann, wie der Anspruch 2 vorschlägt, die Planheitsmeßrolle sowie die Rollgangsrolle in einer um eine Achse antreibbar drehbaren Box derart angeordnet sein, daß die Planheitsmeßrolle und die Rollgangsrolle durch Drehen vorzugsweise im gleichen Sinne alternativ in Arbeitsstellung führbar sind. Es besteht aber auch die Möglichkeit, wie Anspruch 9 vorschlägt, die Planheitsmeßrolle sowie die mindestens eine Rollgangsrolle in einer um eine Achse verschwenkbaren Box derart anzuordnen, daß die Planheitsmeßrolle und die Rollgangsrollen durch Auf- und Abschwenken alternativ in Arbeitsstellung führbar sind.In this case, as the claim 2 proposes the Planheitsmeßrolle and the roller table role in a drivable about an axis rotatable box such be arranged that the flatness measuring roll and the roller table role Turning preferably in the same sense alternatively feasible in working position are. However, it is also possible, as claim 9 suggests, the flatness measuring roll and the at least one roller table roller in one to arrange pivotable about an axis box such that the Planheitsmeßrolle and the roller table rollers by swinging up and down alternatively in work position are feasible.

Vorteilhafte und weiterbildende Merkmale der Erfindung sind den Ansprüchen 3 bis 8 sowie 10 bis 20 entnehmbar.Advantageous and further developing features of the invention are the claims 3 to 8 and 10 to 20 removed.

The invention will be explained with reference to the description of exemplary embodiments illustrated in drawings. It show here:
FIG. 1
schematically the arrangement of each stored in a rotatable box flatness measuring roll and roller table roller,
FIG. 2
a section of a roller table of a hot rolling mill with the planarity measuring roller and roller table roller containing rotatable box and a lowerable Niederhalterolle,
FIG. 3
a swiveling box containing a section of a roller table of a hot rolling mill with a planarity measuring roller, wherein the flatness measuring roller is brought out of operative position,
FIG. 4
a representation according to FIG. 3, but in which the planarity measuring roller is brought into operative position, and
FIG. 5
the longitudinal section through a box according to fig. 3 or 4 with flatness measuring roller and roller table roller including drives.

In der Figur 1 sind zwei Kreisscheiben 1 und 2 dargestellt, die durch eine Schirmplatte 3 zu einer Box 4 verbunden sind. Linksseitig ist die Box 4 mittels eines Zapfens 5 drehbar in einem Lager 6 gehalten. Rechtsseitig weist sie einen Zapfen 7 auf, der in einem Drehzapfen 8 gelagert ist, der seinerseits in einem Lager 9 gehalten wird und das Lager 10 des Zapfens 7 umschließende Stimräder 11 und 12 trägt.In the figure 1, two circular disks 1 and 2 are shown, which by a Shade plate 3 are connected to a box 4. On the left side is the box 4 held rotatably in a bearing 6 by means of a pin 5. Dexter it has a pin 7 which is mounted in a pivot 8, the in turn is held in a bearing 9 and the bearing 10 of the pin 7 enclosing sprockets 11 and 12 carries.

Stirnrad 11 kämmt mit dem Zahnrad 13, dass drehfest auf dem Antriebszapfen der Rollgangsrolle 14 angeordnet ist. Das Stirnrad 12 kämmt mit dem Zahnrad 15, das drehfest auf einem der Wellenzapfen der Planheitsmeßrolle 16 vorgesehen ist. Die Rollgangsrolle 14 sowie die Planheitsmeßrolle 16 sind in Lagern der Kreisscheiben 1 und 2 der Box 4 gehalten. Damit ergeben sich folgende Möglichkeiten: zur Umstellung von wirksamer Planheitsmeßrolle 16 auf wirksame Rollgangsrolle 14 wird durch einen nicht dargestellten Antrieb der Zapfen 5 im Sinne des Pfeiles 17 angetrieben, bis die Box 4 sich um ihre durch Zapfen 5 und 7 gegebene Drehachse um 180° gedreht hat. Diese Drehung kann durch elektromechanische oder elektronische, die Drehung überwachende Geber begrenzt werden, es ist aber auch möglich, beispielsweise die Kreisscheibe 1 mit zwei als Absätze oder Einschnitte ausgebildete Rasten 18 auszustatten und die Scheibe gegen einen ihren Umfang abtastenden und vor der Rast 18 sich einlegenden, nicht dargestellte Lasche zum Stehen zu bringen und in dieser Stellung zu halten bzw. ggf. zu verriegeln.Spur gear 11 meshes with the gear 13 that rotatably on the drive pin the roller table roller 14 is arranged. The spur gear 12 meshes with the gear 15, the rotationally fixed on one of the shaft journal of the Planheitsmeßrolle 16 is provided. The roller table roller 14 and the Planheitsmeßrolle 16 are held in bearings of the circular discs 1 and 2 of the box 4. This results in the following options: for the conversion of effective Planheitsmeßrolle 16 on effective roller table roller 14 is by a drive, not shown, the pin 5 in the direction of the arrow 17 driven until the box 4 is given to her by pins 5 and 7 Rotated axis has rotated 180 °. This rotation can be through electromechanical or electronic, the rotation monitoring encoder limited be, but it is also possible, for example, the circular disk 1 equipped with two trained as paragraphs or incisions detents 18 and the disc against a her scanning and before the catch 18 is inserted, not shown, tab to stand bring and hold in this position or lock if necessary.

Zweckmäßig kontinuierlich während des Betriebes wird durch ebenfalls nicht dargestellte Antriebsmittel der Drehzapfen 8 im Sinne des Drehpfeils 19 angetrieben. Er nimmt hierbei die Stimräder 11 und 12 mit, die ggf. auch einstückig oder einstückig mit ihm hergestellt sein können, und treibt damit über die Zahnräder 13 und 15 sowohl die Rollgangsrolle 14 als auch die Planheitsmeßrolle 16 an, so daß, wenn eine derselben in Wirkstellung gebracht wird, sie bereits mit der Vorschubgeschwindigkeit des Walzbandes als Umfangsgeschwindigkeit rotiert.Expediently, continuously during operation is by also not shown drive means of the pivot 8 in the sense of the rotary arrow 19 driven. He takes here the spokes 11 and 12, which possibly can also be made in one piece or in one piece with it, and drives thus on the gears 13 and 15 both the roller table roller 14 and the Planheitsmeßrolle 16, so that when one of them in operative position is brought, they already at the feed rate of the rolled strip rotated as peripheral speed.

Wesentlich ist noch, daß der Abstand der Lager der Rollgangsrolle 14 von der Drehachse der Box 4 so gewählt ist, dass beim Einschwenken der Rollgangsrolle 14 deren jeweils oberste Mantellinie mit den oberen Mantellinien der übrigen Rollgangsrollen fluchtet, während die üblicherweise mit größerem Durchmesser ausgeführte Planheitsmeßrolle 16 in Wirkstellung mit ihrer obersten Mantellinie oberhalb der Ebene der oberen Mantellinien des Rollganges steht.It is essential that the distance between the bearings of the roller table roller 14 of the axis of rotation of the box 4 is chosen so that when swinging the Roller table roller 14 whose uppermost surface line with the upper generatrices the other roller table rollers are aligned, while the usual Planarity measuring roller 16 with a larger diameter is in operative position with its uppermost generatrix above the level of the upper generatrices the roller table stands.

Eine Eingliederung der Box in einen Abschnitt eines Warmwalzwerkes zeigt Fig. 2. Hier ist der Rollang 20 dargestellt, aus dem die Rollgangsrolle 14 in Pfeilrichtung 21 nach unten ausgeschwenkt und dafür die Planheitsmeßrolle 16 eingeschwenkt ist. Nach entsprechendem Einlauf des Warmwalzbandes 22 wird die am freien Ende des Schwenkarmes 23 gelagerte Niederhalterolle 24 mittels des Hydraulikzylinders 25 abgesenkt. Schon vorher war der Schwenkarm 23 mit Druckluft beaufschlagt, die aus Schlitzen von Leitblechen 26 als durch Pfeile 27 gekennzeichnete Luftströmung nach unten austritt und das Warmwalzband 22 gegen die Planheitsmeßrolle 16 und den Rollgang 20 anpresst, eine Maßnahme, die bei dünnen Warmbändern sich als notwendig erweist. Nach Herabschwenken der Niederhalterolle 24 aus der in Fig. 2 dargestellten angehobenen Lage in die strichpunktiert dargestellte Lage lässt sich der Schwenkwinkel zur Bestimmung der Dicke des Walzgutes benutzen.An integration of the box into a section of a hot rolling mill shows Fig. 2. Here, the roll 20 is shown, from which the roller table role 14 pivoted downward in the direction of arrow 21 and for the flatness measuring roll 16 is pivoted. After appropriate entry of the Hot roll strip 22 is mounted at the free end of the pivot arm 23 Hold-down roller 24 lowered by means of the hydraulic cylinder 25. Even before, the pivot arm 23 was subjected to compressed air, the off Slots of baffles 26 as indicated by arrows 27 air flow down the exit and the hot roll strip 22 against the Planheitsmeßrolle 16 and the roller table 20 presses, a measure at thin hot strips proves necessary. After swinging down the hold-down roller 24 from the raised position shown in Fig. 2 in the dot-dashed position can be the tilt angle to Determine the thickness of the rolling stock.

Bei dem dargestellten Ausführungsbeispiel hat es sich bewährt, daß das Einfahren der Rollgangsrolle 14 bzw. der Planheitsmeßrolle 16 so erfolgen, daß das Warmwalzband 22 tangential und damit unter Vermeidung übergroßer Kräfte angefahren wird, und da sowohl das Einfahren der Rollgangsrolle 14 als auch der Planheitsmeßrolle 16 mit gleicher Drehrichtung erfolgen wird in jedem dieser Fälle ein Vorschub etwa in Laufrichtung des Warmwalzbandes 22 erzielt.In the illustrated embodiment, it has been proven that the Retracting the roller table roller 14 or the Planheitsmeßrolle 16 carried out so that the hot strip 22 tangential and thus avoiding oversized forces, and because both the retraction of the Roller table roller 14 and the Planheitsmeßrolle 16 with the same direction of rotation in each of these cases, a feed is made approximately in the direction of travel achieved the hot roll strip 22.

Das Anliegen extrem dünnen Warmwalzbandes wird durch Luftströme wie ihn die Pfeile 27 zeigen unterstützt. Die Schirmplatte 3 schützt die jeweils rückgefahrene der Rollen vor Wasser, Zunder oder anderen Festteilen ebenso, wie vor starken Wasserstrahlen und großer Hitze, so daß der gewünschte Schutz erreicht ist. Hierbei läßt sich eine weitgehende Anpassung an den Walzprozeß durchführen: die Planheitsmeßrolle 16 wird zweckmäßig nach passieren des Bandanfanges in ihre Arbeitsposition gefahren, und anschließend wird die Niederhalterolle 24 derart abgesenkt, daß einerseits durch zu schnelles Absenken bedingte Beschädigungen dünnen Warmwalzbandes 22 vermieden werden, andererseits jedoch die Arbeitsstellung erreicht wird, wenn die folgenden, daß Band erfassenden Aggregate, im Allgemeinen ein Haspel, den Bandanfang fest aufgenommen haben und das Band damit bestimmungsgemäß gestrafft ist.The concern of extremely thin hot strip is caused by air currents such as supporting him with arrows 27. The shield plate 3 protects each Rewind the rollers from water, scale or other hard particles as well as strong jets of water and high heat, so that the desired Protection is achieved. This can be a far-reaching adaptation to perform the rolling process: the flatness measuring roll 16 is Appropriately after passing the beginning of the tape in their working position driven, and then the hold-down roller 24 is lowered so, on the one hand due to too rapid lowering caused damage thin hot rolled strip 22 are avoided, on the other hand, however Working position is achieved when the following, that tape capturing Aggregates, generally a reel, the beginning of the tape firmly recorded have and the tape is streamlined as intended.

Die Steuerungsvorgänge erfolgen zweckmäßig wie bereits vom Einsatz der Planheitsmeßrolle bei Kaltwalzwerken bekannt. The control operations are carried out appropriately as already from the application the flatness measuring roll in cold rolling mills known.

Es kann sich bewähren, die Box 4 nicht nur mit der Schirmplatte 3 auszustatten, sondern mit weiteren, in der zurückgezogenen Stellung die Planheitsmeßrolle abdeckenden und schützenden Einbauten zu versehen.
Die Fig. 3 zeigt einen ähnlichen Ausschnitt eines Warmwalzwerks wie Fig. 2. Hier ist jedoch die drehbare Box 4 durch eine schwenkbare Box 4' ausgetauscht. Die Box 4' ist um einen Drehpunkt 28 verschwenkbar. Als Verschwenkantrieb dient eine Kolben-Zylinder-Einheit 29, die exzentrisch an der Box 4' angreift.It may prove useful to equip the box 4 not only with the shield plate 3, but to provide with other, in the retracted position the Planheitsmeßrolle covering and protective internals.
Fig. 3 shows a similar section of a hot rolling mill as shown in FIG. 2. Here, however, the rotatable box 4 is replaced by a pivoting box 4 '. The box 4 'is pivotable about a pivot point 28. The pivoting drive is a piston-cylinder unit 29 which acts eccentrically on the box 4 '.

Die Box 4' weist Rollgangsrollen 14' sowie eine Planheitsmeßrolle 16' auf. Die Planheitsmeßrolle 16' ist aus der Auflageebene des Rollganges 20' ausgeschwenkt. Die Rollgangsrollen 14' schließen die hier entstandene Lücke. Weiterhin sind Schutzeinrichtungen 30 bis 33 gezeigt, die als Bandleittische ausgebildet sind. Die Schutzeinrichtungen 30 bis 33 bewirken, daß insbesondere Zunder und verschmutztes Kühlwasser von der Planheitsmeßrolle 16' ferngehalten werden.The box 4 'has roller table rollers 14' and a Planheitsmeßrolle 16 '. The Planheitsmeßrolle 16 'is from the support plane of the roller table 20' swung. The roller table rollers 14 'close the resulting here Gap. Furthermore, protective devices 30 to 33 are shown as Tape slide tables are formed. The protective devices 30 to 33 cause that in particular scale and polluted cooling water from the Planheitsmeßrolle 16 'are kept away.

Der Schwenkarm 23 mit der Niederhalterrolle 24 ist in Fig. 3 über den Hydraulikzylinder 25 außer Wirkstellung gebracht.The pivot arm 23 with the hold-down roller 24 is in Fig. 3 via the hydraulic cylinder 25 brought out of action.

Figur 4 zeigt, daß die Box 4' durch die Kolben-Zylinder-Einheit 29 positionsgeregelt verschwenkt wurde. Nicht gezeigte Anschläge sowie ebenfalls nicht gezeigte Arretiermittel können die Box 4' in Wirkstellung halten, in der die Planheitsmeßrolle 16' über die Auflageebene des Rollganges 20' hinaus nach oben verschwenkt wurde. Die Niederhalterrolle 24 sorgt für eine ausreichende Umschlingung der Planheitsmeßrolle 16'. Die Planheitsmeßrolle 16' kann über Kühlvorrichtungen 34 sowie Abblasvorrichtungen 35 gereinigt und gekühlt werden. FIG. 4 shows that the box 4 'is position-controlled by the piston-cylinder unit 29 was pivoted. Not shown attacks as well Not shown locking means can keep the box 4 'in operative position, in the flatness measuring roll 16 'over the supporting plane of the roller table 20' has been pivoted upwards. The hold-down roller 24 ensures sufficient wrap around the flatness measuring roll 16 '. The flatness measuring roll 16 'may have cooling devices 34 as well as blow-off devices 35 are cleaned and cooled.

Figur 5 zeigt die Box 4', welche um die Zapfen 36 verschwenkbar sind. Die Rollgangsrollen 14' sowie die Planheitsmeßrolle 16' werden über getrennte Antriebe 37, 37' und entsprechende Spindeln 38, 38' angetrieben. Figure 5 shows the box 4 ', which are pivotable about the pins 36. The Roller conveyor rollers 14 'and the flatness measuring roller 16' are separated Drives 37, 37 'and corresponding spindles 38, 38' driven.
