Abstract
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
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
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
Erläutert wird die Erfindung anhand der Beschreibung von in Zeichnungen dargestellten Ausführungsbeispielen. Es zeigen hierbei:

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
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
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
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
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
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
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
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

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
Der Schwenkarm 23 mit der Niederhalterrolle 24 ist in Fig. 3 über den Hydraulikzylinder
25 außer Wirkstellung gebracht.The
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
