Description

Die Erfindung betriffte eine Anlage zum flexiblen und wirtschaftlichen Beizen und Kaltwalzen von Metallbändern, gemäß dem Oberbegriff des Patentanspruchs 1 und ein Arbeitsverfahren gemäß dem Oberbegriff des Patentanspruchs 4.The invention relates to a system for flexible and economical pickling and Cold rolling of metal strips, according to the preamble of claim 1 and a working method according to the preamble of claim 4.

Es ist bekannt, Metallbeizen und Walzwerke zu koppeln und als sogenannte Endloswalzwerke zu betreiben. Solche Walzwerksanordnungen haben durch den Fortfall des diskontinuierlichen Einfädelbetriebes viele Vorteile und erbringen in der Regel sehr hohe Produktionsmengen je Zeiteinheit. Sie bedingen jedoch einen so hohen Investitionsaufwand, daß viele Betreiber von Anlagen für kleinere Produktionsmengen auch weiterhin in getrennte Metallbeizen und Walzwerksanlagen investieren.It is known to couple metal pickling and rolling mills and as so-called To operate endless rolling mills. Such mill arrangements have by Elimination of the discontinuous threading operation brings many advantages and bring in the Usually very high production quantities per unit of time. However, you condition one high investment that many operators of equipment for smaller Production volumes continue in separate metal pickling lines and rolling mill plants invest.

Um trotzdem höhere Produktionszahlen zu erreichen, wurden mehrgerüstige Reversierwalzwerke und/oder die Schaffung von extrem großen Coils nur zwischen Metallbeize und Walzwerk angedacht, welche hinter dem Walzwerk wieder umgewickelt und zerteilt werden, damit sie überhaupt transportiert und weiterverarbeitet werden können (EP 0724919 A 2). Solche Anlagen erfordern für die Wickelmaschinen extrem groß dimensionierte Sonderkonstruktionen, welche den Kostenvorteil wieder zweifelhaft erscheinen lassen.
Beizanlagen mit Wendehaspeln zum Beizen und Kaltwalzen von Bändern sind darüberhinaus der US 3918282 sowie der JP-A-7-164008 zu entnehmen. Ferner beschreibt die DE-A-2251182 den Aufbau einer als Wendehaspel ausgebildeten Haspelvorrichtung, wobei jedem Haspeldom ein eigener Antrieb zugeordnet ist. In order to nevertheless achieve higher production numbers, multi-stand reversing rolling mills and / or the creation of extremely large coils only between metal pickling and rolling mills were considered, which are rewound and divided behind the rolling mill so that they can be transported and further processed at all (EP 0724919 A 2) , Such systems require extremely large special constructions for the winding machines, which again make the cost advantage appear doubtful.
Pickling plants with reversible reels for pickling and cold rolling of strips can also be found in US 3918282 and JP-A-7-164008. Furthermore, DE-A-2251182 describes the structure of a reel device designed as a reversible reel, with each reel dome being assigned its own drive.

Aufgabe der vorliegenden Erfindung ist es, eine Anlage und ein Verfahren zu schaffen, mit der bzw. dem ohne betriebsbedingtes Hinzufügen oder Weglassen von Anlagenteilen mit minimalem Investitions- und Personalaufwand unter Verwendung üblicher Coilgrößen und Maschinendimensionen ein höchst flexibler
Beiz-Walzbetrieb für kleinere und mittlere Produktionsmengen wirtschaftlich möglich wird.It is an object of the present invention to provide a system and a method with which a highly flexible system can be used without the operationally adding or deleting of system parts with minimal investment and personnel expenditure using conventional coil sizes and machine dimensions
Pickling and rolling operation for small and medium-sized production quantities is economically possible.

Gelöst wird diese Aufgabe mit einer Anlage mit den Merkmalen des Patentanspruchs 1.
Das Reversierwalzwerk kann als konventionelles Reversiergerüst oder als 2- bis 3-gerüstige Tandemgerüstgruppe mit beidseitig der Tandemgerüstgruppe angeordneten Reversierhaspeln ausgebildet sein. Sobald der Reversierhaspel des Reversiergerüstes das Band übernommen hat, ist der Haspeldom des Wendehaspels frei für ein neues von der Metallbeize kommendes Coil.This object is achieved with a system with the features of claim 1.
The reversing rolling mill can be designed as a conventional reversing stand or as a 2- to 3-stand tandem stand group with reversing reels arranged on both sides of the tandem stand group. As soon as the reversing reel of the reversing stand has taken over the strip, the reel dome of the reversible reel is free for a new coil coming from the metal pickling line.

Insbesondere wenn hohe Stichabnahmen gefordert sind, z.B. wenn in nur einem Durchgang gewalzt wird, ist es günstig, wenn das Kaltwalzwerk mit 6-high Gerüsten ausgeststattet ist, die eine höhere Verformung gestatten.Especially when high stitch decreases are required, e.g. if in just one Continuity is rolled, it is beneficial if the cold rolling mill with 6-high stands is equipped, which allow a higher deformation.

Zur Lösung der Aufgabe wird ferner unter Verwendung der vorgenannten Anlage, bestehend aus in einer Linie angeordneter Metallbeize, einer aufwickelseitig der Metallbeize vorgesehenen Haspelanordnung und einem Kaltwalzwerk ein Arbeitsverfahren vorgeschlagen, das durch verschiedene alternativ abfolgende Arbeitsschritte gekennzeichnet ist, nämlich:

  • a. das die Metallbeize verlassende Band wird unter Umgehung der Haspelanordnung zu einem ersten Walzstich in das Kaltwalzwerk eingeführt und in mehreren Verformungsstichen ausgewalzt,
       oder
  • b. das die Metallbeize verlassende Band wird auf der Haspelanordnung zu einem Coil aufgewickelt, das nach dem Umsetzen in die Abwickelposition in das Kaltwalzwerk eingeführt und in mehreren Verformungsstichen gewalzt wird,
       oder
  • c. das die Metallbeize verlassende Band wird als Warmband auf der Haspelanordnung zu Fertigband aufgewickelt
       oder
  • d. vorgebeizte Warmbänder werden der Haspelanordnung zugeführt und aus der Abwickelposition in das Kaltwalzwerk eingeführt und in mehreren Verformungsstichen gewalzt.
    • In order to achieve the object, a working method is proposed using the above-mentioned system consisting of metal pickling arranged in a line, a reel arrangement provided on the winding side of the metal pickling and a cold rolling mill, which is characterized by various alternate working steps, namely:
  • a. the strip leaving the metal pickling is introduced into the cold rolling mill for a first pass, bypassing the reel arrangement, and rolled out in several deformation passes,
    or
  • b. the strip leaving the metal pickling line is wound up on the reel arrangement to form a coil which, after being converted into the unwinding position, is introduced into the cold rolling mill and rolled in a plurality of deformation passes,
    or
  • c. the strip leaving the metal pickling is wound up as a hot strip on the reel arrangement to form finished strip
    or
  • d. Pre-pickled hot strips are fed to the reel arrangement and introduced into the cold rolling mill from the unwinding position and rolled in several forming passes.

    • Konsequent wird bei der erfindungsgemäß vorgeschlagenen Lösung eine sogenannte "Teilverkopplung" von Beize und Walzwerk so vorgenommen, daß alle drei Betriebsarten - Endloswalzen, Teilverkopplung und diskontinuierlicher Betrieb - gleichermaßen auf ein und derselben Anlage möglich sind.The so-called solution in the solution proposed according to the invention is consequent "Partial coupling" made of pickling and rolling mill so that all three Operating modes - endless rolling, partial coupling and discontinuous operation - are equally possible on the same system.

    Vorzugsweise ist nach einer Ausgestaltung der Erfindung vorgesehen, daß das Kaltwalzen auf einem Reversierwalzwerk erfolgt, in das das nach den Arbeitsschritten a, b oder d hergestellte Band eingeführt und in mehreren Reversierstichen ausgewalzt wird, wobei das Band nach einem oder mehreren Reversierstichen auf mindestens einem der beidseitig des Reversierwalzwerks angeordneten Reversierhaspel aufgewickelt wird.It is preferably provided according to an embodiment of the invention that the Cold rolling takes place on a reversing rolling mill, in which after the work steps a, b or d is produced and rolled out in several reversing stitches is, the band after one or more reversing stitches to at least one of the reversing reels arranged on both sides of the reversing rolling mill is wound up.

    Nach einem anderen Merkmal der Erfindung ist es auch sinnvoll möglich, daß das Kaltwalzen des nach den Arbeitsschritten a, b oder d hergestellte Bandes auf einer 2 oder 3-gerüstigen Tandemstraße erfolgt, auf der das Band in einem Durchgang ausgewalzt wird oder daß nach einer weiteren Altemative das Band nach einem oder mehreren Reversierstichen auf mindestens einem der beidseitig der Tandemstraße angeordneten Reversierhaspel aufgewickelt wird.According to another feature of the invention, it is also possible that the Cold rolling the strip produced according to steps a, b or d on a second or 3-stand tandem mill, on which the belt in one pass is rolled out or that according to another alternative, the tape after one or multiple reversing stitches on at least one of the two sides of the tandem mill arranged reversing reel is wound up.

    Eine erfindungsgemäße gestaltete Anlage zur Durchführung des Arbeitsverfahrens ist extrem variabel, kommt mit einem Minimum an Bedienungspersonal aus, benötigt wenig Platz, hat geringe Investitionskosten und zeigt ihre größte Wirtschaftlichkeit bei Verwendung von dünnem Warmband, wie es in zunehmendem Maße von Dünnbrammenanlagen oder Bandgießanlagen erzeugt wird. A system designed according to the invention for carrying out the working method is extremely variable, needs a minimum of operating personnel, needed little space, has low investment costs and shows its greatest economy Use of thin hot strip, as is increasingly being the case Thin slab plants or strip casting plants is produced.

    Die Erfindung wird nachfolgend anhand einer schematisch dargestellten erfindungsgemäßen Anlage erläutert.The invention is illustrated below with the aid of a diagram Plant according to the invention explained.

    Das von einen Abwickelhaspel 1 abgewickelte Band B wird nach üblicher Vorbereitung über den Treibrollensatz 2 der als Schubbeize ausgebildeten Metallbeize 3 zur Bearbeitung zugeleitet. Die Metallbeize 3 wird ausgangsseitig hinter den herkömmlichen Adjustageeinrichtungen 4 wie Wäscher, Schrottschere und Teilschere mit einem horizontalen Wendehaspel 5 ausgerüstet, auf den das die Beize verlassende Band B aufgewickelt wird. Der Wendehaspel 5 hat einen Aufwickelhaspeldom 6 und einen Abwickelhaspeldom 7 mit getrennten Antrieben, d.h., jeder Haspeldom hat seine eigene Antriebseinheit, welche beim Wenden vorzugsweise abgekoppelt wird. Abwickelhaspeldom und Aufwickelhaspeldom sind im Gehäuse axial verschiebbar angeordnet, damit jeweils der der Metallbeize 3 abgewandte Abwickelhaspeldom 7 die hinter der Metallbeize 3 aufgewickelten Coils 8 mittig zu dem nachfolgenden Reversierwalzwerk 9 geregelt wieder abwickeln kann.The tape B unwound from a decoiler 1 is prepared in the usual way via the driving roller set 2 of the metal pickling 3 designed as thrust pickling Processing forwarded. The metal stain 3 is on the output side behind the conventional finishing devices 4 such as scrubbers, scrap shears and partial shears equipped with a horizontal reel 5 on which the stain leaving band B is wound up. The reversible reel 5 has one Take-up reel dome 6 and an unwind reel dome 7 with separate drives, i.e., each reel dome has its own drive unit, which is preferred when turning is uncoupled. Decoiler and decoiler are axial in the housing slidably arranged so that each of the metal pickle 3 facing away Decoiler 7 the coils 8 wound behind the metal pickle 3 in the middle of the subsequent reversing mill 9 can handle regulated again.

    Das Reversierwalzwerk 9 besteht aus einem traditionellen Reversiergerüst, welches das Coil 8 nach dem ersten Reduzierstich auf den Reversierhaspel 10 übernimmt. Der Abwickelhaspeldom 7 des Wendehaspels 5 ist dann frei für den Tausch mit dem Aufwickelhaspeldom 6 und steht der Metallbeize 3 wieder zur Verfügung.The reversing mill 9 consists of a traditional reversing stand, which the coil 8 takes over the reversing reel 10 after the first reducing stitch. The Unwinding reel dome 7 of the reversible reel 5 is then free for exchange with the Winding reel dome 6 and the metal pickle 3 is available again.

    Das Reversiergerüst 9 kann, wie in der unteren Zeichnungshälfte dargestellt, auch eine 2- bis 3-gerüstige Tandemstraße mir den Gerüsten 9a und 9b sein. Diese sind vorzugsweise in 6-high-Bauweise (die relativ kleinen Arbeitswalzen sind über Zwischenwalzen und Stützwalzen augestützt) für hohe Reduktionen (über 50 % im ersten Gerüst) ausgelegt, so daß sich ein Teil der gebeizten Bänder B in einem Durchgang walzen lassen. In diesem Fall ist -wie dargestellt - ein "Überfahren" des Wendehaspels 5 im sogenannten Endlosbetrieb möglich.The reversing frame 9 can, as shown in the lower half of the drawing a 2 to 3-stand tandem mill with stands 9a and 9b. These are preferably in 6-high construction (the relatively small work rolls are over Intermediate rolls and back-up rolls supported) for high reductions (over 50% in first scaffold) designed so that part of the pickled strips B in one Let the passage roll. In this case, as shown, the vehicle is "run over" Reversible reel 5 possible in so-called endless operation.

    Werden mehrere Durchgänge im Reversierwalzwerk benötigt, kann die Metallbeize 3 in den entstehenden Pausen ohne weiteres sogenannte nicht kaltgewalzte P.0. Coils erstellen. Das Band B wird in diesem Fall hinter der Metallbeize 3 auf dem Aufwickelhaspeldom 6 des Wendehaspels 5 aufgewickelt und als Fertigprodukt abgeben. Solche P.0. Coils können natürlich auch in längeren Pausen des Reversierwalzwerkes 9, etwa bei Stützwalzenwechsel, gebeizt werden.If several passes are required in the reversing rolling mill, the metal pickle 3 in the resulting breaks, so-called non-cold-rolled P.0. coils create. The band B is in this case behind the metal pickle 3 on the Wind-up reel dome 6 of the reversible reel 5 and wound as a finished product submit. Such P.0. Of course, coils can also be used during longer breaks Reversing roll mill 9, for example when changing the backup roll, are pickled.

    Die Flexibilität der Anlage ermöglicht es auch, bei geplanten Stillständen in der Metallbeize 3 vorher auf Vorrat gebeizte Coils 8 im Reversierwalzwerk 9 auszuwalzen. Diese Coils 8 werden dem Abwickelhaspeldom 7 des Wendehaspels 5 zugeführt und dort abgewickelt dem Reversierwalzwerk 9 zugeleitet.The flexibility of the system also makes it possible to plan planned shutdowns in the Roll out metal pickling 3 coils 8 previously pickled in the reversing mill 9. These coils 8 are fed to the decoiler 7 of the turning reel 5 and handled there, fed to the reversing mill 9.
