Abstract

In a process of hot dip coating of metal strips, in particular, of a hot rolled steel strip, in which the metal strip is transformed into a continuous strip in an unwinding station with an adjoining welding machine, and then the continuous strip is subjected to a downstream modifying process including primary and secondary prickling and, in the final treatment step; in the hot dip coating section, guiding the continuous strip through a melt bath, a variable coating process with reduced costs becomes possible when the continuous strip, in a first treatment step, is directly transported into a pickling installation. In a suitable installation for effecting the process, the primary pickling installation is located in the entry section which is separated from the hot dip coating section by an entry accumulator.

Description

Die Erfindung betrifft ein Verfahren und eine Anlage zum Feuerbeschichten von metallischen Bändern, bei dem das Metallband in einer Abwickelstation mit sich anschließender Schweißmaschine zunächst in ein Endlosband überführt und das Endlosband dann einem nachgeschalteten Veredelungsprozess unterworfen wird, der eine Haupt- sowie eine Nachbeize und in einem letzten Behandlungsschritt im Feuerbeschichtungsteil das Hindurchführen des Endlosbandes durch ein Schmelzbad vorsieht.The invention relates to a method and a system for the hot coating of metallic strips, in which the metal strip is in an unwinding station subsequent welding machine first transferred to an endless belt and the endless belt is then subjected to a subsequent finishing process which is a main and a subsequent pickling and in a final treatment step in the fire-coating part, the passing of the endless belt through a weld pool.

Zum Feuerbeschichten von Warmband, aber auch von walzhartem und/oder vorgeglühtem Kaltband, ist es bekannt, das Bandcoil mittels einer bspw. eine Doppel- oder Wendehaspel mit sich anschließender Schweißmaschine umfassenden Abwickelstation durch Verschweißen des jeweiligen Coilendes mit dem Anfang eines Folgecoils in ein Endlosband zu überführen bzw. ein solches Endlosband bereitzustellen. Der Abwickelstation schließt sich ein den nachfolgenden kontinuierlichen Behandlungsprozess sicherstellender, in vertikaler oder horizontaler Bauweise ausgeführter Schlingenspeicher an. In diesem wird somit verzundertes Band bevorratet, wobei ein nicht unerheblicher Anteil an Staub anfällt. Der Speicher muss daher gekapselt werden. Nach dem Schlingenspeicher wird das Band in einem ersten Verfahrensschritt durch eine Streckbiegerichtmaschine gezogen, um die gewünschte Planlage des Bandes zu erreichen. Bei diesem Prozess erfolgen zwangsläufig ein Ausbrechen und teilweises Abplatzen der Zunderschicht. Dies erfordert es, dass die abfallenden Zunderpartikel gesondert abgesaugt und gefiltert werden müssen. Hinzu kommt weiterhin, dass die Rollenlager der Streckbiegerichtmaschine gegen den Anfall der feinsten Zunderpartikel aufwendig geschützt werden müssen, wozu die Streckbiegerichtmaschine insgesamt selbst gekapselt wird. For hot-coating hot strip, but also hard-rolled and / or pre-annealed cold strip, it is known to use a strip coil, for example Comprehensive double or reversible reel with subsequent welding machine Unwinding station by welding the respective coil end to the To convert the beginning of a follow-up coil into an endless belt or one To provide endless belt. The unwind station includes the following ensuring continuous treatment process, in vertical or horizontal construction of sling storage. In this is thus scaled tape stocked, with a not inconsiderable proportion of dust accrues. The memory must therefore be encapsulated. After the sling store in a first process step, the strip is processed by a stretch bending straightener pulled to achieve the desired flatness of the belt. This process inevitably causes a breakout and partial chipping the scale layer. This requires that the scaling particles fall off must be suctioned off and filtered separately. In addition, that the roller bearing of the stretch-leveling machine prevents the finest Scale particles need to be protected, which is why the stretch leveler is encapsulated overall.

Das aus der Streckbiegerichtmaschine auslaufende Band wird bei der bekannten Anlage in eine Beizstation eingeführt, wo die Zunderschicht sowie Reaktionsprodukte von der Bandoberfläche entfernt werden. In einem weiteren Verfahrensschritt durchläuft das Band anschließend eine Spülstation, um darin die Bandoberfläche von Rückständen der Beize und Beizprodukten freizuspülen, bevor es in eine Trockenstation eingeführt und darin getrocknet wird. Dieser Hauptbeize mit Spüle kann sich vor dem Trockner noch eine Nachbeize mit folgender Spüle anschließen. Aus dem Trockner wird das Band schließlich in einem weiteren Verfahrensschritt in einen Ofen eingeführt und darin unter Schutzgasatmosphäre auf Beschichtungstemperatur eingestellt, bevor es in einem letzten Verfahrensschritt durch ein Schmelzbad hindurchgeführt und dabei die Oberfläche des Bandes mit einem metallischen Überzug versehen wird.The strip running out of the stretch-leveling machine is used in the known Plant introduced into a pickling station where the scale layer as well as reaction products be removed from the belt surface. In a further process step the belt then passes through a rinsing station to insert the Rinse the belt surface from residues of the pickling and pickling products, before it is introduced into a drying station and dried in it. This Main stain with sink can have a subsequent stain in front of the dryer with the following Connect the sink. The dryer finally turns the belt into one another process step introduced into an oven and under Protective gas atmosphere set to coating temperature before it is in a final process step through a weld pool and thereby the surface of the tape is provided with a metallic coating.

Durch die EP-A 1 0863 222 sind ausgehend von einem warmgewalzten Band ein Verfahren und eine Anlage zum Herstellen eines kaltgewalzten, verzinkten Metallbandes bekanntgeworden, bei dem das Vorband zunächst gebeizt, dann kaltgewalzt und danach verzinkt wird. Das erfolgt kontinuierlich hintereinander, wozu der Kaltwalzprozess mit dem Beiz- und Verzinkungsprozess gekopppelt wird.EP-A 1 0863 222 is based on a hot-rolled strip a method and a plant for producing a cold-rolled, galvanized Metal strip became known, in which the supporting strip is first stained, then cold rolled and then galvanized. This is done continuously in a row, which is why the cold rolling process is coupled with the pickling and galvanizing process becomes.

Aus der GB-A 1 004 704 ist es bekannt, ein Metallband in einem kontinuierlichen Durchlauf mit Umlenkung über Rollen in einen vertikalen Behandlungsteil zu führen. Dort wird mit Schlingen im Metallband bildenden Tauchrollen die Speicherkapazität erhöht.From GB-A 1 004 704 it is known to use a metal strip in a continuous Pass with deflection via rollers into a vertical treatment section respectively. There, the slings are formed with loops in the metal belt Storage capacity increased.

Nach der EP-A 0 506 000 durchläuft ein Metallband horizontal und kontinuierlich zunächst eine Vorbeize und danach eine Hauptbeize.According to EP-A 0 506 000, a metal strip runs horizontally and continuously first a stain and then a main stain.

Bei einer aus der JP-A 55 006 436 bekannten Anlage wird ein Metallband mit verschiedenen Umlenkungen kontinuierlich durch die Anlagenteile hindurchgeführt. In a system known from JP-A 55 006 436, a metal strip is used various deflections continuously passed through the system parts.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Anlage der eingangs genannten Art zu schaffen, die mit verringertem Aufwand einen variableren Beschichtungsprozess ermöglicht.The invention has for its object a method and a system of to create the kind mentioned at the beginning, with less effort a more variable Coating process enables.

Diese Aufgabe wird mit einem Verfahren erfindungsgemäß mit den im kennzeichnenden Teil des unabhängigen Anspruchs 1 und für eine Anlage mit den im kennzeichnenden Teil des unabhängigen Anspruchs 2 angegebenen Merkmalen gelöst.This object is achieved with a method according to the invention in the characterizing Part of independent claim 1 and for an installation with the Features specified in the characterizing part of independent claim 2 solved.

Es lassen sich mehrere Vorteile gleichzeitig erreichen. So wird erreicht, dass in den nachfolgenden Anlagenkomponenten, wobei sich der Beize vorteilhaft eine Spülstation und eine Trockenstation anschließen, ein zunderfreies Metallband vorliegt, was eine Kapselung des Einlaufspeichers und der Streckbiegerichtmaschine entbehrlich macht. Die Streckbiegerichtmaschine kann einfach ausgeführt werden, weil eine aufwendige Zunderabsaugung entfallen kann. Durch die Entkopplung der Hauptbeize vom Feuerbeschichtungsprozess zieht ein kurzer Stillstand in der Beize nicht mehr wie bei dem bekannten Verfahren einen Stillstand der Feuerbeschichtung nach sich, der die Produktion von Schrott bedeuten würde. Umgekehrt würde ein kurzer Stillstand der Feuerbeschichtung nicht zu einer Überbeizung des Bandes in der Hauptbeize führen, weil der dieser nachgeschaltete Schlingenspeicher eine ausreichende Aufnahmekapazität besitzt. Außerdem wird der sich dem Beizprozess anschließende Speicher zunderfrei gehalten.Several advantages can be achieved at the same time. This ensures that in the subsequent system components, the pickling advantageously being a Connect the rinsing station and a drying station, a scale-free metal band is present, which is an encapsulation of the inlet storage and the stretch bending leveler dispensable. The stretch bending leveler can be carried out simply because there is no need for complex scale extraction. Through the Decoupling the main stain from the hot coating process takes a short Standstill in the pickle is no longer a standstill as in the known method the fire coating itself, which mean the production of scrap would. Conversely, a short downtime of the fire coating would not lead to over-pickling of the tape in the main pickling because of this downstream loop storage has sufficient absorption capacity. In addition, the storage following the pickling process becomes scale-free held.

Für den kombinierten Betrieb mit Warmband und Kaltband in den Zuständen walzhart oder vorgeglüht ergibt sich der Vorteil, dass beim Umstellen auf den Betrieb mit Kaltband keine vorherige Reinigung des Speichers, aller Rollen und der Streckbiegerichtmaschine erforderlich ist. Die Rüstzeiten werden damit minimiert und die Qualität des Bandes wird verbessert. For combined operation with hot strip and cold strip in the states Hard-rolled or pre-annealed has the advantage that when switching to the Operation with cold strip no prior cleaning of the memory, all rolls and the stretch leveler is required. This minimizes set-up times and the quality of the tape is improved.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Ansprüchen und der nachfolgenden Beschreibung eines in der Zeichnung dargestellten Ausführungsbeispiels der Erfindung.Further advantages and features of the invention result from the claims and the following description of one shown in the drawing Embodiment of the invention.

Die einzige Figur zeigt ein Anlagen-Schema zur Schmelztauchveredelung eines Metallbandes durch Feuerbeschichtung. Die Anlage besteht aus einem Einlaufteil I und einem Feuerbeschichtungsteil II, wobei diese beiden Teile voneinander entkoppelt sind, so daß der Einlaufteil I diskontinuierlich und der Feuerbeschichtungsteil II im kontinuierlichen Betrieb arbeitet. Der Einlaufteil I umfaßt eine Hauptbeize 1, eine Spüle 2 und einen Trockner 3. Der Feuerbeschichtungsteil II weist in der nachstehenden Reihenfolge einen Streckrichter bzw. eine Streckbiegerichtmaschine 4, eine Nachbeize 5, eine Spüle 6, einen Trockner 7, in horizontaler oder vertikaler Bauweise einen unter Schutzgasatmosphäre eingestellten Ofen 8 und zur Feuerbeschichtung abschließend ein Schmelzbad 9 auf.The only figure shows a system diagram for the hot-dip coating of a Metal band by fire coating. The system consists of an inlet part I and a fire coating part II, these two parts from each other are decoupled, so that the inlet part I discontinuously and the hot-coating part II works in continuous operation. The inlet part I comprises a main stain 1, a sink 2 and a dryer 3. The fire-coating part II has a stretching judge or a stretch-leveling machine 4, a pickling 5, a sink 6, a dryer 7, in a horizontal or vertical construction one under a protective gas atmosphere set furnace 8 and finally a melt pool for fire coating 9 on.

Dem Einlaufteil I ist eine Abwickelstation 10 (Doppel- oder Wendehaspel) mit sich anschließender Schweißmaschine 11 und eine Schlingengrube 12 vorgeschaltet. Zwischen dem Einlaufteil I, und zwar im Anschluß an den dortigen Trockner 3, und dem Feuerbeschichtungsteil II ist ein im Ausführungsbeispiel horizontaler Band- bzw. Einlaufspeicher 13 angeordnet.The inlet part I is an unwinding station 10 (double or reversible reel) subsequent welding machine 11 and a loop pit 12 upstream. Between the inlet part I, namely after the one there Dryer 3, and the fire coating part II is one in the embodiment horizontal tape or inlet storage 13 arranged.

Ein zu behandelndes Metallband 14 gelangt in Form eines Bandcoils 15 in die Abwickelstation 10 der dargestellten Anlage und durchläuft diese in Richtung des ausgangsseitigen Pfeils. In der Schweißmaschine 11 wird das Bandende eines ersten Coils mit dem Bandanfang eines folgenden Coils verschweißt, so daß das Metallband 14 als Endlosband durch die Anlagenteile geführt wird. Unter Zwischenschaltung der eine gewisse Speicherkapazität bietenden Schlingengrube 12 gelangt das Metallband 14 aus der Schweißmaschine 11 direkt in die Hauptbeize 1 und die sich anschließenden Anlagenteile 2 bzw. 3 des Einlaufteils I, so daß in dem die Hauptspeicherkapazität bereitstellenden Einlaufspeicher 13 sowie auch die folgenden Anlagenteile des Feuerbeschichtungsteils II ein stets zunderfreies Band einläuft. Da weder im Einlaufspeicher 13 noch der sich diesem anschließenden Streckbiegerichtmaschine 4 Zunder anfallen kann, ist es nicht mehr erforderlich, diese Anlagenteile einzukapseln und mit zusätzlichen Absaug- und Filtereinrichtungen auszurüsten. Schließlich machen die entkoppelten Anlagenteile I und II einen verfahrensbedingt notwendigen kurzen Stillstand unschädlich, gleich ob dieser im Einlaufteil I bzw. im Feuerbeschichtungsteil II auftritt.A metal strip 14 to be treated arrives in the form of a strip coil 15 Unwinding station 10 of the system shown and runs through it in the direction the arrow on the output side. The end of the strip is in the welding machine 11 of a first coil welded to the beginning of the strip of a subsequent coil, see above that the metal strip 14 is passed through the system parts as an endless strip. With the interposition of those offering a certain storage capacity In the loop pit 12, the metal strip 14 comes out of the welding machine 11 directly into the main pickling 1 and the subsequent system parts 2 or 3 of the inlet part I, so that in the main storage capacity Inlet store 13 and also the following parts of the system of the fire-coating part II a scale that is always free of scale runs in. Because neither in the inlet storage 13 nor the 4 scale straightener following this it may no longer be necessary to encapsulate these parts of the system and to be equipped with additional suction and filter devices. Finally decoupled system parts I and II make a process-related necessity short standstill harmless, regardless of whether this is in the inlet part I or in Fire coating part II occurs.
