Description
Die Erfindung betrifft ein Verfahren zum Auftragen einer wässrigen Behandlungslösung auf die Oberfläche eines sich mit einer vorgegebenen Bandgeschwindigkeit bewegenden Bands, insbesondere eines Stahlbands. Gegenstand der Erfindung ist weiterhin eine Auftragsvorrichtung zum Auftragen einer wässrigen Behandlungslösung auf die Oberfläche eines Bands sowie eine Vorrichtung zur Durchführung des Verfahrens, welche eine solche Auftragsvorrichtung enthält.The invention relates to a method for applying an aqueous treatment solution to the surface of a belt moving at a predetermined belt speed, in particular a steel belt. The invention further relates to an application device for applying an aqueous treatment solution to the surface of a belt and to an apparatus for carrying out the process which contains such an application device.
Aus dem Stand der Technik ist es bekannt, die gegebenenfalls beschichtete Oberfläche eines Stahlblechs mit einer wässrigen Behandlungslösung zu behandeln, um das Stahlblech oxidationsbeständig zu machen und den Reibwert zu erniedrigen, damit das Stahlblech bei einer nachfolgenden Verarbeitung, beispielsweise bei der Herstellung von Verpackungsbehältern, besser verarbeitbar und umformbar ist. Aus den Veröffentlichungen
Alternativ zum Aufsprühen einer wässrigen Behandlungslösung auf die Oberfläche des Bands kommt auch eine Applizierung des Behandlungsmittels durch ein Tauchverfahren in Betracht. Sowohl bei den bekannten Sprühverfahren als auch bei den Tauchverfahren ist es zur Erzielung einer homogenen Verteilung des Behandlungsmittels über die gesamte Oberfläche des Bands erforderlich, die wässrige Lösung im Überschuss auf die Oberfläche des Bands aufzubringen und den überschüssigen Anteil der Behandlungslösung beispielsweise mittels Abquetschrollen wieder zu entfernen. Deshalb weisen sowohl die herkömmlichen Sprühverfahren als auch die Tauchverfahren den Nachteil auf, dass größere Mengen der wässrigen Behandlungslösung benötigt werden und dass ein überschüssiger Anteil der Behandlungslösung, der beispielsweise mittels Quetschrollen von der Oberfläche des Bands abgequetscht wird, in Sammelbehältern gesammelt und einer Wiederaufbereitung zugeführt werden muss. Bei den bekannten Sprüh- und Tauchverfahren kommt es darüber hinaus häufig zu einem ungleichmäßigen Auftrag der wässrigen Behandlungslösung auf die Oberfläche des Bands. Dies macht sich vor allem dann bemerkbar, wenn das Band mit einer hohen Bandgeschwindigkeit von beispielsweise mehr als 400 m/min durch ein Tauchbad mit der Behandlungslösung bewegt wird oder wenn auf ein mit entsprechenden Bandgeschwindigkeiten bewegtes Band im Sprühverfahren eine wässrige Behandlungslösung aufgebracht wird.As an alternative to spraying an aqueous treatment solution onto the surface of the belt, it is also possible to apply the treatment agent by means of a dipping process. Both in the known spraying methods and in the dipping methods, in order to achieve a homogeneous distribution of the treating agent over the entire surface of the belt, it is necessary to apply the aqueous solution in excess to the surface of the belt and to remove the excess portion of the treating solution, for example by means of squeezing rollers , Therefore, both the conventional spraying methods and the immersing methods have the disadvantage that larger amounts of the aqueous treatment solution are required and that an excess portion of the processing solution, which is squeezed from the surface of the belt, for example by means of squeezing rollers, collected in collecting tanks and recycled got to. In addition, the known spraying and dipping processes are frequent uneven application of the aqueous treatment solution to the surface of the belt. This becomes particularly noticeable when the belt is moved at a high belt speed of, for example, more than 400 m / min through a dipping bath with the treatment solution or when an aqueous treatment solution is applied to a belt moving at appropriate belt speeds using the spray method.
Zur Vermeidung dieser Nachteile schlägt die
Hiervon ausgehend besteht die Aufgabe der Erfindung darin, ein Verfahren zum Auftragen einer wässrigen Behandlungslösung auf die Oberfläche eines bewegten Bands aufzuzeigen, mit dem eine möglichst gleichmäßige Applizierung der Behandlungslösung auf die Bandoberfläche ermöglicht wird, ohne dass es nach dem Trocknen der aufgebrachten Behandlungslösung zu fleckigen Erscheinungen an der Bandoberfläche kommen kann. Eine weitere Aufgabe der Erfindung besteht darin, eine Vorrichtung zur Durchführung des Verfahrens aufzuzeigen, mit der möglichst effizient und mit geringem Ausschuss eine wässrige Behandlungslösung auf die Oberfläche eines bewegten Stahlbands in möglichst homogener Verteilung aufgebracht werden kann.On this basis, the object of the invention is to show a method for applying an aqueous treatment solution to the surface of a moving belt, with the most uniform application of the treatment solution is made possible on the strip surface without it after blotting the applied treatment solution to blotchy appearances can come on the tape surface. A further object of the invention is to provide a device for carrying out the method, with which an aqueous treatment solution can be applied to the surface of a moving steel strip in as homogeneous a distribution as possible and with low rejection.
Diese Aufgaben werden mit einem Verfahren mit den Merkmalen des Anspruchs 1, einer Auftragsvorrichtung mit den Merkmalen des Anspruchs 10 sowie mit einer Vorrichtung zur Durchführung des Verfahrens mit den Merkmalen des Anspruchs 13 gelöst. Bevorzugte Ausführungsformen des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Vorrichtungen sind den abhängigen Ansprüchen zu entnehmen.These objects are achieved with a method having the features of
In dem erfindungsgemäßen Verfahren wird eine wässrige Behandlungslösung zunächst mittels eines Rotationssprühers auf wenigstens eine rotierende Walze eines Rollcoaters aufgesprüht, wobei der Rotationssprüher mehrere in Längsrichtung der Walze nebeneinander angeordnete Sprührotoren aufweist, denen die wässrige Behandlungslösung zugeführt wird und welche von einem Sprührotorenantrieb in Rotation versetzt werden, um die Behandlungslösung zentrifugalkraftbedingt in Form eines Sprühstrahls auf die Oberfläche der Walze zu sprühen. Die wässrige Behandlungslösung wird anschließend auf wenigstens eine Oberfläche des sich mit einer vorgegebenen Bandgeschwindigkeit bewegenden Bands durch Vorbeiführen des Bands an einer rotierenden Applikationswalze des Rollcoaters aufgetragen, wobei die wässrige Behandlungslösung in Form eines Nassfilms von der Applikationswalze auf die Oberfläche des Bands übertragen wird.In the method according to the invention, an aqueous treatment solution is first sprayed onto at least one rotating roll of a roll coater by means of a rotary sprayer, the rotary sprayer having a plurality of spray rotors arranged side by side in the longitudinal direction of the roll, to which the aqueous treatment solution is supplied and which are rotated by a spray rotor drive, to spray the treatment solution due to centrifugal force in the form of a spray jet on the surface of the roller. The aqueous processing solution is then applied to at least one surface of the tape moving at a predetermined tape speed by passing the tape past a rotating applicator roll of the roll coater, wherein the aqueous processing solution is transferred in the form of a wet film from the applicator roll to the surface of the tape.
Bei der rotierenden Walze des Rollcoaters, auf welche die Behandlungslösung zunächst durch den Rotationssprüher aufgesprüht wird, kann es sich in einer ersten Ausführungsform der Erfindung um die Applikationswalze selbst handeln. In einer alternativen Ausführungsform der Erfindung kann es sich jedoch bei der rotierenden Walze, auf welche die Behandlungslösung durch den Rotationssprüher aufgesprüht wird, auch um eine Transferwalze handeln, welche in Bezug auf die Applikationswalze des Rollcoaters so angeordnet ist, dass deren Achsen parallel zueinander verlaufen und deren Oberflächen miteinander in Kontakt stehen. In dieser Ausführungsform der Erfindung wird die wässrige Behandlungslösung zunächst von dem Rotationssprüher auf die rotierende Transferwalze aufgesprüht und von dieser auf die daran abrollende Applikationswalze übertragen. Die Applikationswalze appliziert die wässrige Behandlungslösung auf wenigstens eine Oberfläche des Bands, indem das Band mit der Bandgeschwindigkeit an der rotierenden Applikationswalze vorbeigeführt wird. Die Transferwalze und die Applikationswalze rotieren dabei gegensinnig und bevorzugt mit gleicher oder zumindest annähernd gleicher TangentialGeschwindigkeit.In the rotating roll of the roll coater, on which the treatment solution is first sprayed on by the rotary sprayer, in a first embodiment of the invention it may be the application roll itself. However, in an alternative embodiment of the invention, the rotating roll on which the treatment solution is sprayed by the rotary sprayer may also be a transfer roll which is arranged with respect to the application roll of the roll coater so that their axes are parallel to each other and whose surfaces are in contact with each other. In this embodiment of the invention, the aqueous treatment solution is first sprayed by the rotary sprayer on the rotating transfer roller and transferred from this to the application roller rolling thereon. The applicator roll applies the aqueous processing solution to at least one surface of the belt by passing the belt past the rotating applicator roll at belt speed. The transfer roller and the application roller rotate in opposite directions and preferably with the same or at least approximately the same tangential velocity.
In beiden Ausführungsformen der Erfindung steht die Oberfläche der Applikationswalze in einem Übertragungsbereich mit der Oberfläche des Bands in Kontakt, wobei in diesem Übertragungsbereich die Richtung der Tangentialgeschwindigkeit der Oberfläche der rotierenden Applikationswalze der Bandlaufrichtung des sich mit der Bandgeschwindigkeit (linear) bewegenden Bands entspricht.In both embodiments of the invention, the surface of the application roller is in contact with the surface of the belt in a transfer region, in which transfer region the direction of the tangential velocity of the surface of the rotating application roller corresponds to the tape travel direction of the belt moving (linearly) with the belt speed.
Die Bandgeschwindigkeit liegt regelmäßig bei mehr als 200 m/min und entspricht bspw. der Bandgeschwindigkeit mit der Stahlbänder in Bandbeschichtungsanlagen (wie z.B. Bandverzinnungsanlagen) bewegt werden und welche typischerweise zwischen 200 und 700 m/min liegen. Der Betrag der Tangentialgeschwindigkeit der rotierenden Applikationswalze entspricht dabei zumindest im Wesentlichen dem Betrag der Bandgeschwindigkeit. Dies ermöglicht eine effiziente Applizierung der wässrigen Behandlungslösung von der Oberfläche der Applikationswalze auf eine Oberfläche des Bands, ohne dass es zu einer Reibung bzw. einem Schlupf zwischen dem sich bewegenden Band und der rotierenden Applikationswalze kommen kann.The belt speed is regularly greater than 200 m / min and corresponds, for example, to the belt speed with which steel belts are moved in belt coating systems (such as strip-tinning systems) and which are typically between 200 and 700 m / min. The amount of the tangential speed of the rotating application roller corresponds at least substantially to the amount of belt speed. This allows efficient application of the aqueous processing solution from the surface of the applicator roll to a surface of the belt without the possibility of friction or slippage between the moving belt and the rotating applicator roll.
Zweckmäßig wird das Band vor dem Aufbringen der wässrigen Behandlungslösung mit einem Gasstrom getrocknet, bevor das Band in dem Übertragungsbereich mit der Oberfläche der rotierenden Applikationswalze in Kontakt kommt. Die Trocknung des Bands erfolgt dabei bevorzugt mit einem "Air-Knife", welches einen laminaren Heißluftstrom auf die Oberfläche des sich bewegenden Bands aufbläst.Suitably, prior to application of the aqueous treatment solution, the belt is dried with a gas stream before the belt in the transfer region comes into contact with the surface of the rotating application roller. The drying of the tape is preferably carried out with an "air knife", which inflates a laminar flow of hot air on the surface of the moving belt.
Um eine möglichst gleichmäßige Beschichtung der Bandoberfläche mit der Behandlungslösung zu erreichen, kann es zweckmäßig sein, den durch die Applikationswalze auf die Bandoberfläche aufgebrachten Nassfilm der Behandlungslösung mittels angetriebener Glättrollen zu vergleichmäßigen. Hierfür sind rotierend angetriebene Glättrollen in Bandlaufrichtung nach dem Übertragungsbereich angeordnet. Entweder unmittelbar nach dem Applizieren der wässrigen Behandlungslösung auf die Bandoberfläche mittels der Applikationswalze oder nach dem Vergleichmäßigen des mit der Applikationswalze aufgebrachten Nassfilms durch die Glättrollen wird der Nassfilm der Behandlungslösung zur Erzeugung einer Trockenauflage getrocknet. Die Trocknung kann dabei in einem Ofen erfolgen oder durch Bestrahlung der mit der Behandlungslösung beschichteten Bandoberfläche mit Infrarotstrahlung.In order to achieve the most uniform possible coating of the strip surface with the treatment solution, it may be expedient to uniformize the wet film of the treatment solution applied by the application roller to the strip surface by means of driven smoothing rolls. For this purpose, rotating driven smoothing rollers are arranged in the strip running direction after the transfer area. Either immediately after the application of the aqueous treatment solution to the strip surface by means of the application roller or after the wet film applied with the application roller has been uniformed by the smoothing rollers, the wet film of the treatment solution is dried to produce a dry coating. The drying can be carried out in an oven or by irradiation of the coated with the treatment solution strip surface with infrared radiation.
Zur Erzielung eines möglichst effizienten Nassfilmauftrags auf die Bandoberfläche kann die den Sprührotoren pro Zeiteinheit zugeführte Menge der wässrigen Behandlungslösung an die Bandgeschwindigkeit des Bands angepasst werden. Dadurch wird mittels der Sprührotoren auf die rotierenden Walzen des Rollcoaters (gegebenenfalls direkt auf die Applikationswalze) nur die tatsächlich zur Erzielung einer gewünschten Trockenauflage der Behandlungslösung erforderliche Menge der wässrigen Behandlungslösung auf die Applikationswalze und von dieser auf die zu behandelnde Oberfläche des Bands aufgebracht. Weiterhin ist es durch diese Maßnahme möglich, die Bandgeschwindigkeit bei laufendem Verfahren zu ändern, ohne dass dadurch eine zu hohe oder zu geringe Menge der Behandlungslösung auf die Applikationswalze des Rollcoaters aufgebracht wird. Auf diese Weise kann einerseits eine gewünschte Trockenauflage der Behandlungslösung eingehalten und andererseits das Entstehen von überschüssiger Behandlungslösung auf der Bandoberfläche vermieden werden.To achieve the most efficient possible application of wet film to the strip surface, the amount of aqueous treatment solution supplied to the spray rotors per unit time can be adapted to the strip speed of the strip. As a result, by means of the spray rotors on the rotating rolls of the roll coater (optionally directly on the application roll) only the amount of the aqueous treatment solution actually required to achieve a desired dry coverage of the treatment solution is applied to the application roll and from there to the surface of the strip to be treated. Furthermore, it is possible by this measure to change the belt speed while the process is running, without causing too much or too little amount of the treatment solution is applied to the application roller of the roll coater. In this way, on the one hand, a desired dry coverage of the treatment solution can be maintained and, on the other hand, the emergence of excess treatment solution on the strip surface can be avoided.
Zur Versorgung der Rotationssprüher mit der benötigten Menge an wässriger Behandlungslösung sind die Rotationssprüher zweckmäßig mit einer Zufuhreinrichtung gekoppelt, welche eine Zufuhrleitung umfasst, die einerseits mit den Sprührotoren des Rotationssprühers und andererseits mit einem Vorratsbehälter für die Behandlungslösung in Verbindung steht. Die Zufuhreinrichtung ist dabei zweckmäßig über eine Steuereinrichtung automatisiert steuerbar, wobei die Steuereinrichtung auch die Bandgeschwindigkeit des Bands steuert und die den Sprührotoren pro Zeiteinheit zugeführte Menge der Behandlungslösung an die Bandgeschwindigkeit anpasst.To supply the rotary sprayers with the required amount of aqueous treatment solution, the rotary sprayers are expediently coupled to a supply device, which comprises a supply line, which is connected on the one hand to the spray rotors of the rotary sprayer and on the other hand with a reservoir for the treatment solution. The supply device is expediently automatically controllable via a control device, wherein the control device also controls the belt speed of the belt and adapts the spray rotors per unit time supplied amount of the treatment solution to the belt speed.

Das Stahlband 1 wird von einer hier nicht dargestellten Transporteinrichtung mit einer vorgegebenen Bandgeschwindigkeit v in eine Bandlaufrichtung bewegt und dabei über Umlenkrollen U geführt. Zunächst wird das Stahlband 1 durch eine erste Trocknungseinrichtung 4 geleitet, um die Oberflächen des Stahlbands 1 zu trocknen und zu reinigen. Die erste Trocknungseinrichtung 4 ist dabei beispielsweise durch ein "Air-Knife" gebildet, welches einen laminaren Heißluftstrom auf die Oberflächen des sich mit der Bandgeschwindigkeit v durchbewegenden Stahlbands 1 bläst, um dadurch die Stahlbandoberflächen zu trocknen und störende Fremdpartikel abzublasen.The
An die erste Trocknungseinrichtung 4 schließt sich eine Auftragsvorrichtung 10 zum Auftragen einer wässrigen Behandlungslösung auf die Oberfläche des sich mit der vorgegebenen Bandgeschwindigkeit in Bandlaufrichtung v bewegenden Bands 1 an. Die in
Über die Zufuhrleitung 6 und den daran angeordneten Abzweigleitungen wird die wässrige Behandlungslösung den Sprührotoren 3 des Rotationssprühers 2 zugeführt. Die Sprührotoren 3 weisen jeweils einen von einem Antrieb in Rotation versetzten Teller auf. Aufgrund der Rotation des Tellers der Sprührotoren 3 wird die zugeführte wässrige Behandlungslösung durch die Zentrifugalkraft nach außen zum Tellerrand gefördert. Der Tellerrand ist so geformt, dass die wässrige Behandlungslösung in Form feiner Tröpfchen von dem Tellerrand des rotierenden Tellers wegfliegt. Der Tröpfchendurchmesser liegt, abhängig von der Viskosität und der Oberflächenspannung der verwendeten Behandlungslösung, in der Regel zwischen 30 und 70 Mikrometer. Die vom Tellerrand wegfliegenden Tröpfchen der Behandlungslösung werden vollumfänglich um den rotierenden Teller der Sprührotoren 3 versprüht.Via the
Die Sprührotoren 3 des Rotationssprühers 2 sind im Abstand zu dem Rollcoater 20 angeordnet. Der Rollcoater 20 umfasst eine rotierend antreibbare Applikationswalze 21, welche mit einem hier nicht dargestellten Antriebsmotor gekoppelt ist, der sie in Drehung versetzt. Die rotierenden Sprührotoren 3 des Rotationssprühers 2 sprühen die wässrige Behandlungslösung auf die Oberfläche der Applikationswalze 21 des Rollcoaters 20. Die Sprührotoren 3 sind hierfür quer zur Bandlaufrichtung und entlang der Längsachse der Applikationswalze 21 so angeordnet, dass sich die Sprühstrahlen 12 von benachbarten Sprührotoren 3 auf der Oberfläche der Applikationswalze 21 überlappen, um einen gleichmäßigen Auftrag der wässrigen Behandlungslösung über die gesamte Länge der Applikationswalze 21 sicher zu stellen.The
Die rotierende Applikationswalze 21 appliziert die an ihrem Außenumfang anhaftende Behandlungslösung auf eine Oberfläche des sich mit der Bandgeschwindigkeit entlang der Bandlaufrichtung v linear bewegenden Bands 1. Dazu steht das sich bewegende Band 1 in einem Übertragungsbereich 23 mit der Oberfläche der rotierenden Applikationswalze 21 des Rollcoaters 20 in Kontakt. Durch den Kontakt zwischen der der Applikationswalze 21 zugewandten Bandoberfläche und der Oberfläche der Applikationswalze 21 wird die auf der Oberfläche der Applikationswalze 21 anhaftende Behandlungslösung auf die Bandoberfläche übertragen. Die Rotationsrichtung und -geschwindigkeit wird dabei zweckmäßig an die Bandlaufrichtung v und die Bandgeschwindigkeit angepasst, so dass die Richtung der Tangentialgeschwindigkeit an der Oberfläche der rotierenden Applikationswalze 21 im Übertragungsbereich 23 der Bandlaufrichtung v entspricht und der Betrag der Tangentialgeschwindigkeit zumindest im Wesentlichen mit der Bandgeschwindigkeit übereinstimmt.The
Die den Sprührotoren 3 pro Zeiteinheit zugeführte Menge der wässrigen Behandlungslösung wird dabei zweckmäßig an die Bandgeschwindigkeit v angepasst, mit der sich das Stahlband 1 bewegt. Dabei besteht ein linearer Zusammenhang zwischen der den Sprührotoren pro Zeiteinheit zugeführten Menge der Behandlungslösung und der Bandgeschwindigkeit v. Die den Sprührotoren pro Zeiteinheit Δt und bezogen auf die Breite B des Stahlbands 1 zugeführte Menge M der Behandlungslösung variiert dabei in der Regel zwischen M/Δt · B = 0,4 bis 5,5 Liter pro Minute und Meter und liegt bevorzugt zwischen M/Δt · B = 1,0 bis 3,5 Liter pro Minute und Meter. Bei einer typischen Bandgeschwindigkeit von 200 bis 700 m/min beträgt die mit den Sprührotoren 3 auf die Oberfläche des Stahlbands 1 aufgesprühte Menge des Nassfilms der Behandlungslösung zwischen 1 und 8 ml/m2 und bevorzugt zwischen 1 und 3 ml/m2 und besonders bevorzugt ca. 2 ml/m2.The amount of aqueous treatment solution supplied to the
Nach dem Aufbringen der wässrigen Behandlungslösung als Nassfilm auf die oder jede Oberfläche des Stahlbands 1 kann das Stahlband 1 optional zwischen drehend angetriebenen Glättrollen 5a, 5b durchgeführt werden. Die Glättrollen 5 dienen zur Vergleichmäßigung des aufgetragenen Nassfilms der wässrigen Lösung. Bevorzugt wird hierfür ein Glättrollenpaar 5 mit zwei gegeneinander versetzt angeordneten Glättrollen 5a und 5b verwendet. Die versetzte Anordnung der Glättrollen 5a, 5b ist in den
Im Anschluss an die Glättrollen 5 wird das Stahlband 1 durch eine zweite Trocknungseinrichtung 7 geleitet. Bei der zweiten Trocknungseinrichtung 7 kann es sich bspw. um einen Trocknungsofen oder um einen Infrarot- oder Heißluft-Trockner handeln.Following the smoothing
Nach dem Trocknen verbleibt auf der oder jeder Oberfläche des Stahlbands 1 eine gleichmäßige Trockenauflage der Behandlungslösung, wobei die Trockenauflage nach dem Trocknen in der Regel zwischen 1 und 50 mg/m2 und bevorzugt zwischen 2 und 30 mg/m2 liegt. Besonders bevorzugt beträgt die Trockenauflage der Behandlungslösung ca. 10 mg/m2.After drying, a uniform dry coating of the treatment solution remains on the or each surface of the

Auf der anderen Seite des Bands 1, also der der zweiten Bandoberfläche O' zugewandten Seite, ist eine zweite Auftragsvorrichtung 10' angeordnet. Diese dient zum Applizieren der wässrigen Behandlungslösung auf die zweite Bandoberfläche O' des Bands 1 und umfasst ebenfalls einen Rollcoater 20' sowie einen Rotationssprüher 2'. Anders als die erste Auftragsvorrichtung 10 enthält der Rollcoater 20' der zweiten Auftragsvorrichtung 10' zwei rotierende Walzen, nämlich eine erste rotierende Walze 21' in Form einer Applikationswalze und eine zweite rotierende Walze 22 in Form einer Transferwalze. Die Applikationswalze 21' und die Transferwalze 22 werden dabei rotierend angetrieben und die Achsen der beiden rotierenden Walzen 21', 22 verlaufen parallel zueinander. Die Oberflächen der beiden rotierenden Walzen 21', 22 stehen in einer Kontaktzone 24 in Kontakt miteinander. Die beiden rotierenden Walzen 21' und 22 rotieren zweckmäßig mit gleicher Tangentialgeschwindigkeit an ihrer jeweiligen Oberfläche und gegensinnig zueinander.On the other side of the
Im Abstand zur Transferwalze 22 und längs dazu verlaufend ist der Rotationssprüher 2' mit mehreren in Längsrichtung der Transferwalze 22 nebeneinander angeordneten Sprührotoren 3 angeordnet. Mittels des Rotationssprühers 2' wird die wässrige Behandlungslösung zunächst auf die Transferwalze 22 gesprüht und von dieser in der Kontaktzone 24 auf die Applikationswalze 21' übertragen. Die Oberfläche der rotierenden Applikationswalze 21' steht in einem Übertragungsbereich 23 mit der Oberfläche O' des Bands 1 in Kontakt, um die sich auf der Oberfläche der Applikationswalze 21 befindliche wässrige Lösung auf die Oberfläche O' des Bands 1 zu übertragen. Die Rotationsrichtung und -geschwindigkeit ist an die Bandlaufrichtung und die Bandgeschwindigkeit so angepasst, dass die Richtung der Tangentialgeschwindigkeit an der Oberfläche der rotierenden Applikationswalze 21 im Übertragungsbereich 23 der Bandlaufrichtung v entspricht und der Betrag der Tangentialgeschwindigkeit zumindest im Wesentlichen mit der Bandgeschwindigkeit übereinstimmt.At a distance from the

Die Erfindung ist nicht auf die hier zeichnerisch dargestellten und im Detail beschriebenen Ausführungsformen beschränkt. So ist es möglich, für eine einseitige Beschichtung des Bands 1 mit der wässrigen Behandlungslösung lediglich auf einer Seite eine erfindungsgemäße Auftragsvorrichtung 10 bzw. 10' anzuordnen, um die der Auftragsvorrichtung 10 bzw. 10' zugewandte Oberfläche O bzw. O' mit der wässrigen Behandlungslösung zu beschichten. Weiterhin ist es möglich, in dem Rollcoater 20 neben der Applikationswalze 21 und einer gegebenenfalls vorhandenen Transferwalze 22 noch weitere rotierende Walzen vorzusehen, deren Achsen parallel zur Achse der Applikationswalze 21 verlaufen. Wenn mehrere solcher Transferwalzen 22 vorgesehen sind, ist es zweckmäßig, wenn jeder Transferwalze ein Rotationssprüher 2 zugeordnet ist, mit dem die wässrige Behandlungslösung auf die jeweilige Transferwalze gesprüht werden kann. Jede der Transferwalzen steht dabei mit der Oberfläche der Applikationswalze 21 in einer Kontaktzone in Kontakt, um die wässrige Behandlungslösung von der jeweiligen Transferwalze 22 auf die Applikationswalze 21 zu übertragen.The invention is not limited to the drawings illustrated here and described in detail embodiments.

Die Stahlbänder können dabei mit einer metallischen Korrosionsschutzschicht, wie z.B. einer Zinnschicht, beschichtet sein. Bei den wässrigen Behandlungslösungen kann es sich beispielsweise um Passivierungslösungen handeln, wie sie beispielsweise zur Passivierung von Weißblech oder Schwarzblech bekannt sind. Entsprechende Behandlungslösungen sind beispielsweise in der
