Definitions
- the invention relates to a roller for use in a machine for producing and / or finishing a fibrous web such as a paper, board or tissue web according to the preamble of claim 1.
- a roll is made for example DE 36 21 154 A1 known.
- Such rollers are available in a variety of positions and with a variety of functions in the above-mentioned machines.
- rolls with soft cover layers are suitable for pressing and dewatering the fibrous web.
- Rollers with hard surfaces, in particular also with a heating device are mainly used for smoothing and drying.
- thermal coating provides that powder or wires are melted by the introduction of thermal energy and accelerated kinetically on the roll core to be coated.
- the properties and possibilities of the injection processes are essentially given by the ratio of kinetic to thermal energy.
- a roller with a coating of a metal oxide is for example from EP 0870867 B1 known.
- the ceramic layer has 50 to 95% and preferably 55 to 80% of Cr 2 O 3 and 3 to 50% and preferably 20 to 45% of TiO 2 and possibly other metal oxides.
- the sole input of energy into the material to be applied and a cooling rate of up to 10 6 K / s merely lead to a mechanical connection or clamping of the raw material to the roll core.
- a careful preparatory surface treatment such as sandblasting and the like is needed, which is complicated and time-consuming.
- the coating structure is closed in a porous state up to open porosity.
- the porosity can lead to increased corrosion tendency and adhesion problems. Accordingly, the surface of the sprayed layer must be filled, for example by final sealing with a polymer.
- thermal spraying is not an economical or ecological process because of the poor powder application efficiency in terms of ⁇ m per stroke and the percentage of powder remaining on the roll.
- the alloy region has a thickness of 0.5 to 3%, preferably 1%, of the layer thickness of the coating.
- the coating may preferably be made using an inductive device, a plasma gun or a laser.
- the material may be in powder, rod or wire form.
- the coating may comprise at least one layer produced by a single stroke, or preferably several layers generated by several strokes.
- a thermal spray coating according to the prior art ( Fig. 1A ) a coating produced according to the invention by laser cladding ( Fig. 1B ).
- roller coating can range from “only wear-resistant” to “only corrosion-resistant”. Common to all positions, however, is the requirement for good adhesion of the roll coating on the roll core.
- the above-mentioned disadvantages can be alleviated by improved adhesion of the coating to the roll core to the effect that the connection of the coating material is not based on a purely mechanical clamping, but on a metallurgical bond.
- the improved adhesion with a reduced porosity of the coating can also increase the corrosion resistance compared to a conventional thermal spray coating.
- Fig. 1A a section of a roller 1 with a conventional thermal spray coating 2 strong shown schematized cut.
- the spray layer 2 is applied to a roller body 3, which consists of metal, preferably of steel.
- the sprayed layer 2 of metallic, ceramic or cermet materials may at least partially exist.
- the connection of the materials to the roll shell 3 is effected only by a mechanical or positive clamping of the molten particles on the material of the correspondingly prepared roll shell 3.
- the interface 4 thus formed has seen in the radial direction no significant expansion. The attachment is thus limited.
- corrosion by infiltration of water and punctual mechanical overloads such as the passage of a foreign body through a nip between two rollers 1 is thus to be expected that the sprayed layer 2 partially dissolves the roll shell 3. This can lead to endangerment of the operating personnel and damage to subsequent machine parts.
- Fig. 1B in the same view as Fig. 1A a cross section through a coating 5 produced according to the invention by means of laser cladding.
- the connection of the materials which are built up to the coating 5, to the surface of the roll shell 3, is present here to an increased extent, since the energy input is higher overall and not only the materials melted, but also thermal energy in the surface of the roll shell 3 is entered.
- Characterized the roll shell 3 is melted to a small extent, so that the material which is applied by a suitable applicator, can alloy into the material of the roll shell and thus enters into a metallurgical connection with the material of the roll shell 3.
- the kinetic energy thus hardly contributes to the coating process, in contrast to thermal spraying.
- an alloy region 6 constitutes 0.5 to 3%, preferably 1% of the layer thickness of the coating 5 to be built up.
- the alloy region 6 is smaller, so that a finer processing of the materials is possible, which improves the surface quality of the coating 5 and reduces subsequent work steps.
- the coating 5 produced by the laser cladding is usually produced in several strokes, wherein an alloy region also arises between the layers of the individual strokes, since each time the underlying region is remelted and alloyed with the further layer lying thereon. This in turn results in increased adhesion and corrosion resistance.
- Fig. 2 is shown in a highly schematic view of the structure of a coating 5 on a roller 1.
- the roller 1 is rotatably mounted and is suitably driven so that it rotates away under a preferably axially displaceable along the roller 1 application device 7. Thereby, the entire surface of the roll 1 can be coated in a continuous spiral line in at least one or more strokes. However, it is also possible to apply the coating 5 in a different manner, for. B. in radial rings or axial stripes.
- the application device 7 essentially comprises a material supply 8 and an energy source 9, in which the usually powdery material is introduced.
- energy source 9 inductive and plasma generating devices and lasers of various types such as CO 2 laser, HDPL (High Power Diode Laser) or DDL (Direct Diode Laser) are conceivable.
- the construction of a coating 5 by means of laser cladding represents the most technologically feasible variant.
- a major economic advantage of the process is the high separation efficiency compared to thermal coatings with increased layer thickness per stroke ( ⁇ m / pass).

Description
Die Erfindung geht aus von einer Walze zur Verwendung in einer Maschine zur Herstellung und/oder Veredelung einer Faserstoffbahn wie einer Papier-, Karton- oder Tissuebahn nach dem Oberbegriff von Anspruch 1. Eine derartige Walze ist beispielsweise aus
Die letztgenannten Walzen sind dabei früher vielfach aus Granit hergestellt und mit hoher Güte geschliffen worden. Neuere Konzepte sahen Stahlwalzen vor, welche ebenfalls poliert wurden. Da diese Walzen allesamt verschiedene Nachteile wie beispielsweise das hohe Gewicht im Fall der Granitwalzen oder die Anfälligkeit für Korrosion im Fall der Stahlwalzen aufweisen, setzten sich mit der Zeit neue Verfahren zum Beschichten von Walzenkörpern aus Stahl oder aus Verbundwerkstoffen durch, welche eine metallische, keramische oder Cermet-Spritzschicht mittels Verfahren wie HVOF- oder Flammspritzen auf dem Walzenkörper ausbilden. Derartige Walzen sind seit längerer Zeit bekannt und bilden den derzeitigen Stand der Technik beispielsweise bei Zentralpresswalzen, Trockenzylindern und Leitwalzen.The latter rolls are often made in the past many times from granite and ground with high quality. Newer concepts provided for steel rolls, which were also polished. Since all of these rollers have various disadvantages, such as the high weight in the case of granite rolls or the susceptibility to corrosion in the case of steel rolls, new processes for coating roll bodies of steel or composite materials comprising a metallic, ceramic or composite material have been established over time Form cermet sprayed coating on the roll body by means such as HVOF or flame spraying. Such rolls have been known for some time and form the current state of the art, for example in central press rolls, drying cylinders and guide rolls.
Der Prozess des thermischen Beschichtens sieht dabei vor, dass Pulver oder Drähte mittels Eintrags von thermischer Energie erschmolzen und auf den zu beschichtenden Walzenkern kinetisch beschleunigt. Die Eigenschaften und Möglichkeiten der Spritzprozesse sind im Wesentlichen von dem Verhältnis der kinetischen zur thermischen Energie gegeben.The process of thermal coating provides that powder or wires are melted by the introduction of thermal energy and accelerated kinetically on the roll core to be coated. The properties and possibilities of the injection processes are essentially given by the ratio of kinetic to thermal energy.
Eine Walze mit einer Beschichtung aus einem Metalloxid ist beispielsweise aus der
Die bekannten Verfahren sowie die dadurch erzeugbaren metallischen, keramischen oder Cermet-Beschichtungen sind dabei mit diversen Nachteilen behaftet.The known processes and the metallic, ceramic or cermet coatings which can be produced thereby are associated with various disadvantages.
Einerseits kommt es durch den alleinigen Energieeintrag in das aufzubringende Material und eine Abkühlgeschwindigkeit bis zu 106 K/s lediglich zu einer mechanischen Verbindung bzw. Verklammerung des Rohstoffs auf dem Walzenkern. Um diese Verklammerung so effektiv wie möglich zu gestalten, ist eine sorgfältige vorbereitende Oberflächenbehandlung wie Sandstrahlen und dergleichen vonnöten, welche aufwendig und zeitintensiv ist.On the one hand, the sole input of energy into the material to be applied and a cooling rate of up to 10 6 K / s merely lead to a mechanical connection or clamping of the raw material to the roll core. To make this clamping as effective as possible, a careful preparatory surface treatment such as sandblasting and the like is needed, which is complicated and time-consuming.
Andererseits ist die Beschichtungsstruktur je nach Material und/oder Herstellungsprozess geschlossen porös bis hin zu offener Porosität. Die Porosität kann zu erhöhter Korrosionsneigung und zu Haftungsproblemen führen. Entsprechend muss die Oberfläche der Spritzschicht beispielsweise durch abschließende Versiegelung mit einem Polymer verfüllt werden.On the other hand, depending on the material and / or manufacturing process, the coating structure is closed in a porous state up to open porosity. The porosity can lead to increased corrosion tendency and adhesion problems. Accordingly, the surface of the sprayed layer must be filled, for example by final sealing with a polymer.
Des Weiteren ist thermisches Spritzen aufgrund der schlechten Auftragseffizienz des Pulvers hinsichtlich der µm pro Hub und dem Prozentanteil des auf der Walze verbleibenden Pulvers kein ökonomisches und auch kein ökologisches Verfahren.Furthermore, thermal spraying is not an economical or ecological process because of the poor powder application efficiency in terms of μm per stroke and the percentage of powder remaining on the roll.
Es ist dementsprechend Aufgabe der Erfindung, eine Walze anzugeben, deren Beschichtung hinsichtlich ihrer Haftung am Walzenkern und ihrer Korrosionsbeständigkeit den Anforderungen genügt, die durch Papier-, Karton- oder Tissuemaschinen hinsichtlich Temperaturen, Feuchtigkeit und Belastung durch Chemikalien gestellt werden.It is accordingly an object of the invention to provide a roller whose coating satisfies the requirements of its adhesion to the roll core and its corrosion resistance, which are made by paper, board or tissue machines in terms of temperature, humidity and exposure to chemicals.
Die Aufgabe wird gelöst durch die kennzeichnenden Merkmale von Anspruch 1 in Kombination mit den gattungsbildenden Merkmalen.The object is achieved by the characterizing features of claim 1 in combination with the generic features.
Gemäß der Erfindung ist vorgesehen, dass der Legierungsbereich eine Stärke von 0,5 bis 3%, vorzugsweise von 1%, der Schichtstärke der Beschichtung aufweist.According to the invention it is provided that the alloy region has a thickness of 0.5 to 3%, preferably 1%, of the layer thickness of the coating.
Weitere vorteilhafte Ausgestaltungsvarianten und Aspekte der Erfindung gehen aus den Unteransprüchen hervor.Further advantageous embodiments and aspects of the invention will become apparent from the dependent claims.
Die Beschichtung kann bevorzugt unter Verwendung einer induktiven Vorrichtung, einer Plasmakanone oder eines Lasers hergestellt sein.The coating may preferably be made using an inductive device, a plasma gun or a laser.
Vorteilhafterweise kann der Werkstoff in Pulverform, in Stabform oder als Draht vorliegen.Advantageously, the material may be in powder, rod or wire form.
Gemäß vorteilhafter Aspekte der Erfindung kann die Beschichtung zumindest eine Schicht, die durch einen einzelnen Hub erzeugt ist, oder bevorzugt mehrere Schichten, die durch mehrere Hübe erzeugt sind, aufweisen.According to advantageous aspects of the invention, the coating may comprise at least one layer produced by a single stroke, or preferably several layers generated by several strokes.
Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnungen ohne Einschränkung der Allgemeinheit näher beschrieben. In den Figuren zeigen:

In
Die grundsätzliche Aufgabe einer Walzenbeschichtung kann je nach Position in der Papier-, Karton- oder Tissuemaschine von "nur verschleißbeständig" bis hin zu "nur korrosionsbeständig" reichen. Allen Positionen gemein jedoch ist die Forderung nach guter Haftung der Walzenbeschichtung am Walzenkern. Die weiter oben angeführten Nachteile können durch eine verbesserte Haftung der Beschichtung am Walzenkern dahingehend gemildert werden, dass die Anbindung des Beschichtungsmaterials nicht auf einer rein mechanischen Verklammerung, sondern auf einer metallurgischen Bindung beruht.Depending on the position in the paper, board or tissue machine, the basic task of roller coating can range from "only wear-resistant" to "only corrosion-resistant". Common to all positions, however, is the requirement for good adhesion of the roll coating on the roll core. The above-mentioned disadvantages can be alleviated by improved adhesion of the coating to the roll core to the effect that the connection of the coating material is not based on a purely mechanical clamping, but on a metallurgical bond.
Durch diese "echte" Haftung, die nur in einem Bereich von 0,5 bis 3% der Schichtdicke vorhanden sein muss, kann eine Steigerung der Haftzugfestigkeit um bis zu 80% gegenüber einer thermischen Spritzschicht erzielt werden. Dieser Anstieg in der Haftung bringt vor allem je nach Position im Bereich der Sicherheit bei Bespannungsrissen und anderen auch lokalen Überlastungen eine erhöhte Laufzeit.This "true" adhesion, which must be present only in a range of 0.5 to 3% of the layer thickness, an increase in the adhesive tensile strength can be achieved by up to 80% compared to a thermal sprayed layer. This increase in liability, in particular, leads to an increased duration depending on the position in the area of safety in the case of tearing cracks and other local overloads.
In Kombination der verbesserten Haftung mit einer verringerten Porosität der Beschichtung kann zudem die Korrosionsbeständigkeit gegenüber einer herkömmlichen thermischen Spritzschicht erhöht werden.In combination, the improved adhesion with a reduced porosity of the coating can also increase the corrosion resistance compared to a conventional thermal spray coating.
Betrachtet man
Wie weiter oben erläutert, kann die Spritzschicht 2 aus metallischen, keramischen oder Cermet-Werkstoffen zumindest teilweise bestehen. Die Anbindung der Werkstoffe an den Walzenmantel 3 erfolgt lediglich durch eine mechanische bzw. formschlüssige Verklammerung der erschmolzenen Partikel am Material des entsprechend präparierten Walzenmantels 3. Das so gebildete Interface 4 hat in radialer Richtung gesehen keine signifikante Ausdehnung. Die Anhaftung ist somit begrenzt. Insbesondere bei Korrosion durch Unterwanderung von Wasser und bei punktuellen mechanischen Überbelastungen wie beispielsweise beim Durchgang eines Fremdkörpers durch einen Walzenspalt zwischen zwei Walzen 1 ist somit damit zu rechnen, dass sich die Spritzschicht 2 bereichsweise vom Walzenmantel 3 löst. Dies kann zu Gefährdung des Bedienpersonals und zu Schädigungen nachfolgender Maschinenteile führen.As explained above, the sprayed layer 2 of metallic, ceramic or cermet materials may at least partially exist. The connection of the materials to the

Dabei ist es ausreichend, wenn ein Legierungsbereich 6 0,5 bis 3%, bevorzugt 1% der aufzubauenden Schichtstärke der Beschichtung 5 ausmacht.It is sufficient if an alloy region 6 constitutes 0.5 to 3%, preferably 1% of the layer thickness of the
Dies ist in Hinblick auf das ebenfalls bekannte Verfahren des Auftragsschweißens als positiv zu bewerten. Einerseits ist der Legierungsbereich 6 kleiner, so dass eine feinere Verarbeitung der Werkstoffe möglich ist, was die Oberflächenqualität der Beschichtung 5 verbessert und nachfolgende Arbeitsschritte reduziert.This is to be regarded as positive in view of the likewise known process of build-up welding. On the one hand, the alloy region 6 is smaller, so that a finer processing of the materials is possible, which improves the surface quality of the
Andererseits wird die durch das Laser Cladding hergestellte Beschichtung 5 gewöhnlich in mehreren Hüben hergestellt, wobei zwischen den Lagen der einzelnen Hübe ebenfalls wieder ein Legierungsbereich entsteht, da jedes Mal der darunterliegende Bereich erneut angeschmolzen und mit der darauf liegenden weiteren Lage legiert wird. Daraus ergibt sich wiederum erhöhte Haftung und Korrosionsbeständigkeit.On the other hand, the
In
Die Walze 1 ist dabei rotierend gelagert und wird geeignet angetrieben, so dass sie sich unter einer vorzugsweise axial entlang der Walze 1 verschieblichen Auftragsvorrichtung 7 hinwegdreht. Dadurch kann die gesamte Oberfläche der Walze 1 in einer kontinuierlichen Spirallinie in zumindest einem oder mehreren Hüben beschichtet werden. Es ist jedoch auch möglich, die Beschichtung 5 in anderer Weise aufzubringen, z. B. in radialen Ringen oder axialen Streifen. Die Auftragsvorrichtung 7 umfasst im Wesentlichen eine Werkstoffzufuhr 8 und eine Energiequelle 9, in welche der gewöhnlich pulverförmige Werkstoff eingetragen wird.The roller 1 is rotatably mounted and is suitably driven so that it rotates away under a preferably axially displaceable along the roller 1
Als Energiequelle 9 sind induktive sowie plasmaerzeugende Vorrichtungen und Laser verschiedener Typen wie CO2-Laser, HDPL (High Power Diode Laser) oder DDL (Direct Diode Laser) denkbar. Der Aufbau einer Beschichtung 5 mittels Laser Cladding stellt dabei die technologisch am einfachsten zu realisierende Variante dar.As energy source 9 inductive and plasma generating devices and lasers of various types such as CO 2 laser, HDPL (High Power Diode Laser) or DDL (Direct Diode Laser) are conceivable. The construction of a
Ein großer ökonomischer Vorteil des Verfahrens ist in der hohen Abscheideeffizienz gegenüber thermischen Beschichtungen bei erhöhter Schichtstärke pro Hub (µm/pass) zu sehen.A major economic advantage of the process is the high separation efficiency compared to thermal coatings with increased layer thickness per stroke (μm / pass).
