Description
1. Stand der Technik1. State of the art
Bei der Herstellung von Bauteilen mittels Additive Manufacturing (AM) benötigt man Metallpulver mit runden glatten und vollen Metallkugeln mit einer dem nachfolgenden generativen Prozess (beispielsweise Laser Sintering, Elektronenstahl-Schmelzen) angepassten Korngrößenverteilung. Beim Laser Sintering wird beispielsweise eine Korngrößenverteilung von 10 bis 60 μm bevorzugt.In the production of components by means of additive manufacturing (AM), metal powders with round, smooth and full metal spheres are required with a particle size distribution adapted to the following generative process (for example laser sintering, electron beam melting). In the case of laser sintering, for example, a particle size distribution of 10 to 60 μm is preferred.
Bisherige Verfahren zur Herstellung von Metallpulvern nutzen a) das Verdüsen flüssiger Metallschmelze aus einem Tiegel oder aus einer aufgeschmolzenen Stange, oder b) das Verflüssigen eines Metalldrahts in einem durch mehrere Gasplasmastrahlen erzeugten Plasmas. Diese Anlagen arbeiten nach dem Fallstromprinzip in einer vertikalen Anordnung. Das Korngrößenspektrum ist breiter als das benötigte, dieses wird durch nachfolgende Verlust-behaftete Sieb- und Sichtungsprozesse eingestellt.Previous methods for producing metal powders use a) atomizing liquid molten metal from a crucible or from a molten rod, or b) liquefying a metal wire in a plasma generated by a plurality of gas plasma jets. These plants operate on the falling stream principle in a vertical arrangement. The grain size spectrum is wider than what is needed, this is adjusted by subsequent lossy sieving and screening processes.
Die heute üblichen Anlagen und die zugehörigen Prozesse sind seit 1976 beschrieben, unter anderem in
Bisherige Verfahren und Anlagen haben folgende Nachteile:
- a) Komplexe und großvolumige Anlagentechnik
- b) Eine für AM ungünstige Partikelgrößenverteilung, Verluste durch Sieben
- c) Anteil an nichtsphärischen Partikeln hoch, schlechte Fließfähigkeit des Pulvers bei der späteren Verarbeitung
- d) Ausbildung von Hohlkugeln von bis zu 20% der Menge, die bei der nachfolgenden Teile-Produktion zu Fehlstellen führen können
- e) Große Chargen bedingen unflexible Produktion, lange Lieferzeiten
- f) Chargenproduktion kann zu Abweichungen der Zusammensetzung führen
- g) Oxidation der Metallpulver bei Verwendung von Wasser als Dissoziationsfluid oder in der Auffangzone.
- a) Complex and large-volume systems engineering
- b) An unfavorable particle size distribution for AM, losses due to sieving
- c) proportion of non-spherical particles high, poor flowability of the powder in the subsequent processing
- d) formation of hollow spheres of up to 20% of the amount that can lead to defects in the subsequent parts production
- e) Large batches require inflexible production, long delivery times
- f) Batch production can lead to deviations in the composition
- g) oxidation of the metal powders when using water as the dissociation fluid or in the catchment zone.

2. Vorgeschlagene Lösung2. Proposed solution
Die hier vorgeschlagene Anlage vermeidet die oben genannten Nachteile bisheriger Anlagen. Sie unterscheidet sich von bisherigen durch die Art der Plasmaerzeugung mittels Plasmaspritzanlage, die quasi horizontale Führung der Kühlstrecke, einer langen strömungsmechanisch kontrollierten Verdichtungszone für den Sprühstrahl, sowie durch eine Gegenstrom-Bremszone zum Sichten der Metallpulverkörner.The proposed system avoids the above-mentioned disadvantages of previous systems. It differs from hitherto by the type of plasma generation by means of plasma spraying, the quasi-horizontal guidance of the cooling section, a long flow controlled compression zone for the spray jet, and by a countercurrent braking zone for sifting the metal powder grains.
Um die Nachteile bisheriger Anlagen zu kompensieren wird eine Anlagenkonfiguration vorgeschlagen, die charakterisiert ist dadurch, dass sie mit einem Mikroplasma arbeitet, das durch zwei, vier oder durch eine durch 2 teilbare Anzahl von Elektroden erzeugt wird, die mit elektrischen Strom mit einer hohen Stromstärke beaufschlagt werden, so dass zwischen den Elektroden ein Lichtbogen entsteht. Dabei erhitzen sich und schmelzen die metallischen Elektroden. Daher werden die Elektroden aus Rollendraht geformt und mit einem genau definierten Vorschub, der sich nach dem gewünschten Durchsatz und der gewünschten Korngrößenverteilung berechnet, in das Mikroplasma nachgeschoben.In order to compensate for the disadvantages of previous installations, a system configuration is proposed which is characterized in that it operates with a micro-plasma generated by two, four or by a divisible by 2 number of electrodes, which supplies high current with electric current so that an arc is created between the electrodes. During this process, the metallic electrodes heat and melt. Therefore, the electrodes are formed from roller wire and fed into the micro-plasma at a well-defined feed rate, which is calculated according to the desired throughput and the desired particle size distribution.
Anlagen zur Erzeugung des Mikroplasmas sind in ähnlicher Form im Bereich des thermischen Spritzens handelsüblich (siehe z. B.
Ein Trägergasstrom aus Inertgas, vorzugsweise Argon, wird durch das Mikroplasma geführt und trägt die Metallschmelze in die Sprühzone aus.A carrier gas stream of inert gas, preferably argon, is passed through the micro-plasma and carries the molten metal into the spray zone.
Die Metallschmelze wird anschließend in einem zweiten Strom von Inertgas abgekühlt, derart, dass der von den Elektroden abgehende Metallsprühstrahl in der Kühlstrecke durch radial eingeblasenes Inertgas eingeengt wird. Dabei verdichtet sich der kondensierende Metallnebel und bildet im Gasstrom sphärische Kugeln aus. Gleichzeitig verhindert das in der Kühlstrecke radial zugeführte Inertgas, dass die flüssigen Metalltropfen an die Rohrwand anschlagen und diese verschmutzen. Durch die Steuerung der Geschwindigkeiten der Inertgasströme durch Plasmaspritzanlage und Kühlzone kann die Verweildauer der flüssigen Metalltröpfchen in der Spritz- und Kühlzone und damit das Korngrößenspektrum des Pulvers gezielt beeinflusst werden.The molten metal is then cooled in a second stream of inert gas, such that the outgoing from the electrodes metal spray is concentrated in the cooling section by radially injected inert gas. The condensing metal mist condenses and forms spheroidal spheres in the gas stream. At the same time, the inert gas supplied radially in the cooling section prevents the liquid metal drops from striking the pipe wall and causing it to become dirty. By controlling the velocities of the inert gas streams through the plasma spraying system and the cooling zone, the residence time of the liquid metal droplets in the injection and cooling zone and thus the grain size spectrum of the powder can be influenced in a targeted manner.
Die Anlage ist zusätzlich charakterisiert dadurch, dass sich an die Kühlzone eine Bremszone anschließt, in der ein durch eine Düse mit hoher Geschwindigkeit einströmendes Inertgas im Gegenstrom zum Metallpartikelstrahl geführt wird. Die Metallpulverkörner werden im Gegenstrom entsprechend ihres Verhältnisses von Masse zu Oberfläche unterschiedlich abgebremst. Die Anordnung ermöglicht eine optimal steuerbare Sichtung der Metallpulverfraktionen, die an unterschiedlichen Positionen im Rohr in Behältern aufgefangen werden.The plant is additionally characterized by the fact that the cooling zone is adjoined by a braking zone in which an inert gas flowing in through a nozzle at high velocity is introduced into the zone Countercurrent to the metal particle beam is performed. The metal powder grains are braked differently in countercurrent according to their ratio of mass to surface. The arrangement allows optimally controllable screening of the metal powder fractions, which are collected at different positions in the tube in containers.
Die mit der Anlage einsetzbare horizontale Gegenstromverfahren verbessert die Bildung sphärischer Kugeln und vermeidet die Verformung von nicht vollständig erstarrten Kugeln, wie es beispielsweise typisch ist für Anlagen mit einem Wasserbad zum Auffangen der Metallpulverkörner. Gleichzeitig vermeidet diese Anordnung jegliche Benetzung des Pulvers mit Wasser und die anschließende Oxidation der Metalloberflächen des Pulvers.The horizontal countercurrent process which can be used with the system improves the formation of spherical spheres and avoids the deformation of incompletely solidified spheres, as is typical, for example, of plants with a water bath for collecting the metal powder grains. At the same time, this arrangement avoids any wetting of the powder with water and the subsequent oxidation of the metal surfaces of the powder.
Die Anlage ist weiter charakterisiert dadurch, dass das Hauptrohr horizontal aufgestellt wird und in einem Winkel von +45° oder –45° zur horizontalen Achse geneigt werden kann. Dadurch kann die Sichterwirkung, also die Trennung in Kornfraktionen in der Bremszone, beeinflusst werden.The system is further characterized by the fact that the main pipe is placed horizontally and can be tilted at an angle of + 45 ° or -45 ° to the horizontal axis. As a result, the sifter effect, ie the separation into grain fractions in the braking zone, can be influenced.
Die Anlage ist weiter charakterisiert durch eine ringförmige Absaugung, die zwischen der Kühlzone und der Bremszone angeordnet ist. Über einen Filter werden die Feinfraktion, über einen danach angeordneten HEPA-Filter auch kleinste Partikelfraktionen abgeschieden und gesammelt.The system is further characterized by an annular suction, which is arranged between the cooling zone and the braking zone. The fine fraction is separated via a filter and even the smallest particle fractions are separated and collected via a HEPA filter arranged thereafter.
Ergänzt wird die Anlage durch eine Inertgas-Aufbereitungsanlage, die das Inertgas von Wasserdampf und Sauerstoff befreit, um Oxidation des Metallpulvers sicher zu vermeiden.The plant is supplemented by an inert gas treatment plant, which frees the inert gas from water vapor and oxygen to safely avoid oxidation of the metal powder.
Die elektronische Steuerung regelt die Volumenströme des Inertgases über die drehzahlgeregelten Verdichter V1 bis V4, sowie die Vorschubgeschwindigkeit des Elektrodendrahts und die Stromparameter zur Erzeugung des Mikroplasmas.The electronic control regulates the volume flows of the inert gas via the speed-controlled compressor V1 to V4, and the feed rate of the electrode wire and the current parameters for generating the micro-plasma.
