Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Kupferprofils und ein Kupferprofil.The invention relates to a method for producing a copper profile and a copper profile.
Die Herstellung von einem Kupferdraht mit einem Metall-Matrix-Composit (MMC) erfolgt durch verschiedene Prozesse. Beim schmelzmetallurgischen Prozess erfolgt eine Infiltration von Fasern oder Partikeln durch Vakuum oder Druck und ein Einführen von Partikeln in die Schmelze mit anschließender Weiterverarbeitung durch Gieß- und Umformverfahren. Auch können pulvermetallurgische Prozesse erfolgen, bei denen Pulvermixturen gesintert werden. Auch das Beschichten aus einer Gasphase (PVD/CVD), elektrolytische Abscheidung oder Plasmaspritzen ist möglich. Im Allgemeinen sind Verfahrensschritte wie Gieß-Walz-Drahtherstellung, Grobdrahtzug und Feindrahtzug notwendig. Durch das Verwenden von Legierungen oder durch Umformen eines Kupferprofils reduziert sich die elektrische Leitfähigkeit erheblich. Zudem wird die Verarbeitung von höher festen Legierungen zu Drähten mit einem Durchmesser kleiner 0,3mm durch die geringe Umformbarkeit immer aufwändiger.The production of a copper wire with a metal matrix composite (MMC) is carried out by various processes. In the metallurgical melt process, fibers or particles are infiltrated by vacuum or pressure and particles are introduced into the melt with subsequent further processing by casting and forming processes. Also powder metallurgical processes can take place in which powder mixtures are sintered. Coating from a gas phase (PVD / CVD), electrolytic deposition or plasma spraying is also possible. In general, process steps such as cast-rolled wire making, rough wire drawing and fine wire drawing are necessary. By using alloys or by forming a copper profile, the electrical conductivity is reduced considerably. In addition, the processing of higher-strength alloys into wires with a diameter of less than 0.3 mm due to the low formability becomes more complex.
Aufgabe ist es den Stand der Technik zu verbessern.The task is to improve the state of the art.
Gelöst wird die Aufgabe durch ein Verfahren zum Herstellen eines Kupferprofils gemäß dem Hauptanspruch. Vorteilhafte Ausgestaltungen ergeben sich aus den diesbezüglichen Unteransprüchen.The object is achieved by a method for producing a copper profile according to the main claim. Advantageous embodiments will be apparent from the relevant subclaims.
Zudem wird die Aufgabe gelöst durch ein Kupferprofil gemäß dem Anspruch 9, wobei sich vorteilhafte Ausgestaltungen aus dem Unteranspruch 10 ergeben.In addition, the object is achieved by a copper profile according to claim 9, wherein advantageous embodiments of the dependent claim 10 result.
Mit dem erfindungsgemäßen Verfahren kann insbesondere ein Draht mit einem MMC hergestellt werden, bei dem der Durchmesser im Wesentlichen frei wählbar ist und insbesondere kleiner 0,3mm Durchmesser sein kann. Somit kann ein quasi endloser Draht (Draht beliebiger Länge) hergestellt werden, welcher beispielsweise Filamente aus Kohlenstofffasern oder Siliziumcarbidfasern beinhaltet. Auch können weitere Filamentmaterialien einsetzbar sein.With the method according to the invention, in particular, a wire can be produced with an MMC in which the diameter is essentially freely selectable and in particular can be smaller than 0.3 mm in diameter. Thus, a quasi-endless wire (wire of arbitrary length) can be produced, which includes, for example, filaments of carbon fibers or silicon carbide fibers. Also, other filament materials can be used.
Vorteilhafter Weise kann der MMC-Draht direkt aus einer Kupferschmelze ohne die herkömmlichen Verfahrensschritte wie beim Gieß-Walz-Draht oder Upcast, Grobdrahtzug und Feindrahtzug erfolgen.Advantageously, the MMC wire can be made directly from a copper melt without the conventional process steps such as cast rolled wire or upcast, rough wire and fine wire draw.
Somit werden mit den vorliegenden erfindungsgemäßen Verfahren Kupferprofile und insbesondere Kupferdrähte hergestellt, die in Bezug auf Zugfestigkeit und Dauerschwingfestigkeit sowie Dichte optimierte Materialeigenschaften haben.Thus, the present inventive method copper profiles and in particular copper wires are produced, which have in terms of tensile strength and fatigue strength and density optimized material properties.
Ganz besonders vorteilhaft ist, dass ein Kupferdraht frei von Umformprozessen hergestellt werden kann, welcher eine optimierte elektrische Leitfähigkeit bereitstellt.It is particularly advantageous that a copper wire can be produced free of forming processes, which provides an optimized electrical conductivity.
Ein Kern der Erfindung beruht insbesondere darauf, dass ein Filament, durch einen Tiegel mit Kupferschmelze geführt ist und, dass eine Öffnung, welche das Filament durch den Tiegel und durch eine Kupferschmelze führt derart ausgestaltet ist, dass Kupferschmelze über diese Öffnung nicht aus dem Tiegel austreten kann.A core of the invention is based in particular on the fact that a filament is guided through a crucible with molten copper and that an opening, which leads the filament through the crucible and through a molten copper, is designed such that molten copper does not escape from the crucible via this opening can.
Weiterer Kern der Erfindung beruht insbesondere darauf, dass durch eine Zuggeschwindigkeit des Filaments/Kupferprofils durch die Kupferschmelze und nachgeordneter Wärmebehandlung der Durchmesser des Kupferdrahtes einstellbar ist.Another core of the invention is based in particular on the fact that the diameter of the copper wire can be adjusted by a pulling speed of the filament / copper profile through the molten copper and subsequent heat treatment.
Auch können Kupferbänder und dergleichen hergestellt werden, wobei in diesem Fall die Öffnung insbesondere ein Langloch ist, durch welches ein Filament oder ein entsprechendes (Filament)Band, welches von der Kupferschmelze umgeben werden soll, geführt und gezogen wird.Also, copper tapes and the like can be produced, in which case the opening is, in particular, a long hole through which a filament or a corresponding (filament) tape to be surrounded by the copper melt is guided and pulled.
