Definitions

  • the invention relates to a method for producing a copper profile, in particular a copper wire, from a matrix element, the matrix element having at least one filament. Furthermore, the invention relates to a copper profile.
  • Various methods are known for producing a copper wire from a metal matrix composite (MMC).
  • MMC metal matrix composite
  • fibers or particles are infiltrated by vacuum and / or pressure, particles are stirred into the melt and then further processed by casting and forming processes.
  • Powder metallurgical processes can also be used in which powder mixtures are sintered or sintering or forging of ropes made of metal and non-metal fibers.
  • Coating from a gas phase (PVD / CVD), electrolytic deposition or plasma spraying can also be used.
  • the electrical conductivity is significantly reduced by using alloys and / or by reshaping a copper profile. Furthermore, the processing of higher-strength alloys into wires a diameter of ⁇ 0.3mm is becoming more and more complex due to the low formability.
  • a device for the continuous dew molding of a cast rod in which a core wire of, for example, 7.15 mm made of metal is moved upwards by means of pinch rollers through a hole in the bottom of a crucible in such a way that another molten metal in the crucible attaches to the core wire and a Cast rod is molded.
  • the deposit occurs with a solidification direction perpendicular to the core wire axis and below the melt level in the crucible.
  • a rod is made of a metal / metal composite material but germ MMC.
  • the US 2003/0029902 A1 discloses a method in which fiber-reinforced metal matrix wires for reinforcing a casting are inserted into the casting mold and the latter is subsequently filled with molten metal.
  • the WO 96/27 456 A1 discloses a method of producing a metal strand in which a metal band is passed through passed the bottom of a container filled with melt and after the crystallization of the melt is drawn off over rollers arranged above the container.
  • the opening in the bottom is designed as a slot-shaped channel and the belt speed is selected so that a meniscus with conical radii of curvature forms in the region of the mouth of the channel at the bottom of the container to melt, so that the meniscus extends from a two-phase area Part of liquid metal and solid metallic crystals and is located below the liquid level on the start channel.
  • the US 5 736 199 A describes a method for producing a copper profile.
  • a disadvantage of the abovementioned processes and the generally known processes for producing fine wires with a diameter of ⁇ 0.3 mm are the large number of necessary process steps, in particular cast wire rod production, up-casting, coarse wire drawing, medium wire drawing and fine wire drawing as well as multiple heat treatment.
  • the object of the invention is to improve the prior art.
  • a copper matrix composite wire can thus be produced directly in a single process step by passing the matrix element through the copper melt.
  • the conventional process steps such as for wire rod, up-casting, coarse wire drawing and / or fine wire drawing, are eliminated.
  • the method according to the invention therefore produces copper profiles and in particular copper wires made of MMC, which have optimized material properties with regard to tensile strength, electrical conductivity and fatigue strength as well as density. It is particularly advantageous that a copper wire is produced free from forming processes, which provides an optimized electrical conductivity.
  • An essential idea of the invention is based on the fact that a matrix element is guided through the copper melt by means of an opening in a crucible with copper melt in such a way that the solidification of the copper applied to the matrix element is unaffected by liquid copper in the Crucible takes place and thereby the copper profile is formed directly.
  • a copper matrix wire is thus produced directly in a single process step.
  • a "copper profile” is in particular an elongated component made of copper and the matrix element.
  • a copper profile has, in particular, the same cross section and / or the same surface quality over its entire length.
  • a copper profile is in particular a wire, in particular fine wire, a strip and / or a rod made of a composite copper matrix element.

  • a copper wire can in particular also be a flat, square and / or profile wire.
  • the copper wire has in particular a diameter of 0.1 mm to 30 mm, preferably 0.2 mm to 0.5 mm.
  • the copper wire has in particular a matrix element and thus forms from a copper-non-metal composite material.
  • a “matrix element” is in particular an elongated element which is free of copper and / or copper alloys or metal.
  • the matrix element has in particular at least one filament.
  • a filament means in particular a single fiber of any length.
  • a filament has in particular an inorganic or organic substance.
  • a filament can be, for example, a textile, glass, carbon and / or ceramic fiber.
  • the filament and / or matrix element preferably has a surface property which attracts melt.
  • a “copper crucible” is also called a crucible, in particular a container that is open on one side and in particular. Solid copper in particular can be melted in a melting furnace in a copper crucible.
  • the copper crucible has, in particular, liquid copper, through which the matrix element is guided through an opening.
  • An "opening" is in particular a non-closed point in the bottom of the copper crucible and thus a passage through the bottom of the copper crucible.
  • the opening has in particular any cross section.
  • the opening is preferably adapted to the matrix element being carried out in such a way that liquid copper cannot pass out of the copper crucible through the opening and / or run out.
  • the opening is designed, for example, as a round hole and in the case of a tape as an elongated hole.
  • Liquid copper is understood to mean in particular copper and / or copper alloy in the liquid state, so that the liquid copper is flowable.
  • Solidification of the applied copper on the matrix element free of the liquid copper in the filled copper crucible means in particular that copper already applied to the matrix element is not or only slightly influenced by the liquid copper in the filled copper crucible when it solidifies. In this way, a defined cooling and solidification of the melt takes place at the upper end of the meniscus. This effect leads in particular to the formation of the solidification front over the melt surface and parallel to it. The direction of solidification takes place in particular against the direction of movement of the filament.

  • tensile stress is applied to the matrix element and / or the filament during drawing.
  • the matrix element and / or filament in particular is pulled through the opening and the molten copper of the filled copper crucible.
  • pulling is to be understood in particular in the sense of leading.
  • a direction of solidification of the applied copper on the matrix element is aligned along or parallel to a longitudinal axis of the matrix element.
  • the applied copper thus solidifies along the longitudinal axis of the matrix element, so that a solidification profile can be formed along the matrix element.
  • the direction of solidification is therefore opposite to the direction of pull, as a result of which the extent of the solidification front and the thickness of the solidified copper on the matrix element can be influenced by the speed at which it is carried out and / or pulled.
  • the matrix element with the applied copper is brought out of the copper melt above the liquid level of the liquid copper by carrying out and / or pulling, and the solidification takes place outside the liquid copper above the liquid level.
  • a "solidification direction” is in particular the direction in which the applied copper solidifies onto the matrix element. If, for example, the matrix element is pulled upwards out of the copper crucible with the filled liquid copper into the surrounding atmosphere, the direction of solidification is in particular opposite to the direction of pull, i.e. towards the melt, and aligned vertically. In particular, a stationary solidification front is established.
  • a “longitudinal axis” is in particular the length of the longest dimension of the matrix element.
  • a longitudinal axis is thus in particular the axis running in the longitudinal direction of the matrix element.
  • the longitudinal axis of the matrix element is aligned vertically, so that a free meniscus made of applied copper forms around the matrix element on and / or above a liquid level of the liquid copper in the filled copper crucible.
  • a free meniscus made of applied copper is thus formed around the matrix element, the free meniscus having a self-stabilizing round cross section. This reduces or avoids any post-processing steps.
  • the trained meniscus means that small particles, such as scale and / or crucible material, can collect on the lower base of the meniscus and sink into the liquid copper in the filled copper crucible, so that the area of the solidification front remains free of particles.
  • a wire surface is basically formed that is smooth and free of particles.
  • the solidification of the applied copper on the matrix element can be influenced not only via the drawing speed of the matrix element, but also by deliberately influencing the meniscus.
  • the design of the copper crucible filled with liquid copper such as the liquid level of the liquid copper, the design of the opening in the bottom of the crucible, the temperature and viscosity of the liquid copper, the formation and shape of the meniscus, since this is arranged above the liquid level of the liquid copper in the crucible and thus largely in the surrounding atmosphere, by further parameters , such as the ambient temperature, air pressure and the like, as well as influenced by the temperature of the matrix element on the solidification front.
  • the crucible design and shape as well as the type of filament have a stabilizing effect on the meniscus.

  • a “meniscus” is understood in particular to mean a curvature on the surface of a liquid.

  • the meniscus in particular has a convex shape at the top of the solidification front and a concave shape at the bottom to the liquid level. In particular is on the solidification front, the curvature of the meniscus maximally and decreases as the liquid level approaches.
  • a "free meniscus” means in particular that the meniscus itself is not within the liquid copper in the filled copper crucible, but largely in the surrounding atmosphere. The free meniscus is in particular only in contact with the liquid copper liquid level in the filled copper crucible at its lower base.
  • the “liquid level” is in particular the liquid level of the liquid copper in the filled copper crucible.
  • the liquid level also called the liquid surface, represents in particular the interface between the liquid copper and the surrounding atmosphere arranged above it.
  • the opening is covered by the liquid copper.
  • the matrix element is immediately and immediately surrounded by liquid copper when it is introduced into the opening of the copper crucible. Furthermore, the copper melt cannot escape through the opening from the copper crucible due to utilization of the surface tension of the copper melt.
  • the matrix element has further filaments and / or a bundle of filaments.
  • the proportion of filaments and / or fibers in the MMC profile and / or wire can thus be increased. Furthermore, multifilaments and tied, twisted, braided and / or otherwise connected filaments in particular can be used in a filament bundle. As a result, the tensile strength and fatigue strength can be increased and the density and weight of the manufactured copper profile and / or wire can be reduced.
