Definitions

  • the present invention relates to a method of fabricating metal wire from metal powder in which the powder by means of flat rollers forms a self-supporting metal wire strip which further takes the form of a laminated structure.
  • the laminated stack of metal wires may be enveloped and the entire assembly reduced to the desired thickness.
  • wire is to be understood to mean herein not only normal wire products of circular sectional area but also wire-shaped products of other profiles, for example of oval or polygonal sectional areas.
  • metal powder is to denote not only powder of a single metal but also is to include powder of metal alloys, mixtures of different metal powders suitable for being converted into an alloy during or after the wire is formed, and powder of metal in conjunction with a restricted quantity, usually not more than about by weight, of powdery, inorganic metal compounds, such as carbides and oxides, which may be desired for obtaining given properties of the final product, for example, an improved wear resistance or creep strength.
  • rollers of suitable diameter for example of about half a metre are capable of providing only a very thin band, for example having a thickness of about 0.5 mm.
  • the manufacture of tape of satisfactory density with a thickness of a few millimetres would require the use of rollers of a diameter of a few metres.
  • rollers for the manufacture of wire from powder in which case many further complications are involved, for example considerable difliculties in the lateral control of the powder supply and the non-uniform pressure distribution owing to the variation in thickness from the centre to the sides of the Wire in its cross section.
  • An advantage of this method is that the conversion of powder into self-supporting tape may be performed with the aid of fiat rollers instead of profiled rollers, which are required for the direct manufactuer of wire from powder.
  • a further advantage is that the final thickness of the tape is not subjected to requirements with respect to the thickness of the tape. It is therefore possible to perform r the initial powder concentration by means of rollers of reasonable diameters, for example a diameter about 10 times smaller than in the case of direct manufacture of wire.
  • Part of the kneading process required for obtaining a satisfactory material density may be performed during the process of working the laminated intermediate product to the wire of the finally desired thickness.
  • a nickel powder (granular size 50 to 200 is rolled between fiat rollers of diameters of 200 mm. with a gap between the rollers of 1.9 mm. to form a tape of a width of 50 mm. and a thickness of 2 mm., which is rolled in five steps to a thickness of 0.2 mm. with intermediate annealing processes in an atmosphere of nitrogen and 25% of hydrogen at 800 C.
  • tapes of copper, iron, nickel-iron and chromium-nickel alloy powder may be manufactured.
  • the tape obtained from the metal powder may be united to a wire-shaped assembly of laminated structure in many ways.
  • a tape 2 of suitable width is wound cylindrically around a narrow metal strip 1 and this process is repeated with a number of further tapes 3, 4, 5 and so on until a wire-shaped assembly of a diameter of for example 5 mm. is obtained.
  • the diameter is subsequently reduced by drawing to about 3 mm., the result being a compact, homogeneous wire.
  • fifteen strips 11 of a width of 3 mm. and a thickness of 0.2 mm. may be stacked and the assembly may be Wrapped up by folding in a tape 12 of a width of 16 mm.
  • the resultant, enveloped stacks are subsequently rolled to a wire of a square profile with a thickness of 2 mm.
  • example powderous substances may be rolled up in layers together with the metal tape.
  • a method of manufacturing metal wire from metal powder comprising rolling said powder with flat rollers.
