Definitions

  • the invention relates to a Switzerlandkraftübertragungs- wire or combinations of wires, such as bundles, strands and ropes, and the use of an austenitic manganese steel for a wire or a combination of wires, in particular bundles, strands and ropes, for the transmission of tensile forces and a Method for producing a steel wire.
  • wires that are used in particular for the production of ropes i. be subjected to tensile stress, made of carbon steel.
  • a high strength of the wires is achieved by work hardening in the manufacturing process (pulling).
  • the wires need a pearlitic structure, whereby their carbon content is set at about 0.8%.
  • the carbon content therefore determines the initial strength of this steel;
  • An increase in strength is therefore achieved primarily by the degree of deformation in the work hardening.
  • the forming process reduces the wire diameter gradually to the final diameter.
  • the ratio between the initial diameter and the final diameter is referred to herein as the degree of deformation.
  • austenitic steel for the production of wires is so far only for the production of spring wires Known which pressure forces are exposed, which lead to multi-dimensional stress states.
  • austenitic steel for producing such a spring wire which has a diameter ⁇ 0.3 mm, for example, in the US 6,123,784 as well as the US 5,651,937 described.
  • a coupling rod in which a rod sheath made of an austenitic Mn high carbon steel. On the coupling rod engage hinge arches of belt connectors for connecting belt ends of conveyor belts.
  • the coupling rod thus claimed transversely to its longitudinal direction.
  • the AT 337 235 B generally discloses a special austenitic stainless steel for producing highly stressed mounts in engine and generator construction and pump housings and submarine cables for information transmission.
  • the aim of the present invention is in contrast a linear tensile force transmission element, in particular wires for ropes and To provide cable components, in which higher strengths of wires with a larger diameter or the same strength of the wires can be achieved with a lower degree of deformation. Also, the specific use of a wire or combination of wires and the method of making a steel wire are the subject of the present invention.
  • austenitic manganese steels have a face centered cubic lattice structure
  • the formation of an austenitic structure is ensured at a manganese content> 10 weight percent, as manganese considerably expanded the so-called ⁇ -range. Due to the higher initial strength of the material and / or a higher degree of deformation thus higher strengths of wires with a larger diameter can be achieved. Due to the stronger cold work hardening of the austenitic steel, the cubic-face-centered atomic lattice structure also allows higher strengths to be achieved with wires of pearlitic structure, even with the same degree of deformation. Furthermore, at least the same strength can be achieved even with a lower degree of deformation, which in particular a better Resumformtar the wire is obtained.
  • Tests have shown that it is expedient for improving the strain hardening properties that the steel in weight percent has a manganese content ⁇ 24, in particular ⁇ 22. In particular, it is favorable for increasing the degree of deformation, if the steel in weight percent has a manganese content between 12 and 18.
  • the process of a tensile transfer wire according to the invention is characterized in that the wire is cold-worked after quenching from a temperature> 1000 ° C and cold working, in particular rolling or drawing. Depending on the intended final diameter, depending on the formability of the wire between the forming steps, it is again annealed to a temperature> 1000 ° C. and then quenched.
  • an austenitic steel containing this alloy composition is particularly well suited for the production of tension transmission wires or rope components such as bundles and strands.
  • tension transmission wires or rope components such as bundles and strands.
  • a higher strength of about 3000 N / mm 2 to 3200 N / mm 2 can be achieved.
  • thicker wires with a diameter of 3 mm with strengths of between about 2200 N / mm 2 to 3000 N / mm 2 can be produced, whose remoulding capacity is considerably better than conventional wires made of carbon steel.
  • Comparatively thin wires, eg with a diameter of less than 1 mm, consisting of an austenitic steel can be drawn with a strength greater than 3200 N / mm 2 .
