Definitions

  • the invention relates to a method for tempering a groove edge or flank of a crease track section such as grooved rail or grooved rail frog means Welding.
  • DE 550 505 is in a recess of a driving or control head of a grooved rail introduced a wear-resistant bar having at an angle extending portions to barb-like fixed to be.
  • DE 550 506 provides, in heads of grooved rails patches of manganese steel bring in, whereby previously recesses are milled out.
  • DE 195 39 590 A1 relates to a method for reprofiling order-welded Grooved rails, wherein worn sections of driving and leading edge flanks renewed become.
  • WO 97/18921 is a method for welding a filler material on rail sections refer to.
  • DE-C 550 504 discloses Vignol and grooved rails with wear-resistant driving and leading edges from strips, which are introduced into corresponding recesses of the rail heads.
  • the present invention is based on the problem Forming a method of forming a Rillengleisabitess such that very precise and with structurally simple measures cost-effective targeted areas of a groove with wear-resistant Material can be provided.
  • the recess like groove is filled in particular by build-up welding, wherein a plurality of layers formed with optionally different material properties can be.
  • the recess such as groove itself is with a depth t of 10 mm ⁇ t ⁇ 30 mm, in particular t in about 20 mm and / or a Width b with 3 mm ⁇ b ⁇ 15 mm, in particular b in about 10 mm, incorporated into the head of the construction profile.
  • thereupon is in the recess like groove in particular by build-up welding as a material introduced with a filler material, which is suitable both for joint welding to Example of high-alloy stainless steels and mixed connections between these and normal structural steels as well as order materials for rails and switch parts is common.
  • the area of the head with wear-resistant Material are provided in the exposed high wear edges or flanks a groove run.
  • an optimal utilization of introduced weld metal respectively in addition, a quality improvement in the achievable shape and position tolerances and achieved a higher surface quality.
  • a better Economy results d. H.
  • a larger area can be added to protective driving or leading edges are tempered by welding. This is done for this purpose Forming the groove and the surface treatment of the annealed area in one Operation, namely during incorporation such as milling the groove.
  • Fig. 1 is a cross section through a grooved rail 10 with foot 12, web 14 and head 16th illustrated in which a groove 18 is incorporated for guiding a wheel.
  • a groove 18 is incorporated for guiding a wheel.
  • a head 24 of a corresponding construction profile is shown in FIG. 2 shown.
  • the area in which the groove 18 is to be incorporated is punctured. at the design profile may be z. B. to a thick bar rail, a square profile or other profile element act with full head.
  • grooves 28, 30 incorporated by the the edges 20, 21 of the later to be formed groove 18 are cut. Then the Grooves 28, 30 preferably filled in multiple layers by build-up welding (areas 31, 33), wherein the welding material filler materials are added, the desired low-wear Have properties. After filling the grooves 28, 30 then the groove 18, the above-mentioned cut the grooves 28, 30, incorporated.
