Definitions

  • the invention relates to a device for hardening rails, in particular profiled rails, optionally with respectively different cross-sectional shape and a length of greater than 50m by cooling at least part of the respective rail cross-section over the entire rail length in a coolant, consisting of Querverschiebeschn in the area a roller table, of directing means and manipulation gripper for moving the rail in the device, at least one positioning means, each with a basin or trough with coolant and a cooling bed.
  • a coolant consisting of Querverschiebeschn in the area a roller table
  • Rails of carbon-containing, optionally low-alloy steels which are placed on a cooling bed after rolling and allowed to cool, have a pearlitic structure throughout, the material having corresponding mechanical properties.
  • the microstructure can be adjusted in such a way that at least the claimed rail head high hardness, high abrasion resistance and a has low Rissinitiation, ie, that the rail in the track has improved performance characteristics.
  • a device for hardening rails by a targeted formation of the microstructure during the cooling of the same can be designed for a passage through a spray cooling device or for a dip in a coolant.
  • the invention seeks to remedy the deficiencies and sets itself the goal of creating a device of the type mentioned for the hardening of rails, especially profiled rails, with which high throughput with high reliability high quality rails can be produced economically.
  • a plant according to the objective of manipulation gripper for unhindered rapid movement of the expiring from the rollers rails which allows axial alignment of the same, and a dimensionally correct applicability in a positioning and / or depositing on a transfer means and / or on a cooling bed accomplishes positioning means for distortion-free clamping and / or quenching, which is cooperatively employable with a positioning means, wherein control means by which the plant components on each other for a cyclic dipping of the head and / or other parts of the cross section and / or the entire surface of the rail in course are tunable by their cooling.
  • the goal is in a generic device achieved in that the positioning horizontally aligned comprises a plurality of support components with facilities for the foot of a suspended rail, which rail is fixed to the plants by releasable clamping elements or hold-down in the axial direction of the rail horizontally fixed.
  • the advantages achieved with the positioning means according to the invention are essentially to be seen in the fact that they are formed from holding components which are aligned horizontally with great accuracy, each having two installations and two hold-downs.
  • Such a rail from the rolling heat with austenitic structure which is inserted axially aligned by a manipulation gripper in a certain desired position in the holding components, each with two systems for the foot of the rail, are determined by two clamping elements each shift and warping, which determination even with an action of large forces, eg in a cooling phase of the rail head, with high accuracy is maintained.
  • the holding components and the hold-down or clamping elements for the rail foot are provided in the longitudinal extent of the positioning respectively selbarts so that advantageously no bending moments arise in the determination of the rail.
  • the rail is held immovably on both sides by a system f2 and a releasable clamping element for the rail of a component of the positioning and the other systems and elements of the respective components allow a shift in the rail longitudinal direction. Thereby can be stabilized during the cooling or heat treatment, the rail in a desired cross-sectional position, wherein the given by the material contraction shortening is carried out by a shift free of surface damage.
  • FIG. 1 is shown in cross section a device for hardening rails.
  • a rail 1 is spent after the stitch in the last rolling caliber (not shown) on a roller table 2 and positioned by a transverse pushing means 21 on this.
  • An in Fig. 1 illustrated manipulation gripper 3 is designed such that this a track 1 in a lying position on the roller table 2 of this by means of a plurality of pliers 30 on the rail length correctly picks up and aligned by holding the gripping arms 31,31 'axially.
  • the pliers 30 are vertically, horizontally and rotationally movable, so that a laterally located track from the roller table 2, axially directed, turned into a suspended position with a horizontal foot surface, in a Positioning means 4, as in Fig. 3 shown on facilities 41,41 'can be introduced.
  • a rail 1,1 'from the roller table 2 or by a positioning means 4 can be received and stored on a cooling bed 6 or on a transfer means 61.
  • a positioning means 4 is in Fig. 3 shown and has over the length of a rail 1 holding components 40, 40 'with systems 41,41', in which the rail 1 is inserted axially directed. Clamping elements 42, 42 'can be adjusted in the direction of the systems 41, 41' towards the flange ends of a rail foot 11. Positioning means 4 and 5 basin with coolant 50 cooperate during the hardening process of rails 1.
  • FIG. 1 shows in the device at least two basins 5 with coolant 50 axparallel arranged side by side, each of which is usable for curing a rail 1 part of the coolant 50 in the basin 5 has a depth which is greater than the maximum rail height to a full immersion allow the same in the cooling liquid 50.
  • coolant inlet 54 anddeschellenk Rheinen 53 are arranged on the bottom side in the basin 5, wherein to smooth out the flow velocity of the coolant 50 during flow of a rail 1 over the entire length of the basin 5 through-flow plates 51 and / or nozzle plates 52 are used for diving down.
  • Positioning means 4 for rails 1 and pelvis 5 with coolant 50 act together as previously mentioned and are movable relative to one another by means of control devices (not shown) and at least in the positions "dipping of cross-section parts". and / or "head hardening” and / or “full immersion hardening” positionable for periods.
  • a groove rail 1R in comparison with a Vignolschiene 1V in Fig. 4 Axis deviations Az, Ar between head x and axis of the foot can be given y.
  • a the axis shifts Az, Ax corresponding horizontal, axially parallel positioning of positioning means 4 and 5 pelvis can be set.
