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 a distortion-free clamping and / or quenching means, which is cooperatively usable with a positioning means, wherein Control means by which the plant components are tunable to 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 the course of their cooling.
  • discharge means are arranged for the coolant in the basin and / or in the supply lines, which are open for short-term emptying of the basin.
  • discharge means are arranged for the coolant in the basin and / or in the supply lines, which are open for short-term emptying of the basin.
  • the basin on the bottom side at least one coolant inlet per 1.5m basin length, through which a regulated coolant flow can be fed, preferably arranged in the tank above the coolant inlet to this sealed spaced at least one perforated or fürströmbare plate and / or in the flow direction of the coolant downstream of a plate with nozzles or with channels is (are) used.
  • the local cooling intensity of the coolant can be kept the same for the cross-sectional surface areas over the longitudinal rail extension and consequently high uniform quality in the production of hardened rails can be achieved.
  • 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.
