Definitions

  • the invention relates to a method for the thermal treatment of rails, in particular of hot-rolled rail or railway rails with profile parts different mass, the rails from the rolling heat through a targeted thermal treatment and cooling in the profile parts in the profile area, in particular obtained in the rail head, a desired texture with increased strength.
  • the rail head first in the passage in sufficient depth up to 50 mm by means of burner or induction heating to an austenitizing temperature of 950 to 1050 ° C, then with compressed air, the rail head in a first cooling stage within from 10 to 20 seconds to 650 to 600 ° C before the area of pearlite conversion to cool and in a second cooling stage with respect to the first stage throttled Air volume within 2 to 4 minutes to about 400 ° C until the end the Perlitumwandlung to form a fine-lamellar pearlitic structure cool. Subsequently, the rail head is again set to 600 to 650 ° C for heated for a period of 4 to 6 minutes and then quickly to below 100 ° C. deterred.
  • a method Specify through which a targeted thermal treatment specifically during the cooling of the rail head allows and with simple means Microstructure is produced, which has a fine-lamellar perlite, which is characterized by a certain hardness level and associated with a high resistance to abrasion characterized and wherein during the cooling process in particular in the Edge zones of the rail head no bainite arises.
  • the cooling section would have to be operated with a significantly lower heat flux density, or the heat transfer coefficient to be set would be about 30 to 40% lower in order to avoid bainite formation in the edge zones of the rail head.
  • the heat transfer coefficient to be set would be about 30 to 40% lower in order to avoid bainite formation in the edge zones of the rail head.
  • the targeted pre-cooling to a core temperature of the rail head from 750 to 850 ° C can according to the invention by cooling in air with natural convection or forced with the help of fans. But it is also possible with To cool the help of nozzles with a water-air mixture (aerosol cooling), this cooling preferably on a cross tractor with appropriate Number of moorings is made.
  • the surface temperature becomes the rail head center measured without contact using a pyrometer.
  • the boundary zone temperature determined here then depends on the type of cooling and intensity about 30 to 60 ° C below the still existing Kemtemperatur.
  • the temperature of Rail head during the entire thermal treatment starting from entering the Vorkssel issued until leaving the Fertigkühl issued measured.
  • the measured values are transferred to a measuring and control device fed and serve to control the individual process steps to be performed, including heating upstream of the final cooling.
  • FIG. 1 shows the cross section of a rail 1.
  • the rail 1 is made from profile parts of different mass, the rail head 2 with edge zone 5 and Core zone 6, the middle part 3 and the rail foot 4.
  • the edge zone 5 of the rail head Fig. 2 is shown in phantom in Fig. 1; it is the area that is primarily through targeted thermal treatment converted into a fine-lamellar pearlite structure is to be, without that in the thermal treatment in this edge zone or 5 bainite is created in this area.
  • FIG 2 is a schematic system 10 for carrying out the thermal Treatment according to the invention shown.
  • the plant 10 is - in the rolling line x-x behind the last rolling mill 11 arranged one behind the other - from a Pre-cooling device 12, a preferably inductive heating device 13 and a Fertigkühl Surprise 14, of the rail 1 after its exit from the Roll stand 11 are passed through one after the other.
  • the control of the thermal Treatment - includes the intensity of cooling or heating as well the flow rate through the individual system parts 12, 13, 14, happens depending on the respective measured temperature by a measuring and control device 15, which via corresponding lines 16, 17, 18 for the Temperature measured values and the control signals with the respective installation parts 12, 13, 14 are connected.
  • thermo treatment plant can Of course, depending on the type and size of the rails and the type of the selected Pre - and final cooling as well as the scope of the measuring and control device be varied as far as compliance with the arranged one behind the other process steps of the invention is fully preserved content.
