Definitions

  • the invention relates to a method for cooling and treating heated, rotationally symmetrical bodies made of metallic materials such as steel or steel alloys.
  • the invention further relates to a device for performing this method.
  • Another disadvantage is that the previously known systems and procedures do not cause descaling, especially in the tread area of railway or tram wheels, so that generally there are no uniform heat transfer conditions in the circumferential direction of the tread area with the corresponding effects on inhomogeneous structural and strength properties the circumference of the wheel in question. If the wheel rim is subjected to accelerated cooling in this procedure, the hub of the wheel remains untreated, so that at most a normalization process is used here. All of this leads to corresponding structural and strength gradients in the radial direction in the wheel rim area.
  • the previously known systems are generally time-controlled, that is to say that the coolant volume and / or the coolant pressure and thus essentially also the coolant temperature are unchangeable, that is to say permanently set, so that the structure and strength are influenced of the wheel rim is carried out over a predetermined cooling time.
  • An online temperature measurement or an online temperature-controlled cooling are not known in this context.
  • Desired structural or mechanical properties can therefore only be influenced in an unsatisfactory manner, while residual stresses in the area of the wheel rim can only be influenced, if at all, inaccurately and therefore in an unsatisfactory manner, since the plasticizing processes that decisively determine the internal stresses in the transition area between the cooling wheel rim and the hot one Blade can practically not be checked because only the wheel rim is checked and the structure or the internal stress of the blade are ignored.
  • the invention is based on the object of first creating a method with which the disadvantages of the prior art can be completely eliminated and, moreover, it is possible to specifically influence predetermined areas of the body.

  • the method according to the invention is a functional area-related, defined and reproducible setting of mechanical properties by means of complex cooling processes. These cooling processes are usually for the different volume or Surface areas of the rotationally symmetrical body in question, for example of a wheel, differ.

  • Rule and control variables according to the new procedure are the online measured surface temperature of the body and / or the coolant pressure, and / or the coolant quantity, and / or the coolant stamping (laminar / turbulent), and / or the type of cooling medium (water, air, mixtures) ) and the chronological sequence of the coolant type in an individual coolant circuit.
  • the desired microstructure and thus the mechanical properties can be carried out in a targeted manner when using the method according to the invention, not only in the area of a wheel rim, but in every functional area of the wheel or body.
  • the upstream descaling of the tread or the like results in a uniform surface quality and thus largely uniform heat transfer conditions.
  • Desired residual stresses e.g. B. in the area of the wheel rim can be adjusted according to their height, since the plasticizing processes that determine the residual stress are very specifically influenced in the transition area between cooling and hot material areas, because of the fact that the surfaces of several edge areas are individually controlled in a very controlled manner can.
