Definitions

  • the present invention relates to a method and an apparatus for heating or cooling quenching media for the heat treatment of components.
  • the quench baths are electrically heated, e.g. by means of resistance heating.
  • the cooling takes place through a water circuit.
  • Air cooling is also possible, however, too expensive, since large cooling surfaces are required.
  • the object of the present invention is to propose a method and a device for heating or cooling quenching media of the type mentioned at the outset, which is more economical and easier to handle and is less technically complex and therefore less prone to failure than the known methods.
  • the figure shows a schematic arrangement of the device for heating or cooling a quench bath.
  • a quenching bath 1 is filled with a quenching medium 2, preferably oil.
  • the quenching bath 1 is connected to a conventional heat exchanger unit 4 via a discharge and supply pipe 3.
  • the tube 3 is arranged in a spiral along the inner wall of the outer surface of the bath, so that the heating or cooling coils 3a extend from the bottom of the bath to below the bath level.
  • the heat transfer oil is cooled down until an equalization has taken place and the target temperature of the bath is reached again.
  • the cooling can take place in a known manner via a device for water cooling the heat transfer oil (not shown in the figure), in which a cooling liquid circulates in a closed circuit.
