Definitions

  • the invention relates to a system for the heat treatment of metallic annealing material with a distributor for the heating or air or gas. Coolant, the distributor having tubular or slit-shaped nozzles directed against the annealing material which may be located on a transport device, in order to form impact jets.
  • the invention is therefore based on the object of eliminating this deficiency and reducing the expenditure of energy and quantity with comparatively simple means.
  • the invention solves this problem in that the nozzles to enlarge the Distance between the nozzle mouth and annealing material are provided with retractable extensions.
  • the nozzle outlet can thus be brought into the optimum distance from the surface of the annealing material. If the annealing material has a surface shape that deviates from the plane, e.g. by warping or changing the plate thickness, the nozzle outlets can be easily adapted to the shape of the annealing material using the retractable extensions. With these extensions, however, sufficient space for inspection purposes can also be achieved.
  • the extensions can be adjusted together by means of a frame, which is preferably formed from struts, the distance between the outlet opening of the nozzles and the surface of the annealing material being determined both by a measuring device and visually by the operating personnel. In any case, the adjustment is neither time-consuming nor labor-intensive.
  • a narrow free space is left open between the nozzle body and the extension.
  • the nozzles are cheaper to design as openings in the distributor jacket and the extensions to be retractable into the openings.
  • a plate-shaped annealing material 1 is carried out by means of drive rollers 2 in the direction of the arrow through the heat treatment system.
  • a distributor 3 which is supplied with air or gas for heating or cooling and which has pipe nozzles 4 directed against the annealing material 1, which in turn are provided with telescopically displaceable extensions 5.
  • Impact jets for the annealing material surface 1 are formed by the nozzles 4 or the extension 5.
  • the extensions 5 are connected by struts 6 to form a frame which can be adjusted from the outside.
  • Fig. 1 shows the usual position of the extension 5, whereas in Fig. 2 a completely retracted extension 5 is shown.
  • FIG. 3 shows the diagram of a plant for the heat treatment of coils.
  • a motor 8 drives a fan 9 with a guide device 10, which conveys the heating or cooling medium into the distributor space 3, which is again provided with nozzles 4 and extensions 5, the frame formed from the struts 6 having an adjusting device 11.
  • the heating or cooling medium impinging on the workpiece surface, namely a coil of tape 12 is directed back into the distribution space 3 by the fan 9, a heating device 13 being arranged upstream of this.
  • 5 shows the formation of slot-shaped nozzles 4a, the extension 5a being provided with spacers 14.
