Definitions

  • the present invention relates to a method and an installation for the treatment of coated or uncoated metal parts and, in particular but not exclusively, of galvanized scaffolding elements.
  • the cleaning operation is also desirable for the cleaning operation to be accompanied by a reloading operation of the part made of protective material thereof.
  • An object of the present invention is to provide a method and an installation which makes it possible to simultaneously clean the part if it is dirty or dirty parts of the part and reload metallic parts coated or not, in particular galvanized, for example scaffolding elements, which is simple to implement and inexpensive while being effective.
  • the method of treating coated or uncoated metal parts according to the invention is characterized in that it comprises the step of subjecting, for a predetermined period, said part to a jet of particles at room temperature at high speed of a metal chosen from the group comprising zinc and aluminum in such a way that the cleaning of said part is simultaneously obtained if it contains dirt and the formation of a very thin adherent layer of zinc or aluminum.
  • the metal is zinc and the particles have dimensions less than or equal to 1 mm.
  • the particles have a speed at least equal to 50 m / s.
  • the invention also relates to an installation for treating coated or uncoated metal parts, which is characterized in that it comprises means for placing said parts to be treated in an enclosure and means for subjecting said parts in said enclosure to a jet of particles. at high speed of a metal chosen from the group comprising aluminum and zinc.
  • the particles are zinc particles whose dimensions are less than or equal to 1 mm.
  • the installation comprises a conveyor which makes it possible to move the parts to be treated in said enclosure at a substantially constant speed.
  • FIG. 5 there is shown in section the surface of a part P, for example an element of galvanized steel scaffolding.
  • An outer layer C1 has been found, the zinc content of which decreases from the periphery towards the interior of the part and the part C2 proper of steel.
  • the thickness of the layer C1 is conventionally of the order of 70 microns.
  • this cold zinc plating process could be qualified given the relatively reduced temperature.
  • the projection is carried out in such a way that the rise in temperature of the room is a few tens of degrees Celsius. Preferably, this temperature is at most equal to 60 ° C.
  • a part is thus obtained which is not only clean but which has also been recharged, for example made of zinc. The part must be subjected to the projection of particles for a period of at least 1.5 minutes.
  • This installation is arranged in a hall. It essentially comprises a conveyor 10 which makes it possible to move at a controlled speed, for example of the order of 2 meters per minute, of the parts to be treated.
  • the conveyor moves in front of a loading area 12. It passes through a protective and processing enclosure or blasting tunnel 14 and passes in front of an unloading area 16.
  • the boxes 15 and 17 also containing the blasting turbines are shown.
  • Figure 2 shows an embodiment of the conveyor.
  • the horizontal support rail 18 has been shown and poles suspended by rollers 22 from the rail and driven for example by a chain system 24.
  • the poles 20 for example have nine hooking elements 26 parts to be treated 28.
  • the distance between the poles 20 is of course adapted to the length of the parts to be treated.
  • the protective enclosure 14 or tunnel in which the blasting is carried out comprises on its floor a trench 30 for recovering the blasting particles and a worm conveyor 32 for recovering these particles. Once dusted, the blasting particles can be recycled.
  • the walls 32 and 34 of the treatment chamber 14 are shown schematically, as well as eight electric turbines each equipped with an electric motor making it possible to make jets of blasting particles in such a way that all of the 28 parts passing through the enclosure is suitably subjected to the jet of particles.
  • the turbine nozzles are oriented in such a way that all the suspended parts are subjected to shot blasting. In Figure 4, only the four turbines 36, 38, 40 and 42 are visible.
  • the blasting particles are made of zinc or aluminum.
  • the particles have dimensions less than or equal to 1 mm.
  • these particles are obtained by cutting a zinc wire 0.7 mm in diameter. It can also be zinc balls whose diameter is between 0.6 and 1 mm.
  • each of the eight turbines delivers about 140 kg / min of zinc particles which are emitted with an exit speed of the order of 50 meters per second.
  • the speed of movement of the conveyor and therefore the speed of movement of the parts in the enclosure 14 is of the order of 2 meters per minute so that the exposure time is at least equal to 1.5 minutes.
  • the process is especially well suited for carrying out in a single operation the cleaning of the parts and their recharging. It goes without saying, however, that the invention would not be departed from if the process were applied to initially clean parts in order to reload them with a layer of reduced thickness of zinc or aluminum.
