Definitions
- the subject of the present invention is a method for the treatment of coated or uncoated metal parts and, in particular but not exclusively, of galvanized scaffolding elements.
- Document BR-A-8 201 279 describes a process for treating coated or uncoated metal parts, comprising a step of subjecting said part, for a predetermined time, to a high speed jet of particles at room temperature, whereby one obtains simultaneously cleaning the part when it has dirt and the formation of an adherent surface layer of reduced thickness consisting of zinc.
- the cleaning operation is accompanied by a reloading operation of the material part to protect it.
- An object of the present invention is to provide a method which allows simultaneous cleaning of the piece if dirty or dirty parts of the piece and reloading of coated or uncoated metal parts, in particular galvanized, by example of scaffolding elements, which is of simple implementation and inexpensive while being effective.
- the parts processing process metallic coated or not according to the invention comprises the features contained in claim 1.
- 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.
- FIG. 5 there is shown in section the surface of a part P, for example an element of galvanized steel scaffolding.
- a part P for example an element of galvanized steel scaffolding.
- the thickness of the layer C 1 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 duration at least equal to 1.5 minutes.
- FIG. 1 we will describe the whole of the treatment facility.
- This installation is arranged in a lobby. It essentially comprises a conveyor 10 which allows move at a controlled speed, for example of the order of 2 meters at the minute, of the parts to be treated.
- the conveyor moves in front of an area of loading 12. It crosses a protective and processing enclosure or blasting tunnel 14 and passes in front of an unloading area 16. Also shown are the boxes 15 and 17 containing the blasting turbines.
- Figure 2 shows an embodiment of the conveyor.
- the horizontal support rail 18 and hanging poles by rollers 22 to the rail and driven for example by a system with chain 24.
- the poles 20 include for example nine hooking elements 26 of the parts to treat 28.
- the distance between the poles 20 is of course adapted to the length of the parts to be treated.
- the enclosure of protection 14 or tunnel in which the blasting is carried out comprises on its soil a trench 30 for recovering blasting particles and a worm conveyor 32 for recovering these particles. A once dusted, the blasting particles can be recycled.
- the turbine nozzles are oriented in such a way that all the suspended parts are subjected to shot blasting.
- 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 0.7 mm diameter zinc wire. It could be also zinc balls whose diameter is between 0.6 and 1 mm.
- each of the eight turbines delivers around 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 duration exposure is at least 1.5 minutes.
- the process is specially well suited for carrying out cleaning the parts and reloading them in a single operation. he It goes without saying, however, that the invention would not be departed from if the process was applied to initially clean parts in order to recharge them a layer of reduced thickness of zinc or aluminum.
