Definitions

  • the present invention relates to an installation for cooling a bar or a metal wire, disposed at the outlet of a rolling or drawing installation or following a heat treatment as well as to its use.
  • Known cooling systems have in common the fact of circulating water around the product, parallel to it. They differ from each other in the way of supplying the cooling fluid, namely water or a water / air mixture, possibly under pressure in a tube in which the product to be cooled also circulates. Mention may also be made of the central radial supply, the cooling tube being able to be embedded in a cooling liquid, for example water or to be arranged in a jacket with cooling liquid, the evacuation being always essentially axial.
  • the present invention aims to provide an installation for cooling a bar or a metal wire, intended to be arranged at the outlet of a rolling or wire drawing installation or following a heat treatment installation, which does not have the drawbacks of known cooling installations.
  • the cooling installation comprises a horizontal tube in which the wire or the bar to be cooled circulates and which has a first series of holes distributed over the length of said tube, this first series of holes being intended for the supply. in cooling fluid and connected exclusively to means allowing this supply, and a second series of holes distributed over the length of said tube intended for the evacuation of the cooling fluid and connected exclusively to means allowing this evacuation.
  • the installation has only two series of holes, the second series of holes being arranged essentially opposite the first series of holes.
  • the cooling fluid is advantageously supplied from below, it that is to say through the first series of holes arranged at the bottom of said tube.
  • the section of the cooling tube is notably reduced for a given type of product to be cooled, compared to the state of the art. Indeed, it is advantageous to use a cooling tube whose internal diameter is at most equal to 1.5 x the diameter of the wire to be cooled.
  • the holes of a series of holes are arranged opposite the holes of the other series.
  • the holes of a series are distributed on a generatrix of the surface of the tube.
  • the number of holes in the second series is lower or higher than the number of holes in the first series.
  • the cooling installation comprises a single tube.
  • the cooling fluid is advantageously water, but it is also possible to provide a water / air mixture and / or any other fluid or mixture deposited on the product.
  • An advantage of the present invention lies in the fact that the product to be cooled is in continuous contact with cold water, the exchanges are therefore the best possible at all points and the water line is the shortest possible. Even using a low pressure water supply, the installation according to the present invention allows very tight guidance of the product to be cooled in the tube, thus avoiding the risk of buckling while making the most of the thrust it undergoes. .
  • cooling tube 1 according to the present invention.
  • Said tube 1 is open at both ends 3 and 5 and is intended for the passage of a wire or a metal bar to be cooled (not shown).
  • Said tube is provided with a first series of holes 7 distributed over its entire length, and with a second series of holes 9 also distributed over the entire length of tube 1.
  • the holes 9 are arranged opposite the holes 7 and said first series of holes has a number of holes substantially equal to that of said second series (9).
  • a supply manifold 11 is arranged at the bottom of the tube 1, for a uniformly distributed supply of the cooling fluid, in this case water, over the entire length of the tube 1 through the holes 7 of said first series.
  • the tube 1 fitted with a supply manifold can also be housed in a suitable reservoir 13 intended to recover the fluid discharged through the holes 9 of said second series. It is obvious that the fluid thus collected can be recycled adequately.
