- the invention also relates to an installation comprising at least one such reservoir and its use.
- the refrigerant can be liquid. Long-used liquid lead is now increasingly being replaced by water or preferably by certain polymer solutions. After quenching, the change in crystal structure which occurs is exothermic, which requires cooling or several successive controlled coolingings to reach the appropriate temperature, and to obtain a product having an adequate microsfrucfure.
- this bu ⁇ in particular, after the exit of the wires from the quenching bath, an immersion of the latter in a cooling bath has already been provided, don ⁇ the length can be adjusted according to the diameter of the wires e ⁇ of their desired tensile strength (see WO 2018/130499). Between these two static baths e ⁇ disclosed very schematically, the wires pass through an air space where they are repeatedly bent in an undesirable manner.
- the object of the present invention is to provide an overflow reservoir for a heat exchange liquid bath which is movable in order to be able to treat an elongated metallic article moving in a fluid, in an adjustable position at loose moment to precisely modify its position. temperature in another, e ⁇ this in a simple and economical way.
- a main object of the invention is to provide a simple, efficient and inexpensive solution for the circulation of the heat exchange liquid between the underlying basin and this reservoir which can be moved at any time.

- heat exchange liquid By heat exchange liquid, it tau ⁇ mean according to the invention, a refrigerant liquid or a heating liquid which exert a temperature exchange with the elongated moving metal article.
- the tank at overflow becomes self-contained and its position can be adjusted with maximum flexibility over the underlying basin. All the elements necessary for the operation of the reservoir accompany it in any position and the liquid relationship between the underlying basin and the reservoir is particularly simplified. In addition, the position of the circulation system does not in any way encumber the space of the reservoir necessary for the movement of the elongated articles to be treated.
- the circulation system comprises a propellant body having a lower end opening into the heat exchange liquid of the underlying basin e ⁇ an upper end fixed to the reservoir, on the outside thereof, a rotary motor arranged at the upper end of the thruster body, a propeller which is arranged inside the lower end of the thruster body e ⁇ which is rotated by the rotary motor, so as to propel towards the top the heat exchange liquid of the underlying basin in which it is immersed, e ⁇ a liquid communication between the propellant body and said inlet of the heat exchange liquid reservoir.
- the propellant body can thus take the form of a tube fixed laterally to the reservoir e ⁇ capable of propelling upwards, into the reservoir, the heat exchange liquid located in the underlying basin just below the reservoir.
- said guiding means are rails e ⁇ the tank es ⁇ provided with rolling or sliding means capable of cooperating with said rails to allow movement of the tank on these rails. These can cross the underlying basin over its entire length and thus allow the reservoir to move over its entire length.
- the reservoir es ⁇ provided with a handle, whether it is at the level of the reservoir itself, or of the circulation system for example.
- a simple push or pull the position of the tank in the direction of travel can be easily changed.
- This movement can also be controlled by motor.
- the reservoir is, as indicated above, provided with upstream and downstream dams.
- This is an overflow tank.
- said at least one upstream dam and said at least one downstream dam are arranged with respect to each other at an adjustable distance. This allows length adjustment of the tank bath. Not only can the reservoir be placed precisely in the travel path of elongated metal articles, but the heat exchange time in the reservoir can also be adjusted. Such adjustments are important depending on the articles to be treated, in particular their section.
- the reservoir is divided into compartments separated by longitudinal partitions parallel to the direction of travel and each compartment has an aforementioned upstream dam ef / or a aforesaid downstream dam, movable independently.
- each compartment has an aforementioned upstream dam ef / or a aforesaid downstream dam, movable independently.
- the invention also relates to a heat exchange installation between elongated moving metal articles e ⁇ a heat exchange liquid, comprising at least one reservoir according to the invention.
- This installation may include several above-mentioned tanks supported above the same underlying basin on the same guide means, independently movable. These tanks can receive in succession the same elongated metal articles e ⁇ thus allowing a staged cooling or a staged heating of these.
- G installation comprises several mutually parallel guide means which each support, above the same underlying basin, at least one aforesaid reservoir independently movable.
- these must be able to be treated in different positions of the scrolling path and for different times, while they possibly have different speeds, which allows this embodiment according to the invention.
- the arrangement of a reservoir and their successions allow the elongated metal articles to scroll without inflection during all the heat exchange.
- the invention also relates to a use of an installation according to the invention for the controlled cooling or the controlled heating of said elongated moving metal articles.
- an installation according to the invention for the controlled cooling or the controlled heating of said elongated moving metal articles.
- Other details e ⁇ particularities of the invention will emerge from the appended figures which illustrate, in a non-limiting manner, examples of tanks e ⁇ of installations according to the invention.
- FIG. 1 represents a perspective view, transparent, of a mobile tank according to the invention.
- FIG. 2 represents a perspective view of the same reservoir arranged in an underlying basin.
- FIG. 3 represents a view in section along the line III - III of FIG. 2.
- FIG. 4 represents in perspective an alternative embodiment of a mobile tank according to the invention.
- FIG. 5 represents a top view of a particular embodiment of an installation according to the invention.
- the tank 1 for a heat exchange liquid bath according to the invention which is represented in FIGS. 1 to 3, comprises a bottom 2 e ⁇ two side walls 3 e ⁇ 4 parallel to the direction 5 of movement of the wires 19
- the wall 3 is also provided with a flange 21.
- An upstream dam 6 is provided at the entry of the wires into the reservoir, in the example illustrated in the form of a cylinder on which the scrolling wire (s) rest, ef a downstream barrier 7 is provided at a distance from the dam upstream 6, in this ⁇ example illustrated in the form of an element with a triangular section to the sum ⁇ of which the scrolling son (s) are ⁇ supported.
- the heat exchange liquid is contained in tank 1 between the dams over which it overflows towards the amon ⁇ e ⁇ downstream as represented by arrows in FIG. 3.
- the reservoir according to the invention is called an overflow reservoir.
- the level of heat exchange liquid 16 present in the tank 1 is shown symbolically in this figure 3.
- the reservoir 1 is ⁇ provided with rollers 8 which make it possible to support it in a movable manner on guide means parallel to the direction of travel 5 of the son.
- the guide means are formed by rails 9 which are arranged in a basin 10 underlying the tank 1.
- the heat exchange liquid which overflows from the upstream dams 6 e ⁇ downstream 7 is ⁇ collected directly in the underlying basin 10. This is ⁇ fitted with a clean current heat exchanger, not shown, which makes it possible to maintain at a constant predetermined temperature the liquid of this basin.
- An inlet 1 1 for supplying the heat exchange liquid into the reservoir is provided, in the case illustrated, in the side wall 3 of the reservoir.
- a circulation system 12 is ⁇ fixedly attached to the mobile tank 1 on the outside thereof. It is therefore fully movable with it, inside the underlying basin 10. All the elements of this circulation system 12 are moved with the mobile tank when it changes its position on the rails guide 9. The autonomy of the tank is therefore total.
- the circulation system 12 brings the heat exchange liquid to the inlet 11 directly from the underlying basin 10.
- the circulation system 12 comprises a propellant body 13 having a lower end opening into the heat exchange liquid of the underlying basin 10 (see FIG. 3 where the level 20 of the heat exchange liquid es ⁇ represented symbolically).
- the thruster body 13 supports a rotary motor 14 which drives in rotation a propeller 15 arranged inside the lower end of the thruster body 13.
- the propeller 15 propels the heat exchange liquid upwards from the underlying basin in which it is immersed, so as to bring it to a communication for liquid 17 between the propellant body 13 e ⁇ the inlet 11 of the tank 1.
- the tank can be fitted with at least one handle, as shown in figure 4 at 23, which allows manual movement of the tank 1 on the guide rails 9.
- the downstream dam 7 is arranged in a movable manner relative to the upstream dam 6.
- a rack 18 extends in the center of the reservoir 1 e ⁇ allows the arrangement of the downstream dam 7 in an adjustable position, for example near the upstream dam 6, as shown in Figure 2, or at a greater distance from this upstream dam 6, as shown in Figures 1 e ⁇ 3.
- This arrangement makes it possible to adjust the length of the bath according to the threads to be treated e ⁇ of the properties that one wishes to obtain for the products.
- the tank 1 es ⁇ divided into three longitudinal compartments separated by longitudinal partitions 24, which are ⁇ parallel to the direction of travel 5 of the son.
- Each compartment has an independent downstream barrier 7, adjustable on a rack 18.
- several wires can pass by submerged in the heat exchange liquid over different bath lengths.
- the wires, which run through the compartment shown on the left are submerged over a longer bath length than the wires running through the other two compartments.
- each compartment has an independent upstream dam, possibly adjustable in position relative to the downstream dam.
- the reservoirs 1 and G have been moved on the guide means so that the wires 19 e ⁇ 19 'are treated by the heat exchange liquid, during of the scroll, at a different location in the basin 10. Furthermore the spacing between the dam 7 e ⁇ the dam 6 is greater in the reservoir 1 than between the dam 7 'e ⁇ the 6 'dam in reservoir G.
- wires 19 and 19 ' run at the same speed in both tanks, wires 19 are treated later than wires 19' and the treatment time is longer in tank 1 than in tank G But by this flexible and adjustable location of the reservoirs with respect to each other and thanks to the modifiable arrangement of the distance between the upstream and downstream dams of the two reservoirs, it is possible to provide identical or different treatments, for identical or different times, for threads moving at identical or different speeds.
- the installation provided is therefore very flexible and allows a wide variation in the treatment of the threads which pass, while being particularly easy to operate with particularly autonomous mobile tanks.
- wires 19 or 19 ' are treated by several successive reservoirs above the same underlying basin 10, these reservoirs being arranged in succession on the same guide means and in an independently movable manner.
