Definitions

  • the present invention relates to the treatment lines of steel or aluminum strips using at least one gas or air jet cooling chamber, or a gas or air jet cooling section, such as the heat treatment lines, in particular continuous annealing lines, or such as coating lines, in particular metal or non-metallic coating lines.
  • the subject of the invention is a method for cooling a strip of steel or aluminum moving in a treatment or coating line, in which gas or air jets are sprayed towards each of the moving web faces according to the preamble of claim 1.
  • This process aims to increase the cooling of the band while avoiding vibration phenomena on the band.
  • a vertical cooling chamber of a steel or aluminum strip processing line produced according to the state of the art is constructed according to the principle shown in FIG. figure 1 , on which there is a cooling chamber 4 of a treatment furnace, in which circulates a steel or aluminum strip 1, which is subjected to the action of cooling elements 2 when it passes over upper idler rollers 3 and lower idler rollers 3 '.
  • Strip 1 is cooled in chamber 4 mainly by the cooling elements 2 consisting of gas blowing assemblies at a temperature below the strip temperature.
  • the band 1 is cooled on both sides by the cooling elements 2 located on either side of the line of the pass, and in case of cooling on several lines of pass, said band changes line of pass to each return roller 3 or 3 '.
  • the cooling curve of the strip in the chamber is controlled by the indexing of the different cooling elements 2 or groups of cooling elements operating identically.
  • a vertical cooling section of a steel or aluminum strip processing line produced according to the state of the art is constructed according to the principle shown in FIG. figure 2 , on which is distinguished a vertical cooling section 10, in which circulates a strip 11 which is subjected to the action of cooling elements 12.
  • the strip 11 is cooled in the section mainly by the cooling elements 12 consisting of air blowing assemblies at a temperature below the strip temperature.
  • the theoretical line of the band 11 is determined by the upper idler roll 13 and the lower idler roll 13 '.
  • the strip 11 is cooled on both sides by the cooling elements 12 located on either side of the line of passage.
  • the cooling curve of the strip in the section is controlled by the indexing of the different cooling elements 12 or groups of cooling elements operating identically.
  • the productivity of the cooling chamber or section is determined by the ability to provide cooling heat transfer to reach strip temperatures at the outlet of the cooling chamber or section and the cooling slopes (expressed in ° C / second) that determine the metallurgical quality of the final product.
  • This heat transfer is dependent on the blowing distance between the strip and the cooling system, the geometry of the blowing, and the blowing speed. The heat transfer will also be more effective if the blowing distance is small and / or if the blowing speed is important.
  • Cooling slopes are lower (typically 20 ° C / second) for steels of commercial quality called CQ (Commercial Quality).
  • CQ Common Quality
  • the average thickness of the steels decreases, while the average width of the strips to be treated increases with the optimization of the stamping means.
  • the cooling zone after coating of a hot-dip galvanizing line shown on the figure 3 is also very sensitive to this phenomenon.
  • the thickness of the coating is controlled by spinning in air or nitrogen of the liquid coating. This wringing is generally carried out by a pair of blowing nozzles 23, 23 '.
  • the vertical cooling zone 24 which follows is intended to freeze coating and achieving a temperature at the turn-up baffle roll 25 which is process-compatible, in particular avoiding any trace on the coating.
  • the increase in the capacity of the lines makes the free strand height of the web 21 between the last roller 26 immersed in the molten zinc bath 22 and the tower top baffle roll 25 can exceed 50 meters on large lines. capacity.
  • Aeraulic stabilization systems have also been proposed to replace the aforementioned stabilizing rollers. These systems are relatively efficient and can contribute to cooling, but they are not optimized to favor the exchange coefficient, and therefore to optimize cooling. In addition the energy consumption is relatively important.
  • Another solution is to control the vibrations of the band by adjusting the blowing speed and / or the distance between the band and the blowing elements and / or the blowing flow rate in the event of occurrence of vibrations. This then leads to a limitation of the efficiency of the cooling, and therefore of the performance of the installation.
  • FIG. 4 Another solution illustrated in figure 4 has been proposed to promote lateral flow of the blown gas.
  • This solution consists in arranging blow tubes 31, 31 'on blow boxes 32, 32' located on either side of the band 33 which runs in a direction marked 100.
  • the blowing tubes 31, 31 ' allow and to guide the blowing jets 34, 34 'emitted in a direction which is perpendicular to the plane of the strip 33 scrolling.
  • this system leads to an improvement over simple boxes the holes are not satisfactory, and the band flutations observed in such systems lead either to deterioration of the tubes when the band is thick, or to tape breaks when the band is thin.
  • the simulations of fluid mechanics on industrial geometries show that, when the band 33 is decentered towards one of the two boxes, here the box 32 ', the resultant of the pressures on the band exerts a force F tending to bring even more the strip of said box. The system is therefore unstable, and does not tend to stabilize the band in a pass line centered between the boxes.
  • the simulations of fluid mechanics on industrial geometries show that, when the band 33 is inclined, the resultant of the pressures exerted on the band exerts a torque C, tending to further incline the band and thus to bring the edges of the band closer together caissons.
  • the system is also unstable, and does not tend to stabilize the band in a pass line centered between the boxes.
  • the results of Figures 5 and 6 have been demonstrated by simulation of fluid mechanics software, and by a calculation of the resultant pressures exerted on each side of the strip.
  • the resultant pressure exerted on each side of the strip is the result of positive pressures in areas that are substantially right of the blowing tubes, and depressions at the parts that are not located in line with these tubes.
  • the document US-A-6,054,095 teaches also to incline to the edges of the strip the blowing tubes equipping the boxes, but to have a better homogeneity of the temperature of the strip, so without worrying about the stability of the scrolling of said strip.
  • the document US-A-4,673,447 discloses the use of blowholes with holes, said holes being formed in a thick plate to have an inclination of gas jets. It should be noted that the jets are inclined not towards the edges, but on the contrary towards a median plane, symmetrically with respect to said plane. It is therefore rather a simple stabilizing pad.
  • EP-A-1,108,795 describes a variant of the preceding techniques, in which one also uses boxes with straight blow tubes (perpendicular to the plane of the strip). In fact, the aim is only to modify the intensity of cooling by varying the length of the tubes, which are chosen shorter at the edges of the strip.
  • EP-A-1,029,933 discloses another variant with bladed nozzle boxes.
  • the transverse blades produce no inclined jets, and the boxes do not allow to organize a recovery of the blowing gas perpendicular to the strip, as already mentioned above.
  • FIGS. Figures 7 and 8 a commonly used solution is shown in FIGS. Figures 7 and 8 (the figure 8 being a section according to VIII-VIII of the figure 7 ).
  • This solution consists in using tubular blowing nozzles 41 of axis 48, having bottoms 46 and a gas inlet 47, said nozzles being pierced with several circular holes 42, which are oblong or slit-shaped, allowing blowing jets 45 on the strip 43 scrolling in the direction 100, in a direction normal to the plane of the strip.
  • the document EP 1 067 204 A1 discloses a solution for suppressing vibrations by adjusting the pressure and / or the flow rate of gas blown in the transverse direction of the strip.
  • this method has two major disadvantages.
  • the strip may be made to be not parallel to the blowing devices, thus reducing the distance between the strip and the device, and increasing the risks of contact.
  • the cooling capacity is not maximum, and the reduction of the speed and / or the pressure on one side can not be compensated by an increase in the speed or pressure of the jets on the other side if the speed or blowing capacity limits have already been reached.
  • the aim of the invention is to propose a cooling method that optimizes both the thermal and a somehowlic aspects, that is to say maximizing the cooling, while minimizing the vibrations or the strip offsets by a self-centering effect tending to reduce the band in an ideal pass line when it is deported or when it is rotated relative to its theoretical line.
  • the fundamental principles of the approach of the invention are to combine the advantages of a minimized containment, and a limitation of the flow of gases in a plane parallel to the band with optimized blowing by directed jets ensuring both cooling and stability of the band.
  • blow-through nozzles pierced with holes (depending on the Figures 7 and 8 ) which leave substantial containment between the band and the nozzles.
  • the usually small thickness of the blowing nozzles makes it impossible to direct the jets by simple drilling or machining of the blast nozzles.
  • the aforementioned technical problem is solved according to the invention by a cooling method of the aforementioned type, wherein the gas or air jets are emitted from blowing tubes fitted to tubular nozzles arranged remotely one of the other transversely to the direction of movement of the strip, said jets being directed towards the relevant face of the strip by being inclined both substantially towards the edges of said strip in a plane perpendicular to the plane of the strip and to the direction moving said strip, and upstream or downstream of the strip in a plane perpendicular to the plane of the strip and parallel to the direction of movement of said strip, according to the characterizing part of claim 1.
  • the jets of gas or air emitted from the same tubular nozzle are inclined upstream and downstream of the strip. We thus obtain a better blowing efficiency for the same number of tubular nozzles.
  • the distance between two adjacent tubular nozzles on the same side of the strip is chosen such that the points of impact of the gas or air jets on the strip are substantially equidistant in a direction parallel to the direction of movement of said band. This is very favorable for the stability of the band during the scrolling thereof.
  • the jets of gas or air emitted from the same tubular nozzle are inclined essentially towards the edges of the strip in such a way that the points of impact of said jets on said strip are substantially equidistant in a direction perpendicular to the direction of movement of the strip.
  • the jets of gas or air emitted from the same tubular nozzle are inclined essentially towards the edges of the strip at an increasing inclination, from the center line of the strip towards the edges of said strip, from about 0 ° to an angle less than 15 °.
  • the jets of gas or air are organized to have a substantially constant jet distance regardless of their inclination.

  • Hollow discharge tubes 52 are fixed on the tubular nozzles 51. These tubes are arranged in one or more rows. The arrangement and the row number of the blowing tubes must be provided in order to have a mesh of the points of impact on the strip which is substantially equidistant in order to optimize the cooling and to limit the thermomechanical stresses exerted on the strip.

  • the blow tubes 52 are inclined both substantially to the edges of the band 53 in a plane perpendicular to the plane of the band and to the direction of movement of said band (as is visible on the figure 10 ), and upstream or downstream of the band 53 (with reference to the direction of travel) in a plane P perpendicular to the plane of the strip and parallel to the direction 100 of displacement of said strip (as is visible on the figure 9 ).
  • blowing tubes 52 near the center line LM of the strip 53, may emit jets which are perpendicular to the plane of the strip, the great majority of blast tubes 52 nevertheless having an inclination at an angle ⁇ with respect to the normal to the plane of the strip.

This makes it possible to channel the residual flow of gas (that is to say the non-evacuated flow to a rear direction perpendicular to the plane of the strip after heat exchange with said strip) in preferential directions towards the band edges tending to stabilize. said band.
  • One of the cooling performance parameters is the blowing distance, that is the distance of the emitted jet 58, between the free end 54 of a tube 52 and the corresponding point of impact 55 on the strip, for the jet emitted by this tube.

This results in obtaining a regular and optimized mesh of the impact points of the blowing 55. This distance d then allows an optimal recovery of the gases, in a direction substantially normal to the plane of the band, which has the effect of reducing the depressions may exist between the impact zones.
