Definitions

  • the present invention relates to a method and a device for leveling flat products such as strips, metal sheets or sheets, especially of steel, that one will designate thereafter generally under the name of sheet metal, according to the preamble of claims 1 and 3.
  • Document FR-A-2 334 440 describes a process according to the preamble of claim 1 with the exception of the characteristic relating to the use of adjustable yield compensation means independently from one roll to another.
  • Leveling devices are used in order to remove flatness defects sheets after hot or cold rolling. Indeed, for example after the hot rolling phases (in a cage reversible quarto for sheets or in the finishing train for bands), cooling and packaging, laminated products may have non-developable flatness defects, such as defects called long edges or long center, or developable flatness defects, such as defects hanger or tile. These geometric defects affect visibly the rolled products.
  • the aim of the planing operation is to remove these defects, developable and non-developable, and ensure stability of the sheet after cutting, by removing or at least minimizing constraints internal.
  • the principle of leveling by a leveler of the type concerned with the invention is to submit the sheet in scrolling through a succession of alternating flexions, including the amplitude decreases gradually at the end of the operation.
  • this succession of bending is ensured during the passage of the sheet between leveling rollers staggered and being nested into each other so as to cause said alternating bending, this nesting reducing, in the direction of movement of the sheet, to produce the so-called progressive decrease in amplitude inflections.
  • the strong bends to which the sheet is subjected at the entry of the leveler are required to allow sufficiently laminate the material to remove basically the initial geometry faults not developable.
  • the deformations of alternating bending, combined with the pulling effect caused by the sheet metal drive are sufficiently important, there is plasticization of all fibers of material over the entire width of the sheet.
  • these large deformations generally create a distribution non-homogeneous internal longitudinal stresses (leading to the defect called hanger) and transverse (defect called tile) in the thickness of the sheet.
  • this plasticization is more or less important according to the initial geometry faults.
  • this distribution heterogeneous constraints must be removed, and the intensity of the constraints must be reduced, in a next phase, which is practically achieved by the succession of flexions of decreasing amplitude towards the exit from the dresser.
  • a leveling is really effective when the sheet obtained is perfectly flat before cutting, and the rest after any cutting, which can only result of a gradient of residual internal stresses after the lowest possible leveling. Only a deformation homogeneous sheet over its width provides these lowest residual stress gradients possible.
  • the levelers currently known feature generally, in addition to conventional means for adjusting position of the leveling rollers located on both sides of the sheet metal trajectory, yielding compensation, or counter-bending systems, adjustable to prevent bending of the rollers gliders under the effect of the efforts to which they are submitted during planing.
  • support rollers 9 are placed on a support frame 7 and held in contact with the leveling rollers 5. These are thus supported by the so-called support pebbles, which limit the flexural deformations of the rollers.
  • the glider rollers are fitted swiveling in bearings (not shown in the Figure 1) linked to a frame 3 of each box spring of the leveler (upper bed base 1, lower bed base 2). At minus one of these bases, being adjustable in position, adjusts the spacing of the two sets of rollers gliders 5, while, in each box spring, the rollers of support 9 are linked to the support frame 7, which makes it same part of the box spring, and can only be more or less pressed against the leveling rollers to avoid the deformations of these.
  • a typical system of counter-bending adjustment consists of a set of bias wedges 11 placed between the bed base and the chassis of the support rollers; the relative horizontal displacement of said bias wedges, controlled by a motor 13, leads to press more or less strongly all of the rollers support 9 against the leveling rollers 5 and thus limit the deformation of the latter under the effort of bending of the sheet.
  • Other means of adjusting the against bending such as cylinders, are also known and used to act on the support rollers to ensure offset compensation on all glider rollers a box spring, upper or lower, or both box springs.
  • the present invention aims to solve the problems mentioned above and aims in particular to allow the manufacture and supply of sheets with the smallest flatness defects possible, especially less than 3 mm / m, and do not presenting no risk of occurrence of such defects after delivery to the user, when the latter proceeds to their cutting.
  • the object of the invention is a leveling process for flat metal products such as as sheets, sheets or strips with the features of claim 1.
  • the inventors discovered, as a result in-depth studies of the leveling process carried out in levelers according to the prior art, that the flatness defects that may remain after the operation leveling results in particular from deformation rate different between the different longitudinal fibers of the produced during successive alternate bending to which it is subjected by the leveling rollers.
  • These differences in treatment of the material of the sheet metal across its width cause even when the product seems to plane out of glider, large gradients transverse internal constraints, which manifest themselves later, for example after cutting the sheet, by deformations of the blanks from the sheet, strip or planed sheet.
  • a first cause appeared in existence, in sheet metal laminated before planing, fiber defects, of the type "long edges" or "long center". These faults are not developable, are in principle corrected during first alternate bending performed by the first rollers of the leveler, which must lead to plastic deformations of the material. Due to faults of aforementioned fibers, these deformations do not produce however not the same effect on all fibers, the longest fibers being less plasticized than the shorter fibers, and this results in the appearance of internal stress gradients already mentioned.
  • the alternately flexion of amplitude gradually decreasing then applied to the product by the Glider rollers located downstream are in principle intended to homogenize the state of internal stresses and reduce their intensity.
  • the curves J1, J5 and J2, J6 correspond to the deformations measured in ⁇ m / m by the gauges placed towards the banks
  • the curves J3, J4 correspond to the deformations measured by the gauges located in the center of the sheet.
  • Each peak 21, 23 of different curves corresponds to the passage of the area of sheet fitted with gauges on a leveling roller (respectively 51, 53), as shown diagrammatically in Figure 2, the difference in abscissa between peaks successive corresponding to the distance between the planes vertical axes of two successive rollers.
  • the pics directed downwards correspond to the gauges located on the face of the sheet in contact with the leveling roller concerned, subjected to compression deformation, and the peaks directed upwards correspond to the gauges located on the other side, subject to elongation.
  • the known leveling methods involved a ceding compensation setting identical for all rollers; gold like efforts suffered by the rollers located downstream are less than those suffered by the input rollers due to the least deformations imposed on the product, their own yielding is also less.
  • the yield compensation is identical, in terms of displacement of the support rollers, for all the rollers, this results in either significant yielding, and so excessive deflection, input rollers, in the case of optimal compensation on the rollers output, i.e. excessive counter-bending of the rollers output, in the case of optimal compensation on the input rollers.
  • the process according to the invention makes it possible to adjust the yield compensation for each roll, and therefore ensures the air gap optimal for each pair of rollers, whatever its position in the leveler, and therefore to submit the produced at substantially identical deformations on all its width.
  • the invention also relates to a device for leveling of flat metal products, allowing the setting using the method described above, this device being defined in claim 3.
  • the means of offset compensation include support rollers so-called gliding rollers, pressure means for apply the said rollers to the said rollers, and adjustment means, independent for each roller, of the pressure exerted by said rollers on the rollers.
  • each roll Preferably, several sets of rollers are distributed along the length of each roll, each of these assemblies having means for adjusting the independent pressure.
  • FIGS 5 and 6 illustrate a mode of realization of the leveler according to the invention. Only the upper box spring 1 has been shown, the box spring lower being carried out in a similar manner.
  • planer rollers 51 are mounted in rotation in bearings 61 linked to the frame 63 of the bed base.
  • Each roll is provided with compensation means ceding, consisting of several sets 65 of rollers support, distributed along the length of the rollers. The number of these sets depends on the length of rollers. Preferably, a set of rollers of support is located in the middle of the roller, and another together towards each of its ends. Others roller assemblies can be placed in positions intermediate when the rollers are long, for the leveling of sheets or large sheets.
  • Each set includes two support rollers 67 whose axes are offset on either side of the plane vertical passing through the axis of the roller 51, so as to support this one in the vertical direction, and also to prevent displacement or bending in a plane horizontal.Each pair of rollers 67 is mounted on a support 69, guided vertically in translation on the box spring 1.
  • a jack 71 is placed between the box spring and each support 69 of rollers, for pressing said rollers 67 against roller 51.
  • all the rollers are mounted on a same bed base, and the adjustment of the spacing between the upper rollers and the lower rollers is performed simultaneously for all rollers by adjusting the relative position of the lower bed bases and upper, in spacing and tilting, i.e. in relative inclination so that the air gap between the lower and upper rollers are more important towards the exit of the leveler than towards the entry.
  • the first roller (s) in entry leveler can however be adjusted in position independently of the rollers located downstream, so as to allow adjustment of the amplitude of the first bending deformations, without influencing that of the following rollers.
  • the upper input roller 52 can be mounted on a bed base 1 ', independent of bed base 1 supporting the exit glider rollers, and having its own means adjusting the distance between the roller 52 and the corresponding rollers of the lower base.
  • this first roller 52 is provided with means very powerful ceding compensation in order to correct flatness defects by selective stretching fibers (center or strands), the following rolls ensuring a progressive and homogeneous relaxation in the width of the sheet, made possible by the yield compensation individually adjustable on each roll.
  • the leveler is provided with means for continuously measuring the forces exerted by the product on the rollers or the position of said support rollers or rollers, and means for control of the cylinders according to the measured forces or said measured positions, to adjust during leveling the counter-flexions on each roller.
  • the invention is not limited to the device for leveling which has just been described only as example.
  • the number of rollers, the number of rollers per roller and the relative arrangement of the rollers in relation rollers may be changed without departing from the scope of the invention as claimed.
  • the means for adjusting the counter-bending described above can be replaced by other equivalent means known to those skilled in the art.
  • these means of adjusting the pressure may be common to several sets of support rollers if you wish to reduce the cost of comes back from the machine.
  • a single cylinder in middle position according to the generatrix of a roller and associated with a metal support plate interposed between the jack and the supports 69 may be suitable in this goal.
  • the possibilities for fine adjustment of the counter-flexions are correspondingly smaller, but may be sufficient to some facilities.
