Definitions

  • the present invention relates to a metal strip planer according to the preamble of claim 1.
  • a metal strip planer has a property of correcting flatness defects, for example by means of two upper and lower rows of upper and lower rollers respectively, the upper and lower rollers having parallel, offset axes. longitudinally in a bandpass line direction and also offset in height, so as to determine, by nesting rollers, a corrugated path of the band between said rollers.
  • this type of planer makes it possible to impose an elongation of the strands of tape to make it flatter.
  • said planer may include at its output a second so-called multi-roll type module, whose main property is to reduce residual stresses of the metal strip.
  • the metal strip has mainly mechanical stresses having a strong asymmetry in intensity. depending on the thickness of the product and with respect to at least one neutral fiber of the strip.
  • these residual stresses hereinafter referred to as asymmetrical, persist in disfavor with the required quality of planar product.
  • Figure 1 presents a typical example of asymmetric residual stress profile (c) according to the thickness (e) of strip (B) such that after a planing step according to the state of the art.
  • the stress value is zero at the level of at least one neutral fiber (fn), the said neutral fiber being here spaced from a so-called "center of strip” fiber (cb) located in the middle of the strip thickness.
  • center of strip fiber cb
  • Figure 2 presents an optimized residual stress profile targeted by the invention, in that the asymmetry of the profile according to figure 1 tends to be corrected by a rebalancing of positive and negative asymmetric constraints. Such a rebalance must result in a symmetrical stress profile with respect to the band center and whose distribution of (c) positive and negative stresses is as balanced as possible.
  • An object of the present invention is to provide a metal strip planer capable of at least compensating for an imbalance, in particular asymmetric, of distribution of residual stresses in the thickness of the flat strip, in particular for steels with a high elastic limit.
  • a metal strip planer is thus proposed through the features of claim 1.
  • a major advantage of the nesting profile at least three nonlinear type deviations makes it possible to better distribute residual stresses in the thickness of the planar strip, on the model of the figure 2 , contrary to known profiles of linear type which mainly have a resorbant planarizing effect of symmetrical type stresses on the thickness of the band to be hovered and therefore can not rebalance an asymmetric stress.
  • Figure 4 present according to figure 3 the said deviations having a profile (in solid lines) of nonlinear imbrication values (Imbr) of type of either convex or concave with respect to a profile (in dotted lines) of linear nesting values (Imbr_lin) in the direction of pass line (rolls 1 to 16 in this case).
  • the two upper rollers and the two lower rollers are arranged (1, 2, 3, 4) in a first leveling assembly (pl1) comprising for each of the rollers a vertical individual adjustment (v1, v2, v3, v4) with respect to a frame, a beam, a cassette or any other holding element included in the planer for this purpose.
  • the adjustment of at least one of the rollers comprises at least one jack.
  • the first rollers of the planer included in the first leveling assembly (pl1) make it possible in principle to ensure most of the elongation of the strip to correct flatness defects and stresses.
  • the planer may additionally comprise at least one second leveling assembly (pl2) respectively formed by an upper cassette (C1) and a lower cassette (C2) of multi-roll type planer (5, 6, 7, 8, ... ).
  • This configuration is particularly suitable for leveling so-called "tinplate” steels, for example suitable for the manufacture of metal packaging.
  • At least one of the cassettes (C1, C2) of the second leveling assembly (pl2) is inclined by vertical displacement means (v2hg, v2hd, v2bg, v2bd), so that the cassettes are arranged at an open angle in a vertical plane in the direction of the pass.
  • Figures 5 to 7 finally present a second and a third embodiment of the planer according to the invention.
  • the second embodiment of the planer according to the invention provides that the planer is composed only of the second set of planing multi-roller type (first set of planing absent or inactive).
  • This type of multi-roll planer generally comprises a high number of rollers (15 or more), and has the advantage of being able to absorb large defects of flatness and stress.
  • the profile of non-linear nesting values is applied to at least four rollers of the second planing set (p12), for example, by means of the two upper rollers (5, 7) and the two lower rollers ( 6, 8) which are arranged in (at least) the second leveling assembly (pl2) respectively formed by an upper cassette (C1) and a lower cassette (C2) of multi-roll type planer, with at least one of said cassettes comprising for each of the rollers a vertical individual adjustment (r5, r7; r6, r8, ...) of the rolls with respect to the cassettes, ideally the adjustment comprising at least one actuator of mechanical type or servomotor.
  • Figure 6 presents an example of a profile of nonlinear imbrication values (Imbr) of convex form here and applied to the rollers (5, 6, 7, 8, etc.) of the only second planar assembly (pl2) presented in FIG. figure 5 for this second embodiment, the first planing set being not present or inactive.
  • the third embodiment of the planer according to the invention finally provides that the planer is again composed of the first and second sets of planing (pl1, pl2).
  • the planer is again composed of the first and second sets of planing (pl1, pl2).
  • at least the two upper rollers and two lower rollers connected to the profile of non-linear nesting values are distributed or distributed in the first set and in the second set.
  • rollers of the second planing assembly made it possible in the state of the art to limit the residual stresses generated by linear and decreasing planar nesting to compensate for stresses induced in the product
  • the application of non-linear nesting value profiles (convex and / or concave) according to figure 5 around said linear profiles make it very advantageous to compensate additionally for asymmetries of stress in the thickness of the product.
  • said first rollers (in the bandpass direction) of the second planar assembly (p12) are arranged under non-linear nesting values of concave or convex shape, said non-nesting nesting values being Linear values are greater than the linear nesting values (Imbr_lin).
  • Such an advantageous profile of non-linear nesting values is explicitly represented at Figures 6 and 7 .
