Definitions

  • the invention relates generally to industrial surface treatment techniques, in particular applied to the longitudinal and transverse control of the thickness of a hot-rolled metal coating on a steel strip in a continuous galvanizing plant.
  • the invention more precisely relates to a method for continuously depositing a coating on a strip support of a determined width with convergence, towards at least one target value, of the thickness of this coating on the surface of the coating.
  • this method comprising a deposition operation in which the support is driven, in a longitudinal direction of travel perpendicular to its width, in an installation comprising a set of actuators controlled by respective control signals each comprising at least one component, each actuator being able to act on the thickness of the coating, depending on the width of the support, depending on the control signal it receives.
  • the invention will be mainly considered in its preferred application to galvanization, in which the support is formed of a steel strip and the coating of a layer of zinc or a zinc alloy, it being understood, however, that the The invention is applicable to other industrial processes for continuously depositing a coating on a support.
  • the REV coating thickness has mainly an impact on welding, particularly by resistance.
  • High thicknesses require strong welding currents that adversely affect the life of the electrodes.
  • variations in thickness from one weld to another can lead to defects or require constant adjustments of the welding parameters.
  • the figure 2 shows the typical arrangement of air-drying on a continuous galvanizing line.
  • the SUPP tape carrier routed through an incoming CAF channel of the furnace, plunges into a Zn zinc bath or zinc alloy contained in a PT tank or "pot", is deflected onto a RDFL bottom baffle roll. , and passes, with its REV coating in front of ESSR spin drying ramps that flow back to the pot PT surplus zinc or still liquid alloy.
  • the patent JP 5-117832 identifies the main operating variables of this technique, namely ( Figure 12a of figure 12 ) the speed of the air jet that depends on the pressure of the compressed air supplied to the ESSR wiper and the distance "e” between the ESSR1 and ESSR2 lips of this wiper, the distance "d” between the lips the wiper and the SUPP tape support to be coated, as well as the scroll speed of the SUPP support.
  • the experiment has also made it possible to identify more exhaustively the operating variables as well as the operating disturbances undergone.
  • These operating variables are typically the required coating thickness on each side of the web, the web format - i.e., its width and thickness for continuous deposition on a web of tape. non-predetermined length - the running speed of the web, and the traction of the web in the coating area.
  • the operating disturbances are essentially related to the behavior of the band in the spinning zone and include the improper centering of the band in the space between the two wipers, the inclination of the band with respect to the wipers, and the transverse deflection. of the band, still called “tile” or “crossbow” by the skilled person.
  • the figure 4 composed of FIGS. 4a to 4c, shows the effect of these defects on the thickness of the REV coating at the exit of the ESSR wipers.
  • the inclination of the strip with respect to the ESSR wipers leads, on the cross section of the strip, to a REV coating thickness gradient symmetrical with respect to the center of this section (FIG.

  • ACT actuators
  • the control of the homogeneity of the REV coating thickness in the transverse direction of the SUPP strip uses several means.
  • This homogeneity can first be controlled by a multiplicity of actuators ensuring the position adjustment of ESSR wipers.
  • the figure 6 shows that the combination of the individual actions performed by four actuators (ACTx1 ACTx4) not only allows to center the axis of the band between the ESSR sweepers but also to correct the variations of transverse inclination of the band.
  • the homogeneity of the coating thickness REV in the transverse direction of the SUPP strip is also liable to be controlled by the deformation of the wipers' lips, as is for example the patent EP 0 566 497 , which describes a device for adjusting the distance between the two lips of each of the wipers in order to vary the thickness of the air gap.
  • Multiple actuators such as ACT1, ACT3, ACT5 thus make it possible to vary this thickness from one end to the other of each ESSR wringer as schematically shown in FIG. figure 7 on which are represented several thicknesses of blade, such as e1 and e5.
  • the homogeneity of the coating thickness REV in the transverse direction of the SUPP strip can be further controlled by the position of a roll "anti-tile” RAT, also called “anti-crossbow” roll, such a roll being disposed between the RDFL bottom deflection roll and a roll of RLP pass line.
  • a roll "anti-tile” RAT also called “anti-crossbow” roll
  • the transverse deflection or "tile" of the support SUPP strip is as much as possible corrected by traction of this support in the furnace located upstream of the coating bath, there is still a residual defect of flatness more or less marked in the galvanizing bath.
  • the residual arrow just below the ESSRs may be at least elastically corrected by horizontal movement of the anti-crossbow roll and / or the RDFL bottom roll with respect to the roll line roll RLP.
  • This known process has been described in several patents, and in particular in the patent JP 8-260122 .
  • the experiment has shown, as indicated above, that the vibrations and the effect of certain undulations could be limited by keeping the band a controlled arrow which gives it a certain longitudinal stiffness.
