Definitions

  • the present invention relates to a method for regulating in real time a leveler intended for planing metal strips in coil or in coil, such as steel strips or directly plates or sheets.
  • the invention applies on the one hand to the leveling of the metal strips intended to be cut at the exit from the leveler, so as to obtain plates or sheets of a determined length L, and on the other hand to the leveling of the plates or leaves.
  • a metal strip or a plate undergoes various operations, such as hot rolling and cold rolling, intended to give it uniform dimensional characteristics over its entire length; thus a laminated metal strip theoretically has a constant thickness and width at all points.
  • the rolling operation is not sufficient to obtain a strip free from defects. Indeed, the latter may have flatness defects such as undulations at the edges or in the center, and a hanger (that is to say a curvature) depending on the length or the width of the strip.
  • leveler consists of two superimposed cassettes each supporting several motorized rollers, offset from one another, and arranged alternately above and below the path of the strip.
  • a reel of metal strip In the case of a reel of metal strip, it is unwound beforehand, generally straightened in a straightener before undergoing the leveling operation.
  • the planed strips In order to deliver products that meet the flatness criteria demanded by manufacturers, the planed strips are not rewound, in fact the winding destroys the flatness. They are therefore cut, at the exit from the leveler, so as to obtain plates, sheets or blanks, either by means of a guillotine shears, or by means of a follower, rotary or flying shears.
  • the plates or planed sheets are then transported to a stacker, and are stacked while awaiting delivery.
  • the leveling proper is carried out by passing the strip or the plate between the offset rollers of the leveler, the clamping of which is adjusted at the inlet, that is to say the spacing of the rollers upstream from the leveler, and at the outlet, that is to say the spacing of the rollers downstream of the leveler.
  • the residual stresses of the strip are homogenized, and thus flatness defects such as undulations and bending according to width are remedied.
  • the bending is processed according to the length of the strip. For the sake of clarity in the rest of the text, when we signify "hanger according to length”, we will simply mention "hanger”.
  • the setting of the clamping parameters at the entry and exit of the leveler is carried out during each change of coil, plate (or sheet), in order to adapt these parameters not only to the dimensional characteristics and to the types of defects of the strip. or plate, but also depending on the hanger, depending on the shape you want to print on the plate (or sheet) after planing.
  • the plates will be delivered with a zero hanger (perfectly flat plate), a hanger positive or a negative hanger.
  • the clamping of the rollers of the entry leveler is first adjusted according to methods known per se, then the clamping of the rollers at the outlet is adjusted.
  • One known means for adjusting the rollers of the leveler at the outlet consists in checking the residual bend of the plate (or of the sheet) after leveling.
  • the plate is lifted by means of a lifter so that the plate is suspended by one or two support points, then an operator measures the hanger of the plate by raising the arrow in the center of the plate using a ruler.
  • the operator can then adjust the tightening setting of the exit rollers to correct the plate hanger and adapt it to the request of the manufacturer. This measurement operation is repeated as many times as necessary during each change of product (in the form of a coil, plate or sheet).
  • the plate lifting operation may involve risks for the operator's safety, in particular for large plates
  • the subject of the invention is therefore a method for regulating in real time a leveler intended for leveling metal strips, plates, or sheets, characterized in that:
  • the measurement of the residual hanger of the planed plate is carried out from a measurement of the curvature of said plate at the outlet of the leveler outside said support zone, said measurement being carried out by means of at least three sensors of distance.
  • the invention also relates to a leveling installation of the type comprising a leveler for leveling metal strips, plates or sheets, characterized in that it comprises means for cutting, after leveling, the strip into planed plates or planed sheets, means for measuring the residual hanger of the planed plates or planed sheets resulting either from the planing of the cut strip, or from the planing of the plate or sheet, at the outlet of the planer, and means for modifying the tightening of the rollers located at the outlet of said leveler according to the indications provided by the measuring means of said residual hanger.
  • the means for measuring the residual hanger comprise at least three distance sensors such as optical distance sensors, or eddy current distance sensors.
  • the leveling installation includes automatic means for adjusting the tightening of the output rollers according to the indications of the distance measurements from the sensors.
  • the measurement of the curvature of the planed plate is carried out at the level of said planed plate outside of a support zone.
  • the invention consists in carrying out a measurement in real time of the hanger of the plate or of the strip cut into a plate at its exit from the leveler, and in controlling the tightening of the rollers according to the results of this measured.
  • FIG. 1 is a schematic cross-sectional view of a leveler
  • - Figure 2 shows the variation in the value of the residual hanger as a function of the tightening of the rollers at the leveler exit.
  • a planer 1 is shown diagrammatically, of two superposed cassettes 2,3 supporting motorized rollers 4, positioned offset from one another, and between which a metal strip 5, a plate or a leaf.
  • the installation comprises cutting means 6 arranged at the outlet of the leveler, a transport table 7, a means of conveying the strip cut into plates (not shown in the figure).
  • the installation comprises cutting means 6 arranged at the leveler exit.
  • the cutting means 6 are superfluous when plates or sheets are planed directly; however, they can be present in the installation and in this case they are not operated.
  • the strip or the metal plate 5 is planed in the leveler 1 by scrolling between the rollers 4.
  • the strip 5 is sheared by the cutting means 6 consisting of either a guillotine shear or a rotary, follower, or flying shear, so as to obtain plates 8, sheets or blanks of a length L determined in advance.
  • the cutting means 6 consisting of either a guillotine shear or a rotary, follower, or flying shear, so as to obtain plates 8, sheets or blanks of a length L determined in advance.
  • a part of the planed plate 8 rests on the transport table 7, while a length of plate L 'determined in advance by a detection cell 10 protrudes from the table 7 and is therefore outside the area of support.
  • the measurements made by the sensors 9 are preferably non-contact distance measurements in order to avoid distorting the measurements of the curvature of the plate part 8 of length L '.
  • Contactless distance sensors 9 will therefore be used such as eddy current sensors or optical sensors ...
  • the hanger of the plate 8 required by the manufacturer can be zero (perfectly flat plate), positive (curvature of the plate up) or negative
  • This operation can also be carried out automatically by a computer.
  • the actuator 12 acts directly on the tightening of the rollers 4a and 4b at the leveler exit 1, that is to say on their relative spacing.
  • the method according to the invention thus makes it possible to control in real time the hanger of each of the plates 8.
  • the real time control of the hanger of the plate 8 allows '' act immediately on the clamping parameters at the exit from the leveler 1 and modify, if necessary, the settings for the clamping at the outlet (rollers 4a and 4b), so as to obtain plates 8 whose hanger is constant, or whose value of the hanger remains within the tolerance limit set by the manufacturer.
  • the method according to the invention eliminates the operations of lifting the plate and measuring the hanger by an operator, and has the following other advantages over the prior art:
  • the device according to the invention is compatible with compact lines, it requires a smaller space than that required by lifting the plate. - systematic control of the hanger of all plates (archiving of values)
  • FIG. 2 shows the variation in the value of the residual hanger (expressed in mm / m) as a function of the tightening of the rollers at the exit from the leveler (expressed in mm).
  • the material considered is a steel strip 6 mm thick, 1500 mm wide and with an elastic limit of 350 Mpa.
  • the initial plasticization rate of the strip is 60%.
  • the maximum plasticization rate targeted for this example is 80%. This imposed plasticization rate depends on the leveling strategy used and on the initial flatness of the strip before leveling. The amplitude of the hanger variations after leveling is directly correlated to this parameter.
  • Example 1 the non-contact distance sensors measure a residual bend of the plate obtained after planing and shearing of the steel strip of + 7mm / m.
  • the regulation system (a) must correct the tightening of the rollers at the exit of the leveler by a correction of 0.15 mm so that the tightening reaches 0.32 mm.
  • Example 2 the contactless distance sensors measure a residual bend of the plate obtained after planing and shearing of the steel strip of -7mm / m.
  • the regulation system (a ') must correct the tightening of the rollers at the exit of the leveler by a correction of 0.2 mm so that the tightening reaches 0.32 mm.
