Definitions

  • the subject of the invention is a device for guiding a strip product intended especially for production and processing installations for hot-rolled or cold-rolled metal strips.
  • the steel and metallurgical industry makes available to users and processors various types of products having various sizes and, in particular, flat products consisting of sheets of varying thickness depending on use, and which are generally wound in coils.
  • each treatment therefore requires a specific installation and a scrolling speed adapted to the treatment. Therefore, previously, the various treatments were normally performed in separate sections each associated with a unwinder and a winder placed, respectively, upstream and downstream in the direction of travel. In this case, the web runs to pass into the processing section and is wound at the exit thereof forming a reel which is transported to the next processing facility.
  • the weight of the coil obviously depends on the thickness of the sheet and the rolled length, as well as the nature of the metal but it is still very important.
  • the weight of a coil is commonly 15 to 25 tons. It is therefore necessary to lifting and handling equipment adapted to the dimensions and weight of the reels for transporting them from one processing section to the next.
  • the strip may form, between two successive treatment sections, a free loop suspended between two deflection rolls whose axes can be oriented differently to change the direction of scrolling.
  • a free loop is subjected only to its own weight and it is therefore necessary to provide, upstream and downstream, tensioning devices for reducing the tensile force on the strip to the value necessary in the other sections. This increases the size of the installation and complicates the control of the scrolling of the band.
  • the angular deflection is relatively low, for example 20 ° and that the distance between two consecutive rollers is of the order five times the width of the strip. Therefore, to make a deflection, for example, of 90 °, it is necessary to multiply the number of rolls.
  • the difference in level between two consecutive rolls must be in the order of 7 to 10 meters for a bandwidth of between 1.5 and 2 meters.
  • the band normally arrives near the small base of the conical roller and progressively moves away towards the large base during its rotation.
  • the orientation of the strip with respect to the successive generatrices of the cone on which it is based varies progressively as well as the tangential speed and it is therefore necessary, in order to avoid deterioration of the strip, to apply it to a set of rollers rotatably mounted about axes perpendicular to the direction of travel and which are divided into series each defining a bearing generatrix of a virtual conical surface enveloping all the rollers.
  • the support rollers of the strip are mounted on a fixed support. Their orientation and their spacing must therefore vary from one series to another to follow the progress of the tape. However, because of the conicity of the bearing surface, the band tends to slide towards the large base and must therefore be maintained laterally.
  • the use of two baffles placed upside down, as described in the document JP-A-59-229230 allows, however, to avoid this disadvantage.
  • the object of the invention is to solve all of these problems by means of a device that is simpler and less expensive than the known devices and also makes it possible to maintain the orientation of the strip with respect to its support members by thus reducing the risk of slipping and deterioration of its surface.
  • such a device provides many possibilities of deflection and change of direction to adapt simply and inexpensively to an existing or new plant, using shorter hall lengths and a number of lifting bridges less important than in a conventional installation.
  • the invention therefore relates to a device for guiding a strip product moving along a longitudinal axis and comprising at least two conical deflectors each having a right end and a wide end and arranged head to tail, the narrow end of one deflectors being placed on the same side, with respect to the axis of the strip as the wide end of the other deflector.
  • each deflector comprises each deflector comprises a fixed support on which are mounted, in the manner of satellites, a plurality of rollers of guiding distributed over an angular deflector deflector sector and rotatably mounted about axes forming the same angle (A) with an axis of the deflector and, the strip being applied under tension on each deflector, along a passing virtual conical surface by an external generatrix of each roller, the axes of the deflectors are oriented relative to the longitudinal axis of travel of the strip so that it comprises successively, in the direction of travel, an upstream portion tangent to a generator of input to a first deflector and having an axis perpendicular to said input generator, a central portion tangent, upstream to an output generator of the first deflector and, downstream, to an input generator on the second deflector and having a longitudinal axis perpendicular to said generatrices, respectively output and input, and a downstream portion tangent to a
  • the strip can be subjected to a tensile stress determined according to the rigidity of the strip so as to produce an application under tension with elastic deformation of the strip on the set of rollers of each of the deflectors, the head-to-tail assembly of said deflectors compensating for differences in elongation on both sides of the strip, on either side of the longitudinal axis and determining a centering effect of the strip with a progressive rotation of its longitudinal axis capable of maintaining the perpendicularity of the latter with the external generatrix of each of the rollers of the deflector.
  • the tensile force applied to the strip is distributed over the width of the latter gradually increasing from its inner edge located on the narrow side of the deflector to the outer side of the bank on the broad side, with a gradual elongation of the fibers of the web, so that the tangential velocity of each fiber along a external generator of each satellite roller is substantially constant from one bank to another.
  • each roll of a deflector has a curved outer profile, with a central portion of diameter slightly greater than the ends, and the tensile force applied to the strip determines a self-centering of the strip of which the longitudinal axis remains in the central portion and orthogonal to the external generatrix of each of the rollers of the deflector.
  • the device comprises an even number of baffles associated two by two, the two baffles of each pair having the same angle (A) of inclination of the guide rollers.
  • the axes of two successive deflectors are oriented so that the output generator of the first deflector and the input generator on the second deflector are parallel and placed in the same tangent plane common to the two deflectors, in which extends the central portion of the strip.
  • the output generator of the first deflector and the input generator on the second deflector are placed in two planes parallel to each other and perpendicular to the axis of the central portion of the strip and are between they have a non-zero angle, said generatrices being spaced apart by a sufficient distance so that the longitudinal median plane of the central part rotates progressively about the axis.
  • the two baffles are placed on the same side of the strip and thus perform an inversion of the direction of travel.
  • the invention makes it possible to vary, on the one hand, the angle at the apex of the baffles, and on the other hand, their relative positions and their orientations to determine a lateral offset or an angular deviation of the band.
  • A being the angle at the apex of each deflector and H the distance between the two scroll planes respectively upstream and downstream of the strip.
  • the axes of the two deflectors are oriented so that the input generators on the first deflector and output of the second deflector are between them a non-zero angle, the upstream part and the downstream part of the band. being centered, respectively, on two longitudinal median planes forming between them the same non-zero angle.
  • the figure 1 shows, in perspective, a satellite roller deflector according to the invention.
  • the figure 2 is a front view of a device with two baffles according to the invention.
  • the figure 3 is a perspective view of the device of the figure 2 .
  • the figure 4 shows, in front view, a lateral offset device with four deflectors.
  • the figure 5 is a schematic view from above of the device of the figure 4 .
  • the figure 6 shows, in perspective, an angular deflection device.
  • the figure 7 shows an angular deflection device of two substantially horizontal strands.
  • the figure 8 is a side view of the device of the figure 7 .
  • the figure 9 is a top view of the entire device of the figure 7 .
  • the baffle roller modifies the direction of the plane of travel of the two parts, respectively upstream and downstream of the strip tangential to the baffle rollers, but these remain centered in the same longitudinal median plane orthogonal to the axis of rotation of the roll. cylindrical.
  • the object of the invention is a new type of conical deflector constituted, as shown in FIG. figure 1 , a fixed support 3 carrying a plurality of cylindrical rollers 4 distributed on its periphery in the manner of satellites.
  • Each satellite roll 4 is rotatably mounted about an axis 40 on two bearings 41, 41 'housed in housings fixed respectively on two ends, respectively enlarged 31 and thinned 31' of the support 3 which, in the example shown is limited by a conical face 33 of revolution about an axis 30, having an angle at the apex A.
  • the support 3 carries rollers 4 only on an angular sector 32 of winding of the band 1. Therefore, the conical face 33 of the support rollers 4 could be limited to this angular sector 32 which, most often will cover substantially a quadrant.
  • the axes of the rollers 4 are parallel to this conical face 33 and are therefore themselves placed in a virtual conical surface centered on the same axis 30 and having the same angle at the apex A.
  • the band 1 rotates around the deflector 2 following a virtual conical surface 43, symbolized in dashed line on the figure 6 , which passes through the generatrices of support 5 by wrapping all the rollers 4.
  • the strip comes into contact with the deflector 2 only along the external generatrices 5 of the rollers 4 which rotate about their axis 40.
  • the strip to be guided is normally a metal strip which, given its rigidity, must be subjected to a large tensile force to apply on the baffle roll.
  • the axis 30 of the deflector is oriented with respect to the general running direction of the strip so that the axis 10a of the upstream portion 1a thereof is perpendicular to the external generator. 5a of the first roller 4a and that the axis 10b of the downstream portion 1b is perpendicular to the external generator 5b of the last roller 4b of the series.
  • the strip is made of an elastoplastic material such as a metal and is kept under tension, it can be progressively deflected while remaining orthogonal to each roll and elastically deforming between two successive rolls, the elongation rate of the fibers longitudinally of the strip gradually increasing from its inner edge 12 facing the narrower end 31 'of the support 3 to the outer edge 13 facing the enlarged end 31.
  • this variation in the elongation rates of the longitudinal fibers of the strip is compensated in a guiding device according to the invention which comprises two baffles 2, 2 'having the same angle at the apex A and placed head to tail, of the as shown in the other figures, the narrow end of one of the deflectors 2 being placed on the same side as the wide end of the other deflector 2 'relative to the longitudinal axis of travel of the strip.
  • each roller 4 is not rigorously cylindrical but may be slightly curved, the diameter of its central portion 44 being a little larger than that of the ends. 42.
  • the figure 2 shows, in front view, such a guiding device shown in perspective on the figure 3 and comprising two deflector members 2, 2 'mounted on a frame C at two different levels.
  • Each deflector 2, 2 ' is of the type shown in the figure 1 and therefore comprises a support 3 centered on an axis 30 and on which are mounted a plurality of satellite rollers 4 each rotating about an axis making, with the axis 30 of the support, an angle A which constitutes the angle at the apex of the conical deflector.
  • the two baffles 2, 2 ' have parallel axes and inclined at the same angle A with respect to the horizontal. In this way, as we see on the figure 3 , the band 1 which arrives at a lower level in a running direction F successively passes on the two deflectors 2, 2 'and leaves in the opposite direction F', at a higher level.
  • the axis 30 of the lower baffle 2 is parallel to the plane of the figure and inclined relative to the horizontal of the angle at the apex A.
  • the part 1a of the band arriving upstream of the lower baffle 2 is centered on a horizontal axis perpendicular to the plane of the figure and the lower generatrix 5a of the deflector 2 which constitutes the input generator on it.
  • the band wraps around the lower deflector 2 by elastically deforming, and its central portion 1b between the two deflectors 2, 2 'is centered on an axis 10b perpendicular to the output generator 5b which is placed in an inclined plane of the angle A with respect to the horizontal.
  • the longitudinal axis 10b of the central portion 1b is therefore inclined at the same angle A with respect to the vertical and perpendicular to the inlet generator 5'a on the second deflector 2 ', which is itself placed in an inclined plane the same angle A with respect to the horizontal.
  • the band 2 then winds on a quadrant of the upper deflector 2 'and its downstream part 1c leaves the device in a horizontal direction F' perpendicular to the plane of the figure 2 and the output generator 5'b of the upper baffle 2 '.
  • the output generator 5b of the first deflector 2 and the input generator 5'a on the second deflector 2 ' are not parallel.
  • the central portion 1b of the strip is thus subjected to a slight twist which does not, however, have any disadvantage if the height H is large relative to the width of the strip.
  • the longitudinal axis 10b being perpendicular to the two generatrices, respectively 5b output and input 5'a, the two banks 12b, 13b of the central portion 1b of the strip have the same length and mounting head- spade of the two deflectors 2, 2 'makes it possible to compensate for the differences in elongation along each conical deflector, so that the paths followed by the different longitudinal fibers of the strip have the same length.
  • deflector members having a conical winding surface provides multiple possibilities of arrangement of said conical deflectors whose number and orientations can be varied in order to optimally respond to the installation requirements of the different sections of an installation, in particular for the modernization of an existing installation.
  • Figures 4 and 5 show another arrangement for making a large transverse shift on two parallel strands of the strip moving in the same direction.

  • the band 1, which is wound successively on each of the four deflectors 25, 2, 2 ', 25' comprises an inlet strand 15a which arrives in the direction of movement F and is tangential to a horizontal inlet generator 45a of the first conical baffle 25, a descending oblique strand 15b, a horizontal strand 15c, an upward oblique strand 15d and an output strand 15e tangential and perpendicular to an output generator 45'b of the last deflector 25 '.
  • odd input generators 5a and 5'a respectively on the first 25 and the third deflector 2 'and the even output generatrices, respectively 5b of the second deflector 2 and 45'b of the fourth deflector 25', are all horizontal and parallel to each other so that the incoming strand 15a and the outgoing strand 15e scroll horizontally and in the same direction along parallel directions F, F '.
  • the oblique strands 15b, 15d are slightly twisted, but this torsion effect is not disadvantageous if the difference in level H between the input and output generators of each pair of deflectors, respectively 25, 2 and 2. ', 25' is large relative to the width of the strip 1.
  • this arrangement thus makes it possible to double the misalignment without modifying the direction of travel of the strip.
  • rollers 25, 25 are not necessarily at the same level and that one can adjust their positions relative to the two lower rollers 2, 2 'so as to achieve the desired misalignment.
  • the two successive deflectors of 2, 2 ' can be arranged so that the generatrix 5b output of the first deflector 2 and the generator 5'a input on the second deflector 2' are parallel and placed in the same plane of scrolling of the central part 1b of the band.
  • the input generatrix 5a on the first deflector 2 and the output generator 5'b of the second deflector 2 ' are still placed in two parallel planes but make an angle between them 2A', A 'being the projection of the angle at the apex A on a horizontal plane.
  • the directions F and F 'of the upstream portion 1a and the downstream portion 1c are between them the same angle 2A'.
  • the height offset of the two parts, respectively upstream 1a and downstream 1c of the band can be reduced in the case where the central portion 1b remains flat.
  • a deflection angle of about 45 ° can be achieved.
  • both deflectors can be placed so that the intermediate strand is horizontal.
  • the axes of the supports 3, 3' can be oriented so as to increase the deflection angle between the input and output generators and, therefore, between the axes 10a, 10c of the strands entering 1a and outgoing 1c.
  • the angular sector 32 of application of the strip on a deflector is not necessarily straight and the input 1a and output 1c strands may not be horizontal but form, on the contrary, an upward or downward ramp.
  • the invention therefore provides multiple possibilities of arrangement of the successive sections of a treatment plant, in particular for the realization of a continuous line in an existing plant.
