Definitions

  • the subject of the invention is a method for extending the production range of a cold rolling plant for metal products in strip form and also covers the installations provided with means for implementing the process in order to widen their range of products. production, (see for example JP-A-05 228504 ).
  • the working rolls tend to deviate from one another and the air gap between the generatrices opposite must be maintained by application, between the cylinders, a clamping force often called force or rolling force.
  • the rolling force to be exerted to obtain a certain degree of reduction in thickness depends, in particular, on the diameter of the working rolls which determines the length of the reduction zone as well as the mechanical and metallurgical characteristics, such as its elastic limit, its composition, for example, low-carbon low-carbon steel, stainless steel, alloy steel, etc.
  • the rolling product passes between two working rolls which define the rolling plane; these cylinders are generally of relatively small diameter compared with the forces to which they are subjected; they are supported, respectively, on at least two support cylinders between which is applied the rolling force.
  • the cylinders are supported on each other along substantially parallel bearing lines, and directed along a generatrix whose profile, normally straight, depends on the forces applied and the strength of the cylinders.
  • the clamping force is applied by screws or jacks interposed between the cage and the ends of the shaft of a support cylinder, the other support cylinder bearing by these ends directly on the cage, or by via a wedging device or height adjustment to compensate for variations in diameters of all the cylinders which wear out gradually.
  • the cylinders must therefore be able to move relative to the cage and, for this purpose, are carried by rotary support called chocks, which are slidably mounted vertically inside windows formed in the two columns of the cage, and each provided with two guiding faces of the chock, parallel to the clamping plane.
  • the clamping forces are normally applied between the two ends of the two support cylinders. Since the rolled product, of variable width does not completely cover the length of the working rolls, each roll can bend under the action of the forces applied and the result is a variation in the thickness of the passage space of the roll. band between the working cylinders, which generates defects in profile and flatness.
  • the invention thus provides a production tool easily adaptable to changing needs, both in the quality of the rolled product in the quantities to provide.
  • the invention also covers a rolling plant according to claim 15.
  • the inlet section E comprises devices, not shown, for putting the band in traction, placed just in front of the first cage and a guiding device G.
  • the outlet section S generally comprises a fractional shear C to form coils and, for example, two winders B, B 'each having a device for guiding and deflecting D, D'.
  • such an installation may include a greater or lesser number of cages operating in tandem and, depending on the nature and destination of the product, various processing sections of the metal strip disposed or not in a continuous line.
  • each roll stand is also equipped with devices for controlling the flatness of the product by bending (or bending) the work rolls.
  • each working roll for example the upper roll 2 is associated with two support pieces 40a, 40b mounted sliding axially on the two hydraulic blocks 4a, 4b and on which bear, respectively, the positive bending cylinders 51a. , 51b and the negative bending cylinders 52a, 52b.
  • the two support pieces 40a, 40b are associated with means, not shown, such as hydraulic cylinders, resting on the cage to control the axial displacement of the assembly formed by the working cylinder 2 and its two chocks 20 with the associated support pieces 40a, 40b carrying the sets of bending cylinders 5a, 5b.
  • each projecting piece 13 also carries two sets of cylinders, respectively upper 50 and lower 50 'provided for the bending of the working rolls in the sexto configuration shown in FIG. figure 4 .
  • the last cage L4 is also transformable in order to configure it in sexto mode for the manufacture of steels with a very high elastic limit and particularly those of the "TRIP" type.
  • the figure 5 shows, in elevation, the central part of such a transformable cage, sexto configuration.
  • the cage thus comprises six cylinders superimposed on both sides of the rolling plane P, respectively two work rolls 22, 22 ', two intermediate rolls 32, 32' and two support rollers 3, 3 '.
  • the two cylinders 61, 62 of each cassette 6 are rotatably mounted, at their ends, on two frames 7 having a shape similar to that of the chocks 23 of the working cylinders 22 of the sexto configuration and therefore comprising parts of 71, 72 spaced vertically the same distance as the support portions 24, 25 of a work chock 23 and thus passing, respectively, above and below the projecting parts 42a, 42b whose ends 43 form vertical guide faces of the frame 7 in the form of a chock.
  • each cassette 6 of an octo configuration has the same profile as the chocks 23 of the working cylinder 22 of the sexto configuration, it is possible to use a system for rapid replacement by displacement parallel to the axes of the cylinders. chocks 23 or chassis 7 supported, by means of rollers 26, 73, on rails 46 formed on the projecting parts 42a, 42b.
  • the projecting parts 42, 42 'carry sets of bending cylinders which remain in place during the configuration change and act, in the positive or negative direction, either on the working cylinders 22, 22' in the sexto configuration, or on the second intermediate cylinders 62, 62 ', in the octo configuration.
  • Each second intermediate cylinder 62 is provided at each end with a journal carried by a bearing 74 whose outer cage is fixed on the chassis 7, which thus acts as a chock for the cylinder 62.
  • the associated working cylinder 61 is simply rotatably mounted at each end on an axial abutment bearing 75 but this latter is mounted, with a possibility of transverse play, in a retaining member 76 fixed on the internal face of the frame 7 and comprising a spring device 77 which permanently applies the working cylinder 61 to the intermediate cylinder 62, so as to take into account a variation, by wear, of the diameters of the rolls, as shown in FIG. figure 11 .
  • working rolls of such small diameter may bend during rolling and therefore should preferably be associated with side support rollers in an X arrangement, shown by way of example on the figure 6 .
  • each set of rollers 8 can be easily disassembled with its support frame 81, so as to clear the central space of the cage in the sexto configuration shown in FIG. figure 5 , the four slides 82 and the cylinders 83 remaining alone fixed on the columns 10 of the cage.
