Definitions

  • Rolling metal products in the form of tape is normally carried out in a train of rolling mills each consisting of a cage comprising two support columns spread apart and connected by sleepers, between which is mounted a set of superimposed cylinders having parallel axes and placed substantially in the same clamping plane substantially perpendicular to the direction of displacement of the product.
  • each cylinder is mounted rotatable, around its axis, on bearings carried by two support members called chocks and this one are slidably mounted, parallel to the plane of clamping passing through the axes of the working cylinders, each between two flat guide faces provided respectively on either side of said plane of clamping on both sides of the window corresponding from the cage.
  • each support block usually has three projecting parts, respectively a central part placed at the level of rolling plan, in which the cylinders are housed of positive bending of the two chocks and two parts support placed, respectively, above and in below the rolling plane and in which are housed the negative camber cylinders of both cylinders, respectively upper and lower.
  • the invention therefore applies, in a way general, to a known type rolling mill comprising two sets of cylinders placed on either side of the plane clamping and acting respectively on two choke support ears of each cylinder of work, respectively higher or lower, each set of camber cylinders comprising at least two positive camber cylinders supported, respectively, on the inner faces of the ears two chocks and at least two camber cylinders negative bearing respectively on the face outer ears of the two chocks, the cylinders of negative arching of a first chock and the jacks of the camber of the second chock having fixed elements mounted on the same side of the rolling plane and mobile elements supported, respectively, on the external face of the support ear of the first chock and on the inner side of the ear support of the second chock, the mobile elements second camber positive camber cylinders crossing the rolling plane.
  • the invention also makes it possible to facilitate the installation of the cambering system in the cage.
  • the ear support parts of a first chock and the free spaces of the ears of the second chock are centered in a first diagonal plane passing through the central axis of symmetry and in which are centered, respectively, two camber cylinders positive and two negative camber cylinders of the first chock and ear support parts of the second chock and the free spaces of ears of the first chock are centered on a second diagonal plane passing through the central axis of symmetry and in which two cylinders are centered positive camber and two negative camber cylinders the second chock.
  • each a first working cylinder is provided, on a first side of the clamping plane, first ear with a single centered support part on a median plane of the sponge passing through the axis center of symmetry and on which are supported, opposite directions, a positive camber cylinder and a negative camber cylinder of the first cylinder, said cylinder single support part framed by two spaces free passage of the moving parts of two cylinders positive bending of the second working cylinder and, on the second side of the clamping plane, one second ear in which a free space is provided central passage of the movable element of a cylinder positive camber of the second working cylinder, centered on the median plane of the chock, said free space central being framed by two support parts, respectively, of two positive camber cylinders and two negative camber cylinders of the first cylinder of work.
  • Figure 1 there is shown in section transverse, the classic layout of a rolling mill quarto type including, inside a cage having two spaced apart columns 1, two cylinders of work, respectively upper 2 and lower 2 ', which are supported, respectively, on two cylinders support, upper 21 and lower 21 'and define an air gap for the passage of an M band to be laminated, moving along a rolling plane P1.
  • the chocks 4, 4 ′ of the cylinders of work 2, 2 'of smaller diameter are less wide that the chocks 41, 41 ′ of the support cylinders 21, 21 'and their guide faces must therefore be less set aside.
  • the guide faces 12a, 12b of the chocks are arranged on the faces opposite two machined blocks 3a, 3b which are mounted respectively on the two uprights la, 1b of the column and extend inwardly projecting from window 10.
  • Level of upper support cylinder 2 is adjusted by clamping means not shown, such as screws or cylinders, which are mounted at the upper part of the two columns 1 of the cage for build on chocks 41 and which allow, in addition, to apply the necessary rolling force thickness reduction.
  • these cylinders act on support parts provided on either side of each chocks and which form opposite ears 7, 7 ' each projecting from the side corresponding side 42 of the chock.
  • the two chocks 4, 4 in the tightened position of the working cylinders shown in the half view of left and for which the used cylinders have the smaller diameter, the two chocks 4, 4 'come practically in contact with each other.
  • the dimensioning of the different parts of the blocks support 3 and working chocks must therefore hold account of the wear range, especially when you want to keep the rolling plan at a constant level.
  • the underside 43 of the chock 4 is located below the rolling plane in the maximum wear position.
  • each cylinder of positive camber 5 must be placed next to the body 61 ' of the 6 'negative camber cylinder, in the lower projection 32 ′, and the rod 52 of the jack 5 must cross the ear 7 'of the lower chock 4' to pass to the other side of the rolling plane P1 and lean on the internal face 71 of the ear 7 of the top working chock 4.
  • Each 7 'ear of the chock therefore has a stepped profile comprising a part 73 ′ for supporting the cambering cylinder negative 6 'which covers only part of the length of the chock, in the longitudinal direction of the axis of the cylinder, so as to leave a free space 74 'allowing passage of the cylinder rod 5 of positive camber.
  • Figure 4 which shows schematically, in perspective, the set of two chocks 4, 4 ', we sees that the layout is reversed for the chock upper work 4 and the cylinders placed in the upper holding parts 32a, 32b of the blocks support 3a, 3b; the 5'a positive camber cylinders, 5'b of the lower cylinder 2 'are centered in the second diagonal plane Q2 while the cylinders of negative camber 6a, 6b of the working cylinder upper 2 are centered in the first diagonal plane Q1.
  • the support ears 7a, 7b of the upper working chock 7 shown in phantom in FIG. 7 are arranged in an inverse manner and therefore comprise, on the left, two parts 73a 1 , 73a 2 , for supporting the two jacks positive camber 5a 1 , 5a 2 and, on the right, a support part 73b framed by two free spaces 73b 1 , 73b 2 for passage of the rods of the jacks 5'b 1 , 5'b 2 of positive camber of the lower cylinder 2 '.
  • each holding part respectively upper 32 or lower 32 ', from a support block 3 is determined according to the stroke of the cylinder positive camber which itself depends on the length that we have to give to the cylinder rod to make it lean on the ear of the chock placed from the other side of the rolling plane P1, the cylinders of negative camber with a lower stroke.
  • the internal faces 71a, 71b of the two ears 7a, 7b are then placed substantially at the level of the internal face 43 of chock 4 facing the rolling plane. This is itself spaced from the cylinder axis by a distance a little less than the smallest radius of the working cylinder 2. In this way, when the cylinders are in their maximum state of wear, the internal faces 71, 71 'of the ears 7, 7' of the two chocks 4, 4 'being almost in contact with one of the other, in the rolling plane P1, taking into account the necessary adjustments for negative bending.
  • the number of guide faces fixed and lateral chock holding faces is decreased.
  • the surfaces of slip must be fitted with attachments made of a material with a coefficient of friction suitable for use and which constitute parts of wear.
  • the decrease in their number through the adoption of all the arrangements according to the invention, reduces the cost of installation as well as production costs by simplifying operations maintenance and by reducing the necessary duration of interventions.
