Definitions

  • Westin ABSTRACT Disclosed are two embodiments of apparatuses for performing work on metallic slabs to substantially reduce their width.
  • a pair of driven slab reducing rolls each rotatably supported in a housing. The rolls are adjustably positioned relative to each other to reduce the slabs to a desired width.
  • Concentrically carried on each roll are a pair of spaced anvil collars, one of which is adjustably positionable relative to the other to accommodate slabs of different thicknesses.
  • a pair of adjustably positionable slab squeezer heads one of which is reciprocated relative to the other. Pairs of platens adjustably support and locate the slab in a direction normal to the movement of the reciprocating squeezer head.
  • the present invention relates to an apparatus for making large or substantial reductions in the width of metallic slabs to provide slabs having predetermined widths for further 1 processing by rolling mills to produce billets, plates, strip, and
  • the invention is particularly useful in combination with a continuous casting machine.
  • a continuous casting machine may be employed to produce from molten metal a casting of certain cross-sectional dimensions and an undetermined length which is immediately cut into slabs of a desired length.
  • the slab at this point, may be subject to a conventional rolling operation well known in the art per se for any one of a number of purposes.
  • the slabs are then transferred to some other location where they are prepared for further processing in a rolling mill to produce plate, strip and like products. It is important to note that the width of a cast slab is a function of the continuous casting mold size and, therefore, it is necessary to employ a particular size mold to yield a desired slab width.
  • a set of molds is made available to produce the various slab widths consistent with a desired dimension of the slab to be further processed in the rolling mills.
  • constraining means engaging opposed sides of the workpiece adjacent to and in a direction normal to the workpiece engaging means, the constraining means being constructed and arranged to minimize local increases in workpiece thickness during reduction of the widths of the workpiece;
  • FIG. 1 is a plan view of a continuous casting installation incorporating the features of one embodiment of the present invention
  • FIG. 2 is a plan view of one of the slab edge rolling machines illustrated in FIG. 1 incorporating the features of the present invention
  • FIG. 3 is a sectional view taken along lines III-III of FIG. 2;
  • FIG. 4 is a sectional elevational view of a slab squeezing machine which represents 'a second embodiment of the present invention
  • FIG. 5 is a sectional view taken along lines V-V of FIG. 4.
  • FIG. 1 illustrates a continuous casting line 10 which includes a continuous casting machine 11 constructed in a manner well-known in the art.
  • a continuous casting machine 11 constructed in a manner well-known in the art.
  • One suitable form of such a machine is disclosed in U.S. Pat. No. 3,370,641, issued to the assignee of the present invention
  • the casting machine and, particularly, the open-ended, fluid-cooled mold forming a part thereof will be constructed to produce a solidified casting having predetermined cross-sectional dimensions, for example, 74 inches wide and 12 inches thick.
  • Such a casting is generally indicated by the numeral 12, the cross section of which is indicated by the numeral 12a, at a point along conveyor table 13 subsequent to being divided into the desired length by the shear 14.
  • slab width reducing machines 15 and 16 are also incroporated in the conveyor table.
  • slab width reducing machines 15 and 16 each constructed according to the preferred embodiment of the present invention and employed to materially reduce the width of the cast slabs a predetermined amount such as is shown at 17 and in cross section at 170. While two slab width reducing machines are illustrated three or more machines may be arranged in tandem to reduce the width of the slabs to such an extent whereby further processing in a rolling mill will yield finished or semifinished strip, plate, or the like having the desired width.
  • the slab reducing machines are each identically constructed and include a housing frame made up of spaced-apart parallel posts 18 and 19 horizontally supported by a foundation.
  • Crossheads 21 and 22 interconnect the posts at their ends and serve to adjustably position roller assemblies 23 and 24, respectively, relative to each other.
  • Each of the crossheads as shown in FIG. 3, includes a screw 25 having a threaded portion 25a received in a nut 26 that is secured against rotation in the crosshead.
  • the screw 25 is caused to rotate by a worm wheel 27 in mesh with a worm 28 that is, in turn, connected to a motor, not shown.
  • a bearing chock 31 engaged by one end of the screw 25 and slidably supported between the posts 18 and 19.
  • An arbor 32 is rotatably carried by the chock 31 and has a downwardly extending end to which there is connected a universal spindle 33.
  • a drive 34 having bevel gears 35 and 36 transmits torque from the motor 37 to the spindle 33 and, hence, to the roller assembly 24.
  • a composite roller having two essential elements 38 and 39, each having threads 40 to permit adjustment of the latter relative to the former.
  • the element 38 is formed with a slab edge engaging portion 41 and a slab constraining collar 42 which includes a hardened insert 420.
  • the element 39 has a slab constraining collar 43 provided with a hardened insert 43a.
  • Two pinion gears 44 in mesh with gear teeth formed on the element 38 are rotatably mounted in the element 39v
  • the motors 47 are supported by the element 39 and connected to a source of power through electrical collectors 48.
  • operation of the motors 47 causes relative rotation between the elements 38 and 39 of the roller assemblies 23 and 24, thereby adjustably varying the distance separating the hardened inserts 42a and 43a to accommodate slabs of different thicknesses therebetween.
  • the screws 25 are rotated sufficiently to preposition the roller assemblies 23 and 24 relative to each other whereby, when slabs are passed therebetween, the desired final width may be obtained.
  • FIGS. 4 and 5 there is illustrated a second embodiment of the present invention in the form of a slab squeezer 51 to be incorporated in the roller table 13 (FIG. 1) in place of the slab reducing machines 15 and 16.
  • FIG. 4 supported at the sides of the table are stationary crossheads 52 and 53 that are secured together by upper and lower tension bars 54 and 55.
  • a horizontally movable bolster 56 is slidably supported by the bars 55 and arranged between the roller table and the crosshead 52.
  • a piston cylinder assembly 57 is supported by the crosshead and arranged to engage the bolster 56 for reciprocating it with a force sufficient to effect substantial reductions in the slab 59.
  • Rigidly secured to both the bolster 56 and the crosshead 53 are nuts 61. Received in each nut is a screw 62 adapted to be rotated by a worm wheel and worm assembly 63 for the purpose of positioning squeezer heads 64 and 65 relative to each other for accommodating slabs of different widths.
  • squeezer heads 64 and 65 having wear plates 64a and 65a, respectively, secured thereto, extend the full length of the slab to be worked upon.
  • a support frame 66 incorporated in the roller table 10 slidably positions the squeezer heads vertically for engaging a slab at a desired elevation.
  • slab elevating devices Essential to the successful operation of the slab squeezer is the use of slab elevating devices, next to be explained, the function of which is to lift and hold a slab above the conveyor 10 at a predetermined elevation, such that the application of the slab squeezing force will be applied symmetrically to the slab at an elevation coinciding with the centerline of the piston cylinder assembly 57. In this manner, large reductions in the width of the slab can be accomplished without local bulging.
  • elongated aprons 71 are arranged between and extend in a direction parallel to the rollers 10a of the conveyor 10.
  • aprons 72 are space directly above the aprons 71.
  • Aprons 71 are employed to raise the slab to the aforementioned predetermined elevation whereupon the aprons 72 are lowered into engagement with the top surface of the slab to rigidly constrain it during the squeezing operation and thereby materially eliminate any tendency to produce local bulging of the slab.
  • Each of the aprons 71 and 72 is connected to a bell crank 73 and 74, respectively, which, in turn, are pivotally supported by the tension bars 54 and 55 and interconnected by connecting rods 75 and 76.
  • a piston cylinder assembly 77 is operatively secured by its rod end to the bellcrank 73 to raise the aprons 71 in unison and a piston cylinder assembly 78, connected by the rod end thereof also to the bellcrank 73, is operated to lower the aprons after the squeezing operation.
  • the aprons 72 are lowered and raised in unison by a piston cylinder assembly 79 operatively connected by the rod end thereof to one of the bellcranks 74.
  • slabs comprising:
  • a pair of constraining means including metal reducing surfaces for engaging with the opposed sides of said workpiece in a plane normal to said plane of the workpiece for reducing local increases in workpiece thickness simultaneously with the reduction in width thereof;
  • said adjustment means comprises:
  • a roller having a work surface constructed and arranged to contact an edge of the workpiece
  • a chock rotatably supporting said arbor, said drive means coupled to said arbor for transmitting torque to said roller.
  • tension rods interconnecting said crossheads for resisting the force generated between said squeezer heads incident to reducing the thickness of a workpiece.
  • positioning means connected to said first and second plurality of platens for constraining a workpiece at said desired elevation.
