Definitions

  • ABSTRACT A slab conditioning system including a pair of rotatable leaves for supporting metal slabs and a conditioning tool platform mounted above the leaves and adapted to traverse the slab during the conditioning process.
  • This invention relates to the conditioning of metal slabs; more particularly to a system for conditioning the surfaces of metal slabs and method of operation therefor.
  • Typical of the problems associated with surface conditioning of metals are those presented in the manufacture of steel.
  • the primary technique for removing surface defects in semi-finished steel slabs, billets and blooms is by scarfmg.
  • Scarfmg consists of the application of oxygen and gas to the steel surface, usually by a torch, to oxidize the steel and thereby generate elevated temperatures that cause the oxidized product and adjacent steel to become liquid, which is then blown away.
  • surface conditioning of steel is also carried out by grinding, particularly on stainless steel, and by hand chipping.
  • scarfing has been a manual operation performed in a mill yard by a workman standing on a steel slab and manipulating a scarfing torch. This means, of course, that the slab must be cooled sufficiently to permit the workman to walk upon it. When one surface is completed, the slab is lifted with a chain or magnet held by an overhead crane and by some means turned over and lowered on the scarfed side; the manual scarfing process is then repeated. Slab weights have recently reached up to 40 tons or more and have thus made this turnover operation dangerous to workmen nearby. Moreover, scarfing produces heat and noxious fumes, thereby presenting health hazards to the workmen involved in the scarfing operation. Also the arduous nature of the operation rapidly fatigues the worker and reduces his productivity.
  • automatic scarfing units have been installed in some plants in an in-line relationship with rolling mills.
  • Automatic scarfing units consist of a number of scarfing torches so designed that theyform a pass on the mill; accordingly, steel may be scarfed in the hot condition.
  • scarfing is virtually indiscriminate with automatic scarfing machines and may result in reductions in metal yield up to 3-4 percent, depending on the size of slab or bloom and the depth of scarfing.
  • the present invention overcomes the disadvantages and objections associated with present metal surface conditioning equipment and methods. Not only are more efficient operating procedures afforded with the present invention, but also personnel safety hazards are markedly reduced.
  • the present invention provides a slab conditioning system comprising: a base, a pair of independently rotatable leaves each adapted to support a slab, each of the leaves being pivotally mounted to the base to rotate in a direction toward the other for transferring the slab from one of the leaves to the other; means for independently rotating the leaves; and a slab conditioning tool platform rotatably mounted above the leaves and adapted for translatory motion with respect to the leaves.
  • the translatory motion of the tool platform includes longitudinal, lateral and vertical motion with respect to a line parallel with and central of the pivotal axes of the leaves.
  • each of the leaves is rotatable from a horizontal position through more than 90 in a direction toward the other leaf and that the leaves each include a frame and slab stop means extending perpendicularly from the portion of the frame adjacent to its pivotal mounting to the base.
  • the slab stop means of each of the leavesv are preferably positioned to cooperate with the other in the transfer of the slab.
  • the means for rotating the leaves comprises lift cylinders operably connected between the base and each of the leaves.
  • the slab conditioning tool platform of the present invention preferably depends from an overhead support means positioned in a vertical plane central of the pivotal axes of the leaves.
  • the platform is adapted for at least 270 of rotation.
  • the present invention further provides, in a slab conditioning system, the improvement comprising: a base; a pair of independently rotatable leaves each adapted to support a slab, each of the leaves being pivotally mounted to the base to rotate in a direction toward the other for transferring the slab from one of the leaves to the other; and means for independently rotating the leaves.
  • liquid spray means are mounted on the leaves and adapted to discharge the spray simultaneously against the top and bottom surfaces of the slab being supported in an upright position by the leaves.
  • the present invention further provides a method for conditioning metal slabs comprising: (A) delivering a slab to a first rotatable slab support means from a first direction; (B) rotating the first slab support means to incline the top surface'of the slab; (C) longitudinally traversing the top surface with a conditioning tool to selectively condition the top surface; (D) transferring the slab from the first slab support means to a second rotatable slab means; (E) rotating the second slab support means to incline the bottom surface of the slab;

  • FIGS. 1 and 2 there is shown an I- shaped pit 10 formed in the floor 12 of a mill area.
  • Pit 10 is encased in concrete and has a concrete floor 14.
  • a rectangular concrete bridge 16 having a top surface level with mill floor 12 spans pit 10 across the midpoint of the neck of the I.”
  • An elongated rectangular base 18 is supported on bridge 16 and the portions of the mill floor 12 extending on either side of bridge 16.
  • Base 18 is formed of heavy gauge stock and includes a pair of central I-I-beams 20 extending longitudinally of base 18. The side edges of base 18 overhang bridge 16.
  • the open portions of pit 10 on each side of bridge 16 are enclosed by removable floor plates 22 extending from the mill floor 12 to the overhanging side edges of base 18.
  • a slab handling unit is mounted on base 18.
  • Slab handling unit 23 includes a pair of rotatable leaves. For convenience herein, these leaves will be referred to as leaf 1 and leaf 2 and are so designated on the drawings. Since leaf 1 and leaf 2 are of identicalconstruction (except for certain differences which will be noted), only leaf 1 will be described.
  • Leaf 1 includes a frame 24 having a pair of spaced longitudinal frame members 26 and 28 formed from heavy gauge I-beams. Frame members 26'and 28 are connected by transverse frame separators 30, 32, 34 and 36, also of I-beam configuration. Frame 24 sup ports top plates 37. Mounted on top plates 37, longitudinally above frame separators 30, 32, 34 and 36, respectively, are wear plates 38, '40, 42 and 44. Wear plates 38, 40, 42 and 44 are designed to support a slab resting on leaf 1.
  • slab stops 46, 48, 50 and 52 are aligned slab stops 46, 48, 50 and 52.
  • Slab stops 46, 48, 50 and 52 are formed of heavy gauge stock having uneven sides;
  • each stop has a pair of spaced, transverse stiffeners joining the sides of the stop, the long side of which forms the face 54 of each stop.
  • the slab stops of leaf 2 are also mounted in offset fashion but on opposite sides of the centerline of their associated frame separators from the slab stops on leaf 1. This oppositely offset mounting of the slab stops permits them to cooperate when leaves 1 and 2 are brought into facing relationship.
  • Frame separator 30 comprises an I-beam with a portion of the lower flange and web' cut away as shown in FIG. 1.
  • a horizontal plate 56 is connected to the remaining vertical web of frame separator 30.
  • Mounting plate 58 is connected to the underside of plate 56 by means of bolts 60.
  • a pivot plate 62 having an opening (not shown) therethrough depends vertically from mounting plate 58.
  • pivot plate 62 carries a bronze bushing (not shown).
  • a pedestal 64 which includes an l-I-beam 66 and a mounting plate 68 secured thereto.
  • a pair of upright, spaced, parallel plates 70 are connected to mounting plate 68 and are arranged on either side of pivot plate 62. Plates 70 each have an opening (not shown) aligned with the opening in pivot plate 62.
  • a shaft assembly 69 is inserted into the aligned openings in plates 70, pivot plate 62 and/or the bushing carried by pivot plate 62.
  • Shaft assembly 69 is fixed in place by keeper pin 72.
  • pivot plate 62 (and thus leaf 1) is rotatable about shaft assembly 69.
  • Rotation of leaf 1 is accomplished by means of a pair of upright hydraulic lift cylinders 74 positioned beneath the two central frame separators 32 and 34.
  • Each cylinder 74 is pivotally mounted to the overhanging portion of base 18 at the upper portion of the cylinder barrel; the cylinder barrel extends through an opening in base 18 and into pit 10.
  • the pivotal mounting of each cylinder 74 includes lugs 76 extending from opposite sides of the cylinder barrel and mounted in trunnions (not shown) carried by a pair or upright brackets 78 mounted to base 18.
  • the ends of piston rods 80 associated with cylinders 74 are clevis mounted to the underside of their corresponding frame separators 32 and 34 as shown diagrammatically at 82.
  • the slab handling unit 23 may be situated under a crane girder or on a centerline of two adjacent buildings in space usually considered dead because of the crane hook approach. In the latter situation, the slab handling unit 23 could be used as a means for transferring slabs from one building to another.
  • a workpiece conditioning tool platform generally designated by the reference numeral 95, is suspended above slab handling unit 23 and adapted to traverse the approximate longitudinal centerline of base 18.
  • workpiece conditioning tool platform 95 includes an enclosed, air-conditioned pulpit 96 suspended above slab handling unit 23.
  • Pulpit 96 is intended to carry an operator and suitable controls to perform the functions described hereinafter.
  • Pulpit 96 is movable vertically by means of a pair of hydraulic or electric cylinders 98 mounted between pulpit 96 and pulpit support member 100. Other suitable means may be employed to provide vertical motion to the pulpit.
  • Pulpit support member 100 is rotatably mounted for at least 180, but preferably 270, of rotation by well known means to a carriage member 102.
  • Carriage member 102 is suspended from transverse rails 104 and able to move laterally therealong by means of suitable rollers (not shown).
  • Rails 104 are suspended from longitudinal girders 106 and adapted for longitudinal movement thereon by means of rollers 108. Electric power, oxygen and fuel are supplied to pulpit 96 through flexible conduits 110, 112 and 114, respectively, each having swivel means 116 therein. Conduits 110, 112 and 114 may be fed from reels or festooned above girders 106. FIG. 1 also shows an overhead crane hook 118 suspending an electric magnet 120 at the closest possible relative point of approach to pulpit 96. Pivotally mounted at the lower portion of pulpit 96 is a workpiece conditioning tool 122, in this case depicted as a scarfing torch. Workpiece conditioning tool 122 is designed to be manipulated and controlled as desired by the operator in pulpit 96.
  • Pulpit Position 1 is adjacent control station 124 which has the controls necessary to actuate slab handling unit 23.
  • Control station 124 is designed to permit the operator to manipulate the controls without leaving his station in pulpit 96.
  • An identical control station 126 is located at the opposite side of slab handling unit 23, adjacent Pulpit Position 2.
  • Metal slabs requiring conditioning are delivered to slab handling unit 23 on delivery table 128. Movement of slabs on delivery table 128 may be facilitated by rollers as shown or other suitable means. With leaves 1 and 2 in the horizontal positions shown in FIG. .1, magnet 120 lifts a first slab 130 from delivery table 128 and places it upon leaf 1 in a horizontal position with a longitudinal edge abutting faces 54 of slab stops 46, 48, 50 and 52. Instead of the crane and magnet shown, other suitable means may be employed to charge slabs to leaf 1 including platens having rollers or air bearings mounted thereon.
  • the operator next actuates lift cylinders 74 of leaf 1 to raise slab 130 to a position where it is inclined at about a angle (see FIG. 3).
  • the operator then rotates pulpit 96 to a position where conditioning tool 122 is substantially perpendicular to the inclined top surface of slab 130 (as shown in solid lines in FIG. 3).
  • the operator will then control pulpit 96 to traverse the length of slab 130 approximately above the centerline of base 10.
  • pulpit' 96 traverses the operator is able to maintain the conditioning tool generally in the same relative position to the inclined surface of slab 130 by manipulating his controls of the position of (i) pulpit lift cylinders 98, for vertical movement and (ii) carriage member 102, for lateral movement.
  • the maintenance of this relative position is especially important in conditioning operations such as scarfmg, grinding, in-
  • the top surface of slab 130 is very close to the wear plates 38, 40, 42 and 44 of leaf 2; and practically all of the weight of slab 130 is being borne by slab stops 46, 48, and 52 of leaf 1. It should be noted that in this position, the slab stops of leaf 1 are elevated slightly above the slab stops of leaf 2. Also, the offset positions of the slab stops on the facing leaves permit them to overlap and thereby makes possible the close relationship of the top surface of slab 130 to the wear plates of leaf 2. This feature affords a relatively soft" transfer of slab 130 to leaf 2 as next described.
  • both leaf 1 and 2 The operator then actuates the lift cylinders of both leaf 1 and 2 to cause them to move together toward leaf 2 while maintaining a substantially parallel relationship.
  • the front surfaces 64 of the slab stops of both leaves will be about leaf 1 is serving only to steady slab 130.
  • leaf 1 has rotated slightly more than 90 degrees from its original horizontal position, the operator stops rotation of leaf 1 but continues the downward rotation of leaf 2 until the bottom surface of slab 130 is inclined at an angle of about 45 (see FIG. 6). At the same time, the operator returns leaf 1 to its original horizontal position for receiving a new slab.
  • the operator continues the traverse of pulpit 96 until it reaches either Pulpit Position 1 or Pulpit Position 2.
  • the operator actuates controls at control station 124 or 126 to continue the rotation of leaf 2 until it reaches the horizontal position (see FIG.
  • Magnet 120 lifts slab 130 from leaf 2 and places it on exit table 132 of similar construction to delivery table-128. Slab 130 is then moved away from slab handling unit 23 for further processing. The operator may then repeat the entire operation just described with respect to a second slab. It should be mentioned that one or more cranes may be used to carry magnet 1'20 and these may be (an most likely are) operated independently of pulpit 96. Thus,.when the operator of slab handling unit 23 has completed the conditioning of a first slab, a second slab already will have been placed into position on leaf 1. Thus, the time required to load and unload slabs from slab handling unit 23 is essentially integral with operating time.
  • the operator in pulpit 96 is able to perform a discriminate scarfing operation, for example, on a hot slab. Further, he can carry out the operation without being subject to heat and noxious fumes and can turn the slabs without a dangerous lifting operation as is now commonly practiced. Further, he is not subjected to fatigue of heavy manual work, thus increasing his personal productivity. Further, because the tool is mechanically mounted rather than manually held as in present practice, he can employ larger, heavier tools thus enhancing personal productivity.
  • a further advantage may be realized with the slab handling unit of the present invention if, for example, it is located near the run-off table of a continuous slab caster. Ordinarily, after slabs emerging from a continuous caster are sheared, they are stacked horizontally on a rail car andmoved to a yard for air cooling. This coolwould be omitted.
