Definitions

  • ABSTRACT This invention relates to a mechanism for transporting steel sections through quenching tanks as they leave the finishing mill in a hot state.
  • the invention provides a cylindrical framework rotatable in a housing and having a number of sets of arms outstanding from its periphery.
  • a fixed arcuate rack is interleaved with these arms and extends from an exit station on one side of the framework towards an entry station on the opposite side.
  • the arrangement is such that the steel billets/slabs are individually deposited on the trailing faces of selected sets of the arms at the entry station and as the framework rotates they are carried downwardly towards the rack and then driven upwardly along it by the leading faces of the succeeding set of arms, the rake of these arms at the exit station being such that they are discharged under gravity to a stacker mechanism.
  • This invention relates to transport mechanism, and more particularly relates to a mechanism for laterally transporting elongate members, e.g. steel billets or slabs.
  • The. invention is of particular utility in transporting such steel sections through quenching tanks as they leave the finishing mill in a hot state.
  • billets or slabs are usually transferredtby chain conveyorfrom the roller table into and through thequenching tank before stacking, or in some cases by a rotatablexdrum having discrete radial receptacles for the steel sections which are retained in place by pivotal. latches.
  • the present invention consists in a mechanism for laterally transporting elongate members, comprising a cylindrical framework rotatable in a housing and having a plurality of sets of armsregularly spaced around, and outstanding from, it periphery, and a fixed arcuate rack interleaved with the arms on the framework and extending from an exit station adjacent one side of the framework towards an entry station opposite thereto, the arms being racked in a common sense so as to in cline upwardly at the entry station and downwardly at the exit station, the arrangement being such that the elongate members are individually deposited on the trailing faces of selected sets of the arms at the entry station and, as the framework rotates, carried on these faces downwardly towards the rack and then driven upwardly along the rack by the leading faces of the succeeding set of arms whereby to be discharged therefrom under gravity at the exit station.
  • the elongate members may be steel bars, billets or slabs etc. and, as mentioned. this invention is applicable to quenching these sections in which case the housing" may constitute a tank for the quenching medium, e.g. water, the axis of rotation of the cylindrical framework lying above the water level.
  • the quenching medium e.g. water
  • the entry andtexit stations may be at different levels as desired or they may be diametrically opposite each other on a level plane roughly in line with the axis of rotation, and the outstanding arms may each embody an inturned lip on the extremity of their trailing face to retain the sections over substantially the whole of the first quarter turn of travel in this event the rack need only extend back from the exit station over little more than the second quarter turn of travel to provide a slight overlap
  • the tank may be made to any convenient shape since it fulfills no part in supporting the steel sections; it may thusbe designed with adequate capacity to accommodate the sludge without interfering with the rotatable framework although, of course, contrary to the known arrangements discussed above, there are no separately movable parts to contend with on this mechanism.
  • the tank may, for example, conveniently incorporate a sloping pit for collecting the sludge.
  • Conventional dog drive means may be provided for loading the sections at the entry station and similarly, conventional stacking means may be provided at the exit station.
  • FIG. 1 is a sectional side elevation of the mechanism
  • FIG. 2 is a section along II-Il in FIG. 1.
  • a cylindrical frame work 3 is mounted for rotation in the direction shown abut bearing journals 4 secured to a rectangularsection quenching tank 5.
  • An entry station 6 embodying a roller table 7 and a pusher arm/ducking dog 8 is mounted on one side of the framework and an exit station including a stacker mechanism 9, which is indicated purely schematically, is mounted on the opposite side.
  • the cylindrical framework comprises a hollow shaft 11 to which is secured at axially spaced intervals at number of fabricated disc-like structures 12 from which a plurality of arms 13 extend. These arms are all raked in a common sense at an angle inclined to the normal and carry at their extremities buttresses or lips 14.
  • a rack 16 comprising a number of arcuate quadrant rails 17 extending into the tank and secured to the bottorn by brackets 18 depends from an exit table 19 which, in turn, is secured to the top of the tank. These rails are interleaved" with the arms 13 of the framework so as to allow the latter freedom to rotate.
  • the quenching tank is filled with water 21 to a level below that of the axis of the framework.
  • this framework or wheel rotates slowly in steps in the direction shown and, as illustrated, hot steel slabs 22 are transported in a direction perpendicular to the plane of the drawing along the roller table 7.
  • the leading slab is arrested alongside the wheel and, in the dwell period during its rotation the pusher arm (8) is actuated, the dog driving the slab on to the trailing faces of the appropritate set of arms 13 over the end of the buttresses and, on its return, pivotally ducking under any obstruction in its path such as the succeeding slab length.
  • the loading cycle is repeated during each interval, and the slabs are immersed in the quenching water.
  • the angle of inclination of the arms is such that the slabs enter the water in a substantially horizontal mode and they are arranged to be completely submerged in the rotational movement between two successive steps or dwell periods.
  • the slabs are then lifted free from the water and finally, at the rail terminations, the inclination of the arms is such that the slab is deposited under gravity to the stacker mechanism 9 along the exit table 19. From here the slabs may be transported by chain conveyor or other conventional means to another location for subsequent operations such as straightening, inspection, deseaming or simply conveyance to stock.
  • a mechanism for laterally transporting elongate members comprising:
  • said rack means being positioned to support each elongate member while it falls from the trailing face of one set of arms to the leading face of the next set of arms as the framework rotates and carries said arms and the elongate members thereon first downwardly toward said rack means and then upwardly toward said exit station, and
  • said arm being raked in a common sense such that they incline upwardly when passing the entry station and incline downwardly when passing said exit station to discharge said elongate members by gravity.
  • a mechanism according to claim 3, wherein ach of the outstanding arms comprises an inturned lip on the extremity of its trailing face whereby to retain the members over substantially the whole of the first quadrant of travel from the entry station.
  • a mechanism for laterally transporting and quenching hot steel sections issuing from a finishing mill, comprising:
  • said rack means being positioned to support each elongate member while it falls from the trailing face of one set of arms to the leading face of the next set of arms as the framework rotates and carries said arms and the elongate members thereon first downwardly into said tank toward said rack means and then upwardly toward said exit station, and
  • said arms being raked in a common sense such that they incline upwardly when passing the entry station and incline downwardly when passing said exit station to discharge said elongate members by gravity.
  • a mechanism according to claim 8 comprising an inturned lip on the extremity of the trailing face of each of the said arms whereby to retain the sections throughout the course of their travel to the tank.
  • entry and exit stations are located at levels different both from one another and from a horizontal plane 3 ,779 ,O 34 Y 5 6 containing the axis of rotation of the cylindrical framea plurality of disc-like structures axially spaced along work. i I the shaft and from which the said arms extend.
