Definitions

  • FIG. 1 A first figure.
  • FIG 3 INVENTOR EARL I? .S'HAPLA/VD Attorney OPERATING AND LOADING MECHANISM FOR SLIDABLE GATES This invention relates to an improved Operating and loading mechanism for slidable gates used as closures on bottom-pour vessels.
  • my operating and loading mechanism is particularly useful as applied to vessels for pouring molten metal, for example a ladle or tundish.
  • vessels for pouring molten metal, for example a ladle or tundish.
  • Such vessels have an outlet in the bottom wall through which molten metal is poured into a receiving vessel.
  • a slidable gate mounted on rails on the underside of the bottom wall for controlling flow of metal through the outlet, one example of which is shown in James To Shapland, US. Pat. No. 3,352,465.
  • the arrangement usually preferred is to use a series of gates, each of which is either a blank for closing the outlet or provides a nozzle for permitting pouring.
  • the vessel carries a hydraulic operating mechanism for shoving the different gates along the rails into vertical alignment with the outlet. As each new gate is shoved into position, it shoves the preceding gate past the outlet and ultimately off the rails.
  • An object of my invention is to provide an improved operating and loading mechanism which overcomes the foregoing problems, that is, which does not interfere with loading of new gates and permits use of gates of greater vertical dimension.
  • a more specific object is to provide an improved hydraulic operating mechanism which shifts out of the way of the rails to enable gates to be loaded without interference.
  • FIG. I is a top plan view of my operating and loading mechanism
  • FIG. 2 is a vertical section on line IllI of FIG. I, but showing the mechanism installed on a vessel;
  • FIG. 3 is an end elevational view from the right as viewed in FIGS. 1 and 2;
  • FIG. 4 is a vertical section on line IV-IV of FIG. 11;
  • FIG. 5 is a vertical section on line VV of FIG. 1.
  • FIG.. 2 shows a portion of a bottom-pour vessel which has a metal shell l2 and a refractory lining 13.
  • the bottom wall of vessel 10 has an outlet opening within which a nozzle 14 is mounted.
  • My operating mechanism includes a submounting plate 115, which I attach to the bottom of the vessel with bolts 16. These same bolts serve also to attach a mounting plate 17 to the underside of the submounting plate. Plates l5 and 17 encompass the lower portion of nozzle 14 beneath shell 12. I attach a pair of opposed guide rails 18 to the underside of the mounting plate 17 with bolts 19 (FIG. 3). Rails 18 have upper and lower inwardly directed flanges 2t) and 21.
  • the upper flanges 20 support a refractory plate 22 which has an opening 23 forming a continuation of the nozzle opening.
  • the lower flanges 21 support slidable gates 24 and 25.
  • Gate 24 is a nozzle gate which carries an extended pouring tube 26.
  • Gate 25 is a blank.
  • FIG. 2 shows the nozzle gate 24 positioned in alignment with the nozzle 14 for pouring, and the blank gate 25 in the ready position.
  • my operating mechanism hereinafter described, shoves the blank gate into vertical alignment with the nozzle.
  • the blank gate shoves the nozzle gate along the rails 18 past the outlet and ultimately off the far ends of the rails.
  • the submounting plate 15 carries a pair of elongated parallel tongues 29 which extend horizontally over the rails 18 and therebeyond.
  • the inner side edges of the tongues carry upright plates 30 which are braced at their upper edges by transverse bars 31. I further reinforce the structure with diagonal braces 32 bolted at their ends to plates 30 and vessel 10.
  • a pair of transverse shafts 33 and 34 extend between the two plates 30 near their upper edges. Shafts 33 and 34 carry pairs of links 35 and 36 respectively pivoted thereto at their upper ends adjacent plates 30 (FIG. I).
  • the lower ends of links 35 and 36 pivotally support a fluid pressure cylinder 37, which has flexible connections 38 and 39 for admitting and discharging fluid.
  • Cylinder 37 contains a reciprocable piston and piston rod 43.
  • the outer end of the piston rod carries a ram block 44. Lugs 45 project from opposite sides of the ram block (FIGS. 1 and 4).
  • a pair of books 46 are pivoted to the submounting plate 15 on pins 47. Plate 15 has slots 48 to accommodate the hooks. Plate 15 also carries a fixed stop 49 above rails 18 (FIG. 5).
  • my invention affords a simple mechanism for operating a slidable gate clo- I sure and overcoming the problems usually encountered.
  • the operating mechanism is completely out of the way while I load gates on the rails. Consequently I can use gates of any vertical dimension, including gates which have extended pouring tubes. Such tubes are particularly useful in installations which require that the pouring stream be shielded from the atmosphere.
  • the supporting means for said cylinder includes a submounting plate fixed to said vessel, upright plates fixed to said submounting plate, and links pivoted to said upright plates and to said cylinder.
