Definitions

  • a bottom-pour teeming vessel for pouring molten metal into a mold is provided with a sliding gate or valve controlling the flow of metal and a nozzle extension tube depending below the gate.
  • a nozzle plate is secured to the vessel bottom and the sliding gate is urged thereagainst by spring cushions mounted on spaced rails one on each side of the vessel nozzle, and secured to the vessel bottom.
  • the cushions also mount an extension-tube holder below the gate and the upper end of the tube is secured thereon by a split clamping collar. The gate is thus free to slide between the nozzle plate and the upper end of the tube.
  • This invention relates to a bottom-pour teeming vessel for casting molten metal, i.e., a ladle, tundish or the like and, in particular, to a teeming vessel having a sliding gate or valve for controlling flow through a nozzle, and an extension tube depending therebelow.
  • I attach a nozzle plate having a port therein to the vessel bottom so that the port registers with the vessel nozzle.
  • the rails have spring cushions mounting ways on which a sliding gate or valve moves.
  • An extension tube holder is also supported on the spring cushions and a tube depending from the holder is secured thereto by a split clamping collar.
  • the sliding gate is free for movement between the nozzle plate and the upper end of the tube.
  • FIGURE 1 is a section through a portion of the bottom of a teeming vessel having the invention incorporated therein, taken at right angles to the path of movement of the sliding gate, with parts in elevation;
  • FIGURE 2 is a section taken along the plane of line II-II of FIGURE 1;
  • FIGURE 3 is a partial bottom plan view showing the extension tube and the split clamping collar which secures it to the tube holder.
  • a teeming vessel 10 has an outlet nozzle 11 in the bottom thereof.
  • a rectangular metal-framed refractory plate or slab 12 having a central hole in registry with the nozzle is confined in a rectangle of bars 12a and secured to the vessel bottom by means to be described shortly.
  • a rectangular flowcontrol panel or gate valve 13, also metal-framed refractory, is mounted by said means, for sliding movement across plate 12.
  • the valve 13 is one of two types, i.e., that is shown in the drawings with a central hole, or a solid blank which cuts off flow through the hole in plate 12. Valves 13 are pushed successively into position beneath plate 12 by a cylinder and piston (not shown) mounted on the vessel bottom.
  • Spaced parallel rails 15 are secured to the vessel bottom by bolts 16 extending through flanges on the rails and through bars 12a.
  • Spring cushions 17 are secured to the inner faces of the rails in spaced relation therealong.
  • Each cushion comprises a cartridge 18 having a plug 19 slidably received in its open upper end, and an adjusting screw 20 threaded into its closed lower end which is drilled and tapped to receive it.
  • a coil spring 17 is compressed between a thimble 21 resting on screw 20 and plug 19 which is anchored to the thimble by a central screw 22.
  • the plugs 19 of the several cartridges together support and continuously exert an upward pressure on an extension-tube holder 23 which is a rectangular frame including shoulders 23:: and a depending flange 23b. As shown in FIGURE 1 shoulders 23a rest on cushions 17, specifically on plugs 19.
  • a refractory extension tube 24 having ears 240: at its upper end is supported in the flange 23b of holder 23 by a split clamping collar 25, the segments of which are secured to the flange by screws 26.
  • the remaining space within shoulders 23a and flange 23b is filled with a plastic refractory mix 27 which sets and in which is embedded a central refractory block having a port therethrough.
  • my invention provides a sliding gate for a teeming vessel with an extension pouring tube which remains fixed in position though the gate is free to move and is firmly pressed against the vessel bottom (plate 12) at all times to prevent leakage.
  • SAMUEL F. COLEMAN Primary Examiner 2.
