Definitions

  • ABSTRACT A slidable gate mechanism for controlling teeming of material from a bottom-pour vessel, and a method of controlling teeming.
  • the closure element is a disk which is mounted for rotational movement in a linearly reciprocable tray.
  • the disk has a teeming opening on its central axis movable into alignment with the vessel outlet, and an imperforate area movable under the outlet to close it. Each time the outlet is closed, the disk is indexed to present a fresh portion of the imperforate area to the outlet, thus prolonging life of the disk.
  • This invention relates to an improved slidable gate mechanism for controlling teeming of material from a bottom-pour vessel and to an improved method of controlling teeming.
  • our gate mechanism and method are particularly useful when applied to a metal-teeming vessel, such as a ladle or tundish. It is known to equip such vessels with either a linearly slidable gate or a rotatable gate for controlling teeming, as shown for example in James T. Shapland U.S. Pat. No. 3,352,465 or Lyman US. Pat. No. 3,430,644 respectively.
  • a linearly slidable gate may be either of the reciprocable type, as shown in Shaplands Figures 1-3, or of the slide-through type, as shown in Shaplands Figures 4-6.
  • a reciprocable gate has both an orifice and an imperforate area, either of which may be positioned under the vessel outlet, the former to permit teeming, the latter to close the outlet.
  • the intention is that each such gate may be used several times to open and close the outlet before the gate must be replaced, but the refractory of the imperforate area wears rapidly where it is exposed to hot metal at the outlet, and replacement soon becomes necessary.
  • Slidethrough gates are either orifice gates or blanks, one of which displaces the other to open or close the outlet. New gates must be inserted for each operation, and sometimes this is inconvenient.
  • a rotary gate has a plurality of teeming openings and imperforate areas therebetween. This is a costly arrangement, since a large plate or several plate sectors with multiple openings must be used. Most rotary gates do not permit throt tling of the pouring stream, that is, only partially opening the vessel outlet.
  • An object of our invention is to provide an improved slidable gate mechanism which overcomes the foregoing problems, that is, a reciprocable gate which presents a fresh portion of its imperforate areaunder the vessel outlet with each closing.
  • a further object is to provide an improved gate mechanism which embodies a rotatable closure disk within a reciprocable tray, and means for indexing said disk with each closing to present a fresh portion of the imperfrorate area under the vessel outlet.
  • a further object is to provide an improved method of controlling teeming of material from a bottom-pour vessel wherein we use a reciprocable gate, but present a fresh portion of the imperforate area of the gate under the vessel outlet each time we close the outlet.
  • FIG. 1 is a partly diagrammatic longitudinal sectional view of a portion of a bottom-pour vessel equipped with a slidable gate mechanism in accordance with our invention
  • FIG. 2 is a vertical section on line IIII of FIG. 1;
  • FIG. 3 is a horizontal section on line III-III of FIG. I;
  • FIG. 4 is a horizontal section similar to FIG. 3, but showing a portion of the disk broken away and the gate in position for teeming.
  • FIGS. 1 and 2 show a portion of a bottom-pour vessel which includes a metal shell 10, a refractory lining 12, and a refractory nozzle 13 fixed within the bottom wall.
  • a mounting plate 14 is fixed to the bottom wall surrounding the nozzle.
  • the vessel is equipped with our novel gate mechanism, but otherwise may be of conventional construction.
  • the gate mechanism of our invention includes a housing 17 which has outwardly extending flanges l8 and 19 along its sides attached to the mounting plate 14 with bolts 20 (FIG. 2).
  • the top and bottom faces of the housing have openings 21 and 22 respectively.
  • a tray 23 is mounted in the housing for linear reciprocable movement.
  • a double-acting fluid-pressure cylinder 24 (shown only diagrammatically) is fixed to one end of the housing and contains a reciprocable piston 25 and piston rod 26 connected to tray 23.
  • the interior of the housing has stops 27 to limit movement of the tray toward the right, as viewed in FIGS. 3 and 4, while the end wall of the housing limits movement toward the left.
  • a refractory closure disk 28 is mounted on tray 23 to rotate on a vertical axis, and at its side edges overlaps flanges l8 and 19 of housing 17.
  • the ends of the tray have upstanding arcuate flanges 29 and 30 which confine the disk.
  • the bottom of the disk carries a cylindrical pouring tube 31, which projects downwardly through an opening 32 in the bottom of tray 23 and through the aforementioned opening 22 in the bottom of the housing 17.
  • the disk and pouring tube have a teeming opening 33 which extends vertically along their control axis.
  • a refractory top plate 34 in the opening 21 in the top of housing 17 overlying disk 28.
  • the top plate has an orifice 35 aligned with the opening in nozzle 13.
  • Tray 23 has a plurality of spring housings 36 within which we insert respective compression springs 37. These springs act upwardly against the bottom of disk 28 and thus urge the disk into tight relation with the top plate 34, and the latter into tight relation with the lower end of nozzle: 13.
  • the outer circumference of disk carries a metal ring 40, which has internal detents 41 or equivalent engaging the disk to prevent relative rotation therebetween.
  • the outside of ring has a plurality of ratchet teeth 42, conveniently spaced 22-9: from one another.
  • a pawl 43 is pivoted to the upper face of flange 18 of the housing.
  • a spring 44 urges the pawl into engagement with the ratchet teeth.
  • a slidable gate mechanism for attachment to a vessel which has an outlet in its bottom wall for teeming material therefrom, said mechanism comprising supporting means for attachment to the vessel, a closure element, means mounting said element in said supporting means for both linear reciprocable movement and rotational movement with respect thereto, said element having a teeming opening and an imperforate area, means for moving said element linearly selectively to a position in which said opening is aligned with the outlet to permit teeming and positions in which portions of said imperforate area are under the outlet to close the outlet, and means for rotationally indexing said element to present a fresh portion of the imperforate area to the outlet as the outlet is closed.
  • said mounting means includes a tray linearly movable with respect to said supporting means, and said element includes a disk mounted in said tray for rotation on a vertical axis with respect thereto, said teeming opening being on the central axis of said disk.
  • said indexing means includes a ring carried by the outer circumference of said disk, spaced apart ratchet teeth on said ring, and a pawl mounted on said supporting means cooperable with said teeth to allow said disk to move to a position in which said opening is aligned with the outlet without indexing the disk, but to index the disk as it moves in the opposite direction to close the outlet.
  • said supporting means includes a housing having outwardly extending flanges adapted to be bolted to the vessel and openings in its top and bottom, said mechanism further comprising a top plate located within the opening in the top of said housing and having an orifice to be aligned with the vessel outlet.
  • said mounting means includes a tray linearly movable with respect to said housing, and compression springs mounted in said tray and bearing against said element to maintain said element in a tight relation with said top plate and said top plate in a tight relation with the vessel.
  • a method of controlling teeming of material through an outlet in the bottom of a vessel comprising linearly moving a reciprocable closure element between a position in which a teeming opening in the element is aligned with the outlet, and a position in which an imperforate area of the element is under the outlet to close the outlet, and rotationally indexing said element with each operation cycle to present a fresh portion there of to the outlet.
