Definitions

  • my inlet construction is particularly useful as applied to a vessel which receives molten metal from a bottom-pour teeming vessel.
  • the steel may be teemed from a ladle or tundish into a receiving vessel which is maintained under vacuum.
  • the teeming vessel has an outlet opening in its bottom wall and a closure mechanism for controlling flow of metal through this opening.
  • To maintain the vacuum it is necessary to provide an enclosed passage between the two I yessels.
  • the enclosed passage is in the form of a tube which extends downwardly from the teeming vessel into the receiving vessel, or into contact therewith.
  • An object of my invention is to provide an improved inlet construction applied to a receiving vessel to furnish an enclosed passage from a bottom-pour teeming vessel.
  • a further object is to provide an inlet construction which furnishes an enclosed passage for use with a sliding gate or other closure on a teeming vessel, yet does not necessitate any special design of closure on the teeming vessel.
  • a more specific object is to provide an inlet construction which includes an enclosed tube mounted on a receiving vessel for axial movement, and means urging the tube into engagement with the underside of a teeming vessel.
  • FIG. is a vertical sectional view of portions of a teeming vessel and a receiving vessel, the latter being equipped with my improved inlet construction.
  • the drawing shows portions of a teeming vessel 10 and receiving vessel 12, both of which are refractory lined for containing molten metal.
  • the bottom wall of the teeming vessel has an outlet opening 113 and carries a nozzle 14 fixed to its underside aligned with the opening.
  • a sliding gate closure member i is mounted beneath the nozzle and has an opening M which can be aligned with the nozzle opening to permit teeming.
  • the gate can be supported and operated in any desired manner; hence l have not shown the supporting and operating mechanism.
  • the top wall of the receiving vessel 12 has a metal cover plate 17 and an inlet opening 118 through the cover plate and refractory lining.
  • 1 mount a refractory tube 21 in the opening lb.
  • the tube is axially movable and it has a metal casing 22 over the portion which extends upwardly of the vessel wall.
  • I affix lower and upper annular collars 23 and 24 to the cover plate 17 and to the upper end of the casing 22 respectively.
  • a compression spring 25 encircles tube 21 and bears at its ends against the two collars and thus urges the tube upwardly with respect to the vessel.
  • the confronting faces of the collars have annular grooves which receive lower and upper annular followers 28 and 29 respectively.
  • An expansible metal bellows 3b is joined at its ends to the two followers and encircles tube 21 within spring 25.
  • the bellows provides a seal around the outside of tube 21 and prevents loss of vacuum or escape of any special atmosphere used in vessel 12.
  • a cylindrical shield 31 rests on the cover plate 17 and surrounds the spring 25, bellows 3i) and tube 21.
  • the shield has an inlet 32 for admitting cooling air. For vessels not under vacuum or not containing any special atmosphere, l can omit the bellows.
  • Collar 24 carries a plate 33 fixed to its upper face. in the construction illustrated, the plate carries angle iron guides 34 for the sliding gate closure member 15.
  • a plurality of holddowns 35 are pivoted to the top of the cover plate 17 and are received in notches 36 in the side edges of plate 33.
  • the upper end of each holddown carries a pair of spaced collars 3'7 and 33, nuts 39 holding the upper collar, and a compression spring 40 between said collars.
  • the lower collar 37 bears against the upper face of plate 33.
  • the central portion of each holddown includes a turnbuckle 41 for adjusting the force of its spring All). In some instances 1 may omit the holddowns and rely on the weight of tube 21 to hold it in position.
  • l mount a plurality of auxiliary compression springs 42 between plates 17 and 33.
  • the respective plates carry a plurality of aligned upstanding studs 43 and depending eyebolts 44 which fit within the springs.
  • the eyebolts carry nuts 45 which bear against the upper ends of the springs and can be adjusted to regulate the force of the springs.
  • my invention affords a simple effective inlet construction for maintaining a sealed passage between a teeming vessel and a receiving vessel. Since all parts are located on the receiving vessel, it is not necessary to resort to any special design of teeming vessel, and the latter can be equipped with any desired form of closure.
  • a refractory lined bottom-pour vessel adapted to contain liquid metal and having a discharge opening in its bottom wall;
  • a refractory gate slidably mounted on the underside of the bottom wall of said vessel and having an opening adapted to be moved into and out of alignment with said discharge opening to control teeming of metal therethrough;
  • a refractory lined receiving vessel having an inlet opening in its top wall with which said discharge opening may be aligned
  • a refractory tube mounted for axial movement in said inlet opening and having a portion extending upwardly of the top wall of said receiving vessel into abutting relation with said gate;
  • a combination as defined in claim 2 in which the means against which said spring bears includes lower and upper annular collars encircling said tube and being affixed respectively to the top wall of said receiving vessel and to said tube adjacent its upper end.
  • a combination as defined in claim 2 comprising in addition auxiliary springs urging said tube upwardly with respect to said vessel.
  • a combination as defined in claim I. comprising in addition an expansible bellows encircling said tube in the space the outside of said tube.
  • said spring means is in the form of a compression spring encircling said tube
  • the means against which said spring bears includes lower and upper annular collars encircling said tube and being affixed respectively to the top wall of said receiving vessel and to said tube adjacent its upper end, and comprising in addition an expansibie bellows encircling said tube within said spring in the space between said collars and furnishing a seal around the outside of said tube.
  • a combination as defined in claim 1 comprising in addition holddown means connected to the top wall of said vessel and to the upwardly extending portion of said tube to limit upward movement of said tube.
  • the means on the upwardly extending portion of said tube including a plate having notches in its side edges, said holddown means including tumbuckles pivoted to the top wall of said vessel and engaging said notches.
  • a combination as defined in claim 8 in which said vessel is refractory lined and adapted to contain molten metal, and said tube is of a refractory having a metal casing over the portion which extends upwardly from the top wall of said vessel.
  • a combination as defined in claim 8 comprising in addition a cylindrical shield surrounding said tube, and means on said shield for admitting cooling air.
