Definitions
- This invention relates to bottom pour vessels adapted for use in the continuous casting of steel, and more pa.r ticularly to means for controlling the rate of discharge of the molten steel from such vessels.
- Stopper rods such as those commonly used on bottom pour ladles are not suitable for either tundishes or vacuum degassing vessels for several reasons.
- a stopper rod is not suited for use in a degassing vessel, because the stopper rod and associated mechanism for its operation are located partly inside and partly outside the vessel, requiring a vacuum tight seal.
- the apparatus of this invention includes a bottom pour vessel having a discharge nozzle in the bottom wall thereof and means for controlling the discharge of molten steel through said nozzle comprising a slidable refractory closure member, means for sliding the closure member into and out of nozzle closing position, and means for holding the closure member against the exterior end of the nozzle.
- the closure member is a slidable refractory block having an imperforate portion and a teeming opening for closing and opening the nozzle, respectively.
- the closure member comprises a plurality of separate refractory plates including an imperforate plate for closing the discharge nozzle and a plate having a teeming opening for controlled discharge of steel.
- FIG, 6 is a sectional view taken along line 66 of FIG. 4.
- FIG. 7 is a sectional view of a detail taken along line 77 of FIG. 4.
- FIG. 8 is an elevational view of a vessel having the closure device of this invention mounted on the exterior thereof shown in a position above a continuous casting mold.
- 10 is a refractory lined bottom pour vessel, such as a degassing vessel or tundish, which is adapted to contain molten steel.
- Vessel 10 has a bottom wall 11 which has a nozzle 12 for the discharge of molten steel from the vessel.
- Nozzle 12 is a sleeve shaped member, defining a cylindrical bore 13 and hav ing a flat exterior end 14 which is adapted to receive a refractory closure member in sliding contact. Because of the extreme amount of wear to which nozzle 12 is subjected, it is desirable to make this nozzle of a refractory which is more resistant to erosion than the refractory which lines the interior of vessel 10.
- Vessel 10 in the embodiment of FIGS. 1-3 includes means for controlling the discharge of molten steel through nozzle 12 comprising a slidable refractory closure member 15 mounted on the exterior of vessel 10.
- Closure member 15 is movable between nozzle-opening position, in which steel is discharged at a controlled rate from vessel 10, and nozzle-closing position in which the discharge of molten steel from vessel 10 is prevented.
- Closure member 15 is in the shape of a rectangular block or panel 15 having a flat upper surface 16 which is adapted to make sliding contact with the exterior end surface 14 of nozzle 12.
- Refractory block 15 includes a tubular nozzle insert 17 defining a restricted opening 18 for teeming of molten steel, a second opening 19 which is of the same diameter as the bore of nozzle 13 for preheating the vessel, and an imperforate central portion 20 located between teeming opening 18 and large opening 19 for closing of nozzle 12 so as to prevent discharge of molten steel'from vessel 10.
- Nozzle insert 17 is preferably made of a refractory which is more resistant to erosion than the refractory material of which the'remainder of closure member 15 is made. Opening 19 of large diameter is used only when vessel 10 is empty, and serves primarily to permit preheating of vessel 10.
- L-shaped angles 21 are provided along the outer edges-of closure member 15 around the entire perimeter thereof in order to provide support for and prevent chipping of the edges.
- a plurality of metal flanges 22, welded to angles 21 and extending outwardly therefrom provide contact surfaces for engagement by supporting members which hold closure member 15 in contact with the exterior end 14 of nozzle 12, as will be hereinafter described.
- closure member 15 Sliding movement of closure member 15 means of a fluid pressure cylinder 26, which is supported by trunnions 27 on U-shaped bracket 28, which in turn is afllxed to mounting bracket or flange 29 secured to the side of vessel 10.
- Cylinder 26 has a piston rod 30 extending therefrom in one direction. This piston rod 30 teris eifected by minates in a yoke 31 which is secured by pin 32 to tongue 33, which in turn is welded to angle member 21.
- a metal plate 40 of generally rectangular cross section is afiixed to the exterior side of the bottom Wall of vessel by means of screws 41.
- This plate 40 carries the structure 42 which holds refractory block against the exterior end 14 of nozzle 12.
- This support structure 42 includes a plurality of spring loaded levers 43 on either side of nozzle 12.
- Levers 43 are pivotally mounted near their centers on a pair of longitudinally extending rods 44, one on either side of nozzle 12.
- Rods 44 are supported from plate 40 by means of tongues 45.
- the outer ends of levers 43 are urged downwardly by compression springs 47. This causes the inner ends of levers 43 to press upwardly against lugs 22, thereby holding refractory closure member 15 in fluid-tight engagement against the lower end 14 of nozzle 12.
- Compression springs 47 are located between plate 40 and retainer plates 48, urging the latter downwardly.
- the compressive force of springs 47 is transmitted to levers 43 through set screws 49, which are received in screw-threaded sockets in levers 43 and which terminate at their upper ends in ball joints 50 mounted in swivel sockets 51 on retainer plates 48, providing operative connections between springs 47 and levers 43.
- the compressive force exerted by springs 47 can be regulated by adjustment of the positions of set screws 49.
- Levers 43 have recesses 52 at their inner ends for receiving metal rods 53 which preferably extend longitudinally. One of these rods 53 is located on either side of nozzle 12.
- Metal rods 53 are welded to bars or rails 54 positioned below lug 22 and having upstanding flanges along both sides.
- a pad 55 of graphite or other suitable lubricating material is preferably interposed between bar 54 and flange 22.
- closure member 15 is moved to nozzle-closing position by appropriate actuation of cylinder 26 before any molten steel is poured into vessel 10. Molten steel is then poured into vessel 10. The nozzle opening 13 is then placed over the receptacle which is to receive molten steel, as for example a continuous casting mold. Closure member 15 is then moved to nozzle-opening position, in which opening 18 is aligned with nozzle opening 13, by appropriate actuation of cylinder 26. When it is desired to cut off flow of molten steel from vessel 12, refractory closure member 15 is again moved to nozzle-closing position as shown in FIG. 2. Limit stop 56 prevents accidental alignment of large diameter opening 19 with nozzle opening 13.
- the closure member 15 provides a fluid-tight closure for vessel 10, and is therefore particularly well suited for use on vacuum degassing vessels.
- This closure member is free from operating difliculties due to freezing steel, since the sliding movement of the closure member prevents accumulation of molten steel between the closure memher and the exterior end 14 of nozzle 12.
- the exterior location of closure member 15 permits rapid replacement, minimizing the length of time the vessel 10 is out of service for such replacement.
- the modification illustrated in FIGS. 4 to 7 permits replacement of worn flow-control and closure members without shutdown of the vessel.
- This modification also makes it possible to teem molten steel at different rates.
- the means for controlling the discharge of molten steel comprises a plurality of separate refractory plates, including an imperforate closure plate 60 and a flow-control plate 61 having a teeming opening 62 therein.
- Both plates 60 and 61 are flat square or rectangular plates having guide ways 61a along their lower outside edges. Means are provided for sliding these refractory plates successive-' sively into and out of position beneath nozzle 12 so as alternately to open and close discharge opening 13.
- a plurality of flow-control plate-s 61 having teeming openings 62 of different diameters permits control of the discharge rate of molten steel from vessel 10.
- the structure of bottom-pour vessel 10, which has a refractory-lined outer wall structure'including a bottom wall 11 having a nozzle 12 therein, may be identical to that described in connection with FIGS. 1 to 3.
- Refractory plates 60 and 61 are moved in a linear path into and out of position beneath nozzle opening 13 by means of a fluid pressure cylinder 26 and pusher 63.
- Cylinder 26 has a piston rod 30 which terminates in tongue 31.
- Pusher 63 extends the entire width of plates 60 and 61 and is secured to tongue 31 by pin 64. This pusher 63 is adapted to contact the edge of refractory plate 60 or 61 and to push a series of such plates in edge-to-edge engagement in a linear path away from cylinder 26.
- a pair of guides 65 extending parallel to the axis of cylinder 26 are provided for guiding the movements of refractory plates 60 and 61 into and out of engagement with the exterior end 14 of nozzle 12. These guides include graphite bars 67 and metal supporting bars or rails 66, both of rectangular cross section. Supporting bars 66 are welded to rods 53 to prevent lateral movement.
- At least one imperforate plate 60 and one plate 61 having a teeming opening are placed on guides 65.
- Pusher 63 contacts an edge of one of these plates, pushing both plates in edge-to-edge engagement along guides 65 away from cylinder 26.
- Nozzle opening 13 is alternately opened and closed by placing first a flow control plate761 and then an imperforate plate 62 in contact with the exterior end 14 of nozzle 12.
- a plurality of imperforate plates 60 and flow-control plates 61 may be placed in alternating sequence on guides 65.
- Two successive flow-control plates 61 may also be placed on guides 65, as for example when an eroded flow-control plate 61 is being replaced;
- a table of 68a having a pair of laterally extending guides 68 provides a convenient means for placing refractory plates 60 and 61 on longitudinally extending guides 65 in a position Where they may be contacted by pusher 63.
- the structure 42 for maintaining refractory plates 60 and'61 in contact with the exterior end 14 of nozzle 12 is the same as the corresponding structure 42 illustrated in FIGS. 1 to 3.
- FIGS. 4 to 7- permits changing of Howcontrol plates 61 Without interruption of use of vessel 10.
- a plate 61 becomes eroded and is no longer useful, or in the event opening 62 becomes partly obstructed by skull or non-metallic inclusions, the defective plate 61 is moved out of the way and a new plate 61 substituted in its place by sliding the plates along guides 65.
- a vessel 10 is positioned so that nozzle 12 is directly above a receptacle, such as a continuous-casting mold, which is to receive steel from the vessel.
- a receptacle such as a continuous-casting mold
- an imperforate closure plate 60 is placed over nozzle opening 13 to prevent discharge of steel until vessel 10 is filled to the desired operating level.
- a uniform operating level in vessel 10 is desirable in order to maintain a constant discharge rate.
- Imperforate refractory plate 60 is pushed out of position beneath nozzle 12 and flowcontrol plate 61 having a teeming opening 62 is pushed into position by pusher 60 to initiate pouring.
- plate 61 is pushed out of position and an imperforate plate 60 is pushed into position by pusher 63.
- FIGS. 4 to 7 readily permits controlling of teeming rates, simply by use of a plurality of plates 61 having openings 62 of different diameters.
- a bottom pour vessel 10 having a closure device as illustrated in FIGS. 4 to 7 is positioned so that the discharge nozzle 12 is directly above a vertical tubular open-ended Water-cooled continuous-casting mold 70.
- the nozzle 12 is closed by means of an imperforate refractory plate until it is desired to pour molten steel into mold 70.
- cylinder 26 is actuated so as to push refractory plate 60 out of the way and push a flow-control refractory plate 61 having a teeming opening therein into position beneath nozzle 70. This permits teeming of molten steel into the mold 70 at a controlled rate.
- the teeming rate depends on the diameter of the teeming opening 62 in refractory plate 61.
- a second refractory plate 61 is substituted therefor simply by pushing the old plate 61 out of the way and pushing the new plate 61 into its place.
- an imperforate plate 60 is pushed into position beneath nozzle 12 in place of the refractory plate 61 having a teeming opening.
- Vessel 10 has been illustrated as a vacuum degassing vessel in FIG. 8.
- vessel 10 may be any type of vessel suitable for containing molten steel, as for example a tundish.
- the present invention has been described with particular reference to apparatus for handling molten steel, it will be understood that the invention is applicable to high-temperature apparatus for handling other molten metals.
- FIG. 8 illustrates a closure device for the embodiment shown in FIGS. 4 t 7, it will be understood 35 that the closure device shown in FIGS. 1 to 3 may be provided on the exterior of vessel 10 instead.
- a bottom-pour vessel for teeming steel having a 4 nozzle in the bottom thereof and a panel slidable on said bottom to control flow through said nozzle, the improvement comprising a row of levers of the first class pivotedly attached to the bottom of said vessel on each side of said panel normal to the path thereof, a rail on each side of said panel parallel to said path engaged and supported by the inner ends of the adjacent levers, a bearing surface on each side of said panel engaged and supported by the adjacent rail, and means urging the outer end of each lever downward.
