Definitions

  • United States Patent O U.S. Cl. 239-53 12 Claims ABSTRACT OF THE DISCLOSURE Apparatus for adjusting the orientation of a jet of molten metal issuing from an outlet opening of a container, such as a tun dish, includes a positioning element, having a discharge aperture therethrough, adjustably mounted downstream of the outlet opening with the aperture communicating with the latter for flow of molten metal serially through the outlet opening and the aperture.
  • the cross sectional ilow area of the discharge aperture is less than that of the outlet opening, and means are operable to adjust the positioning element relative to the outlet opening to adjust the orientation of the molten metal jet.
  • Means are also provided to cooperate with the discharge aperture to control the rate of ilow of molten metal therethrough.
  • This invention relates to .an apparatus for altering the position of a jet of molten metal, especially for continuous casting machines.
  • the ilow within the liquid core of a continuously cast strand caused by the impact of the jet of molten metal, and its temperature, can inuence the formation of the solidified shell of the strand. For instance, erosion could take place on the inner side of the shell, weakening it to the extent that the ferrostatic pressure in the liquid core could cause one of these dangerous breakouts of the molten metal.
  • the jet of molten metal is adjusted in relation to the mold section so that the flow in the liquid core, caused by the impact of the jet molten metal, does not decisively damage the solidi-tied shell.
  • a deviation of the jet of molten metal with magnetic means has also lbeen suggested. Such a deviation is relatively complicated and expensive. As a change of position is also caused when a change of direction of the jet is effected, the disadvantages would be that by the change of the angle of impact of the jet on the level of liquid metal the flow pattern within the liquid core could deteriorate.
  • the aim of the present invention is to obtain an apparatus for altering the position and direction of the jet of molten metal which ows out of a container without influencing the rate of ilow through the nozzle.
  • a sliding plug is preferred for a container, whereby the opening in the container preceding the positioning element has a minimal size corresponding to approximately the sum of the maximum sliding distance of the element plus the diameter of its opening.
  • FIG. l is a tundish with a sliding plug and its device to alter the position of the jet of molten metal rby displacing it in one direction;
  • FIG. 2 is a section on line II-II of FIG. l;
  • FIG. 3 is an embodiment according to FIG. 1 with an inclined hole for the jet of molten metal
  • FIG. 4 is a tundish with a sliding plug and its device to alter the position of the jet of molten metal in two directions;
  • FIG. 5 is a section on line V-V of FIG. 4;
  • FIG. 6 is a positioning element with branched ofi discharge openings
  • FIG. 7 is an embodiment with an extension tube
  • FIG. 8 is an embodiment similar to the one of FIG. 7;
  • FIG. 9 is a tundish with stoppered nozzle and a device to change the position of the jet of molten metal along a circular path;
  • FIG. l0 is a tundish with a of the and FIG. ll is a section on line XI-XI of FIG. l0.
  • FIGS. l and 2 show part of a tundish 1 lined with refractory material 2 with an opening 2 accommodating a spout 4 which has a longitudinal opening 11.
  • the face 5 ot the spout is accurately machined, for instance ground.
  • a sliding plug 6 is situated just underneath the spout 4.
  • This sliding plug consists of a positioning element 7 with an opening 8 for the flow and is followed by a closing element 9 with a discharge opening 10.
  • These elements consist of refractory material embedded in a steel frame.
  • the opening 10 can also consist of a separate nozzle of refractory material.
  • the positioning element 7 and the closing element 9 are guided in a guidance 12 which conof a sliding plug combined device for universal change position and direction of the jet of molten metal;
  • This guidance 12 can be displaced in a further guidance 13 which is rigidly connected to the tundish.
  • a hand wheel 17 is ixed on the spindle 16 having an external thread 18 at one end.
  • a nut 19, having an internal thread which corresponds to thread 18, consists of two halves 20 and 21.
  • the half 20 is connected with a lever 22 and the other half 21 is connected with a lever 23.
  • the lever 22 is connected with a bearing piece 24 and the lever 23 with a bearing piece 25. Both of these levers can pivot around an axis on these bearing pieces.
  • the bearing piece 24 is rigidly connected with the guidance 12, whereas the bearing piece 25 is mounted on the closing element 9.
  • FIG. 4 shows means to engage either half 20 or 21 or both together with the thread 18.
  • the guidance 12 with the elements 7 and 9 can be displaced into any position; also the closing element 9 can be displaced in relation to the positioning element 7.
  • the guidance 12 can be fastened onto the guidance 13 by a screw 26 when half 20 is disengaged. This is necessary to prevent that frictional forces can dislocate the positioning element 9.
  • the spout 4 must have an opening 11, the minimum length of which corresponds to approximately the sum of the maximuni sliding distance of the positioning element 7 plus the diameter of the opening 8.
  • an induction heating system could be built into this element.
  • the disadvantage of arranging the closing element 9 below the positioning element 7 is that when the iiow is changed or the tundish is opened or closed by the closing element, a change of position of the iet of molten metal occurs. To avoid such a change, the closing element 9 can be arranged above the positioning element 7.
  • FIG. 3 shows a similar embodiment to FIG. 1.
  • the difference consists in that the closing element 7 is follower by the positioning element 9.
  • the positioning element 9 has a declined discharge opening 35, which directs the jet of molten metal at any desired angle, resulting in a different ow pattern Within the liquid core of the strand which is advantageously adapted to the strands guided in curved strand guiding means.
  • the erosion of the solidiiied shell can thus be kept to a minimum.
  • the discharge opening could also at the beginning be perpendicular to the upper face of the positioning element 9' and afterwards change to an inclined direction. If, as shown in FIG. l, the closing element 9 is below the positioning element 7, any inclined discharge opening 35 should be located in the element 9.
  • FIGS. 4 and 5 show a device employing a sliding plug, where the jet of molten metal can be displaced laterally into any desired position.
  • the tundish can be opened and closed without any change in position of the jet of molten metal.
  • a spout of refractory material with a relatively large opening 41 is built into the opening 3 of the tundish.
  • a positioning element 42 is arranged underneath the spout 40.
  • An upper positioning plate 43 with a discharge opening 47 and a lower plate 44 with a discharge opening 48 are built into a steel housing. Both elements are made of refractory material.
  • the opening 48 can also be inclined to achieve the desired and above explained effect.
  • a closing element built inside a steel frame in which there is a closing plate 46 of refractory material with a discharge opening 49 is situated between the plates 43 and 44.
  • the closing element 45 can be adjusted relative to the positioning element 42.
  • a guidance 50 is attached to a tundish 1.
  • a guiding element 51 is guided in the guidance 50. This arrangement allows the positioning element 42 to be moved perpendicular to the direction of movement of the closing element 45.
  • tundish 1 Another guidance 55 is attached to the tundish 1. It takes a bearing piece 56 which accommodates a sleeve 57 which can be turned by the hand wheel 17. Inside this sleeve there is a spindle 58 having at one end a thread 59 and a square head 60. The end of sleeve 57 forms a shoulder 61 with a square socket which lits onto head 60.
  • This rack 65 can be put into mesh with a gear 66 fastened onto the sleeve 57.
  • the nut 19 which consists of two halves 20 and 21 corresponds to thread 59. Again, these halves 20 and 21 are connected with their corresponding lever 22 and 23.
  • the lever 22 is influenced by a magnet 70 and the -lever 23 by a magnet 71.
  • the magnet 70 is fastened onto the bearing piece 72 and the magnet 71 onto the bearing piece 73.
  • a spring 75 fastened on bearing piece 73 presses lever 23 onto the thread 59.
  • These levers pivot around bearings 76 and 77, respectively, mounted on the bearing pieces 72 and 73, respectively.
  • the bearing piece 72 is rigidly iixed with the closing element 4'5 and the bearing piece 73 with the positioning element 42.
  • the .square head 60 is engaged with the end of sleeve 57.
  • the springs 74 and 75 engage halves 20 and 21 with the spindle 58.
  • the positioning element 42 and the closing element 45 are displaced.
  • the bearing piece 56y can be moved in the guidance 55 by turning the hand wheel 17 together with the positioning device 42 which is fastened onto the spindle 58, nut 19 and bearing pieces 72 and 73.
  • the magnet 71 pulls the half 21 from the thread on the spindle 58, leaving the other half 20 engaged with this spindle.
  • the spindle 58 and the square head 60 By turning the hand wheel 17, the spindle 58 and the square head 60, the bearing piece 72 and the closing element 45 are displaced.
  • a device not shown on the drawings holds the positioning element 42 which otherwise could be dislocated by frictional forces between the plates 43 and 46 or 44 and 46.
  • the lower positioning plate 44 can be so high that the discharge opening 48 shortly below the contact area with the closing element 45 branches olf in at least two further discharge openings 48', whereby lthe section of these openings can be sized to accommodate any desired ilow.
  • This arrangement can be seen in FIG. 6i. It is especially important when casting heavy slabs. There is also the possibility to arrange the above ilow division inside the closing element which should then be situated below the positioning element.
  • FIG. 7 shows an embodiment of a sliding plug combined with an extension tube.
  • This extension tube 27 having an opening is built onto the closing element 9.
  • the exit opening 28 is located slightly above the level 52 of the molten metal 54 in a mold 53 and can also extend to below this level.

  • Another advantage of the embodiment shown on FIG. 8 is that the lower section 30 which wears more rapidly than the others, due to erosional effects of the surrounding molten metal 54, can be replaced by a new section without changing the other sections.
  • FIG. 9 shows an embodiment of a device which allows the position of the jet 0f molten metal to be altered when stoppered nozzles are used.
  • a spout 80* is built into the bottom of the tundish 1 which can be closed by a stopper 81. This stopper is controlled by known means.
