Definitions

  • the invention relates to a protective device for a pouring jet emerging from a metallurgical vessel, in particular from a pouring ladle, with a shadow tube (protective tube) enveloping the pouring jet, which is attached to an articulated linkage which can be pivoted in any spatial direction.
  • the invention aims to avoid these disadvantages and difficulties and has the object to provide a protective device of the type described in such a way that the shadow pipe follow any position of the pouring stream, i. H. can take any positions at different distances from the mounting of the linkage supporting the shadow pipe.
  • the joint linkage has a first, vertically extending joint parallelogram, which is rotatably mounted with its vertically arranged web about a vertical axis, on the coupling of which is articulated a boom supporting the shadow tube, which is the rocker arm of a second four-bar linkage forms, the web of which is formed by a rocker of the first joint parallelogram.
  • a rocker of the first articulated parallelogram is advantageously extended over its web, a counterweight being arranged on the extension.
  • a rocker of the first articulated parallelogram is advantageously extended over its web, and interacts with a stop arranged on the web of this articulated parallelogram, which is preferably adjustable.
  • the web of the first articulated parallelogram is expediently rotatably attached to an intermediate vessel of a continuous casting installation, into which vessel the pouring stream flows.
  • a swing arm of the second four-bar linkage has an extension designed as an actuating lever.
  • the shadow tube can be supported on a centering projection of a slide closing an outflow opening of a pan and can be pressed on automatically by means of the counterweight, the shadow tube advantageously being rotatably mounted on the boom about its longitudinal axis.
  • the shadow tube if it is supported on the slide, can follow the slide when the slide is actuated while maintaining its position relative to the slide, without twisting between the slide and the shadow tube.
  • FIG. 1 shows a view of an intermediate vessel of a continuous caster from above and Fig. 2 shows a side view along the line 11-11.
  • Fig. 3 is a sectional view taken along the line 111-111 of Fig. 1.
  • FIG. 4 illustrates a section along line IV-IV
  • FIG. 5 shows a section along line V-V of FIG. 3.
  • FIGS. 6 and 7 show a further embodiment in a representation analogous to FIGS. 1 and 2.
  • FIG. 8 illustrates a detail of the suspension of the shadow pipe according to a further variant, FIGS. 9 and 10 sections according to lines IX-IX and X-X of FIG. 8.
  • the intermediate vessel designated 1 is inserted into an intermediate vessel holder 2, shown in dashed lines in FIG. 1, on which a lateral bracket 3 is arranged, which supports a column 4 which projects up to the height of the intermediate vessel 1.
  • a vertically oriented, first joint parallelogram 5 is rotatably mounted on this column 4, the axis of rotation 6 being directed vertically and coinciding with the web 7 of the joint parallelogram 5.
  • the coupling 8 of this joint parallelogram is therefore also directed vertically.
  • the joint axes connecting the rockers 9, 10 in the coupling 8 and the web 7 run horizontally.
  • a boom 11 is also rotatably mounted about a vertical axis 12.
  • a U-shaped shade tube holder 13 is detachably inserted on the arm 11.
  • This shade tube holder 13 can be secured in its axial position by means of a locking pin 14 and can be fixed against rotation about its axis 17 on the bracket 11 by an axially displaceable on the arm 11, insertable into a lateral tab 15 of the shade tube holder 13.
  • the arm 11 forms a rocker arm of a further four-bar linkage 20, which is advantageously also designed as a parallelogram.
  • the web of this second parallelogram 20 is by a rocker 9 of the
  • first joint parallelogram 5 is formed.
  • a further rocker 21 designed as an actuating lever is connected via a coupling 22 to the boom 11, i. H. the rocker of the second joint parallelogram 20 connected.
  • the rocker 9 of the first joint parallelogram 5 is extended beyond the web 7;
  • the extension 23 serves to receive a counterweight 24, which is dimensioned so that the shadow tube 19 is automatically pushed up with a certain force.
  • the extension 23 interacts with a set screw 25 mounted on the web 7 and forming a stop, by means of which the upward movement of the shadow tube is limited.
  • the web 7 projecting into the column 4 with a pin 26 is mounted on the column by means of an axial ball bearing 27.
  • the boom also has an axial ball bearing 28 with which it is supported on the coupling 8 of the first articulated parallelogram 5.
  • a slide 30 is arranged on the underside of a ladle 29 and is provided with a hollow centering projection 31 on which the shadow pipe 19 is aligned.
  • the shadow tube fits into the holder with play 32. Special sealing measures are not required.
  • the centering projection is arranged on a slide plate 34 which covers the pouring opening 33 of the pan 29 in the closed position.
  • the shadow pipe 19 is rotatably supported in the holder 13 by means of a bearing 35 about its longitudinal axis, as a result of which it always assumes the same position with respect to the centering projection 31 even when the slide is moved.
  • a rotation of the shadow pipe 19 with respect to the centering projection 31 about the axis of the pouring opening 33 of the pan (or about the longitudinal axis of the shadow pipe 19) is thus excluded.
  • the shadow pipe 19 can be adapted to various positions of the ladle pouring opening 33 in wide areas. It can be pivoted both about the axis of the web 7 of the first gel parallelogram 5 according to the arrows 36 and also about the axis 12 of the arm 11 of the first joint parallelogram 5 with the help of the second joint parallelogram 20 in the direction of the arrows 37.
  • the entire device is pivoted about the axis of rotation 6 after the shadow tube is disengaged from the centering projection 31 by lowering. has been.
  • the first articulated parallelogram 5 is mounted directly on the tundish 1 on a side bracket 38 of the same.
  • the shadow tube 19 is gimbal-mounted and rotatable, so that its position does not change relative to the slide when the slide is actuated, i. H. it occurs even when the slider is operated. no twisting between slider and shadow pipe.
  • the cardanic bearing allows the conical upper part 40 of the shadow pipe 19 to be precisely adapted to the centering projection 31 of the slide.
  • the shadow pipe 19 is inserted in a receiving part 41 which is rotatable relative to the shadow pipe holder 39 and is secured against falling out by means of a releasable sleeve 42 on this receiving part 41.
  • the receiving part 41 rests (rotatably) on a first hinge plate 43, which is pivotable about an axis 44 relative to a second hinge plate 45.
  • the second hinge plate is in turn pivotally attached to the shade tube holder 39 about an axis 46 oriented at right angles to the axis 44.
  • the invention is not limited to the exemplary embodiments shown in the drawing, but can be modified in various ways.
  • the device described can also be used for the pouring tube extending from the tundish into the mold.
