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 enveloping the pouring jet, which is fastened to an articulated linkage which can be pivoted in any spatial direction.
  • the invention aims to avoid these disadvantages and difficulties and has as its object a protection to design the device of the type described above in such a way that the shadow pipe can follow any layers of the pouring jet, ie can take any layers at different distances from the mounting of the linkage bearing 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 Gelenkparallelo g Rammes extended beyond the web of formed and cooperates with a web arranged on this parallel linkage stop which is preferably adjustable together.
  • 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 pipe can be supported on a centering projection of a slide closing an outflow opening of a pan and with means of the counterweight can be pressed automatically, advantageously the shadow tube is rotatably mounted about its longitudinal axis on the boom.
  • 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 casting installation from above and FIG. 2 shows a side view along the line II-II.
  • Fig. 3 is a sectional view taken along the line III-III 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 denoted by 1 is inserted into an intermediate vessel holder 2 shown in dashed lines in FIG.
  • 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.
  • That shadow Pipe 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 arm 11 by a pin 16 that can be axially displaced on the arm 11 and inserted into a lateral tab 15 of the shadow tube holder 13.
  • the cantilever 11 forms a rocker arm of a further four-bar linkage 20, which is advantageously also designed as a parallelogram of the links.
  • the web of this second parallelogram 20 is formed by a rocker 9 of the first parallelogram 5.
  • 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 articulated 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, which is provided with a hollow centering projection 31 on which aligns the shadow pipe 19.
  • the shade 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 over a wide range. It can be pivoted both about the axis of the web 7 of the first articulated parallelogram 5 according to the arrows 36 and also about the axis 12 of the arm 11 of the first articulated parallelogram 5 with the aid of the two articulated parallelogram 20 in the direction of the arrows 37.
  • the entire device is pivoted about the axis of rotation 6 after the shade tube has been brought out of engagement on the centering projection 31 by lowering.
  • 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 gimbaled and rotatably mounted, whereby its position does not change when the slide is actuated relative to the slide, ie there is no twisting between the slide and the shadow tube, even when the slide is actuated.
  • a precise adaptation of the conical upper part 40 of the shadow tube 19 to the centering projection 31 of the slide can be achieved by the cardanic bearing.
  • the shroud tube 19 is used according to this variant in a shadow with respect to the tube holder 39 rotatable 'accommodating portion 41 and secured by means of a detachable collar 42 of this receiving part 41 from falling out. The.
  • Receiving member 41 is at rest (rotatably) on a first hinge plate 43, which elenkplatte about an axis 44 opposite a second G 45 is pivotable.
  • the second hinge plate is in turn pivotally attached to the shadow tube holder 39 about an axis 46 oriented at right angles to the axis 44.
  • the invention is not restricted 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.
