Definitions

  • the invention relates to a dip spout for casting metal, in particular Steel in continuous casting plants for thin slabs, with a circular one Cross section having a pouring part fastened to a pouring vessel and an in the pouring part immersed in a rectangular mold, the Mouth is equipped in a rectangular cross-section.
  • EP 0 630 712 describes an immersion nozzle, in particular for thin slab casting known, which is divided into two sections and the lower shape of a length has that is much larger than its width.
  • the individual sections are formed by separate shaped stones, the shaped stones on their each other facing ends engage one another and between the interlocking ends A seal is arranged at the ends of the shaped blocks.
  • the individual shaped stones show a complicated shape structure with clear Differences in wall thickness.
  • a ratio of less than 1: 1 between the flow cross-section in the inlet pipe and on Outlet of the immersion spout is caused by flow diversion and restriction of reached two mouth openings.
  • the aim of the invention is to provide a diving spout that is easy to manufacture, a has a long service life in terms of its manufacture and operation Low thermal stress structure and that a uniform outflow of liquid metal.
  • the invention achieves this goal by the in the characterizing part of Claim 1 specified features.
  • the immersion nozzle is made up of two basic components, one tubular pouring part and a straight pouring part. Between these two in their form completely different basic components is one with regard to its overall length short transition provided.
  • the flow of the liquid steel can be completely calmed down lead, as far as the flat wall elements each almost parallel to each other are arranged.
  • the flow conditions can be caused by Impact elements, which are arranged at the foot of the pouring part, had a positive influence become.
  • FIG. 1 shows a section of a pouring vessel 41 with the outlet opening 43, which can be blocked or constricted by a plug 42.
  • a pouring part 11 On the outside of the bottom of the pouring vessel, a pouring part 11 is attached, the has the shape of a tube and has flat end faces on the mouth side.
  • the tubular pouring part 11 has a substantially rectangular pouring part 21 connected.
  • the pouring part 21 dips into the melt S on the mouth side is in a mold 51.
  • the pouring part 21 has broad sides 22, shown in the left part of the drawing, and narrow sides 23, shown in the right part of the picture, as well as an end wall 27 in the connection point of the pouring / pouring part.
  • At least the pouring part consists of a material that can be heated by an energy that can be introduced from the outside.
  • the material can be a refractory material in which metallic elements are embedded, which can be heated by electrical energy.
  • a heating device 31 is shown as a sketch, which is guided essentially parallel to the broad sides 22.
  • the broad sides 22 and the narrow sides 23 are guided essentially parallel to one another and are at a distance a from one another in relation to a distance b of the narrow sides 23 in the mouth region of the immersion nozzle of a ⁇ 1 / 35xb.
  • an embodiment of the pouring part is shown in which the narrow sides 23 spread at an angle of ⁇ 7 ° C. in the direction of flow.
  • FIG. 2 shows a pouring part in perspective, the broad sides of which open conically up to an inner width K against the direction of flow.
  • a square with the edge length K suffices in the middle, onto which the end face 12 of the tubular pouring part 11 can be placed or can even be pushed through an opening of a corresponding size.
  • the end wall 27 can be designed to converge conically to the edge of the broad sides 26.
  • the open cross-sectional area of the pouring part A E is also shown in an open section in FIG. 2, which is calculated from the distance between the broad sides a multiplied by the distance between the narrow sides b.
  • the cross-sectional area A R of the pouring part 11 is obtained in relation to the rectangular free cross-sectional area A E of the pouring part 21 like A R / A E ⁇ 1.7.
  • the length of the transition part I is shown in the figure and indeed behaves this to the distance of the broad sides a like I / A ⁇ 1/4.
  • the total length of the immersion nozzle consisting of the pouring part 11 and the Pouring part 21 is marked with L.
  • FIG. 3 shows a sketch of a diving spout, in which the pouring part is on the head side Shape of a roof is formed, the head end in the middle in slots 14 the pouring part 11 is fitted with its corresponding area 24.
  • the head 25 of the pouring part 21 has an end wall 27 which from the pouring part in The direction of conveyance opens roof-shaped up to the edge of the broad sides.
  • the slot 14 of the pouring part 11 or the part 24 of the slot corresponding to the slot 14 Pouring part 21 has a length of 1.
  • FIG. 4 shows the mouth region 13 of the pouring part 11 in detail.
  • Top view of the slot 14 can be seen in the pouring part into which the corresponding part 24 is fitted.
  • a spring 29 is provided which in a groove 19 of the Pouring part 11 is fitted.
  • the arrangement of tongue and groove is a horizontal pushing together of parts 11 and 21 possible, but in operation a Preventing the pouring part 21 from falling out of the slot 14 of the pouring part 11.
  • FIG. 5 shows an immersion nozzle with a pouring part 21 which is attached to the pouring vessel 41 completely independently of the pouring part 11.
  • the pouring part 11 which is arranged directly below the outlet opening 43 of the pouring vessel 41, is surrounded by an insert 28 in the pouring space G E of the pouring part.
  • the insert 28 has a shape which, in a suitable manner, guides the melt stream leaving the tubular casting 11 with little swirling.
  • the pouring part 11 has in the mouth area 13 impact elements 16, which are in the right part of the picture for example, tapered in the direction of flow by inserts 18 are configured on, which complete the projecting part of the pouring part 11.
  • This configuration makes it possible to use the shortest possible route after leaving the outlet opening 43 has a round cross-sectional area metal melt the shortest possible way to force a metal stream into a rectangular one Cross-sectional area has a large narrow / wide aspect ratio.
