Definitions

  • the invention relates to a continuous casting installation for the optional casting of a strand with a slab cross section or at least two strands of smaller cross section, with a plate mold which is provided with a water box carrying the narrow and broad side walls, further narrow side walls being provided for casting at least two strands between the narrow side walls.
  • a disadvantage of this construction is the space required for the intermediate wall fastened on the broad side walls, by which the usable cross sections of the mold are reduced.
  • Another disadvantage is the fact that the adjustable fastening of the plates to the fixed intermediate wall requires components that protrude above and below the upper or lower edge of the mold, so that on the one hand the upper cover of the mold has to be provided at a greater distance than usual, whereby the visibility into the mold is deteriorated, and on the other hand casters cannot connect directly to the lower end of the mold, which creates the risk of bulging of the strand at high casting rates.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to provide a continuous casting installation of the type described in the introduction, in which the cross-sectional area available for the slab cross-sectional format is used optimally when casting several strands of smaller cross-sectional format, the visibility being reduced to that The mold and the strand guide immediately below the mold should not be deteriorated compared to a mold for casting strands with a slab cross-sectional format.
  • This object is achieved in that for casting at least two strands of smaller cross-section through the copper plates of the broad side walls between the end narrow side walls are formed at least shared a recess in the strand longitudinal direction, and that the other narrow side partitions are inserted into the recesses of the narrow side walls opposite each other, which are within the recesses respectively to the support structures of the K upferplatten the wide side walls supported.
  • the narrow side partitions in the lower end region are expediently supported in each case by means of articulation bolts which protrude into the narrow side intermediate walls and are arranged in the region of the recesses and fastened to the supporting structure, and in their upper end region by means of tabs of the narrow side intermediate walls which project laterally into the recesses penetrating set screws fixed to the support structures.
  • the narrow and broad sides as well as the narrow side partitions with their support structures of the mold for at least two strands of smaller cross-section form a unit that can be removed and installed from the system, with regard to its external dimensions and connection dimensions a one into the system and corresponds removable structural unit for a strand with B ram cross-sectional format.
  • the narrow and broad sides as well as the narrow side partitions with their support structures of the mold for at least two strands of smaller cross-section form a unit that can be removed and installed from the system, with regard to its external dimensions and connection dimensions a one into the system and corresponds removable structural unit for a strand with B ram cross-sectional format.
  • the water tank when converting the continuous casting system during this operation, ie in other words that the water box forms part of the structural unit. This makes the changeover particularly easy and quick to do because you only need the water box - together with the broad and narrow side walls supported on it - must be lifted off the lifting table by means of a crane or inserted into the lifting table.
  • a particularly robust construction is characterized in that the supporting structures are each formed in one piece for the copper plates of the broad side walls, which are aligned on one side, and extend over the entire length of the aligned copper plates.
  • the support structures of the broad side walls are expediently divided into two mutually independent support structure parts by means of the recess, which makes it possible, in the event of failure of a mold part for one of the strands, to remove this part of the mold independently of the other parts and to continue casting the other strands.
  • a particularly expedient, space-saving arrangement of the casters arranged below the mold converted for several strands is characterized in that, on the underside of the mold provided for at least two strands of smaller cross section, casters for the broad sides of the strands are arranged in height between the casters for the narrow sides of the strands below the narrow side partitions arranged, one-piece castor holders are rotatably mounted.
  • a particularly simple embodiment is characterized in that the narrow intermediate walls are inserted in their upper region by means of strips which laterally project into the recesses in grooves of the support structures which correspond to the strips.
  • FIG. 1 showing a partially sectioned plan view of a mold
  • FIG. 2 a section along line II-II of FIG. 1.
  • FIG. 5 shows a further embodiment in a representation analogous to FIG. 1, but without a water tank.
  • Fig. 6 shows a view of a castor holder along the line VI-VI of Fig. 2.
  • a water box 1 is placed on a lifting table of a mold, not shown.
  • This water box 1 is adapted in terms of its longitudinal extent to the largest strand cross-sectional format that can be cast on the continuous casting installation.
  • special support structures 2, 3 for broad side walls 4, 5 are used in the water box 1, a support structure 2 being supported on the water box 1 and the second, opposite support structure 3 on the first support structure by means of a Bolt 6 is fixed and can be tensioned against the first support structure 2.
  • Both support structures 2, 3 each carry two copper plates 7 forming the broad side walls 4, 5, the copper plates 7 each arranged on a support structure 2, 3 being separated from one another by a recess 8.
  • the recesses 8 continue in part in the support structures 2, 3.
  • adjustable narrow side walls 10 are clamped in the usual way by means of actuators 9.
  • each narrow side intermediate wall 11 is supported in its lower end region by means of hinge bolts 12 arranged in the area of the recesses 8 and fastened to the support structures 2, 3, which project into U-shaped recesses 13 of each narrow side intermediate wall 11 that are open towards the bottom.
  • the narrow side intermediate walls 11 have tabs 14 which project laterally into the recesses 8 and which are fixed to the respective supporting structures 13, 3 by means of set screws 15 and counter screws 16.
  • the supply of cooling water to the narrow side partitions takes place by means of plug-in tubes 17 passing through the water box, each of which projects into the interior of the narrow side partitions 11 with one end.
  • the plug-in tubes 17 have flexible intermediate pieces 18.
  • the mold does not have any fastening elements for the narrow side intermediate walls 11 arranged above the upper edges 19 of the broad side walls 4, 5 and below the lower edges 20 of the broad sides, which makes it possible, on the one hand, to have a mold cover directly above the mold to provide, and on the other hand it is possible to provide casters immediately below the mold.
  • the castor holder 23 which receives the castors 21, 22 is formed in one piece (FIG. 6) and is fastened to the support structures 2, 3 by means of screws 24 which extend up to the top thereof.
  • the narrow and broad side walls 4, 5, 10, 11, together with the surrounding water tank 1, result in a unit that can be installed and removed from the mold and that, with regard to its external dimensions and connection dimensions - for the coolant supply lines - is a unit that can be installed and removed from the mold for a strand with a slab cross-sectional format.
  • the additional narrow intermediate walls are provided in their upper region with strips 25 which laterally protrude into the recesses 8, the strips 25 being inserted into corresponding grooves 26 of the support structures 2, 3.
  • the inclination of the additional narrow side partitions 11 cannot be adjusted.
  • the narrow side partitions are supported at their lower end region, as is illustrated in FIGS. 1 and 2.
  • the recesses 8 are designed so large that the support structures 2, 3 of each of the broad side walls 4, 5 are divided into two. Each part 2 ', 2 ", 3', 3" of the support structures 2, 3 is supported separately on the water tank 1. This has the advantage that in the event of the failure of a side wall 4, 5, 10, 11 of a mold cavity 27 or 28 in the other mold cavity, casting can continue and the non-intact part of the mold during this can be removed and repaired.
  • the invention is not limited to the embodiment shown in the drawing, but can be modified in various ways.
