Definitions

  • the invention relates to a horizontal continuous casting plant for the continuous casting of a strand with a slab cross-sectional format, in particular a steel strand, with a storage container for the molten metal and a continuous mold connected to it in line, and with a horizontal strand guide supporting the strand emerging from the mold.
  • Another disadvantage is that the cooling of the strand on its top and bottom cannot be carried out uniformly, since standing or flowing water on the top of the strand creates unequal conditions.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to create a horizontal continuous caster of the type mentioned in which the slab cross-sectional format after leaving the mold despite a small one ferrostatic pressure is maintained. Furthermore, uniform cooling of the strand is to be achieved with simple means.
  • the strand guide is preferably designed as a roller table which has rollers with vertically aligned axes that support the strand on its broad sides.
  • the inlet side of the mold is formed by a fixed refractory plate which extends transversely to the longitudinal axis of the mold and projects into the cavity formed by the mold narrow and broad side walls with little play. wherein the narrow and wide side walls of the mold on a reciprocating these walls in the horizontal direction Oscillating drive are connected.
  • the refractory plate has, on its part projecting into the cavity of the mold, a peripheral circumferential groove into which an inert gas supply line opens, the circumferential groove expediently including porous refractory material is filled.
  • the side of the refractory plate facing the mold cavity is provided near its periphery with flushing stones made of porous refractory material, which flushing stones are connected to a line which supplies inert gas.
  • FIG. 1 a section through a horizontal continuous casting installation according to the invention in a schematic illustration
  • FIG. 2 a detail of FIG. 1 on an enlarged scale
  • FIG. 3 a view in the direction of arrow III demonstrate.
  • FIG. 4 illustrates a second embodiment of a horizontal continuous casting installation according to the invention in an illustration analogous to FIG. 1.
  • a storage container 1 which can be designed as a distribution vessel or as a pan (for single casting), is filled with molten steel 2.
  • a horizontal outflow opening 4 is arranged near its bottom 3.
  • the steel melt 2 passes through this outflow opening to a continuous mold 5 which is advantageously designed as a plate mold, a plate or rotary valve 6 being provided between the continuous mold 5 and the outflow opening 4.
  • a continuous mold 5 which is advantageously designed as a plate mold, a plate or rotary valve 6 being provided between the continuous mold 5 and the outflow opening 4.
  • the slide 6 and the Chill mold 5 are made of fireproof material 7.
  • the mold 5 has a stationary plate 8, which is formed from refractory material.
  • This refractory plate extends transversely to the longitudinal axis 9 of the mold 5 and forms an end of the mold cavity 12 formed by the narrow 10 and broad side walls 11 of the mold.
  • the refractory plate 8 projects partially into the cavity 12 of the mold and is rigid connected to the pouring tube 7 arranged between the slide 6 and the mold 5.
  • the mold 5 itself is arranged upright, so that its wide side walls 11 are vertical and the narrow side walls 10 are horizontal. All mold side walls 10, 11 are connected to an oscillating drive, not shown, so that they oscillate in the horizontal direction parallel to the axis 9. Between the refractory plate 8 and the mold side walls 10, 11 there is a gap 13 surrounding the refractory plate 8 peripherally, through which an inert gas flows out to seal the refractory plate 8 with respect to the mold side walls 10, 11 and is supplied via the refractory plate 8 .
  • the refractory plate 8 As shown in FIGS. 2 and 3, has a peripherally circumferential groove 14 on its part projecting into the cavity 12 of the mold, which is filled with porous refractory material 15 . At several points, the inert gas supply bores 16 of the plate 8 open into this groove.
  • flushing stones 17 are provided near the circumference of the refractory plate 8 on the side facing the mold cavity 12, which are also made of porous refractory material.
  • the inert gas supplying bores 16 also open into these flushing stones 17.
  • a distributor line 18 is connected to the bores 16.
  • the strand 19 emerging from the continuous mold is supported by means of a strand guide 20 which is preferably designed as a roller table.
  • This roller table 20 has the strand 19 on its broad sides supporting rollers 21 with vertically aligned axes 22.
  • the rollers 23 supporting the narrow sides are arranged with a horizontal axis 24.
  • the spray pattern 25 of the cooling nozzle arranged on the side of the broad sides of the strand 19. 26 is also illustrated in FIG. 1.
  • the strand 19 Due to the upright cross-section, the strand 19 has a higher section modulus and the ferrostatic pressure present in the strand due to the liquid sump prevents the broad sides of the strand from sinking in.
  • a somewhat different solidification structure in the strand, which results from the upright strand 19, can be avoided by using electromagnetic stirring coils of an inductive or conductive type.
  • both broad sides of the strand can be cooled uniformly.
  • the thermals are the same on both broad sides and no standing or flowing water can form on one broad side, as with horizontal broad sides.
  • the refractory plate 8 is arranged directly on the storage container 1 without the interposition of a slide.
  • the refractory plate 8 can be moved laterally.
  • a copper plate is inserted instead of the refractory plate 8 in order to obtain a perfect lid formation for the strand 19.
  • a displaceable intermediate plate 27 is provided between the refractory plate 8 and the storage container 1 on the side wall 10 of the mold 5 which forms the upper narrow side of the strand and extends to the refractory plate 8.
  • the invention is not limited to the exemplary embodiment shown, but it can be modified in various ways.
