Definitions

  • the invention relates to a continuous casting mold, in particular for casting billets or blooms, the pour tube from a mold housing with Gap distance is surrounded, in which a coolant flow can be fed and again is dissipatable.
  • the liquid steel solidifies in the continuous casting mold from outside to inside during the casting process.
  • the heat dissipation in the continuous casting mold can be regulated via locally coordinated water speeds. A maximum of heat must be dissipated in the meniscus of the mold bath level, while a correspondingly smaller amount of heat must be dissipated at the outlet of the continuous casting mold.
  • DE-OS 14 83 556 provides a cooling zone division to the mold height, each of the superimposed cooling zones has its own access and Discharge line is allocated.
  • the invention has for its object the speed of the cooling medium in the cooling channel of the cooling jacket of a continuous casting mold on the geometry of the To control the coolant jacket.
  • the object is achieved according to the invention in that the cooling medium gap is so wide across the mold height that in the upper Mold area of the cooling medium gap is narrow, corresponding to a high cooling medium speed, and is relatively wide in the lower mold area, accordingly a relatively lower cooling medium speed.
  • This allows through this geometric design of the cooling media channels regulates the water speeds and thus the heat dissipation can be achieved.
  • At least the vertical contour corresponds to the outer cooling medium gap wall a negative form of the solidification line in the casting strand from above runs down. This negative form leads to low cooling medium speeds too high in the lower mold area and due to the narrow gap Coolant speeds in the upper mold area.
  • a further improvement of the geometrical cooling gap shapes results from that the cooling medium gap is additionally enlarged in corner areas. There the corners of the casting strand compared to the surfaces less heat dissipation the cooling medium speed can be reduced somewhat here.
  • cooling medium gap over the broadside of the mold and / or the long sides of the mold are of different widths, the narrow gap is provided in the center of the page. This will be in the middle of the page due to the narrow gaps, a higher cooling medium speed and a lower speed at the corners due to the bulges achieved.
  • the pouring tube is cylindrical and the mold housing (the water guiding jacket) has the vertical contour.
  • a favorable flow with a small flow resistance also arises from that the corner areas of a horizontal contour each bulging oval are trained.
  • the continuous casting mold is used in particular for casting billet or blooms and is provided with a pouring tube 1 and a mold housing 2, that forms a water jacket 2a.
  • the mold housing 2 lies with Gap distance 3 around the pouring tube 1.
  • the cooling medium 4, as usual, water or Water with additives is in the cooling medium gap 5 at the mold level 6 in fed lower mold area 6b and heated while rising in the upper mold area 6a again in the direction of the arrow after heat has been absorbed dissipated.
  • the cooling medium gap 5 is of different widths over the mold height 6, in that the cooling medium gap 5 is narrow in the upper mold region 6a, accordingly a high cooling medium speed, and in the lower mold area 6b is relatively wide, corresponding to a relatively lower cooling medium speed.
  • the flow rate of the cooling medium 4 depends according to the negative form of the solidification line in the casting strand, at least according to the the vertical contour 7 of the outer cooling medium gap wall 5a is fixed is (Fig. 1).
  • the cooling medium gap is in accordance with the section A-A in the horizontal (FIG. 2) 5 additionally enlarged in the corner areas 8.
  • the cooling medium gap 5 is based on the basic idea of the mold wide side 9 and / or the long side of the mold 10 of different widths, with the narrow gap 11 in the center of the page 12 lies.
  • the production of the pouring tube 1 is simple and can be carried out very precisely be, since the pouring tube 1 is cylindrical in and of itself Chill mold housing 2 has the vertical contour 7 (FIG. 1). The same property results in a horizontal section (FIG. 2) if the corner regions 8 are horizontal Contour 13 are each bulged oval.
