Definitions

  • Known equipment includes means for charging a mold through lateral openings below the surface level of the molten material and deflector plates are disposed in front of the openings.
  • Equipment of this type is, for example, disclosed in "Handbuch des Stranggiessens" (Handbook of Continuous Casting) by Herrmann, 1958, p. 328, FIG. 1,107.
  • the problem solved by the present invention is to provide deflecting plates in front of exit ports of a submerged distributor but at such an orientation that a particularly oriented flow is generated in the mold which flow is metered in accordance with casting rate and capacity, whereby, on one hand, the surface level remains liquidous, and, on the other hand, a favorable distribution of nonmetallic inclusions is produced as it is particularly necessary for continuous casting of steel.
  • a pipe or the like is also used for charging the mold.
  • deflector plates in front of laterally oriented, submerged ports of the pipe through which the mold is charged with molten steel, the plates being oriented at an angle to be inclined in down direction and having particularly an angle of to 45 relative to the direction of casting.
  • the distance of the upper (submerged) edge of the deflector plate or plates from the pipe amounts to about 5 to 40 millimeters.
  • the inclination of these plates depends upon the quality of steel, capacity and rate of casting and upon the temperature of the molten material. Generally, a higher capacity, other parameters being similar, requires a larger angle and also smaller spacing between upper deflector edge and pipe.
  • FIG. 1 illustrates a longitudinal section through the upper portion of ap aratus for continuous casting improved in accordance with the preferred embodiment of the present invention
  • FIG. 2 illustrates a section view taken along line A-A in FIG. 1.
  • FIG. 1 a continuous casting mold 1 charged from a distributor ladle 2.
  • the head 12 of the product to be cast is still liquidous in the mold, and the casting product (billet, slab etc.) is withdrawn from a bottom opening of mold l a solidified shell 13 is formed around the still liquidous core, slag 4 accumulates at the surface level of the molten steel in the mold.
  • a stream 10 of steel pours from ladle 2 into the interior chamber 11 of a particular charge pipe 3 which is suspended from the bottom of distributor ladle 2 and dips into the head 12 liquid steel in mold 1. Exit openings or ports 5 of pipe 3 are submerged, i.e., they are located underneath the surface level of the molten steel in the mold. The bottom of pipe 3 is closed.
  • Deflector plates 6 are provided in front of the oppositely laterally oriented ports 5.
  • the deflector plates 6 are disposed at an angle a relative to the vertical, or being about 10 to 45.
  • deflector plates 6 are submerged and they are respectively spaced from pipe 3 by about 5 to 46 millimetets.
  • steel 10 pours continuously from distribution ladle 2 into pipe 3 and exits through ports 5.
  • a portion of the outflow is branched off to flow in up direction over and around the submerged edges 6a of deflection plate 6.
  • the relative amount of the up flow is determined by the angle a of deflection plates 6 as well as by the escape openings between upper edges 6a of deflection plates 6 and pipe 3.
  • the bulk of the steel flowing from port 5 is deflected in down direction and flows toward and into the continuous cast ingot as extracted from mold 1 in the same direction.
  • Apparatus for distributing molten steel in a mold used for continuous casting, the casting product being extracted and withdrawn from the mold in a downwardly direction comprismg:
  • a closed end pipe having lateral ports adapted to be submerged in the molten steel in the mold, the molten steel being charged into the mold through the pipe and through the submerged ports;
  • submerged deflector plates mounted in front of the ports in the mold, the plates each having an outwardly inclined angle of 10 to 45 relative to the direction of casting so as to deflect the bulk of the molten steel leaving the ports into a downwardly direction, the plates having upper edges respectively spaced from the pipe and adapted to be submerged so that part of the :molten steel leaving the ports flows up toward the surface level of molten steel as sustained in the mold.
  • each deflector plate having distance from the pipe of 5 to 40 millimeters.
