Definitions

  • This invention relates to a'method and apparatus for continuous casting metal wherein a tundish is employed to perform continuous casting operation by directly connecting the tundish with moulds without the necessity of utilizing a nozzle, thus enabling continuous operation over a long period of time without being damaged by the molten metal.
  • a mould is connected to the tundish through a nozzle secured thereto so as to pour the molten metal, steel for example, into the mould.
  • nozzle There are two types of nozzle, namely-an open nozzle and an immersed nozzle.
  • the latter type of nozzle is advantageous in that the RECIPROCATING stream of the molten steel poured into the mould through the nozzle is not exposed to the atmosphere and hence is not oxidized; It is also well known to incorporate so-called powder into the mould toprevent oxidation of the molten steel in the mould and to prevent cooling thereof.
  • a method of casting molten metal into a mould through an opening of a tundish characterized by directly coupling the mould to the opening through a refractory coupling piece thus pouring the molten metal into the mould from the opening through the coupling piece while the mould is oscillated vertically together with the tundish.
  • apparatus for casting molten metal into a mould through an opening of a tundish characterized by comprising a refractory coupling piece secured to the tundish around the opening, the lower surface of the coupling piece being directly connected to the mould, reinforcing members secured to the side surfaces of the tundish to reinforce the connection between the same and the mould, and an oscillating mechanism connected to the reinforcing members to oscillate in the vertical direction the tundish together with the mould.
  • FIG. 1 shows a vertical section of the moulding apparatus embodying this invention
  • FIG. 2 shows a longitudinal section taken along a line II II in FIG. 1;
  • FIG. 3 shows a cross-sectionalview taken along a' line III III in FIG. 1.
  • the moulding apparatus illustrated in the accompanying drawing comprises a tundish 1 including a steel casing 2 lined with a refractory lining consisting of a permanent brick lining 3 and a brick lining or working lining 4 which is contacted by molten steel.
  • the working lining 4 may be formed by stamping of a powdered refractory material.
  • An opening 5 is formed at the bottom of the tundish 1 to pour the molten steel and a coupling piece 6 of refractory material is connected to the linings 3 and 4 around the periphery of opening 5 by means of a suitable mortar such as an air set mortar.
  • the molten metal in the tundish l is poured directly into the mould 7 through opening 5 without the intervention of a nozzle or the like.
  • the novel casting apparatus is suitable for the continuous casting operation of a large quantity of molten steel.
  • the molten metal is directly poured into the mould, it is possible to prevent oxidation of the molten metal by the atmosphere, while the molten metal flows from the tundish into the mould. It is also possible to improve the quality of the casting without the necessity of considering the fluidity of the metal on the upper surface of the mould.
  • reinforcing means (9) secured to the side surfaces of said tundish (l) and extending around a substantial portion of the interconnection of said mould (7) to said tundish (1) via said refractory coupling piece (6) to reinforce the connection between said tundish (l) and said mould (7);
  • an oscillating mechanism (10) connected to said reinforcing means (9) to oscillate said unitary assembly in the vertical direction.
