Definitions

  • the invention relates to a mold for the continuous casting of metals, preferably steel, with a multi-conical mold cavity which is open on two opposite sides, the mold cavity cross section being larger at the end on the pouring side than at the end on the strand exit side.
  • a mold is known from US-A-4 207 941.
  • the invention has for its object to provide a mold of the type mentioned, with which on the one hand a higher casting performance and on the other hand a better strand quality can be achieved. At the same time, the heat dissipation of the partially molten strand is to be optimized in order to increase the service life of the mold.
  • the first area which has a partial length of 320 mm in the casting direction, has a taper of 2.4% / m. For the subsequent partial length of 480 mm, a taper of 1% / m was chosen.
  • the cooling-optimized region 2 with triangularly shaped recesses 3 in the cooling-side surface of the mold 1 extends to a partial length of approximately 310 mm, which begins 60 mm below the pouring side.
  • the pouring side of the mold 1 is indicated by the arrow 4.
  • the center distance of the recesses 3, which are triangular in cross section, is 8 mm in the casting direction, the individual recesses 3 having a width of 4 mm.
  • the maximum extent of the depressions 3 perpendicular to the surface is 1.2 mm.
  • the respective geometrical features of the cooling-optimized area 2 have been determined by evaluating casting tests.
  • FIG. 2 Another embodiment is shown in Figure 2.
  • the tubular mold 1, which is also provided for the continuous casting of square cross sections, has a cooling-optimized region 2 which consists of a multiplicity of circular depressions 3.
  • the overall trapezoidal area 2 extends over a partial length of 250 mm, where it tapers in the casting direction by approximately 30%.
  • Arrow 4 denotes the pouring side and arrow 5 denotes the end on the strand exit side.
