Definitions

  • Fig. 1d is the time in continuous casting shown, in which the supply of molten steel was just stopped in the mold.
  • the drawing speed v corresponds to the second drawing speed v 2 of 0.36 m / min. This pull-out speed of the strand 1 is maintained until the end of the pull-out operation (see Fig. 3a ).
  • the Fig. 7b shows an alternative to Fig. 7a , wherein the degree of coverage of the insulating flaps 9a of the strand at the strand end 1c is higher than at the strand beginning. This also increases the heat transfer coefficient U of the heat insulation 9 in the casting direction G.
  • FIG. 10 schematically a head insulation 18 of a strand 1 is shown.
  • the head insulation has a heat insulation 9 for the strand end 1c of the strand 1, so that the strand end 1c remains liquid longer.
  • an exothermic powder 19 on the liquid strand end 1c be abandoned, which additionally heats the strand 1.
