Definitions

  • the invention relates to continuous casting and relates more particularly to the continuous casting in a curve ⁇ d discharge path of steel lbillets in which the descending billet is deflected to the horizon-tal plane and wherein during the normal cas-ting operation the liquid sump projects with its leadin-g poin-t and a portion to the rear thereof to a minor and major extentinto the horizontal plane.
  • the aforesaidV mass head effect operates in a core condensing manner from the beginning until the end of the casting operation, and remains effective for a while even after the teeming of molten steel into the mold has been halted, -namely as long as liquid steel descends alone in the casting direction into the leading point of the sump which is formed by the converging solidification fronts.
  • the single view is a schematic side elevational view, partly in section, of a billet during its curved-discharge path after the mold.
  • Example 1 In casting a billet of an edge length of 200 x 200 mm. the casting speed VN is assumed to be 900 mm./rnin. Under these conditions-at constant cooling-the length of the liquid sump SN is 8 m.
  • the distance of the liquid sump of 8 m. is situated for a stretch of about 6 1n. in the curved portion of the billet and the remainder which equals about 2 m. is disposed in the horizontal plane.
  • the length of the sump should be diminished for more than 2 m.for instance, for 2.5 m.-to about 5.5 m.
  • the casting speed must be reduced to 620 mm./min. and continuing at a reduced Withdrawal speed sufficiently long so that the leading snmp point will recede in the horizontal towards the casting head in the casting curve and will coincide with the end head before the horizontal is reached.
  • the steps comprising, reducing the casting speed at least shortly'before the end of the steel delivery to the mold to reduce the length of the sump and contin-ning 'withdrawal at a reduced casting speed so that thereafter the leading point of the sump is maintained above the horizontal.
