Definitions

  • the object is further achieved according to the invention by means of guidance and cooling in that the casting strand can be subjected to a targeted temperature control in the individual support segments, secondary cooling adapted to the extrusion profile being usable from support segment to support segment, and that to zero Support segment following support segments are designed so open that excess spray water can be derived from the casting strand cross section in a plurality of directions.
  • a targeted temperature control in the individual support segments secondary cooling adapted to the extrusion profile being usable from support segment to support segment, and that to zero Support segment following support segments are designed so open that excess spray water can be derived from the casting strand cross section in a plurality of directions.
  • the strand shell thicknesses are specified in mm at a distance of 2 m to 2 m.
  • the length L denotes the total length of the system from the continuous casting mold 3 to the pulling-out machine 9.
  • the radii R1, R2 and R3 define the arc of the strand course.
  • the true-to-shape casting strand 1 produced in the continuous casting mold 3 enters the zero support segment 4 (FIG. 2B), in which the casting strand 1 by means on the long side 13 in the long side center region 16 arranged support rollers 17 and support rollers 18 arranged on the transverse sides 14 is supported.
  • the cast strand profile corner regions 19 are not cooled, but are supported by means of tip rollers 20.
  • the spray water jets 8 each form an angle that opens in the direction of flow with respect to the strand that is still in the liquid or viscous region and its strand width or strand thickness.

Abstract

L'invention concerne un procédé et un système de guidage pour soutenir, guider et refroidir des barres de coulée en acier (1), notamment des ébauches de profilés (2) pour des poutres, qui sont refroidies par des projections d'eau (29) avant d'être évacuées. Ce procédé et ce système servent à éviter la formation de fissures, notamment de fissures superficielles, dans la structure des barres, grâce à l'adaptation des conditions de refroidissement de la surface des barres lors du refroidissement secondaire. Ils servent également à éviter un surrefroidissement de la croûte de la barre. Pour éviter une solidification indésirable sur les arêtes supérieures des ailes des profilés ou dans d'autres zones de la section transversale, le refroidissement et le soutien du format de l'ébauche de poutre sont adaptés aux zones de solidification de sorte qu'ils s'effectuent uniquement dans les zones où se forme un cratère liquide. A cet effet, la barre de coulée (1) est refroidie sur les côtés longitudinaux et transversaux (13 ; 14) de sa section transversale (1a) par un pilotage ciblé de la température dans des segments de soutien supérieurs (5, 6, 7) au moyen de jets d'eau (8) présentant une largeur au moins équivalente à la longueur des rouleaux de soutien. La barre de coulée est de moins en moins soutenue, de manière analogue à la longueur du trajet de la barre et à l'état de refroidissement dans des zones centrales (15) de la section transversale (1a) de la barre, sur les côtés transversaux (14) de la section transversale (1a) de la barre, et elle est refroidie uniquement au moyen de jets d'eau (8) dirigés sur les zones centrales (15).
