Abstract (en)
[origin: WO03070399A1] The invention relates to a method and a continuous casting device for the direct shaping of a metal strand, in particular a steel cast strand (1) of any format (1d). According to said method, the cast strand (1) is only cooled by a liquid coolant (4) in longitudinal sections (6), where the interior of the cast strand (1) remains liquefied and the temperature of the cast strand (1) in a transition zone (7) upstream of, in and/or downstream of a bending and straightening unit (8) is evened out by an insulation of the exterior surface (1 b), essentially without the use of a liquid coolant (4), and by progressive thermal radiation. The cast strand (1) is shaped in a dynamically variable reduction section (9) as a result of the compressive strength that is measured on individual shaping rolls (10) or roll segments (11), depending on the compressive force that can be locally applied.
