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