Abstract
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 () 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.
