METHOD AND DEVICE FOR THE CONTINUOUS CASTING AND DIRECT SHAPING OF A METAL STRAND, IN PARTICULAR A STEEL CAST STRAND

摘要

The invention relates to a method and a continuous casting device for thedirect shaping of a metal strand, in particular a steel cast strand (1) of anyformat (1d). According to said method, the cast strand (1) is only cooled by aliquid coolant (4) in longitudinal sections (6), where the interior of thecast 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 andstraightening 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 progressivethermal radiation. The cast strand (1) is shaped in a dynamically variablereduction section (9) as a result of the compressive strength that is measuredon individual shaping rolls (10) or roll segments (11), depending on thecompressive force that can be locally applied.
