СПОСОБ И УСТРОЙСТВО ДЛЯ НЕПРЕРЫВНОЙ РАЗЛИВКИ НЕПОСРЕДСТВЕННЫМ ОБЖАТИЕМ МЕТАЛЛИЧЕСКОЙ ЗАГОТОВКИ, В ЧАСТНОСТИ, СТАЛЬНОЙ ЗАГОТОВКИ

摘要

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 ( 1 d). 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.
