Patent ID: 7121323

Claim:
Method for the continuous casting and direct deformation of a metal strand, especially a cast steel strand ( 1 ), which has a rectangular format or the format of a bloom, preliminary section, billet, or round, is guided in a curved strand guide ( 3 ) after the continuous casting mold ( 2 ), subjected to secondary cooling with a liquid coolant ( 4 ), and prepared in an automatically controlled way for the deformation pass at a uniform temperature field ( 5 ) in the strand cross section ( 1 a ), such that the cast strand ( 1 ) is cooled with a liquid coolant ( 4 ) only in the longitudinal sections ( 6 ) in which the cast strand ( 1 ) is liquid in the cross section ( 1 a ), wherein the temperature of the cast strand ( 1 ) is equalized in a transition zone ( 7 ) before, in, and/or after a bending-straightening unit ( 8 ) by insulation of the exterior surface ( 1 b ) that is radiating heat, without the use of a liquid coolant ( 4 ), and further equalized by heat radiation in zones in such a manner that colder corner regions ( 1 f ) are cooled and supported less than other cross-sectional parts, which are connected with the still hot core region ( 1 c ), until the temperature field ( 5 ) consists of elliptical, horizontally oriented isotherms ( 12 ), and that the cast strand ( 1 ) is deformed on a dynamically variable soft reduction line ( 9 ) on the basis of the compressive strength measured by individual deforming rolls ( 10 ) or roll segments ( 11 ), depending on the compressive force that can be locally applied.
