Method and device for the continuous casting and direct deformation of a metal strand, especially a cast steel strand

摘要

A method for the continuous casting and direct deformation of a metal strand, especially a cast steel strand, includes guiding the metal strand in a curved strand glide after the continuous casting mold, subjecting the strand to a secondary cooling with a liquid coolant, and preparing the strand in an automatically controlled way for the deformation pass at a uniform temperature field in the strand cross-section, such that the cast strand is cooled with a liquid coolant only in the longitudinal sections in which the cast strand is liquid in the cross-section. The temperature of the cast strand is equalized in a transition zone before, in, and/or after a bending-straightening unit by insulation of the exterior surface that is radiating heat, without the use of the liquid coolant, and is further equalized by heat radiation in zones until the temperature field consists of elliptical, horizontally oriented isotherms. The cast strand is deformed on a dynamically variable soft production line on the basis of the compressive strength measured by individual deforming rolls or roll segments, depending on the compressive force that can be locally applied.
