Abstract: A process for extruding liquid metals, especially steel (1) and soft reducing the length over the tip region comprises controlling the temperature to the solidification point before the tip. Isotherms (9) in the temperature profile are maintained at a constant value over the length and thickness.

Abstract: A device for continuous casting and direct deformation of a metal strand, with a strand guide which is curved after the continuous casting mold in the direction of strand travel, a spray device for liquid coolant, a bending-straightening unit, and an automatic control system for a uniform temperature field in the strand cross section. 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 curved strand guide with the spray device for liquid coolant is followed by a dry zone, which operates without liquid coolant and serves as insulation against the elimination of radiant heat and systematically surrounds the cast strand. A reduction line is provided, which includes individual, hydraulically adjustable deforming rolls or several hydraulically adjustable roll segments and precedes, coincides with, or follows the region of the bending-straightening unit.

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 (1) of any format (1d). 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 (1b), 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.
