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.
