Abstract:
1. Device for continuous casting and direct deformation of a metal strand, which has a rectangular format or a format of a bloom, preliminary section, billet, or round, with a strand guide ( 3 ) which is curved after continuous casting mold ( 2 ) in the direction of strand travel ( 23 ), a spray device ( 4 a ) for liquid coolant ( 4 ), a bending-straightening unit ( 8 ), and an automatic control system for a uniform temperature field ( 5 ) in a thickness cross section ( 1 a ) of the strand, 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 curved strand guide ( 3 ) with the spray device ( 4 a ) for liquid coolant ( 4 ) is followed by a dry zone ( 24 ), which operates without liquid coolant ( 4 ) and serves as insulation ( 25 ) against the elimination of radiant heat and systematically surrounds the cast strand ( 1 ), and that a reduction line ( 9 ) is provided, which consists of several hydraulically adjustable roll segments ( 11 ) and precedes, coincides with, or follows the region of the bending-straightening unit ( 8 ), wherein a detection apparatus is provided for determining the position of the tip of a liquid crater, wherein roll segments ( 11 ) of the reduction line are displaceably arranged on a common base plate ( 26 ) in the direction of strand travel ( 23 ) next to one or more stationary bending-straightening units ( 8 ) and are displaceable in the direction of strand travel ( 23 ) or in the opposite direction, wherein the control system displaces the base plate with the roll segments back and forth according to the determined position of the tip of the liquid crater.
