Abstract

A method for casting and rolling preliminary sections, especially H-sections, and a device for the support, guidance and deformation of a metal strand, especially a steel cast strand (1), in a continuous casting installation for preliminary sections with soft reduction (9), wherein roll carriers (2) are arranged below the continuous casting mold opposite each other on each side of the cast strand (1a, 1b), the rolls of said carriers being in transport and/or deformation connection with said cast strand, and wherein to avoid segregation and porosity, the preliminary section is precast in the continuous casting mould with a bulge (6a) on the flanges (7) on the surface (6b) of the web of said preliminary section, and the bulges (6a) of the flange (7) and the web of the preliminary section (6) are rolled flat in the soft reduction area (9) in such a way that the outer surfaces of the flange (7a) and the web surfaces of the preliminary section (6b) are largely plane.
