Abstract: A method and device for continuous casting and subsequent deformation of a cast strand (1) of steel, especially a cast strand (1) of an ingot shape (2) or a preliminary section shape, in which the secondary cooling (4) and the strand support (11) are matched to the cooling state of the cast strand cross section (1a) with respect to steel quality and in which the segregations and porosity are of significance with respect to further processing and the end uses of the product and require steps for improvement of the 10 internal quality and for the surface qualities, in which the secondary cooling (4) in its geometrical configuration is analogously matched to the solidification profile (5) of the cast strand (1) along the respective distance travelled (6) of the cast strand and in which the cast strand support (11) likewise is analogously reduced in dependence upon the solidification profile (5) of the cast strand (1) of the distance/travelled (6).

Abstract: A method and strand guide for supporting, guiding and cooling casting strands (1) made of steel, especially preliminary sections (2) for girders, which are cooled by injected water (29) and are drawn, serve to prevent cracks, especially surface cracks, from appearing in the microstructure by adapting the cooling conditions of the surface of the strand in the region of the secondary cooling, and serve to prevent undercooling of the strand shell, wherein in order to avoid an undesirable solidification structure on the upper flange edges or in other cross-sectional areas, the cooling and support of the beam blank format are so adapted to the solidification range that cooling and support are provided exclusively where a crater is formed.

Abstract: The invention relates to a device for the continuous casting of metals, especially steel, by means of a continuous casting mould (1) which is mounted in an oscillating frame (3). Said oscillating frame can be driven so that it oscillates in the direction of casting (2), the course of the oscillation movement and/or the frequency being adjustable. The oscillating frame (3) is mounted with spring assemblies (4a, 4b; 5a, 5b) arranged symmetrically on both sides of the strand, for guiding and weight compensation. The device is used on a continuous casting mould (1) with a shaped casting cross-section (1a), which is mounted in the oscillating frame (3). The leaf-spring-mounted oscillating frame (3) can be operated with the continuous casting mould (1) in a resonance oscillation method in order to give the preliminary section a better surface.

Abstract: A dummy bar for a continuous metal casting plant, particularly for a continuous casting plant for preliminary steel sections, includes a one-piece head piece having dimensions corresponding to the dimensions of the mold cross-section and two rows of segments connected to the head piece. The two rows of segments extend parallel to each other in the longitudinal direction of the dummy bar and are spaced apart from each other by the width of the dummy bar. Flexible steel bands are mounted on each row of segments for connecting the segments.

Abstract: A start-up billet head for a continuous casting machine for metal closes off an outlet of the casting die before start-up of the casting process. The start-up billet head has a coupling part facing an interior of the casting die and forms together with a billet cast in the casting die a positive-locking, hook-shaped connection. The connection can be decoupled after leaving the casting die by performing a tilting movement of the start-up billet head about a joint of the start-up billet. The coupling part has a recess with a first side active in a billet removal direction and a second side facing the first side. The first and second sides have oppositely oriented arc shapes. The coupling part has the shape of a preliminary billet profile with at least one undercut located in the area of at least one flange or angled joint of the preliminary billet profile.
