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 seconda ry cooling, and serve to prevent undercooling of the strand shell, wherein in order to avoid an undesirable solidification structure on the upper flange edges o r in other cross-sectional areas, the cooling and support of the beam blank forma t are so adapted to the solidification range that cooling and support are provided exclusively where a crater is formed. To this end, the casting strand (1) is cooled, by guiding the temperature in a specific manner in upper supporting segments (5, 6, 7), by means of spray-water jets the width of which at least matches the length of the supporting rollers on longitudinal and transversal sides (13, 14) of the cross section (la) of the casting strand, and is decreasingly supported in an analogous manner with respect to the length of the casting path and the cooling state in core areas (15) of the cross section (la) of the casting strand on the transversal sides (14) of said casting strand cross-section (1 a) so that cooling occurs exclusively by means of water jets (8) which are oriente d towards said core areas (15).

Abstract: Procedimiento para soportar, guiar y enfriar barras de acero fundidas, especialmente de perfiles previos para vigas, en el que la barra fundida, después de salir de la coquilla de fundición continua, se enfría y se expulsa fuera a un segmento cero en un enfriamiento secundario y, adicionalmente, en segmentos de soporte subsiguientes, mediante agua de inyección, caracterizado porque, para evitar una estructura de solidificación no deseada en los bordes superiores de las aletas o en otras zonas de la sección transversal, el enfriamiento y soporte del formato `beam blank¿ está adaptado a la zonas de solidificación de tal manera que sólo se produce el enfriamiento y soporte en la zonas en que haya formación de fase líquida.

Abstract: A method and strand guide for supporting, guiding and cooling casting strand s (1) made of steel, especially preliminary sections (2) for girders, which ar e cooled by injected water (29) and are drawn. The inventive method prevents cracks, especially surface cracks, from appearing in the microstructure by adapting the cooling conditions of the surface of the strand during secondar y cooling. Undercooling of the chill of the strand is prevented by adapting th e cooling and support of the beam blank format to the solidification range in order to avoid an undesirable solidification structure on the upper flange edges or in other cross-sectional areas so that cooling and support are provided exclusively where a crater is formed. The casting strand (1) is cooled by guiding the temperature in a specific manner in upper supporting segments (5, 6, 7) by means of injected water jets whose width at least matches the length of the supporting rollers on longitudinal and transversal sides (13, 14) of the cross section (1a) of the casting strand, and is decreasingly supported in an analogous manner with respect to the length of the casting path and the cooling state in core areas (15) of the cross secti on (1a) of the casting strand on the transversal sides (14) of said casting strand cross section (1a) andcooling occurs exclusively by means of water jets (8) which are oriented towards said core areas (15).

Abstract: Continuous metal casting assembly has a continuous casting mold (1) with a profiled casting cross section (1a), mounted in a swing frame (3). The swing frame, in a leaf spring mounting, is operated with a resonance oscillation. The casting cross section has a dog-bone shape. The oscillating drive (6) has an adjustable oscillating stroke and/or frequency and/or curve.

Abstract: The invention relates to a device for the continuous casting of metals, especially steel, by means of a continuous casting mold ( 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 ( 4 a , 4 b ; 5 a , 5 b) arranged symmetrically on both sides of the strand, for guiding and weight compensation. The device is used on a continuous casting mold ( 1 ) with a shaped casting cross-section ( 1 a), which is mounted in the oscillating frame ( 3 ). The leaf-spring-mounted oscillating frame ( 3 ) can be operated with the continuous casting mold ( 1 ) in a resonance oscillation method in order to give the preliminary section a better surface.
