Abstract: The invention relates to a method and a device for the continuous casting of slabs or ingots, in particular of thin slabs in a continuous casting installation. Said installation comprises a soft reduction section in a continuous casting guide under the mould. The soft reduction section contains pressure rollers and support roller (3, 4), which are continuously restrained in relation to one another, either individually or as a segment (1), by means of hydraulic cylinders (7, 7') and are restrained in a limiting manner by stops (30). The installation uses a hard-pressure restraining force in an area of the soft reduction section that has not yet completely solidified and a soft-pressure restraining force in an area of the soft reduction section that has completely solidified. Threshold and changeover values for the hard and soft-pressure are defined in the segment is restrained using hard-pressure, such a way that if the restraining force lies below the threshold or changeover value, and if the restraining force lies above the threshold or changeover value the segment is restrained using soft-pressure.

Abstract: Procedimiento para la colada continua de desbastes planos o bloques, especialmente de desbastes lisos en una instalación de colada continua, que comprende en una conducción de la colada debajo de la coquilla una sección de reducción blanda con rodillos de presión o bien rodillos de apoyo (3, 4), que están impulsados de forma individual o como segmento (1) por medio de cilindros hidráulicos (7, 7¿) sin escalonamiento unos hacia los otros así como por medio de topes (30) en una medida limitada con una fuerza de sujeción variable, caracterizado porque dentro de una zona de la sección de reducción blanda, en la que la colada no está todavía solidificada, se trabaja con una fuerza de sujeción con presión dura, y dentro de la zona de la sección de reducción blanda, en la que la colada está endurecida, se trabaja con una fuerza de sujeción con presión blanda, porque se definen valores límite o bien valores de conmutación para la presión dura y la presión blanda y porque en el caso de una fuerza desujeción por debajo del valor límite o valor de conmutación se lleva a cabo la sujeción del segmento con presión dura y en el caso de una fuerza de sujeción por encima del valor límite o valor de conmutación se realiza la sujeción del segmento con presión blanda.

Abstract: The invention relates to a method and a device for the continuous casting of slabs or ingots, in particular of thin slabs in a continuous casting installation. Said installation comprises a soft reduction section in a continuous casting guide under the mould. The soft reduction section contain s pressure rollers and support rollers (3, 4), which are continuously restrain ed in relation to one another, either individually or as a segment (1), by mean s of hydraulic cylinders (7, 7') and are restrained in a limiting manner by stops (30). The installation uses a hard-pressure restraining force in an ar ea of the soft reduction section that has not yet completely solidified and a soft-pressure restraining force in an area of the soft reduction section tha t has completely solidified. Threshold and changeover values for the hard and soft pressure are defined in such a way that if the restraining force lies below the threshold or changeover value, the segment is restrained using har d pressure and if said restraining force lies above the threshold or changeove r value, the segment is restrained using soft pressure.
