STRANGGIESSANLAGE MIT SOFT-REDUCTION-STRECKE

摘要

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.
