Process for the controlled pre rolling of thin plates (eslabe) and device appropriate for driving the process, set for the pre - controled rolling of thin plates (eslabe)The combination of a mold for continuous casting

摘要

method of prelaminazione controlled for thin slabs (20) departing from continuous casting in which prelaminazione is performed with a plurality of pairs of rollers (14, 16) arranged in one or more gi broke to prelaminazione (10) being immediately downstream of the rollers at the foot (12) of the mould (11), said pairs of rollers (14, 16) having at least one movable roller (16).these pairs of rolls (14, 16) being associated with means of precision (18) and means (17), a hydraulic capsule being present means of position transducer (24).since these means to transduction of precision (18) and position (24) associated with processing means (21).at least the first of these pairs of rolls (14, 16) working on the slab (20) just out of the lingotteria (11) and a thin pellesolidificata.the group of processing (21) being further associated with both means detecting temperature liquid bath (25a) in a waythat means casting speed detectors (26) and means of temperature detectors (25b) of the slab (20), and the lingotteria outgoing (11) within the group of prelaminazione (10).on the basis of a programme of enslavement and controlby the mutual position of the roller table (16) of at least some of the pairs of rolls (14, 16) to obtain a prelaminazione with reduced thickness of the slab (20) and the last outgoingppia roller of prelaminazione (14 - 16) of at least 10% so as to cancel the heart liquid and lead to biphasic contact areas.is that the solidification structure is refined and the segregation of the central station is minimized.device suitable to carry out the preliminazione controlled thin slabs according to the procedure described above.media temperature detectors with liquid bath (25a) in a means of temperature detectors (25b) slab (20), means (26), readout speed slabmethods detecting presence cone liquid (28).
