Abstract: The controlled pre-rolling of a slab, leaving a continuous casting plant is carried out with pairs of pre-rolling elements (14, 114, 16) assembled in at least one pre-rolling assembly (10), the first of these pre-rolling assemblies (10) being positioned immediately downstream of the foot rolls (12) of a crystalliser (11). At least one data processing and controlling unit (21) governs the positioning and the adjustment of the pre-rolling elements (14, 114, 16), the final pre-rolling zone being pre-defined by a specific pair (No.

Abstract: The casting line for slabs comprises at least a mould (11), an assembly of foot rolls (12) located at the outlet of the mould (11), a plurality of containing and guide assemblies (13) associated with the vertical segment of the line, a possible extraction assembly cooperating downstream with the last containing and guide assembly (13) and a drawing assembly (16) associated with the horizontal segment of the line, the containing and guide assemblies (13) covering at least the whole vertical segment of the casting line, at least part of the rolls (14) of the containing and guide assemblies (13) cooperating with an actuator (19) governed by a data processing unit (20) to obtain a controlled soft-reduction pre-rolling at least in the second part of the vertical segment of the casting line.

Abstract: Method for the controlled pre-rolling of thin slabs (20) leaving a continuous casting plant, whereby the pre-rolling is carried out with a plurality of pairs of rolls (14-16), a first pre-rolling assembly (10) being positioned immediately downstream of foot rolls (12) of a mold (11), at least one displaceable roll (16) being included in the pairs of rolls (14-16), the pairs of rolls (14-16) being associated with pressure transducer (18) and hydraulic capsule (17), position transducer (24) being included. The pressure transducer (18) and position transducer (24) can be associated with a data processing unit (21), at least the first of the pairs of rolls (14-16) processing a slab (20) which has just emerged from the mold (11) with a thin solidified skin.

Abstract: Method for the controlled pre-rolling of thin slabs (20) leaving a continuous casting plant, whereby the pre-rolling is carried out with a plurality of pairs of rolls (14-16) grouped together in one or more pre-rolling assemblies (10), the first of the pre-rolling assemblies (10) being positioned immediately downstream of foot rolls (12) of a mold (11), at least one displaceable roll (16) being included in the pairs of rolls (14-16), the pairs of rolls (14-16) being associated with pressure transducer means (18) and hydraulic capsule means (17), position transducer means (24) being included. The pressure transducer means (18) and position transducer means (24) can be associated with a data processing unit (21), at least the first of the pairs of rolls (14-16) processing a slab (20) which has just emerged from the mold (11) with a thin solidified skin.
