  • Patent number: 5601138
    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.

  • Patent number: 5488987
    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.

  • Patent number: 5343931
    Abstract: Crystallizer, or inner portion, of a mold for the continuous curved casting of thin slabs, which has at least its outer curved extrados plate (10) containing a substantially central enlargement hollow (11) starting from the upper surface (13) of the outer plate (10) and being reduced progressively, to zero in the curved inner surface (12) of the plate (10) for sliding of the molten metal, the enlargement hollow (11) being defined by a determined profile, the profile being determined lengthwise by an angle ".alpha." and crosswise by an angle ".beta.", wherein the angle ".alpha." should not exceed a maximum value of 5.degree. and may vary, from the center line to the sides of the hollow (11), according to a linear development contained within a field limited at its upper end by that maximum value and at its lower end by zero.

  • Patent number: 5339877
    Abstract: Crystallizer, or inner portion, of a mould having a lengthwise curvature for continuous curved casting of thin slabs (20), the crystallizer comprising an outer, or extrados, plate (12), an inner, or intrados, plate (11) and lateral narrow plates (13s-13d) having inner faces (16) defining a casting section (14), the lateral narrow plates (13s-13d) having their inner faces (16) inclined in such a way as to impart to the downflow channel a tapered conformation which reduces the width of the casting section (14) in the direction of feed of the thin slabs (20), both the extrados (12) and intrados (11) plates being curved lengthwise and containing in their inner upper central portion respective frontal extrados (15) and intrados (115) hollows, the upper part of the inner face (16) of the lateral narrow plates (13s-13d) comprising a bevel (17) which faces towards the intrados plate (11) and is progressively reduced to zero in the vicinity of the level of the lower end of the extrados (15) and intrados (115) hollows.
