摘要： The invention relates to a continuous casting plant for optionally casting a large metal billet or a maximum of two narrower metal billets. Said continuous casting plant comprises at least one distribution vessel, a permanent mold that is supported on an oscillating mechanism, and a billet guide which is mounted downstream thereof. In order to be able to individually cast both a large billet and two metal billets that are narrower than said large one, the continuous casting plant encompasses a chamber (25) for optionally accommodating one (5) or two permanent molds (5a, 5b) while two oscillating mechanisms (7a, 7b) and two billet guides (8a, 8b) with associated drive units (41) for separately and synchronously operating the oscillating mechanism and the billet guide are provided.

摘要： The invention relates to a method for continuously casting a metal strand, especially a steel strand (1). According to the method, a strand (1) is drawn out of a cooled open-ended mold (3), is supported in a strand supporting device (7, 11) located downstream from the open-ended mold (3), is cooled by a coolant, and optionally undergoes a thickness reduction. The aim of the invention is to stipulate the formation of a desired structure of the metal. To this end, the continuous casting is carried out with online calculation while using, as a basis, an arithmetic model which describes the formation of the defined structure of the metal, whereby the variables of the continuous casting method which influence the structuring, e.g. the specific amount of coolant provided for cooling the strand, are set in an online dynamic manner, i.e. during continuous casting.

摘要： The invention relates to an open-ended mould for casting metal strands having a thin slab cross-section, in which the wide lateral walls (1, 2) form a central enlarging region (11) extending from the mould inlet edge (5) to the mould outlet edge (6), and opening up in a rectangular outlet cross-section (22). The aim of the invention is to prevent, to a large extent, strands from detaching themselves from the wide lateral walls. To this end, the contour of the mould cavity (7) in the enlarging area (11) is formed, in cutting planes which are perpendicular to a longitudinal axis (23) of the mould, by curves (15) which form, at least in partial regions, clothoid curves (18, 19, 20, 21) or clothoid-type curves, in which the curvature variations ( DELTA k) are minimised or reduced to zero.
