Disclosed is a continuous casting plant comprising at least one robot for carrying out process-controlled or automated interventions on said continuous casting plant and the associated auxiliary devices. In order to ensure optimal use of the robot, - a track (7) is assigned to the continuous casting plant, - a running gear (10) that is movably guided on the track is allocated to the robot, - at least one parked position (P1, P2) and at least two operating positions (E, E1, E2, E3) are defined for the robot on the track while working zones (A1, A2, A3, A4) which can be reached only from one operating position are assigned to each operating position on the continuous casting plant, - the distance between each operating position of the robot and the assigned working zone or supply zone (V1, V2, V3) is defined within the minimum and maximum range of the robot arm (15), and - the robot is equipped with a data transceiver device (20, 21) which is connected in a signaling manner to a central guiding apparatus or a process computer (19) of the continuous casting plant. The invention further relates to a method for operating a continuous casting plant by incorporating at least one robot which can be displaced on a track between a parked position and at least two operating positions.

The invention relates to a method and a device for producing hot-rolled steel strip. To be able to use said device in a combination plant and with a minimum number of rolling passes the method provides for the following combination of steps: continuous casting of steel melt in a cooled, oscillating continuous-casting mould using the free jet casting method, the pouring stream being protected against atmospheric influences; release of an at least partly solidified casting strand with a strand thickness of between 15 and 50 mm from the continuous-casting mould; possible heating of the casting strand to rolling temperature in a heating phase immediately prior to rolling; rolling of the casting strand to a hot-rolled steel strip having a thickness of between 0.6 and 12.0 mm in several rolling passes; and cooling of the steel strip in a cooling line positioned downstream, followed by coiling of the strip in a reeling plant.

The invention relates to a continuous casting mould for the continuous casting of a steel strand, comprising broad side-walls (1, 2) positioned opposite each other as well as narrow side-walls (3, 4) which can be fixed between the broad side-walls, are arranged such that they can be displaced along said broad side-walls perpendicular to the direction of casting (6), are situated opposite each other and in the direction of casting narrow in a wedge-like manner. The broad walls (1, 2) have a funnel-shaped pouring area (20) which extends in the direction of casting (6) until the mould end and the distance between the broad side-walls (1, 2) in the direction of the narrow side-walls (3, 4) and in the direction of casting (6) is reduced continuously at least in partial areas. The broad side-walls (1, 2) are configured such that they converge in the area of displacement of the narrow side-walls (21, 22) in the direction of said narrow side-walls (3, 4). To be able to adjust the dimensions of the mould such that the width of the strand to be cast can be adjusted without effect on strand thickness and the strand thickness of the strand to be cast can be maintained constant across the full strand width the invention provides for the distance between the broad side-walls (1, 2) at the mould end to be constant across the full width of said broad side-walls and for at least one of the broad side-walls (1, 2) to be positioned on a mould carrying structure (11) such that it can be displaced and tilted in relation to the opposite broad side-wall and to be connected to an adjustment device (12, 13).

The invention relates to a device for continuous casting with a mold supporting device (4) and a mold (1) which is mounted in an oscillating manner and located opposite from said supporting device (4). Said mold (1) extends in a crosswise manner (III) over the mold supporting device (4) and supports forces in the elastic area of contained guiding elements (7, 10). The guiding elements (7, 10) are approximately parallel to one another and are arranged in an oscillating direction (III) located above one another at a distance (12). In order to provide high guiding precision during limited space requirements and with only low driving forces for the oscillation drive (14) of the mold (1), a first guiding element (7) extends from the mold supporting device (4) to the mold (1) in a first direction (I) and at least one second guiding element (10) extends from the mold supporting device (4) to the mold (1) in a direction (II) which is opposite the first direction (I).

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.

The invention relates to an internally cooled billet guiding roller, preferably for a continuous casting installation, comprising a central rotary shaft (1) and at least one roller tube (4) which is supported on said shaft in a rotationally fixed manner. The aim of the invention is to ensure that the billet guiding roller is better able to bear mechanical and thermal stresses, is suitable for wide billets, and can be maintained in a cost-efficient manner. To this end, coolant channels (22, 22a, 22b, 22c) pass through the roller tube, said coolant channels being arranged in the roller tube, at a constant distance from the outer surface thereof. Preferably, at least one water diffuser ring (5) is arranged between the roller tube and the central shaft.
