Abstract: The invention relates to a method for producing flat and/or elongated products, from for example, thin slabs, thick slabs, billets, blooms, preliminary support sections, or similar, in a production system, by means of a continuous casting installation. Said installation comprises a mould (11), a strand guide (1) with a drawing and straightening machine (2), a cooling section (4) and a separation device (3) for the strand (6), in addition to a compensating furnace or pre-heating furnace (5) that is located downstream. To improve the surface of steel strands, the cooling section (4) is positioned downstream behind the separation device (3), preferably in the immediate vicinity of the compensating furnace or pre-heating furnace (5). The invention also relates to the correspondingly configured production system.

Abstract: A method and strand guide for supporting, guiding and cooling casting strands (1) made of steel, especially preliminary sections (2) for girders, which are cooled by injected water (29) and are drawn. The inventive method prevents cracks, especially surface cracks, from appearing in the microstructure by adapting the cooling conditions of the surface of the strand during secondary cooling. Undercooling of the chill of the strand is prevented by adapting the cooling and support of the beam blank format to the solidification range in order to avoid an undesirable solidification structure on the upper flange edges or in other cross-sectional areas so that cooling and support are provided exclusively where a crater is formed. The casting strand (1) is cooled by guiding the temperature in a specific manner in upper supporting segments (5, 6, 7) by means of injected water jets whose width at least matches the length of the supporting rollers on longitudinal and transversal sides (13, 14) of the cross section (1a) of the casting strand, and is decreasingly supported in an analogous manner with respect to the length of the casting path and the cooling state in core areas (15) of the cross section (1a) of the casting strand on the transversal sides (14) of said casting strand cross section (1a) and cooling occurs exclusively by means of water jets (8) which are oriented towards said core areas (15).

Abstract: The invention relates to a method for collecting and evacuating run-off water from the inner arc of the strand guide (8) of a beam blank casting machine, according to which the cast strand (2) is solidified and the required dissipation of heat is achieved, among other things, by sprayed water, whereby run-off water can also collect on the inner arc of the strand (2). The run-off water is collected using a suction head (1). The run-off water that is collected in the suction head is fluidised using fluidisers or momentum inhibitors. The fluidised water is sucked off and the water-air mixture is split into water and air in a separation device. The invention also relates to a device for carrying out said method, comprising at least one suction device that is arranged or can be driven along the strand guide (8), said suction device having an attachable suction head (1) and being equipped with fluidisers. The suction device (4) is driven along the beam blank preliminary section (9) by means of manipulators (7).

Abstract: The invention relates to a continuous casting mould (1) for liquid metal (2), especially for liquid steel (2a), comprising an upper flange (3) arranged on the entrance region of the mould (1a) and a lower flange (4) situated beneath. The upper flange (3) and the lower flange (4) form a lubricating gap (5) and an outlet slit (8) surrounding the hot sides (6) of the inner chamber of the mould (1b), for a lubricant (7). The lubricant is thus reliably guided and supplied in order to maintain a required regular, uninterrupted lubricant flow, due to the fact that the upper flange (3) and the lower flange (4) form a lubricating gap (5) for the liquid lubricant (7), said gap being evenly defined on both sides, and that the lubricating gap (5) comprises a labyrinth-type course (11) in the flow direction (9) before the lubricant outlet (10).

Abstract: The invention relates to a method and a device for draining waste water (7) from the inner bend of the strand guide (3) of a beam blank casting machine. In order to drain said waste water from the beam blank in a targeted and controlled manner, a draining device (6) is arranged in the area of the strand guide (4) for the beam blank, said device being provided with jet nozzles (8). Under the effect of jets (13, 14) directed with high energy against the water flow direction, the waste water is lifted on the formation of a banking-up pressure by means of said draining device (6), directed at the lateral edges (11) of the inner bend (4) of the beam blank (10) and collected in a sintered groove (9), arranged thereunder.

Abstract: The invention relates to a method and a continuous casting device for the direct shaping of a metal strand, in particular a steel cast strand (1) of any format (1d). According to said method, the cast strand (1) is only cooled by a liquid coolant (4) in longitudinal sections (6), where the interior of the cast strand (1) remains liquefied and the temperature of the cast strand (1) in a transition zone (7) upstream of, in and/or downstream of a bending and straightening unit (8) is evened out by an insulation of the exterior surface (1 b), essentially without the use of a liquid coolant (4), and by progressive thermal radiation. The cast strand (1) is shaped in a dynamically variable reduction section (9) as a result of the compressive strength that is measured on individual shaping rolls (10) or roll segments (11), depending on the compressive force that can be locally applied.
