Abstract: A method and a device for producing steel strips by belt casting, wherein a molten metal is output from a feed vessel onto a circulating casting belt of a horizontal belt casting system under protective gas by a gutter and a siphon-like outlet area designed as a casting nozzle. At least one plasma jet, which renders the area of action inert and heats the area of action, influences the outlet-side area of the casting nozzle and the molten metal exiting therefrom at least during the casting process. For this purpose, at least one plasma torch, which produces a plasma jet and is directed at the outlet area of the casting nozzle in a direction opposite the casting direction, is provided.

Abstract: The invention relates to a casting nozzle for a horizontal strip casting system, especially for casting steel strip. The casting nozzle is connected to a feed channel and is designed as a rectangular refractory hollow block, the outlet region of which being only slightly above the cooled continuous belt which accommodates the outflowing melt. The hollow block is subdivided at least once in the direction of casting and a narrow sealing element is arranged on the partition side of the segments, the width of the remaining gaps in the partition area being selected as to close when the casting nozzle is operated.

Abstract: An apparatus for casting near-net-shape, rectangular metal strands includes a horizontally circulating metal conveyor belt (7) with a cooled bottom a melt feeder (3?) for casting the metal onto the conveyor belt(7), and an arrangement for feeding the solidified pre-strip under mechanical tension to a driver (16). A cooled pressure device (11, 12, 13) is arranged above the cast product (4) in a region of the deflection roller (8) of the metal conveyor belt (7) which is located downstream in a casting direction, for applying an adjustable pressure from above to the cast product (4) solidifying into the pre-strip (5); and immediately behind the metal conveyor belt (7) a cooling device (17, 19, 19?)for cooling the bottom of the pre-strip (5) over its entire width.

Abstract: A method of casting near-net-shape, rectangular metal strands includes providing a horizontally circulating metal conveyor belt (7) with a cooled bottom and a melt feeder (3?) for casting the metal melt onto the conveyor belt (7), smooth/pinch rollers (14) for feeding the solidified pre-strip under mechanical tension to a driver (16), a pressure device (11, 12, 13) arranged above the cast product (4) in a region of the deflection roller (8) of the metal conveyor belt (7) which is located downstream in a casting direction, for applying an adjustable pressure from above to the cast product (4) solidifying into the pre-strip (5). Immediately behind the metal conveyor belt (7) and upstream of the pinch rollers, a cooling device (17, 19, 19?) is provided for cooling the bottom of the pre-strip (5) after the pre-strip leaves the conveyor belt.

Abstract: The invention relates to a method and a device for producing steel strips by means of belt casting, wherein a molten metal is output from a feed vessel onto a circulating casting belt of a horizontal belt casting system under protective gas by means of a gutter and a siphon-like outlet area designed as a casting nozzle. According to the method, at least one plasma jet, which renders the area of action inert and heats the area of action, influences the outlet-side area of the casting nozzle and the molten metal exiting therefrom at least during the casting process. For this purpose, at least one plasma torch, which produces a plasma jet and is directed at the outlet area of the casting nozzle in a direction opposite the casting direction, is provided according to the device.

Abstract: The method of casting near net-shape rectangular strands made of metal and the subsequent further processing the strands into metal strips includes applying pressure from above to the cast product (4) solidifying into the preliminary strip (5), preferably to its strip edges (6) by means of a pressure device (11) disposed at the end of the metal conveyor belt (7) and, additionally cooling of the bottom of the preliminary strip in a predetermined area directly behind the metal conveyor belt (7).

Abstract: The invention relates to a burner arrangement (1) in particular for heating, drying or keeping warm, in particular a distributor (5) of a continuous casting unit and consisting of a flat arrangement of at least one burner (2). The burner(s) (2) is/are embodied as a porous burner (10).

Abstract: The invention relates to a burner arrangement (1) in particular for heating or keeping warm, in particular casting stream protection devices and/or immersion casting devices of a continuous casting plant, comprising a reservoir (5) that can receive, in particular a shroud tube or an immersion tube, said reservoir comprising a base (6) and a cover (7). The wall (8) of the reservoir (5) is formed by at least one porous burner.

Abstract: A method and a device for weighing the contents of a metallurgical vessel (2), especially the contents of a tundish (3) in a steel continuous casting plant, whereby the vessel is supported on hydraulically actuatable weighing elements serving to increase the measurement precision before and during the metallurgical process and resides in that the filling weight is calculated by computer from hydraulic pressures in cylinder chamber (8a; 9a; 10a; 11a) which are measured deducting the empty weight of the vessel (2) and the friction forces in the cylinder chambers (8a; 9a; 10a; 11a).
