  • Patent number: 8579012
    Abstract: Exemplary embodiments of the invention provide a casting apparatus for continuously casting a metal strip article (e.g. a twin-belt metal caster or a twin-block metal caster). The apparatus has a casting cavity defined between a pair of moving elongated opposed casting surfaces, and the casting cavity has an entrance and an exit aligned in a direction of casting. The casting cavity is also provided with a molten metal injector at its entrance, the injector having an internal metal channel including a downstream opening for introducing molten metal into the casting cavity, and a pair of side dams at each lateral side of the casting cavity for confining molten metal from the injector within the cavity. At least one of the side dams comprises an elongated element that is movable laterally relative to the direction of casting during a casting operation.

  • Patent number: 8509942
    Abstract: Surface 27 of molten metal within a mold is constantly monitored by camera 25. Camera 25 records the surface from an obliquely upward position of the mold in an area that does not affect the casting process. Various analyzing frames such as analysis band 35, molten metal pattern 37, and injection monitoring part 43, are set with respect to the information recorded by the camera 25. The analysis band 35 includes the surface (molten metal part 31c), and is set to a predetermined width so that the direction of surface change is in the longitudinal direction. The width of the analysis band 35 is set as wide as possible in a range that does not block the discharge part (molten metal part 31a). Inside the analysis band 35, the rate of change of the binary data is calculated by the analyzing part.

  • Publication number: 20130199677
    Abstract: An improved magnesium-based alloy for wrought applications is disclosed, including a method of fabricating alloy sheet from said alloy. The improved magnesium-based alloy consists of: 0.5 to 4.0% by weight zinc; 0.02 to 0.70% by weight a rare earth element, or mixture of the same including gadolinium; and incidental impurities. The rare earth clement in some embodiments may be yttrium and/or gadolinium. In some embodiments the magnesium-based alloy may also consist of a grain refiner and in some embodiments the grain refiner may be zirconium. In combination, the inclusion of zinc and a rare earth element, into the magnesium alloy may have enhanced capacity for rolling workability, deep drawing at low temperatures and stretch formability at room temperature. The improved alloy may also exhibit increased tensile strength and formability while evincing a reduced tendency for tearing during preparation.

  • Publication number: 20130192790
    Abstract: A method is disclosed for continuously or semi-continuously producing hot steel strip which, starting from a slab guided through a slab-guiding device, is rolled in a roughing train having at least four-stands, the method comprising: casting a slab in a die, the slab being reduced to a thickness of between 60 and 95 mm in a liquid core reduction process by the adjoining slab-guiding device, a slab support length measured between the meniscus, i.e., the bath level, of the die and an end of the slab-guiding device facing the roughing train being between 12 m and 15.5 m, and a casting speed ranging from 3.8 to 7 m/min. The disclosed combination of casting parameters may ensure that the crater tip of the slab extends to the vicinity of the end of the slab-guiding device independently of the respective maximum casting speeds which are dependent on the particular grade of material.

  • Publication number: 20130186588
    Abstract: A method is disclosed for continuously or semi-continuously producing hot steel strip which, starting from a slab guided through a slab-guiding device, is rolled in, for example, an at least four-stand roughing train to form an intermediate strip and, in a further sequence in a finish rolling train, into a final strip. The thickness of a slab cast in a die is reduced in the liquid core reduction process by means of the adjoining slab-guiding device to between 85 and 120 mm, a slab support length measured between the meniscus, i.e., the bath level, of the die and an end of the slab-guiding device facing the roughing train being at least 18.5 m, a casting speed ranging from 3.8 to 7 m/min, and slabs of different thicknesses being cast as a function of given casting speeds. Using the disclosed casting parameters, high-quality finishing may be provided with high production capacities.
