  • Publication number: 20100084108
    Abstract: A continuous casting mold with two narrow mold sides opposite one another and two longitudinal mold sides opposite one another. At least one of the narrow mold sides is movable toward and away from the other by means of hydraulic cylinders on the opposite narrow mold side. The hydraulic cylinders can be actuated independently from one another and have, in each instance, a cylinder and a piston guided therein. The piston rod of the piston is connected to the narrow mold side that is to be displaced, and a device for acquiring the position of the piston and, therefore, the displacement of the narrow mold side, is associated with at least one of the hydraulic cylinders. To improve the determination of the position of the narrow mold side, a displacement measuring system is arranged parallel to the hydraulic cylinder and constructed such that its measurement path directly corresponds to the displacement of the piston of the hydraulic cylinder.

  • Patent number: 7500510
    Abstract: An oscillating device for continuous casting molds (1) for casting molten metal particularly, molten steel material includes a plurality of springs (5) or spring assemblies (5a) extending between a stationary mold frame (2) and connection or fixing points (4) for supporting a continuous casting mold (1) and are set in control oscillations such as, e.g., resonance oscillations by drive pairs, wherein by using of springs (5), spring assemblies (5a) or spring bundles (5b) formed of fiber composites (6), damaging corrosion by chemicals during continuous casting is prevented.

  • Patent number: 6942011
    Abstract: The invention relates to a mold divider for fitting in a conventional slab mold (1) having laterally adjustable narrow-side parts for selective casting of several strands with changeable strand widths. The mold divider consists of a housing (3) fixedly securable relative to the mold (1), between the broad-side plates (2) and having bilaterally adjustable, in a broad-side direction of the mold (1), adjusting organs (4), with supporting plates (5) provided at their ends and with the narrow-side heat-exchanger plates (6) arranged thereon.

  • Patent number: 5727615
    Abstract: A mold arrangement for the production of endless castings of metal, particularly slabs of steel, having copper plates for the wide sides of the mold which rest on coolable support plates, and narrow sides which can be clamped between the wide sides. Additionally, an oscillating device is connected with the support plates. The support plates are trough-shaped in the region of the mold wide sides. Channels are provided in the wall of the support plates for the passage of a cooling fluid. Electromagnetic structural parts arranged on mounting frames can be freely introduced into the trough free space which faces away from the wide sides.
