  • Patent number: 6021842
    Abstract: A stationary continuous casting mold, especially for casting steel, with an electromagnetic device having a plurality of stirrer elements which are arranged in pairs on the outer wall of the continuous casting mold at a distance from one another and are connected to an electric a.c. voltage. The stirrer elements include at least two pairs and the stirrer elements of each pair are arranged opposite one another and so as to be rotated at an angle relative to one another in an X-shaped configuration in a plane parallel to the casting direction. All pairs are arranged at substantially the same height.

  • Patent number: 5771957
    Abstract: A device for the continuous casting of steel, consisting of a continuous casting mold which oscillates in the casting direction, is mounted on springs clamped at both ends which extend transverse to the direction of casting, and is connected with a hydraulic oscillation drive. The the hydraulic oscillation drives are servo-hydraulic cylinders, arranged in a longitudinal sectional plane placed through the continuous casting mold laterally alongside the continuous casting mold, the servo-hydraulic cylinders are firmly connected, free of play, to a support frame and with the continuous casting mold.

  • 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.
