  • Patent number: 6626229
    Abstract: A process for producing slabs having a thickness D>100 mm, at casting speeds v<3 m/min, in a continuous casting installation in which melt is supplied to a permanent mold from a storage reservoir via an immersion nozzle and from which, on the aperture side, a strand shell enclosing a liquid crater is withdrawn into a strand guidance frame, in particular a bow-type continuous casting installation. The melt supplied enters the permanent mold at a speed (vK) whose relationship with respect to the strand withdrawal speed (vB) is: vK:vB=6:1 to 60:1, and the flow filaments of the melt supplied are guided in such a way that, with regard to the melt level, they penetrate into the liquid crater over a length L<2 m over a wide front and with a profile which is rectangular in cross section.

  • 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.
