  • Patent number: 6598660
    Abstract: A casting mold for continuously casting metal has a pouring area having cooled wide sidewalls and cooled narrow sidewalls. The pouring area tapers in a funnel shape in horizons arranged underneath each other in a casting direction to a format of a strand to be cast, wherein the wide sidewalls are sidewall plates having curved contour areas. At least within one height portion of the casting mold the curved contour areas are asymmetrical relative to a line intercepting center points of the narrow sidewalls.

  • Patent number: 6491088
    Abstract: A disadvantage of continuously casting thin metal strips in a continuous casting plant (1) wherein the casting strand (7) exits the mould (2) in a downward direction and is guided in a vertical strand guide (3) with the help of pairs of driver rolls (4, 5) for supporting and conveying the strand (7), is that the force with which the driver rolls (4, 5) are pressed against the strand (7) results in the unchecked rolling of the strand while it is still soft. The aim of the invention is to solve this problem. To that end, the driver rolls (4, 5) are pressed against the strand (7) with a variable pressure (P1, P2) which is regulated “on-line” in accordance with the thickness (d3, d4) of the strand (7), in such a way as to obtain and maintain a constant strand thickness.

  • Patent number: 6390176
    Abstract: A funnel geometry of a mold for the continuous casting of metal, wherein the mold has a pouring portion with cooled long side walls and short side walls, wherein the pouring portion becomes narrower in the shape of a funnel in the casting direction until it reaches the size of the cast strand. In the funnel portion the inner contour of the long side walls is constructed convexly along a straight line connecting the upper edge of the mold and the outlet of the pouring portion.

  • Patent number: 6363998
    Abstract: A process for producing the oscillation of a continuous casting mold, especially with the use of a hydraulically driven lifting device. So that the heat transfer to the mold and the formation of the casting shell can be effectively controlled, it is proposed that, for any given strand withdrawal rate, the zero line of the mold oscillations relative to the position of the surface of the steel in the mold be moved upward and/or downward during the casting process. As a result of this measure, the quality of the cast product is effectively improved.

  • Patent number: 6186220
    Abstract: A mold for the continuous casting of metal includes a pouring portion with cooled long side walls and short side walls, wherein the pouring portion becomes narrower in the shape of a funnel in the casting direction until it reaches the size of the cast strand. In the funnel portion, the inner contours of the long side walls have in the casting direction from the top toward the bottom at least two points which have the property that they determine a straight line along which the inner contours of the long side walls are formed with at least one concave section and with at least one convex section in any selected sequence.
