  • Patent number: 5467809
    Abstract: A liquid-cooled plate mold with adjustable width for the continuous casting of billets from steel in the form of slabs, particularly for a slab thickness of less than 100 mm. The shape-imparting broad side plates (1) and narrow side plates (2) of the ingot mold are constructed in the direction of their transverse extension so as to increase in cross section for the billet, while the narrow side plates (2) extend substantially parallel to one another along the height of the ingot mold. Further, the broad side plates (1) are constructed so as to be concave at least in a region (3) of smallest slab width in such a way that, in cross section, the apex height (13) of the ingot mold wall forming a curve has a determined height relative to a rectangle inserted in the drawing. The shape of the billet side plates at the billet outlet end (5) corresponds to the billet format to be produced.

  • Patent number: 5335714
    Abstract: The invention relates to a dummy bar for continuous casting installations with a curved bar guide arranged downstream of a mold. The invention provides a dummy bar which is characterized by a flexible metallic strip (1) and components (3) which are fastened to a surface of the strip (1) for detachably connecting with spacers (2) extending in the shape of strips along the width of the strip (1) on the same surface transversely to the longitudinal direction of the strip, which spacers (2) have mutually adjacent contact areas (6) at least in the region of the components (3). The free surface of the spacers (2) is covered with congruent rubber-like plates (5) and the free surface of the strip (1) is provided with a rubber-like coating (4).
