  • Patent number: 4802356
    Abstract: A method and apparatus of processing a continuously cast slab to prevent the formation of surface cracks by applying plastic strains to the surface layer of the slab in which a process of solidification is taking place. The method comprises pressing a projection against the slab surface under specified conditions prior to introducing the slab to a leveling stage.
    Type: Grant

  • Patent number: 4619310
    Abstract: A plurality of sets of three rolls are disposed around the periphery of the round continuously drawn from a mold and movable to the direction for or counter to the rounds, the sets being disposed along the drawing direction of the rounds. It is not necessary to replace the apparatus even when the size of the round is changed due to the replacement of molds, as the roll position are adjustable to the rounds.
