  • Patent number: 5321966
    Abstract: A method and an arrangement for finish rolling wire and/or round steel on a continuously operating finish rolling block. The finish rolling block includes a plurality of work rolling sets and sizing rolling sets with essentially round sizing rolls, wherein the rolling sets are arranged closely one behind the other and the rolling planes thereof are alternatingly offset relative to each other by 90.degree.. The method includes imparting a twist to the rolled material by asymmetrically spreading the rolled material in the two sets of rolls which precede the last set of rolls, wherein the twist imparted in the two sets of rolls has approximately the same magnitude but is directed in opposite directions, so that the rolled material is stabilized in its position in the last sizing roll pass.

  • Patent number: 5305624
    Abstract: A method and an apparatus for obtaining narrow tolerances of accuracy to pe and size of a rolled product rolled in a wire mill and/or bar mill including at least two sizing stands of high stiffness wherein, with the exception of the last stand, the stands are adjustable under load. The stands cooperate with a device for determining the geometrical data of the rolled product, as well as the relevant rolling operation data. The device is mounted in front of the next-to-last stand for detecting the geometrical data of the rolled product before it enters into the next-to-last stand. The measured values are processed with a sizing model for obtaining a desired exact profile shape in the last roll stand in a computer for forming a signal which is used for adjusting the next-to-last stand.

  • Patent number: 4058154
    Abstract: A roll segment for supporting and guiding continuously cast metal strands fed therethrough, said segment comprising opposing rolls for contacting the opposite sides of a continuously cast metal strand cast through a mold and passed from said mold between said rolls. First support means for supporting the roll in contact with one of said opposite sides of said strand, second support means for supporting the roll in contact with the other of said opposite sides of said strand. Linkage means at the opposite ends of said rolls interconnect said first and second support means and maintain said rolls in substantially parallel alignment at the opposite sides of said strand.
