Definitions

  • the bridle roll 16 B is the downstream one of the bridle rolls 16 A, 16 B disposed at the outlet portion 4 of the furnace 3 .
  • FIGS. 6 and 7 are graphs showing an example of a relationship between the apparent diameter D 2 of the correction roll 18 and the warpage amount w of the metal strip 2 at the exit side of the sink roll 20 of the warpage correction apparatus 1 according to Example and Comparative Example, respectively.
  • FIG. 6 is a graph when the diameter D 1 of the bridle roll 16 B (fixed roll) is 800 mm, the diameter D 3 of the sink roll 20 is 2000 mm, D 3 /D 1 is 2.5 in the warpage correction apparatus 1 described above.
  • FIG. 7 is a graph when D 1 is 800 mm, D 3 is 900 mm, D 3 /D 1 is 1.1 in the warpage correction apparatus 1 described above.
  • “t” represents the thickness of the metal strip 2 .
  • the warpage correction apparatus 1 may further include a controller (not shown) configured to adjust the pressing amount d 2 of the correction roll 18 toward the metal strip 2 based on a measurement result of the warpage amount by the warpage measuring device 12 .
  • the metal strip may warp in the strip width direction (hereinafter, referred to as “C-warp” or simply “warpage”) at the exit side of each roll.
  • C-warp the strip width direction
  • the ratio D 3 /D 1 of the diameter D 3 of the sink roll to the diameter D 1 of the fixed roll increases, it is possible to expand the adjustable range of warpage amount in the strip width direction at the exit side of the sink roll by adjusting the apparent diameter D 2 of the correction roll, and it is possible to bring the warpage amount of a thicker metal strip close to zero.
  • the bridle roll is generally disposed at the outlet portion of the furnace and thus tends to be a primary cause of warpage in the strip width direction at the entry side of the correction roll.
  • an expression of relative or absolute arrangement such as “in a direction”, “along a direction”, “parallel”, “orthogonal”, “centered”, “concentric” and “coaxial” shall not be construed as indicating only the arrangement in a strict literal sense, but also includes a state where the arrangement is relatively displaced by a tolerance, or by an angle or a distance whereby it is possible to achieve the same function.
