  • Patent number: 7076983
    Abstract: The hot rolling apparatus of the present invention has a mill arranged on the preceding stage, mills of a plurality of stands arranged on the later stage which are different-diameter roll mills including a pair of different-diameter work rolls having an equivalent roll diameter of less than 600 mm or minimum-diameter roll mills including a pair of work rolls having a diameter of less than 600 mm, and a cooling unit for cooling steel to be rolled which is arranged on each exit side of the mills of at least two stands on the later stage. The hot rolling apparatus can smoothly manufacture hot rolled plates of fine-particle steel.

  • Publication number: 20050016242
    Abstract: A continuous hot-rolling mill includes an upper rolling unit including a plurality of rolling stands, and a lower rolling unit including a plurality of rolling stands and disposed downstream with respect to the upper rolling unit in a workpiece passing direction in which a workpiece to be rolled is passed. The two or more rolling stands of the lower rolling unit are differential or very-small-diameter rolling stands. Each of the two or more differential or very-small-diameter rolling stands of the lower rolling unit is provided with a drive motor having a capacity greater than that of any one of drive motors included in the rolling stands disposed upstream the differential or very-small-diameter rolling stands. The continuous hot-rolling mill is suitable for producing hot-rolled, fine-grained steel sheets and is excellent in sheet passing abilities for preventing the steel sheet from meandering and for rolling the steel sheet in a desired shape.

  • Patent number: 6820453
    Abstract: A sheet rolling method uses a rolling mill (10) for rolling a sheet (x). The rolling mill (10) includes upper and lower backup rolls (13, 14), and a pair of work rolls (11, 12) respectively having different diameters and disposed between the upper and the lower backup roll (13, 14). A small-diameter work roll (11) of the pair of work rolls is disposed so that a rotational axis thereof is positioned on a mill center or a downstream side with respect to the mill center in a rolling direction, and the large-diameter work roll (12) is disposed so that a rotational axis thereof is positioned on a downstream side with respect to the rotational axis of the small-diameter work roll (11) in the rolling direction. Thus, mechanical load on the work rolls (11, 12) can be reduced even when a high rolling force is necessary for rolling a wide sheet.
