  • Device and method for manufacturing hot-rolled sheet steel and device and method for sheet thickness pressing used for the device and method
    Patent number: 6722174
    Abstract: According to an apparatus and a method for manufacturing a hot-rolled steel plate, a roughing process for reducing a thickness of a continuously cast slab is performed to obtain a sheet bar, and a finishing rolling process for rolling the sheet bar is effected to produce a hot-rolled steel plate having a predetermined plate thickness. After cooling down, the hot-rolled steel plate is then wound. A pair of dies 6 each of which has a tapered portion 6b on an input side and a parallel portion 6b on an output side are used in at least part of the roughing process. Further, before performing plate thickness pressing to a material in a plate thickness direction by using the dies 6, at least one of a front end and a rear end of the material is pressed in a widthwise direction to be pre-formed.

  • Rolling mill with laterally different velocities
    Patent number: 6065319
    Abstract: Each of a pair of rolls has a barrel with different diameters axially of the barrel such that sum of the diameters of the barrels is substantially constant and that each of the rolls is bilaterally symmetrical. The rolls themselves have an ability to control workpiece profile and have at least one substantially parallel center portion.
