By Means (other Than A Tool) Modifying Temperature Of Work Patents (Class 72/202)
  • Patent number: 4263798
    Abstract: A hot rolling mill and a method of operation to reduce scrap upon failure of a portion of the mill in which a first furnace device is provided adapted to receive and reel up a strip which is ready to go to the finishing section of the mill and a second furnace device is provided to receive a strip of material being rolled in the roughing section of the mill without reeling up, while both furnace devices maintain the material therein at working temperature and in continuous motion.
    Type: Grant

  • Patent number: 4150279
    Abstract: Methods of forming metallic workpieces into ring-shaped components of selected cross-sectional configuration in which roll electrodes both heat the workpiece by electrical resistance and provide the pressure so that the workpiece becomes plastic and flows into the wanted configuration. Apparatus in which the method can be carried out, and tooling for controlling the configuration into which the workpiece is formed.

  • Patent number: 4067220
    Abstract: A method for rolling out a slab, preferably a slab produced by continuous casting, to form a billet having a square cross section, in which the width of the slab is reduced by repeated powerful edging passes, a temperature drop starting from the central region of the slab being provided during rolling, for example by spraying the edge regions of the slab with coolant, in order to give the edge regions greater deformation resistance and thus to prevent bulges at the edge regions. The bulge occurring in the central region of the slab is rolled away by guide rollers located at right-angles to the edging rolls. A rolling mill with suitable heating means is also provided.

  • Patent number: 3964938
    Abstract: The specification discloses a completely automated method and apparatus for producing high tensile steel, of a controlled, predetermined U.T.S. and cross sectional area, from low and medium carbon steel by subjecting the steel to substantial elongation while simultaneously substantially heating and immediately thereafter rapidly quenching the steel, and while continually moving the steel relative to the heating and quenching means employed. The steel is heated to a temperature above its austenite conversion temperature. Greater elongation produces greater ultimate tensile strength, as much as more than twice as great as the starting ultimate tensile strength, and elongations approaching 200 percent have been effected.
