  • Method of producing shaped rolled sections
    Patent number: 4366693
    Abstract: Proposed herein is a method of producing shaped rolled sections, residing in that the blank is subjected to plastic working by being rolled and cold formed in rolls, with the former put in between the blank and the rolls; the former being made as a rod-like structure arranged lengthwise the axis along which plastic working occurs, whereas the vacant end thereof is brought outside the zone of plastic working.
    Type: Grant

  • Method of making billets
    Patent number: 4288907
    Abstract: A method of making billets, whereby a composite billet is produced by continuous casting or rolling, which billet is star-shaped in cross section and has at least two ray members disposed symmetrically relative to the central longitudinal axis of the composite billet; the base of each star ray member of the composite billet at the place of its juncture with the central portion thereof is selected to be 0.72 to 2.3 of the ray member height, the other base being 0.5 to 1.
    Type: Grant
    Filed: June 28, 1978
    Date of Patent: September 15, 1981
    Inventors: Julian M. Chumanov, Anatoly L. Liberman, Vladimir I. Listopad, Vasily V. Polyakov, Vyacheslav F. Gubaidulin, Grigory M. Shulgin, Dmitry P. Evteev, Sergei P. Efimenko, Veniamin V. Fulmakht, Vladimir P. Slednev, Viktor I. Pogorzhelsky, Valentin B. Shum, Anatoly A. Tolpa
  • Method of rolling section billets
    Patent number: 4204416
    Abstract: The invention relates to a method of rolling section billets in which billets interconnected by bridges are successively formed from a slab in a number of grooves defined by a plurality of transversely juxtaposed passes, with subsequent separation of billets from one another by effecting a relative displacement of adjacent billets by prevailingly acting with a groove on one of the sides of the adjacent billets at an angle other than 90.degree. to the roll axis when the bridge thickness becomes equal to 0.01-0.3 of the groove height.
    Type: Grant
    Filed: December 20, 1977
    Date of Patent: May 27, 1980
    Inventors: Julian M. Chumanov, Vyacheslav F. Gubaidulin, Grigory M. Shulgin, Viktor I. Pogorzhelsky, Vasily P. Morozov, Pavel A. Levichev, Jury P. Lyashenko, Anatoly G. Shalimov, Dmitry P. Evteev, Sergei P. Efimenko, Stanislav N. Ignatiev, Vladimir P. Slednev, Eduard V. Ovsy, Vladimir S. Solod, Valery V. Moiseenkov
  • Method of rolling section billets
    Patent number: 4201075
    Abstract: A method of rolling section billets wherein a plurality of billets transversely interconnected by bridges are successively simultaneously formed from a slab in a number of grooves defined by a plurality of transversely juxtaposed grooves. The forming is effected in two stages by reducing the value of longitudinal tensile stresses in central portions of the billets at one stage by changing the position of zones of prevailing reduction transversely of the billets, with the subsequent separation of billets from one another.
