  • Conventional or continuous rolling process
    Patent number: 5666707
    Abstract: A railroad rail produced by rolling a substantially round bloom, together with a process and system for manufacturing the same. The round bloom may be produced by continuous casting methods. The bloom is initially rolled into a substantially rectangular shape and then into a rail. The rolling process may be continuous and in-line to allow for the production of very long seamless rails.
    Type: Grant
    Filed: June 30, 1995
    Date of Patent: September 16, 1997
    Assignee: CF&I Steel, L.P.
    Inventors: Robert L. Cryderman, John C. Winkley

  • Continuous rail production
    Patent number: 5419387
    Abstract: A superior unitary one quarter mile long railroad rail and system and method for manufacturing the same. The method of manufacture is characterized by the use of a continuous rolling process and the in-line controlled cooling of the rail. The system produces very long rails without any weld seams.
