  • No-slit hot rolling of railroad rails
    Patent number: 9168575
    Abstract: A method of recycling a one-piece rail having a base portion and a head portion spaced from each other by a substantially flat web portion. The steps include: heating the rail to a plastic state; feeding the heated rail through a first reduction pass to reduce a cross section of the rail without slitting the rail; feeding the bar through a second reduction pass in which the cross section of the bar is further modified; feeding the bar through a third reduction pass in which the cross section of the bar is further modified and then slitting the bar along the web portion into two bar pieces, one containing the former head portion and one containing the former base portion, as the bar leaves the third reduction pass; and rolling the two bar pieces through a series of reduction passes to produce a desired final cross section of the pieces.

  • No-slit hot rolling of railroad rails
    Patent number: 9067248
    Abstract: A method of recycling a one-piece rail having a base portion and a head portion spaced from each other by a substantially flat web portion. The steps include: heating the rail to a plastic state; feeding the heated rail through a first reduction pass to reduce a cross section of the rail without slitting the rail, thereby forming a bar; feeding the bar through a second reduction pass in which the cross section of the bar is further modified and then slitting the bar along the web portion into two bar pieces, one containing the former head portion and one containing the former base portion, as the bar leaves the second reduction pass; and rolling the two bar pieces, in a single pass line, through a series of reduction passes to produce a desired final cross section of the pieces.

    Publication number: 20130074566
    Abstract: A method of recycling a one-piece rail having a base portion and a head portion spaced from each other by a substantially flat web portion. The steps include: heating the rail to a plastic state; feeding the heated rail through a first reduction pass to reduce a cross section of the rail without slitting the rail; feeding the rod through a second reduction pass in which the cross section of the rod is further modified and then slitting the rod along the web portion into two rod pieces, one containing the former head portion and one containing the former base portion, as the rod leaves the second reduction pass; and rolling the two rod pieces, in a single pass line, through a series of reduction passes to produce a desired final cross section of the pieces.
