Abstract:
1. A method of recycling a one-piece rail having a base portion and a head portion spaced from each other along an axis by a substantially flat web portion, said method comprising: heating the material of the rail to a plastic state, feeding the heated rail through a first reduction pass to form a bar having a former head portion, a web portion and a former base portion in which a starting cross section of the rail is reduced in at least one dimension without slitting the rail or the bar, 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 such that the height of the former head portion, the height of the former base portion, and the height of the web portion are substantially equal to each other, slitting the bar along the web portion into two substantially identical pieces, one piece containing the head portion and one piece containing the base portion, as the bar leaves the third reduction pass, rolling the two pieces of the bar through a series of reduction passes to produce a desired final cross section of the bar pieces, whereby both bars are passed through identical shaped rollers to produce substantially identical shaped bar pieces.
