| 摘要 |
The invention concerns a rail, preferably a flanged rail comprising, cast integral by reduction rolling of a semi-finished product coated on its face designed to form the flange (8) with a coat of material for reinforcement against wear, a coating made of said material continuously covering at least the active surface (7) of the railhead (3) rolling surface (6) and rail shoulder (13), and preferably also the fillet (16) connecting the outer flank (10) of the flange (8) with the edge strip (11). Such a rail is preferably used for constructing railway lines for urban transport vehicles such as tramways or light rail rapid transit, for reducing wear and noise pollution. |
