RAILROAD RAIL AND METHOD AND SYSTEM OF ROLLING THE SAME BY CONVENTIONAL OR CONTINUOUS ROLLING PROCESS |
| 摘要 |
A railroad rail (120) produced by rolling a substantially round bloom (102), together with a system for manufacturing the same. The round bloom (102) may be produced by continuous casting methods. The bloom is initially rolled into a substantially rectangular shape (103) and then into a rail (120). The rolling process may be continuous and in-line to allow for the production of very long seamless rails. |
