发明名称 Railroad rail and method and system of rolling the same by conventional or continuous rolling process
摘要 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.
