Patent

CA 2165083

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.

L'invention concerne un rail de chemin de fer (120) obtenu par laminage d'une billette (102) sensiblement ronde, ainsi qu'un système de fabrication de ce rail. La billette ronde (102) peut être obtenue par des procédés de coulée continue. La billette est d'abord laminée en une forme sensiblement rectangulaire (103) et transformée en rail (120). Le procédé de laminage peut être continu à la chaîne afin de permettre la production de très longs rails sans soudure.
