Abstract

In several areas of the world, the production of rails is increasing due to the interests generated by the market for high-speed or/and high-load railways. The quality requirements are demanding, and rolling processes and technologies must adapt to the new challenges in order to provide rollers with efficient and profitable plants. Whereas driving factors for rail end-users are “faster, heavier, longer, durable”, the answer from rail producers must be “consistent, reliable, performing, flexible”. This paper presents some of the innovations developed by Siemens in the field of rail production, including EVO rolling stands, idRHa+ head-hardening system and EVO pre-cambering technology.
