A new hardening technology used in the production of heavy duty rails saves energy and increases productivity. The Siemens’ IdRHa+technology will now be used commercially for the first time in a production line operated by the Chinese steel manufacturer Baotou at its plant in Inner Mongolia. The IdRHa+ (Injector Dual-phase Rail Hardening) system for hardening the rail head makes it possible to produce train rails that can tolerate higher compressive stress and are more fatigue and wear resistant. Siemens developed the technology in cooperation with the Italian Technical CenterCentro Sviluppo Materiali S.p.A. …read more
