New Rail Products at AO EVRAZ ZSMK

Abstract

The production of differentially thermally strengthened general-purpose and special-purpose rails has been introduced at AO EVRAZ ZSMK. This technology is used, for instance, for rails that are reliable at low temperatures, high-speed rails, and rails characterized by increased wear resistance and contact-fatigue life. The plan is to increase the range for rails operating at extremely high speed and especially high stress. With timely maintenance, the properties of the new rails should ensure a life corresponding to a gross load of 2–2.5 billion t.
