Abstract
The article presents the research results obtained during working out and industrial development of technology of the differentiated thermal treatment by air of railway rails with the use of heat of rolling heating. The work was performed in the conditions of JSC «EVRAZ ZSMK» during reconstruction of the rail manufacture. In the paper the authors describe the results of investigation of the influence of a chemical compound, modes of plastic deformation and thermal processing on the position of polymorphic transformation points, as well as the construction of thermokinetic diagrams of steels of a skilled chemical compound. Cooling rate on the section of a rail head depending on heat treatment parameters was investigated. The rational chemical compound and modes of thermal processing are defined. The experiments on thermal treatment of rail tests of rails were made directly after rolling. According to the results of the theoretical and laboratory data, the recommendations are developed for industrial introduction of technology of the differentiated hardening. The conducted industrial tests have shown high quality of rail production on all parameters of the specifications and technical documentation corresponding to the requirements.
