【 摘 要 】

At the present time in conditions of high intensity use of the railways of great importance paid to longer service life the railroad tracks, elements turnout in particular crosspieces. The main element of the railway track turnouts are carrying out a change of direction of movement of trains. Many translations have exhausted their time and are obsolete. From is technical condition turnout's largely dependent reliability of rail transport. Turnouts are the most complicated structure in the railway. Individual elements of the railway line - the spider who perceives high impact loads. Crossings should have sufficient strength and wear resistance because undergo complex dynamic loads. High dynamic impact and wear areas are also experiencing the antennae, which are located near the cores. The basic technological aspects to improve the characteristics steel by modifying. The technology of producing high-manganese steel modified special modifier to improve the structural strength of receiving the item. As a result of a series of experimental heats received the samples that were subjected to mechanical testing. Structural studies have shown improvements steel microstructure as well as its mechanical properties.
