Abstract

Efficiency of using UIC60 type rails instead of Р65 type on Ukrainian railways is shown. Steel saving is 8.8 tons per 1 km of track. Technological advancement of steel killing is investigated at JSC “Iron & Steel Works “Azovstal” which enabled to satisfy requirements of category B according to DSTU 4344:2004 regarding to the length of nonmetallic inclusion lines for М76ФБ steel grade. Developed and implemented industrial technology of hardening inner edges of М76Т steel rail head of Р65 type ensures reduction of inner wear by 40%.
