【 摘 要 】

On the pilot plant the experiments in the differentiated heat treatment by air using the heat of rolling heating of rails produced from steel E76HF with three chemical compositions comprising various contents of chromium, manganese and silicon were carried out. The effect of heat treatment parameters on the structure and properties of rails was examined. According to the results of experiments the rational chemical composition was determined, as well as the heat treatment modes recommended for a mass production of differentially thermo-strengthened rails of DT350 category.
