Abstract
Способ термомеханической обработки сварных стыков рельсов, в котором нагревают сечение в зоне сварного шва до (850-900)°C и принудительно охлаждают головку с одновременным охлаждением шейки и подошвы естественным путем на воздухе, отличающийся тем, что быстро охлаждают сварной шов до температуры Мн°C, в диапазоне температур (Мн-Ткомн)°C производят упрочнение дробью 0,8-1,5 мм.A method of thermomechanical processing of welded joints of rails in which the section in the weld zone is heated to (850-900) ° C and the head is forcibly cooled while the neck and sole are cooled naturally in air, characterized in that the weld is quickly cooled to a temperature of M ° C, in the temperature range (Mn-Tkomn) ° C hardening is carried out with a fraction of 0.8-1.5 mm.
