摘要： PROBLEM TO BE SOLVED: To improve wear resistance and ductility of a rail by controlling the component of a steel, ratio of reaction force in a finish rolling process and a heat treatment condition after the finish rolling process to make a structure of a head part of the rail fine and control the hardness within a predetermined range.SOLUTION: The method is used to produce a pearlitic rail excellent in wear resistance and ductility by performing at least rough hot rolling and finish hot rolling to a rolling billet for the rail which comprises, by mass%, C: 0.65-1.20%, Si: 0.05-2.00%, Mn: 0.05-2.00%, and the balance being Fe and unavoidable impurities. The finish hot rolling is conducted at a temperature range where a rail head surface is in a temperature range of not higher than 900°C to not lower than Ar3 transformation point or Arcm transformation point to obtain a structure in which an amount of non-recrystallization austenite structure produced immediately after the rolling counts for not less than 40% and not more than 70% by an area ratio. Then, the rail head part surface after finish hot rolling is subjected to accelerated cooling to at least 550°C at a cooling rate of 2 to 30°C/sec within 150 sec after the completion of the finish rolling.
