Heat treatment of U76CrRE rail is simulated by using MMS-200 thermal simulated test machine. The influence of pearlite transformation temperature on its microstructure and hardness is obtained by microstructure observation and hardness testing analysis. And the results show that the lower transformation temperature, the shorter interlamellar spacing in pearlitic microstructure of U76CrRE rail is and the hardness is increasing. At 560 ℃, there is a small amount of martensitic structure in microstructure.
