In this paper, based on the chemical composition of U75V rail, the rare earth element Ce with contents of 0%, 0.002%, 0.004%, 0.006 and 0.008% was added into the rail respectively as well as the samples were prepared by such process as smelting in 25 kg induction furnace, ingot casting and rolling to explore the influences of Ce on the microstructure and corrosion performance of rail steel. In this experiment, the pearlite lamellar spacing of rail steel is affected by adding Ce element. With the addition of Ce element, the pearlite lamellar spacing is first decreased and then increased as well as reaches the minimum when adding 0.004% Ce and the corrosion resistance is also the best.
