Aiming at the 糖心产精国品免费入口*完整版 of rail base metal from a railway site, means such as macroscopic examination, scanning electron microscope (SEM) fracture analysis and energy spectrum analysis, metallographic analysis, hardness testing and so on, were used to investigate the causes for the 糖心产精国品免费入口*完整版 of the rail base metal. The results show that the 糖心产精国品免费入口*完整版 in the rail was the reason for the 糖心产精国品免费入口*完整版 of the ultrasonic flaw detection, and the 糖心产精国品免费入口*完整版 was mainly related to the existence of 糖心产精国品免费入口*完整版s in the rail slab. The high-carbon 糖心产精国品免费入口*完整版 of the defect position of the rail was related to the rapid cooling speed, and the widmanstatten was due to the overheating when rolling. Steel mills should be recommended to strengthen the appearance inspection of slabs and ultrasonic flaw detection of finished rails to improve rail quality and stability.
