Abstract:The large-size inclusions in rails can endanger the safety of trains. the large-size inclusions cases of rails in China in recent years and the corresponding chemical composition had been analyzed by using SEM. The result shows that the shape and character of the inclusions in rails had been significantly changed after the equipment transformation and the republication of the new railway industrial standard in China. Large-size external inclusions are mostly introduced by casting system. Refractory and mould fluxes in rails had a great impact on the fatigue property, of which the rails factories need to attract enough attention.
