The effects of slag containing rare earth oxide under on non-metallic inclusions and tensile property during of the AF-3 steel by ESR were experimentally investigated. Specimens were taken at the electrode and each remelting ingot for analyzing the compositions, dimensions, and types of non-metallic inclusions. After hot rolling and sensitization treatment, electronic universal testing machine was employed to investigate normal and hot tensile performance. The results show that under simple nitrogen atmosphere combined with reduction treatment of slag containing rare earth oxide, oxygen content can be reduced from 76 ppm (electrode) to 29 ppm, 42 ppm and 51 ppm under different remelting conditions. Compared with the electrode, the content of the non-metallic inclusions was largely reduced. The results of tensile experiments indicate that the ingot under nitrogen atmosphere combined with slag reduction treatment has a better tensile performance.
