Sažetak

Three electroslag remelting heats were carried out by using a 1-ton argon atmosphere ESR furnace under three kinds of slag containing different Ce₂O₃ content. Specimens were taken at electrode and each ingot for analyzing the inclusions by scanning electron microscope - energy dispersive spectrometer (SEM-EDS). After heat treatment, the tensile and impact of each steel product was measured to study the effect of Ce content on steel performance.The results show that the non-metallic inclusions content was largely reduced in each ingot compared with that in electrode, and the ingot containing 0,05 % Ce has the best steel cleanliness and performance, while the ingot containing 0,13 % Ce has the worst steel cleanliness and performance.
