Effect of Current on Segregation and Inclusions Characteristics of Dual Alloy Ingot Processed by Electroslag Remelting

Abstract: Three dual alloy ingots were processed by electroslag remelting with 1500 A, 1800 A and 2100 A. The compositions and inclusions of ingots were analyzed by means of various analytical techniques. The results show that the segregation becomes severer with the increase of current. With the current increasing, the proportion of inclusions with large size, the T.[O] and sulfur content in the ingot increase, showing a worse cleanliness due to the severer electrode surface oxidation and shorter interaction time between slag pool and film of molten steel at the electrode tip. The single (Mn,Cr) S inclusion can precipitate in transition zone of each ingot and NiCrMoV zone of ingot with 1800 A and 2100 A due to higher sulfur content and the solute segregation during solidification. The ingot processed by ESR with 1500 A performed a balanced quality.
