Abstract

Abstract: The manufacturing process of low O/N content K417G Ni-based superalloy is introduced. The degassing treatment methods at different stages of alloy preparation are emphatically discussed, and the measures to avoid gas introduction in different process links are described. The gas of surface adsorption on material is removed as much as possible before melting. During melting, the power is set from 300kW to 750kW, and the single weight of charging is limited to 500kg to reduce the content of O and N to 0.0018% and 0.0014% respectively. During the refining period, the temperature of molten bath is kept at 1582℃, and the reaction of deoxidization by carbon is used to reduce the content of O and N to 0.0006% and 0.0002% respectively after refining for 80min. The rare earth elements are added to molten bath as deoxidizer after refining to reduce the content of O to 0.0003%. At last, the production of low O/N content Ni-based superalloy is producted successfully.

Key words: superalloy, K417G, vacuum induction melting, degassing treatment
