| Abstract: | Surface air holes on 1Cr21Ni5Ti ESR ingots produced according to Non-vacuum induction meltingfurnace＋ electroslag furnace was investigated and analyzed in this paper. It was found that reducing hydrogen contentin ESR ingots was the key factor to control the formation of air holes in ESR ingots. The appearance of air holes onESR ingots was restrained effectively by relevant measures in subsequent production. |
