Behavior of non-metallic inclusions in centrifugal induction electroslag castings

摘要

In order to known the behavior of non-metallic inclusion in centrifugal induction electroslag castings(CIESC), non-metallic inclusions in 5CrMnMo and 4Cr5MosiV1 were qualitatively and quantitative analyzed. The largest size of inclusions in the casting and the thermodynamic possibility of TiN precipitation in steel were also calculated. The results show that sulfide inclusions are evenly distribute and the content is low. The amount of oxide inclusions in CIESC 4Cr5MoSiV1 steel is close to the ESR steel and lower than that in the EFA steel, and there are some differences along radial direction.
