Study on the modifiion of inclusions by Ca treatment in GCr18Mo bearing steel …

14/8/2019· The effect of Ca treatment on the modifiion of inclusions in Al-killed GCr18Mo bearing steel was studied and a thermodynamic and kinetic model was established. The experimental results showed that oxygen content in the steel could be reduced from 120 μg/g to the range 5.5–21.6 μg/g by Al-Ca complex deoxidization at 1 873 K. An appropriate increase …
