≤0.025P)was produced by the flow sheet: hot metal pretreatment- 120t converter blow melting- LF refining- 4.8t ingot ca- sting- 800 mill rolling for hot forging at Benxi Steel. The nitrogen content in steel was trimmed by adding N-Mn alloy with argon stiring during LF refining
after refining feeding Si-Ca wire. The analysis results showed that hydrogen content in steel was(0.6~1)×10
