摘　　要：通过现场试验研究了小转炉配精炼炉生产高纯净度弹簧钢的工艺 ,结果表明在 30min的精炼时间内 ,小转炉 +LF +CC可生产出平均w (O) =31× 10 -6,最低w (O) =2 7× 10 -6;平均w(S) =6 0× 10 -6,最低w (S) =4 0× 10 -6;平均w (N) =4 1× 10 -6,最低w (N ) =36× 10 -6的高纯净度 6The technology for producing high cleanliness 60Si2MnA spring steel has been studied in Xingjiang Bayi Steel CO.,Ltd.Results show that 60Si2MnA spring steel with average oxygen content 31×10 -6 and the lowest 27×10 -6 , average suphur content 60×10 -6 and the lowest 40×10 -6 , average nitrogen content 41×10 -6 and the lowest 36×10 -6 can be produced by small size LD+LF+CC process.
