石钢公司采取“60t转炉冶炼→60 t LF炉精炼→60 tVD炉精炼→连铸机（150 mm ×150 mm）→轧钢厂小型棒材线（连轧）轧制”工艺路线，通过化学成分、非金属夹杂物和表面质量控制，成功开发出3130和20 Ni2 MoA钢K级和KD级防腐抽油杆用钢。经生产检验和用户使用，抽油杆钢材的各项指标完全符合用户协议要求。
石鋼公司採取“60t轉爐冶煉→60 t LF爐精煉→60 tVD爐精煉→連鑄機（150 mm ×150 mm）→軋鋼廠小型棒材線（連軋）軋製”工藝路線，通過化學成分、非金屬夾雜物和錶麵質量控製，成功開髮齣3130和20 Ni2 MoA鋼K級和KD級防腐抽油桿用鋼。經生產檢驗和用戶使用，抽油桿鋼材的各項指標完全符閤用戶協議要求。
석강공사채취“60t전로야련→60 t LF로정련→60 tVD로정련→련주궤（150 mm ×150 mm）→알강엄소형봉재선（련알）알제”공예로선，통과화학성분、비금속협잡물화표면질량공제，성공개발출3130화20 Ni2 MoA강K급화KD급방부추유간용강。경생산검험화용호사용，추유간강재적각항지표완전부합용호협의요구。
In Shi Steel, 3130 and 20Ni2MoA of the K-level and KD-level anti-corrosion sucker rob steel are successfully developed with process of"60-ton converter smelting plus 60-ton LF furnace refining plus 60-ton VD furnace refining plus caster (150 mm ×150 mm) plus small-section bar ( continuous rolling) line", and with control for chemical composition, non-metal inclusion and surface quality.With production detection and user's application, it is proved fully meet the demand of customers in its various indexes.
