摘　　要：为降低硅镇静钢全氧含量,采取优化转炉高拉碳工艺、开发转炉出钢碳脱氧工艺、开发硅镇静钢脱氧用渣料、优化LF精炼渣系和连铸机保护浇注等措施,实现了硅镇静钢成品W([TO])≤35×10^(-6)。In order to reduce the total oxygen content of silicon killed steel,measures such as optimizing the converter high carbon drawing process,developing the converter tapping carbon deoxidation process,developing the slag for deoxidation of silicon killed steel,optimizing the LF refining slag system,and protecting casting by continuous casting machines have been taken to achieve a silicon killed steel product W([TO])≤35×10^(-6).

关 键 词：硅镇静钢 高拉碳 全氧
