摘　　要：高压锅炉管的使用环境恶劣,对于圆管坯夹杂物的要求非常苛刻。实际生产12Cr1MoVG的过程中,时常出现夹杂物超标问题。通过改进转炉终点碳含量控制目标、优化精炼渣系及窄成分控制等措施,解决了夹杂物超标问题。The service environment of high-pressure boiler tube is harsh,so the requirements for inclusions of tube bloom are very strict. In the actual production process of 12 Cr1 MoVG,the inclusions are often over proof,which is solved by such measures as improving the control target of end-point carbon content in converter,optimizing refining slag system and narrow component control.
