低压转子锻件次表层缺陷的研究与预防

Research and Prevention of Subsurface Defects for Low Pressure Rotor Forgings

通过对30Cr2Ni4MoV低压转子锻件次表层缺陷的解剖分析和研究,确定缺陷性质,研究并制定预防措施,通过实施优化出钢前缓吹氩参数、严格控制炉渣碱度等措施,有效提高钢水纯净度,可以有效改善锻件质量,降低次表层缺陷带来的产品报废质量风险。

This paper analyzes the causes and nature of UT defects by comparing the production situation of the ring forgings of two heats, and puts forward the eon＇esponding improvement measures.
