夹杂物造成SWRM17拉拔断裂的分析
|
摘要
针对SWRM17线材在拉拔过程中发生断裂质量问题,对断口进行电镜能谱检测分析,对断裂钢丝进行金相组织、非金属夹杂物检测分析,分析表明该质量问题是由于夹杂物造成的拉拔断裂缺陷.通过分析拉拔断裂原因、形成过程和机理,对工艺改进起到指导作用.
According to the fracture quality problems of wire WRM17 occurred in drawing process,the electron microscope energy spectrum analysis,microstructure of wire fracture,non metallic inclusion detection and analysis are made on the fractures. The analysis shows that the quality problems are caused by the drawing breakage defects resulted in the inclusions. Through the analysis of the formation process and mechanism of drawing fracture causes,it gives the instruction to the process improvement.
