对电磁纯铁热轧线材进行了低倍观察,对线材中的夹杂物进行了高倍金相、扫描电镜(SEM)和能谱分析(EDS)。结果表明,钢中夹杂物是单一的Al2O3夹杂,大部分夹杂物呈点、线状分布在线材横断面的1/4处,并沿纵向延伸。根据该钢种夹杂物的来源,提出了生产过程中减少夹杂物的3个关键措施。 Electromagnetic pure iron hot-rolled wire rod was observed at low magnification, the inclusions in the wire were analyzed by high magnification, scanning electron microscopy (SEM) and energy spectrum analysis (EDS). The results show that the inclusions in steel are single Al2O3 inclusions, most inclusions are spots, which are linearly distributed at 1/4 of the cross section of the wire and extend longitudinally. According to the source of inclusions in steel, three key measures to reduce inclusions in the production process are proposed.
