| 摘 要： | 利用大样电解、金相观测、扫描电镜(SEM)和电子探针(EPMA)等手段,对X70管线钢铸坯中夹杂物的数量、粒径、形貌及组分进行了研究.结果表明:X70管线钢铸坯中夹杂物数量较多,粒径较大,且多为复合夹杂.针对大型夹杂物中硫化物、氧化物、硅铝酸盐和钙铝酸盐复合夹杂的特点,分析了铸坯中夹杂物的主要来源.

| Abstract: | Utilizing the methods of sample-electrolysing,metallographic observation,SEM and EPMA,the quantity,dimension,morphologies and composition of non-metallic inclusions in X70 pipeline steel cast slab were investigated.It was suggested that there were larger amount of inclusions with larger diameter in the cast slab.Most of these inclusions were complex,such as sulfide,oxide,silicon aluminates and calcium aluminates inclusions.According to the characteristics of inclusions in the cast slab,the major sources of ... |
