| 摘 要： | 采用多种方法对酒钢72A钢中非金属夹杂物进行了调查，对夹杂物的类型，来源，数量及尺寸进行了讨论，实验证明，铸坯中夹杂物有60%外来杂夹物，40%为脱氧产物，引起线材拔脆断的主要原因是外来大颗粒脆性夹杂，而控制好脱氧产物和外来杂夹物的组成，形貌，大小及分布，是解决线材拉拔脆断的关键。

| 关 键 词： | 72A钢 非金属夹杂物 线材 拉拔脆断 外来夹杂物 高碳钢 拉拔性能 |

| Abstract: | Non-metallic inclusions of 72A Steel investigated invest using multi-measurements in Jiuquan Group. The amount, type, source, composition and distribution of the inclusions were discussed. The results show that more than 60% of inclusions in billet come from exotic inclusions, and 40% of inclusions in billet origin from oxides. The main reason of wire-breaking is large exotic inclusions. It is important to control the composition, shape, size and distribution of these endogenous and exotic inclusions. |
