| 摘 要： | 采用两种不同的生产工艺生产弹簧钢以控制氧化物夹杂的性质和尺寸分布。研究发现，钢中酸溶铝含量的高低并不影响弹簧钢的奥氏体晶粒度，但明显影响钢材中的非金属夹杂物尺寸分布，从而影响高强度弹簧钢的疲劳性能。

| Abstract: | In order to control the property and size distribution of oxide inclusions,two different processes to produce spring steel were used.It was found that the acid soluble aluminum content in the spring steel does not exert influence on the austenite grain size,but it obviously exerts influence on the size distribution of non metallic inclusions and fatigue property of hot rolled spring steel rods. |

| Keywords: | high strength spring steel inclusion size distribution inclusion control fatigue property |
