| 摘 要： | 研究了铝、钒、氮等微量元素对LZW车辆钢奥氏体晶粒度粒度的影响。研究结果明：为保证LZW车轴钢坯奥氏体晶粒度符合标准要求，应将钢中酸溶铝控制在适当含量范围，钢中加入微量钒可明显细化奥氏体晶粒，提高奥氏体晶粒粗化温度，转炉炼LZW车辆钢在高真空度下时间脱气处理对奥氏体晶粒度不利。

| Abstract: | Effect of micro alloying element Al,V,N on the grain size of LZW axletree steel have been investigated in this paper The results indicate that the proper range of acid soluble Al content should be controlled to satisfy the grain size requirement The addition of micro alloying V into steel refines grain and increases grain coarseningtemperature Treat ment in high vacuum condition for long time is harmful to grain size of LZW axletree steel melted with LD |
