| 摘 要： | 采用冲入法和喂线法两种球化处理工艺生产QT600-3凸轮轴,对比其成分、组织和性能,结果表明：用喂线法生产的铸件,w（S残）量达到双零级、w（Mg残）量的波动亦小,且球化效果好（石墨球数量多、尺寸小、圆整度高、球化率高）,力学性能良好稳定。

| Abstract: | Nodular iron camshafts of QT600-3 grade were produced with pour-over nodularizing process and cored wire injection process, their chemical composations, microstructures and properties were compared. The result showed that, for the nodular iron produced with cored wire injection process, the residual S content was relatively lower reaching the order of magnitude of 10-5, fluctuation range of the residual Mg content was also narrow; nodularity and nodule count of castings was relatively higher, graphite size ... |
