摘　　要：采用喂线法对蠕墨铸铁进行蠕化及孕育处理,分析了纳米SiC、微米SiC,以及纳米SiC含量(质量分数)为1%、10%、20%的复合纳米SiC孕育线对蠕墨铸铁的孕育效果。试验结果表明:复合纳米SiC孕育剂的孕育效果优于纯纳米SiC和纯微米SiC孕育剂,当加入量为0.05%时,含10%纳米碳化硅的复合纳米碳化硅对蠕墨铸铁的孕育效果最佳。The cored wire technology was used to inoculate the vermicular graphite cast iron.The effects of pure nano-SiC,pure micron-SiC and the composite nano-SiC inoculants with the contents of 1%,10%and 20% nano-SiC particles on the inoculation ofvermicular graphite cast iron were analyzed.The experimental results show that the inoculation effect of the composite nano-SiC inoculants is better than that of the pure nano-SiC or pure micron-SiC inoculant.With the addition of 0.05%inoculant,the composite nano-SiC inoculant containing 10wt.%nano-SiC particles has the best inoculation effect.
