Abstract

本发明公开了一种铝硅合金复合孕育剂及其制备方法，铝硅合金及其复合孕育剂的质量百分含量：硅6.0％～12.0％；稀土Y 0.1％～0.5％；金属Ni 0.5％～2.0％；余量为铝。将工业纯铝在790℃～820℃温度下加热至全部熔化后保温使熔体温度均匀，然后将200℃～450℃预热后的小块状工业结晶硅加入到铝熔体中，采用机械搅拌使结晶硅全部熔解到铝熔体中，然后熔体降温到710℃～730℃温度下保温10～30min，制备了成分均匀的Al-Si合金熔体；随后通入氩气进行精炼除渣除气，扒渣后浇入金属铸型，制得铝硅合金；将制备的铝硅重新熔化后，先后加入Al-Y和Al-Ni中间合金获得稀土Y和Ni复合孕育的铝硅合金。本发明的有益效果是制备方法简单易操作，复合孕育效果显著，组织稳定。
