| 摘 要： | 对于稀土储氢合金冶炼废渣粉,采用水热酸溶-还原扩散-电弧熔炼的方法回收稀土氧化物和稀土镍钴合金。废渣粉首先用水热酸溶法分离其中的部分稀土氧化物,得到的合金富集物配加金属钙粒用还原扩散法将其中剩余的稀土氧化物转化为AB5型合金,还原扩散得到的合金粉采用电弧熔炼得到稀土镍钴合金。回收的合金杂质含量低,可作为基础原料用于熔炼AB5型稀土储氢合金,实现了稀土储氢合金冶炼废渣的循环利用。

| Abstract: | Recycling RE-Ni-Co alloy from waste residue powers of RE hydrogen storage alloy melting was researched by the method of water bathing and acid dissolving –reduction diffusion –arc melting.Firstly,rare earth oxides were separated partly from waste residue powders in the process of water bathing and acid dissolving,and alloy enrichment was obtained.Then,the rest rare-earth oxides were reduced into AB5 type alloy by adding calcium granules into alloy enrichment in the process of reduction-diffusion,and alloy powers were obtained.Finally,RE-Ni-Co alloy was obtained from alloy powers in the process of arc melting.RE-Ni-Co alloy with low impurity can be used as basic material of AB5 type hydrogen storage alloy. |
