    摘要:

    简述了用于制作Ni-MH电池的稀土贮氢合金的生产方法。选用陶瓷坩埚和水冷坩埚感应熔炼法分别制取了多元稀土贮氢合金锭,指出选用合适的陶瓷坩埚,带入熔体中的杂质均<0.1%。若采用水冷坩埚可得到一次熔炼成份均匀、准确且不被坩埚污染的合金熔锭。文中还介绍了冷坩埚感应熔炼的工艺特点及所炼贮氢合金熔锭的分析结果。

    Abstract:

    The method of production to prepare rare-earth hydrogen-stored alloys intended to be used for producing Ni-MH batteries is stated in brief. Multi-element rare-earth hydrogen-stored alloy ingots have been obtaineal by induction melting method of using ceramic crucible and water-cooling crucible, respectively. It is indicated that the concentration of impurity carried into the melt can be limited within some hundreds of ppm. By using a suitable water-cooling ceramic crucible, we can obtain the uncontaminated alloy ingots with homogenous and accurate composition. The process characteristics. of induction melting method with cold crucible and the result analysis of hydrogen stored alloy ingots obtained are introduced as well.
