Abstract

本发明提供一种高均匀性铝钼铁中间合金的制备装置及方法,属于合金材料技术领域。所述装置包含真空铝热炉以及其内部的石墨熔池和水冷铜坩埚,石墨熔池在上,水冷铜坩埚在下,石墨熔池底面为带孔镁砖,带孔镁砖内部设置电热丝。所述方法为用铝片将带孔镁砖的孔堵住,在石墨熔池内部布置阵列铁丝,然后将原料混合均匀加入;抽真空,同时加热带孔镁砖,水冷铜坩埚通冷凝水,到达点火条件后,通过阵列铁丝实现物料点火,进行铝热反应,得到的合金溶液通过孔流入水冷铜坩埚,冷却得最终铝钼铁合金,其品位如下:钼50~65 wt%、铁20~35 wt%、铝余量,氧≤0.1 wt%、硅≤0.1 wt%、氮≤0.01 wt%,本发明解决了传统TC24、TC28用含铁中间合金均匀性差、气体杂质含量高的问题。
