一.前言 目前生产铝锰合金材用的铝锰中间合金,多采用对掺法,不仅工艺过程较多,劳动强度大,锰的回收率低,生产成本较高,而且合金成份不易控制均匀。1983年,东北工学院赵恒先等首先对用电解法制取铝锰合金作了研究,并成功地在实验室里制取了含锰0.18～1.16％的铝锰合金。1985年10月至1986年7月,我厂在实验室研究的基础上进 I. Introduction At present, the production of aluminum-manganese alloy aluminum-manganese alloy master alloy, the use of mixed method, not only more process, labor-intensive, low recovery rate of manganese, high production costs, and the alloy composition is not easy to control. In 1983, Zhao Hengxian of Northeast Institute of Technology and other first made electrolytic manganese aluminum alloy was studied and successfully prepared in the laboratory 0.18 ~ 1.16% manganese aluminum-manganese alloy. October 1985 to July 1986, I plant on the basis of laboratory research
