在稀土钴永磁合金应用领域不断扩大的新情况下,由冶金部科技办、军工办联合主持分别于1980年12月18日至20日和12月23日至25日在北京有色金属研究总院、北京钢铁研究总院召开了“钙热还原法制取SmCox粉末新工艺”鉴定会和“稀土钴永磁合金”鉴定会。这两个鉴定会肯定了近几年来稀土钴永磁合金的研究成果以及推广应用的前景。北京有色金属研究总院用钙热还原法研制成功的烧结用SmCox(4.5≤x<5)粉末的
In the rare earth cobalt permanent magnetic alloy applications continue to expand under the new situation, the Ministry of Metallurgical Science and Technology Office, Military Office jointly presided over the December 18, 1980 to December 20 and December 23 to 25 in Beijing Nonferrous Metal Research Institute, Beijing Iron and Steel Research Institute held a “calcium calorie reduction process SmCox powder new technology” appraisal and “rare earth cobalt permanent magnet alloy” appraisal meeting. These two identification will confirm the research results of rare earth cobalt permanent magnetic alloys in recent years and promote the application prospects. Beijing Nonferrous Metal Research Institute developed by the method of calorific reduction SmCox sintering (4.5 ≤ x <5) powder
