我省铸造情报网于七五年二月廿五日至廿六日在佛山市召开了钇基重稀土球铁科研情况交流会。出席会议的有省铸造情报网核心小组单位、郑州机械所、冶金部有色金属研究院、省工交办、省科技局等29个单位、43人。会上,佛山水泵厂代表介绍了一年多来在冶金部有色院的协助下,该厂对钇基重稀土球化剂制造球铁应用于实际生产的试验研究情况,并参观了开炉现场。冶金部有色院的同志介绍了钇基重稀土的资源和冶炼过程及其用作球化剂的情况。代表们经过讨论,初步认为:钇基重稀土球化剂是应用我国矿源试验成功的新型球化剂,它比目前广泛使用的镁系球化剂具有许多优越性。初步试验与使用说明,它球化处理
The Provincial Foundry Intelligence Network held a seminar on the research and development of the ruthenium-heavy rare earth ductile iron research in Foshan from February 25th to June 26th. Attending the meeting were 29 units and 43 people, including the Provincial Foundry Intelligence Network Core Team Unit, Zhengzhou Machinery Institute, the Ministry of Metallurgy Nonferrous Metals Research Institute, the Provincial Bureau of Industry and Technology, and the Provincial Science and Technology Bureau. At the meeting, the representative of the Foshan Water Pump Factory introduced the experimental research on the application of Nb-based heavy rare earth nodulizer to the production of ductile iron under the assistance of the Nonferrous Metals Institute of the Ministry of Metallurgical Industry over the past year and visited the site of the opening of the furnace. . Comrades from the Nonferrous Metals Institute of the Ministry of Metallurgy introduced the resources and smelting process of cerium-based heavy rare earths and their use as spheroidizing agents. After discussions, the delegates initially believed that: Ruthenium-based heavy rare earth nodulizer is a new type of nodulizer successfully applied in China’s ore source test, and it has many advantages over the currently widely used magnesium-based nodulizers. Preliminary tests and instructions for use, it spheroidizes
