【Abstract】 Development of the vacuum strip-casting(SC) technology was summed up in view of the process and equipment for preparing h igh quality NdFeB permanent magnet,especially the mainstream technologies relevant to vacuum SC.It is suggested that the R&D of combining vacuum SC with the advanced technologies,such as hydrogen decrepitating(HD),jet mill (JM) and low-oxigen-process(LOP) will be the developmental trend of NdFeB production,as well as the large-capacity and multi-function vacuum strip casting furnace.更多还原
