[0030] Example 1:
[0031] Preparation of low-cost high-performance sintered NdFeB permanent magnet materials: The preparation process of the low-cost high-performance sintered NdFeB permanent magnet material includes the following steps:
[0032] (1) ingredients: The one Yceco5 powder is ingredient according to the following atoms, Y 12.50 CE 4.17 CO 77.83 Mo 2.5 GA 3 ;
[0033] (2) The ZDL-600 vacuum tape furnace produced by Ai Weike Vacuum Equipment Co., Ltd., the melting strip furnace is started to start the drying, and the bake power is set to 200KW, the bake is 30 min. When the vacuum is less than 5Pa, the charge is simultaneously molten at the same time, and the metal is all melted to 500 kW refine 5 min, when the temperature reaches 1430-1450 ° C, then regulate the water-free copper roller speed 45 rpm, control The inlet temperature starts to cast a sheet alloy at 10-15 ° C; the prepared sheet alloy thickness is controlled at 0.15-0.25 mm;
[0034] (3) Prave the tape sheet...
