发明名称 Process for handling powder green compacts, and rare earth metal-based magnet
摘要 In a process for handling green compacts made from a rare earth metal-based magnetic alloy powder by a press machine to slide, on a sintering support plate, the green compacts, the support plate used has a surface roughness degree Ra in a range of 0.6 to 47 mum. At a first step, the green compacts are disposed in a first position near a final transport position, and at a second step, the said green compacts disposed in the first position are slid on the sintering support plate and disposed in the final transport position. Thus, by using the support plate having a surface roughness degree in a particular range, the green compacts made from the rare earth metal-based magnetic alloy powder can be sintered without occurrence of the deposition of the green compacts to the support plate, the chipping of the green compacts and the like. In addition, the efficiency of operation of the press machine can be increased.
