In the dehydrogenation process of HD process, the temperature set at 580℃ and pressure set at 100Pa is a perfect parameter, it can make the magnet to have high magnetic performance. In the HDDR process experiment, the paper contrast four HDDR process such as C-HDDR V-HDDR V-HD-S-DR and d-HDDR by the anisotropy and magnetic performance of ternary NdFeB magnetic material. The results show that adjusting the parameter of the d-HDDR process can make the anisotropy and magnetic performance of ternary NdFeB magnetic powders to catch up with the hexahydric NdFeBCoZrGa magnetic powders. At the end the paper discusses the betterment of the equipment which produces ternary NdFeB magnetic with the d-HDDR process.

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.
