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.

Japan-Tefeno-Shikano methodis considered as an effective method of improving the qualities of heavy forgings. But the traditional JTS processing is complex, and it causes material damage of forging surface. So a new method is proposed, which requires only one-dimensional temperature gradient and the flat anvils to avoid the disadvantages mentioned above.
在大锻件的锻造过程中,为了锻合缺陷,提高锻件内部质量,采用中心压实法可以起到较好的效果,但是由于传统中心压实法锻造的操作复杂,工况较差,而且锻件表面容易产生压伤和折叠等问题,所以提出一种新的中心压实法―一维温差中心压实法,即只对锻件上下表面强制冷却,建立一维的不均匀温度场,采用平砧进行锻造,从而避免上述问题。
