Mount restrictor bar into the restrictor bar groove of upper die , mount adjusting bolt for restrictor bar into the bolt hole in the restrictor bar , then mount lower press block , upper press block 在上模节流棒槽内装入节流棒，将节流棒调节螺栓装配进节流棒的螺丝孔中，再装配上压块。
The chemical reaction control of cuo - al system has been studied . the results show that the chemical reaction is more stable when cupric oxide and aluminium is put respectively into molten copper 在此基础上，实验研究了cuo ? al体系的化学反应控制，得出了采用cuo和al分别加入法比压块加入法会使反应进行的更加平稳。
Different from the general method of preparing zro2 - ni cermets in which zr02 and nio powder are mixed together , pressed , sintered and reduced , we adopt a novel coordination - gel method to prepare zro2 - ni nanocrystalline composite powder in this study 与传统的用ysz粉末和nio粉末混和、压块烧结、还原制备ysz - ni金属陶瓷不同，本文采用一种新的络合-凝胶法。
On the base of analyzing the development of control system for synthetic rubber press internationally , and combining the development status quo of applied research of reliability engineering of hydraulic systems , to overcome the design limitations of traditional control system for synthetic rubber press and such faults as high energy - consume , long process period and low reliability in the pressing process of synthetic rubber in the post - treatment product line , brand - new design and reliability research are to be carried out for the new control system 通过对目前国内外合成橡胶压块机控制系统发展水平的分析，结合可靠性工程在液压系统中应用研究的发展现状，针对国内合成橡胶后处理生产线上传统橡胶压块机控制系统的设计缺陷及橡胶压制过程中能耗高、工艺周期长、可靠性差等故障现象，对橡胶压块机控制系统进行全新设计和可靠性研究。
