Investigation into the influence of speed characteristics of compaction on the quality of wares made of uranium dioxide

Investigation into the influence of pushing-out regulation during the formation of powders on the quality of uranium dioxide wares

“…(vi) A principled design solution on the develop ment of hydromechanical press automate [6] is devel oped based on the results of the complex of studies [1,2]. This solution ensures the implementation of the optimal regulation of formation for obtaining defect free compacts.…”

“…In previous publications [1,2], a profile of the internal cavity of the matrices for the formation of articles [1] was substantiated and it was revealed that the nonuniform character of com pacting (interrupted, stepped) can determine the appearance of cracks [2], while a uniform character promotes a decrease in the amount of rejected articles and forms prerequisites for an increase in compacting productivity. However, under definite formation modes with the subsequent pushing out of the pellets (compacts), cracks leading to cleavages from the side of the pushing out (lower) punch are formed on their ends (Fig.…”
