Выявлено влияние многоуровневой литниковой системы на эффективность заполнения расплавом полости формы облицованных кокилей на качество кристаллизации крупных мелющих шаров, а также на повышение выхода годного литья. Исследовано влияние толщины облицовочного слоя на кристаллизацию крупных мелющих шаров. Исследовано влияние модификаторов с содержанием бария, магния и церия на физико-механические характеристики мелющих шаров и отдельно отлитых образцов. Разработана технология устранения усадочных раковин в литых мелющих шарах путем усиления направленной кристаллизации за счет частичной замены облицовочного слоя термостойким водным покрытием. Предложено оборудование для массового производства высококачественных крупных мелющих шаров, разработанное ОАО «БЕЛНИИЛИТ» и конкурентное мировым аналогам.</p></abstract><trans-abstract xml:lang="en"><p>The article presents a number of experimental and research works on the development of parameters of the casting technology of grinding balls by casting in a lined coquille (chill mould) with a vertical connector. The influence of a multi-level gating system on the efficiency of filling the mold cavity of lined coquilles with melt, on the quality of crystallization of large grinding balls, as well as on increasing the output of suitable casting was revealed. The influence of the thickness of the facing layer on the crystallization of large grinding balls is studied. The effect of modifiers containing barium, magnesium and cerium on the physical and mechanical characteristics of grinding balls and separately cast samples is investigated. Technology has been developed to eliminate contraction cavity in cast grinding balls by enhancing direct crystallization by partially replacing the facing layer with a heat-resistant water coating. The equipment for large-lot production of high-quality large grinding balls developed by OJSC “BELNIILIT” and competitive to world analogs is proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>литые мелющие шары</kwd><kwd>литье в облицованный кокиль</kwd><kwd>литниковые системы</kwd><kwd>выход годного</kwd><kwd>направленная кристаллизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cast grinding balls</kwd><kwd>casting in lined coquille</kwd><kwd>gating systems</kwd><kwd>output of suitable</kwd><kwd>directional crystallization</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
