При производстве стальных помольных шаров, применяемых для дробления руд и минералов, важным является вопрос повышения производительности и повышения износостойкости шаров. Большое значение при этом имеет дальнейшее совершенствование рабочего процесса многозаходных шаропрокатных валков и направляющих линий шаропрокатных станов, применяемых при прокатке шаров, а также разработка ресурсосберегающих технологий. Очень важно применять энергоэффективные и ресурсосберегающие технологии в процессе производства шаров методом прокатки. С целью повышения производительности при прокатке шаров наиболее удобным способом решения поставленной задачи является вопрос о создании кулачковых механизмов, режущих многозаходные шаропрокатные валки, применяемые при прокатке шаров, и разработке новой конструкции направляющей линии шаропрокатного стана. При этом одной из необходимых задач является проектирование и разработка математических моделей для создания новых конструкций механизмов, применяемых при прокатке шаров. В данной статье представлены решения по вопросу использования многозаходных шаропрокатных валков с целью повышения производительности стальных помольных шаров методом горячей прокатки, которые получены в результате теоретических научных исследований и практических испытаний.

Increasing the productivity of the output and improving the wear resistance of steel grinding balls used for grinding of ores and minerals is an important task. In this regard, further improvement of the operational process of multi-pass ball rolling rolls and linear guides used in rolling of balls, as well as the development of resourcesaving technologies, is being of great significance. It is crucial to utilize energy- and resource-efficient technologies in producing of balls by rolling. In order to enhance productivity of rolling of balls, creating cam mechanisms for cutting multi-pass ball rolling rolls and developing a new design for the linear guides of the ball rolling mill are regarded to be effective approaches to address the problem. In this regard, developing of mathematical models for creating new designs of mechanisms used in rolling balls appears to be one of the urgent tasks. This article presents theoretical solutions based on scientific research and analyses of findings from practical tests on the use of multi-pass ball rolling rolls in view of raising the productivity of steel grinding balls by means of hot rolling. Moreover, the solution to the studied problem was determined by using six-pass ball rolling rolls for rolling steel grinding balls with a diameter of 50mm as well as by creating a new design for ball rolling mill linear guides.
