В настоящее время наблюдается рост спроса на дробильные
стальные шары, применяемые при измельчении руд и полезных ископаемых,
что обусловливает необходимость проведения научных исследований в
данной области. Особую значимость приобретает вопрос производства
дробильных стальных шаров методом прокатки. В настоящей статье
рассматриваются вопросы повышения производительности работы
специальных двухвалковых поперечно-винтовых станов горячей прокатки,
используемых при производстве таких шаров. Цель исследования
заключается в теоретическом обосновании факторов, способствующих
повышению производительности прокатного производства в реальных
условиях, а также в получении необходимых выводов на основе
практических экспериментов. В результате проведённого анализа
научно обоснованы ключевые параметры рабочих звеньев прокатного
стана посредством аналитических зависимостей. Кроме того, были
проанализированы основные параметры, влияющие на производительность
шаропрокатного стана. На основе анализа разработаны многозаходные
винтовые калиброванные валки, а также соответствующие направляющие линейки с усовершенствованной рабочей частью. Практические испытания,
основанные на результатах исследования, были проведены в производствен-
ных условиях шаропрокатного подразделения АО «Узметкомбинат» и
позволили получить значимые результаты.
The increasing demand for steel grinding balls, currently used in
the crushing of ores and minerals, necessitates scientific research in this field.
Consequently, obtaining steel grinding balls through the rolling method becomes
significant. This article examines ways to enhance the productivity of special
two-roll mills with transverse-screw rolling, employed in the production of steel
grinding balls via hot rolling. The research aims to create a solid understanding
of what factors can boost worker productivity in making steel grinding balls using
the rolling method, based on how production is set up, and to draw important
conclusions from real-world tests. As a result of the studies done, the important
settings for the main parts of the rolling mill have been backed up with scientific
reasoning through analytical relationships. We have also analyzed key parameters
related to enhancing the productivity of the ball-rolling mill. Based on the analysis
results, rolling rolls with multi-start screw calibers, used in the ball-rolling
process, have been manufactured, and corresponding guide rail designs have been
developed. We conducted practical tests under production conditions at the "Ball
Rolling Division" of the joint-stock company "Uzmetkombinat," which produced
significant results.
