Использование предразгона двигателя прокатной клети для уменьшения динамической нагрузки Маклакова Е.А. Южно-Уральский государственный университет (национальный исследовательский университет) г. Челябинск, Российская Федерация karyakina-katya@yandex.ru Аннотация. Представлено исследование влияния предразгона двигателя прокатной клети на динамическую нагрузку. Приведена кинематическая и функциональная схема электропривода прокатной клети толстолистового стана 5000 ОАО "Магнитогорский металлургический комбинат". Для анализа динамических и статических режимов четырехвалковой горизонтальной клети была реализована математическая модель системы в приложении Matlab/ Simulink. Построена экспериментальная зависимость перерегулирования от скорости ожидания металла. Ключевые слова: толстолистовой прокатный стан, ударная нагрузка, синхронный электропривод, перерегулирование, величина зазора.Abstract. In the article deals an influence of pre-acceleration of motor shaft on impact load. The kinematic and functional schemes of the electric drive of the rolling mill of OJSC "MMK" are shown. A mathematical model of horizontal stand mill was implemented for analyze the dynamic and static functions in the Matlab/Simulink. The experimental dependence of the overshoot on the metal waiting speed had been created.

“…Emergency downtime of rolling mills that are caused by the breakdowns of spindle connections is 12-15% of total downtime in consequence of failure of mechanical facilities. The breakdowns of elements of joints (bushes, fingers, blades and jaws) are generally minor part of failure quantity due to deterioration of effective area, however, as a rule it causes rather a long downtime of the mills [1]. The fundamental causes that determine the level of the percussion leads at the roll biting of the metal are the rolling speed, the temperature and the shape of the front end of the strip, beating of the elastic torque and angular gaps in the joints.…”

The paper considers issues of a mathematical model development of a “deformation zone - main electric drive” concerning hot plate mills. The dependence of the calculation of rolling torque on features of high deformation zone is given. Based on the obtained expressions, the structural diagram of the deformation zone model has been developed. The paper specifies the structure of the mathematical model for electric drive speed control system based on the known equations of synchronous motor. After the comparison of the transient processes of the electric drive coordinates and rolling settings obtained at the modeling and oscillography at the mill the conformity of the developed model to the studied object has been proved. The provided mathematical model is recommended to analyze the dynamic percussion leads that occurred at hot plate mill. The model obtained allows it to improve the reliability of the electromechanical system owing to the adaptation of the rolling schedule at the real-time operation mode.
