【摘要】 液压辊缝控制系统是冷连轧机组控制带钢厚度精度的关键环节,液压压下系统是液压辊缝控制的最重要的组成部分。通过对某冷轧厂四辊冷带轧机液压压下系统的研究,对工作在位置控制方式下的液压压下系统建立了数学模型,并对系统进行了时域和频域的分析,掌握了系统的实际动态特性。为以后系统的优化设计和控制系统的性能研究打下了基础。更多还原

【Abstract】 Hydraulic gap control system is the key part of accuracy for stripe gauge control of tandem cold rolling mill. Hydraulic screw down system is the most important part of hydraulic roll gap control. Through researched on hydraulic screw down system of a cold rolling sheet plant the article, establishes mathematical models of every part of hydraulic screw down under position control . Time domain and frequency domain characteristics of the system are analyzed. And the practical dynamic characteristic performance is grasped. A foundation is laid down for optimal design of the system.更多还原
