在近代工业生产中,由于铝箔具有优良的综合性能,因而被广泛用于包装行业、电器产品、日用品,建筑材料及卷烟生产等各个方面。国内市场的需求量每年在1.5万吨以上,提高铝箔质量和生产效率已成为铝箔轧机的发展方向,液压伺服系统的应用从根本上解决了轧机高速、高精度和高效率的问题,使轧制后的铝箔厚度达到0.007mm,轧制速度高达1200m/min,液压轧制力达到4000kN,由电液伺服系统保证工作压力和辊缝恒定,轧机工作的稳定性一方面取决于制定正确的工艺流程,另一方面取决于电液伺服系统的动态性能。本文针对具体的铝箔轧机,建立了电液压力控制系统的数学模型和传递函数,并从理论与实践的结合上,分析了影响系统稳定工作的各个参数之间的关系,提出了保证系统稳定工作的方案和措施。
In modern industrial production, aluminum foil is widely used in the packaging industry, electrical appliances, daily necessities, building materials and cigarette production due to its excellent overall performance. The demand of the domestic market is more than 15,000 tons per year, improving the aluminum foil quality and production efficiency has become the development direction of the aluminum foil rolling mill. The application of the hydraulic servo system fundamentally solves the problems of high speed, high precision and high efficiency of the rolling mill, After the aluminum foil thickness of 0.007mm, the rolling speed of up to 1200m / min, hydraulic rolling force of 4000kN, electro-hydraulic servo system to ensure that the work pressure and roll gap constant, on the one hand the stability of the mill work to develop the correct process , On the other hand depends on the dynamic performance of electro-hydraulic servo system. In this paper, the mathematical model and transfer function of the electro-hydraulic pressure control system are established for a specific aluminum foil mill. Based on the combination of theory and practice, the relationship between the various parameters that affect the stability of the system is analyzed. Programs and measures.
