摘要

连退机组张力波动是影响其稳定运行与产品质量的关键因素。本文针对该问题，从设备、工艺、控制及材料维度剖析了张力波动的深层机理。分析表明，设备精度不足、工艺参数失调、控制系统响应滞后及材料性能波动是主要诱因。在此基础上，探讨了控制系统的响应机制与反馈策略，并指出了当前存在的优化空间。结合生产数据与工程实践，提出了优化控制模型以提升动态补偿能力，升级自动化系统以提高响应速度，并改进关键部件性能以增强设备基础稳定性。这些针对性措施旨在有效抑制张力波动，降低断带风险，为连退机组实现高效、稳定运行提供理论支撑与技术参考。

Abstract

Tension fluctuations in continuous rolling mills are critical factors affecting both operational stability and product quality. This study investigates the underlying mechanisms of tension variations through equipment, process, control, and material dimensions. Analysis reveals that insufficient equipment precision, process parameter deviations, delayed control system response, and material performance fluctuations are primary contributing factors. Based on these findings, the research explores control system response mechanisms and feedback strategies, while identifying existing optimization opportunities. By integrating production data and engineering practices, the paper proposes an optimized control model to enhance dynamic compensation capabilities, upgrades automated systems to improve response speed, and modifies key component performance to strengthen equipment stability. These targeted measures aim to effectively suppress tension fluctuations, reduce strip breakage risks, and provide theoretical support and technical references for achieving efficient and stable operation of continuous rolling mills.
