摘要:铝热轧机带材生产工艺及设备特性没有标准手册,只有参考文献。本文首先对铝热轧的基本性能、加工原理、技术特点及其优越性进行简析,在此基础上分析弯辊控制原理,探析几种弯辊控制方法对工艺质量的影响,综合分析各种弯辊控制模式的优缺点,提出热轧弯辊控制发展方向。其次,对热轧生产过程中厚度波动的干扰因子进行分析,提出应对这些干扰因子的厚度控制系统理论,探讨减小厚度波动控制理念。最后提出对铝热轧生产工艺及设备特性的发展趋势、改善潜能及改善方向的几点看法。
Abstract: There is no standard manual for the production process and equipment characteristics of aluminum hot rolling mill strip, only reference documents. This article first analyzes the basic performance, processing principle, technical characteristics and advantages of aluminum hot rolling. On this basis, it analyzes the bending roll control principle, explores the influence of several bending roll control methods on the process quality, and comprehensively analyzes various The advantages and disadvantages of the bending roll control mode, the development direction of hot rolling bending roll control is proposed. Secondly, the interference factors of thickness fluctuation in the hot rolling production process are analyzed, the thickness control system theory to deal with these interference factors is proposed, and the control concept of reducing thickness fluctuation is discussed. Finally, some opinions on the development trend, improvement potential and improvement direction of aluminum hot rolling production process and equipment characteristics are put forward.
