MINI-MPM连轧管机组的二级自动控制功能

Control Functions of 2-level Automation System for MINI-MPM Plant

摘要: 在介绍包钢MINI-MPM连轧管机组的二级自动控制系统的基础上,重点对连轧管机的前馈、反馈,张力减径机的前馈、反馈自适应控制功能和连轧管机的头尾削尖控制、管长控制、自动辊缝控制及张力减径机的管端增厚控制等实时控制功能的原理及其计算方法进行了分析,并给出了轧制的实际验证效果。

Abstract: Introduced in the article is the 2-level automation control system of the Baogang MINI-MPM, focusing on analysis of the principles and calculation methods for the real-time control functions, namely, the self-adaptability control for feed forward/feedback of the MPM proper and feed forward/feedback of the stretch reducing mill, MPM shell-end sharpening control, shell length control and roll gap auto control as well as tube-end upsetting control of the stretch reducing mill. Also described is the result of the verification via actual rolling operation.
