【摘要】 通过消化剖析某1420冷连轧机组原有的穿带启动轧制过程的数学模型和控制系统,并建立针对此机组的穿带启动轧制过程的仿真平台,分别从工艺和控制角度深入研究了此机组启动轧制过程中存在的问题——张力不稳、启动困难,指出了问题产生的主要原因,提出通过优化启动工艺和控制策略及数学模型解决此机组启动轧制过程中存在问题的技术措施。更多还原

【Abstract】 After digesting and analyzing the mathematical model and control system of strip threading-in process in 1420 cold tandem mill, the simulation of strip threading-in process for this mill has been set up. And based on the simulation system, the problems which are unstable tension and difficult starting-up process that exist in the threading-in process were researched. This paper presents the technical methods to solve the problems of tension in strip threading-in process by optimizing threading-in technics, control system and mathematical model.更多还原
