【摘要】：随着我国装备制造业务的飞速发展,各种新式的铝加工设备层出不穷,特别是轧机设备在类型、规格上不断扩充完善。比如铝带冷轧机就有从800mm到2300mm、从四辊到六辊的多种不同规格的产品。不同规格的设备,尽管功能相同,但是实际的设计总是不同的,从而对控制程序的要求也不一样。为了满足这些多样化的要求,通过总结以往控制程序的经验,并借鉴国外先进控制程序的优点,开发了高速冷轧机标准机列控制系统。高速冷轧机机列控制系统是一个复杂而庞大的大型控制系统,主要由传动控制系统、厚度板型控制系统和机列控制系统组成。本控制系统主要应用于四辊或六辊铝带冷轧机的机列系统的控制,论文首先介绍了国内外高速冷轧机控制系统的现状及先进控制系统的特点,并分析了冷轧机机列控制系统的具体需求。论文详细阐述了冷轧机机列控制系统总体设计思路和设计方法。控制程序采用了模块化的设计方法,所有子系统独立设计,提高了系统稳定性,缩短了开发周期。控制程序还借鉴了面向对象的程序设计思想,整个程序在底层对象的基础上开发,提高了代码复用水平。这种设计思路不仅简化了调试人员的工作,缩短了调试周期,而且提高了自动控制水平,简化了用户操作。为了实现面向对象的设计思想,在单体设计中,首先对功能相似或相同的对象进行分类,然后把这些对象变成基本的底层功能块,通过对这些对象功能块的组合和连接,组装出各个功能单体的程序。论文重点介绍了辅助泵站、皮带助卷器、卸卷小车等主要单体的详细设计过程和主要程序代码。人机界面采用功能强大的WinCC监控软件编写,WinCC集成在Step7中,可以实现控制软件中变量、报警信息等直接转化为WinCC监控系统中的变量,使得组态工作效率大大提高。监控画面中不仅包含液压泵站操作、工艺润滑的监控、设备动作和自动流程的监控,而且具有故障报警、趋势绘制、报表打印等功能,实现了对整个轧机系统的全面监控和可靠控制。
[Abstract]:With the rapid development of equipment manufacturing in our country, various kinds of new aluminum processing equipment emerge in endlessly, especially the rolling mill equipment in the type, the specification unceasingly expands and consummates. For example, aluminum strip cold mill from 800mm to 2300mm, from four-high to six-roll products of different specifications. Different specifications of equipment, although the same function, but the actual design is always different, so the control program requirements are different. In order to meet these diversified requirements, the standard train control system of high speed cold rolling mill is developed by summing up the experience of previous control programs and drawing on the advantages of foreign advanced control programs. The high speed cold rolling mill train control system is a complex and large scale control system, which is mainly composed of transmission control system, thickness plate type control system and train control system. This control system is mainly used to control the train system of four or six high aluminum strip cold rolling mill. Firstly, the paper introduces the present situation of the control system of high speed cold rolling mill at home and abroad and the characteristics of the advanced control system. The specific requirements of the cold mill train control system are also analyzed. The overall design idea and design method of cold rolling mill train control system are described in detail in this paper. The control program adopts the modular design method, all subsystems are designed independently, which improves the stability of the system and shortens the development period. The control program also draws lessons from the object-oriented programming idea. The whole program is developed on the basis of the underlying object, and the level of code reuse is improved. This design idea not only simplifies the work of the debugging staff, shortens the debugging period, but also improves the automatic control level and simplifies the user operation. In order to realize the idea of object-oriented design, in monomer design, the objects with similar or identical functions are first classified, and then these objects are transformed into basic underlying functional blocks, which are combined and connected to each other. The process of assembling each functional unit. This paper mainly introduces the detailed design process and main program code of auxiliary pump station, belt winder, unwinding trolley and so on. The man-machine interface uses the powerful WinCC monitoring software to compile and integrate WinCC in Step7, which can realize the control of variables in the software and alarm information directly into the variables in the WinCC monitoring system, so that the configuration efficiency is greatly improved. The monitoring screen includes not only the operation of hydraulic pump station, the monitoring of process lubrication, the monitoring of equipment action and automatic flow, but also the functions of fault alarm, trend drawing, report printing and so on. The overall monitoring and reliable control of the whole rolling mill system is realized.
