基于TDC的1500热连轧卷取机助卷辊自动踏步控制系统

TDC-based wrapping roll automatic jump control system for a 1500mm hot strip mill coiler

摘要: 莱钢1500mm热连轧是一套国内自主设计生产的全自动化热连轧机组,卷取机助卷辊自动踏步控制(automatic jump control,AJC)功能对于产品的最终质量及相关设备具有重要影响.该套AJC系统是国内自主开发的基于SIEMENS TDC系统的宽带钢热连轧机AJC系统.在西门子STEP开发平台完成所有的软件编程,并利用西门子WinCC设计了界面友好的人机接口系统,实现了系统的全自动控制.系统功能完善,控制精度高,在莱钢1500mm热连轧卷取机上得到了应用,并取得了良好的效果.

Abstract: The Laigang 1 500 mm hot strip mill is a set of fully automatic hot strip mill designed and manufactured by us. The automatic jump control (AJC) of wrapping rolls is very important for the final quality of products. The system is the first set of AJC system based on Siemens TDC and designed by us. The system functions were programmed in Siemens STEP7 and friendly HMI was designed with Siemens WinCC. The system, with comprehensive functions and high precision, was applied on the Laigang 1 500 mm hot strip mill and satisfactory results were obtained.
