摘    要：冷连轧机辊缝自动标定是液压辊缝控制中精度要求最高的环节之一,2007年鞍钢股份有限公司新建1 450 mm冷轧机采用德国Siemens公司TDC控制系统,实现了辊缝自动标定功能。作者从应用角度分析了轧机辊缝自动标定的分类与过程,阐述了轧机辊缝自动标定时,如何实现相对轧制力、辊缝位置、辊缝倾斜的零点标准,同时,对现场标定过程出现的典型故障进行分析并提出解决方法。实践证明通过辊缝自动标定,可以提高轧机HGC精度,保证成品带钢的厚度要求。

Abstract: Roll gap automatic calibration of tandem cold mill is one of the most complex system with high precision in hydraulic roll gap control system.New 1 450 mm tandem cold mill was built in Angang Steel Co.,Ltd.in 2007.Siemens TDC control system was adopted,and automatic calibration function of roll gap was achieved.Classification and process of roll gap automatic calibration for rolling mill are analyzed from application angle.How to realize zero criterion of relative roll force,relative roll gap and relative tilting are explained.Typical troubles arisen in field calibration process are analyzed,and their solution is presented.It is confirmed that through roll gap automatic calibration,HGC accuracy of rolling mill and thickness accuracy of strip were improved.
