1200mm四辊可逆式冷轧机AGC系统性能分析

Properties Analysis of AGC System of the 1200mm 4Rollers Reversible Cold Mill

结合国营九零二厂１２００ｍｍ四辊可逆式冷轧机的改造工作，立足于对引进设备进行消化、吸收，对该轧机的厚度自动控制系统进行了全面的理论分析、实测，掌握了其性能，从中找出了该套系统所存在的问题，为该机的调试和改造提供了理论依据和前提．

This paper is based on the reforming work of the 1200 mm 4 rollers reversible cold millin the state operated 902 factory. It is a aimed at digesting and absorbing the importfacilities. The automatic gauge control system (AGC)of thiscold mill has been theoretically analysed completely and measured on the spot. Now its properties have been graspedcompletely, and from this,the defects existing in this system have been found out.It provides the theoretical basis and prereguisite for the reforming work of this cold mill.
