Abstract

AGC system for tandem cold mill is an important technology in metal strip field.In accordance with international methods of advanced AGC control,the control schemes about AGC applications of Mitsubishi-Hitachi Metals Machinery and Siemens are compared.Especially about mass flow AGC control,the different control thinkings to improve AGC precision are analyzed.With the rolling product results,the optimize control scheme of different methods of AGC based on hardware condition are explained,and the related control scheme is finally presented for high precision strip gauge control in cold rolling tandem mill.
