| Abstract: | The article introduces the practice process of uncoiler electrical control system of 1700 mm cold rolling mill in Northeast Light Alloy Co., Ltd., which is transformed from power supply by generator set and amplidyne control into power supply by silicon controlled rectifier converter device and simulating control, emphasizes on the different working conditions of direct current motor and silicon controlled recti- fier converter device during whole uncoiler operation,expounds the modified simulating control system and constant tension control principle, as well as winding diameter detection. Finally, it makes analysis on automatic adjustment course of the control system. |
