Automatic Control System of Direct Tension-type Pilot Cold Rolling Mill

To meet iron and steel enterprises requires to strengthen research capacity in cold-rolled production technology,State Key Laboratory of Rolling and Automation(RAL) independently designed and developed a new direct tension-type pilot cold rolling mill,which includes a vertical hydraulic automatic gauge control(HAGC) generating tension through the hydraulic cylinders and chucks on both sides of the horizontal direction to realize automatic tension control(ATC).The equipment constitute,main functions and features of direct tension-type pilot cold rolling mill were introduced briefly.The control system structure and the realization of automatic control functions were illustrated.The control precisions were gotten through system testing.The testing results showed that the experimental process may simulate the cold rolling production process to develop steel grade and research technology.
