【Abstract】 Digital simulation has been carried out for the plate thickness control system of the modern tandem cold rolling mills installed in Wuhan Iron and Steel Company (WISCO). The control system is a complicated one with many inputs and outputs. Based on an analysis of the thickness, speed, the hydraulic roll gap and the strip tension control system, a simulation model has been developed in accordance with the transfer function of the control system and the technological model. The program is written in FORTRAN language. Many subroutine programs are provided in order to facilitate any alteration or revision and transplantation. The simulation results are checked with the directly measured curves so as to improve the simulating accuracy. The error of simulation as checked with the data measured is smaller than 30%. Suggestions for further improvement of the thickness control system are made.更多还原
