Study on AGC Control System of 300 Reversible Cold Strip Mill

In allusion to 300 Reversible cold mill, the composing and the theory of the auto gauge control system is presented. To meet the characteristic of the 300 reversible cold mill, the PID algorithm With Variable Integral Action is used in position and pressure inner loop control of press down hydraulic cylinder to elevate the response characteristic, and the dynamic press compensating algorithm is used in the gauge control outer loop to elevate the precision of strip thickness, and the stability of rolling process.
