摘　　要：冷、热连轧的发展首先在冷连轧机上实施了张力信号与辊缝闭环的恒张力和恒厚度控制方法。分析出张力与辊缝闭环的厚控系统存在极限精度,所以要求提高坯料厚度精度、第一机架用偏心最小的轧辊和DAGC。将张力(或活套电流)与辊缝闭环的流量AGC应用到热连轧机上可以大大提高热连轧板带厚度精度,估计可达到±15μ。Cold,hot continuous rolling firstly implement the constant-tesion control and constant-guage control of the tension-signal and roller slot closed loop in cold continuous rolling machine.This thesis analyze limite precision between tension and roller loosed loop guage control system,so this require to improve material thickness precision,use roller of minimum eccentricity in first machine and DAGC.Using tension(looper electricity) and flux-AGC of roller guage closed loop in hot continuous rolling machine can improve hot continuous rolling guage precision greatly,it is estimated that the precision can be ±15μ.
