摘　　要：通过对冷连轧机厚度控制(AGC)系统中常规方式与扩展方式的比较,剖析了偏心控制在冷连轧机高精度板厚控制中的应用,对不同模式厚度控制方式下的轧机生产实际进行了对比,分析影响产品厚度减薄因素分别为轧机偏心控制、来料厚度波动、轧机张力控制波动、测厚仪、测速仪精度,并提出轧机轧制厚度补偿控制模型改善方案,提高产品厚度精度。The application of eccentricity control for high precision gauge control of tandem cold mill is analyzed through comparing the conventional and extended modes in automatic gauge control(AGC)system of tandem cold mill.Moreover,such influencing factors of thinning for product thickness as eccentricity control of rolling mill,thickness variation of incoming materials,variation of tension control for rolling mill as well as precision of thickness gauge and tachymeter are analyzed by comparing the production situations of rolling mill with different thickness control modes.As a result,the improvement scheme that rolling gauge of rolling mill compensates control model is proposed to improve the thickness precision of products.
