摘　　要：安钢炉卷轧机液压自动厚度控制系统,采用轧机刚度控制、GM-AGC、X射线厚度偏差监控,由油膜、冲击、轧辊热膨胀磨损、轧辊偏心等补偿功能来控制钢板厚度。由于环境恶劣,测厚仪不能正常使用,严重降低了厚度控制精度,同板差较大。通过对影响厚度精度较大的轧机刚度控制和GM-AGC进行优化,提高了钢板同板差的控制精度。Controlled by mill rigidity and monitored by GM-AGC and X-ray gauge deviation, the hydraulic automatic gauge control system of Angang Steckel Mill controls the plate thickness by compensation functions of oil film, impact, roll heat expansion and wear and roll eccentricity. Due to the harsh environment, the gauging device could not work normally and gave very low gauge control precision with big intra-plate gauge deviation. The control precision of this deviation was improved by optimizing mill rigidity control and GM-AGC, which affected the gauge precision heavily.
