摘　　要：某中厚板厂精轧机在调试后出现厚度自动控制不稳定的问题,主要表现在设定厚度与实际厚度差别较大、同板厚度差较大等。针对精轧机厚度控制不稳定的问题,通过优化L1控制程序的咬钢冲击补偿系数、EGC漂移补偿系数以及主平衡压力波动等,达到了精轧机高精度厚度自动控制和提高成材率的目的。The automatic gauge control system worked unstably after the commissioning of finishing mill of Certain Heavy and Medium Plate Mill, with main problems of big difference between preset and actual gauges and big intra-plate gauge deviation. In order to address the problems, Level 1 control program was optimized on biting steel impact compensation coefficient, EGC drift compensation coefficient and main balance pressure fluctuation. As a result, the goal of achieving precisely automatic gauge control at finishing mill and increasing rolling yield was accomplished.
