摘　　要：分析了中厚板轧制过程的工艺特点,针对某中厚板热轧生产线现状,推导出了板坯尺寸偏差、宽度精度以及ZPC之间的计算模型;采用纵横纵轧制策略时,基于该计算模型结合推床对中实测板坯宽度,通过修改ZPC数值可实现即时补偿由于板坯尺寸偏差引起的钢板宽度偏差,应用效果较好。Based on the technological characteristics of plate rolling process and present situation of a specified plate hot roiling line, the calculation model of slab dimension deviation, the plate width and the ZPC was calculated. On the longitudinal-cross- lon- gitudinal rolling mode, this calculation model was applied, as well as the centering measurement by pushing manipulator and im- mediate compensation of finishing plate width by the ZPC value modification. The control effect was good.
