摘要
Owing to the frequent variation in steel grades,plate dimensions,mill pacing,and mill working conditions,the zero point of a plate mill fluctuates accordingly,potentially leading to incorrect plate thickness results.Using the actual measured thickness curve data,a zero-point correction model was developed based on lot classifications with respect to the steel grade,dimensions,and last-pass rolling force.The application of this model achieves enhanced variation prediction of the zero point and improved plate-thickness control.
