在板带材生产中,产品的厚度精度和平直度是反映产品质量的两项重要指标。由于AGC系统引入轧制过程,使纵向厚度精度得到了显著的提高,完全能满足目前对质量的要求。所以目前研究的重点就在于寻找板带横向厚度(或称截面)和板形(或称平直度)的控制方法。传统的控制方法有初始轧辊凸度和冷却液控制两种方法。初始轧辊凸度法一般用作辊缝设,定利用轧辊的凸、凹度来补偿轧制过程中因弯曲或温度变化等因素引 In strip and strip production, product thickness accuracy and flatness are two important indicators of product quality. As the introduction of AGC system rolling process, the vertical thickness accuracy has been significantly improved, fully able to meet the current quality requirements. Therefore, the current research focuses on finding the control method of horizontal thickness (or cross section) and plate shape (or flatness) of the strip. The traditional control methods are initial roll crown and coolant control two ways. The initial roll crown method is generally used for roller seam set to take advantage of roll convexity and concavity to compensate for the rolling process due to bending or temperature changes and other factors cited
