厚度精度是衡量板带材产品质量的主要指标之一，加减速过程是可逆轧机厚度控制的关键环节。为了研究双机架可逆冷连轧机组加减速过程中的轧制特性，以制定相应的补偿策略，利用动态连轧理论开发了机组的动态特性仿真程序，分析了加速过程中带材厚度和张力的变化规律，建立了加速过程中同时考虑摩擦系数和油膜厚度的全辊缝补偿模型。研究结果表明：采用所建立的补偿策略后，加速过程中的厚度精度已满足生产要求，张力减小量也大大降低。研究结果可为该类轧机加减速过程的控制提供有益参考。

Thickness is one of the main quality indexes of strip production. The acceleration and deceleration proces-ses are the key links of thickness control in the reversible rolling mill. In order to research the characteristics in this stage and present a proper compensation strategy,the dynamic characteristic analysis model of two-stand reversible <br> continuous cold rolling mill was established by using dynamic continuous rolling theory. The strip thickness and tension variation process of a four-pass rolling schedule in the acceleration process were obtained with and without compensation. A new thickness compensation model for acceleration process was deduced by considering both fric-tion coefficient and oil-film thickness of oil-film bearing. The results show the thickness precision meets the produc-tion requirement well and the tension decrease amount reduces dramatically after taking the compensation strategy by considering both friction coefficient and oil film. The results are beneficial for thickness control in the accelera-tion and deceleration process of such mill.
