[0060] In the specific implementation process, the quality of the raw material is the same as that of the steel product, and the quality fluctuates to a certain extent. This situation brings difficulties to the dimensional accuracy control and analysis of the cold-rolled product. Therefore, it is necessary to take this raw material quality fluctuation as an existence. The error is integrated into the control and improvement of the dimensional accuracy of the cold-rolled finished product. The process equipment of pickling cold rolling and continuous annealing unit is extremely complex, and no production link will affect the dimensional accuracy of the product, and the production process and quality control of various varieties are still being continuously optimized and adjusted, and the process system of the product is always at the Dynamic management, so the influence trend of process factors and related dynamic changes on thickness and width accuracy.
