Embodiment Construction
[0060] In the specific implementation process, the quality of the raw material is the same as that of the steel product, and there is a certain degree of fluctuation in quality. This situation brings difficulties to the control and analysis of the dimensional accuracy of the product in the cold rolling process, so it is necessary to regard this raw material quality fluctuation as an existence The error is integrated into the control and improvement of the dimensional accuracy of cold-rolled finished products. The process equipment of pickling cold rolling and continuous annealing unit is extremely complex, and every production link will affect the dimensional accuracy of the product, and the production process and quality control of various varieties are still being optimized and adjusted. Dynamic management, so the impact trend of process factors and related dynamic changes on thickness and width accuracy.
