Embodiment Construction
[0069] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.
[0070] Taking the actual data measured by the shape meter in the production of a cold-rolled coil factory in China as an example, when producing strip steel of a certain specification, the shape meter opened 22 effective channels in total, and detected 327 sets of data in total, with a total of 7194 shapes Record the value, and make a comprehensive fuzzy score judgment on all the shape residual data as follows:
[0071] Take the 100th detection data as an example, such as figure 2 shown. The shape residual data are shown in Table 1 below:
