Embodiment Construction
[0020] Taking 50W310 high-grade silicon steel as an example, the sample thickness is 0.5240mm. In order to ensure the thickness accuracy of the finished product, manual and accurate calibration is performed according to the 0.5240mm sample. The middle pass thicknesses are 2.6mm, 1.8mm, 1.0mm, and 0.6mm respectively.
[0021] 1. Manually measure the silicon steel sample with a thickness of 0.5240mm 5 times on the operation interface of the γ-ray thickness gauge, and obtain the measured thickness values of 5 samples, and then divide the sum of the measured thickness values of the 5 samples into 5 = the average measured thickness value ;
[0022] 2. Compare the average measured thickness value of silicon steel with the absolute thickness value of the 0.5240mm sample to obtain the deviation value of the sample thickness (that is, the deviation value of the sample thickness = the average measured thickness value - the absolute thickness value of the sample); the absolute thickn...
