specific Embodiment approach 1
[0016] The method for controlling the difference between the steel plate head and the same plate is characterized in that it comprises the following steps:
[0017] 1) Detect the thickness of the steel plate,
[0018] 2) Multiple data points are set on the head of the steel plate to detect the thickness of the steel plate at the data point in real time;
[0019] 3) Roll the steel plate, and set the thickness of the finished steel plate to be rolled. The steel plate with a finished steel plate thickness less than 14 mm enters step 4), and the steel plate with a finished steel plate thickness greater than 14 mm enters step 5);
[0020] 4) During the rolling process of the steel plate, in each rolling pass, according to the thickness of the steel plate measured in step 2), the roll gap width of the rolling rolls is adjusted to eliminate the high points in the data points, so as to realize the alignment of the steel plate head Part of the rolling compensation, to obtain the same ...
