AI Technical Summary
In the cold continuous rolling process of strip, traditional roll speed control methods are difficult to achieve high-precision control at high speeds. Thickness and tension control are strongly coupled, which makes the control process difficult and inaccurate, affecting the stability of the rolling process.
The thickness control adjustment amount is used as the main correction amount for the roll speed, and the tension control adjustment amount is used as the limit value for the roll speed. The rolling process parameters are calculated through the target optimization algorithm, and the roll speed is allocated and corrected according to the speed ratio of adjacent stands and the tension limit value, so as to achieve precise control of the roll speed.
It improves the thickness accuracy of strip products and the stability of the rolling process, realizes high-precision control of roll speed, reduces control difficulty and improves control accuracy.
