This application provides a method and storage medium for improving the thickness qualification rate of cold-rolled strip steel products, relating to the field of steel rolling production technology. The method includes: after starting the rolling mill, increasing the initial rolling speed for this rolling operation; during the rolling process, when the thickness deviation of the strip steel is within the allowable deviation range, increasing the rolling speed in a first stage; when the rolling speed after the first stage of speed increase exceeds a first limit value, switching the control mode in the automatic thickness control system from feedback AGC to per-second flow control, and simultaneously increasing the rolling speed in a second stage; when the rolling speed after the second stage of speed increase exceeds a second limit value, increasing the rolling speed in a third stage, where the second limit value is greater than the first limit value; and automatically tailing the strip steel at the highest process rolling speed during the tailing stage. This method can reduce the number of meters of thickness deviation at the head and tail of the strip steel, reduce longitudinal thickness deviation, and lower production costs.

This invention provides a roll gap adjustment method applicable to the cold continuous rolling process of ultra-high strength steel, comprising the following steps: First, establishing a thickness deviation prediction model for ultra-high strength steel, and predicting the thickness deviation rate γ for the nth and (n+1th)th thicknesses of the i-th coil of incoming strip. i,n γ i,n+1 Calculations are performed; secondly, a roll gap adjustment prediction model is established to calculate the mill roll gap adjustment ΔS. i An objective function for the optimal roll gap adjustment during the rolling process is established. Based on an optimization method, the objective function for the optimal roll gap adjustment is solved to obtain the optimal roll gap adjustment. This method can overcome the full-length thickness variation and head-to-tail thickness deviation issues that occur in the traditional automatic thickness control system of cold rolling mills during the rolling of ultra-high strength steel, greatly improving the thickness control accuracy of ultra-high strength steel.
