Intelligent Optimization of Load Distribution on Hot Rolled Strip Steel Based on Improved Spotted Hyena Algorithm
Aiming at the problem that control effect for shapes of steel plates was not good due to uneven load distribution in terms of the continuous hot rolling process,the objective function with uniform load distribution and good shapes of plates was established based on traditional rolling mechanism,while the spotted hyena algorithm and the improved spotted hyena algorithm were used to optimally find the solutions to the load distribution of both single target and double target.The achieved results showed that by the improved spotted hyena algorithm the relative convexity difference of the last frame reduced from 0.000 834 5 to 0.000 014 83 and-0.000 026 34,and these values were in the allowable range.As for the load distribution of the upstream frames,their distribution was reasonable,which fulfilled completely the rolling capacity of the rolling mill.
