Abstract A reasonable rolling schedule is a strong guarantee for the quality of aluminum strip and the low power consumption of mill. This procedure set put forward multi-objective function to prevent skidding and balanced four mill power, establish a rolling force model based on Support Vector Regression to replace the traditional mathematical model and improve the accuracy of the prediction of the rolling force effectively. At the same time, it uses Gravitational Search Algorithm to optimize the rolling schedule. The algorithm can not only be able to prevent falling into local extremum point, but also avoid a blind search. So it improved the speed of evolution greatly.This procedure used in the finishing part of“1+4”aluminum hot strip in Henan province, the rolling procedure effect is ideal and it has a guiding significance for the secondary setting calculation.
