The Mill Pacing Research Based on the Optimized Plate Model

Abstract:

In This paper, in the background of a plate milling system in China, various influences on mill pacing in plate rolling are taken into consideration, a plate model by using the objective optimization theory based on the field statistics are introduced. This model based on the differential evolution, that establishes the objective function of rolling quality-temperature waiting time-rolling time, and uses concurrent optimization for the plate rolling of various needs. The results could get a series of Pareto sets to content the different requirements of determining the contiguous slab’s out-stove time interval. Lastly, the test examples are simulated to check up, the Pareto sets are calculated, and the result shows the method is effectiveness.
