Abstract: Some embodiments of the disclosure provide a method for homogeneously controlling a transverse temperature during laminar cooling of a hot-rolled strip. In an embodiment, a mathematical model of middle convexity cooling in a water volume is established by designing different types of middle convexity water cooling heat transfer coefficient curves. Process procedures and equipment parameters of the hot-rolled strip during the laminar cooling are considered to restore the actual situation on site. Through finite element calculation, an optimal middle convexity water cooling heat transfer coefficient curve is obtained. Process parameters corresponding to middle convexity water volume distribution during the laminar cooling (a water flow density) are further obtained to guide a water volume control process.

Abstract: A second type computer assembly line balancing optimization method based on a migration genetic algorithm, and related to the technical field of assembly line balancing. The method uses assembly experience of similar assembly lines, the feasible solution set of the known assembly lines is transferred to the initial solution set of the assembly line balancing problem to be optimized, due to the migration of high-quality feasible solutions. The method can effectively reduce the sensitivity of the algorithm performance to the initial value and parameters, and improve the lower limit of the local optimal feasible solution of the heuristic algorithm to solve the assembly line balancing problem.
