Continuous Cast Secondary Cooling Zone Optimization and Hybrid Adaptive Dynamic Particle Swarm Optimization

Abstract For casting secondary cooling zone production environment is complex and there are a lot of mist interference, the establishment of a continuous casting water optimization model and proposed an adaptive hybrid particle swarm algorithm to solve the optimization problem casting secondary cooling water. Based on the metallurgical process technology requirements established two cold water volume optimization model and on the basis of the classical PSO algorithm is proposed for solving the problem of the hybrid adaptive PSO algorithm. Due to the existence of partial differential equations casting process constraints, traditional optimization method is easy to fall into local optimal solution, dynamic optimization can not achieve good results. PSO study, based on population diversity, constantly updated adaptive particle swarm algorithm parameters, tabu search methods and traditional PSO algorithm combined to enhance the local search algorithm to find the global optimum capacity and global capabilities. The algorithm is applied to dynamic optimization of casting two of cold water, the surface of the experimental results that the algorithm can quickly and efficiently solve the optimization problem. This method is used to optimize casting two cold water is feasible and effective.
