摘要：
The steelmaking-continuous casting process is a complex process. The molten steel needs to select the ladle as a storage device that meets the technological requirements and carry out according to the production plan. When the ladle is matched, the properties of the ladle are numerous, and it is difficult for the matching targets to meet each other at the same time. The steel with many properties lead that the ladle selection constraints are complicate. The optimization of the matching is a multi-conflict target optimization problem. First of all, using the first order inductive learner method to extract the key attributes as the performance indicators, including the highest temperature of the ladle, the highest number of ladle used, the lowest grade of the ladle and the number of ladle outlet, the ladle temperature, the number of ladle, ladle material, the number of skateboarding and frames to be constraints, and establish the ladle matching model. Then, the least general generalization method is used to extract the rules of ladle selection, and the simulation experiments are carried out for many scheduling order strategies and matching priority combinations. Finally, a heuristic ladle matching method based on rule priority was given, and carried out industrial applications. The results show that the accuracy of ladle selection is improved, the number of using ladle and the number of maintenance ladle are reduced. The production efficiency of heat is improved. © 2019, Editorial Board of Journal of Systems Engineering Society of China. All right reserved.
