Abstract Scope |
Reasonable connection between continuous casting and hot rolling can effectively improve steel production efficiency and reduce energy consumption. In this paper, a hot rolling unit planning method based on casting and rolling interface coordination is proposed to solve the problem that the hot charge rate is difficult to increase due to the lack of casting and rolling interface coordination. In order to improve the hot charging rate and plan quality of hot rolling units, hot rolling slab is preferred. An integer programming model aiming at minimizing billet size penalty, logistics time and maximum rolling weight was established. A multi-objective genetic algorithm combining adaptive optimization and adjustment strategies was designed to solve the problem. The model is tested and validated by using industrial performance data. The results show that compared with the whole method, the proposed model improves the planning quality, size and residence time of hot rolling units by 5.23%. |
