高效的利用连铸生产设备的能力是炼钢—连铸生产计划优化技术的主要目标。在描述了炼钢—连铸生产计划调度编制步骤的基础上,重点分析连铸计划编制中问题。针对未充分利用虚拟板坯区间宽度属性及炉次区间宽度因素,并同时考虑浇次中炉次间钢级限制、连浇规程、中间包使用寿命限制、浇铸宽度跳跃限制的条件,建立了连铸计划优化数学模型。根据模型的特点,以蚁群优化算法为基础,设计了双层蚁群优化求解算法,并采用实际生产数据对模型及算法的有效性进行了验证。
The efficient use of continuous casting production equipment is the main goal of steelmaking - continuous casting production planning optimization techniques. On the basis of describing the preparation steps of steelmaking and continuous casting production planning and scheduling, the paper focuses on the problems in the preparation of continuous casting plans. In view of the under-utilization of the width of the virtual slab and the width of the furnace section, taking into consideration the conditions of steel grades, continuous casting process, the service life of the tundish and the limit of the casting width, Casting plan to optimize the mathematical model. According to the characteristics of the model, based on the ant colony optimization algorithm, a two-tier ant colony optimization algorithm is designed, and the actual production data is used to verify the validity of the model and the algorithm.
