为解决炼钢-连铸与热轧生产调度方案之间协同联动、保障连续生产的问题,提出以炼钢-连铸为动态调度主体、以热轧为辅助协调的动态协调策略,将炼钢与热轧调度的动态协调问题分解为两个子问题,以最大化每一炉次浇铸完工时间的一致性、最小化板坯连轧惩罚值以及最小化板坯轧制时间差异为优化目标,建立炼钢-连铸动态调度模型及热轧动态协调模型。通过炼钢-连铸动态调度算法最小化出坯时间差异,再通过热轧动态协调方法对不同送坯工艺要求的板坯进行轧制方案调整。仿真实验表明本文提出的模型和算法是可行的和有效的。
In order to solve the problem of coordinated production between steelmaking-continuous casting and hot-rolling production schedule and ensuring continuous production, a dynamic coordination strategy based on steel-making-continuous casting as dynamic scheduling and hot rolling as auxiliary coordination was proposed. Steelmaking The dynamic coordination problem with hot-rolling schedule is decomposed into two sub-problems, which are optimized by maximizing the consistency of the completion time of each furnace, minimizing the penalty value of slab continuous rolling and minimizing the difference of slab rolling time Steelmaking - Continuous Casting Dynamic Scheduling Model and Hot Rolling Dynamic Coordination Model. The steelmaking-continuous casting dynamic scheduling algorithm is used to minimize the difference of billeting time, and then the rolling schedule is adjusted by the dynamic coordination method of hot rolling. Simulation experiments show that the proposed model and algorithm are feasible and effective.
