【摘要】：在冷装工艺生产模式下,不合理的轧制计划将导致不必要的钢坯库倒垛作业,严重时甚至会造成轧制生产的延迟或中断.本文在已知轧制计划和实时钢坯库存堆放情况的前提下,对轧制计划设置了三种调整策略:轧制钢坯替换、轧制单元内钢坯轧制顺序调整以及计划钢坯取消轧制调整.基于调整策略,建立了以最小化调整惩罚及实施计划时的钢坯库倒垛次数的加权平均和为目标的数学模型,并结合问题特征设计了三阶段求解算法(THA).通过基于实际生产数据的实验验证,结果相对于原轧制计划,在满足轧制工艺规程前提下大量减少了钢坯库的倒垛次数,算法和模型是可行且有效的.
[Abstract]:In the cold loading process production mode, unreasonable rolling plan will lead to unnecessary billet storehouse stacking operation, In this paper, under the condition of known rolling plan and stock stacking of real-time billet, three adjustment strategies are set up for rolling plan: rolling billet replacement, rolling billet replacement, rolling billet replacement, rolling billet replacement, rolling billet replacement, rolling billet replacement, rolling billet replacement, rolling billet replacement, rolling billet replacement, Based on the adjustment strategy, a mathematical model with the objective of minimizing the adjustment penalty and the weighted average sum of the stacking times of the billet depot in the course of carrying out the plan is established, and the rolling order adjustment of the billet in the rolling unit and the cancellation of the rolling adjustment of the planned billet are carried out. According to the characteristics of the problem, a three-stage solution algorithm is designed. The experimental results based on the actual production data show that compared with the original rolling plan, the number of stacking of the billet depot is greatly reduced under the premise of satisfying the rolling process schedule. The algorithm and model are feasible and effective.
