研究了AOD全铁水冶炼和电炉钢水冶炼两种不锈钢冶炼流程,结果表明,AOD全铁水冶炼不锈钢可以弥补电炉钢水冶炼流程中电炉产能小于连铸产能的缺陷。提出了一种结合AOD全铁水冶炼和电炉钢水冶炼的混合流程。提出了各个工序间钢包最长传搁时间最短为调度目标是更加合理的调度方式,应用遗传算法求解混合流程最长钢包传搁时间最小为60min,小于单纯以连铸机为中心的组织生产调度,既保证了钢包正常的运输,又有足够的时间进行必要的调度和调整。最后,给出混合流程最优调度的甘特图,并基于最优调度并采用统计分析的方法得出工序间传搁过程温降的经验公式,由此给出混合流程最优调度的温度制度。
The results show that the AOD all-metal smelting stainless steel can make up the defects that the EAF capacity is smaller than the continuous casting capacity in the EAF process. A hybrid process combining AOD all-metal smelting and EAF molten steel smelting was proposed. It is proposed that the shortest larboard transfer time among all processes is the most reasonable dispatching schedule for the dispatching target. The minimum ladle transfer time of the ladle with genetic algorithm is less than 60min, which is smaller than that of the simple caster , Not only ensure the ladle normal transport, have enough time to make the necessary scheduling and adjustment. Finally, the Gantt chart of the optimal scheduling of the hybrid process is given. Based on the optimal scheduling and the statistical analysis method, the empirical formula of the temperature drop during the transfer process is obtained, and the optimal scheduling temperature of the hybrid process is given .
