摘    要：板形控制为实施自由规程轧制的主要难点。兼顾板形控制的热轧负荷分配优化现已有诸多研究,但其目标函数设计存在着假设条件多、实用性差的缺点。在综合考虑自由规程轧制特殊工艺和板形设定计算众多影响因素的基础上,建立了兼顾自由规程轧制的热轧负荷分配优化模型,并采用模拟退火遗传算法对模型进行了优化计算。在济南钢铁集团公司1 700 mm热连轧机的应用表明,优化后的负荷分配使得自由规程轧制中的板形质量得到提高。

Abstract: One of major difficulties in implementing the Schedule Free Rolling(SFR) lies in the profile and flatness control.There have been quite a few works reported,in which the profile and flatness control is taking into account,addressing on optimal load distribution of hot strip mills.However,assumptions on the design of the objective functions in these works degrade their practicability.In this paper,based on comprehensive considerations of influential factors including special technology in SFR and the shape setup,a model for optimal load distribution in SFR of hot strip mills is established,and simulated annealing genetic algorithm is applied for the optimization process.The practical test on the optimization scheme with Jinan Iron and Steel Company 1700mm hot strip mill shows that the optimal load distribution brings in improved shape quality in SFR.
