摘　　要：负荷分配是板厚控制和板形控制的基础,为了保证成品带钢的板形和板厚质量,需要在负荷分配中考虑板形调节能力。本方法综合考虑了单机架轧制各道次轧制压力特性和板形调节能力,建立了基于粒子群算法的单机架冷轧硅钢负荷分配优化数学模型,并利用该算法实现了单机架冷轧机多目标负荷分配优化。采用优化后的轧制规范组织实际生产应用,结果表明该优化模型很好地兼顾了板形控制和板厚控制,取得了良好的应用效果。As load distribution is the basis of gauge and shape control, shape adjustment ability should be considered in load distribution to ensure the shape and gauge quality of final strip. Mathematic model based on PSO algorithm for optimizing load distribution in single-stand silicon steel rolling was established taking into account the characteristics of rolling force at each pass and shape control ability. Multi-target load distribution optimization was realized using this model. Application of this method in production resulted in better shape and gauge control.
