兼顾板形的单机架UCM冷轧机负荷分配的优化方法

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板厚质量,需要在负荷中考虑板形调节能力。综合考虑了单机架轧制各道次轧制压力和板形调节能力,建立了基于粒子群算法的单机架冷轧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,达到了良好的应用效果。

Optimization of Load Distribution in the Single-stand UCM Cold Rolling Mill

As load distribution is the basis of gauge control and shape control,shape adjustment ability should be considered in load distribution to ensure the gauge and shape quality of finished strips.The characteristics of rolling force and shape adjustment ability at each pass of the single-stand mill were comprehensively considered,mathematical model based on PSO for load distribution optimization of single-stand cold rolled strip steel was established and multi-target load distribution optimization for single-s...
