摘　　要： 为充分利用棒线材粗轧机组的能力,应用负荷裕量优化分配的思想计算轧制规程。针对棒线材粗轧机组平辊和立辊交替轧制的特点,在轧件高度和宽度2个方向上使用交替迭代的方法进行计算,迭代过程采用二分法,避免了迭代不收敛问题。结合实际生产数据进行计算分析,结果表明,经该算法优化后,粗轧机组各机架的负荷裕量基本处于同一水平,偏差在3%以内,这种状态能够更加合理地发挥设备能力。 In order to make full use of bar and wire rough mills,the ideology of load margin was applied to optimize to calculate rolling schedule. For the feature of bar and wire rough rolling,that flat roller and vertical roller could roll alter-nately,the iterative calculations were done alternately along the height and width of work piece. And the dichotomy was used during the iterative calculations in order to avoid iteration non-convergence. Combining the rolling schedule with the actual production data,it shows that：the load margins of each stand are at same level after optimization,and the devi-ation is less than 3%,which can be more reasonable to develop the equipment ability.
