摘　　要：随着包钢稀土钢板材公司2250 mm热轧生产任务量的加大,轧制节奏对产量的提高有非常重要的影响,为此着重分析了影响轧制节奏的原因。通过对2250 mm热轧生产线精轧区域制约轧制节奏的因素进行梳理优化,轧制节奏提高,轧制间隙时间缩短,平均小时产量提高了2.3块,使2250 mm热轧生产线的产能突破了年产550万t设计目标。With the increase of task load for 2250 mm hot rolling production line in Inner Mongolia Baotou Steel Rare Earth Steel Plate Co.,Ltd.,the effect of rolling rhythm on production increase is very important so that the causes influencing rolling rhythm are emphatically analyzed.The rolling rhythm is improved,gap time of rolling is shortened and average hourly output increases by 2.3 pieces through unscrambling and optimizing the factors restricting rolling rhythm in finishing area of 2250 mm hot rolling production line so that its capacity exceeds the design target of 5.5 million tons per year.
