摘　　要：针对薄规格DP590带钢冷轧过程中焊缝前后区域边裂断带、4#机架轧制力异常增大等问题,对轧机过焊缝模式、切月牙模式、轧制策略、附加张力等进行了优化,实现了0.7mm厚DP590带钢的稳定生产。Aimed at the problem of strip edge crack at the welding zone and the abnormal rolling force increase of No.4 rolling stand when thin gauge DP590 strip was rolled,the processes were optimized including the rolling mode of going through the welding line,the mode of cutting crescent,the rolling strategy and additional tension control.In this way,the 0.7 mm thickness DP590 strip was stably produced.
