摘　　要：综合采用"倒车+喷淋+挤干+二次酸洗"的方法,可以有效消除冷轧酸洗停车斑缺陷。基于这一机理,利用酸洗工艺段的前后活套裕量和机组联动,实现定尺倒车功能;在酸洗槽前增设一套喷淋挤干装置,将漂洗槽中带钢倒出时的残留酸液冲洗掉,防止倒车对上游设备的腐蚀。该套方案在现场应用后基本可以消除酸洗停车斑缺陷,提高酸洗工序的成材率。The ＂reverse ＋ spray ＋ squeeze ＋ secondary pickling ＂ method can effectively eliminate the parking cicatrices defects of cold rolling pickling.Based on this mechanism,using the front and rear loopers of the pickling process section and units linkage to realize scale reversing function;adding a spray squeezing device in front of the pickling tank rinses the residual acid off,preventing the corrosion on the upstream equipments.This method used in field can eliminate onsite parking cicatrices defects and improve the yield rate of the pickling process.
