摘要：
PURPOSE: A pickling method of Ti(Titanium) cold rolled steel sheets is provided to reduce pickling reaction time by effectively removing oxide scales of Ti and to perform pickling without a salt bathtub and a sulfate bathtub. CONSTITUTION: A pickling method of Ti cold rolled steel sheets is as follows. Ti cold rolled steel sheets are annealed and heat-treated at 700-750°C. The Ti cold rolled steel sheets contact with brush rolls(7) and are mechanically pretreated. The Ti cold rolled steel sheets are pickled in a mixed acid bath(8) by a pickling solution. The mixed acid bath includes nitric acid and hydrofluoric acid. After the pickling reaction is accelerated while contacting the pickled Ti cold rolled steel sheets with brush rolls(9), the Ti cold rolled steel sheets are additionally pickled. The additionally pickled Ti cold rolled steel sheets are washed and rinsed.
摘要（中）：
目的：提供Ti（钛）冷轧钢板的酸洗方法，通过有效去除Ti的氧化皮，并且不用盐浴缸和硫酸盐浴缸进行酸洗，以减少酸洗反应时间。 构成：Ti冷轧钢板的酸洗方法如下。 Ti冷轧钢板在700-750℃进行退火和热处理。 Ti冷轧钢板与刷辊（7）接触，进行机械预处理。 通过酸洗液将Ti冷轧钢板浸渍在混合酸浴（8）中。 混合酸浴包括硝酸和氢氟酸。 酸洗反应加速后，酸洗Ti冷轧钢板与刷辊（9）接触，Ti冷轧钢板进一步酸洗。 另外酸洗的Ti冷轧钢板被冲洗并漂洗。
