用連續酸洗機組去除熱軋帶卷的表面氧化鐵鱗。酸液過去用硫酸﹐現在多用鹽酸。

酸洗前先行焊接併捲﹐有的還經連續“黑退火”。酸洗後進行清洗、烘乾和剪邊、分卷。

The production processes of pickled cold-rolled coils include laser (beam) welding, stretch flattening,
sulfuric acid pickling, skin pass, side cut, oiling, etc. Pickled cold-rolled coil heads and
tails can be used to produce low-, mid-, and high-strength steel for stamping,
automobile structural steel, etc, and they are mainly delivered in the shape of coils.
