Pickling method of metal plate |
摘要 |
A pickling method which can effectively conduct pickling, and can shorten pickling time. The strip is plastic elongated by 0.1 to 10% before it is introduced into the pickling tank to form cracks. The strip is bent so that a surface strain of the strip is 0.2 to 1 times the plastic elongation during dipping the strip in the acid solution of the pickling tank, thereby making the cracks open and close, and supply of a fresh acid solution and expelling of an exhausted acid solution may be effectively conducted. Scale always contacts with a fresh acid solution by this bending operation, so that a scale dissolution reaction proceeds fast, thereby being capable of shortening the pickling time.
