Abstract
PURPOSE: To obtain a pickled plate with uniform and beautiful appearance by using a pickling liquid containing a specific amount of Cu ion.
CONSTITUTION: For example, in a pickling liquid of a continuous pickling line equipped with plural hydrochloric acid pickling tanks, 20W50ppm of Cu ion is contained. Cu ion is provided by supplying a CuCl2 powder in the pickling liquid. In a pickled plate pickled by the resultant pickling liquid, a streak like pattern is not generated on a surface thereof and uniform and beautiful appearance is obtained.
