ABSTRACT:
A jet pickling apparatus for pickling the surfaces of continuously moving sheet material (12) has tips of the nozzle headers (41-43) for discharging a pickling fluid (19) on the surfaces of the sheet and into a pickling tank (31) formed into a slit shape (41a-43a), and the nozzles (41,42) at the entrance side are installed to eject pickling fluid in the same direction as the running direction of sheet while the nozzle (43) at the exit side ejects the pickling fluid in the direction opposite to the running direction of the sheet. Therefore, there is no gas in the pickling tank (31) and the tank is filled with the pickling fluid (19), which eliminates the problems of floating of the sheet (12) and insufficient contact of the pickling fluid (19) with the sheet surfaces, allowing thorough pickling and improving the pickling effect.
