3.Continous pickling line,characteristic is higer efficiency,high output and low electric consumption etc, the line can produce 600 000- 1200 000 tons/year. Following is  the data for continuous pickling hot rolled strip with the annual yield of 800 000 tons.

 4. Process Flow of the pickling line:

Manually loading→entry coil car →No.1 pay -off reel →No.1 pay -off reel scraper →No.2 pay -off reel →No.2 pay -off reel scaper →No.1 five -roll leveler → No.2 five -roll leveler →deflector roll →double shears →joint pinch roll →welder →No.1 bridle roll →No.1 horizontal looper →No.1 CPC →NO.2 bridle roll →descaler →No.3 bridle roll →pickling tank →risning tank →blowing machine →hot air drying  →No.3 bridle roll  →No.2 double roll CPC →No.5 bridle roll →pinch CPC unit →disc shear →scrap coiling →three -roll tension roller →No.3 exit shear →electrostatic oiling →exit deflecting  →pressing roll →coiler →exit coil car →loading platform.
