Abstract
The utility model discloses a stainless steel plate pickling device, which comprises a pickling bath set. The device is characterized in that the pickling bath set comprises sulfuric acid sections and mixed acid sections; clearing and brushing machines are arranged between the sulfuric acid sections and the mixed acid sections; and a pre-flushing device, the clearing and brushing machines and a countercurrent rinsing device are sequentially arranged in rear of the mixed acid sections. The device has the advantages that the pickling device in the stainless steel plate continuous annealing pickling set is reasonably distributed; ferric oxide on the surface of a band steel is flushed through a pre-spaying device; pre-pickling is performed through a pickling section; water flushing is performed to the band steel through two clearing and brushing machines, so as to remove the ferric oxide on the surface of the band steel; the requirement of speed of the band steel is satisfied through two mixed acid sections; acid and impurities on the surface of the band steel are removed through the pre-flushing device; water flushing is performed through No. 3 clearing and brushing machine and No.4 clearing and brushing machine, so as to remove the ferric oxide on the surface of the band steel; and finally acid on the surface of the band steel is cleaned through the countercurrent rinsing device, the devices are reasonably connected, and the treatment process is good.
Description
Technical field
The utility model relates to a kind of pickler of stainless-steel sheet continuous annealing pickling unit.
Background technology
Stainless-steel sheet continuous annealing pickling unit is a unit with functions such as annealing, ball blast, pickling of producing 300000 tons per year.According to unit function and band steel processing sequence, unit can be divided into entrance, and process section and outlet section, process section mainly comprise operations such as annealing, ball blast, pickling, finish the art breading to the band steel.Pickler is finished pickling process, the whether reasonable quality that directly influences the stainless-steel sheet processing of its setting.
