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

The stainless-steel sheet pickler
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.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of the stainless-steel sheet pickler that treatment effect is good is set rationally.
Technical scheme: stainless-steel sheet pickler described in the utility model, comprise the pickling tank unit, described pickling tank unit comprises sulfuric acid section and nitration mixture section, is provided with cleaning and brushing machine between sulfuric acid section and the nitration mixture section; Be disposed with pre-flushing arrangement, cleaning and brushing machine and countercurrent rinsing device after the nitration mixture section.
Be provided with pre-spray equipment before the described sulfuric acid section.
Described nitration mixture section is two sections, is respectively 1 section nitration mixture section and 2 sections nitration mixture sections.
Cleaning and brushing machine between sulfuric acid section and the nitration mixture section is two, is respectively No. 1 cleaning and brushing machine and No. 2 cleaning and brushing machines.
Cleaning and brushing machine after the nitration mixture section is two, is respectively No. 3 cleaning and brushing machines and No. 4 cleaning and brushing machines.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: the pickler in the utility model stainless-steel sheet continuous annealing pickling unit is rationally distributed, ferric oxide by pre-spray equipment flushing belt steel surface, carry out pre-pickling by the sulfuric acid section, by 2 cleaning and brushing machines the band steel is carried out the water flushing, remove surface oxidation iron, the requirement of strip speed when satisfying pickling by two sections nitration mixture sections, remove belt steel surface acid and impurity by pre-flushing arrangement, by 3, No. 4 cleaning and brushing machine carries out the water flushing, removes surface oxidation iron, passes through the acid of countercurrent rinsing device flush away belt steel surface at last, each device is connected rationally, and treatment effect is good.
