Abstract
The utility model discloses a backup rewashing device for a cold-rolled sheet pickling machine set. The device comprises a pickling tank set and a rinsing tank, which are arrayed fore-and-aft. The rinsing tank is connected with a water pipe having two control valves; a rinsing pump is arranged on the water pipe between the two control valves; the other end of the water pipe is communicated with an acid liquor jetting pipe located inside a first pickling tank; a wringing roller device is arranged on the steel inlet of the first pickling tank.
Description
Technical field
The utility model relates to the heavy cleaning device of a kind of cold rolled sheet pickling unit reversing, in order to the band steel is cleaned.
Background technology
In cold-rolled steel sheet was produced, each operation all can impact the surface quality of band steel.Wherein, pickling process is guide's operation of cold-rolled steel sheet production system, bearing and removing the belt steel surface hot rolling iron scale, for follow-up cold rolling process provides the task of the clean pickling raw material of high-quality coil of strip, guarantee that the finished product surface quality is good, pickling process stands in the breach.In process of production, stop if process section takes place, the band steel is stagnated in acid solution (and rinse water), and belt steel surface can generate rust staining rapidly, forms usually said " parking spot " defective, and its outward appearance is just as the metal bucket that gets rusty for many years.According to statistic data, exist the coil of strip of " parking spot " defective to account for the ratio of ultimate production coil of strip number generally about 7～8%.The band steel that has " parking spot " defective enters follow-up cold rolling process when rolling, and the oxide compound on surface part in the operation of rolling comes off, and is bonded in roller surface, causes the roll banding accident.Another part oxide compound can take the finished product operation to always, has a strong impact on the surface clearness of final finished.
The utility model content
The purpose of this utility model is to provide a kind of cold rolled sheet pickling unit reversing heavy cleaning device, can prevent effectively that acid solution rust staining defective from appearring in belt steel surface, improves strip surface quality.
The purpose of this utility model is achieved in that the heavy cleaning device of a kind of cold rolled sheet pickling unit reversing, comprise the pickling tank group and the rinse tank that are forward and backward arranged successively, on rinse tank, connecting a water pipe that has two control valves, the rinsing pump is installed on the water pipe between two control valves, the other end of water pipe is connected with the acid solution spray tube that is positioned at first pickling tank, in the band steel import of first pickling tank the squeezing roller device is installed.
When process section generation parking accident, the band steel is by withdrawing from backward in the pickling tank, on the one hand the rinsing pump causes in first pickling tank the acid solution to belt steel surface with the clear water in the rinse tank and cleans, prevent that acid solution is with steel band to go out pickling tank, by the squeezing roller device of installing in first pickling troughed belt steel import the moisture of belt steel surface is extracted on the other hand, and then will be with in the steel overlapping investment pickling tank and carry out pickling, the parking spot that belt steel surface is generated is heavily washed operation through reversing, eliminated, surface quality has reached standard-required.After accounting for " parking spot " defective elimination of total coil of strip several 7～8%, product percent of pass significantly rises.Eliminate acid solution that belt steel surface takes out of to the pollution of air in the workshop with to the corrosion of equipment steel construction frame, improved Working environment.The utility model is simple in structure, and technological transformation is with low cost, and is easy to use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a syndeton synoptic diagram of the present utility model.
Embodiment
The heavy cleaning device of a kind of cold rolled sheet pickling unit reversing, as shown in drawings, comprise the pickling tank group 7 and the rinse tank 8 that are forward and backward arranged successively, connecting a water pipe 3 that has two control valves 1,6 on rinse tank 8, said control valve 1,6 is acidproof pneumatic control valve.Adopt pneumatic control valve can improve the automatic control level of equipment.On the water pipe 3 between two control valves 1,6 rinsing pump 5 is installed, the other end of water pipe 3 is connected with the acid solution spray tube 4 that is positioned at first pickling tank.Rinsing pump 5 causes in first pickling tank the acid solution to belt steel surface with the clear water in the rinse tank 8 and cleans, and prevents that acid solution is with steel band to go out pickling tank.In the band steel import of first pickling tank squeezing roller device 2 is installed, squeezing roller device 2 is horizontally disposed, extracts in order to the moisture to belt steel surface, cleans so that will be with in the steel overlapping investment pickling tank.
Claims (2)
1, the heavy cleaning device of a kind of cold rolled sheet pickling unit reversing, comprise the pickling tank group (7) and the rinse tank (8) that are forward and backward arranged successively, it is characterized in that: on rinse tank (8), connecting a water pipe (3) that has two control valves (1,6), on the water pipe (3) between two control valves (1,6) rinsing pump (5) is installed, the other end of water pipe (3) is connected with the acid solution spray tube (4) that is positioned at first pickling tank, in the band steel import of first pickling tank squeezing roller device (2) is installed.
