Description
Technical field
The present invention relates to pretreating device in continuous galvanizing line, especially a kind of zinc-plated pre-treatment section acid dip pickle.
Background technology
Resting period, longer cold-rolled strip surface can get rusty, and the position got rusty when zinc-plated can not plate zinc, produce plating leakage
Defect；Generally acid dip pickle is set to get rid of the iron rust on cold-rolled strip in preceding processing section in galvanization production line, it is known that
Acid dip pickle typically has following defect：First, acid solution is slack-off with the time of iron rust generation chemical change when low temperature, causes
The derusting of winter acid solution is less able；2nd, when one layer of greasy dirt is covered on iron rust, acid solution and iron rust contact area are few,
Derusting is not thorough；3rd, acid solution is brought into follow-up electrolytic cell by steel band after acid dip pickle, causes electrolytic cell to be corroded.
The content of the invention
Deficiency, it is an object of the invention to provide a kind of zinc-plated pre-treatment section acid dip pickle, includes heating for more than
Case, acid cleaning tank, rinse tank and air knife, the iron rust on cold-rolled strip can be effectively got rid of rapidly and avoids acid solution to follow-up frock
Corrosion.
The technical scheme is that be accomplished by the following way：A kind of zinc-plated pre-treatment section acid dip pickle, includes
Heater box, acid cleaning tank, rinse tank and air knife, upper and lower in described heater box is each provided with one group of natural gas nozzle, described
The left side in acid cleaning tank is provided with some groups of acid solution jet pipes and brush roll, and the right is provided with acid solution squeeze roll；Described rinse tank
The interior left side is provided with some groups of nature water spray pipes, and the right is provided with water squeeze roll；It is characterized in that：A left side for described acid cleaning tank
End is provided with the heater box of built-in natural gas nozzle, and right-hand member is then provided with rinse tank.
Described air knife is arranged on the exit of rinse tank, and specular is distributed in steel band both sides up and down.
The present invention is jetted out flames by the natural gas nozzle in heater box to burn up greasy dirt and heats cold-rolled strip, then leads to again
Iron rust is thoroughly got rid of in acid solution jet pipe in peracid tank-washer and brush roll combination, finally by rinse tank by the acid in steel strip surface
Liquid cleans up, and has not only effectively got rid of the iron rust of steel strip surface, it is thus also avoided that the follow-up electrolytic cell of acid liquid corrosion.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
1 is heater box in figure, and 2 be acid cleaning tank, and 3 be rinse tank, and 4 be natural gas nozzle, and 5 be acid solution jet pipe, and 6 be hairbrush
Roller, 7 be acid solution squeeze roll, and 8 be nature water spray pipe, and 9 be water squeeze roll, and 10 be air knife, and 11 be steel band.
Embodiment
Known by Fig. 1, a kind of zinc-plated pre-treatment section acid dip pickle, include heater box 1, acid cleaning tank 2, rinse tank 3 and air knife
10, described heater box 1, acid cleaning tank 2 and rinse tank 3 are from left to right arranged in order；Setting each up and down in described heater box 1
Have one group of natural gas nozzle 4, jet out flames burn-up steel band 11 on greasy dirt and steel band 11 is heated, described acid cleaning tank 2
The interior left side is provided with some groups of acid solution jet pipes 5 and brush roll 6, and the right is provided with acid solution squeeze roll 7；In described rinse tank 3
The left side be provided with some groups of nature water spray pipes 8, the right is provided with water squeeze roll 9；Described air knife 10 is arranged on rinse tank 3
Exit, and about 11 both sides for the steel band that is distributed in of specular.
During work, steel band 11 is entered in heater box 1 from the left side, and the natural gas nozzle 4 in heater box 1 jets out flames burning
Fall the greasy dirt of the upper and lower surface of steel band 11, while also heated steel band 11；Steel band 11 enters acid cleaning tank 2 after being come out from heater box 1,
The acid solution jet pipe 5 on the left side sprays acid solution and scrubbed to the upper and lower surface of steel band 11, then by brush roll 6 in acid cleaning tank 2, accelerates acid solution
With the chemical reaction of iron rust；After some groups of acid solution jet pipe 5 and the pickling of brush roll 6, the iron rust quilt on the surface of steel band 11
It is quick to remove, then squeezed out by acid solution squeeze roll 7 and rinse tank 3 is delivered to after a large amount of acid solutions on steel band 11, the left side in rinse tank 3
Some groups.Natural water spray pipe 8 sprays substantial amounts of Natural Water and washes acid solution remaining on the surface of steel band 11, then passes through water
Squeeze roll 9, which extracts the acid solution of low concentration on steel band 11, transfers out rinse tank 3, and the air knife 10 in the exit of rinse tank 3 blows out high pressure
Air, further by sour water scraped clean remaining on steel band 11.
The present invention is jetted out flames by the natural gas nozzle 4 in heater box 1 to burn up greasy dirt and heats cold-rolled strip 11, then
Combined again by the acid solution jet pipe 5 in acid cleaning tank 2 and brush roll 6 and thoroughly get rid of iron rust, finally by rinse tank 3 by steel band 11
Acid solution on surface cleans up, and has not only effectively got rid of the iron rust on the surface of steel band 11, it is thus also avoided that acid liquid corrosion is follow-up
Electrolytic cell.
