Description
Technical field
The present invention relates to steel strand wires manufacturing field, more specifically to a kind of prestress wire be aerated pickling tube and
Acid washing method.
Background technology
It needs to heat because of rolling in the wire raw material wire rods of prestress wire industry, can all there be one layer of iron chloride on last surface
Skin, so surface chlorination iron sheet pickling will be fallen with hydrochloric acid or sulfuric acid before drawing.Wire rod is reacted in pickling tube, and one by dense
Degree, two lean on the time, and three with acid solution surface by coming into full contact with.Wire rod now to factory is all that manufacturer is fully urgent with steel wire
Bundle, convenient for the transport of next step, if solving bundle before pickling, wire rod unclamps, and sufficiently bulky, sour pond must be built very big, turns after washing
To next procedure transport difficult.It does not understand such as and ties, it is clean because of very tightly, being difficult to wash between wire rod gap, cause next procedure
Drawing is difficult.Current most of producers all do not understand bundle, take and extend pickling time to solve.
It is stirred in existing pickling tube pickling tube multipair greatly, to increase the flow velocity in pickling tube, accelerates pickling reaction,
Chinese patent application, application number 201310212602.9, disclose a kind of pickling tube at publication date on November 27th, 2013, including
Acid bath, several disturbance plates and disturbance plate driving mechanism, the disturbance plate under the drive connection of disturbance plate driving mechanism
It is reciprocating in the acid bath.The present invention by disturbance plate being set to accelerate the mobility of acid solution in pickling tube, so as to
The compound for being conducive to metal surface is diffused in acid solution, then accelerates pickling process, improves pickling efficiency.This pickling tube
Only the acid solution in pickling tube is stirred, with this acid solution is come into full contact with, substance is not carried out in pickling efficiency carries
Height, reaction are not enough, and acid solution consumption is still bigger.
Invention content
1. technical problems to be solved
For it is in the prior art be difficult to wash clean, transport difficult, pickling tube it is big, it is inefficient, consumption acid solution it is more
The problem of, the present invention provides a kind of prestress wire aeration pickling tube and acid washing methods, it can realize cleaning steel strand wires
Clean abundant, the simple target of transport, required pickling tube is small, pickling is efficient, acid solution consumption is few.

Equipment uses in wash pool.
Further, the solarization air cap aperture is 5mm, and distance is 10mm between adjacent holes.
Further, it is 0.6Mpa that the compressed air pump, which generates air pressure,.
A kind of acid washing method using the prestress wire aeration pickling tube, its step are as follows：
A the hydrochloric acid of mass concentration 18%-21%) is added in pickling tube, the steel strand wires tied up are placed in inside pickling tube；
B) compressed air pump connection aeration tube opens compressed air pump, and adjusting air pressure is 0.6Mpa, and aeration tube is led to
Gas, aeration inner air tube are overflowed by solarization air cap, accelerate acid solution flowing in pickling tube；
C) by the 8min times, steel strand wires are taken out, the oxide layer of steel strand surface is removed；
D) using high-pressure pump to step C) steel strand wires of removing oxide layer is gone to rinse, remove the residual acid of steel strand surface；
E) phosphatization：Steel strand wires are carried out with middle temperature phosphating, temperature is 60-80 DEG C, the ratio of solution free acidity and total acidity
It is 1：(6-10), total acidity 35-60 " point ", steel strand surface adsorb one layer of phosphating coat；
F) boronation：Use the borax neutralization procedure E of a concentration of 10%-30%) treated the residual acid of steel strand surface, it is conducive to
Lubricity during drawing.
Further, at 80 DEG C -90 DEG C, solution temperature height is conducive to the residual of steel strand surface the boronation temperature
Acid carries out adequately neutralizing, increase borax solubility in water and the uniformity and improving the surface temperature of steel strand wires after coating
And it is easy to dry.
3. advantageous effect
Compared with the prior art, the advantage of the invention is that：
(1) steel strand wires pickling is carried out using this pickling tube, steel strand wires are tied without solving, and pickling tube can be a little bit smaller with volume.Such as
The area that fruit originally solves bundle pond is 12m2, not understanding bundle pool area only needs 6m2, depth is constant, and hydrochloric acid dosage can save half,
It can reach identical effect；
(2) pickling pool area reduces, and the volatilization of acid solution is reduced, and acid solution utilization rate is high, saves acid solution；
(3) aeration tube is used so that acid solution is fully contacted with wire rod, surface acid-washing is perfect, and drawn steel wire quality is preferable, acid
It is good to wash effect；
(4) acid solution can be caused with reacting rapider efficiency more when wire rod haptoreaction with the compressed air of aeration tube
Height, pickling time reduce, and efficiency increases.
