Abstract
The present invention is the phosphorization treatment process before a kind of high-carbon steel wire rod pickling free drawing, is comprised the step of：Salt pickling, water rinsing, high pressure water washing, phosphatization, washing, saponification and drying.Wherein phosphating solution by 10~22g/L Zn (H2PO4)2, 15~25g/L Zn (NO3)2Compound accelerant with 3~5g/L is with 4:4:1:1 volume ratio, which coordinates, to be formed.The general phosphating coat that phosphorization treatment process before a kind of high-carbon steel wire rod pickling free drawing of the present invention is formed has the advantage that:(1) there is certain bond strength with steel matrix, will not be destroyed before drawing film is entered or in drawing film；(2) there is certain heat resistance；(3) there is enough plasticity；(4) it is easy to adsorpting lubrication agent；(5) easily removed in heat treatment clean；(6) there is certain rustless property；(7) there is neutralization to Steel Wire Surface remaining acid solution.
Description
Technical field
The present invention relates to high-carbon steel disk pickling free drawing technology field, more particularly to a kind of high-carbon steel wire rod pickling free drawing
Preceding phosphorization treatment process.
Background technology
Phosphatization is a kind of conventional metal surface treatment process, is widely used in the painting of the lubrication before medium and high carbon steel wire rod drawing
Layer.Its operation principle is wire rod surface under the chemistry of phosphating solution and electrochemical action, is formed one layer thin based on phosphate
Film, the microstructure of this layer of phosphate film can make lubricant be attached to hole into porous in follow-up drawing process
In, so that forming lubricating film between steel wire matrix and drawing mould, play good lubricant effect.Wire rod phosphorating treatment quality
Quality will directly affect steel wire drawing quality, yield and cost, therefore it is required that the phosphating coat of wire rod Surface Creation have it is certain
Thickness, there is good adhesion, surfaces versus rough, so as to the adsorpting lubrication agent in follow-up drawing, be loaded into mould, shape
Into lubricating film.
Therefore, designing the phosphorization treatment process before a kind of high-carbon steel wire rod pickling free drawing, solves problem above.
The content of the invention
The present invention is to overcome the above insufficient, there is provided the phosphorization treatment process before a kind of high-carbon steel wire rod pickling free drawing, bag
The step of including has：Salt pickling, water rinsing, high pressure water washing, phosphatization, washing, saponification and drying.
Wherein phosphating solution by 10~22g/L Zn (H2PO4)2, 15~25g/L Zn (NO3)2With 3~5g/L compound rush
Enter agent with 4:4:1:1 volume ratio, which coordinates, to be formed；
Phosphatization temperature is controlled at 65-70 DEG C；
Phosphating time is controlled in 12-14min.
Further, the phosphatization temperature control is at 68 DEG C；
Preferably, phosphating time control is in 13min.
The beneficial effects of the invention are as follows：
The general phosphating coat tool that phosphorization treatment process before a kind of high-carbon steel wire rod pickling free drawing of the present invention is formed
There is following advantage:
(1) there is certain bond strength with steel matrix, will not be destroyed before drawing film is entered or in drawing film；
(2) there is certain heat resistance, do not destroyed by high speed drawing；
(3) there is enough plasticity, can extend with steel wire, be attached to all the time in Steel Wire Surface；
(4) it is easy to adsorpting lubrication agent；
(5) easily removed in heat treatment clean；
(6) there is certain rustless property, without other adverse effects；
(7) there is neutralization to Steel Wire Surface remaining acid solution.
Embodiment
It is described in detail below with reference to embodiments of the invention.
A kind of phosphorization treatment process before high-carbon steel wire rod pickling free drawing, is comprised the step of：Salt pickling, water rinsing,
