Abstract
The invention discloses a pickling process of steel wire. The pickling process comprises the following steps: 1) preparation before pickling: wire breaking; 2) pickling: under room temperature, the steel wire is immersed for about 15 minutes in a hydrochloric acid pool; 3) high-pressure water washing: introduction of residual hydrochloric acid in a phosphatization pool can be avoided; 4) phosphatization: the phosphatization temperature is 50-70 DEG C, the phosphatization time is 8-15 minutes, during phosphatization, a valve in a saponification pool is closed, and the valve in a phosphatization pool is opened; 5) detection: the surface condition of the steel wire after phosphatization is detected, the color is grey or dark grey; a phosphatization film is fine and firm without rust; 6) high-pressure water washing: introduction of residual phosphatization liquid in the saponification pool can be avoided; during the process, the valve in the phosphatization pool is closed, and the valve in the saponification pool is opened; and 7) saponification: the saponification temperature is 75-85 DEG C, and the saponification time is 2-5 minutes. The pickling process has the advantage of simple steps, can obviously increase the efficiency, and has good pickling effect.
Description
Technical field
The present invention relates to a kind of steel wire acid cleaning process.
Background technology
Steel wire is a kind of very conventional mechanical part, one pickling process is had during Production for Steel Wire, the pickle of acid cleaning process is generally the mixture of multiple acid, the method utilizing acid solution to remove the oxide skin on steel surface and corrosion thing is referred to as pickling, it is a kind of method of cleaning metal surface, generally carries out together with pre-film.In the manufacturing of steel wire, current acid cleaning process flow process is complicated, causes productivity underground.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of steel wire acid cleaning process, and this technological process is simple, can significantly improve efficiency, and pickling effect is good.
For achieving the above object, the invention provides a kind of steel wire acid cleaning process, it is characterised in that, comprise the steps: 1) preparation before pickling: broken line, i.e. cut off unnecessary strap, only leave one according to tying up stringcourse, make wire rod uniformly scatter, and hang up label on stringcourse tying up；2) pickling: under room temperature, soaks about 15 minutes in hydrochloric acid pond, and in the process constantly with steel wire agitation acid pond, in order to accelerate pickling speed, accomplish non-oxidation iron sheet；3) high pressure water washing: avoid the hydrochloric acid of remnants to enter phosphating pond；
4) phosphatization: phosphatization temperature: 50 ~ 70 DEG C, phosphating time: 8 ~ 15 minutes, it should be noted that the valve closed in saponification pond while phosphatization, open the valve in phosphating pond, for improving production efficiency, the raw material pickling of same lot number or heat (batch) number should be hung；5) inspection: the surface condition of steel wire after inspection phosphatization, its color is Lycoperdon polymorphum Vitt or lead.Phosphating coat should be fine and closely woven, firm, without rusty stain；6) high pressure water washing: avoid the Phosphating Solution of remnants to enter in saponification pond, and in the process, close phosphating pond valve, open saponification pond valve；7) saponification: saponification temperature 75 ~ 85 DEG C, saponification time: 2 ~ 5 minutes.After saponification, the surface of steel wire is one layer of milky film layer of band.
The invention has the beneficial effects as follows: present invention process flow process is simple, can significantly improve efficiency, and pickling effect is good.
Detailed description of the invention
Technical scheme disclosed by the invention is a kind of steel wire acid cleaning process, it is characterised in that comprise the steps: 1) preparation before pickling: broken line, i.e. cut off unnecessary strap, only leave one according to tying up stringcourse, make wire rod uniformly scatter, and hang up label on stringcourse tying up；2) pickling: under room temperature, soaks about 15 minutes in hydrochloric acid pond, and in the process constantly with steel wire agitation acid pond, in order to accelerate pickling speed, accomplish non-oxidation iron sheet；3) high pressure water washing: avoid the hydrochloric acid of remnants to enter phosphating pond；4) phosphatization: phosphatization temperature: 50 ~ 70 DEG C, phosphating time: 8 ~ 15 minutes, it should be noted that the valve closed in saponification pond while phosphatization, open the valve in phosphating pond, for improving production efficiency, the raw material pickling of same lot number or heat (batch) number should be hung；5) inspection: the surface condition of steel wire after inspection phosphatization, its color is Lycoperdon polymorphum Vitt or lead.Phosphating coat should be fine and closely woven, firm, without rusty stain；6) high pressure water washing: avoid the Phosphating Solution of remnants to enter in saponification pond, and in the process, close phosphating pond valve, open saponification pond valve；7) saponification: saponification temperature 75 ~ 85 DEG C, saponification time: 2 ~ 5 minutes.After saponification, the surface of steel wire is one layer of milky film layer of band.
Present invention process flow process is simple, can significantly improve efficiency, and pickling effect is good.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
