Abstract
One kind is used for steel wire electric card type heat treatment quantity-produced electrolytic phosphating process, and phosphating solution parameter is 55 78 points of total acidity, 68 points of free acidity, and nitrate radical content is 50 80g ∕ L.A diameter of 3.5 8.0mm steel wires make cathode after pickling, water rinsing, into steel wire, and the electrolytic cell that titanium makees anode carries out room temperature electrolytic phosphating, 6 10 peaces of cathode-current density/dm2, electrolysis time is according to take-up speed and electrolysis slot length control at 25 30 seconds.The present invention realizes good to the quick electrolysis phosphatization of steel wire, phosphate coat quality at normal temperatures.
Description
Technical field
One kind is used for steel wire electric card type heat treatment quantity-produced electrolytic phosphating process, belongs to metal product technology neck
Domain.
Background technology
At present, card electrothermal treatment phosphatization production line is generally using high temperature phosphorization, this kind of mode can only production specification it is small
In the steel wire of below 3.50mm, and normal temperature phosphating, there is also of poor quality, the technical problems such as phosphate coat is thin, also there are required phosphatization
Time is longer, takes up a large area, and phosphatization slag is more, containing heavy metal more not environmentally, need to heat the shortcomings of, use this electrolytic phosphating process
After the defects of having prevented common phosphating process.
The content of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of steel wire electric card type that is used for be heat-treated continuously
The electrolytic phosphating process of production, solution steel wire normal temperature phosphating is of poor quality, the thin technical problem of phosphate coat, improves steel wire electrolytic phosphating
Quality.
The present invention's is used for steel wire electric card type heat treatment quantity-produced electrolytic phosphating process：
Phosphating solution parameter is：Total acidity 55-78 points, free acidity 6-8 points, nitrate radical content are 50-80g ∕ L.
A diameter of 3.5-8.0mm steel wires make cathode after pickling, water rinsing into steel wire, titanium make the electrolytic cell of anode into
Row room temperature electrolytic phosphating, cathode-current density 6-10 peaces/dm2, electrolysis time is controlled according to take-up speed with electrolysis slot length to exist
25-30 seconds.
The present invention significantly improves the nitrate radical content of bonderite using the Phosphating Accelerant that compound protease etc. is produced, and reaches
Arrive at normal temperatures to the quick electrolysis phosphatization of steel wire.
The present invention is suitable for metal product power on heating steel wire heat treatment-pickling-room temperature electrolytic phosphating continuous lines and produces
Big specification wire is handled without slag phosphate coating.
Electrolytic phosphating liquid film forming speed of the present invention is fast, can form a film to 7-9g/m2 at 25-30 seconds and high temperature phosphorization needs 3-
8 minutes.The technique can produce the big specification wires of diameter 3.5-8.0mm after card electrothermal treatment.During using the technique productions, phosphating solution
It is not required to heat, does not produce sediment, no nickel, copper and nitrite are environmentally safe, have been truly realized both economically and environmentally beneficial.Through
The steel wire drawing speed of this production line production may be up to 93% up to 9m/s, total draught.
Embodiment
The present invention is described in detail exemplified by producing 3.5-8.0 millimeters of steel wire diameter：
The present invention's is used for steel wire electric card type heat treatment quantity-produced electrolytic phosphating process：
Phosphating solution parameter is：Total acidity 55-78 points, free acidity 6-8 points, nitrate radical content are 50-80g ∕ L.
A diameter of 3.5-8.0mm steel wires make cathode after pickling, water rinsing into steel wire, titanium make the electrolytic cell of anode into
Row room temperature electrolytic phosphating, cathode-current density 6-10 peaces/dm2, electrolysis time is controlled according to take-up speed with electrolysis slot length to exist
25-30 seconds.
Claims (1)
1. one kind is used for steel wire electric card type heat treatment quantity-produced electrolytic phosphating process, it is characterized in that：Phosphating solution parameter is：Always
