Abstract
Provided is a method for manufacturing a galvanized steel sheet, wherein: a steel sheet is galvanized, the surface is exposed for 1 to 60 seconds to an aqueous solution with a pH of 4-6 and a temperature of 20-70 DEG C containing zinc ion with a concentration in the range of 5-100g/l, and then the steel sheet is washed and dried. An example of an ideal zinc-containing solution would be, for instance, a solution that contains zinc sulfate. The aforementioned method enables an oxide layer, mainly composed of zinc with an average thickness of no less than 10nm, to be formed on the surface of the steel sheet, thereby enabling a galvanized steel sheet with excellent press-formability to be manufactured in a stable manner and over a short period of time.
Description
Technical field
It is little and have the method for the zinc-based metal plated steel sheet of excellent extrusion molding to the present invention relates to a kind of slip opposing when stably making extrusion molding, and the zinc-based metal plated steel sheet with excellent extrusion molding.
Background technology
Zinc-based metal plated steel sheet is utilized in the wide spectrum that with the car body purposes is the center widely.Zinc-based metal plated steel sheet for such purposes is implemented extrusion molding, for use.But zinc-based metal plated steel sheet is compared the shortcoming with extrusion molding difference with cold-rolled steel sheet.Its reason is that the slip opposing of zinc-based metal plated steel sheet in extrusion mould is bigger than cold-rolled steel sheet.That is, the part that slip in mould and flange (PVC one De) opposing is big, zinc-based metal plated steel sheet is difficult to flow into mould and fracture that steel plate takes place easily.
At this, in zinc-based metal plated steel sheet, particularly, handling the hot dip alloyed zinc-based metal plated steel sheet of implementing Alloying Treatment in the back at the fusion electrogalvanized is that steel plate is compared with the molten zinc plating of not implementing Alloying Treatment, weldability and coating excellence, therefore more suitable as the car body purposes.
About hot dip alloyed zinc-based metal plated steel sheet, after steel plate enforcement electrogalvanized, carry out heat treated, Fe in the steel plate and the Zn in the coating spread and alloying reaction take place, and form the Fe-Zn alloy phase thus.This Fe-Zn alloy phase is generally the tunicle that is made of Γ phase, δ 1 phase, ζ phase, and along with Fe concentration reduces, that is, according to the order of Γ phase → δ 1 phase → ζ phase, there are the tendency that descends in hardness and fusing point.Therefore, consider from the viewpoint of sliding that high rigidity, high-melting-point and the high Fe concentration tunicle that is difficult to condense are effectively, the mean F e concentration that the hot dip alloyed zinc-based metal plated steel sheet of paying attention to extrusion molding is fabricated in the tunicle improves.
Yet the tunicle of high Fe concentration has the problem that occurs powdered easily, and so-called powdered is meant that hard and crisp Γ is formed at the interface of plating-steel plate mutually easily, adds the phenomenon of man-hour from interface peel.
As solution to the problems described above, disclose in patent documentation 1 and the patent documentation 2 by surface and implemented electrolysis treatment, dip treating, coating oxide treatment or heat treated, formed the technology that improves weldability, processibility based on the oxide film of ZnO at zinc-based metal plated steel sheet.
Yet, when the technology with patent documentation 1 and 2 is applied to alloy galvanized steel plate, because there is the A1 oxide compound in alloy galvanized steel plate, so the big and effect of the extrusion molding that can not stably be improved of surface reaction difference and concave-convex surface.That is,,, also be difficult to form the tunicle of regulation on the surface even therefore carry out electrolysis treatment, dip treating, coating oxide treatment and heat treated etc. because surface reaction is low, in the low part of reactivity, that is, and in the many parts of A1 oxide amount, thickness attenuation.In addition, because concave-convex surface is big, therefore the protuberance on surface directly contacts with extrusion mould when extrusion molding, and the part that thickness is thin in the protuberance becomes big with the slip of the contact part of mould opposing, and the effect of the extrusion molding that can not be improved fully.
Therefore, in patent documentation 3, disclose steel plate carried out the fused zinc plating after, carry out alloying by heat treated, after implementing skin pass rolling again, make it to contact, kept 1～30 second with acidic solution with pH shock absorption, wash, make oxide skin be formed at the technology on plating top layer thus.
Method as the portion that has an even surface of the fused zinc plated steel sheet that even oxide skin is formed at do not implement identical Alloying Treatment, the fused zinc coated steel sheet that discloses in patent documentation 4 after making skin pass rolling contacts with the acidic solution with pH shock absorption, then, under surface of steel plate forms the state of liquid film of acidic solution, keep washing after the specified time, the exsiccant method.

When using in above-mentioned patent documentation 3 and 4 disclosed technology, under creating conditions, can obtain good extrusion molding in the past.Yet, in recent years, wish to develop the manufacture method of the thicker oxide film of in shorter time generation in order to boost productivity, and when under condition like this, carrying out, adopt disclosed technology in the patent documentation 3,4, do not form sufficient oxide film sometimes and do not obtain good extrusion molding.
In view of correlation circumstance, the zinc-based metal plated steel sheet that the object of the present invention is to provide the manufacture method that can stably make zinc-based metal plated steel sheet at short notice and have excellent extrusion molding with excellent extrusion molding.
Summary of the invention
The inventor studies repeatedly with keen determination in order to solve above-mentioned problem.Consequently, obtain following result of study.
Employed acidic solution has the pH shock absorption because of promoting zinc dissolved purpose in the technology of patent documentation 3 and 4.Therefore think that pH rises slowly, the formation of oxide skin is slow.And, replenish the zinc that forms oxide skin owing to use, so comprise the dissolution time of zinc in the rise time of oxide film from the zinc of plating tunicle stripping.Consequently, think and be difficult to make thick oxide film to generate at short notice.
Therefore, the inventor works out by contain zine ion in advance in the aqueous solution that oxide film is generated and saved the zinc dissolution time, the technology that oxide film is generated in shorter time.Yet, only make and contain the formation that zine ion can not the promotes oxidn film in the aqueous solution in advance.Particularly, even in the pH2 treatment solution shown in the embodiment of patent documentation 3 and 4, contain zinc, there is not the formation of promotes oxidn film yet.
Its reason may be, in the technology of patent documentation 3 and 4, because simultaneous hydrogen ion reduction when the zinc stripping, therefore the pH of near surface rises and becomes the environment of easy generation zinc oxide, and if only make and contain zine ion in the aqueous solution, then the pH of near surface does not rise and can't form the environment of easy generation zinc oxide.
Therefore, inventor waits the technology that pH value of aqueous solution is decided to be pH4～6 that zinc oxide generates easily of having studied.Found that by pH value to be decided to be 4～6 with treatment solution, the zinc trace stripping of plating tunicle, small rising takes place in surface p H value, and zinc generates oxyhydroxide thus.
The present invention is based on above result of study and makes, and its main points are as described below.

Embodiment
In the present invention, after steel plate enforcement electrogalvanized, steel plate is contacted processing with the aqueous solution, the contact processing finishes after the back kept 1～60 second, washes, drying, when forming oxide skin on the zinc-based metal plated steel sheet surface thus, as aqueous solution, contain the zine ion that the zinc ion concentration scope is 5～100g/l, pH is 4～6, and the liquid temperature is 20～70 ℃.This shows, handle the aqueous solution of steel plate as contact, be made into the zine ion that contains normality and the aqueous solution of regulation pH and liquid temperature, this puts is important prerequisite in the present invention and is feature.Thus, can form sufficient oxide skin in order to ensure good extrusion molding at short notice.
Need to prove, be meant after so-called contact processing finishes, after expression dipping operation finishes under the situation of dip treating, after expression spraying operation finishes under the situation that spraying is handled, after the expression painting process finishes under the situation of roller coat cloth.
Handle the aqueous solution of steel plate as contact, contain the aqueous solution of zine ion, make the dissolution time of saving zinc become possibility by use.At this moment, as zinc ion concentration, the zine ion scope is 5～100g/l.The formation of oxide skin if less than 5g/l, then not supplying with competent zinc, zinc ion concentration does not take place.On the other hand, if surpass 100g/l, then the sulfuric acid concentration that contains in formed oxide skin uprises, and might be in the chemical combination treatment process of carrying out thereafter pollutes treatment solution during the dissolved oxygen thing.
Be used as oxide skin in order to form stable zn cpds, preferably zine ion added as vitriol.When adding, in formed oxide skin, introduce sulfate ion, be considered to have the effect that makes oxide skin stable as vitriol.
In addition, as previously mentioned, only make and contain the formation that zine ion can not the promotes oxidn film in the treatment solution in advance.Therefore, in the present invention, be necessary the pH value is decided to be pH4～6 that zinc oxide generates easily.If the pH of treatment solution is decided to be 4～6, the then zinc of plating tunicle trace stripping and the small rising of surface p H takes place generates the zinc as oxyhydroxide thus.As its result, saved the dissolution time of zinc, and, make the generation of zinc oxide become possibility.PH surpasses at 6 o'clock, and zine ion precipitation (oxyhydroxide formation) can not form oxide compound at surface of steel plate in the aqueous solution.In addition, pH as mentioned above, hindered the formation of oxide skin less than 4 o'clock owing to the pH rising delay.
About the temperature of the aqueous solution, be decided to be 20～70 ℃.Take place when keeping the specified time behind the aqueous solution for the formation that makes oxide skin is reflected to touch, the plate temperature control when keeping is effective in 20～70 ℃ scope.If less than 20 ℃, the formation reaction longer duration of oxide skin and cause productivity to reduce then.On the other hand, when surpassing 70 ℃, reaction compares fast, but surface of steel plate is handled spot easily on the contrary.
The feature of aqueous solutions employed is acid and has the pH shock absorption in the patent documentation 3 and 4.Yet, use the aqueous solution contain zine ion among the present invention, even the therefore pH height of the aqueous solution and zinc does not fully dissolve also can form sufficient oxide skin.And, think that the rising of pH takes place favourable for the formation of oxide compound fast.Therefore, the pH shock absorption might not be necessary.
In the present invention, if with contain zinc in the aqueous solution that surface of steel plate contacts, therefore then can stably form the oxide skin of excellent in sliding property,, also can not damage effect of the present invention even in the aqueous solution, contain or deliberately contain other metal ion, mineral compound etc. as impurity.So,, only just applicable otherwise damage effect of the present invention even N, P, B, Cl, Na, Mn, Ca, Mg, Ba, Sr, Si etc. are introduced in the oxide skin.
Make after the above aqueous solution that constitutes of zinc-based metal plated steel sheet contact, wish that this aqueous solution is present in surface of steel plate with the thin liquid film shape.This is because if the amount of the aqueous solution that surface of steel plate exists is many, even the dissolving of zinc then takes place, the pH of the aqueous solution also is difficult to rise, and needs long-time up to forming oxide skin.Consider from this viewpoint, the amount that is formed at the water-soluble liquid film of surface of steel plate is adjusted to 30g/m
2Below be preferred and effective.In addition, in order to prevent the purpose of liquid film drying, 5g/m
2Above liquid film amount is fit to.According to more than, be 5～30g/m preferably with the liquid film that is formed at surface of steel plate after aqueous solution contacts
2In addition, the adjusting of water-soluble liquid film amount can utilize extrusion roll, wind wiping (air wiping) to wait and carry out.
In addition, impregnated in the aqueous solution after, up to the washing time (up to the washing hold-time) be 1～60 second.If up to time of washing less than 1 second, then before forming sufficient oxide skin, the aqueous solution is washed off, therefore can not obtain to improve the effect of sliding.Hold-time when on the other hand, surpassing 60 seconds causes productivity to descend.Even purpose of the present invention be at short notice also can be stable manufacturing, therefore consider that from the viewpoint of giving full play to effect of the present invention the hold-time is below 60 seconds.
By more than, it is the oxide skin more than the 10nm as main body, the mean thickness of metal ingredient that the surface of steel plating plate of the present invention obtains to contain zinc.
Wherein, so-called zinc is that main body is meant as metal ingredient, contains the above zinc of 50 quality %.
Wherein, the oxide skin among the present invention is meant by containing the layer that zinc constitutes as the oxide compound of the main body of metal ingredient and/or oxyhydroxide etc.The mean thickness of this oxide skin is necessary more than 10nm.If the mean thickness of oxide skin is as thin as less than 10nm, the effect that the opposing of sliding is descended is insufficient.On the other hand, surpass 100nm if contain zinc as the mean thickness of the oxide skin of essential composition, the opposing of then being slided by film destroy in extrusion processing is risen, and the tendency that exists weldability to descend, and is therefore not preferred.
Wherein, be not particularly limited for making zinc-based metal plated steel sheet contact contain the method that the zinc aqueous solution handles, the method that makes the steel plating plate impregnated in the aqueous solution is arranged, the aqueous solution is sprayed on method on the steel plating plate, the aqueous solution is situated between coats method on the steel plating plate etc. by coating roll, wish finally to be present in surface of steel plate with the thin liquid film shape.
In addition, about the manufacturing of alloy galvanized steel plate of the present invention, it is necessary adding Al in plating bath, but does not limit especially for the interpolation elemental composition beyond the Al.That is, even contain beyond the Al or add Pb, Sb, Si, Sn, Mg, Mn, Ni, Ti, Li, Cu etc., so long as it is just applicable not damage effect of the present invention.
