Specific implementation mode
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, builds according to normal condition or manufacturer
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
Galvanized sheet provided in an embodiment of the present invention and its production method are specifically described below.
The embodiment of the present invention provides a kind of galvanized sheet, and production method mainly includes the following steps that：
The preparation of zinc-base plate to be plated.It is to be appreciated that the substrate of patterned can be by other producers provide can direct plating
The finished product of zinc can also be to be prepared in situ to meet the substrate of necessary requirement (such as the offline embossing in scene, galvanizing unit are embossed online
Deng), it is further continued for carrying out zinc-plated processing.
Decorative pattern on substrate generally can be embossed processing to substrate by planisher and be formed, and embossing effects are good, production
It is efficient.The mesh that different flower pattern are extruded on substrate can be realized by replacing the working roll with different decorative patterns on planisher
's.It is of course also possible to use embossing machine, laser engraving, hand engraving, other equipment or other modes with embossing function
Decorative pattern is formed on substrate.
Before substrate surface makes decorative pattern, it may further ensure that the surface roughness Ra of substrate is less than or equal to 5 microns.
Surface roughness refers to the unevenness of smaller spacing and small peak valley that finished surface has.Surface roughness is smaller, then surface
It is more smooth.Base plate surface roughness preceding road roll or smooth process in formed, by rolling or smooth process working roll
It is generated in surface roughness " duplicating " to substrate.Work roll surface roughness be usually by used processing method and other because
Element is formed by, such as the plasticity of superficial layer metal becomes when friction, the chip in process between cutter and piece surface detach
High-frequency vibration etc. in shape and process system.Due to the difference of processing method and workpiece material, surface to be machined is left a trace
The depth, density, shape and texture have difference.Before substrate manufacture decorative pattern, smaller roughness advantageously ensures that the later stage
The uniformity that decorative pattern is formed is conducive to the uniformity for improving zinc coating.
The shape of decorative pattern may include one kind or more in network, rectangular mesh, polygonal mesh, special-shaped grid
Kind.It is of course also possible to use other decorative pattern forms with certain barrier effect, such as strip pattern, it is spaced apart in substrate surface
If multiple strip patterns.After strip pattern is opened in substrate surface, it is observed that strip pattern is formed by bar-shaped trough, the width of bar-shaped trough
Degree and depth can be modified according to specific requirements.Strip pattern can be opened up along the length or width direction of substrate, to ensure
The barrier effect of strip pattern, make during board transport transmission direction and strip pattern to open up direction vertical.
The formation of decorative pattern necessarily makes substrate surface there are multiple protrusions, and there are recessed portions between adjacent protrusion.Further
Ground, raised width are 2-10 millimeters, and the width of recessed portion is 50-100 millimeters.When substrate takes out from zinc liquid, zinc liquid is attached
It in substrate surface, and is filled with the recessed portion in decorative pattern.Generally continue along vertically upward when being taken out from zinc liquid due to substrate
Direction movement, at this time the extra zinc liquid of substrate surface will be trickled downwards due to gravity.Projection portion in decorative pattern will hinder
Gear zinc liquid freely trickles, and coating thicker, evenly is obtained convenient for user.The width of protrusion and the width needs of recessed portion
With suitable, it can just make the distribution of zinc liquid more uniform, it is more preferable to the antitrickle effect of zinc liquid.For example, if recessed portion is wide, raised mistake
Narrow, then protrusion possibly can not preferably prevent zinc liquid stream from dropping down.
The projection thickness (i.e. height) that decorative pattern is formed is typically greater than or equal to 10 microns, and target coating is thicker, then requires to spend
The height of line protrusion is also bigger.To ensure to play preferable antitrickle effect to zinc liquid, the thickness increase effect of zinc coat is more preferable.
Further, it is the uniformity of guarantee coating, raised thickness is generally less than zinc coating thickness required on substrate.It is convex
It plays thickness to cross conference and cause final coating that cannot be fully filled with and cover the decorative pattern on substrate, the decorative pattern of substrate can be highlighted instead
Profile does not meet the appearance requirement of galvanized sheet；It is too small, it can not effectively stop freely trickling for thickness coating zinc liquid, zinc can not be eliminated
Flow liner.Therefore, it is necessary to the target thickness of coating according to required production, determine the decorative pattern projection thickness of raw material substrate.Certainly, if certain
A little users need to embody specific decorative pattern on the steel plate, and raised thickness can also be slightly larger than zinc coating thickness required on substrate.
In traditional handicraft, generally there are zinc flow liners for coating surface.Zinc flow liner is also known as zinc wave defect, refers in steel strip surface shape
At the wave strip crystal crack with traffic direction generally vertically.Being formed as in galvanizing process for zinc flow liner, works as strip
(zinc-plated substrate) from zinc liquid out, when running vertically upward, be attached to belt steel surface does not solidify zinc liquid, because coating is too
Thickness, and zinc fluid viscosity is not enough to overcome coating weight, leads to zinc liquid to trickle along plate face and generate uneven leaching to hang.The present invention is real
It applies in example, the setting of decorative pattern greatly reduces the probability of zinc flow liner appearance on substrate, and then also prevents zinc flow liner to galvanized sheet
The adverse effect brought, for example, uniformity to the uniformity, the consistency of Deposit appearance, zinc of thickness of coating flower influence.
In other embodiments of the invention, the surface of substrate can also be increased by the way of carrying out frosting treatment to substrate
Roughness makes the surface after texturing that can also play antitrickle effect to zinc liquid, to increase galvanized layer thickness.Texturing mode can
With using one kind in common shot-peening texturing, electric spark texturing, electron beam texturing, laser roughening.
After substrate is ready, you can carry out zinc-plated processing.
The transmission speed that substrate passes through zinc liquid is 20-200 ms/min.Into before zinc liquid, the temperature of substrate is 420-460
DEG C, the temperature of zinc liquid is 450-470 DEG C.
Wherein, zinc liquid includes aluminium and antimony, and the content of aluminium is 0.18-0.22wt%, and the content of antimony is 0.07-
0.08wt%.The corrosion resistance that suitable metallic element can effectively improve substrate is added in zinc liquid, while can also be reached
Improve the effect of quality of coating.
In galvanizing process, aluminium can react to form one layer of fine and close iron aluminide film with iron, inhibit the diffusion of iron, from
And make the formation of iron zinc compound layer and thicken to receive obstruction；Meanwhile aluminium can cement out the iron in cadmia, form aluminium zinc
Compound removes to which cadmia float.A small amount of aluminium is added in zinc liquid, protective oxide film can be formed, to obviously subtract
The oxidation on light zinc liquid surface, reduces the loss of zinc liquid, greatlys save cost.
Aluminium is also beneficial to finished product galvanized sheet.Aluminium can improve the adhesive force of coating, and iron aluminide layer can play matchmaker
The effect of Jie, makes base steel be closely linked with coating, will not in deformation to improve the punch forming ability of galvanized sheet
Coating is caused to fall off.
Antimony can not only promote coating surface to form zinc flower, and can remarkably promote the growth of big zinc flower.In heat galvanizing liquid, antimony
The mobility of zinc liquid can also be improved and reduce the surface tension of substrate surface liquid Zn, keep coating evenly smooth.
The content of aluminium and antimony is required for strictly being controlled according to production requirement, excessive or very few be unable to reach preferable effect
Fruit.
Substrate purges the substrate for leaving zinc liquid using air knife after being spread out of in zinc liquid.Liquid level of the air knife away from zinc liquid
Height is 300-600 millimeters.Air knife is 80-120 millimeters at a distance from substrate.The wind pressure of air knife is 40-60kPa.The peace of air knife
Holding position, air knife wind pressure have an impact to the formation of coating, user requires according to actual production, appropriate to adjust air knife.
Air knife knife gap is also closely related with thickness of coating, generally requires the knife gap among air knife smaller, extends to two side tools
Gap gradually increases.In the embodiment of the present invention, intermediate knife gap is 0.6-1 millimeters, and the knife gap of edge is 0.8-
1.3 millimeter.
Protective effect of the Zinc coat to internal substrate steel sheet of strip hot-dip galvanizing product utilization, corruption in an atmosphere
Erosion is mainly electrochemical corrosion.Zinc coat is dissolved as anode in electrochemical corrosion, and substrate steel sheet is obtained as cathode
Protection is not corroded.The zinc coat thinned speed that is corroded is related with atmospheric environment, and under the conditions of equal ambient, galvanized sheet
Resistance to service life is directly proportional to the thickness of zinc coat, therefore thickness of coating is one of the important parameter of strip hot-dip galvanizing product.
It is provided in standard GB/T/T2518-2008, the coating ranging from 60-600g/m of strip hot-dip galvanizing steel plate2(two-sided), wherein
60-275g/m2Coated article be conventional products, more than 275g/m2Be super thick coated article.It is carried using the embodiment of the present invention
The method of the substrate production galvanized sheet using patterned supplied, can not only ensure that the coating quality of conventional products is more preferable, moreover it is possible to
Enough simplify the processing method of super thick coated article, and ensures that the coating quality of super thick coated article is more preferable.
The feature and performance of the present invention are described in further detail with reference to embodiments.
