Description
Technical field
The present invention relates to Hot Galvanizing Technology fields, and in particular to a kind of hot dip zinc-aluminium nickel tantalum alloy and the side of hot galvanizing
Method.
Background technique
Zinc is largely used as the corrosion protective layer of steel.Because there are big potential difference between steel and zinc layers, zinc
Rate of dissolution is very high.Hot-dip galvanizing sheet steel easily corrodes in a humid environment, make its surface formed white corrosion product or
Become grey dark-coloured, affects the presentation quality and coating corrosion resistance of hot-dip galvanizing sheet steel.
With the rapid development of the industries such as communication, electric power, automobile, ship, household electrical appliances, building, the need of hot-dip galvanized alloy product
The amount of asking is increasing year by year, and the requirement to product quality is continuously improved.The principle of hot-dip galvanized alloy are as follows: restored by pickling or atmosphere
Steel piece surface iron rust is cleaned up, then immerses in zinc liquid or be directly immersed in zinc liquid after solvent processing drying；
The iron of steel piece surface is reacted with fused zinc, forms alloy layer on steel construction piece surface.In order to reduce cost, improves hot galvanizing and produce
Corrosion resistance, surface characteristic and the good mechanical characteristic of product, while bottom ash yield is reduced, it reduces because salvaging bottom ash generation
Effective zinc waste, hot-dip galvanized alloy technology present new development trend.
It, by adding the alloy layer of trace alloying element, is made it have good in hot-dip galvanized alloy industry both at home and abroad at present
Good surface quality, excellent etch resistant properties and excellent binding performance and mechanical performance.But with changing for steel manufacturing process
Into raising, the ingredient of steel is complex, this variation causes traditional hot-dip galvanized alloy some galvanizing quality problems occur, such as
Coating super thick phenomenon, in uneven thickness, San Andreas Rift, color difference etc., while its generation bottom ash is more, and bottom is repeatedly salvaged in production
Slag wastes more effective zinc.On the other hand, structure is complicated for plating piece, and shape is changeable, such as big tower part, mostly uses siliceous
The higher steel of manganese, structure than single angle steel, channel steel, plate, band steel, steel pipe, different model complicated, the Ci Zhongjie such as strip
Structure influences the flowing of zinc-plated heat transfer and zinc liquid, influences the attachment of coating, puts forward higher requirements to hot-dip galvanized alloy.It is large-scale
Steel part and the steel part pickling time of complexity are long, can locally generate overpickling；Overpickling can bring more iron particles into and enter quickening liquid
In zinc liquid, impurity iron in galvanizing process zinc liquid is caused to increase, and generate more cadmias.This structural member simultaneously
Hot-dip requires high, and galvanizing time is needed to extend, and it is ineffective to be mainly manifested in zinc bath heat transfer in galvanizing process, zinc bath stream
Dynamic property is poor, and the more dissolved ferric irons of steel part enter zinc liquid, cause thickness of coating partially thick, and coating has color difference, and coating adhesion is poor, plating
The quality of coating problems such as layer is likely to occur particle, and not only light is clean for coating, and cadmia increases.In the prior art, common for heat
The kirsite of galvanized alloy mainly has Zn-Al alloy, Zn-Ni alloy, can not be suitable for the steel material surface of complicated ingredient
Hot plating technology cannot efficiently solve the problem of excessive iron particle enters the increase of cadmia caused by zinc liquid.Hot-dip is super
3 minutes are spent, is more than 200 μm since iron particle increases thickness of coating, brittle coating occurs, plating piece part poor adhesive force produces simultaneously
Raw more bottom ash cannot efficiently use to there is the zinc of 3-5% to waste.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of hot dip zinc-aluminium nickel tantalum alloys, with hot dip zinc
On the basis of the gross mass of aluminium nickel tantalum alloy, the hot dip is with containing Al, 0.01- of 0.1-25.0wt% in zinc-aluminium nickel tantalum alloy
The Ta of Ni, 0.01-0.5wt% of 2wt%, surplus are Zn and the inevitable impurity of kirsite institute band, are efficiently solved existing
Have in technology there are existing kirsite can not be suitable for complicated ingredient and structure the hot dip of steel material surface, zinc liquid iron
Particle increases and generates the technical issues of more bottom ash causes zinc to waste.
The present invention provides a kind of hot dip zinc-aluminium nickel tantalum alloy, on the basis of gross mass of the hot dip with zinc-aluminium nickel tantalum alloy,
The Ta of the hot dip Ni, 0.01-0.5wt% of Al, 0.01-2wt% in zinc-aluminium nickel tantalum alloy containing 0.1-25.0wt%, it is remaining
Amount is Zn and the inevitable impurity of kirsite institute band.
As further improvement of the invention, on the basis of gross mass of the hot dip with zinc-aluminium nickel tantalum alloy, the hot dip is used
The Ta of Ni, 0.01wt% of Al, 0.01wt% in zinc-aluminium nickel tantalum alloy containing 0.1wt%, surplus for Zn and kirsite institute band not
Evitable impurity.
As further improvement of the invention, on the basis of gross mass of the hot dip with zinc-aluminium nickel tantalum alloy, the hot dip is used
The Ta of Ni, 0.01wt% of Al, 0.01wt% in zinc-aluminium nickel tantalum alloy containing 25.0wt%, surplus are Zn and kirsite institute band
Inevitable impurity.
As further improvement of the invention, on the basis of gross mass of the hot dip with zinc-aluminium nickel tantalum alloy, the hot dip is used
The Ta of Ni, 0.5wt% of Al, 2wt% in zinc-aluminium nickel tantalum alloy containing 0.1wt%, surplus can not keep away for Zn and kirsite institute band
The impurity exempted from.
As further improvement of the invention, on the basis of gross mass of the hot dip with zinc-aluminium nickel tantalum alloy, the hot dip is used
