Abstract
A kind of water-soluble fluxing agent of iron and steel hot dip aluminum plating or alloy plating, form by the aqueous solution that contains potassium chlorate fluozirconate, Repone K, aluminum fluoride, Potassium monofluoride and hydrofluoric acid, be characterized in that steel surface is had stronger activation, the liquid of aluminizing, aluminized products are not all produced deleterious effect, and the plating assistant agent component can be dry under comparatively high temps after not evaporating, do not wear out, help plating to handle.
Description
The invention belongs to in the flux method iron and steel hot dip aluminum plating formula aluminium alloy technological process, help the used a kind of water-soluble fluxing agent of plating treatment process.
In with flux method hot dip aluminum plating (or aluminium alloy) technological process, earlier the iron and steel plating piece is flooded appropriate time in water-soluble fluxing agent, after the proposition drying, immersion plating in molten aluminum liquid again.The currently used water-soluble fluxing agent of this technology (concentration of each composition be weight percentage concentration) has:
(1) contains ZnCl
240% the aqueous solution;
(2) contain ZnCl
232%, NH
4The aqueous solution of Cl8%;
(3) contain ZnCl
232%, PbCl
21%, the aqueous solution of HCl10%;
(4) contain K
2ZrF
620% the aqueous solution.
(1), (2) or (3) plant aqueous solution plating assistant agent since when dip calorizing ZnCl
2With aluminium generation chemical reaction, generate aluminum chloride gas and metallic zinc, thereby the gas that is produced can make by plated steel material surface local plating not, the zinc particle that is perhaps produced influences the use properties of aluminum steel attached to the aluminium coated surface.Therefore, contain ZnCl
2Water-soluble fluxing agent, its help the plating effect not ideal enough.And (4) plant aqueous solution plating assistant agent, though help the plating effect better, because of K
2ZrF
6The price height, cause the cost of generation to improve.
Based on the weak point of existing water-soluble fluxing agent, the present invention desires to provide a kind of and helps that plating is effective, cost is low, and is suitable for the used water-soluble fluxing agent of flux method iron and steel hot dip aluminum plating (or aluminium alloy) of suitability for industrialized production.
For achieving the above object, water-soluble plating aid for hot immersion aluminum-plating provided by the invention, its proportioning consists of:
K
2ZrF
6(potassium chlorate fluozirconate) 40～80 grams per liters
KCl(Repone K) 16～40 grams per liters
AlF
3(aluminum fluoride) 2～18 grams per liters
The KF(Potassium monofluoride) 0～20 grams per liter
HF(hydrofluoric acid) 0～10 milliliter/liter
During above-mentioned proportioning was formed, the weight percent concentration of hydrofluoric acid in 40% was.
When using water-soluble fluxing agent provided by the invention to carry out hot dip aluminum plating or hot dip aluminum plating alloy, steel or the goods that to cross through degreasing, cleanup acid treatment, be immersed in the water-soluble fluxing agent of certain temperature, behind appropriate time, take out, and dry down about 300 ℃, immerse in the molten aluminum liquid then.Use this water-soluble fluxing agent, steel surface must clean, and the temperature of plating assistant agent should remain on 80～95 ℃.Because the component solubleness of this plating assistant agent is low, thereby temperature is low excessively causes helping the plating effect bad; Temperature Tai Gaoyi makes water evaporates fast, causes plating assistant agent concentration to increase, and causes waste.
Water-soluble fluxing agent provided by the invention has stronger activation to steel surface, thereby has improved the wetting capacity of aluminium liquid to steel surface, and the component of plating assistant agent does not all produce deleterious effect to the liquid of aluminizing, aluminized products.In addition, after plating piece helped plating to handle, fast drying can allow under higher temperature dry; The plating assistant agent component does not evaporate, and is not aging; Compare with existing water-soluble fluxing agent, price is lower.
Embodiment provided by the invention:
With carbon content 0.12%, thick 1 millimeter mild steel plate test specimen after abundant fat, pickling, washing, is immersed in respectively in the water-soluble fluxing agent of following proportioning composition.
Annotate: the concentration expressed in percentage by weight of HF is 40%
Flood and take out after 10～20 second time dryly, immerse again in 700 ℃ the molten aluminum liquid, take out behind the immersion plating appropriate time, all can obtain smooth smooth aluminium coated.
