Abstract
Hot-dip plating with aluminium rare earth alloy belongs to the steel surface coating resist technology.
The present invention is a kind of aluminum alloy hot-dip coating that contains rare earth of steel and metal products surface protection.Contain 0.05～1% rare earth in this coating, all the other are aluminium.This coating is iron and steel and the metal products spare that will clean up, and places KCl-NaCl-NaF-AlF
3In the Al rare earth alloy plating bath under the fused salt mixt protection,, obtain through aftertreatment again 670～690 ℃ of following immersion plating 2～10 seconds.This plating bath mainly is to utilize rare earth that aluminium liquid is had the effect of purification and crystal grain thinning and the solidity to corrosion and the sticking power that have strengthened aluminium, thereby has protected steel surface not to be corroded and increased work-ing life.
Description
Hot-dip plating with aluminium rare earth alloy belongs to the steel surface coating resist technology.
The present invention is a kind of aluminum alloy hot-dip coating that contains rare earth metal of steel and metal products surface protection.
Since steel wire, plate, pipe etc. are long-term all is to protect with zinc; but zinc coating at region following the line of the sea and industrial atmospheric corrosion than serious area; its corrosion resisting property is relatively poor; according to the extent of corrosion difference; the general use just need be changed in 2～5 years; this not only wastes steel but also need a large amount of construction costs, just more be difficult to estimation owing to change the social loss that causes because of power failure on the other hand, thereby people seeks just than zinc coating better protection coating.First part of patent of aluminizing appearred in the U.S. in 1893, at first began industrial production steel surface aluminized products in 1958 in the ACCO of U.S. company and Bethlehem company through the research of six more than ten years.For sticking power that increases aluminium and iron and the flowability that increases aluminium liquid, all in aluminium liquid, add 1～3% silicon usually, reduced the anti-corrosion capability of coating owing to the adding of silicon.
In order further to improve the corrosion resisting property of iron and steel coating, increase aluminium to the sticking power of steel surface with improve electric property, the present invention has studied the influence of adding rare earth in aluminium coat, evidence adds the solidity to corrosion that rare earth can improve coating, its solidity to corrosion has surpassed existing silicon-aluminum containing coating, rare earth can also suppress the generation of alloy layer and increase the sticking power of aluminium and iron, and its electric property is considerably beyond galvanizing line, and the line hepatitis consumption under the high frequency also reduces greatly.But this mainly is the reason of adding purification and crystal grain thinning in the aluminium liquid owing to rare earth to.
The objective of the invention is to increase the solidity to corrosion and the sticking power of hot-dip aluminizing.
Concrete enforcement is: in aluminium liquid, add 0.05～1% rare earth, under 670～690 ℃ at KCl-NaCl-NaF-AlF
3(equimolar KClNaCl is 50～70% to fused salt mixt; all the other are that molecular ratio is 1.0～2.0 sodium aluminum fluoride) protection is down; the plating piece that cleans up was stopped 2～10 seconds in containing the aluminium liquid of rare earth, handle after the taking-up, can evenly do not had the Al rare earth alloy coating of burr light.
The present invention studies have shown that: the corrosion resisting property of steel surface coating is that Al-RE＞pure Al＞Al-Si＞Zn(RE is a norium in proper order) hot dip aluminum plating rare earth alloy technology schema sees accompanying drawing.
Claims (5)
1, a kind of new steel and metal products is hot-dip coated, it is characterized in that coating also is added with rare earth except that aluminium.
2, steel as claimed in claim 1 and metal products coating is characterized in that the rare earth that is added is a mishmetal, and its add-on is 0.05～1%.
3, hot-dip coated as claim 1,2 described steel and metal products, the main technologic parameters during immersion plating is: 670～690 ℃ of bath temperatures, the immersion plating time is 2～10 seconds.
4, steel as claimed in claim 1 and metal products are hot-dip coated, and KCl-NaCl-NaF-AlF will be used in the plating bath surface during its immersion plating
3Fused salt mixt is done protection.
5, hot-dip coated as claim 1,4 described steel and metal products, the proportioning (below be weight %) of protection fused salt is 50～70% for equimolar KCl.NaCl during its immersion plating, and all the other are that molecular ratio is 1.0～2.0 sodium aluminum fluoride.
