Abstract
The invention relates to ternary adjusting alloy specially used for galvanization and a manufacturing method thereof. The ternary adjusting alloy specially used for the galvanization mainly comprises three elements, namely Zn, Al and RE; the components of the ternary adjusting alloy account for the following total mass percent: 1 to 20 percent of Al, 0.1 to 5 percent of RE, and the balance of Zn; and by adopting the ternary adjusting alloy specially used for the galvanization, the purpose of reducing the coating thickness is achieved and the use rate of the Zn metal is improved. The invention can be widely applied to household electrical appliances, building materials and automobile industries.
Description
Technical field:
The present invention relates to a kind of ternary adjusting alloy specially used for galvanization and manufacture method thereof.
Background technology:
Because household electrical appliances, building materials, automobile fast development, to the demand fast rise of Galvanized Steel Strip or steel plate, zinc consumption heightens, and generally speaking, coating is two-sided will to reach 150 gram/m
2More than, but because zinc resource day by day reduces, under the prerequisite that does not reduce Zn coating anti-corrosion function, how saving zinc resource becomes when last important topic.For addressing this problem, the applicant also proposed relevant series application before this as introducing among the CN200610038386, think that at this content of Al wherein is in Al50%～60% the best in first to file, saving zinc resource that can be a large amount of, but because the too high levels of Al, the Al price is higher than the Zn price, and hot dip producer cost rises, therefore, there is certain deficiency in actual applications.
Summary of the invention:
At the problems of the prior art, the present invention has further done improvement, overcome original simple by improving Al content to replace the technology prejudice of Zn, a kind of Al-Zn-RE ternary adjusting alloy of zinc-plated special use newly is provided, not only reduced the content of Al, more realize to reduce the thickness of Zn coating, thereby when having improved the adjustment alloy property, saved zinc resource greatly.
Ternary adjusting alloy specially used for galvanization of the present invention, mainly elementary composition by Zn, Al, RE, each composition of wherein said ternary adjusting alloy accounts for total mass per-cent: Al:1～20%, RE:0.1～5%, Zn is a surplus, thereby wherein RE adds the purpose that the flowability that not only increases zinc liquid reaches the reduction thickness of coating, and RE adding further raising Zn corrosion resistance of coating, also reduce zinc pot slag growing amount simultaneously, improve Zn metal rate of utilization.
Also comprise trace additives in the wherein said ternary adjusting alloy, described trace additives is selected from one or more among Fe, Si, Mn, Pb, Sb, Sn, Cu, Ca, the Bi, and described trace additives total content is below 0.5%.
The concrete content of each composition of wherein said trace additives: Fe＜0.15%, Si＜0.10%, Mn＜0.1%, Pb＜0.1%, Sb＜0.1%, Sn＜0.1%, Cu＜0.1%, Ca＜0.1%, Bi＜0.1%.
In addition, the present invention also provides a kind of method of making ternary adjusting alloy, mass percent by described Zn, Al, RE element is got the raw materials ready, during earlier with smelting furnace pre-heating temperature elevation to 600～700 ℃, adding Al and RE adds with the Al-RE master alloy, when fusing is warming up to 795～805 ℃ again, add Zn, left standstill after stirring 10～35 minutes.
Before the step that adds Zn, also comprise the step of adding trace additives, described trace additives is selected from one or more among Fe, Si, Mn, Pb, Sb, Sn, Cu, Ca, the Bi, and described trace additives total content is below 0.5%.
Adopt the Al-Zn-RE ternary adjusting alloy of zinc-plated special use of the present invention, can make the coating attenuation, and then saved zinc resource greatly, and solidity to corrosion do not fall, end slag growing amount is few, easy to operate.
Embodiment:
Ternary adjusting alloy specially used for galvanization of the present invention, mainly elementary composition by Zn, Al, RE, each composition of wherein said ternary adjusting alloy accounts for total mass per-cent and is: Al:1～20%, RE:0.1～5%, Zn are surplus.Following table is listed to be some preferred embodiments of the invention, but the content of each composition of the present invention is not limited to listed numerical value in this table, for those skilled in that art, fully can be in table rationally summarizes and reasoning on the basis of listed numerical range.
Each forms the mass percentage content (%) that part accounts for gross weight
Also comprise trace additives in the wherein said as can be seen from the table ternary adjusting alloy, described trace additives is selected from one or more among Fe, Si, Mn, Pb, Sb, Sn, Cu, Ca, the Bi, and described trace additives total content is below 0.5%.
The concrete content of each composition of wherein said trace additives: Fe＜0.15%, Si＜0.10%, Mn＜0.1%, Pb＜0.1%, Sb＜0.1%, Sn＜0.1%, Cu＜0.1%, Ca＜0.1%, Bi＜0.1%.
A kind of method of making ternary adjusting alloy is got the raw materials ready by the mass percent of described Zn, Al, RE element, during earlier with smelting furnace pre-heating temperature elevation to 600～700 ℃, adding Al and RE adds with the Al-RE master alloy, when being warming up to 795～805 ℃ again, add Zn, left standstill after stirring 10～35 minutes.
After the step that adds Zn, also comprise the step of adding trace additives, described trace additives is selected from one or more among Fe, Si, Mn, Pb, Sb, Sn, Cu, Ca, the Bi, and described trace additives total content is below 0.5%.
Induction stirring is adopted in wherein said contactless stirring, and refining agent is a rare gas element, and refining finishes to check air content that can come out of the stove after gassiness is qualified pours into the pure ingot of 660 * 108 * 66mm.
Adopt the Al-Zn-RE ternary adjusting alloy of zinc-plated special use of the present invention, can make the coating attenuation, and then saved zinc resource greatly, and solidity to corrosion do not fall, end slag growing amount is few, easy to operate.
