た。(Background technology) Zinc plating has traditionally been used mainly for corrosion resistance, and in recent years, zinc plating has been used mainly for the purpose of increasing power transmission capacity.
Galvanized iron wire came to be used as the steel core for hot steel core aluminum stranded wire (referred to as V, bottom, side 1 heat AC3R), and heat resistance was required in addition to corrosion resistance. .

性である耐熱性を劣化する問題点があった。However, when hot-dipping the iron-based wire by continuously dipping it in a Zn-Aj' (alloy bath), the wire is coated with NH4Cl-ZnCl.
After performing flux treatment such as 2, it is immersed in a hot-dip plating bath, but at the immersion port of this plating bath, AβC 3 is generated due to the reaction between Ae in the Zn-A4 alloy bath and the flux, and therefore As the concentration of Ae decreases, Fe-Z is generated at the interface during hot-dip plating or when the temperature rises during use.
There was a problem that the formation of the n-alloy layer could not be prevented, and the most important characteristic, heat resistance, deteriorated.

湯の粘性か高くなり、めっきの外観不良か著しくなる。According to the present invention, the use of a Zn alloy bath containing 2 to 14% of A40 allows the VCFe-A (J alloy layer to be formed preferentially at the interface between the iron system and the Zn alloy during plating or when the temperature is increased during use. This is to suppress the growth of the Fe-Zn alloy layer, which causes peeling of the plating. If the amount of p, Il is less than 0296, it is not effective in suppressing the alloy layer, and if the amount of Ae exceeds 14%, the effect of suppressing the alloy layer is Not only does this saturate, but the viscosity of the molten 7.n-J alloy increases, and the appearance of the plating becomes noticeably poor.

The Zn-17 (1 alloy) is immersed in the alloy plating bath 2 by the sinker roll 3 and pulled up through the squeezing device 4 to form the Zn-17 (1 alloy plating material 5).
, 2 to 14%, and the remainder is Zn and unavoidable impurities. In this state, the flux reacts with Aβ in the bath at the immersion port of plating bath 2, producing a large amount of AlIcβ3, and the Aβ concentration at the immersion port decreases to less than 0.2%, suppressing the alloy layer at the interface described above. It becomes ineffective.

儂度全めっき浴より若干高くすることが望捷しい。Therefore, in the present invention, the Zn-A1 alloy wire 6 is continuously supplied to the immersion port of the plating bath 2 from the supply device 7 and melted. The Zn-A4 alloy wire 6 has the same composition range as the plating bath 2, and in consideration of the above-mentioned loss of A, it is desirable to make the A content slightly higher than that of the entire plating bath.

る。The AI concentration, wire diameter, and supply speed of the Zn-Ap alloy wire 6 to be supplied are appropriately determined depending on the size of the plating bath actually supplied, the dimensions, number, and plating speed of the iron-based long wires to be plated. It is easy to select and change according to the operating format.

可能である。When the Zn-A1 alloy wire 6 is supplied in this way, it is easily dissolved in the plating bath, and the local temperature at the immersion port is 0.2 to 0.2 degrees.
It is possible to obtain a Zn-A4 alloy plated material 5 which can be controlled to a desired a value in the range of 1496 and has uniform high heat resistance over the entire length. Is there any way to constantly supply Δβ while keeping the temperature high?At a normal plating bath 2 temperature of around 450°C, Aβ

Since the Zn-41 alloy wire 6 is supplied with an Ala degree that is sufficiently melted at the front and rear ends, there is an advantage that the components can be easily retained by the supplied Zn-Aβ alloy wire.

βCβ3 crystallizes, the Aβ concentration directly below the immersion port decreases to 0.15%, and an average of 26 μ7 at the interface between the iron system and the Zn alloy.
A Fe-Zn compound layer with a thickness of 71 mm was produced.

At this time, the alloy wire 6 was immersed in the plating bath 2 and melted at the same time.
