本発明は、長尺材の周りに金属又は合金の溶融めっきを
連続的に施す方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of continuously applying hot-dip plating of metal or alloy around a long material.
（背景技術）
従来、線、条、テープ、板等の長尺材をフラックスを用

カーロールである。(Background Art) Conventionally, in order to continuously hot-dip plate long materials such as wires, strips, tapes, and plates using flux, a method such as the one shown in FIG. 2 has been used. As shown in the figure, after being immersed in a plating bath I2, excess plating material was squeezed out using a diaphragm I4 made of carbon, dice, etc., and plating was performed. 13 is a sinker roll.
この場合、めっき未着を生じることがしばしばあった。In this case, non-plating often occurred.
例えばＡＱを含むＺｎ合金めっきではＡＱＯ，２％以上
でめっき未着を生じ易かった。For example, in Zn alloy plating containing AQ, non-plating tends to occur when the AQO is 2% or more.
この未着対策としてフラックスの組成が種々検討されて
いたが、フラックスがめつき浴と反応後もしばしば表面
に残り、めっき浴と被めっき材表面との反応を妨げるた
め、めっきの未着の原因となったり、又めっき後表面の
変色問題を生じる欠点があった。Various flux compositions have been investigated as a countermeasure for this non-adhesion, but flux often remains on the surface even after reacting with the plating bath and prevents the reaction between the plating bath and the surface of the plated material, which may be the cause of the non-adhesion of the plating. There was also a problem of discoloration of the surface after plating.
例えば上述のＡｌ０．２％以上を含存するＺｎ−ＡＱ合
金めっきは耐食性が良好であり、又めっき時にＺｎの合
金層を生成しないため、特に耐熱性が良好であり、開発

スを生じ、線表面に残留するため、めっきの未着を生じ
昌り、又めっき後一方、酸化還元を利用するゼンジマー
法もこの種のめっきに利用されていたが、酸化還元に高
温処理を必要とし、高温を経るため、強度が低くなる欠
点があった。For example, the above-mentioned Zn-AQ alloy plating containing 0.2% or more of Al has good corrosion resistance and does not produce a Zn alloy layer during plating, so it has particularly good heat resistance, and its development has been desired. , a high concentration of AQ dross is produced on the surface of the plating bath, and this AQ and flux react to produce AUCQa gas, which remains on the wire surface, resulting in non-adhesion of the plating and, on the other hand, oxidation-reduction after plating. The Sendzimer method has also been used for this type of plating, but it requires high-temperature treatment for oxidation-reduction and has the drawback of low strength due to the high temperature.

することができる。５はシンカーロールである。Reference numeral 2 denotes a plating tank, in which a Pb bath 3 is accommodated in the lower part, and a Zn-AQ alloy plating bath 4, for example, is floated at the outlet thereof. The long material 1 coated with flux is first immersed in a Pb bath 3 and subjected to a contact reaction, thereby making the surface clean and active. The long material 1 with a clean and active surface is then immersed in the Zn-Af1 alloy plating bath 4, the material and the plating bath react, and the material is squeezed and pulled up by the aperture 6, thereby causing non-plating. Therefore, a uniform plating layer can be deposited. 5 is a sinker roll.

It is preferable that 0.2 to 60% be impregnated, with the remainder consisting of Zn and unavoidable impurities. If AQ O, 2% is not grooved, the main purpose of improving heat resistance and corrosion resistance cannot be expected, and if AQ exceeds 1i0%, the effect of improving heat resistance will be saturated, and the viscosity of the molten alloy will increase, making it difficult to melt. Appearance defects during plating become significant.
