用いられる。Hereinafter, the present invention will be described by way of examples with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the device of the present invention. In the figure, reference numeral 1 denotes a plating material such as a wire, a strip, a tape or a plate, which is pulled up vertically from the plating bath 2. A plate-shaped heat insulating material 3 is arranged on the surface of the plating bath near the pulled-up portion of the plated material 1. The heat insulating material 3 heat-insulates and protects the surface of the plating bath 2 except for an exit portion of the plating material 1 from the bath, and has a hole 5 through which the plating material 1 passes. The hole 5 has an inner diameter capable of sufficiently accommodating the raised portion 6 due to the surface tension of the plated material 1 and the molten metal around it. As the heat insulating material 3, for example, a heat insulating material such as asbestos, ceramics, or ceramic fiber is used.

れる形状のものであれば良い。A cooling hood 4 is put on the upper surface of the heat insulating material 3. The cooling hood 4 guides the cooling gas 7 from the lower part to the upper part along the periphery of the plated material 1.
And a gas outlet 9 for discharging the gas 7 along the plated material 1. The shape of the cooling hood 4 is shown as a wide stepped tubular shape at the bottom in the figure, but the present invention is not limited to this, and the gas 7 introduced at the bottom is uniformly distributed around the plated material 1. Any shape may be used as long as it has a sufficient width and the gas 7 is guided upward from below the periphery of the plated material 1.

が最適である。In order to carry out plating using such an apparatus of the present invention, the plating material 1 is passed through this apparatus and the cooling gas 7 is supplied from the gas inlet 8.
To introduce. As the cooling gas, for example, N 2 , Ar, air or the like or a mixture thereof can be applied, and in particular, cooling in a state of a low temperature gas vaporized from a liquid state (eg, vaporized N 2 gas etc.) is optimal.

昇せず、めっき材の冷却能が強化される。In this way, since the molten metal surface other than the exit portion from the bath of the plating material and the cooling gas 7 are separated by the heat insulating material 3, the temperature of the molten metal can be kept stable and at the same time the cooling gas 7 introduced The temperature does not rise until it reaches the outlet portion, and the cooling ability of the plated material is enhanced.

る。Further, the cooling gas 7 introduced into the lower portion of the cooling hood 4 has a lower specific gravity due to thermal expansion, and the gas 7 having an increased temperature is guided upward, and is guided along the plated material 1 from the upper gas discharge port 9. Since the gas is discharged, a lower temperature gas exists below the rising portion of the plating material, and the plating material is rapidly cooled in the high temperature state pulled up from the surface of the plating bath to enhance cooling.
この急冷により、めっき材１は付着するめっき金属が厚
くてもたれ下がりが防止されるので、表面外観の良好な
めっき材が得られる。By this rapid cooling, the plated material 1 is prevented from sagging even if the plated metal adhered thereto is thick, so that a plated material having a good surface appearance can be obtained.
（発明の効果） 上述のように構成された本発明の連続溶融めっき方法は
次のような効果を有する。(Effects of the Invention) The continuous hot dip plating method of the present invention configured as described above has the following effects.

化され、急冷が可能となる。(A) Since the surface of the plating bath in the vicinity of the pulling part of the plated material is covered with a heat insulating material and the cooling hood is installed above it, when cooling gas is introduced from the lower part of the cooling hood,
Since the molten metal surface other than the throttled part and the cooling gas are separated by the heat insulating material, the temperature of the molten metal is kept stable and the temperature of the introduced cooling gas reaches the outlet part from the bath of the plating material. The cooling capacity of the plated material is strengthened and rapid cooling is possible.
