- Reference numeral 2 denotes a shield, which is disposed between the molten metal drawing members 1 and 1 disposed opposite to the steel strip S on the copper strip surface extension, close to the end of the steel strip S.
- “On copper strip surface extension” means on a line parallel to the width direction of the steel strip.
- the “shielding body” is a member that shields the plating solution, and suppresses the flow of the plating solution from both ends of the copper strip toward the center of the steel strip.
- FIGS. 2 (a) and 2 (b) are diagrams for explaining the operation of the molten metal squeezing member and the shield of the apparatus of the present invention.
- FIG. FIG. 2B is a top view showing the flow of the molten metal at the end of the steel strip in the region sandwiched by the metal squeezing member.
- FIG. 2 (b) is the region sandwiched by the molten metal squeezing member when the molten metal squeezing member and the shield 2 are provided It is a top view which shows the flow of the molten metal in the copper band edge part in.
- a molten metal flow 1 1 from the end of the steel strip toward the center of the steel strip is generated as shown in Fig. 2 (a).
- the drawing effect of the molten metal drawing member 1 is weakened or disappears at both ends of the steel strip.
- the shield 2 when the shield 2 is disposed between the molten metal drawing members 1 and 1 disposed opposite the copper strip on the copper strip surface extension, the center of the steel strip from the end of the copper strip Since the flow of the molten metal toward the part can be cut off, the excessive molten metal squeezing effect by the molten metal squeezing member 1 can be expressed uniformly over the entire width of the steel strip.
- the amount of splash generated can be adjusted with the gas wiping nozzle after the amount of excess molten metal attached to the steel strip has been reduced over the entire width of the steel strip by the molten metal drawing member and shield. Can be greatly reduced.
- the molten metal squeezing effect can be exhibited even if the plate passing speed is significantly increased, the amount of splashing can be greatly reduced, so that a molten metal-plated steel strip having no surface defects can be produced with high productivity. It is possible to manufacture while maintaining the above. It is desirable that the steel strip side end surface of the shield 2 be orthogonal to the steel strip surface as shown in Fig. 2 (b).
- the distance between the end of the steel strip and the end surface of the shield 2 on the steel strip side should be 5 mm or less. The smaller the distance, the better. Furthermore, the most suitable condition is that the end of the copper strip and the end of the shield 2 are in contact with each other in a state where no pressing force is applied to the steel strip.
- the gap between the molten metal squeezing member 1 and the shield 2 is preferably 3 mm or less, and the smaller the gap, the better.

The drawing performance of member 1 can be further improved. If the cross-sectional shape of the molten metal restricting member 1 is such a shape, even if a flow accompanying the progress of the steel strip S (associated flow) 1 1 is generated, the fluid is easy to flow in the direction of low resistance.
- the flow 1 3 branches at the lower end of the molten metal restricting member 1 and functions to prevent the growth of the accompanying flow 1 1. Furthermore, since the flow 1 3 is directed away from the steel strip S, the flow 1 3 is opposed to the flow 1 2 toward the copper strip S above the molten metal drawing member 1, and the effect of reducing the velocity of the flow 1 2 is also achieved.
