て損なわれる。(Prior art) Horizontal electroplating equipment does not involve bending during the plating process, so there are no restrictions on the thickness or width of the steel strip that can be used, and it is also easier to wind than the commonly used dip plating method. Recently, many improvements have been made to the structure of the electrode, the holding plate, etc., as the pulling force is small and a small winding device can be used. Although horizontal electroplating equipment has these characteristics, when electroplating iron or iron alloys, the surface of the plated steel sheet changes from metallic luster to grayish brown, deteriorating the appearance of the plated plate. , there was a problem that diminished the product value. This problem is caused by Fe+++, which is generated by the reaction between oxygen in the air and Fe ++ in the electrolyte when air is entrained in the electrolyte circulating in the device, and the Fe +++ is generated by the reaction between oxygen in the air and Fe++ in the electrolyte. This is caused by the electrolyte that has been discharged and fallen, causing the liquid surface to ripple violently. Figure 1 shows the relationship between the Fe +++ concentration in the electrolyte and the appearance of the plated steel sheet. In other words, the appearance of the plated steel sheet is impaired by the infiltration of an excessive amount of Fe +++ .

This is an attempt to avoid the above problem. The gist of this is that an insoluble electrode is installed parallel to the upper and lower surfaces of a steel strip that passes above the liquid surface of the electrolyte storage tank and spouts electrolyte at intervals, and the lower end is placed above the electrolyte discharge side. This is a horizontal electroplating device with an inclined or curved electrolyte discharger that is immersed in the electrolyte in the tank.
