ので生産性は著しく低下する。In addition, in conventional hot-dip plating equipment, the zinc roll used to guide the steel plate to be processed is immersed in a high-temperature hot-dip plating bath, so even if it is made of heat-resistant and corrosion-resistant material, it is severely corroded and must be replaced frequently. If this zinc roll is replaced, the line must be stopped, resulting in a significant drop in productivity.

The plating bath is constantly supplied, and the plating bath flows without contacting the surface of the steel plate to be processed as it passes through, and the plating bath is dropped downward from both outer sides of the steel plate and installed below. The purpose is to supply the plating bath from the main bath to the auxiliary bath above.
本発明に係る溶融メッキ方法を図面に示す例により詳細
に説明する。The hot-dip plating method according to the present invention will be explained in detail with reference to an example shown in the drawings.

のである。In the hot-dip plating method according to the present invention, an auxiliary bathtub 2.2' is provided which is divided into two by a deflector roll 8 with a gap through which the vertically arranged steel plates 5 to be treated can pass. An electromagnet 4.4 is buried in '.
Due to the force of the magnetic field of this electromagnet 4, the plating bath 3.3, which is constantly supplied to the auxiliary bath 2.2', is held during plating work and is prevented from coming into contact with the surface of the steel plate 5 to be processed as it passes through. The plating bath flows, falls downward from both outer sides of the steel plate to be treated, and enters the main bath 1 installed below,
The plating bath 3 in the main bath 1 is pumped into the auxiliary bath 2 through a pipe 10 by a pump 9 (metal pump, electromagnetic pump, etc.).
By supplying the steel plate 5 to the auxiliary bath 2',
．． When it passes through 2', it is taken out as a steel plate 5'.

助浴槽２．２′の間隙を通過する。That is, at a predetermined temperature and atmosphere, the steel plate 5 to be treated is vertically raised by the deflector roll 9 and passes through the gap between the two auxiliary baths 2.2'.
この時、補助浴槽２．２′には主浴槽１がらポンプ９に
よりパイプ１０からメッキ浴３が常時供給されている。At this time, the plating bath 3 is constantly supplied to the auxiliary bathtub 2.2' from the main bathtub 1 through a pipe 10 by a pump 9.

槽２．２′に供給される。Since the electromagnet 4 is buried in the auxiliary bath 2.2', the plating bath 3.3 is connected to the arrow 1 shown in FIG.
The auxiliary bathtub 2 is
．． 2', and the plating bath flows in an arc shape as shown by arrow 13 while contacting the surface of the steel plate 5 to be treated, during which time the steel plate 5 to be treated is plated and becomes a plated steel plate 5'. The plating bath that has been taken out and flowed down on the surface of the steel plate 5 to be treated and the plating bath overflowing from the auxiliary bath 2.2' enters the main bath 1 and is again supplied to the auxiliary bath 2.2' by the pump 9. .
以上の説明は被処理鋼板５の両面にメッキを施す場合で
あるか、次に被処理鋼板５の何れかの片面にメッキする
場合について説明する。The above description will be made regarding the case where both sides of the steel plate 5 to be treated are plated, or the case where either one side of the steel plate 5 to be treated is plated.

メッキが行なえるのである。In FIG. 1, the supply of plating bath to the auxiliary bath 2 (or 2') on the opposite side where the steel plate 5 to be plated is to be plated is stopped, and the same operation as described above for applying double-sided plating is performed. It is. In this case, since there is no plating bath on one side of the steel plate 5 to be treated, it will not be plated, and furthermore, the force of the magnetic field of the electromagnet 4 as shown in FIG. 2), the plating bath flows in the direction of the arrow 13, so the plating bath does not go around to the non-plated surface. Therefore, single-sided plating can be easily performed on any one side of the steel plate 5 to be treated by simply stopping the supply of the plating bath to any one of the auxiliary bathtubs 2 (2').
