Description of the Related Art Conventionally, an electrolytic treatment apparatus for a steel plate is connected to the above steel plate by immersing a steel plate to be electroplated or electrolytically polished from above into a large electrolytic solution tank containing a large amount of electrolytic solution. By passing an electric current between one electrode and the other electrode immersed in the electrolytic solution, a desired metal in the electrolytic solution is deposited on the surface of the steel sheet and electroplated on the surface of the steel sheet, or the steel sheet. There is known an electrolytic solution bath method in which a metal on the surface is melted and the surface of the steel sheet is electropolished.

解液浴方式にあっては、鋼板を浸漬する電解液槽が大規

要となり、それに伴って該電解液中の電流が低電流密度
となって電解処理の能率が低く、また、かなり大きな電
極を必要とするという問題がある。However, in the above electrolytic solution bath method, since the electrolytic solution tank in which the steel sheet is immersed is large-scale, a large amount of electrolytic solution is required to be stored in the electrolytic solution tank. Along with this, there is a problem that the current in the electrolytic solution becomes a low current density, the efficiency of electrolytic treatment is low, and a considerably large electrode is required.

う問題もある。Further, unless the optimum electrolytic solution temperature is secured as a condition for carrying out the electrolytic treatment, the limiting current density is lowered and pinholes are generated. Therefore, it is necessary to control the temperature of the electrolytic solution. When a large amount of electrolytic solution is used as described above, there is also a problem that it is necessary to increase the capacity of a temperature control device such as a heater for maintaining the large amount of electrolytic solution at a constant temperature.

いという問題がある。Further, it is known that if the electrolytic solution is not washed immediately after washing with water, an unnecessary electrolytic solution remains on the surface of the steel sheet after the processing, resulting in deterioration of the quality of the surface of the steel sheet after the electrolytic processing. In the electrolytic bath method, there is also a problem that the washing efficiency is large because a large-scale washing facility is required. Also, in the latter electrode pad method, compared with the electrolytic bath method, the viscosity of the electrolytic solution is not always applied uniformly to the steel plate surface due to the viscosity of the paste, Since it is necessary to slide and perform electrolytic treatment,
There is a problem that the electrolytic treatment efficiency is poor and it is difficult to slide on the surface of the steel sheet to be treated while maintaining a uniform current density.

The object is an electrolytic treatment method and an apparatus therefor.

Is applied.

な底板を使用するとよい。At this time, if the electrolytic solution ejected from both nozzles and the water are mixed, the concentration of the electrolytic solution recovered after the electrolytic treatment becomes thin, and the concentration control of the electrolytic solution becomes difficult. For example, it is necessary to return the electrolytic solution stock solution to a predetermined concentration by introducing an electrolytic solution raw material and performing an evaporation work of water by an evaporator or the like. In order to prevent this and separate and recover the electrolytic solution and water after the electrolytic treatment, it is preferable to use the bottom plate as described in claim 4.

された電解液へ混入することが大幅に減少する。The bottom plate is lifted up in succession along the movement of the trolley at the portions facing vertically between the electrolyte solution nozzle and the water washing nozzle, and the bottom plate is bordered by the lifted position. The upper surface forms a slope that goes in the opposite direction to the traveling direction of the carriage. Therefore, the electrolytic solution falling in the traveling direction of the carriage flows forward along the slope in the traveling direction, and the treated water falling in the opposite direction flows backward along the slope in the opposite direction, so that the electrolytic solution and the water are separated. It is possible to significantly reduce the amount of the cleaning water that has been collected and mixed with the electrolytic solution used for the electrolytic treatment.

ために鋼板端部から直下に流れ落ちる。The separated electrolytic solution and water after the treatment may be separated and recovered as described in claim 5. In this case, as shown in FIG. 10, since the electrolytic solution is injected in the longitudinal direction of the steel sheet, the electrolytic solution flows along the longitudinal direction of the steel sheet, most of it flows down from the front end portion in the longitudinal direction, and only a small amount of the steel sheet. It runs down from the widthwise end. A small amount of the electrolytic solution flowing down from the widthwise end flows down immediately below the steel plate end because the flow velocity in the widthwise direction of the steel plate is small.

る。On the other hand, the water for cleaning has a predetermined flow velocity in the width direction of the steel plate at the ends in the width direction of the steel plate because the water is sprayed with its axis oriented in the direction inclined from the longitudinal direction of the steel plate in the width direction. As it flows down, a parabola is drawn in the width direction from the widthwise end of the steel plate and drops downward at a predetermined distance in the widthwise direction from the widthwise end of the steel plate. By disposing the water receiving tank at that position, most of the water after cleaning is collected in the water receiving tank. Since this water receiving tank is separated from the end of the steel sheet in the width direction by a predetermined distance, the electrolytic solution hardly falls. As a result, the water is collected in the water receiving tank, and separated into a tank separately prepared for the electrolytic solution to be collected.

The electrolytic solution supplied between the other electrode and the steel plate surface is suppressed from flowing down from the steel plate width direction, and the filling property of the electrolytic solution located between the other electrode and the steel plate surface is increased to improve the electrical conductivity. The quality of the electrolytically treated steel plate surface is improved. In addition,
The plating thickness and polishing thickness etc. formed by electrolytic treatment are
It is controlled by the traveling speed of the carriage and the current density.

制御に必要な温度制御装置の容量も小さくて済む。The substantial amount of electrolytic solution required for electrolytic treatment, that is, the amount of liquid required for temperature control, is the amount of liquid filled between the other electrode and the surface of the steel sheet, and the amount of electrolytic solution in the electrolytic solution nozzle. Only a small amount of liquid in the pipe of the supply device to be supplied is required, and the capacity of the temperature control device necessary for controlling the liquid temperature can be small.
