CONSTITUTION:A housing 1 which is halvely hermetically sealed in apertures 3, 4 for introducing and leading out the metallic strip 2 by sealing rolls 5 is internally maintained in an inert gas kept at the pressure higher by >=0.05mm with the water column pressure than the outside atm. pressure of the housing and at -10 deg.C lower than the dew point. While the metallic strip 2 from the aperture 3 for introducing is repetitively moved in a vertical direction by plural energizing rolls 8 arranged in the upper part within the housing 7 and plural sink rolls 9 arranged in the bottom, the metallic strip 2 is guided to the aperture for leading out. A plating liquid 12 which is kept at 80 to 150 deg.C by being passed through a heat exchanger 15 from an external liquid storage tank 13 is ejected from above between the metallic strip 2 moving with both of the energizing rolls 8 and the sink rolls 9 and anode plates 10 parted from and disposed along the metallic strip 2 from nozzles 11 and is electrolyzed while the metallic strip 2 and the anode plates 10 are held energized.

2. Description of the Related Art When an organic nitrogen-onium halide such as imidazolium halide or pyridinium halide is mixed with one or more kinds of metal halides, a low-temperature molten salt plating solution which becomes liquid even at room temperature is obtained. It is known that the resulting mixed metal halide metals or their alloys can be electroplated. The characteristic of this plating solution is that if a metal that is difficult to electrodeposit in an aqueous solution plating solution is used for the mixed metal halide, for example, a halide such as Al, Ti, W, or Mo is used, the metal or alloy will have high purity, and , It can safely electroplate at low temperature.

When a metal strip is electroplated with this plating solution, the plating solution is prepared by mixing a mono-, di- and / or trialkyl-substituted organic nitrogen onium halide and a metal halide. However, when the plating operation is performed in the atmosphere, the ions are oxidized by oxygen in the atmosphere regardless of the type of organic nitrogen-onium halide, and the plating solution deteriorates due to fluctuations in the composition of the plating solution. It was performed under an inert atmosphere such as argon gas. In addition, since the plating solution has a significantly higher specific gravity and viscosity and a lower electrical conductivity than the aqueous solution plating solution,
When performing high-speed plating, the current density was increased by taking measures such as vigorously stirring the plating solution or adding an organic solvent to reduce the viscosity.

However, even if such a measure is taken, there is a limit in increasing the current density in the ordinary metal strip electroplating method of electroplating the upper and lower surfaces while moving the metal strip in the horizontal direction. . Therefore, a method is proposed in which the width direction is made vertical so that the metal strip does not hang down, the gap between the metal strip and the anode is narrowed, and the plating solution is jetted from below the plating tank to enable high-speed plating even with the same current density.

No. 04794).

However, in order to prevent the metal strip from passing through the plating tank while keeping the metal strip vertical, in order to avoid this, a horizontal metal strip is placed inside the plating tank. If the surface is turned by 90 degrees, the plating tank must be lengthened. In addition, there is a problem that the plating appearance is gradually discolored when the plating operation is continued for a long time by simply making the atmosphere of the plating solution inert.

The present inventors have completed the present invention as a result of intensive studies to solve such a problem. That is, the present invention provides an electroplating method capable of performing plating at a high current density, and in which the plating does not discolor even when the plating operation is continued for a long time, and the openings for introducing and leading out the metal strips are provided. -Ruro-
The inside of the housing, which is semi-sealed with a vacuum, is maintained in an inert atmosphere with a dew point of -10 ° C or less, which is 0.05 mm or more higher than the atmospheric pressure of the housing at a water column pressure, and the metal strip from the introduction opening is placed in the upper part of the housing. Multiple energized rolls arranged

Pass the heat exchanger from the external storage tank from the upper side between the separated anode plates and 80-150 ℃
It is characterized in that the plating solution maintained at is ejected from a nozzle to electrolyze the metal strip and the anode plate while energizing them.

According to the present invention, the metal strip is repeatedly moved up and down by the energizing roll and the synchro while the plating solution is jetted by the nozzle between the up and down metal strip and the anode plate. Therefore, the jetted plating solution does not need to push away the surrounding plating solution, and gravity acts on the plating solution. Therefore, even if the viscosity is large,
The flow velocity can be increased, and the flow velocity does not decrease even on the side of the synchro separated from the nozzle.

Since the internal pressure inside the housing is higher than the external pressure by 0.05 mm or more in water column pressure, it is possible to prevent air from entering the housing from the outside. If the internal pressure is lower than 0.05 mm with respect to the external atmospheric pressure, air will be entrained from the opening, degrading the plating solution. The internal pressure is preferably such that the atmospheric gas discharge rate from the opening is 1.0 m / sec or more.

The dew point of the inert atmosphere in the housing is controlled because the plating solution reacts with water and deteriorates while generating harmful hydrogen halide gas. That is, the inventors of the present invention, the deterioration of the plating solution when the plating operation is continued for a long time is caused by the water contained in the inert atmosphere, and the plating solution is jetted by a nozzle between the metal strip and the anode plate. In the case of the present invention in which the material flows down, it has been found that this must be strictly controlled as follows.

In the case of a usual plating method in which plating is carried out by passing through the plating bath, the plating solution which comes into contact with the atmosphere in the housing is only the solution present on the bath surface. Since it comes into contact with the plate each time it flows down, the whole plating solution comes into contact with the atmosphere in the housing little by little. Moreover, since the contact is made while dropping in the atmosphere, the total contact area per unit time becomes large. Therefore, even if the water content in the atmosphere is the same as in the case of the conventional ordinary plating method, it was found that the plating bath deteriorates when the plating is continued for a long time, and the atmosphere dew point is set to -5 ° C. ~ 0 ° C to -10
It was necessary to keep the temperature below ℃, preferably below -15 ℃.

The plating solution jetted between the metal strip and the anode plate has a liquid temperature of 80 to 80% in order to ensure a uniform liquid flow without liquid breakage by lowering the viscosity and to increase the electrical conductivity. Bring to 150 ° C. Even if the liquid temperature is 80 ° C., the viscosity is about 5 times as high as that of the aqueous plating solution, but the flow rate on the synchro side can be 1.0 m / sec or more. Further, when the liquid temperature is set to 80 ° C. or higher, the electric conductivity becomes remarkably high as shown in FIG. However, if the temperature is higher than 150 ° C., the metal halide in the plating solution is easily sublimated, and the composition of the plating solution varies, which is not preferable.

Moreover, since plating is not a method of immersing in a plating bath, the sealing is easier than the case of plating by immersing in a plating bath in a vertical state. Moreover, since the plating is a vertical type, the plating apparatus can be downsized. Furthermore, the flow rate of the plating solution can be made higher than the stirring of the plating bath,
