従来よシ溶融塩を浴液としたアルミニウム電解メッキは
鋼材へのメッキ方法として知られているがほとんど実用
化されていない。Conventionally, aluminum electrolytic plating using molten salt as a bath liquid has been known as a method of plating steel materials, but it has hardly been put into practical use.
その理由の１つとして鋼材の表面を活性化する適当な手
段が開発されていなかったことが挙げられるが、この問

５日付でなした特許出願明細書参照〕。One of the reasons for this is that a suitable means for activating the surface of steel materials had not been developed, but this problem was solved by the method previously proposed by the applicant, namely:
The problem was solved by a molten salt electrolytic plating method for steel materials, which is characterized by subjecting the steel material to an anodic dissolution treatment to activate the surface of the steel material prior to molten salt electrolytic plating of the steel material [1. Method for molten salt electrolytic plating of steel materials] See the specification of the patent application filed on December 5, 1986 under the heading:

させるという問題があった。However, in the above proposed method, the iron eluted into the molten salt by anodic dissolution of the steel material becomes iron ions and accumulates in the bath solution, and the bath solution containing these iron ions adheres to the steel material and enters the plating bath. When iron ions are introduced into the molten salt bath solution, the iron ions in the plating bath solution increase, and when the iron ions in the plating bath solution increase, iron gets mixed into the plating film on steel materials, causing the problem of deteriorating the quality of the plating film. there were.

On the same date as the present invention, under the title molten salt electrolytic plating method, molten salt electrolytic plating of steel materials is carried out in combination with a pretreatment operation in which the steel material is anodically melted in a molten salt bath and its surface is activated. We proposed a molten salt electrolytic plating method in which iron ions generated by anodic melting of steel are reduced by adding and mixing a metal with a higher ionization tendency than iron and precipitated as metallic iron. .

面を傷つけるという問題点を有していた。However, in the above method, a metal with a higher ionization tendency than iron is added to the anode solution bath for steel materials, so that iron precipitated in the bath solution is present. Not only does this cause deterioration of the bath liquid, but also there is a problem in that when steel materials (for example, copper strips) are conveyed, iron gets caught between the feed rollers and the like and damages the surface of the steel materials.

。That is, in the present invention, as described above, iron ions generated in the bath liquid of the pretreatment tank are led to the iron ion removal tank through an external route, and there, they are brought into contact with metal particles that have a higher tendency to ionize than iron to precipitate iron. This prevents the bath liquid in the pretreatment tank from being degraded by iron and prevents damage to steel materials.
