Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は電気ターンめっき鋼板の製造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method of manufacturing an electro-turn plated steel sheet.
電気めっき法により製造されるターンめっき鋼板（Ｐｂ

融めっき製品に較べ外観が劣るという難点がある。Turn-plated steel sheet (Pb
The plated surface of the -5N plated steel sheet is matte and has a disadvantage in that its appearance is inferior to that of hot-dip plated products.
また、Ｐｂ−５ｎ合金めっき皮膜は極めて軟らかいため
にすり傷が付きやすく、しかもこのように傷が付くと、
その偏部は光沢を有するため非常に目立ちやすく、外観
を損なう。このようなすり傷は製造段階はもちろんのこ
と、加工段階でも発生し、めっき鋼板の商品価値を著し
く低下させる。In addition, since the Pb-5n alloy plating film is extremely soft, it is easily scratched, and if it is scratched like this,
Since the uneven portion is shiny, it is very noticeable and spoils the appearance. Such scratches occur not only during the manufacturing stage but also during the processing stage, and significantly reduce the commercial value of the plated steel sheet.
本発明はこのような問題に鑑みなされたもので、光沢を

を製造することができる方法を提供しようとするもので
ある。The present invention has been made in view of these problems, and it is an object of the present invention to provide a method for producing an electrically turned plated steel sheet that is glossy and has excellent abrasion resistance.
このため本発明は、電気めっきプロセスにより鋼板にタ

パス圧延を施すことをその特徴とする。For this reason, the present invention is characterized in that after a steel plate is turn plated by an electroplating process, the plated steel plate is subjected to skin pass rolling with light reduction.
以下本発明の詳細な説明する。The present invention will be explained in detail below.
第１図は本発明の実施状況の一例を示すもので、１はタ

ン下流側に設けられるスキンパス圧延機である。FIG. 1 shows an example of the state of implementation of the present invention, where 1 is turn plating equipment, 2 is a steel plate, and 3 is a skin pass rolling mill provided downstream of the plating equipment.
めっき設ｆ１１でターンめっきを施された鋼板２は、ス
キンパス圧延機３で軽圧下圧延が施される。The steel plate 2 subjected to turn plating in the plating facility f11 is subjected to light reduction rolling in the skin pass rolling mill 3.
この圧延では、極めて軟らかいＰｂ−５ｎ合金層をつぶ
す程度の圧下がなされる。この軽圧下圧延の圧下率は０
．５〜１％程度が好ましい。In this rolling, a reduction is made to the extent that the extremely soft Pb-5n alloy layer is crushed. The reduction rate of this light reduction rolling is 0
．． It is preferably about 5 to 1%.
このような軽圧下のスキンパス圧延の実施により、めっ

り傷も目立ちにくくなり、耐すり偏性も向上する。By carrying out skin pass rolling under such light reduction, the surface of the plating film is smoothed, resulting in a very glossy plating surface. Furthermore, since gloss is imparted in this manner, scratches become less noticeable and the abrasion resistance is improved.
なお、圧延に使用するロールはブライト仕上げ、ダル仕
上げのいずれでも良い。Note that the rolls used for rolling may have either a bright finish or a dull finish.
また、ターンめっき鋼板は、めっき表面をブラシロール

ブラッシングを行うようにしてもよい。Furthermore, since glossiness can be imparted to a turn-plated steel sheet by lightly polishing the plated surface with a brush roll, the above-mentioned light brushing may be performed prior to skin pass rolling with light reduction of the present invention.
第１図に示すように、電気ターンめっき設備１の下流側

キンパス圧延を実施した。その具体的条件は以下の通り
である。As shown in FIG. 1, a skin pass rolling mill 3 was disposed downstream of the electric turn plating equipment 1, and light reduction skin pass rolling was performed on the plated steel sheet. The specific conditions are as follows.
鋼板送り速度：２０−２０−３Ｏ
使用ロール：ブライト仕上げ
圧延荷重： ２００−３００Ｔｏｎ （ＩＩＡ圧２−３
Ｔｏｎ／ａｎ）圧延率：０．５〜１％
このようにしてスキンパス圧延を実施しためっき鋼板と
めっきまま鋼板についてＪＩＳ−２−８７４１に規定さ
れる鏡面光沢度測定法（方法名２０度鏡面光沢法）によ
り光沢度の測定を行った。この結果、光沢度Ｇｓ（２０

％の測定値が得られた。Steel plate feed speed: 20-20-3O Roll used: Bright finish Rolling load: 200-300Ton (IIA pressure 2-3
Ton/an) Rolling ratio: 0.5 to 1% Specular gloss measurement method specified in JIS-2-8741 (method name 20 degree specular gloss The glossiness was measured using the following method. As a result, the glossiness Gs (20
°) was 38 to 44% for the as-plated steel sheet, whereas for the present invention material subjected to skin pass rolling, it was 78 to 98%.
% measurements were obtained.
以上述べた本発明によれば、めっき面が非常に光沢があ
