Description
a)メッキ原板が酸洗済みの熱延鋼板であり、鋼板成分としてSiが0.2質量%以上の場合には、Niプレメッキ量を0.5g/m2以上とし、
b)メッキ原板が酸洗済みの熱延鋼板であり、鋼板成分としてSiが0.2質量%未満の場合には、Niプレメッキ量を0.2g/m2以上とし、
c)メッキ原板が焼鈍済みの冷延鋼板であり、鋼板成分としてSiが0.2質量%以上の場合には、Niプレメッキ量を0.3g/m2以上とし、
d)メッキ原板が焼鈍済みの冷延鋼板であり、鋼板成分としてSiが0.2質量%未満の場合には、Niプレメッキ量を0.05〜0.35g/m2以上とする
ことが不メッキ欠陥発生のない溶融亜鉛メッキを施すために必要である。この方法はZnを含有する各種の合金メッキにも適用可能である。
冷延、焼鈍済みの材料としては、公知の方法によって製造されいずれのものも可能であるが、いわゆる気水冷却等の水を利用する冷却を経た鋼板は表層にスケールが残存することから、これを酸洗除去したものが望ましい。
本発明におけるNiプレメッキの前処理として、表面の汚れ、酸化膜等を除去する清浄化処理が必要である。この方法としては、アルカリ脱脂と酸洗処理をこの順で実施することが望ましい。
まず、メッキ原板が酸洗済みの熱延鋼板の場合、Niプレメッキ量は0.2g/m2 以上必要で、これ未満では不メッキとなる。さらに、熱延鋼板で鋼中にSiを0.2%以上含有するものは、より不メッキが発生しやすくなり、Niプレメッキ量としては0.5g/m2 以上必要になる。
Niプレメッキ量の上限については特に限定されないが、コストの点からは低い方が望ましいので、Niプレメッキの設備の能力を勘案して、前述の下限値を割らないような条件を上限とするのが望ましい。
このように、コスト的も考慮した本発明における最も有利な形態を図1に示す。図1は各メッキ原板でのNiプレメッキ量の好ましい範囲を示したものである。
またこの浴に更にMgを0.01〜1.0%含有させることで、耐食性の良好な溶融亜鉛メッキ鋼板が製造できる。この浴に更にNi,Co,Ti,Pb,Bi,Sb,Sn,Si等を0.001〜0.1%程度の微量添加することも可能である。
また、以上のようにして製造した溶融亜鉛メッキ鋼板を公知の方法で加熱処理すれば、合金化溶融亜鉛メッキ鋼板の製造も可能である。
また更にSiを0.01〜1.0%含有させ、耐食性の更に良好なZn−Al−Mg−Si合金溶融亜鉛メッキ鋼板も可能である。
また、溶融亜鉛メッキ浴にAlを15〜80%多量に含有させて、耐食性の更に良好なZn−Al合金溶融亜鉛メッキ鋼板も可能である。更にSiを0.01〜1.0%含有させ、耐食性の更に良好なZn−Al−Si合金溶融亜鉛メッキ鋼板も可能である。
表1に示した7種のメッキ原板を用いた。メッキ原板1〜4は焼鈍済みの冷延鋼板、5〜6は酸洗済みの熱延鋼板である。表2に示す前処理の後、表3に示すメッキ浴にて電気メッキ(浴温60℃、電流密度30A/dm2 )にてNiプレメッキを行なった。
その後、3%H2 +N2 雰囲気中で50℃/secの昇温速度にて460℃まで加熱し、ただちに450℃に保温した溶融Znメッキ浴に浸漬し3sec 保持の後、ワイピングして目付けを調整した。目付けは60g/m2 とした。
実施例2では、溶融メッキ浴として、0.2%Alと0.5%Mgを添加したものを用い、Niプレメッキ量は、表4に示すように各メッキ原板で相違させた。
実施例3では、溶融メッキ浴として、10%Alと3%Mgと0.2%Siを添加したものを用い、Niプレメッキ量は、表4に示すように各メッキ原板で相違させた。
実施例4では、溶融メッキ浴として、55%Alと0.2%Siを添加したものを用い、Niプレメッキ量は、表4に示すように各メッキ原板で相違させた。
各サンプルでメッキ後外観を目視観察し、不メッキ等の異常の有無を確認した。
表4に示すように、本発明の条件によれば、いずれのメッキ原板にも良好な溶融亜鉛メッキを施すことが出来た。
