Description
図2は、本発明の実施形態による凸条付き金属板の製造に使用される製造設備列の一例を示す模式図である。本実施形態では、凸条付き金属板として凸条付きの鋼板10を製造する場合を例示する。つまり、凸条付き金属板の素材として鋼のスラブ30を適用する場合を例示する。
A=(t0−t1)/t0×100[%] …(1)
式(1)中、t0は、特定スタンドにおける圧下前の鋼シート31の板厚を示し、t1は圧下後の鋼板10における凸条間凹部12の最小板厚を示す。
最大圧下率の設定及び調整は、特定スタンドのロール軸間調整機構によって行われる。
上記した凸条付きの鋼板10は、プレス加工によって成形される構造部品のブランクとして用いられる。構造部品の製造にあたり、鋼板10は、構造部品となるプレス成形品に適合する形状に切断される。切断に先立ち、鋼板10には、溶融亜鉛めっき、合金化溶融亜鉛めっき、電気亜鉛めっき、アルミめっき等が施される。また、めっき施工の前に、酸洗、ショットブラスト等によって、鋼板10の表面の酸化膜が除去される。もっとも、酸洗、ショットブラスト、めっき施工等は、プレス加工の前までに実施されていればよく、鋼板10から切り出されたブランクに実施されても構わない。なお、構造部品の仕様に応じ、めっき施工が省略される場合もある。
