Description
(1)C:0.020%超え0.040%未満
本発明に係る高強度高加工性鋼板では、C(炭素)の含有量を低めに抑えることで高加工性を発揮する。Cの含有量が0.040%以上であると、鋼板が過剰に硬質となり、加工性を確保したまま二次冷間圧延で薄い鋼板を製造することが不可能となる。このため、Cの含有量の上限は0.040%未満とする。一方、Cの含有量が0.020%以下であると、鋼板の薄肉化による顕著な経済効果を得るために必要な引張強度520MPaが得られない。このため、Cの含有量の下限は0.020%超えとする。
Si(ケイ素)の含有量が0.100%を超えると、表面処理性の低下、耐食性の劣化等の問題を引き起こす。このため、Siの含有量の上限は0.100%とする。一方、Siの含有量を0.003%未満とするには精錬コストが過大となる。このため、Siの含有量の下限は0.003%とする。好ましいSiの含有量は、0.003%以上0.035%以下の範囲内である。
Mn(マンガン)は、S(硫黄)による熱延中の赤熱脆性を防止し、結晶粒を微細化する作用を有し、望ましい材質を確保する上で必要な元素である。これらの効果を発揮するためには、少なくとも0.10%以上のMnの添加が必要である。一方、Mnを多量に添加し過ぎると、耐食性が劣化し、また鋼板が過剰に硬質化する。このため、Mnの含有量の上限は0.60%とする。好ましいMnの含有量は、0.19%以上0.60%以下の範囲内である。
P(リン)は、鋼を硬質化させ、加工性を悪化させると同時に、耐食性をも悪化させる有害な元素である。このため、Pの含有量の上限は0.100%とする。一方、Pの含有量を0.001%未満とするには脱リンコストが過大となる。このため、Pの含有量の下限は0.001%とする。好ましいPの含有量は、0.001%以上0.015%以下の範囲内である。
Sは、鋼中で介在物として存在し、加工性の低下、耐食性の劣化をもたらす有害な元素である。このため、Sの含有量の上限は0.020%とする。一方、Sの含有量を0.001%未満とするには脱硫コストが過大となる。このため、Sの含有量の下限は0.001%とする。好ましいPの含有量は、0.007%以上0.014%以下の範囲内である。
Al(アルミニウム)は、製鋼時の脱酸材として必要な元素である。Alの含有量が少ないと、脱酸が不十分となり、介在物が増加し、加工性が劣化する。Alの含有量が0.005%以上であれば十分に脱酸が行われているとみなすことができる。一方、Alの含有量が0.100%を超えると、アルミナクラスター等に起因する表面欠陥の発生頻度が増加する。このため、Alの含有量は0.005%以上0.100%以下とする。
本発明に係る高強度高加工性鋼板においては、Cの含有量を低めとする代わりにN(窒素)の含有量を高めとし、強度を確保する。Nによる強化は張り出し加工性に及ぼす影響が小さいため、エリクセン値を損なわずに鋼板の高強度化が可能である。Nの含有量が0.0130%以下であると、缶蓋に必要となる強度が得られない。一方、Nは多量に添加すると、熱間延性が劣化し、連続鋳造においてスラブの割れが発生する。このため、Nの含有量の上限は0.0170%とする。
上記成分以外の残部はFe(鉄)及び不可避的不純物とするが、公知の溶接缶用鋼板中に一般的に含有される成分元素を含有していても良い。例えば、Cr(クロム):0.10%以下、Cu(銅):0.20%以下、Ni(ニッケル):0.15%以下、Mo(モリブデン):0.05%以下、Ti(チタン):0.3%以下、Nb(ニオブ):0.3%以下、Zr(ジルコニウム):0.3%以下、V(バナジウム):0.3%以下、Ca(カルシウム):0.01%以下等の成分元素を目的に応じて含有させることができる。
次に、本発明に係る高強度高加工性鋼板の機械的性質について説明する。
次に、本発明に係る高強度高加工性鋼板の表面被覆について説明する。
次に、本発明に係る高強度高加工性鋼板の製造方法について説明する。
表1に示す成分組成を含有し、残部がFe及び不可避的不純物からなる鋼を実機転炉で溶製し、連続鋳造法により鋼スラブを得た。得られた鋼スラブを再加熱した後、表2に示す条件で熱間圧延を施した。熱間圧延の仕上げ圧延温度は880℃とし、圧延後には酸洗を施した。次に、圧延率90%で一次冷間圧延を行った後、表2に示す条件で連続焼鈍及び二次冷間圧延を施した。以上により得られた鋼板に電解Cr酸処理を両面に連続的に施して、片面Cr付着量100mg/m2のティンフリースチールを得た。そして、さらに共重合比12mol%のイソフタル酸共重合ポリエチレンテレフタラートフィルムを両面にラミネートして、樹脂被覆鋼板を得た。ラミネートは、245℃に加熱した鋼板とフィルムとを一対のゴムロールで挟んでフィルムを金属板に融着させ、ゴムロール通過後1秒以内に水冷して行った。このとき、鋼板の送り速度は40m/min、ゴムロールのニップ長は17mmであった。ニップ長とは、ゴムロールと鋼板とが接する部分の搬送方向の長さのことである。フィルム層の厚さを表1に示す。
