Abstract
Description
(1)主要なインヒビターとしてMnS又はMnSeを用いるため、最終製品の磁気特性が比較的低い。
(2)MnS又はMnSeインヒビターを充分に固溶させるために加熱温度を最高で1400℃まで到達させる必要があり、これは従来の加熱炉では限界温度である。また、加熱温度が高く、焼損が大きいため、加熱炉を頻繁に修理する必要があり、稼働率が低い。また、加熱温度が高いとエネルギー消費が大きく、熱延コイルのエッジクラックがひどいため、冷延工程による生産が困難であり、歩留りが低下し、コストが上昇する。
(3)従来の化学成分系では、全製造過程において焼準、中間焼鈍及び二回冷間圧延法を行わなければ、好適な磁気特性を有する汎用方向性ケイ素鋼製品は得られず、そのため手順が複雑になり、製造工程フローが長くなり、生産効率が低い。
(4)従来の汎用方向性ケイ素鋼の場合、MnS又はMnSeは完全固溶非窒化型であり、実際の製造においてはスラブの再加熱温度が非常に高いため、スラブ中のインヒビター強度は均一ではなく、粗大な結晶粒等が生成され易い。そのため、二次再結晶が不充分となり、磁束密度等が低下してしまうという問題がある。
(1)N含量を0.002〜0.014重量%に制限した製錬と、連続鋳造とを行ってスラブを得る工程;
(2)加熱温度を1090〜1200℃とした熱間圧延工程;
(3)時効を省略した一次圧延を行う冷間圧延工程;
(4)脱炭焼鈍工程;
(5)浸透窒素含量[N]Dを下記式:
