Description
本出願は、2001年9月13日に出願された米国仮特許出願第60/318,970号(Schoen他)に関連し、優先権を主張する。
粒子方向性電磁鋼は磁心材料として、特に板の圧延と平行の板方向に発達する方向性の磁気特性を利用できる変圧器など、様々な電気機械および機器に広く用いられている。粒子方向性電磁鋼の典型的な適用例として、電源変圧器、配電変圧器、大型発電機、および多種多様な小型変圧器の磁心が挙げられる。磁心の形状としては、大型発電機用のせん断平坦ラミネーション、巻心、セグメントラミネーション、「E」および「I」タイプが挙げられる。
本発明は、鋼をさらに加工することにより(110)[001]粒子方向性電磁鋼を得るのに好適なストリップの製造方法であって、
a.厚さ0.39in(10mm)以下の鋳造ストリップを得る工程と、
b.鋳造ストリップを熱間圧延する工程と、
c.熱間圧延されたストリップを焼鈍する工程と
を行うことによって、歪/再結晶化パラメータ(K*)−1 が約6,500以上となるようにし、(K*)−1は、
THBAはストリップの焼鈍温度(°ケルビン)であり、
THRはストリップの熱間圧延温度(°ケルビン)であり、
t c は熱間圧延前の初期ストリップ厚であり、
tfは熱間圧延後の最終ストリップ厚である、ストリップの製造方法を提供する。
高品質な(110)[001]粒子方向性電磁鋼板の製造では、2次粒子成長の開始前に鋼板が再結晶化ミクロ構造を有している必要がある。再結晶化ミクロ構造は、他方向性の1次粒子マトリックス内で(110)[001]2次粒子を形成する核粒子からなり、他方向性の1次粒子は(110)[001]2次粒子の成長によりすぐに消費される。従来の厚スラブ鋳造では、ミクロ構造および組織の発達が、スラブ再加熱およびストリップ熱間圧延プロセスにより起こることは既知である。熱間圧延されたストリップのミクロ構造中に存在する大量の未再結晶化(または「耐熱性」)粒子が、最終粒子方向性電磁鋼板の所望の(110)[001]方位の発達を損なう可能性があることもまた既知である。
