Abstract

所定の成分組成からなるスラブを、スラブ加熱後、粗圧延および仕上圧延からなる熱間圧延を施し、ついで熱延板焼鈍を施し、酸洗後、１回の冷間圧延によって最終板厚としたのち、仕上焼鈍を施す一連の工程によって高強度電磁鋼板を製造するに際し、上記粗圧延における累積圧下率を73.0％以上とし、上記熱延板焼鈍工程において、焼鈍温度：850℃以上1000℃以下、焼鈍時間：10秒以上10分以下の条件下で、熱延板焼鈍後の鋼板圧延方向断面における再結晶粒の面積率が100％で、かつ再結晶粒径が80μm以上300μm以下となる焼鈍条件を選定すると共に、上記仕上焼鈍工程において、焼鈍温度：670℃以上800℃以下、焼鈍時間：２秒以上１分以内の条件下で、仕上焼鈍後の鋼板圧延方向断面における再結晶粒の面積率が30％以上95％以下で、かつ連結した未再結晶粒群の圧延方向の長さが2.5mm以下となる焼鈍条件を選定する。
