Abstract

　質量％または質量ppmで、Ｃ：0.08％以下、Si：2.0～4.5％およびMn：0.5％以下を含有すると共に、Ｓ，SeおよびＯをそれぞれ50ppm未満、sol.Alを100ppm未満に抑制し、さらにＮを[sol.Al]×（14/27）ppm≦Ｎ≦80ppmの範囲に制御し、残部はFeおよび不可避的不純物の組成からなる鋼スラブを素材として、方向性電磁鋼板を製造するに際し、冷間圧延後、二次再結晶焼鈍開始前までに、窒素量が50質量ppm以上1000質量ppm以下となる窒化処理を施し、焼鈍分離剤中に硫化物および／または硫酸塩を合計で0.2～15質量％含有させ、二次再結晶焼鈍の昇温過程において300～800℃の温度域における滞留時間を５時間以上確保して、窒化珪素（Si3N4）およびMnＳを析出させ、この窒化珪素とMnＳを正常粒成長の抑制力として併用することにより、磁気特性のバラツキを大幅に低減して、良好な特性を有する方向性電磁鋼板を工業的に安定して製造する。
