Abstract

　レーザ照射を行って鉄損を低減する方向性電磁鋼板の製造方法において、Ｌ、Ｃ両方向の鉄損を高いレベルで改善し、かつ、簡単で生産性の高い製造方法を提供する。 円形または楕円形に集光した連続波レーザ光を、鋼板の圧延方向に概垂直方向に一定間隔で走査照射して鉄損を低減する方向性電磁鋼板の製造方法であって、レーザ光の平均パワーをＰ（Ｗ）、ビームの走査速度をＶｃ（ｍ／ｓ）、圧延方向の照射間隔をＰＬ（ｍｍ）とし、平均照射エネルギー密度ＵａをＵａ＝Ｐ／（Ｖｃ×ＰＬ）（ｍＪ／ｍｍ2）と定義し、ＰＬとＵａの範囲を以下とする。 １．０ｍｍ≦ＰＬ≦３．０ｍｍ 　　０．８ｍＪ／ｍｍ2≦Ｕａ≦２．０ｍＪ／ｍｍ2
