Description
Up=(4/π)×P/(Dl×Vc) ・・・(式1)
Ip=(4/π)×P/(Dl×Dc)×(1/1000) ・・・(式2)
1≦Up≦10J/mm2 ・・・(式3)
100kW/mm2≦Ip≦2000kW/mm2 ・・・(式4)
ここで、Pはレーザビームの平均強度、すなわちパワー(W)を示し、Dlはレーザビームの集光スポットの圧延方向の径(mm)を示し、Dcはレーザビームの集光スポットの板幅方向の径(mm)を示し、Vcはレーザビームの板幅方向の走査速度(mm/s)を示す。
上述の態様によって得られたグラス皮膜は、方向性電磁鋼板表面の溝部以外のMgの特性X線強度の平均値を1とした場合における溝部のMgの特性X線強度のX線強度比Irが0≦Ir≦0.9の範囲内であることが望ましい。この範囲であれば、良好な鉄損特性が得られる。
上記X線強度比は、EPMA(Electron Probe MicroAnalyser)等を用いて、測定することで得られる。
第1の実験では、方向性電磁鋼用の鋼材の熱間圧延、焼鈍、及び冷間圧延を行い、珪素鋼板の厚さを0.23mmとし、これを巻き取って冷延コイルとした。冷延コイルは5個作製した。続いて、実施例No.1、No.2、No.3にあたる3個の冷延コイルについては、レーザビームの照射による溝の形成を行い、その後に、脱炭焼鈍を行って一次再結晶を生じさせた。レーザビームの照射は、ファイバレーザを使用して行った。いずれもパワーPは2000W、集光形状は、実施例No.1、No.2については、L方向径Dlが0.05mm、C方向径Dcが0.4mmである。実施例No.3については、L方向径Dlが0.04mm、C方向径Dcが0.04mmである。走査速度Vcは、実施例No.1とNo.3が10m/s、実施例No.2が、50m/sとした。従って、瞬時パワー密度Ipは実施例No.1、No.2が127kW/mm2であり、実施例No.3が1600kW/mm2である。照射エネルギー密度Upは、実施例No.1が5.1J/mm2、実施例No.2が1.0J/mm2、実施例No.3が6.4J/mm2である。照射ピッチPLは4mmとし、アシストガスとして空気を15L/分の流量で吹き付けた。この結果、形成された溝の幅は、実施例No.1、No.3が約0.06mmすなわち60μmで、実施例No.2が0.05mmすなわち50μmであった。溝の深さは実施例No.1が約0.02mmすなわち20μmで、実施例No.2が3μm、実施例No.3が30μmであった。幅のばらつきは±5μm以内、深さのばらつきは±2μm以内であった。
第2の実験では、レーザビームの照射条件に関する検証を行った。ここでは、下記の4種の条件でレーザビームの照射を行った。
第3の実験では、アシストガスの流量を10L/分未満とした条件、及びアシストガスを供給しないという条件の2種類の条件でレーザビームの照射を行った。この結果、溝の深さを安定させることが困難であり、溝の幅のばらつきが±10μm以上、深さのばらつきが±5μm以上であった。このため、実施例と比較して磁気特性のばらつきが大きかった。
