Mn:0.10%以上5.00%以下、
S:0.0200%以下、
P:0.200%以下、
N:0.0050%以下および
O:0.0200%以下
含有し、残部はFeおよび不可避不純物である成分組成を有し、Ar3変態点が700℃以上、結晶粒径が80μm以上200μm以下、ビッカース硬度が140HV以上230HV以下であることを特徴とする無方向性電磁鋼板。
質量%で、
Ge:0.0500%以下
であることを特徴とする、上記1に記載の無方向性電磁鋼板。
質量%で、
Ti:0.0030%以下、
Nb:0.0030%以下、
V:0.0030%以下および
Zr:0.0020%以下
の少なくともいずれかであることを特徴とする、上記1または2に記載の無方向性電磁鋼板。
最初に、磁気特性に及ぼす二相域の影響について調査するため、表1の成分組成を含有する鋼Aから鋼Cを実験室にて溶製し、熱間圧延を行った。熱間圧延は7パスで行い、熱延の初パス(F1)の入り側温度は1030℃、熱延の最終パス(F7)入り側温度は910℃とした。
Cは磁気時効防止の観点から0.0050%以下とする。一方、Cは磁束密度を向上させる効果があるため0.0010%以上が好ましい。
Siは鋼板の固有抵抗を上げるために有効な元素であるため1.50%以上とする。一方、4.00%を超えると飽和磁束密度の低下に伴い磁束密度が低下するため上限は4.00%とする。好ましくは、3.00%以下とする。これは3.00%を超えると二相域とするために多量のMnを添加する必要があり、いたずらにコストアップとなるためである。
Alはγ域閉鎖型の元素であるため少ないほうが好ましく、0.500%以下、好ましくは0.020%以下、より好ましくは0.002%以下とする。
Mnはγ域を拡大するために効果的な元素であるため、下限を0.10%とする。一方、5.00%超になると磁束密度を低下させるので上限を5.00%とする。好ましくは、3.00%以下とする。これは3.00%を超えるといたずらにコストアップとなるためである。
Sは0.0200%を超えるとMnSの析出により鉄損が増大するため、上限を0.0200%とする。
Pは0.200%を超えて添加すると鋼板が硬くなるため0.200%以下、より好ましくは0.100%以下とする。さらに好ましくは0.010〜0.050%とする。これはPが表面偏析して窒化を抑制する効果があるためである。
Nは、含有量が多い場合にはAlNの析出量が多くなり、鉄損を増大させるため0.0050%以下とする。
Oは、含有量が多い場合には酸化物が多くなり、鉄損を増大させるため0.0200%以下とする。
Geは半導体に使用されることからスクラップに混入しやすくなっている元素であるが、0.0500%を超えると熱延後の再結晶が抑制され、磁束密度が低下するおそれがあるため上限を0.0500%とする。
Tiは、含有量が多い場合にはTiNの析出量が多くなり、鉄損を増大させるおそれがあるため0.0030%以下とする。
Nbは、含有量が多い場合にはNbCの析出量が多くなり、鉄損を増大させるおそれがあるため0.0030%以下とする。
Vは、含有量が多い場合にはVN、VCの析出量が多くなり、鉄損を増大させるおそれがあるため0.0030%以下とする。
Zrは、含有量が多い場合にはZrNの析出量が多くなり、鉄損を増大させるおそれがあるため0.0020%以下とする。
転炉で吹練した溶鋼を脱ガス処理し、表3の成分に鋳造後、1140℃×1hのスラブ加熱を行い、板厚2.0mmまで熱間圧延を行った。熱間の仕上圧延は7パスで行い、初パスおよび最終パスの入り側板温は表3に示す温度とし、巻き取り温度は670℃とした。その後、酸洗を行い、板厚0.5mmまで冷間圧延を行い、20%H2−80%N2雰囲気で表3に示す条件において仕上焼鈍を行い、磁気特性(W15/50,B50)および硬度(HV)を評価した。磁気測定は圧延方向および圧延直角方向よりエプスタインサンプルを切り出し、エプスタイン測定を行った。ビッカース硬度はJIS Z2244に準拠し、鋼板断面に500gのダイヤモンド圧子を押し込むことにより測定した。結晶粒径は断面を研磨し、ナイタールにてエッチングした後、JIS G0551に準拠して測定した。
