Description
方向性電磁鋼板の磁気特性は、Goss集合組織と呼ばれる特別な集合組織を形成することによって発現し、磁化容易方向が略圧延方向となる。この集合組織は、冷間圧延と焼鈍処理とによって制御される。
例えば非特許文献1は、リン酸塩と、コロイダルシリカと、水と、三酸化クロムまたはクロム酸とを含む絶縁皮膜形成用組成物を開示している。この組成物を鋼板の表面に塗布し、例えば840〜920℃の温度範囲内で焼き付けることにより、表面に絶縁皮膜(リン酸塩・シリカ層)が形成される。
本発明の上記態様に係る方向性電磁鋼板は、本発明の上記態様に係る絶縁皮膜形成用組成物を用いて形成された緻密な絶縁皮膜を備えるので、この方向性電磁鋼板は、絶縁性、耐熱性、耐化学性、化学的安全性に優れるとともに、鋼板に対して高い張力が付与されるため磁気特性にも優れる。
従来のコロイダルシリカはNa+を含む水溶液によって安定化されたものであり、従来のコロイダルシリカの表面にはSi−O−が配置されている。これに対して、アルミン酸塩によって表面修飾されたシリカを含むコロイダルシリカは、シリカ粒子の表面にAl−OH−が配置されているので、従来のコロイダルシリカに比べてさらに安定化されている。例えば、安定化のメカニズムについて、R.K.Iler、“The Effect of Surface Aluminosilicate Ions on the Properties of Colloidal Silica、”Journal of Colloidal and Interface Science、vol.55、No.1、p25−34に記載されている。また、例えば、表面修飾によるシリカゾルの特性改質方法について、米国特許第2892797号に記載されている。
従って、本実施形態に係る絶縁皮膜形成用組成物では、アルミン酸塩によって表面修飾されたシリカを含むコロイダルシリカ、またはアルミン酸塩が添加されたコロイダルシリカを用いる。
絶縁皮膜13は、31P核磁気共鳴(NMR)スペクトルにおいて、H3PO4溶液を基準とする化学シフトとして−30〜−40ppmに特徴的なピークまたはショルダを有してもよい。例えば、絶縁皮膜13は、クロムフリーであり、そして31P化学シフトの基準として85質量%H3PO4溶液を用いたとき、リンに関して、絶縁皮膜13の31PのNMRスペクトルが−35ppm近辺に31P化学シフトを示すような化学構造を含んでもよい。また、各ピーク位置を0〜−60ppmの範囲とするガウシアンフィッティングによって−35ppm近辺の31P化学シフトのピーク面積および全ピーク面積を求めたとき、−35ppm近辺の31P化学シフトのピーク面積は、全ピーク面積の30%超となる。
本実施形態に係る方向性電磁鋼板10の製造方法は、図4のフロー図に示すように、鋳造工程S01と、熱間圧延工程S02と、熱延板焼鈍工程S03と、冷間圧延工程S04と、脱炭焼鈍工程S05と、焼鈍分離剤塗布工程S06と、仕上焼鈍工程S07と、絶縁皮膜形成工程S08と、選択的なレーザ照射工程S09と、を有している。
熱間圧延工程S02では、得られたスラブを所定温度(例えば1150〜1400℃)に加熱して熱間圧延を実施する。これにより、例えば厚さ1.8〜3.5mmの熱間圧延板を製出する。
冷間圧延工程S04では、熱延板焼鈍工程S03後、熱間圧延板の表面を酸洗した上で、冷間圧延を実施する。これにより、例えば厚さ0.15〜0.50mmの冷間圧延板を製出する。
焼鈍分離剤塗布工程S06では、酸化物層の上に、焼鈍分離剤を塗布する。この焼鈍分離剤は、主にマグネシア(MgO)を含めばよい。
絶縁皮膜形成工程S08では、形成される絶縁皮膜の量が、1〜10g/m2の範囲内とすればよい。焼き付け温度は、750〜1000℃の範囲内とすればよい。
上述のように、基材11上にグラス皮膜12及び絶縁皮膜13が形成されることで方向性電磁鋼板10が製造でき、レーザ照射によって磁区が御される。
また、本実施形態では、リン酸塩として、リン酸アルミニウム、リン酸マグネシウム、リン酸ニッケル、リン酸マンガン、から選択される少なくとも1種を用いるとき、緻密な絶縁皮膜13を確実に形成できる。
さらに、本実施形態では、上記の組成物が、無水換算で、25〜75質量%のリン酸塩と、75〜25質量%のコロイダルシリカと、を含むとき、この組成物をグラス皮膜11上に塗布して焼き付けることによって緻密な絶縁皮膜13を形成できる。
本実施形態では、絶縁皮膜13の断面における気孔の面積率が10%未満であるとき、絶縁皮膜13が緻密な構造となり、その結果、方向性電磁鋼板10が優れた絶縁性、耐熱性、耐化学性を示す。
これらの特徴より、絶縁皮膜13がクロムを含有しない場合、この絶縁皮膜13は、本実施形態に係る絶縁皮膜形成用組成物によって形成された皮膜であると特定できる。
例えば、基材11(鋼板)及びグラス皮膜12の組成は、本実施形態の組成に限定されず、他の組成の基材(鋼板)及びグラス皮膜に対して絶縁皮膜を形成してもよい。
表1に示すように、含有量が50質量%である金属リン酸塩溶体と、含有量が30質量%であるコロイダルシリカとを用いて、様々な組成の絶縁皮膜形成用組成物(組成物No.1〜19)を準備した。組成物No.17では、アルミン酸塩を3質量%含む混合物(コロイダルシリカ)となるように、従来のコロイダルシリカに対してアルミン酸塩を添加した。また、アルミン酸塩によって表面修飾されたシリカを含むコロイダルシリカとして、2つのサプライヤーから供給された2製品(A、B)を使用した。
クロム酸を含有する組成物No.1と、従来のコロイダルシリカを用いたクロム酸を含有しない組成物No.2と、アルミン酸塩によって表面修飾されたシリカ(シリカ粒子)を含むコロイダルシリカを用いたクロム酸を含有しない組成物No.4と、を準備した。これらの組成物を50℃で保持し、保持時間と粘性との関係について評価した。この評価結果を図5に示す。粘性は、回転粘度計ブルックフィールドDV−II+(スピンドル:LV1、駆動:50rpm)によって測定した。
上述の組成物No.1〜19を、鋼板の表面に塗布して焼き付けた。それにより、表2に示す実施例No.11〜191の絶縁皮膜を製造した。このとき、組成物の塗布量はすべて4.5g/m2とした。焼き付け温度は、表2および表3に示すように、830〜930℃の範囲内とした。
この画像に対して二値化処理を行い、この二値画像から気孔の面積を除いた断面の面積ACを得る(図6の例では、AC=197μm2)。
空隙充填した二値画像から気孔の面積を含めた断面の面積Aを得る(図6の例では、A=260μm2)。
そして、気孔率Fを、F=1−AC/Aから算出した(図6の例では、F=1−197/260=24.1%)。
一方、実施例No.41〜93、111〜163、181、および191では、アルミン酸塩によって表面修飾されたシリカを含むコロイダルシリカを用いた組成物によって絶縁皮膜を形成したので、気孔率が10%未満となり、そして、これらの実施例は、従来のコロイダルシリカを用いたクロム酸またはアルミン酸塩を含有しない組成物によって絶縁皮膜が形成された上記実施例と比較して、緻密な構造を有していた。加えて、実施例No.171〜173では、従来のコロイダルシリカにアルミン酸塩を添加した組成物によって絶縁皮膜を形成したので、気孔率が10%未満となった。
実施例No.22の絶縁皮膜では、気孔が多く観察されたが、実施例No.42の絶縁皮膜では、気孔がほとんど観察されず、緻密な構造が得られた。
気孔率と付与された張力との関係を表2および表3に示す。表2および表3に示すように、気孔率が小さくなるとともに、付与された張力が増加した。
従来のコロイダルシリカを用いたクロム酸を含有する実施例No.12、従来のコロイダルシリカを用いたクロム酸を含有しない実施例No.22、およびアルミン酸塩によって表面修飾されたシリカを含むコロイダルシリカを用いた実施例No.42に関して、31P核磁気共鳴分光法(NMR)によって絶縁皮膜の化学構造を評価した。
10%臭素メタノール溶液を用いて絶縁皮膜を採取し、この採取された3つの絶縁皮膜から31PのNMRスペクトルを得た。31PのNMRスペクトルの化学シフトの基準として85質量%H3PO4溶液を用いた。
一方、実施例No.22の絶縁皮膜の31PのNMRスペクトルは、−30ppmにAl−O−P結合に由来する主なシグナル、およびSi−O−P結合に由来する小さなシグナルを示す。Si−O−P結合に対するAl−O−P結合のピーク面積比は、2つのガウシアンカーブのフィッティングから75:25と計算される。それゆえ、実施例No.22の絶縁皮膜のリンの主な構造は、Al−O−P結合と言える。
これらの結果から、実施例No.22の絶縁皮膜では、ガラス状なSi−O−P結合が形成されにくいので、張力が低下すると考えられる。
