Abstract | This method of manufacturing a grain-oriented electrical steel sheet involves controlling the degree of oxidation (PH2O/PH2) in a decarburization annealing step, controlling the mass ratio of MgO and Al2O3 within an annealing separator in an annealing separator application step, controlling the degree of oxidation in the case that hydrogen is present or controlling the dew point in the case that only an inert gas is present in a final annealing step, and controlling the baking temperature and the heat treatment temperature in an insulating coating film formation step.
L'invention concerne un procédé de fabrication d'une tôle d'acier magnétique à grains orientés, comprenant le réglage du degré d'oxydation (PH2O/PH2) dans une étape de recuit de décarburation, le réglage du rapport massique de MgO et d'Al2O3 au sein d'un séparateur de recuit dans une étape d'application de séparateur de recuit, le réglage du degré d'oxydation dans le cas où de l'hydrogène est présent ou le réglage du point de rosée dans le cas où seul un gaz inerte est présent dans une étape de recuit final et le réglage de la température de cuisson et de la température de traitement thermique dans une étape de formation de film de revêtement isolant.
この方向性電磁鋼板の製造方法は、脱炭焼鈍工程で酸化度PH2O/PH2を制御し、焼鈍分離剤塗布工程で焼鈍分離剤のMgOとAl2O3との質量比率を制御し、仕上げ焼鈍工程で水素を含有する場合には酸化度を不活性ガスからなる場合には露点を制御し、絶縁被膜形成工程で焼付け温度および熱処理温度を制御する。 |
