Abstract

De conformidad con la presente invención, una lámina de acero eléctrico de grano orientado en la cual la pérdida de fierro se ha reducido aún más, se puede obtener llevando a cabo recocido de descarburización como recocido continuo que incluye: calentar la lámina de acero a una temperatura en el intervalo de 700 °C a 750 °C a una velocidad de calentamiento de 50 °C/segundo o mayor por lo menos en un intervalo de temperatura de 500 ºC a 700 °C en una atmósfera que tiene un potencial de oxidación P(H2O) /P (H2) igual a o menor de 0.05; posteriormente enfriar la lámina de acero a un intervalo de temperatura por debajo de 700 °C en una atmósfera que tiene un potencial de oxidación P(H2O) /P (H2) igual a o menor de 0.05; y recalentar la lámina de acero a una temperatura en el intervalo de 800 °C a 900 °C y retener la lámina de acero a la temperatura para homogenizar en una atmósfera que tiene un potencial de oxidación P(H2O) /P (H2) igual a o menor de 0.03.
