Abstract

Para mejorar y estabilizar las propiedades magnéticas, una lámina de acero se remoja en un intervalo de temperatura de 1000°C o más y 1120°C o menos durante 200 seg o menos y luego se remoja en un intervalo de temperatura de 650°C o más y 1000°C o menos durante 200 seg o menos en recocido antes de la laminación en frío final, y la cantidad de Al en los precipitados después del recocido antes del laminado en frío final se limita a 50 % o más de la cantidad total de Al contenida en la plancha de acero.
