Abstract: The quality improvements and researches of grain oriented electrical steels in Aperam South America were introduced, including the production process and product types, the research on AlN precipitation behavior of high magnetic induction oriented electrical steel, the improvement of hot rolling and cold rolling process, effect of magnesia blending on the magnetic properties, secondary recrystallization characteristics, etc. which are useful for the reference research of grain oriented electrical steel.

Key words: Aperam, oriented electrical steel, hot rolling process, magnetic properties
