High-magnetic-induction grain-oriented silicon steel and preparation method thereof

Abstract

Disclosed are a high-magnetic-induction grain-oriented silicon steel and a preparation method thereof. The preparation method comprises the following steps: heating a hot-rolled strip steel and then subjecting the same to a cold continuous rolling by using a cold continuous rolling mill with work-roll diameters ranging from 300 mm to 500 mm, to obtain a cold continuous rolled strip steel; and sequentially subjecting the cold continuous rolled strip steel to a decarburization and nitriding, to obtain the high-magnetic-induction grain-oriented silicon steel.
