Title: (100)[OVW] NON-ORIENTED ELECTRICAL STEEL SHEET WITH EXCELLENT MAGNETIC PROPERTY AND MANUFACTURING METHOD THEREOF
Abstract:
The present invention relates to a non-oriented electrical steel sheet used as an iron core of an electrical device such as a motor and a transformer, and a manufacturing method thereof. Provided is a method for manufacturing a (100)[Ovw] non-oriented electrical steel sheet with an excellent magnetic property according to one embodiment of the present invention, comprising the steps of: hot-rolling, pickling, and cold-rolling a slab of a component composition indicating a ferrite organization in an entire temperature range containing S of 0.0001 to 0.035 wt% and Fe and inevitable impurities of the residual wt%; and forming a surface of an annealing plate in the (100)[Ovw] crystallization direction by annealing a surface of a cold-rolled steel sheet so as to selectively grow crystals of (100) grains on the surface of the cold-rolled steel sheet.
