NON-ORIENTED MAGNETIC STEEL SHEET WITH SUPERIOR WORKABILITY AND A MANUFACTURING METHOD THEREOF, CAPABLE OF OPTIMIZING THE ANNEALING CONDITION OF COLD ROLLING

摘要

PURPOSE: A non-oriented magnetic steel sheet with superior workability and a manufacturing method thereof are provided to maintain the fraction of a high cube texture by uniformly annealing a cold rolling plate.;CONSTITUTION: A non-oriented magnetic steel sheet with superior workability comprises Si 0.2~1.0 weight%, Al 0.9~2.0 weight%, Mn 0.1~0.5 weight%, P 0.01~0.05 weight%, and the rest including Fe and inevitable impurities. A non-oriented magnetic steel sheet of the cube texture of the cross section is 5% or greater after SRA operation.;COPYRIGHT KIPO 2010
