Abstract

The invention relates to high magnetic induction oriented silicon steel and a preparation method thereof. The oriented silicon steel comprises the following chemical elements by weight percent: 0.035-0.120% of C, 2.9-4.5% of Si, 0.05-0.20% of Mn, 0.005-0.050% of P, 0.005-0.012% of S, 0.015-0.035% of Als, 0.001-0.010% of N, 0.05-0.30% of Cr, 0.005-0.090% of Sn, not more than 0.0100% of V, not more than 0.0100% of Ti, at least one of trace elements of Sb, Bi, Nb and Mo, and the balance of Fe and other inevitable impurities, wherein Sb+Bi+Nb+Mo is 0.0015-0.0250% and (Sb/121.8+Bi/209.0+Nb/92.9+Mo/95.9)/(Ti/47.9+V/50.9) ranges from 0.1 to 15.
