| description | The invention discloses high-magnetic-induction oriented silicon steel which comprises the following chemical elements in percentage by mass besides Fe and other inevitable impurities: 2.5-4.5% of Si; 0.03 to 0.08% of C; the content of Als is 0.015 to 0.035 percent; 0.001% < = N < 0.004%; mn: 0.05 to 0.20%; 0.001% to 0.02% of S; the rare earth element is at least one of Ce and La, and the sum of Ce and La is 0.001-0.2%; wherein in other inevitable impurity elements, V is controlled to be smaller than or equal to 0.005%, and Ti is controlled to be smaller than or equal to 0.005%. Correspondingly, the invention further provides a manufacturing method of the high-magnetic-induction oriented silicon steel. According to the method, under the condition that the heat treatment temperature is properly reduced, the secondary grain orientation degree is improved, the secondary grain size is not increased, and the comprehensive magnetic performance of low iron loss, high magnetic induction intensity and low magnetostric |
