The invention discloses oriented silicon steel and a preparation method thereof, and the oriented silicon steel is prepared by smelting the following components in percentage by mass: 0.03-0.05% of C; s < i >: 2.8 to 3.3; 0.10 to 0.50% of Mn; p: less than or equal to 0.020; 0.005 to 0.010 percent of S; the A < l > is 0.015 to 0.025; 0.40 to 0.60% of Cu; the invention is suitable for oriented silicon steel production, Al and N with large mass fraction control fluctuation range in chemical components are classified, batch materials are re-grouped according to the classification condition, and a corresponding production process is formulated, so that the stability of inhibitor control is realized, the production efficiency is improved, the production cost is reduced, and the production cost is reduced. And the stability of the magnetic performance of the finished product is realized. 本发明公开了一种取向硅钢及其制备方法，按质量百分比，由以下成分冶炼而成，C：0.03～0.05；S i：2.8～3.3；Mn：0.10～0.50；P：≤0.020；S：0.005～0.010；A l：0.015～0.025；Cu：0.40～0.60；N：0.0
