Abstract

See full text

A non-oriented electrical steel having excellent magnetic properties, the chemical elements thereof in percentage by mass being: Si: 0.2-1.5%, Mn: 0.01-0.30%, Al: 0.001-0.009%, O: 0.005-0.02%, C≤0.005%, S≤0.005%, N≤0.005%, and Ti≤0.002%, the remainder being Fe and other unavoidable impurities, and Al/Si≤0.006 and Mn/Si≤0.2. The method for producing comprises the following sequence of steps: (1) smelting; (2) hot rolling: the slab heating temperature being 850° C. to 1250° C., and the final rolling temperature being 800-1050° C.; (3) acid pickling; (4) cold rolling; (5) annealing: the annealing plate temperature being controlled between 620° C.-900° C.; and (6) coating.
