Abstract
Non-oriented silicon steel sheets having an excellent electromagnetic property is obtained by annealing a hot rolled steel sheet containing not moe than 0.02% of C, 0.5-3.5% of Si, 0.1-1.0% of Al, 0.1-1.0% of Mn, not more than 0.007% of S and 0.005-0.30% of Sb at a temperature of 700.degree.-950.degree. C., cold rolling the annealed sheet, and annealing the cold rolled sheet at a temperature of 750.degree.-1,000.degree. C.
