| description | PROBLEM TO BE SOLVED: To provide a method of manufacture of a silicon steel sheet excellent in magnetic properties in two directions orthogonal to each other. SOLUTION: A steel, having a composition which contains, by weight, 0.02-0.2% C and in which the contents of Si and Mn satisfy inequalities Si(%)+0.5Mn(%)=1.5, and Mn(%)>=0.2, is rolled in two directions orthogonal to each other, by which a steel sheet is prepared. Then, annealing is applied under reduced pressure to the steel sheet by using, as a separation agent at annealing, a substance accelerating decarburization or a substance accelerating decarburization and a substance accelerating Mn removal. Further, rolling in two directions orthogonal to each other is carried out in the α+γ two-phase temp. region and then rolling is performed in one direction in the α-phase temp. region, or, rolling in one direction is carried out in the α+γ two-phase temp. region and then rolling is performed in a direction orthogonal to the rolling direction in the α-phase temp. region. |
