PURPOSE:To enhance a self-caulking property of a steel-plate laminate by keeping a sulfur content in an electromagnetic steel plate as small as 0.01wt.% or smaller. CONSTITUTION:A surfur content in silicon steel is set to be 0.01wt.% or lower. In this case, since surfur is contained, MnS existing in the steel has a property to increase an easy-to-slide characteristic of the steel; as a result, a uniting force of laminated steel plates is reduced. Although a silicon content is not regulated, it is kept necessarily to be 4% or smaller because a rolling operation is executed. By this setup, a self-caulking property of a steel-plate laminate can be enhanced. |
