Abstract

Provided is an anisotropic electromagnetic steel sheet comprising by mass% 0.005% or less of C 0.1% to 2.0% of Si 0.05 to 0.6% of Mn 0.100% or less of P and 0.5% or less of Al wherein the content of nonmagnetic precipitate AlN having an average diameter of 10 to 200 nm is by number density 10 precipitates/µm or less and the average flux density in the rolling direction and the direction perpendicular to rolling is 1.75 T or greater. This anisotropic electromagnetic steel sheet can be produced by two methods the method of hot rolling and annealing at a temperature between 750ºC and the Ac1 transformation temperature and the method of self annealing at a coil take up temperature of 780ºC or greater.
