Abstract
A method for detecting electromagnetic property of oriented silicon steel, the method comprises: measuring Euler angles of each of crystal grains in a specimen by use of metallographic etch-pit method; calculating orientation deviation angle θ(degree) of the crystal grain; combining area Si (mm) of the crystal grain and correction coefficient X of element Si (X=0.1˜10 T/degree); correcting on the basis of the magnetic property B(saturation magnetic induction, T) of single-crystal material by using these parameters (θ, S, X), formula for correcting is
