Development of a new generation of high permeability non-oriented silicon steels

Abstract

The paper describes a new generation of the high permeability fully processed silicon steel grades developed by Acesita, with core loss ( W 1.5/60) in range of 3.10–4.20 W/kg and polarisation ( J 50) from 1.71 to 1.75 T, respectively. The new grades have lower (Si+Al) content and a better crystallographic texture, with lower fractions of [1 1 1]||ND fibre and higher fractions of [0 0 1]||RD fibre. The new grades have better mechanical and magnetic properties than conventional grades.
