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

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 [111]parallel to ND fibre and higher fractions of [001]parallel to RD fibre. The new grades have better mechanical and magnetic properties than conventional grades. (C) 2006 Elsevier B.V. All rights reserved.
