Resumo
In this study, a steel for semiprocessed electrical purposes of non-oriented grain with
approximately 0.05% carbon content and 0.02% silicon content was evaluated. Lamellas with kind
of thicknesses 0.58 mm, 0,66 mm and 0.87 mm were processed on an industrial scale with a strain
rate in the hardening lamination between 3 and 5%. The magnetic properties were evaluated after
the wet heat treatment. The loss separation method was applied, estimating the hysteretic plot with
hysteresis measure in the quasi static condition and the parasitic losses calculated according to
Thomson's Equation. By increasing grain size, permeability increases and coercivity decreases.
However, in the case of losses, there is an optimum grain size. After the procedure of separation of
losses, it was observed that increase of thickness results in increase of the anomalous parcel of
magnetic losses.
