Effects of rolling temperature on microstructure, texture, formability and magnetic properties in strip casting Fe-6.5 wt% Si non-oriented electrical steel

Fe-6.5 wt% Si non-oriented electrical steel sheets with a thickness of 0.50 mm were produced by using a new processing route: strip casting followed by hot rotting, intermediate temperature (150-850[degrees]C) rolling and final annealing. The present study focused on exploring the effects of rolling...

Description
Summary:Fe-6.5 wt% Si non-oriented electrical steel sheets with a thickness of 0.50 mm were produced by using a new processing route: strip casting followed by hot rotting, intermediate temperature (150-850[degrees]C) rolling and final annealing. The present study focused on exploring the effects of rolling temperature varying from 150 to 850[degrees]C on the microstructure and texture evolution, the formability and final magnetic properties. The microstructure and texture evolution at the various processing steps were investigated in detail by using OM, XRD, EBSD and TEM. It was found that the formability during rolling, the microstructure and texture before and after annealing and final magnetic properties highly depended on rolling temperature. Accordingly, on the whole, both the magnetic induction (B[sub 8] and B[sub 50]) and iron loss (P[sub 15/50] and P[sub 10/400]) decreased with raising rolling temperature.
