| Abstract Scope |
A 1.2 wt% Si non-oriented electrical steel (NOES) was processed using conventional rolling-annealing routes. The hot-rolled steel was annealed at various temperatures from 850 to 1000 °C for 4 hours and cold rolled to a thickness of 0.5 mm. The steel was final annealed at temperatures varying from 700 to 850 °C for 24 hours. The textures and magnetic properties of the steel sheets were characterized by electron backscatter diffraction (EBSD) and Epstein frame techniques, respectively. It was found that hot band annealing at 850 °C for 4 hours followed by final annealing at 800 °C for 24 hours resulted in the lowest core loss (60 Hz, 1.5 T) of 3.59 W/Kg, which is 26% lower than the core loss obtained without hot band annealing (final annealing at 700 °C). Correlations among the magnetic properties, grain size and texture factor were evaluated for all the annealing conditions to discuss the effect of the annealing conditions on the magnetic properties. |
