| Abstract |
The effects of sulphur content and hot-band annealing temperature on the magnetic properties of non-oriented electrical steels containing 3.1 wt% of Si were investigated in the range of 12ppm∼120ppm in sulphur content and 950℃∼1100℃ in hot-band annealing temperature. It was found that the lower the sulphur content was, the less core loss was obtained due to the increased grain size. In the same manner, the increase in hot-band annealing temperature improved the core loss value as well as the magnetic induction. However, the improvement was found to become less pronounced as the sulphur content decreased. |
