Title
Effect of Tin on the Core Loss of non - Oriented Electrical Steel
박종태Jong Tae Park, 우종수Jong Soo Woo
Abstract
To reduce the core loss of the non-oriented electrical steel sheet containing 3.1wt% of Si, Sn was added and its effect has been analyzed. The core loss of the specimen monotonically decreases with the increase of Sn up to 0.22wt%. Major reason for the reduction is found to be due to fact that the addition of Sn enhances the development of (110) crystallographic plane parallel to the rolling plane at the expense of (111) plane. The average grain sizes of the specimens, another important factor on the core loss, remain between 40㎛ and 53㎛ and do not show any significant variation due to the Sn content.
