| 英文摘要 | Grain-oriented silicon steel is a key material used for iron cores of transformers because grain-oriented is most desirable for magnetic cores. With the rapid development of modern power industry, the requirement for grain-oriented silicon steel with lower magnetostriction and iron loss have exigent. Although the application of laser-scribed technology can effectively reduce iron loss by refining main magnetic domain in high permeability grain-oriented silicon steels, the influence of laser-scribing on the magnetostriction of grain-oriented silicon steel is still controversial due to the complex magnetic domain structure led by interaction among crystal orientation, surface tension and scribing parameters. In this work, a magnetostriction model for laser-scribed grain-oriented silicon steel is proposed based on the relationship between magnetostrictive coefficient and two kinds of 90 degrees magnetic domain, stress closure domain and transverse domain, and the interaction effects of laser scribing parameters and orientation deviation angle (tilt angle of [001] easy axis out of sheet surface) are analyzed. The orientation deviation angle determines which 90 degrees domain structure of either transverse domain or stress closure domain acts as the dominant factor for magnetostrictive behavior. The stress closure domain and stray magnetic field introduced by laser scribing can reduce the magnetostriction coefficient originated from orientation deviation angle. The theoretical calculation on the effects of laser-scribed energy density and laser-scribed spacing on magnetostriction coefficient is in agreement with the direct experimental measurement. The proposed model concerning the interaction between laser-scribing parameters and orientation deviation angle can provide the theoretical basis to reduce the noise of laser-scribed grain-oriented silicon steel. |
