摘要：
In this work, microstructures of two kinds of heatproof grain⁃oriented silicon steel were investigated by OM and EBSD technique, and the change evolution of microstructure and heatproof mechanism under different annealing temperatures were studied. The results show that small grains and ‘gap’ were formed in the strip surface by toothed roll groove method, and ‘V’ shaped groove was formed in the strip surface by laser irradiation method. The heatproof temperature of laser irradiation grain⁃oriented silicon steel was about 850 ℃, and the heatproof temperature of toothed roll groove grain⁃oriented silicon steel was about 800 ℃. The former has better heatroof. With annealing temperatures increased, the iron loss of two strips increased gradually. For toothed roll groove grain⁃oriented silicon steel, it's mainly due to the decrease of misorientation difference between the notch area and the Goss grains on both sides, while for laser irradiation grain⁃oriented silicon steel may be related to the change of Goss orientation near the groove. © 2023 Cailiao Daobaoshe/ Materials Review.
