Development of Production Technologies for Grain-oriented Silicon Steels
The development history and the characteristics of the production technologies for grain-oriented silicon steels were described,the control principle of the production technology for grain-oriented silicon steels by nitriding method was especially explained.Besides,the preferential environment for sharp Goss textures {110}<001>to be generated by natural selection,inherited directionally and grown up preferentially was discussed.Actually secondary recrystallization of grain-oriented silicon steels was achieved by the inhibitor,near-constant,whose essence was innate inhibitor,namely AlN near-constant and AlN near-constant formed by acquired nitriding,together with the directional inheritance of Goss textures.
