Process for producing grain-oriented electromagnetic steel sheet |
摘要 |
In the secondary recrystallization of a grain-oriented silicon steel sheet, a specific temperature gradient is generated, thereby developing the secondary recrystallized grains having a good (110) [001] orientation and increasing the magnetic flux density higher than that previousy obtained. The temperature gradient is established at the boundary region between the primary and secondary recrystallized regions, with the result that highly oriented (110) [001] secondary recrystallization nuclei preferentially are caused to develop.
