摘要:
An extra-low iron loss grain oriented silicon steel sheet is produced by irradiating electron beam to an insulation coating formed on a grain oriented silicon steel sheet after finish annealing in a direction crossing the rolling direction of the sheet, whereby the magnetic properties are not degraded even if the steel sheet is subjected to a strain relief annealing. If necessary, an inert gas may be introduced into the vicinity of electron beam irradiated zone of the coating.
