Method of producing grain oriented silicon steel sheets having excellent magnetic properties.

摘要

The magnetic properties, particularly magnetic flux density of a grain oriented silicon steel sheet are considerably improved by continuously and/or stepwise forming regions, wherein a temperature difference of a secondary recrystallization starting temperature in widthwise direction and/or longitudinal direction of the steel sheet is within a range of 10 DEG C to 200 DEG C, in the steel sheet at a stage before the secondary recrystallization annealing step.
